Over the next few weeks, the changes that happened to Zheng Guoxing left every fight center regular in jaw-dropping.

The executive of this headhunting company insisted on training under the guidance of Su Ziyu at least three to four times a week, and the cumbersome belly was gone, and the original stubborn fat meat had begun to transform into strong and strong tendon meat, and the training progress in all aspects was rapid, even surpassing that of many long-term training free fighting enthusiasts.

Such an astonishing change is shown in the eyes of everyone, and the cascading effect is undoubtedly amazing, in the past week, Su Ziyu has had four or five more students, although this will inevitably thin his energy, but the effect of the guidance and training is enough to make every student ecstatic, no matter what purpose they originally had to exercise.

There were even a few students from other coaches who came to contact him, and although Su Ziyu was surprised, he could only politely refuse.

Maybe because of his qualifications, his relationship with the other coaches in the fight center is relatively average, these people who practice free fighting have a sense of arrogance in their bones, and they are a little lukewarm to Su Ziyu, who has a blank competition performance and learning experience, and he is not interested in rushing to please anyone, so at most he nods to say hello.

It stands to reason that the client is God, and it is completely personal freedom for the trainees to choose which coach they want to choose. But Su Ziyu understood that this thing couldn't be done like this, he had been training well with a certain coach, but suddenly came to practice by himself, and the impact would be too bad.

To put it mildly, this is to sweep the face of colleagues, and if it is bigger, it can be said to be stealing people's jobs, and no one can bear it if they change, this is simply a tacit understanding that does not need to be explained.

There is a good saying that cutting off people's wealth is tantamount to killing their parents, and smashing people's jobs will inevitably lead to enmity for the ninth generation.

The words are not rough, it is the same in any line, when he was a teenager, he went out to survive alone, Su Ziyu understands this truth better.

So he was unmoved by the few students who found him one after another, but just explained with kind words and refused with a smile.

But when such things happen too much, it is inevitable that some people will feel uncomfortable, so on this day, when a coach surnamed Tan suddenly came over, Su Ziyu was not surprised at all.

This instructor's name is Tan Ke, regardless of his seniority, he is the number one person in the fighting center, proficient in sanda, martial arts, and even went to Thailand to refine Muay Thai for a few years, and has won several championships, so his momentum is naturally not ordinary.

Tan Ke had dark skin, a lean short hair, and a burly physique, and when he saw Su Ziyu finish his guidance to the two students, he walked over.

"Coach Su, they all practice free fighting, I don't know if I have time to fight?"

The other party didn't mention that the students wanted to change coaches at all, and Su Ziyu didn't say much, he smiled lightly: "That's it, why don't you wait for the students to leave?"

Tan Ke's expression was stunned, as if he didn't expect him to say this. When Chen Xiaofeng mentioned Su Ziyu, he just said that his legs were very heavy, but he was a little vague, so he didn't pay attention to it at all, and now when he heard Su Ziyu's answer, he just didn't want to lose face in front of others. This is also in line with his heart, so he nodded immediately: "Okay, then you are busy first." ”

The Fight Center is usually open until 10 p.m., but after 9:30 p.m., most of the students are gone, and only the instructors remain in the center. Of course, this is not a coincidence, but they all saw the scene of Tan Keyo's battle and wanted to know the result, so they stayed to watch the battle.

Over there, Tan Ke couldn't wait to move his body, Su Ziyu also stepped forward, and the eyes of the coaches and even the nearby staff focused on the two of them.

"Almost, Coach Su, shall we start here?" Tan Ke walked under the ring and smiled proudly.

Su Ziyu shook his head, walked to an 80KG sandbag, reached out and patted the sandbag, making a few muffled sounds.

"What?" Tan Ke raised his eyebrows, his face sank, and he didn't understand what he meant.

"Actually, you don't have to do it, otherwise, I'll hit the sandbag, Coach Tan, take a look." ”

Su Ziyu's footsteps moved slightly, to the front of the sandbag, took a deep breath, put his mind into his body, and with a kick, the strength of his legs, hips, waist and even his spine was instantly kneaded into a force, and his right fist was closed to his waist, and his essence suddenly exploded, and he suddenly punched out!

Burst!

There was only a low and soft sound, and his fist had already been dug deep into the middle of the sandbag!

The audience was amazed!

A group of coaches, including Chen Xiaofeng, and other staff members were originally ready to watch a dragon fight, but they never wanted to witness this scene with their own eyes.

There was no momentum, no shouting tricks, only a moment that was so fast that it was difficult to see, and Su Ziyu's fist had already penetrated into the sandbag!

Ordinary people may be surprised and don't quite know what this means, but now the people in the martial arts center are more or less familiar with some free fighting and training equipment, and they are relatively professional and have a deeper understanding.

The fighting center uses professional sandbags specially made by regular manufacturers, although the name is sandbags, but they are not filled with sand. This one by Su Ziyu is an 80KG professional sandbag, the surface is stitched with microfiber fabric, the cushioning layer is EVA soft foam, sponge composite, the inside is oxford cloth, and finally filled with rags. The microfiber fabric simulates human skin, while the padding material is like muscle fibers in stripes, and the internal structure of the entire sandbag is as close to the human body as possible, after all, the object of the fight itself is human.

This kind of professional sandbag, except for damage due to long-term use, it is logically impossible to break it at all!

That's right, not the slightest possibility!

The sandbag that could not be broken was now actually pierced by Su Ziyu's punch, this strength and skill can no longer be described as terrifying, it can be said that it is absolutely non-human, beyond the limit of the human body.

Everyone who was present and there was a chill down their spines, and they were completely shocked.

Think about it a little deeper, if you want to give a more vivid example, Su Ziyu's punch just now, if it is replaced by hitting others, the effect is to directly blast the body and drill into the human body!

Su Ziyu slowly pulled out his fist from the sandbag, and even brought out some filling materials and sprinkled them on the ground. To be able to penetrate this professional sandbag, he didn't expect it, originally he just wanted Tan Ke and others to see his fist power and retreat, but he didn't expect the effect to be achieved, but it was a little beyond expectations.

"Coach Tan, I understand what you mean by looking for me. I will never accept your students, they are all my own people, so as not to hurt the harmony, let's expose it, right?"

Looking at the stunned crowd, Su Ziyu was also a little helpless, and he knew that he should be more restrained.
