In addition to studying the changes in the nature of chakra on a daily basis, Zong Ju also went to the Wet Bone Forest from time to time to learn immortal arts.

However, what he had learned was not the unique immortal art of the Wet Bone Forest.

It's just a way to sense natural energy, and to combine natural energy with one's own chakra.

Zong Ju didn't want to make himself bloated and sticky slug characteristics because of his cultivation of immortal arts.

There are actually several kinds of immortal arts circulating in this world.

The immortal arts inherited by the three holy places are only immortal arts that are suitable for their own racial characteristics.

If human beings want to forcibly learn the immortal arts of these holy places, it will not only be very difficult, but also make themselves take on the characteristics of those races.

For human beings, the best thing is still suitable for human beings' own immortal system.

But unfortunately, there is no such inheritance among human beings.

In fact, there are some ancient Buddhist temples where immortal arts are spread.

For example, the Temple of Fire in the Land of Fire.

But those immortal systems are very superficial, far less mature than the three holy lands.

"The Six Dao Immortals back then learned the immortal art from the Toad Pill."

"However, after he learned the immortal arts, there were no obvious toad characteristics on his body!"

"This shows that it is very likely that he has made improvements to the immortal arts of the toad clan and developed an immortal technique suitable for his big barrel wood clan!"

"The six Dao immortals are extremely intelligent, and it is not surprising that they can make such improvements, so can I also try to improve the immortal arts and develop immortal arts suitable for human beings?"

Sitting in the wet bone forest, such a thought rose in Zong Ju's heart.

Developing a system of immortal arts suitable for humans was something he had been thinking about for a long time.

This can be very difficult for others.

Because, the natural energy is extremely violent, and the slightest carelessness can cause serious damage to the body.

Therefore, one must be cautious and look for those cultivation methods that are already mature.

But Zong Ju has a strong advantage.

He is not afraid of the damage that natural energy can cause to the body because his healing power is amazing.

Moreover, if the natural energy gets out of control, he can use the Divine Tree to absorb it immediately.

Experimenting with your own body is crazy for other ninjas.

But for Zong Ju, it just happened to play to his advantages.

"Orochimaru is also studying immortal arts, but his method is too slow!"

"He can only do experiments on others step by step, collect data little by little, and constantly make adjustments!"

"It could take him a month, or even a year, to make a little progress!"

"I'm different, I directly use my own body to do experiments, I can get the most intuitive feeling, I can get first-hand data!"

"And I don't have to be careful to control the experimental dose!"

In his heart, Zong Ju carefully analyzed his advantages.

Although, he is not a research-oriented talent like Orochimaru, and he doesn't know anything about human experiments and biomedicine.

However, he has an advantage that Orochimaru can never match.

His results in one night may exceed a year of research by Orochimaru.

"The difference between the immortal arts of different systems should be mainly caused by the physiological structure and the matching ratio of natural energy to chakra!"

"In that case, then I'll adjust the ratio of natural energy and chakra little by little!"

"Let's try it first by adding Sancheng natural energy to the chakra according to the experience in the original book!"

In the Wet Bone Forest, Zong Ju sat in a place with strong natural energy, his expression was very serene.

"Bang!"

"Boom!"

......

All sorts of explosions rang out in his body.

From time to time, a big bag bulged up on his body, and then, with a bang, it exploded.

Flesh and blood flying, and the scene was extremely miserable.

But with the blessing of Zongju's amazing healing ability, this injury can be recovered immediately.

After each injury, Zongju would further adjust the ratio of chakra to natural energy.

"The immortal art of the Wet Bone Forest is that the natural energy accounts for forty percent, the physical energy accounts for forty percent, and the spiritual energy accounts for two layers, thus forming a balance!"

"The principle is nothing more than using physical energy and spiritual energy to suppress the violent natural energy!"

"Slug creatures seem to be soft, but in fact their bodies are very energetic!"

"Therefore, in the immortal arts of their race, the proportion of physical energy is more than that of spiritual energy!"

"In the original work, the immortal art of the toad clan exists in the form of natural energy, physical energy, and spiritual energy 1:1:1."

"Is this because the toad clan's physical energy is weak, so the proportion of natural energy is reduced and the proportion of spiritual energy is increased to reconcile?"

While practicing by himself, Zong Ju did not forget to ask the slug immortals for advice.

This immortal, who had lived for thousands of years, was very interested in what Zong Ju was doing now.

Not only did he answer all questions about Zongju's inquiry, but also put forward a lot of constructive suggestions.

From her, Zong Ju learned many secrets about the immortal arts of the three holy lands.

Generally speaking, in the composition ratio of the immortal chakra, the higher the proportion of natural energy, the more powerful it is.

Therefore, the immortal power of the slug clan is probably stronger than that of the toad clan.

At the beginning, the immortal art that could be cultivated into the Wet Bone Forest between the Thousand Hand Pillars was also because of the extremely powerful energy of his body.

"For me, it is needless to say that the physical energy is strong, and the spiritual energy, because I am a traverser, is also stronger!"

"In this way, the previous idea of adjusting the proportion of natural energy to less than 40% is wrong, I should try to adjust it higher!"

Zongju changed his thinking and began to increase the proportion of natural energy.

His physical and spiritual energies were extremely strong, and even if the proportion was low, it was enough to suppress the natural energy with a higher proportion.

When Zong Ju adjusted the ratio of natural energy to forty percent, the various explosions that occurred on his body were even more amazing.

The more natural energy contains, the more the rampaging energy will hurt him.

"Although the injury is getting worse and worse, I can feel that my physical energy and mental energy can still completely suppress the natural energy!"

"It is precisely because of this one-sided suppression that natural energy has repeatedly gone violent!"

"It seems that even if forty percent is still low, we have to continue to raise it!"

One night has passed, and Zong Ju has been using his body to explore the immortal art that suits him.

Such frequent explosions still occur in the body, and if it were someone else, I don't know how many times I would have died.

But Zong Ju was still unscathed, only his clothes became tattered.

However, while physical injuries heal, the mental torment of the constant onset of pain is not immediately eliminated.

The next day, Zong Ju left the Wet Bone Forest with a pale face, returned to his home and fell asleep!
