This thought made Feng Chenyu even more convinced that when those tricks and martial arts were combined to achieve complementary effects, it would be perfect.

Feng Chenyu looked at the above practice methods, how to charge strength, etc., and began to conduct countless simulation exercises in his mind.

After meditating for about a few hours, Feng Chenyu had already thoroughly analyzed that deadly iron fist in his mind, and it was only a few hours before he completely analyzed it, which was a very amazing speed, and of course it was the effect of that pill that his brain turned so fast.

Feng Chenyu slowly opened his eyes, now that he had thoroughly analyzed that deadly iron fist, now he had to practice, after all, talking on paper was empty talk, and it had to be practiced.

At this time, Feng Chenyu didn't bother to go outside, and went directly to the Dharma cave against a relatively solid wall to prepare to try his fist.

Feng Chenyu touched it himself and found that the hardness was almost the same as that of a brick.

If Feng Chenyu wanted to know how strong the deadly iron fist of the Dao was, he had to make a comparison.

First of all, Feng Chenyu had to use ordinary boxing, and hit the wall with his fist in no order, Feng Chenyu knew that his body's performance had improved from the time he hit the tree just now, so he was not afraid of his fist being broken.

After Feng Chenyu used all his strength, he only left cracks in that solid wall, which was already very powerful.

Feng Chenyu can use his internal qi to crack the solid wall, which is already considered a bunker, but Feng Chenyu is not satisfied with this, he knows that if the old monk is there, it is estimated that he will knock down this wall with one punch.

Next, Feng Chenyu raised his internal strength to the peak, now internal strength is already the foundation of martial arts, without internal strength, it is impossible for you to perform real martial arts.

Feng Chenyu took a deep breath, learned the method he had told himself, and used the strength of his whole body to penetrate his right fist.

In this accumulation process, Feng Chenyu seemed to be accumulating anger, just waiting for an opportunity to open up his firepower.

Suddenly, Feng Chenyu roared, the green tendons on his neck came out, and his face was flushed, looking more like a rage.

Feng Chen's feathers and horses were one, and he used all the strength of his body to concentrate his right fist and use the "deadly iron fist".

With a bang, a punch slammed into the wall, and all sides were filled with sand and dirt carried by the fist wind.

The smoke fascinated Feng Chenyu's eyes, and he couldn't see clearly for a short time, when the smoke passed.

When he saw the reaction on the wall, he was simply stunned.

His fist actually inserted into the solid wall, and the whole fist was sunk in, but it didn't break or shatter the wall.

This reaction simply made Feng Chenyu ecstatic, you must know that breaking the wall does not mean that your destructive power is very strong.

It's like a bullet that goes into a window and leaves only a small hole, but doesn't shatter it.

Feng Chenyu's deadly iron fist was almost the same principle as a bullet, and Feng Chenyu now dared to say that this punch could even pierce a person's heart.

Killing a person with one punch, how powerful is this, and just the power of hitting that earthen wall just now Feng Chenyu knew that even body armor could not stop this deadly iron fist, this deadly iron fist was really fierce, worthy of being left by Damour.

Feng Chenyu's current performance is like a superman, which is completely incredible, but he knows that he himself is not a superman, and he is just a blessing that he can break through the wall or drag his internal qi.

But even if this is not very happy, the old monk estimates that he can knock down the gun with a single punch, and he has to use all his strength to penetrate it, how big the gap is.

The old monk said that martial arts must cooperate with internal force in order to exert effect, Feng Chenyu is now punching through the wall or internal force to help him, if there is no internal force, Feng Chenyu estimates that it would be good if he can break a plank with one punch.

When there is internal force, the lethal iron fist can break through a wall, it is still solid, but when there is no internal force, it can break a plank at most. This difference once again tells you how important internal forces are.

But after a brief moment of surprise, after using the deadly iron fist, Feng Chenyu felt as if his body had been hollowed out, and he had no strength at all, and he fell down softly like that.

With that feeling of soreness and weakness all over his body, Feng Chenyu now finally understood the duplicity of the deadly iron fist.

This thing is very hard, but if you don't hit it, you'll be a fat sheep for anyone to slaughter, so this thing can only be used as the last trick.

Feng Chenyu fell to the ground softly, without any strength in his body, and didn't want to move anything.

Even if Feng Chenyu fell, he was still excited, this move was too hard, it exploded, if Feng Chenyu went to participate in that martial arts competition in his current situation, what kind of karate competition in the Sun Empire, and the boxing match in the American Kingdom would simply blow them up.

Feng Chenyu's fatal iron fist can kill the boxing king of the American Kingdom in seconds with one punch, and at that time, it was for our Great Heavenly Dynasty to win glory.

Feng Chenyu decided at this time that if he could go out, he would definitely participate in some international competition, and then win glory for the Great Heavenly Empire.

Feng Chenyu hates those little deflated Sun Empire people very much, and it is not happy to see those little low Feng Chenyu, and the current Feng Chenyu is estimated to be able to pinch and kill one of them with one hand.

At this moment, Feng Chenyu still didn't know what to do, his dream would really come true in the future, when the Great Celestial Empire and the Sun Empire went to war in the future, there would be a madman in the attacking troops of the Great Celestial Empire, who killed a little devil with one punch and killed a little deflated three with one palm.
