To be the best leader, you must also be the strongest leader!

The counterattack force that cultivators with low-grade spiritual roots have to endure when breaking through a realm is too strong. Both their body and soul cannot withstand it and they can easily be seriously injured.

The Vitality Pill is very effective in healing the body, but how many young cultivators in the Qi Refining Stage can afford such a precious healing elixir as the Vitality Pill?

Besides, even if there is a vitality pill, what can it do? The soul will also be affected by the counterattack force. If it is not resolved, there is no way to succeed.

The next person was a cultivator named Li Yu who had reached the great perfection of Qi training. He broke through the bottleneck according to Sun Yi's request. The first time he broke through the bottleneck, the powerful rebound force instantly severely damaged Li Yu's body and soul.

Sun Yi quickly asked him to take the foundation-building pill for the second attack.

Although the rebound force of Li Yu's second attack was weakened a little by the Foundation Establishment Pill, it still caused serious trauma to Li Yu's body and soul.

However, with the help of the Foundation Establishment Pill, his situation was obviously much better than Zhang Yuan's. He persisted in breaking through the bottleneck six times before he had to give up.

With the help of five Jindan-stage elders, the violent true qi in Li Yu's body was suppressed. With the treatment of the vitality pill, his physical injuries were recovering rapidly, but the trauma to his soul could not be recovered.

Li Yu's face was pale and he looked lost at this time. He had finally cultivated to the great perfection of the Qi Refining Stage, but even after using the Foundation Establishment Pill, he was unable to break through to the Foundation Establishment Stage. This result was a huge blow to him.

Seeing Li Yu's lost expression, Sun Yi smiled and patted Li Yu's shoulder to comfort him: "Don't be discouraged, I will definitely find a way to help you recover your spirit and soul so that you can break through to the foundation-building stage."

"Thank you, Master." Li Yu forced a smile. In fact, he didn't hold much hope.

"Go and rest over there."

Li Yu walked to the side disappointedly, and then Sun Yi arranged for the last two people to try, but the results were very unsatisfactory.

The cultivator who did not have the Foundation Establishment Pill held on to the end and was also seriously injured like Zhang Yuan. Fortunately, the five elders including Jin Jue were watching nearby and saved his life.

In the end, the cultivator who used the Foundation Establishment Pill also failed to make a successful breakthrough. He persisted until the seventh attempt to break through the bottleneck before giving up, and finally dragged his injured body back to the side.

Sun Yi stood in the training room and pondered for a long time. Elder Jin Jue and the others were waiting quietly beside him. They didn't know whether Sun Yi had a solution.

After a while, Sun Yi raised his head and looked at the five Jindan-stage elders across from him: "Do you know what the bottleneck in our bodies is? Why does a rebound force appear when we impact the bottleneck? Moreover, cultivators of different qualifications experience different rebound forces. What exactly is this rebound force? Why can it act on both the body and the soul at the same time?"

Sun Yi's question made everyone present look at each other in confusion, and no one could answer.

After a moment, Elder Jin Jue gave an ambiguous explanation: "A bottleneck is a bottleneck. Doesn't every cultivator have it?"

"Yes, Master, do you think there is something wrong with the bottleneck?" Elder Qin Chu looked at Sun Yi in surprise.

Elder Han Yun, Elder Ye Luo, Elder Li Tai, and everyone else in the training room looked at Sun Yi with confusion.

Anyone who has embarked on the path of cultivation knows that in order to break through the realm, they need to break the bottleneck in the body. As for what the bottleneck is, they are not clear.

Seeing the puzzled expressions of the crowd, Sun Yi shook his head helplessly. Elder Jin Jue and other cultivators only knew that bottlenecks existed, but had never studied this thing.

It’s like some ordinary people eat eggs but don’t know where eggs come from, because they take it for granted and don’t need to study it at all.

Sun Yi had an idea after observing the internal conditions of eight disciples when they broke through, combined with his own guesses.

He gathered his thoughts and then spoke slowly, "I believe the bottleneck is a shackle bestowed upon each of us by heaven and earth. If we want to break through, we need to break the shackle."

"However, breaking the shackles is against heaven and earth, so there will be a rebound force when impacting the shackles. The rebound force is equivalent to the punishment power of heaven and earth. I call it the power of heavenly punishment."

"The higher the aptitude of a cultivator, the greater their affinity with the heaven and earth. The faster they cultivate, the less punishment they receive from heaven and earth when they challenge the shackles, and the easier it is to break through the realm."

"On the contrary, the worse your aptitude, the weaker your affinity with the world, the slower your cultivation speed. When you challenge the shackles, the stronger the punishment you will receive from the world, and the harder it will be to break through the realm."

This was the first time Elder Jin Jue heard Sun Yi's novel statement. Although it seemed a bit far-fetched, he felt it made a lot of sense after thinking about it carefully.

"Master, what you said seems to make sense."

Qin Chu frowned thoughtfully: "Could it be that the bottleneck in the cultivator's body is really the shackles bestowed upon us by heaven and earth?"

"But Master, does heaven and earth really exist? Can they really put shackles in our bodies?" Elder Ye Luo asked with a puzzled look.

Sun Yi smiled and explained, "I've read in the sect's textual records that top cultivators who wish to ascend to the higher realms must endure a heavenly tribulation. If heaven and earth don't exist, then where does this heavenly tribulation come from?"

"Hearing what the master said, it really makes a lot of sense. I didn't expect that there are shackles given by heaven and earth in our bodies. How did heaven and earth do this? What kind of existence is heaven and earth?" Elder Jin Jue showed a confused look on his face.

Sun Yi waved his hand: "The heaven and earth are too far away from us. With our current cultivation level, we can't even reach that level. The most urgent task is to solve the problem of the lower-grade spiritual root disciples breaking through the realm."

"Master, have you found a solution?" Li Tai looked at Sun Yi with anticipation.

Sun Yi's lips curled up slightly: "The method is very simple, I have already thought of it, but it is difficult to achieve it."

"What? Master, you have found a solution? Is that true?" Elder Jin Jue widened his eyes and looked at Sun Yi excitedly.

The other people in the training room also looked at Sun Yi in shock.

Sun Yi swept his eyes over everyone and spoke again: "Now that we know where the problem lies, we just need to find a targeted solution."

"But although there is a way, it is difficult to do it."

"In fact, the difficulty in breaking through the realm is the power of heavenly punishment generated by breaking the shackles. This power of heavenly punishment will act on both the body and the soul at the same time. As long as our body and soul are strong enough to withstand this power of heavenly punishment, we can easily break through the realm without relying on the foundation-building pill."

"I've observed that the power of heavenly punishment endured by cultivators with low-grade spiritual roots is very strong. However, with my current physical strength, even without using the Foundation Establishment Pill, my physical body can withstand this power of heavenly punishment."

After saying that, Sun Yi immediately performed the Wind and Thunder Step, appeared at the edge of the training room in a flash, and then punched the wall hard.

boom!

With a loud bang, the training room shook slightly. A deep fist mark appeared on the wall where Sun Yi punched, and there were cracks around the fist mark.

"This... this is Wind and Thunder Step!"

The five Jindan-stage elders were all stunned. Of course, they recognized that the footwork displayed by Sun Yi was the most advanced Fenglei Step in Qingyun Sect.
