The four marginal matters are very mysterious. This is something that Wang Lun can confirm.

At that time, the Dragon Spirit Venerable always insisted on not violating the river with the people in the four borders, and did not attack the four borders for the Ling Sect to obtain cultivation resources.

Even after coming out of the four boundaries, even the most trustworthy spiritual pet Marshal Tianling and Venerable Long Ling did not tell the other party about his experience in the four boundaries.

What is certain is that people in the four margins have the ability to keep the biggest secret. Over the past tens of thousands of years, whether it is Ling Sect or other sects, they cannot control the four margins, nor can they communicate with the human cultivators inside.

"If you want to talk about the real isolation from the twelve sects, there are the four major margins."

Wang Lun said silently in his heart.

People from the twelve sects cannot reach that long.

Wang Lun was naturally very interested in the Four Elements. After all, if he assumed that after his ultimate action was over, the Four Elements were the only place he could get rid of the pursuit. However, Marshal Tianling was unwilling to talk about the Four Elements, and Wang Lun had no choice.

After drinking, Marshal Tianling flew away directly, and Wang Lun also chose the right place to start resting.

After resting for a few hours, Wang Lun continued to arrange the enlarged magic circle. Today is the 16th day, and the middle area of ​​the forbidden area has basically been explored.

Although the probability of high-level energy appearing in the core area is theoretically higher, and when it is approaching the end, the probability of gaining is very small, Wang Lun did not lose his enthusiasm.

When setting up the array, it was still serious and meticulous, and the speed did not slow down.

The amplified magic array in front of him had reached the maximum oscillation frequency. When the light connecting the array flag automatically collapsed, Wang Lun also stood up and ended his squatting and waiting state.

The magic array collapsed and the array flag did not tremble, which means that the magic array could not sense high-level energy.

Wang Lun flew to the area next to him.

Still planting array flags on the ground, confining the yin energy, and activating the array flags...

Wang Lun squatted in front of the formation flag and gradually increased the oscillation frequency of the magic array.

Suddenly, Wang Lun's eyes widened, his eyes quickly focused, and he focused on the two array flags in the upper left corner. Just in the moment, he caught the two array flags trembling.

The leftmost array flag is a little larger than the other array flag.

Although the tremors of the two array flags can be almost ignored, compared to the motion of the other array flags beside them, Wang Lun was sure that he was not dazzled.

But after waiting for a second, the two array flags remained still and had no reaction.

Wang Lun immediately increased the oscillation frequency rapidly and observed all the array flags at the same time.

High-level energy is always active, with vibration frequency and not fixed, but relatively speaking, it will stabilize in a range in a short period of time. It needs to continue to let the frequency of the array vibrating resonate with it before the array flag will continue to react.

The oscillation frequency of the magic array increased rapidly, but the array flag still did not respond. Wang Lun immediately lowered the oscillation frequency, hoping to capture the array flag's reaction again.

Five seconds later, there was still no movement.

Wang Lun directly sacrificed the Spinning Sky Spear, and the Spinning Sky Spear was rotated, and the spearhead was aimed at the ground.

At this time, Marshal Tianling also saw the movements from Wang Lun and hurried over and asked, "Have you discovered it?"

Wang Lun nodded and had no time to speak. He followed the Spinning Sky Spear to enter the underground. The Spinning Sky Spear opened the way underground. He followed behind. All the soil, sand and gravel brought by the Spearhead were thrown to the rear, blocking the passage behind him along a parabola.

The spiritual consciousness was released with all its strength, and Wang Lun also took out the Ten Thousand Spirits Vase from the storage ring and held it in his hand. The Swirl Spear opened the way and had magic power to provide energy. If the magic power came into contact with high-level energy, it might trigger the latter's explosion, which was enough to kill all the powerful god-transforming people. However, with the Ten Thousand Spirits Vase, the situation was completely different.

When the Ten Thousand Spirits Vase is activated, as long as it encounters a high-level energy, it will actively swallow it. Moreover, before the whale swallows, the bottle body will also change. Just observe the changes of the Vase to know whether the high-level energy is nearby.

.

So now he is pursuing high-level energy, but he actually relies on the Ten Thousand Spirits Treasure Bottle. Whether his spiritual consciousness or vision, he cannot find high-level energy.

After all, even if the high-level energy is very close to it, ordinary monks cannot discover it even before they are self-destructed.

"The high-level energy I just discovered is active and disappears from the amplified magic array in an instant."

"If it moves very fast, even if I chase it with the Ten Thousand Spirits Vase, I will not be able to catch up."

This is also why Wang Lun had previously raised the oscillation frequency of the magic array, and immediately got into the ground to chase after he found that he had no response.

High-level energy is in a moving state and is difficult to track.

Of course, maybe it was moving quickly the moment before, but the movement speed of the next moment was greatly slowed down, or even stopped.

Wang Lun was moving towards the upper left corner in the horizontal direction, because both array flags were arranged in the upper left corner, and after each trembled, the other array flags did not respond, and the high-level energy was definitely not moving towards the lower left corner.

After chasing for a while, the Ten Thousand Spirits Basin did not react at all.

"The treasure oak must be very close to high-level energy before it will react." Wang Lun only knew that the Ten Thousand Spirit Treasure Ark had not discovered high-level energy yet, so he gritted his teeth and continued to chase forward.

A few minutes later, seeing that there was no gain, Wang Lun changed direction, which was actually just a blind eye to his luck.

After all, the direction of movement of high-level energy is completely unrecognizable.

After working underground for about ten minutes, Wang Lun came out.

Marshal Tianling looked over and saw Wang Lun shaking his head at it, and laughed: "High-level energy also has times when it is still, but it is not so easy to touch."

Wang Lun himself would not sigh when he missed the high-level energy. He had tried his best to investigate so many times before but had no results, so he realized that it was not that luck would always be on his side.

But now he is the "Elder of Lingzong", and his actions must be different.

Wang Lun showed a disappointed look and shook his head and said, "It's almost a pity, it's a pity."

Marshal Tianling did not sneer, and understood very well in his heart that this was not a bad thing, and he didn't even catch the high-level energy hair.

It did not say that the other party was so concerned about finding high-level energy, and wasn’t it that the status of the person who had risen after returning to Lingzong to gain merit?

And it doesn't help the other party succeed, it doesn't matter. Of course, if you help the other party get high-level energy, it will only benefit it.

"Continue." Marshal Tianling shouted.

Wang Lun walked back to the place where the formation was deployed, pulled out the formation flag, and went to the next area to continue the formation.

Marshal Tianling's method of setting up formation was not as skillful as Wang Lun, but his speed was not slower. He set up formation next to Wang Lun. Both sides did not speak anymore and were busy.

Soon, more than half of the day passed, and the day ended.

There is no day and night in the ghost world, but in the forbidden area, Wang Lun has been resting until the hour of the day for more than ten days, and today is no exception.

On the seventeenth day, the formation continued, but there was no harvest.

On the 18th day, the formation entered the peripheral area.

According to the current progress, it is estimated that if you add today and tomorrow, you can complete the exploration of the peripheral area. The total exploration time will be about nineteen days.

Marshal Tianling's condition is even better than yesterday, because it is almost over.

Wang Lun was still in a stable state, without any worries about gains and losses, and just planned to explore the remaining areas step by step and seriously.

About one-third of the time passed today. Wang Lun and Marshal Tianling stopped one after another and started to rest for half an hour. When the time came, they continued to set up their formations.

There are also mountains and forests in the outer area, and Wang Lun is covered with trees, and there is no need to set up a formation as close to the border wall, so there is no need to worry about being discovered by ghost generals.

Wang Lun directly discarded the previous set of array flags. He used them too many times, and this set of array flags is no longer suitable for array layout.

.

Light flashed, and Wang Lun took out a brand new set of array flags from the storage ring.

But as soon as the first formation flag was laid out, Wang Lun heard the nearby Marshal Tianling calling him.

"Come here quickly, there is movement!"

Hearing this, Wang Lun was excited and flew over quickly.

In his heart, Wang Lun was naturally wondering whether Marshal Tianling had discovered high-level energy?

After flying over, Wang Lun knew the reason why the other party called him urgently without explaining it with Marshal Tianling.

The 20-square-meter enlarged magic array arranged by Marshal Tianling was trembling slightly in the center of the magic array!

The surrounding array flags did not move, and the comparison was still very obvious to the Nascent Soul monk!

"The high-level energy is below!" Wang Lun couldn't help but shout.

At this moment, Wang Lun was indeed excited. Before looking for high-level energy, he had the intention of leaving all his powers to fate. He had no delusions and would not worry about gains and losses in his heart. However, if he really discovered high-level energy, he still could not control himself and would become excited.

"You go and collect it." Marshal Tianling said, "It took two or three seconds, only these three array flags were moving, and the high-level energy should not move for the time being."

If it doesn't go, it's just too lazy to go. High-level energy has no meaning to it. What it is interested in is whether it can find high-level energy with amplified magic array. It is now proven that it can be found. It has a sense of accomplishment, but if it is not interested in high-level energy, it will naturally not think about obtaining it.

Wang Lun naturally wanted to collect it. The Spinning Spear had been activated, but at this time, Marshal Tianling quickly shouted: "It's actually moving!"

It just said that the high-level energy will not move for the time being, but immediately, the new array flag in the lower right position was trembling, and the previous three array flags stopped!

"I'm going even more." Wang Lun shouted, and the Spinning Spear opened the way, drilled in from the ground next to the enlarged magic circle, and advanced diagonally towards the lower right direction.

"Hurry, go straight over, this array flag is still moving!" Tianling's vital energy sent a voice to Wang Lun, reminding Wang Lun that the high-level energy is still within the coverage of the magic array.

The magic circle is only twenty square meters, and Wang Lun has already reached the ground. Compared with the last time, the situation is much better. The last time, he didn't even determine the specific direction of the movement of high-level energy, and he relied on gambling luck to chase it. This time he had a clear direction, and he even needed to find it within a range of twenty square meters.

Wang Lun diagonally penetrated to the lower right for half a second, not only entering directly below the enlarged magic array, but also reaching fifty or sixty meters.

The Ten Thousand Spirits Vase was held in my hand, but there was no response for the time being.

Wang Lun quickly dug vertically to a deeper place.

Since the high-level energy is below the magic array, it is a question of how deep it is from the ground. He can move it quickly downwards so that the Ten Thousand Spirit Treasure Ark can approach the high-level energy.

Sure enough, when Wang Lun dug into the depth of about two hundred meters, the Ten Thousand Spirits Treasure Bottle suddenly reacted, and the light burst out from the bottle body, and the bottle also flew out of Wang Lun's hand automatically, moving vertically downwards quickly.

Wang Lun immediately braked, stopped his body, and stopped the Spinning Spear. Most of his mana was removed, leaving only a layer of mana shield around his body, fighting against the pressure of the rock layer deep underground. Such a little mana, without attacking, would definitely not interfere with high-level energy and would not explode.

The Ten Thousand Spirits Vase only moved down twenty or thirty meters before stopping. Then, Wang Lun felt a huge force appear beside him.

But he also used his spiritual sense and his eyes, and he could not sense or see high-level energy.

This is the biggest reason why high-level energy is difficult to find. He was standing next to him and could feel the breath of high-level energy, but he could not see or touch it.

Only when high-level energy explodes, the movements created will be discovered by people.

Wang Lun now felt the breath of awesomeness by using the Ten Thousand Spirits Vases.
Chapter completed!
