After dressing Da Zhuang, Wang Fen couldn't wait to take him back to the living room.

It was the fourth morning, and the warm golden sunlight poured in through the large floor-to-ceiling windows on the side, filling the slightly empty living room, giving it a warm and warm feeling of home.

Wang Fen first briefly tested his eyesight and hearing.

Dazhuang's eyesight has reached at least 4.0, and his hearing has also improved greatly, and he can hear the sound of mobile phone calls from ten meters away. The reaction speed is even faster and ridiculously fast, it is very close to zero reaction time, and a series of results make me realize that in addition to the change in body size, Da Zhuang's ability in all aspects has been greatly improved.

Once this is done, the all-important physical test begins.

To test the strength of people who have embarked on the road of evolution, ordinary barbells and the like are no longer suitable, and more advanced professional equipment Wang Fen does not have, only in the simplest way.

In order to test Da Zhuang's strength, Wang Fen specially took some leftover steel bars from a nearby construction site. They are available in diameters from 10 mm to 22 mm, as well as several thicker steel columns.

"Da Zhuang, come, try to break these steel bars. Wang Fen handed over a few steel bars to Da Zhuang and asked him to bend them. As for the breakage of these rebars, the thinnest rebar with a diameter of 10 mm requires at least 15 tons of tensile force.

Although Da Zhuang didn't understand the situation, he obediently took a few steel bars, feeling that it was very light, he tried to use a light force, and a few steel bars were bent like noodles, and even the thickest 22 mm diameter steel bars were effortlessly broken.

"Brother, why is Tongzigong so powerful?" Da Zhuang looked like a child who had discovered a novel toy, and excitedly twisted the thickest steel bar in his hand into a twist.

Da Zhuang has been working on the construction site, and although he could barely bend such a thick steel bar before, he could never do it so easily, which made him extremely impressed by Wang Fen's kung fu.

"Isn't it powerful to call Tong Zigong?" Wang Fen replied as a matter of course, and after seeing Da Zhuang's relaxed appearance, he stuffed Da Zhuang with an iron rod, "Come, try this one." ”

"Brother, it's so thick. Da Zhuang took the iron rod that was almost half a meter long, and said a little unconfidently.

This is an iron rod with a diameter of about four centimeters, which Wang Fen bought from the scrap acquisition station, and it is said that it was dismantled from a scrapped engineering vehicle.

"Brother, I have passed on such a powerful kung fu to you, come and try it, it doesn't matter if you can't move. Wang Fen smiled and encouraged, Da Zhuang's performance was very easy before, and Wang Fen asked him to challenge the high difficulty before.

Previously, the star core said that if you want to complete the mutation, you will not only have to rebuild the blood system, but then affect the entire body. It also requires Da Zhuang's brain and body to instinctively accept new abilities, and the best way is to let Da Zhuang challenge the limit, and in the process of breaking through the limit, stimulate the yin beast's high-energy factor hidden in the depths of the body.

"Brother, then I'll try it, don't blame me if you can't move. Although it didn't take long to wake up, Da Zhuang didn't feel tired. And after Wang Fen's encouragement, thinking of the magic of Tong Zigong, he looked at such a thick iron rod and was eager to try.

Wang Fen patted Da Zhuang's shoulder, encouraged him, and stepped aside.

"Hey!~" After Da Zhuang roared, he firmly grasped the two ends of the iron rod and broke it in the middle.

But after a while, Da Zhuang's face turned red, and the iron rod still showed a little bending. couldn't help but say to Wang Fen aggrievedly, "Brother, don't move." ”

"You try again, you can't just use brute force, now you are only using your own strength, you have to use your strength! Feel the feeling carefully, and see if there is any power in your body that has not been exerted?" Wang Fen was still a little unwilling, he had high expectations for the big strong mutation, and continued to encourage.

Wang Fen had tried it before, he could bend such a thick iron rod with his strength, as long as Da Zhuang could stimulate the power contained in his body, Da Zhuang who inherited half of his blood should have no problem.

Wang Fen has been looking at Da Zhuang with encouraging eyes, and Da Zhuang has only mutated to complete, and the functions of all aspects of his body have not yet kept up. He blushed and gritted his teeth, his arms slowly shaking from too much force, but the iron rod still didn't move.

Such a thick iron rod is still too difficult to be strong, the iron rod is already about the same thickness as the big strong arm bone, and it is also a high-grade steel on engineering vehicles. If he could bend it, his arm bones would be harder than steel.

"Ahhh His hands were tightly gripping the iron rod, his eyes were almost half protruding, and he didn't give up because his muscles were exposed.

As time passed, Da Zhuang's consciousness became more and more blurred. A sense of powerlessness gradually fills the body, but the desire for strength grows. Unconsciously, his body and brain continued to release various hormones, constantly stimulating the power contained in his two arms, and the loose skin on his arms seemed to slowly begin to tighten.

"Ahhh

Finally, Wang Fen smiled.

The iron rod slowly began to bend.

Soon, Wang Fenleng was relieved.

The big strong crotch is constantly swollen.

"Sting~~" At the moment when the iron rod was bent at 90 degrees, the big and strong baby also broke free from the shackles of the shorts, broke a hole in the shorts, and then turned into a huge straight and red iron rod, exuding bursts of heat and exposing the outside.

Da Zhuang looked at his hands in disbelief, is this the power of real martial arts.

"Brother, look, look, bend!" he couldn't help but jump and scream as he lifted the bent iron pillar.

Looking at the big and strong straight and majestic baby jumping wildly, Wang Fen's eyelids also jumped involuntarily, and his face stiffened and said for a while, "It's bent, it's bent." ”

"Brother, what's going on, why has it become so big. Da Zhuang, who came back to his senses, found that Wang Fen's eyes were not right, and finally his crotch baby, he never thought that his baby could be so big, so mighty and majestic.

"Why make all the fuss, what's so big about this, when your brother and I practiced this kung fu, before I passed on the gong to you, it was much bigger than you are now!" Wang Fen said with a nonchalant face, as if he felt that Da Zhuang was a little fuss and had never seen the world.

"Huh?" Da Zhuang looked at the baby carefully a few times, and then looked at Wang Fen with admiration on his face, it was bigger than this, how big was that.

Da Zhuang also had a nickname of "Silly Big Bird" before, which means that other people's stupid birds are big, but compared with the current baby, it can only be regarded as a little sparrow, and Wang Fen actually said that it is bigger than him now, so how mighty it should be.

Wang Fen didn't blush at the cowhide he bragged, but he still quietly pinched the star core in his pocket.
