After the cultivation of "Yu Ye is like a knife", ye Ziheng then began to cultivate the third stage of "Zhu Shen Shu", which is like iron.

In fact, this realm is simple. It seems that it is not so simple. It is not very difficult to say it is difficult.

The so-called "resisting water is like iron" is to let people control water and make the strength of water reach the same level as iron.

The most difficult thing in this realm is that after a ray of magic power is injected into it, not all water can be mobilized, but only about one tenth of water can be mobilized.

In fact, it's very simple to solve this problem, as long as several magic powers are injected, but if this is the case, water defense is like iron, there is no significance for him.

There are two cultivation points to control water like iron. One is to control part of the water with less power, and then use this part of the water to control other parts of the water.

The second part is to change the softness of water into the hardness of iron, which is extremely difficult.

In the first part, ye Ziheng failed several times and summed up his experience. Then he could easily control the water and make them change all kinds of forms.

What's really difficult is the second part, turning soft into hard.

Ye Ziheng spent more than one hour not to understand what this really means. How to turn soft into hard? How to turn soft into hard?

Seeing ye Ziheng's incomprehensible solution, Chu Tian asks for a moment and finally decides to remind ye Ziheng.

"The extremes of things must be reversed. The softness is the most rigid, and the hardness is the most flexible."

Chu Tianqiu's words are like a flash of fire in a gasoline barrel, which immediately ignites ye Ziheng's brain filled thoughts. In a flash, he understands what to do. He defends the water with one hand and the sword with the other hand. Then he attacks the water with the sword in his hand. The second before the water is attacked, he lets the divine force play a role, makes the water suddenly lift, and then instantly withdraws the divine force.

"Bang!"

A crisp sound, the sword hit the water heavily, but the next second, he did not penetrate the water, but became several pieces of debris, slowly falling.

See this scene, ye Ziheng that call a joy extremely, looking at Chu Tianqiu's face is full of gratitude.

But Chu Tianqiu saw this scene, but suddenly felt some angina.

This is the most difficult part of the art of divination. In order to reach this level, he tried many times. His father also told him the same words, even more straightforward than this, but it took him more than a year to really understand the truth.

While Chu Tianqiu was still recalling the past, ye Ziheng once again spread the news.

"It's a success!"

When Chu Tianqiu heard this, he looked at ye Ziheng and almost didn't get a mouthful of old blood.

Ye Ziheng, even in his recollection of the past few seconds, the fourth stage of the "iron like water" to cultivate successfully!

Although the principle of "iron is like water" in the fourth stage is similar to that of "iron is like water" in the third stage, there are still many subtle differences in control methods. It took him three months to learn this stage at first, but why did ye Ziheng learn it in a few seconds! It's not fair!

Suddenly in this moment, Chu Tianqiu's mind came up with an idea. He suddenly felt that the idea of the demon lord, that everyone is equal and has the same talent, is a very good idea.

Of course, it's just self talk.
