This is a little different from the feeling of being pricked by an anesthetic needle when the robber took out a dagger and stabbed him yesterday. And Zheng Biao's right arm is still raised in front of his chest at the moment, not as if he is anesthetized.

Could it be that the anesthetic needle has failed?

The anesthetic needles in my mind have changed from 34 to 33, and it seems that one has indeed been consumed, but why didn't Zheng Biao succeed in anesthesia?

Zheng Biao was also shocked, and the reason for the shock was that he had just smashed a punch on Qi Bo's chest, as if his right arm suddenly went numb a moment before he hit Qi Bo's chest, and he felt a little weak.

And now the whole right arm is still a little numb, although it can barely be raised, but it is obviously not as flexible as before.

After Qi Bo carefully observed Zheng Biao's expression and his muscular body, he immediately understood. His injection is not ineffective, but because Zheng Biao, a bear, has been exercising muscles, his body is too strong, and his weight is close to 15 times that of a normal person at the same height. Just like the usual anesthesia patients before surgery, some patients who are particularly fat or particularly strong need to use a larger dose of anesthetic injections than ordinary people, otherwise the effect of anesthesia will not be effective.

The same dose of anesthetic on cattle and sheep will certainly have a very different effect.

Probably this is the reason, the dose of anesthetic in these anesthetic needles is certain, Zheng Biao is strong, so the dose of anesthetic he needs to anesthetize is also more, and it may take two anesthetic needles to completely anesthetize one of his thick arms.

Medical Ethics System ...... No, this immoral system still follows the laws of science!

When Qi Bo was about to send out another anesthetic needle, and put a few needles on Zheng Biao's other arm and two legs, so that Zheng Biao completely lost his combat effectiveness, he found that the anesthetic needle in his mind could not be sent. In desperation, he realized that when he wanted to send out the anesthetic needle again to attack, a vague and small number appeared on the barrel of the anesthetic needle, as if it was a countdown.

Is there a cooling-off period for the use of anesthetic needles?

How did it not before?

Zibo recalled carefully...... In the past, when he used these anesthetic needles, he had been at intervals for a certain period of time, and he had not pricked someone like this continuously.

Fortunately, if you look closely, the countdown is only a few seconds.

Zheng Biao waved his inflexible right arm very irritably, and then swayed his body from side to side and rushed towards Qi Bo again, this time he used his somewhat paralyzed right hand as a cover, and it was his left hand that attacked!

Qi Bo didn't have a trick, just continued to retreat and try his best to dodge, until there was no way to retreat, the cooldown time of the anesthetic needle finally arrived! Qi Bo pricked another anesthetic needle, pierced Zheng Biao's left arm, but Zheng Biao's blow had also attacked, Qi Bo still couldn't dodge Zheng Biao's very professional blow, and he was punched by Zheng Biao in the face, and was directly knocked to the ground, half of his face was swollen.

This is still the result of being injected with anesthetic, if you take this punch directly, maybe half of Qi Bo's teeth will be knocked away by Zheng Biao, this Zheng Biao has practiced muscles and boxing skills for so many years, but it is not an ordinary toughness!

"Qi Bo, admit defeat! Qi Bo, drill your hips!" Xiao Guangfu and Feng Kun shouted together.

A group of students and colleagues in the audience also looked at the stage, some of them were pity, some were gloating, some were indifferent, and all kinds of expressions were there.

As for Qi Bo being knocked to the ground by Zheng Biao, they had long expected it, and it was really not interesting to watch a one-sided game. It's just that I will admire Qi Bo's courage or stupidity in my heart, and I have to hold on to it like this.

"Qi Bo has fallen to the ground! Zheng Biao, stop fighting!" Liang Ling shouted to Zheng Biao before attempting to rush into the ring, only to be stopped again by two gym staff. She was so angry that she got into a big fight with the staff, and then turned to her classmates for help, but no one paid any attention to her.

There are indeed sympathizers for Qi Bo among his classmates, but in the medical system of Yunfeng City, he can't afford to provoke the Zheng family, so he can only express sympathy in his heart at the moment, and then feel that Qi Bo is too stupid, it's all like this, why don't you quickly admit defeat?

Zheng Biao raised his fists to show off to everyone in the audience, and then walked over to Qi Bo step by step, the numbness of his arms made him a little unhappy, but the opponent Qi Bo was too weak and had been knocked to the ground, now he just stepped forward and stepped on his face a few times and waited for him to admit defeat and drill his hips to end the battle.

Unexpectedly, just as Zheng Biao was about to step on Qi Bo's face and force Qi Bo to admit defeat and drill his crotch, Qi Bo suddenly rolled to the side and stood up, retreated to a corner of the ring step by step, leaned on the rope rail, wiped the blood from the corner of his mouth, and looked at Zheng Biao.

"Don't admit defeat yet? Look how I beat you to death!" Zheng Biao waved his numb arms irritably, and approached Qi Bo step by step again.

"It's you!" Zibo shifted his position step by step on the edge of the ring rope rail, then observed the cooldown timer of the syringe in his field of vision.

He figured it out this time, the cooldown countdown was about fifteen seconds, and the needle to Zheng Biao again had to be fifteen seconds after the previous needle, so after being knocked down just now, he didn't get up, he was deliberately delaying time.

"Look for death!" Zheng Biao rushed towards Qi Bo, and kicked Qi Bo violently because his arm was uncomfortable.

After all, kicking is not comparable to boxing, although it is very fierce, it is also easy to judge the direction and dodge, even if Qi Bo is not a professional boxer, he can clearly judge and dodge Zheng Biao's kick with a clear direction this time. Of course, the cooldown time for the anesthetic needle has also come again, and after dodging this kick, Qi Bo did not hesitate to pierce another numbing needle into Zheng Biao's leg.

One of Zheng Biao's legs immediately became less flexible, coupled with the numbness and uncontrollable feeling on his arm, which made him more and more irritable, he yelled and pounced on Qi Bo again, a burst of punches and kicks, Qi Bo couldn't hide for a while, so he had to hold his head and bend down to let Zheng Biao beat him all the time.

"If you don't admit defeat, you will kill him! Kill him!" Xiao Guangfu and Feng Kun's shouts became even more fanatical.

"Stop fighting! Stop them! They're going to die! You're doctors! Cold-blooded animals!" Liang Ling shouted, guessing that Qi Bo must be refusing to admit defeat for the sake of dignity. But does it make sense to hold on like this?

"You let Qi Bo quickly admit defeat!" The onlookers couldn't help but reply to Liang Ling.

Obviously, you can end the game if you admit defeat, but the shape at this moment is that you will not admit defeat if you are beaten, and one on the stage is willing to fight and one is willing to suffer, who can control them?

"Zibbo's brain is in water, in the water. Another student replied to the classmate just now.

At this moment, Zheng Biao's two arms and one leg were paralyzed, and he looked very inflexible, especially when he was beaten hard and tired, he couldn't maintain a standard form after being tired, and for a while, the door in his chest was wide open.

At this point, Zibo finally found an opportunity...... Without hesitation, he threw out one of the arms that he had bent over to protect his head with the help of the power of his waist, and the Jedi counterattacked and slammed an uppercut into Zheng Biao's exposed space, hitting Zheng Biao's chin firmly.

Although Qi Bo's fists are not as fierce as Zheng Biao's, people's chins are still much weaker than people's fists. Qi Bo's hook hit the point, directly knocking Zheng Biao's head backwards, and the whole strong body stumbled backwards.
