This can be said to be greatly beyond Chu Chen's expectations, and it was something Chu Chen had never expected at all!

Of course, Chu Chen thought for a moment and knew that it was probably because of this source energy. If he used other spiritual energy to break through his own cultivation, he would not be so relaxed!

And just as such thought emerged in Chu Chen's mind, Chu Chen suddenly felt a force that suddenly emerged in his body, filling his limbs and bones, and even made Chu Chen's body tremble involuntarily!

"Breakthrough!" This thought immediately appeared in Chu Chen's heart. All of this could be said to be extremely smooth, and even so smooth that Chu Chen couldn't believe it.

But there is no doubt that this is the case. After absorbing this source energy, one's own cultivation level can be said to have made a very smooth breakthrough!

"This is the case with this source energy. Because it was born from the fallen monk, it is actually much easier to absorb and use for practice than other spiritual energy!" At this moment, Ye Qing's voice came from the Chaos Ten Thousand Spirits Tower, informing Chu Chen.

After hearing this, Chu Chen naturally nodded slightly, and naturally understood what Ye Qing said. After all, Chu Chen personally felt that after absorbing this source energy, the changes in his practice can almost be said to be twice the result with half the effort. Compared with spiritual energy, I don’t know how many times better!

At the great perfection of the Nascent Soul, Chu Chen slowly opened his eyes, and a glimmer of light flashed deep in his eyes, which could be said to give people a breathtaking feeling!

Chu Chen naturally felt that his own power was filled with spiritual energy, as if the whole body was flowing. Obviously, Chu Chen had almost completely finished this first step in cultivation, and what he needed to consider next was to enter the second step of the cave realm!

Of course, after Chu Chen broke through his own cultivation level, Chu Chen also turned his gaze to Feng Yan next to him.

Chu Chen also saw that at this moment Feng Yan struggled, Feng Yan's eyes closed, as if it was extremely difficult. Chu Chen also felt that Feng Yan's breath was disordered. Obviously, under such circumstances, even with the help of the source energy in the token and the elixir given by Chu Chen, Feng Yan's breakthrough path was not easy.

Of course, Chu Chen was not surprised by this. After all, what Feng Yan needed to break through was not like Chu Chen, from the late stage of the Nascent Soul to the Great Perfection of the Nascent Soul, but from the first step of cultivation, directly entering the second step!

The breakthrough in this can not be simply described in words. Even if it absorbs the source energy, it can reduce the difficulty of the breakthrough. However, in fact, once it breaks through, the difficulty in it is extremely high!

"There should be no problem!" Chu Chen slowly expanded his spiritual sense and landed on Feng Yan's body!

Naturally, Feng Yan was almost invisible under Chu Chen's gaze at this moment, and was completely completely seen by Chu Chen. After such investigation, Chu Chen naturally realized that although Feng Yan seems to be extremely difficult to break through this realm, there will be no major problems in fact!

At least in Chu Chen's opinion, it is impossible to make any mistakes. Although it may take some time to completely enter the realm of the cave, Feng Yan at this moment undoubtedly has no problem and it is impossible to make any mistakes!

"Not bad!" Chu said in his heart. Obviously, in Chu Chen's opinion, Feng Yan's talent for cultivation is also an extremely good existence! And now, Chu Chen naturally sat down cross-legged and silently waited for Feng Yan's breakthrough!

During this period, Chu Chen also felt the changes in his own realm, although he only broke through from the late stage of the Nascent Soul to the Great Perfection, the name here is not as simple as this. After all, once he breaks through to the Great Perfection of the Nascent Soul, it can almost be said that the first step of cultivation has been completely completed!

This is the case at the moment, and in this way, what Chu Chen naturally needs to think about is how to enter the second step of the cave realm!

After all, because what you are practicing is a perfect state, it is probably extremely difficult to enter the second step of cultivation, at least in Chu Chen’s view!

"I don't know what this place of trial is, but it seems that there must be many opportunities and creations in this place!"

"If I want to take the second step of my practice in this trial land, it should be a big problem!"

"But because I need to enter the second stage of realm, the opportunity and creation of the realm of Cave Heaven is probably also the object of many geniuses Daozi, among which there should be many existences like the Heavenly Desire Palace. Naturally, the difficulty here is quite large!" Chu Chen said in his heart, and he also quietly thought about these things.

Of course, although Chu Chen felt a little tricky, he had no intention of giving in. Even if the power of the Heavenly Desire Palace was so huge, in Chu Chen's eyes, he didn't need to take it seriously!

Time passed slowly, and three days passed. Chu Chen and Feng Yan had already stopped for ten days. Finally, Chu Chen also felt that the breath in Feng Yan's body beside him had some changes!

As he absorbed the source energy in the token and took the Breaking Realm Pill given by Chu Chen, after ten days of practice, Feng Yan also had a different aura. It was the breath of a cultivator in the second stage of cultivation, completely different from the breath of a cultivator in the first stage of cultivator. Chu Chen, who was beside him, naturally saw Feng Yan's changes completely.

Although the process in between was a bit extremely difficult, it seems that there is no problem now. Chu Chen has already seen that Feng Yan has almost completely entered the second step of the cave realm.

However, my own aura seems to be unstable and needs some adjustments!

At the moment, Feng Yan still did not open his eyes, and was obviously immersed in the practice. This made Chu Chen feel confused!
