Wang Lun was curious about why the Demon Blood Vine King knew so much about the black box. He could have this kind of understanding without seeing the box. Either he had really obtained this information through some means, or he was just making up random things.

The Demon Blood Vine King was restrained and felt that Wang Lun's big hand was still above his head, and he would launch a second soul search method at any time. This is the helplessness of being controlled by others.

It no longer wants to be searched for the soul. It did not resist Wang Lun's question and answered directly: "I have obtained the Sumeru Stone, which is the material for refining the black box, and it was obtained in the depths of the ancient man swamp. If you allow me to restore some magic power, I will show it to you."

"Is there such a thing? So you don't know anything about the black box at all?" Wang Lun felt strange.

"Nothing is strange. Now it seems that the Sumeru Stone was probably dropped from the special space hidden in the black box, but I couldn't think of it at that time." The Demon Blood Vine King explained.

It knows the small stones hidden on it are the Sumeru Stones, which are the ones that are the Sumeru Stones themselves. There are not many people in the spiritual world who have heard the name of Sumeru Stone. There are even fewer people who know that the magic weapons refined by Sumeru Stone have automatic space restrictions. On this basis, there are probably only a few cultivators who know to use the Shunbian Divine Stone to break this kind of space restrictions. After all, whether it is the Sumeru Stone or the Shunbian Divine Stone, it is estimated that there are only a few pieces in the spiritual world.

What it said to Wang Lun now is not everything it knows. In the case of death, it will not let Wang Lun open the black box. Even if Wang Lun really finds the Sky-breaking Divine Stone, it cannot meet the conditions for violently breaking the black box.

"Does the small stones I own the same material as the black box? You can compare them." The Demon Blood Vine King continued.

Wang Lun felt that if this was true, it would be possible to explain why the Demon Blood Vine King could have given the key information before.

Now the other party asked to recover some mana, and he directly met this requirement. Anyway, the Demon Blood Vine King can't fight back successfully no matter what he does.

“That’s it.”

After the Demon Blood Vine King discovered that his magic power had recovered a little, he let the magic power wander in his body quickly, alleviating the pain in his body. At the same time, a black thing about the size of a fingernail flew out of its vine-shaped body.

This thing has an irregular shape, but the surface is very smooth and there are no scratches.

"It looks the same." Wang Lun said so after getting the hand to compare.

Of course, if this thing is a Sumeru stone, it cannot be tested. It is not like a black box that has been refined and has produced a space effect. It only has space attributes.

Wang Lun tried to include it in the storage ring, but it failed.

However, the inanimate materials that cannot be included in the storage ring are not only Sumeru stone, so it cannot be concluded that this is Sumeru stone.

"Believe it or not depends on yourself."

The Demon Blood Vine King's words mean something, "Just as if you don't believe that I will keep the secret."

“It’s almost the case.”

After Wang Lun said this, before the other party was ready, a large amount of mana suddenly rushed into the other party's body and exploded directly, killing the other party in an instant. The Demon Blood Vine King suddenly died without any pain.

After fulfilling what he said, Wang Lun pulled the body of the Demon Blood Vine King out of the Corpse Lake. After the other party died, the body returned to normal, very large, and the long vine was like a long dragon that could not move.

Wang Lun checked the other party's flesh sac and found nothing. However, the Demon Blood Vine King himself was not trying to obtain the treasure. Wang Lun buried the other party nearby and then returned to the Corpse Lake.

Nothing else, just because today happens to be the "Spirit Moon Sun". By dawn tomorrow, he will have about five hours to arrange the magic array. After all, it is already seven or eight o'clock in the evening, and it is dark. The seven hours during the day are actually considered in the "Spirit Moon Sun". However, he was fighting with the Demon Blood Vine King at that time.

The Corpse Lake is a relatively special place after all. Wang Lun thought that instead of spending time looking for other special places, he might as well choose this place directly. It takes time to go to other places. It is only five hours to barely be able to use it. When you find a suitable place, you will probably only be able to arrange the enlarged magic array in one or two hours.

No monsters appeared around the Corpse Lake. Even though there had been a lot of noise here before, it saved Wang Lun the time to check around him first.

At the bottom of the lake, Wang Lun quickly replenished his magic power with the top-grade spirit stone so that he could be energetic when setting up the formation.

While absorbing the spiritual power from the spirit stone, Wang Lun thought about the black box. First of all, it is certain that the words of the Demon Blood Vine King should not be fully believed.

Even if I really have a way to get the Knight Breaking Stone from Qizhen Pavilion, I guess I can't open the box.

Secondly, even though he knew it was like this, he had to find a way to get the Divine Stone of Breaking the Sky first.

This is difficult to do, he knew. Qizhen Pavilion must have treasured such things, and it is estimated that the method of using other things to trade with Qizhen Pavilion will not work.

"Take the black box back to the spiritual world first, find a place to hide it properly. The rest is to find opportunities to get the Sky-Breaking Stone."

Wang Lun has something to do and thinks he must do it well. Only by opening the black box can he get the Tiantian Sword inside, so that the power of the Seven Swords of True Spirit can be truly exerted.

After all, it is okay to rely solely on the Spinning Sky Spear to counter or even suppress practitioners of the same level. It is almost impossible to kill. He needs to enrich his offensive arsenal. Although it is not expensive, it is not too much to have a magic sword based on the Spinning Sky Spear.

Wang Lun and others recovered their magic powers. It took only about twenty minutes before they immediately started to set up formations at the bottom of the Corpse Lake.

The area of ​​this lake is not large. According to the nine-hour array deployment time, each array deployment takes about seven minutes and can be arranged about seventy times, so the bottom of the lake can be divided into seventy areas.

This is the smallest area of ​​the divided area that Wang Lun encountered since he set up his formations. In the past, he set up a formation in other special places, and the area of ​​the divided area is several times larger than this, or even thirty times larger.

The smaller the area, the higher the accuracy of the array. However, it is still unknown whether there is high-level energy in this place. Wang Lun did not think about anything else, and began to start from

The center of the lake bottom begins.

Take out the array flag and insert it, then release the magic power to activate the array flag, so that the essence of the world can be connected to the amplified magic array, and then soon there are light spots between the array flags on each side to form a line...

Wang Lun is extremely familiar with the process of setting up the array. Now he can operate with his eyes closed. However, the most time-consuming thing in setting up the array is to adjust the oscillation frequency. This cannot be accelerated and it must take a fixed period of time. Therefore, no matter how skilled the array is, he will have to finish testing once, and it will take about seven minutes.

The enlarged magic circle was arranged in the Corpse Lake, but the Corpse Lake did not become any different because of the death of the Demon Blood Vine King and the appearance of Wang Lun. It was still dead silent here, and even the sound of birds only appeared far away.

Wang Lun quietly set up the formation, and soon four or five hours passed, and there was no gain. Instead, he found a lot of bones. These bones must be powerful cultivators who can only be buried in the mud for so long and still exist after such a long time of corrosion.

There are no magic weapons at the bottom of the lake except bones. Obviously, this battlefield has been cleaned up long ago, and any useful things have been taken away. Wang Lun endured the unpleasant smell at the bottom of the lake and continued to set up the formation. After all, it only takes one day in a month to set up the enlarged magic array. Today is lucky. When he encounters it when he is free, he can do it with confidence, and of course he should cherish it.

In short, he hadn't gotten a chance for several months before.

Wang Lun had already arrived at the west position at the bottom of the lake. He started from the middle position, then went east, and then north, turning counterclockwise to the west side. The thickness of the silt here is much smaller than the center position. The array flag is inserted here, making it easier to attract the essence of heaven and earth, but it seems to have no effect on the result. He set up the formation here five times in a row, but the array flag did not react.

As time continued to pass, Wang Lun finally moved to the south. As long as he explored this area that occupied about one-sixth of the bottom of the lake, it would be until dawn.

With one magic array after another, the array was naturally very smooth. After all, the technology was very mature and there were no obstacles. Before we knew it, Wang Lun found that there were only ten areas left without investigation.

I guess this hasty and temporary formation operation will fail.

When the fifth last area was reached, the array flag had been laid out, and Wang Lun was mediating the oscillation frequency, from low to high. At this moment, the array flag in front of him suddenly reacted without warning and was shaking uncontrollably, as if there was some force surging under the mud inserted under the array flag pole and was about to wake up!

Wang Lun's body immediately tensed, his eyes widened, staring at the reaction of the formation flag, keeping the frequency of the oscillation at this moment unchanged.

After one second, the oscillation was still on the three array flags in the lower left corner, and it was not transmitted to the surrounding array flags.

It seems that the high-level energy below is in a relatively stable state and is not moving.

If the high-level energy is moving, it takes less than a second, and in one tenth of the time, the oscillation will shift from the current array flag to other array flags, or even directly to areas where there is no array layout.

Compared to the high-level energy that can move, Wang Lun must like this kind of fixed staying more.

What surprised Wang Lun was that the time when the oscillation occurred on the three array flags was extended from one second to two seconds, until the fourth second, the amplitude of the vibration of the array flag began to decrease and then it stopped.

"The oscillation frequency has changed, but the change speed is much slower than I thought."

The high-level energy under the corpse lake is relatively stable and hardly moves, but it must be surging all the time. When moving, the oscillation frequency will often change, and it is impossible to be fixed at a certain frequency. According to Wang Lun's experience, a frequency lasts for two seconds is the limit. Unexpectedly, it has been almost four seconds now!

Wang Lun tried to increase the frequency, but did not find it. When the oscillation frequency was reduced by a small amount, he found it again, and the three-array flags in the lower left corner were still vibrating.

After two successful discoveries, Wang Lun confirmed that there was a high-level energy below the three-array flags.

Now is the time to determine how big the area is.

"I didn't expect that I was so lucky!"

"High-level energy will be found in places like Corpse Lake!"

Wang Lun could not control this excitement and joy at all, and the smile on his face could not stop at this moment.

He was really unintentionally planting willows and willows, but the hasty formation operation suddenly gained something. He would be happy at any time, let alone in this corpse lake. There would be no cultivators coming here, which means that after discovering high-level energy, there would be no need to worry about being occupied by others.

Wang Lun began to re-arrange the formation in the adjacent place. This was the fourth last area. As a result, after the formation was completed, he found that the formation flag was vibrating again when he was leaning against the previous three array flags.

In fact, this is something that can be guessed. Since the high-level energy below is almost motionless, if only the area formed by three array flags reacts, and no other place responds, the area of ​​the high-level energy will be too small!

Wang Lun also investigated the last few areas and finally roughly judged that the area of ​​high-level energy is about the size of a badminton court.

In the past, Wang Lun had contacted two secret places containing high-level energy. One of them had very little high-level energy content, much less than the current one. So Wang Lun was still very happy at this moment. If the high-level energy inside the secret places as big as a badminton court was absorbed by the Ten Thousand Spirits Bottle, it should be enough to use the space beacon to activate the space transmission more than five times.

After determining the size, the next step is to determine the exact location, including the depth.

This was a bit difficult. Wang Lun began to hold the Spinning Sky Spear in his hand, relying on his own physical strength, instead of using mana to activate the Spinning Sky Spear, digging into the sand and rock layers under the silt.

Because I don’t know how deep the high-level energy is located below, I rashly use my mana to activate the rotating sky spear to open the way downward. Once the mana attached to the rotating spear comes into contact with the high-level energy and unfortunately detonate it, I will die.

Now, digging with simple force is definitely much slower, but at least it can ensure safety. Wang Lun worked hard for about two hours and dug down about thirty meters. During the process, he activated the Ten Thousand Spirit Treasure Vase twice, but did not see the reaction of the Treasure Vase, which means that the high-level energy is still deeper and has not been connected to the Treasure Vase.

Contact.

The Spirit Moon Sun has passed, and he can no longer use the amplified magic array to detect high-level energy. Fortunately, there is also the Ten Thousand Spirits Vase.

When he dug down to about fifty meters deep, Wang Lun activated the Ten Thousand Spirits Treasure Vase again. At this time, the Treasure Vase was directly escaped from Wang Lun's hand and was about to swallow high-level energy. Wang Lun was prepared and quickly summoned it back, forcibly retracted the Treasure Vase, stopped activation, and made it silent, turning it into the mark of the Treasure Vase to disappear.

If you don’t do this, the high-level energy here will be swallowed up by the whale in an instant.

Wang Lun did not intend to get the Ten Thousand Spirits Ark to obtain these energy.

So far, he still hopes that the Ten Thousand Spirit Treasure Aviary can absorb enough high-level energy to awaken the spirit of the instrument and even restore the treasure aviary. However, Wang Lun wanted to use other aspects of this secret place discovered today.

The reason is that the high-level energy in this secret place is very stable, almost does not move, and stays in a fixed place and can be used at any time, maybe it will be fine after three or five years.

If you take a step back, you won’t be able to use this secret place in the future. Then he will have time to let the Ten Thousand Spirit Treasure Bottle absorb the high-level energy here.

After determining the size and location of the secret place, Wang Lun remembered it firmly and began to move upwards, clearing the traces while moving, filling the channels he dug out, and not allowing people to find clues casually.

After arriving on the silt layer of the Corpse Lake, Wang Lun cleared the surrounding traces one by one. When he flew from the Corpse Lake to the shore, the cleanup traces had been going on for almost two hours.

Now the traces of fighting in the Corpse Lake and the traces of his visit have been erased. Except for the devil blood vine king, everything else is no different from before he came.

Wang Lun did this to make the Corpse Lake still a place of disgust in the eyes of cultivators. After all, the Demon Blood Vine King is dead. The Golden Eagle Demon and the Cloud Leopard Demon will not be able to contact the Demon Blood Vine King. If something happens to the other party, he will definitely come to the Corpse Lake.

Now Wang Lun is not afraid of them coming, and those big monsters cannot find high-level energy after they come.

As for the place where the Demon Blood Vine King was buried, Wang Lun took a walk and cleared the traces there. Then he immediately rushed into the sky and began to fly quickly towards the human world.

I have been in the Monster World for a long time, so I have to hurry up on the way back.
