Once upon a time, the plateau where the Burial Soul Hill was located was a flat steppe, but the great battle caused a huge earthquake, and the main plateau was turned upside down by violent geological movements.

A huge mountain rises from the ground, while the other side is sunken down, creating an extremely noticeable fault. This fault completely splits the river that originally flowed through the plateau into two sections, forming a huge waterfall.

The waterfall is hundreds of meters high, and the rocks that have been downstream of the cliff face have been washed away by the impact over the years.

A young man just stood in the rushing waterfall, using his flesh and blood to carry the impact of the falling waterfall, he could hardly even straighten his back, but he still held on silently.

Not only that, but his posture is very strange, the whole person is almost upside down on the rock, supporting the ground with his right hand, his left foot and head against the ground at the same time, and only his right foot is standing up high and pointing to the sky.

It's been a full month since I first came here, and I can't even stand on my feet at first, and now I can barely maintain this movement for ten minutes, which is exchanged for countless times when the ground man is knocked on his back by the tremendous force of the impact.

Although there was no improvement in the realm, Lin Xi vaguely felt that not only the strength of his muscles had increased, but even his control over his muscles had reached a great improvement.

"Hikana, how long am I going to do this stupid thing?" Lin Xi spit out a large mouthful of water poured into his throat, and asked with a painful face, this feeling was almost like the whole person was about to fall apart.

"Do you know how many people want to get this set of secrets and can't get it, and you say it's stupid?" Hikana said angrily.

When the Soul Sword Venerable was still alive, he traveled a wide range of universes, and had seen many strange races, each of which had their own talents, and some of them could not even hurt even if they did not have any combat power.

There is a race among them, they are the same as the earthlings are indigenous planets that have not yet been discovered by the cosmic federal government, there is no technology here, they live a primitive life, their physique is almost not too different from the earthlings, but they can knock over behemoths like elephants with one punch.

This race has no cultivation methods, let alone special abilities, but they are born with a huge advantage, and every born clansman can exert 100% of their full strength potential, and some can even break that upper limit.

Of course, the theoretical upper limit is determined by the strength of the body's muscles and bones, and if the upper limit is broken, it will inevitably cause some damage to the body.

This peculiar phenomenon soon caught the attention of the Soul Sword Venerable, who, in order to unravel the secret, quietly devoured an indigenous person through the secret technique he had stumbled upon and discovered the secret of their body.

All the intelligent races in the universe may be very different in size and appearance, but they are very similar in some subtle structures, except for some extremely special life forms, such as intelligent life like Hikana, most of the basic units of other living beings are cells.

After a period of research, the Soul Sword Venerable found that the people of this race were very different from other races in terms of muscles.

For example, human beings have many acupuncture points on the human body, acupuncture points are the convergence points of blood vessels and nerve endings, and are a very important part of the human body.

But the indigenous race is different, all the absences in their bodies are almost connected into a dense network of information, like a thread connecting every part of the body, so as to achieve a similar effect to complete control of the body.

After a long period of research, the Soul Sword Venerable finally found a way to get through all the acupuncture points, and created a set of body refining secret techniques, as long as all the acupuncture points on the body are penetrated one by one according to this method, the efficiency of the body's power can be increased to more than 90%!

Although it sounds very difficult, there is no threshold for this secret art, even an ordinary person can still learn it, but there is a condition, that is, you must have a strong enough physique.

This physical criterion is not a matter of death, but is judged by one's strength. Because with the improvement of physical fitness, the difficulty of opening acupuncture points will also increase correspondingly, so you need to have a stronger physique to withstand the impact of opening acupuncture points.

If the strength of the body is not enough, then when cultivating, it is very likely that a certain part of the human body will be too brittle to withstand that force and collapse, and it will be seriously injured, disabled or even killed, so Lin Xi was forced by Hikana to start a hellish training in the waterfall.

In addition to eating and sleeping, he spent more than 15 hours a day in the waterfall for a month, and still remembers the first time he stood up, the powerful impact directly knocked him out of the mouth and spat blood, and it took a long time to barely stand up.

"Well, the right hand and left leg should be about the same, then change to the left arm and right leg, continue to keep it for a month, and then you can try to open up some of the acupuncture points." Hikana said as if he were educating his apprentice.

"What? Another month? Lin Xi was already a little on the verge of collapse, and he was allowed to rest almost every day after being exhausted, but it was only half of it.

"Okay, I don't care if you want to start now, but if you're not strong enough to get disabled, don't blame me."

Lin Xi closed his mouth in amusement, although a month was difficult, but it was better than being disabled, he was only less than twenty years old, and he didn't want to lose his arms and legs at a young age.

......

Another month passed quietly, Lin Xi's originally slightly thin body became stronger under the exercise of the waterfall, and it seemed that he had sharpened a lot of his sharpness, and at this moment he was sitting in the center of the waterfall, motionless like a solid boulder.

Just as Hikana said, every part of his body was fully exercised in this strange position, even the neck and joints, which were not easy to exercise, became much stronger than before.

"Well, Hikana, I should be able to start now, right?" Lin Xi walked out of the waterfall steadily, not even a hint of shaking.

"Well, it's very good, even if the current body is cut with a human-level inferior weapon, it will only suffer some skin trauma at most, which should be enough!" "But I warn you that you must not stop in the process of opening the acupuncture points, otherwise it will be as dangerous as failure." ”

Lin Xi nodded, his will had already been tempered to be extremely tough, as long as his body could withstand it, then there was absolutely nothing he couldn't hold onto.

In order not to be disturbed by others, Lin Xi found a cave left by his predecessors here, he blocked the entrance with branches and stones, and then lit a lamp in the cave.

"This is the 365 Zhou Tianxing map left by your teacher!" Shikana turned into a ball of light and jumped out of Lin Xi's body, emitting a dazzling light from it, projecting 365 paintings on the stone walls of the cave.

In each picture was the image of a person, they posed all kinds of strange movements, and some even curled up their entire bodies together, forming a strange bend, Lin Xi doubted whether he could make such movements.

"These 365 figures, each of which represents a method of opening up an acupuncture point, as long as you can make all of them and run the ability in a certain way, until it is completely dredged, then you can almost exert the maximum strength of your body." Hikana explained.

"It's as simple as that?" Lin Xi was a little incredulous.

"Simple? Do you know that it took the master nearly 2 million years to study these patterns, and every movement must not deviate in the slightest, without my help, no one can successfully practice! Hikana said unconvinced.
