At this time, Dou Shishan began to slowly get used to the gravity field that he had felt pressured before, but he didn't dare to make any drastic movements.

With the passage of time, Dou Shishan felt that such a stalemate was not a solution, as the saying goes, there is no motivation without pressure, so he simply doubled the gravity. With the increase of gravity multiple, this increase in gravity was enough for Dou Shishan to endure, and he was forced to fall to the ground by being forced to stand. And he could feel the changes taking place within his body, and the marrow washing meridian was moving faster.

At this moment, Dou Shishan couldn't help but think of some athletes in his previous life, and some people who improved their physical limits went to some plateau areas to practice, so that their body's glycolysis took a special route, improve the ability of cells to resist hypoxia, reduce the affinity between hemoglobin and oxygen, and use tissues to obtain oxygen. Isn't it that I am under the pressure of gravity now to improve the resistance of my cells, and I will not feel hypoxia and fatigue even after strenuous activities in the future.

Dou Shishan thought about it, and with a ruthlessness in his heart, he doubled the gravity, so that his body that had just stood up was overwhelmed again. The marrow cleansing meridian runs at high speed in its body, and the true qi in its body also warms its body, supporting it in its struggle with the external environment.

I don't know how long it took, Dou Shishan felt that for a century, his body and mind began to become numb, and the only thought in his heart was to support it. Perhaps for many men, A-level physical fitness is nothing at all, and some people are even born with S-level physical fitness. But A-level physical fitness is hard-won for Dou Shishan, who has been promoted from F-level.

Jiang Xing next to him had been accompanying Dou Shishan by his side, and he was also worried about it, watching Dou Shishan struggling to support, his slightly long bangs were already wet with sweat, clinging to his full forehead. Sweat accumulated on the cold face and flowed down the bridge of the nose, like a mountain, and from the chin down the neck to the collar, full of an indescribable temptation. Although the clothes on his body have been changed into loose ones after entering the training room, they are still wet with sweat and clinging to his body, outlining a childish and initially perfect figure. Although Dou Shishan is only five or six years old, the body exercised and the precocious body in this world make the body of Dou Shishan, who is five or six meters old, look full of temptation. Of course, all these scenery fell into the eyes of Jiang Xing, who was not very familiar with the world, and there was no other feeling.

Dou Shishan couldn't help but go crazy again, and increased the gravity by two times, and the gravity had developed by 55 times. It's a crazy move, and the average normal B-level physical fitness can support 50 times the gravity. The consequence of the madness was that Dou Shishan was directly crushed to the ground, and the whole person lay on the carpet of the training room with the word "big" without any image at all.

Dou Shishan felt that his body was clamoring to give up, but his spirit was getting better and better, supporting tenaciously and never giving up. The marrow washing process is running again and again, and the true qi flows in the body according to a certain route, as if it is always repairing the dark wounds in the body due to the forced increase of gravity.

Thick and thin, after a certain limit is exceeded, everything will change and be recoded. After Dou Shishan violently increased the gravity, more than his body could bear, and he felt that everything was starting to develop in another direction. There was a faint feeling that when he reached the critical point of breakthrough, he was just one step away.

Jiang Xing on the side watched Dou Shishan increase his gravity as if he was dying, and wanted to stop it, but found that his body data was changing in wavy lines, and there was an unknown force that helped him repair his body when he damaged his body. Jiang Xing had never seen anything like this, and he didn't dare to interrupt Dou Shishan's cultivation in vain. can only be anxious on the sidelines, secretly hoping that Dou Shishan can get through this bottleneck.

The Dou Hu family outside the training room is also very anxious, and now that their youngest son is in retreat and practicing, it has been nearly a day, and they don't know if the situation is good or bad now. Because now they found out that the youngest son had changed the password of the training room at some point!

Dou Hu was told by his eldest son at dinner that his younger son went to retreat to improve his physical fitness, and he knew that his younger son was now at the B level, and it was not easy for his son to be promoted to the A level, after all, it was not easy to improve his physical fitness, and there were very few existences like his son. While he was proud of his son, he was also deeply worried that A-class physical fitness would be the bottom line of the Space Marine, and he would have no reason to prevent him from joining the army in the future.

She Yu listened to the words of the eldest son, and her heart was immediately pinched, she was worried when her younger son's physical fitness was low, but now that her physical fitness is good, she is still not worried. It's good to follow your own planting or medicine, so why bother to improve your physical fitness. Generally, the physical fitness of females is around the B level, and there are few who are as restless as the younger son. It was a matter of a moment when Yu Yu thought like this, and her heart was full of worries about her son.

Tong Zhongzheng and Dou Wen, although they were born with S-level physical fitness, but now watching the little brother's step-by-step improvement, he has a deep sense of pressure in addition to being anxious about it. The younger brother is getting better and better, and he almost doesn't need the protection of his brother, whether he will let his younger brother protect him one day, I feel a chill when I think about it, and I still have to work hard to improve my strength.

Tong Zhongzheng and Dou Wen glanced at each other, immediately understood what the other party was thinking, and couldn't help but nod to the other party.

Dou Shishan was embarrassed by fifty-five times the gravity, but he also groped for the threshold of breakthrough.

Suddenly, Dou Shishan felt that the true qi of his physical strength began to burst into a series of energy, making him feel frightened at the same time in pain, what was the situation?

Although he was shocked, Dou Shishan did not mess with himself, and tried his best to control the airflow in his body. But the effect is not satisfactory, so that Dou Shishan is frustrated and unwilling at the same time, do you give up because of this failure, thinking that after failure, you will have to live the life of a husband and a child, Dou Shishan is even more determined that he will not give up, not to mention that he did not give up these two words in his dictionary!

Suddenly, a storm of energy burst out of perseverance, trying to suppress the restless air flow in the body. Fortunately, he successfully suppressed the true qi of his physical fitness, and unconsciously, in the process, Dou Shishan found that his physical strength had broken through, and his true qi had become thicker than before, and the road to operation was wider. Thinking about it, Dou Shishan, who felt tired, fell asleep deeply.

Jiang Xing next to him felt that Dou Shishan's data had recovered calmly and had improved qualitatively, and he was also relieved. I really sweated for it just now, but luckily everything is getting better. Seeing that it is almost dawn, let him rest quietly for a while.

When Dou Shishan opened his eyes again, it was already noon the next day.

Dou Shishan woke up from the state of confusion that he had just woken up, and saw that the time was almost noon, it was too bad that he fell asleep at the end, and his family should be worried about it!
