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

After the battle, Sun Yi continued to rest, and after he had rested well, he would start a new round of battle.

In the next ten days, Sun Yi fought with the Flying Tigers continuously, and every battle made Sun Yi feel very refreshed.

It used to take an hour to deal with this flying tiger, but after this period of training, Sun Yi's strength increased rapidly, and it became much easier to deal with the flying tiger. It only took one tenth of the time to easily deal with the flying tiger.

Sun Yi was very satisfied with the improvement of his strength, but he did not rush to the second floor to continue the challenge. Instead, he left the battle tower and quickly returned to the training room in the Sutra Library.

The time to hone my strength is almost over, and there are more important things to do next.

With a wave of his right hand, a monster corpse suddenly appeared on the ground in front of him. It was the corpse of the Miro beast, a strange monster that could open up a new dantian in its body.

During the battle against the Flying Tiger in the battle tower, Sun Yi deeply felt the insufficiency of his own true energy.

Sun Yi felt like he was a machine, his dantian was the fuel tank, and his true qi was the fuel. Now his endurance was insufficient. The solution was to replace it with better fuel or expand the fuel tank.

He has tried to improve the quality of his true qi, including switching to advanced Five Elements Kung Fu and using the Soul Tempering Pill. There is no other way at the moment. As for expanding his dantian, he has no idea. The most likely way to increase his endurance is to open up a new dantian. He already has a direction for this path, and it is the easiest to achieve.

So he decided to do some research first. If he could really open up another dantian in his body, his endurance and combat strength would be greatly improved.

Next, Sun Yi began to dissect the body of the Miro beast. He was very careful, fearing that there would be any mistakes, and concentrated on studying the body of the Miro beast.

As time went by, Qingyun Sect did not encounter any problems even though it lost its leader Sun Yi. The sect's strength was increasing at a rocket speed.

A month passes in the blink of an eye. For a monk, a month is just a blink of an eye.

At this time in the training room, Sun Yi was still studying the corpse of the Miro beast, but now the Miro beast had been broken down into countless small pieces.

At this time, Sun Yi was concentrating on studying a ball of white material in his hand. He had been studying this thing for more than ten days.

Suddenly, two rays of light burst out from Sun Yi's eyes, and an expression of ecstasy suddenly appeared on his face.

"Hahahaha, I see! So that's how it is! This is why Miromon can open up new Dantian in his body. Now I can open up new Dantian in my body too!"

Sun Yi is a professional in research. After a month of crazy research, he finally figured out the secret of the Miro beast's body and also found a way to open up a new Dantian in his own body.

After figuring out a solution, Sun Yi immediately asked someone to call Elder Ye Luo to his training room.

Elder Ye Luo hurried to the training room where Sun Yi was. As soon as he came in, he saw that Sun Yi's training room was in a mess. The corpse of a monster had been decomposed beyond recognition by Sun Yi.

At this moment, Sun Yi was staring at a white ball the size of a human head in his hand and grinning foolishly.

"Master, what do you want to talk to me about?" Ye Luo asked hurriedly.

Only then did Sun Yi realize that Ye Luo had come in, and he quickly reached out to call Ye Luo over.

"Elder Ye Luo, please come and help me refine this thing."

Elder Ye Luo came to Sun Yi, looked at the white ball in Sun Yi's hand, and asked with a puzzled look on his face: "What is this?"

Sun Yi excitedly explained to Elder Ye Luo: "This is the secret of the Miro beast. It is precisely because the Miro beast can produce this substance that they can re-open the Dantian in their internal organs."

"What? Is this true?" Elder Ye Luo exclaimed.

"Of course it's true. How could I lie to you? Hurry up and help me refine the stuff. I need to try to see if I can open up a new Dantian in my body."

Sun Yi can't wait to try it now, but the substance in the Miro beast's body needs to be refined and purified before it will be safer.

Ye Luo was shocked when he heard this and quickly persuaded him: "Master, it's too risky for you to do this. You should find someone else to try. After all, opening up the Dantian in the body is too dangerous, and no one has succeeded before."

Sun Yi waved his hand and said, "Don't worry, I've studied it many times. Theoretically, there won't be any problems. Besides, there are only so many substances in the body of this Miro beast, only enough for one person to open up the Dantian in his body."

"Don't worry, when I open up my Dantian, I'll let you stay by my side to protect me. If you encounter any danger, don't worry."

Seeing Sun Yi's firm attitude, Elder Ye Luo could only nod helplessly, and then he took action to refine the white sphere.

I saw a sphere the size of a human head being continuously refined in the Dan fire controlled by Elder Ye Luo. Various impurities were burned and the volume of the sphere continued to shrink.

It took Elder Ye Luo a whole day to refine this thing to perfection.

At this time, the ball that was the size of a head had shrunk to the size of a ping-pong ball. Sun Yi held it in his hand. The ball was as smooth and soft as jelly, and it glowed with a white and soft light. It even emitted a faint fragrance that smelled very comfortable.

Looking at the white ball in his hand, Sun Yi called out to Elder Ye Luo impatiently: "Elder Ye Luo, please stay by my side and protect me. I will start trying now."

Elder Ye Luo still looked at Sun Yi with some concern: "Isn't it too risky? Otherwise, let's wait until the ancestor comes back before trying it again."

Elder Ye Luo was still worried that he could not protect Sun Yi, and was afraid that something might happen to Sun Yi.

Sun Yi waved his hand with a confident expression: "Don't worry, there won't be any problems. I have thoroughly studied the theory. Now all that's left is practice."

"let us start."

Sun Yi didn't care whether Elder Ye Luo agreed or not. He just sat cross-legged on the training platform next to him and put the ball in his hand directly into his mouth.

The true energy in the body wrapped the ball and moved it slowly. After a while, the ball was moved to the right lung lobe.

After detailed research, Sun Yi concluded that if one wanted to open up a new Dantian, they could only do so in the internal organs. He chose to open up a new Dantian in his right lung because he had two lungs. If there was a problem with the lung that was used to open up the Dantian, he could still use the other lung temporarily.

The right lung is chosen to open the Dantian because the left lung is close to the heart, and it would be bad if there was a problem that affected the heart.

After moving the sphere to the lungs, Sun Yi began to wrap his right lung and the sphere with his true qi, and forced a drop of his own blood to merge into the sphere. Then he used his true qi to slowly refine it, so that the sphere and his breath gradually became the same. This process took a full five days.

Five days later, the breath of the right lung was exactly the same as that of the white sphere. The breath had merged into one, and there was a feeling of blood connection. Sun Yi then took a deep breath and suddenly injected his true energy into the sphere frantically.

It was unknown how long it had been, but Sun Yi suddenly caused the true energy in the white ball to explode, and at the same time he controlled another part of the true energy to wrap around his right lung.

boom!

Sun Yi's right lung seemed to explode. A violent force appeared in his right lung, almost tearing it apart. Fortunately, his body had been strengthened and his lungs had been strengthened many times, otherwise he would not be able to withstand this wave of impact.

Severe pain came from his right lung, making Sun Yi break out in a cold sweat. Sun Yi had not expected that opening up his Dantian would be so painful. Now there was no way out and he could only endure it.

The true qi wrapped around the right lung, suppressing the riot inside. At this time, Sun Yi's right lung was undergoing earth-shaking changes, and these changes were very mysterious.

After five hours, the pain disappeared. Sun Yi checked his right lung and found a new dantian in it.

"Hahaha, I succeeded!" Sun Yi couldn't help but cheer and clenched his fists. He knew very well what opening up a new Dantian meant to him and how much significance it had to the entire Qingyun Sect.
