When leaving Tianpeng Cave, Yang Yi did not take Xiao Hei away.

He gave Xiao Hei an order, asking it to follow the team of the prehistoric alien species for a while.

Anyway, Xiao Hei has also learned the basic breathing method. With this breathing method, it can practice to the third level peak.

Yang Yi has observed that in the Demon Saint Palace, the prehistoric alien species can only be upgraded to the third level peak at most.

The third-level supernatural alien species, after leaving the prehistoric environment, is equal to the Divine Tribulation Realm.

But it is obvious that once the prehistoric alien species really reaches the third level, they will be completely unable to leave the Demon Saint Palace.

The rules of heaven and earth in Tianyao Mountain are that life forms that exceed the Divine Tribulation Realm are not allowed to appear.

Of course, this rule does not include the prehistoric environment.

If you still want to stay in Tianyao Mountain, you will not be able to break through to the third level.

Not only him, but other heavenly tribes here obviously know this rule.

In fact, the Yang Tiansheng had reached the second-level perfect state two days ago.

In the past two days, he has been collecting the spiritual liquid of the prehistoric world from his sub-divine realm.

But his charging efficiency is obviously incomparable to Yang Yi.

In the past few days, Yang Yi's power of the prehistoric world has been increased to the middle stage of the second level. According to his estimates, the prehistoric spirit liquid stolen from the Shennong Cauldron should be able to support him to the peak of the second level.

As for the spiritual liquid collected in the earth-sized form, it should be enough to transform a ferocious beast or star insect into a second-level perfect supernatural alien species.

After leaving Tianpeng Cave, Yang Yi did not leave too far, so he found a collapsed building nearby, hid in one of the ruins, hid himself, and then started practicing here.

As Yang Yi expected, the prehistoric spiritual liquid in the Shennong Cauldron was directly refined into thumb-sized pieces of prehistoric Yuan crystals.

After counting it, it was more than 3,000 yuan, far exceeding my previous estimate!

Judging from this number, if you upgrade to the second-level perfection, you can still have more than half of it left!

This is indeed beyond Yang Yi's previous expectations.

He immediately took out one piece, held it in his hand, and then tempered it and absorbed it according to Lianshan Yijue's breathing method.

This thing that has been refined into the Yuan Crystal of the Great Wilderness is easier to absorb than the Spiritual Liquid of the Great Wilderness.

During the breathing, strands of extremely pure and prehistoric aura were sucked into his chest and abdomen along his pores.

At this time, in order to prevent being noticed, Yang Yi incorporated the tempering of the innate Bagua into his body.

In a blink of an eye, six days have passed.

After six days of continuous tempering and absorption, after spending nearly a thousand pieces of the prehistoric Yuan Crystal, Yang Yi's prehistoric power finally reached the second-level perfection level.

His physical realm also reached the perfect state of immortality.

The immortal body at the level of Dacheng is not only the heart that becomes an immortal heart, but his internal organs are all tempered into immortal organs.

This is the most difficult part to temper, but now it has been tempered to reach the immortal realm.

It is no exaggeration to say that Yang Yi has now truly reached the state of regeneration of broken limbs.

However, the so-called blood rebirth is obviously not yet achieved.

After the power of the prehistoric world reached the second level of perfection, Yang Yi's body suppression was finally all lifted.

However, here, all magical and magical means can burst out with extremely limited power.

Generally, the magical powers that can reach the overwhelming power of the sea can be achieved in the outside world, and at most, it may be possible to directly cut off a prehistoric plant.

Such an environment is just right for tempering magical powers in all aspects.

Yang Yi took out the Burning Spirit Purple Flame that he obtained in Chishakuiyuan some time ago and the Burning Spirit Purple Sunburn.

He first took out the Burning Purple Sunflower plant and threw it into the Shennong Cauldron.

As the magic trick was activated, Shennong Ding slowly decomposed the Burning Spirit Ziyang Kui.

A little bit of dark gray light spots gathered together and gradually condensed into a very strange and terrifying spark.

There were also a little purple light spots that gathered together and condensed into a dark purple flame.

These two different flames, one is the heavenly fire, purple yang fire, and the other is the spiritual fire, the spiritual fire.

When the Shennong Ding decomposed and restored the origins of these two types of flames, Yang Yi was right next to him and used the magic method of swallowing fire.

On the Shennong Cauldron, the two flame mark patterns gradually lit up.

One turned into dark purple and the other turned into dark gray.

Coupled with the silver-white flames that were already lit, the three flame marks on the Shennong Cauldron were all lit.

This is the real three fires of heaven, earth, man and man. Now they are all refined by Yang Yi through the Shennong Cauldron.

A 30,000-year-old fiery purple sunflower made Yang Yi analyze it for two days before he completely analyzes and absorbs it.

Yang Yi obtained two different fire seeds respectively.

During this process, Yang Yi also took the time to let his earth flame fire spirit directly swallow the fiery spirit purple flame, and finally broke through to the level of fourth-grade earth fire and became a real immortal flame.

The three fires of heaven, earth and man are the strongest at present, the Earth Flame Fire Spirit, which has reached the fourth level.

The other purple Yang Fire and Burning Spirit Fire are only third-grade, and they are still far from the fourth-grade.

If you want to improve, you naturally need to continue to look for other strange fire seeds of heaven and human fire in the future and swallow them.

These three types of flames are all improved and tempered in the prehistoric environment, and their strength is naturally improved to a certain extent.

After doing all this, Yang Yi walked out of his hiding place.

Unfortunately, I don’t have a handy weapon now. The Dragon Bone God-killing Sword is a magical weapon, and there is no way to use it in such a place.

The divine consciousness he recovered was suppressed here, which was not enough to support him in the sword control.

If you want to activate a magical weapon like the Dragon Bone God Slayer Sword, you don’t have to think about it if you have a divine thought.

Besides, Yang Yi did not want to reveal that he had a magic weapon in his hand unless he had no choice.

Any magical artifact is enough to cause shock to the heavens.

After walking out, Yang Yi simply didn't take any weapon, and took his hands empty-handed and went to Tianpeng Cave to take a look.

It's become a mess here.

The ancient spiritual liquid in the cave has naturally dried up, and many shocking dry blood can be seen on the ground.

However, no corpse was seen, and no corpse was left behind, whether it was the prehistoric alien species or the heavenly race.

After surveying, Yang Yi followed the traces left by one of them and chased them all the way.

After half a day, after chasing for hundreds of miles, the expression on Yang Yi's face became quite serious!

The direction these Tian Clans are actually on the same path as the direction they were planning to go before!

"Is it possible that these heavenly races are entering here for that thing?"

Yang Yi thought to himself with a slightly frown.

Although I came here by chance this time, since I came here, Yang Yi naturally hoped to get the most valuable treasure here.

This thing is the real treasure of the Demon Master’s Mansion - the Ten Thousand Demon Flags!

This treasure was extremely famous in ancient times. It is said that it can command the demon gods to obey orders, and can also add the demons to the order flag to train the demon army.

However, it is not easy to get this treasure.

It is hidden in the central treasure house of the Demon Master's Mansion.

Not only are there many bans there, but the flag itself also has an extremely terrible power to block.

If you are not careful, you may be captured by him and become a member of his control.

After Yang Yi stepped into the center of the Demon Master's Mansion, he ran straight towards the Demon Master's Hall where this treasure was hidden.
Chapter completed!
