Metal wood, not an official name, refers to some sharp grass and trees that are comparable in hardness to metal.

When Mr. Hong taught him the art of swordsmanship, he gave him a Book of Hundred Flowers Sword Manual, which contained records of many famous swords in the world.

Among them are some rare swords, which are polished from natural vegetation.

There are many plants and trees that can be turned into swords, and the most famous ones are ancient architectural trees.

The source of the sword in my hand cannot be traced.

However, its color is dull and has no aura. No matter how powerful it is, it is probably just a useless sword.

When grass and trees become swords, the most important thing is the natural Taoist charm and aura. Without special maintenance. As time goes by, the aura disappears and the Taoist charm does not exist, it is not as good as an ordinary sword.

But Lin Yun was still very happy, at least the sword was not broken.

It takes good care of itself and is barely enough.

Sheathing the sword, Lin Yun took out the Pure Yang Kung Fu and said with some anticipation: "It's time to practice inner strength."

If you don't cultivate your inner strength, there will never be a way out. Only the third level of martial arts can be regarded as a true warrior.

Cross your legs and close your eyes.

After sensing the internal energy in his body, Lin Yun used Pure Yang Kung to carefully operate the internal energy in his body.

At first, I was not very skilled.

The energy is rushing around in the body and is difficult to control, like a loach.

By the time I mastered it, it was already dark.

Accompanied by the starlight in the sky, Lin Yun's expectation has reached its peak and he can finally successfully operate the Pure Yang Kung Fu.

With his mind sinking and Pure Yang Kung running, Lin Yun entered some mysterious state.

As the internal energy circulated in the body, he could actually see the internal organs clearly, which was amazing.

Look inside!

After practicing the martial arts at the third level, you can look inside the body and the five internal organs, and truly embark on the path of a warrior.

However, Lin Yun, who was immersed in the practice of Kung Fu, did not notice it.

In the mysterious space above the Dantian in the body, an ancient broken sword exists alone, with nine chains wrapped around the hilt spreading in the darkness.

When it was running the Pure Yang Kung Fu, a little spiritual light fell on the broken sword, causing ripples.

As the spiritual light fell, the end of the chain stirred in the darkness.
