Tianwu Academy's contacts, in the iron forest in the back mountain, Chen Fan is constantly fighting against a big tree.

At this moment, it has been three days since he entered the academy, but the task of building a small wooden house that Mu Yunhai explained at the beginning was still not achieved.

Not only that, after three days, Chen Fan didn't even interrupt a tree!

"drink!"

With a stubborn color on his face, he bombarded the iron tree with a fist, and the gust of wind from his fist made the surrounding leaves sway and screamed.

With the explosion of 6,000 catties, even an elephant can be easily penetrated by Chen Fan's punch, but seeing the iron tree, it still doesn't move at all, and it didn't even shake!

Taking a breath, Chen Fan wiped off the sweat from his forehead and sat cross-legged under the tree to recover his luck. This is something he has been repeating for three days.

Chen Fan is a very proud person in his bones. He does not allow himself to be unable to interrupt a tree, even if it is not an ordinary tree.

So he didn't eat or drink for three days and didn't sleep. He had been competing with the iron tree in front of him. He recovered on the spot after he had consumed his internal breath, and continued to repeatedly punch his punches.

It was not that he had never thought of using the Dugu sword to cut the iron tree, but after thinking about it, he did not choose to do so.

If you just face a tree and use the strongest assassin, then this martial art is not worth it!

When the recovery was over, Chen Fan began to punch again, but he didn't notice, and Mu Yunhai had been observing him not far away.

It stands to reason that even if Chen Fan's realm is not too strong, it cannot be discovered by secret observation, but for some reason, Mu Yunhai has never exuded the slightest breath, and it is perfectly integrated with the surrounding iron trees.

At this moment, Mu Yunhai showed satisfaction in his eyes, slowly stroking his beard, and after a long time, he spoke.

"Three days have passed. I thought your wooden house had been built, but I didn't expect even a tree to interrupt it."

Chen Fan followed his reputation, Mu Yunhai was shaking his head and sighing.

After gritting his teeth, Chen Fan did not speak, and continued to compete with Tie Shu. In his bones, he was an extremely stubborn person. Ten cows couldn't hold him back when he was stubborn. Now he has been ridiculed by Mu Yunhai, even harder. He didn't care about the blood dripping.

Seeing this scene, Mu Yunhai's eyes were full of joy, and Chen Fan did not conceal his appreciation without paying attention.

What kind of person can reach the end of the road of martial arts?

This issue has been debated in the Kyushu mainland.

Some people say that they are selfish and selfish people, and some people say that they are those who kill fruit and decisively, but no matter what kind of person they want to go further on the road of martial arts, they must have a quality.

Perseverance!

That is the stubbornness of forgetting to sleep and eat for the purpose, and the determination to dare to give up life and forget death for an idea, for the grievance in the heart!

And these things, Mu Yunhai had seen all of them in Chen Fan.

In fact, the use of iron trees to build houses was only a test for him. It was an entry test. Mu Yunhai was also tested in this way.

Over the years, it's not that no one has come to practice in the Tianwu network, but without exception, all have stopped under the test of the iron tree.

They all believe that the road to martial arts is difficult and long, and time should not be wasted competing with a tree, but these people do not know the nature of martial arts, which is competition.

Compete with people, compete with monsters and beasts, compete with the world and everything, and compete with the Hongmeng universe!
