Tongtianmu has a very big background.

In ancient times, there was a sacred tree between heaven and earth, called Jianmu, which could communicate with heaven and earth. Jianmu later collapsed and disappeared between heaven and earth for some inexplicable reasons.

But at that time, the three immortal ancestors of the Shangsanmen had already attained enlightenment, so they each picked up a branch from the ruins of Jianmu and returned.

And Tongtian Wood is the branch of Jianmu picked up by Daluo.

Jianmu is the spiritual root of heaven and earth, and Tongtian wood can naturally be regarded as a strange species. In addition, it was planted by the ancestor of the immortals and was taught immortal methods. In the past four hundred years, this Tongtian wood has accumulated almost endless vitality.

Therefore, when practicing in its tree hole, Li Yun did not have to worry about the issue of vital energy. He deliberately closed his eyes and used his mind to attract the vital energy in his body without restraint, incorporated these vital energy into the dantian, refined them into true energy, and then condensed these true energy continuously.

At the same time, his soul was constantly absorbing the purple air in his eyebrows.

Originally, the true essence cultivated by the Hunyuan Yi Qi Jing was almost invisible, but now, as Li Yun absorbed the purple qi, his true essence had already brought some faint purple color.

These purple colors will always be with him. If nothing unexpected happens, if Li Yun practices Yuan Dan in the future, he will definitely be a purple Yuan Dan.

While being able to absorb vital energy without restraint, the Hunyuan Qi Meridian showed extremely abnormal energy condensation ability. Li Yun sat on the cushion, like a whale absorbing water, and introduced all the nearby vital energy into his dantian.

Because Li Yun's soul now has some ability to control the vital energy, when these vital energy enter Li Yun's dantian, it is tempered into Hunyuan Yiqi and merged into Li Yun's original vital energy.

His cultivation level rose almost like a rocket.

In just three days, the true energy in Li Yun's dantian increased by more than 10%.

This progress is very terrible.

If according to this progress, as long as Li Yun stays here to practice, he can complete the realm of true essence and reach the threshold of the realm of Yuandan!

But unfortunately, his speed of practice is not completely unrestricted.

Because after Li Yun increased his true energy, it would be more and more difficult to condense the true energy. Moreover, because he absorbed the vital energy too quickly, it was difficult to control the vital energy to continue to condense with his current spiritual power.

If this continues, he will not be able to continue to condense his true essence, nor will he see the gate to the Yuandan realm.

Finally, after five days of practice, Li Yun slowly opened his eyes.

At this time, after five days of practice, his spirit that had been exhausted in the library had completely recovered and his whole body became full of energy. However, because the intensity of his mental power was not strong enough, Li Yun now could no longer consolidate the true energy in his dantian.

"It seems that I need to practice a method to train my spirit."

Li Yun glanced at Feng Tongzi who was still practicing beside him and murmured: "As long as my spirit is strong enough, I can control more and more vitality. If I now have the mental power of the Earth Immortal Realm, I am afraid that it will only take one or two days to cultivate the Yuan Dan..."

That being said, but the magical methods that can train mental power are too rare.

Li Yun sat on the cushion and pondered for a moment. Then he fumbled in the mustard bag for a while, and finally found a piece of the sword tip.

There were originally eleven sword marks on the tip of this sword, but the last time Li Yun was inherited from one of the sword marks, only ten sword marks were left.

To be honest, Li Yun didn't want to touch the inheritance left by his uncle.

Because the process is so painful.

Just the first sword intent broke the emptiness, Li Yun fainted several times, and in the process of accepting the inheritance later, Li Yun felt like he was killed again and again.

From accepting the Breaking Void Sword Intent to now, Li Yun has been "killed" almost hundreds of times.

But it has to be admitted that this kind of inheritance is very useful for training spiritual strength. Now, after receiving so many temperings, Li Yun's spiritual strength is definitely the top in the realm of true essence.

Li Yun looked at the faint golden blood on the tip of the sword. After taking a deep breath, he stretched out his finger and gently stroked the tip of the sword. The tip of the sword cut Li Yun's finger, and the red blood was applied to the tip of the sword.

The red blood blended with the golden blood, and the second sword mark on the tip of the sword began to appear.

Then, the light shone brightly.

The second sword intent slashed out from the sword mark and slashed towards Li Yun's eyebrows again.

This sword light is extremely sharp.

Almost in an instant of excitement, he slashed into Li Yun's eyebrows. Then, the purple little man sitting upright in his eyebrows was cut off by a sword light, and his head rolled down from his neck!

The head rolled onto the ground, staring with big eyes, and looked disbelief.

Immediately afterwards, the head melted into vitality and merged with the body that had lost its head. Then the purple villain slowly grew a head!

This purple villain now represents Li Yun’s soul!

The moment the purple villain recovered, Li Yun from the real world opened his eyes. He was already sweating all over and subconsciously threw the broken sword in his hand aside.

"Damn..."

Li Yun almost collapsed on the ground, sweating all over his head.

This time the sword light is very different from the first Breaking Void Sword Intent!

The first time the sword intent of the Breaking Void was targeted at Li Yun's spirit, and it only cut off his spiritual head. However, the spirit had no shape. No matter how many times he died, it would not affect him. At most it would only give Li Yun a headache!

But this time it's different!

This time the sword light really cut off Li Yun's soul's head!

In other words, if Li Yun had not refined this strange unity of divine essence, or if his soul still existed, Li Yun would definitely die if he continued this sword!

His Royal Highness took several deep breaths before he came to his senses. He stared at the broken sword that he had thrown aside, his eyes filled with surprise.

"Is this... the inheritance left by my uncle..."

Li Yun wiped the sweat from his forehead, and his eyes were filled with deep horror: "It almost killed me, and uncle Li Mo could not kill me..."

His expression was a little horrified.

Even this kind of sword technique is not only aimed at the soul, but also at the soul!
