Although I don't know that the ninja method has developed to various levels now, but the power of the undersea city is so strong, it is obvious that its combat power is very prominent.

Li Chen comprehended in his heart, read through the mystery of the origin of the ninja method, and nodded again and again, it is not easy for Xu Shijie to have such an ability, of course, Li Chen also understands that kind of Tao is incredible, and has great potential.

Xu Shijie also comprehended the forbearance method from an ancient book, which he got by chance in the dangerous land of the fairy world, the text on it was profound and difficult to understand, and he didn't have the time to study it in the fairy world.

After coming to the earth, I had nothing to do, so I began to specialize in research for a few years, but I didn't expect to realize some ways and develop a set of forbearance methods, which is completely different from the fairy way, and it can be said that each has its own wonders.

Of course, that book was also passed down by Li Chen, and the content of the book was not made public by Xu Shijie, but only some mental methods for absorbing energy for meditation were disclosed.

With this mental ninjutsu, it has been carried forward by later generations, and a variety of practical ninjutsu have been derived.

And those tailed beasts were caused by the chaos in the space caused by the mantra recorded in Xu Shijie's cultivation book, and the influx of some monsters from different dimensions.

The power of this book lies in this, and after that, Xu Shijie will not dare to cultivate anymore, and he will not be able to escape in case of chaos in the space.

Li Chen gradually penetrated into the depths of the Yuan Shen, observing the powerful book, the book gradually had an outline, and the title of the book appeared, a "empty" word, this word appeared suddenly, the text Li Chen couldn't recognize it, but he was sure that this was an empty word, as if there was a power to make him believe that this was an "empty" word.

Li Chen looked at the title of the book and was shocked, the breath of ancient vicissitudes slowly flowed on the book cover, and waves of qi rushed towards him.

"It's shocking! It's like a small world. Li Chen was surprised.

As far as Li Chen knew, Xu Shijie also got the book by chance, when the Immortal Emperor fought for the godhead, resulting in the space being shattered, and a large area of spatial turbulence appeared.

At that moment, a cyan light flew out from the spatial turbulence and shot directly at his front door, Xu Shijie had no choice but to subconsciously block it with his hand.

After getting out of danger, Xu Shijie stretched out his hand to look at the things in his hand, only to see a cyan mark on his palm, which could no longer be scrubbed.

In the next few days, Xu Shijie had a headache, and then the spiritual power of the Yuan began to deplete, and he slept when he was tired every day, and the immortal doctor couldn't diagnose what the problem was.

In this way, Xu Shijie endured for ten years before he slowly improved, and the cyan mark on his hand disappeared into invisibility, which was very weird, and since then some mysterious words appeared in his mind, and gradually Xu Shijie put those words together and made up a strange book.

It is very strange that this book was formed suddenly, his Yuan Ling is like a space containing this book, if he is allowed to write it, he can't write it, and no one else can understand it, so he has to ponder and study it himself, so Xu Shijie was distressed for a while.

Before this, he was rescued by Li Chen, and gradually became familiar with Li Chen, knowing that Li Chen's qualifications were extraordinary, maybe only Li Chen could comprehend this book, so he crossed into Li Chen's Yuan Shen along with the inheritance.

Li Chen pondered carefully and scolded: "This grandson, he has a headache for ten years, and I have a headache for a few years!" The more Li Chen thought about it, the more scared he became.

It was the first time he had heard of such a strange thing, and now that such a book appeared in his Yuan Shen, how could he be at ease!

But the facts are in front of him, Li Chen has no choice, with his Yuan Shen is more than a little stronger than Xu Shijie's Yuan Spirit, isn't it very simple to understand the mystery in this book?

Li Chen no longer hesitated, as soon as the Yuan Shen moved, the book in the Yuan Shen was clearly displayed in front of his eyes, and it was so laborious and weird to turn a page gently.

With the movement of his eyes, the strange words in this book were also written down by Li Chen, and those words were like a strange rune spell mark, which could not be described and understood by words, but had to look at its shape to understand its meaning.

It was at this time that Li Chen's eyes began to change, but he himself knew nothing.

The original black pupils began to turn red, and this book was only 99 pages in Li Chen's view, but he read very slowly, and turning the paper was as difficult as moving a mountain.

And as the pages flipped Li Chen's eyes became more and more red, as red as blood, and black runes began to appear in his pupils, which was completely a copy of the writing wheel, from one hook jade to two hooks and then to three hooks.

The three-hook jade writing wheel eye was perfectly formed, and Li Chen suddenly came to his senses, his heartbeat accelerated, his breathing accelerated, his body trembled, and he didn't know what happened just now, he only knew that there was something more in the Yuan Shen.

And his consciousness was filled with a lot of red energy, and these energies were mixed with black rune spells, this information was huge and complex, and Li Chen's entire mind was occupied, which could be regarded as completely confused.

"What a special power! This is the Bloodline Limit? Li Chen was very excited, he had never thought that he would have such a day since he was a Naruto fan.

The next strange thing didn't end, and in just nine pages of the book, Li Chen's eyes underwent a strange transformation, mutating into a writing wheel.

After that, Li Chen turned the tenth page again, this time it was not red words, but green, just like the first nine pages, the words inside were even more esoteric and complex, and the green characters were like saplings that continued to take root and sprout, with infinite vitality.

Li Chen observed carefully, and streams of green energy continued to spread from the book, until they covered Li Chen's entire Yuan Shen, Li Chen's mind was completely immersed in it, and the huge life force continued to pour into his body, and even rushed out.

At this moment, Li Chen's physical body changed, his whole body emitted green light, his body began to grow bright green shoots, and every cell and hair gushed out infinite life force.

These life forces were entangled and combined with each other, enveloping Li Chen in just a few minutes, until they turned into a huge tree.

The space is so abnormal that it has already alarmed the city lord and other elders, Mu Ling has been guarding the gate of the Shadow Sect's palace, talking to the actor emperor.

As a ninja, Mu Ling had already felt the abnormalities in the palace, and the huge vitality was even about to break out.

"What's going on?" Mu Ling was shocked, and he didn't care about chatting with the actor, so he pushed the door directly and rushed in.

The door opened, and countless green and even almost materialized life energy gushed out, merging with the sea water, the sea water instantly turned green, and the fish in the water absorbed this energy actually developed rapidly, from small fish to big fish, swimming happily in the sea.
