This is a bit different from the robber who bravely fought against the bag yesterday. When the robber took out a dagger and stabbed him, he suddenly felt soft after being stabbed by an anesthesia needle. Moreover, Zheng Biao's right arm was still raised in front of his chest at this moment, not as if he was being anesthetized.

Could it be that the anesthesia needle has failed?

The anesthesia needle in my mind changed from 34 to 33. It seems that one of them has been consumed, but why can't it be successfully anesthetized by Zheng Biao?

Zheng Biao was also shocked. The reason for the shock was that he just punched Qi Bo's chest, as if the moment before hitting Qi Bo's chest, his right arm suddenly numbed and felt like he couldn't use any force.

Moreover, the entire right arm is still a little numb. Although it can be lifted up barely, it is obviously not as flexible as before.

After carefully observing Zheng Biao's expression and his strong body, Qi Bo immediately understood. This injection was not without effect, but because Zheng Biao, the bear, has been training muscles and is too strong. At the same height, his weight is close to 1.5 times that of a normal person. Just like patients who are anesthetized before surgery, some patients are particularly fat or strong, and the dose of anesthetic injections required is larger than that of ordinary people, otherwise they will not have the effect of anesthesia.

The same dose of anesthetic drugs will definitely have a very different effect when used on cows and sheep.

This is probably the reason. The dose of anesthetics in these anesthetic needles is certain. Zheng Biao is in good health, so the dose of anesthetics required for anesthetics is also higher. Two anesthetic needles may be needed to completely anesthetize one of his thick arms.

Medical ethics system... No, this unethics system still follows scientific laws!

When Qi Bo was about to issue another anesthesia needle and put a few needles on Zheng Biao's other arm and legs, causing Zheng Biao to completely lose his combat effectiveness, he found that the anesthesia needle in his mind could not be emitted. In a hurry, he realized that when he wanted to issue anesthesia needle again to attack, another row of vague, very small numbers appeared on the syringe of the anesthesia needle, as if countdown.

Is there a cooling period for the use of anesthesia needles?

Why didn't it before?

Qi Bo recalled carefully... In the past, when he used these anesthesia needles, he had a certain time interval, and he did not stab someone continuously like this.

Fortunately, I looked over carefully and the countdown was only a few seconds.

Zheng Biao waved his inflexible right arm irritably, then shook his body left and right and rushed towards Qi Bo again. This time, he used his numb right hand as a cover, and the one he attacked was his left hand!

Qi Bo did not have any tricks, but kept retreating and tried his best to dodge it. Until he could not retreat, the cooling time for the anesthesia needle finally came! Qi Bo stabbed another anesthetic needle and stabbed it on Zheng Biao's left arm, but Zheng Biao's attack had also attacked. Qi Bo still could not avoid Zheng Biao's very professional attack. He was punched hard on his face and was directly knocked to the ground, with half of his face swollen.

This is the result of being given anesthetic injection. If you get this punch directly, Qi Bo's half of his teeth may have been knocked away by Zheng Biao. Zheng Biao has practiced his muscles and boxing skills for so many years, so he is not ordinary tough!

"Qi Bo! Give up the loss! Qi Bo! Get into the hips!" Xiao Guangfu and Feng Kun shouted together.

The students and colleagues in the audience also looked at the stage, with some pity, some gloating, some indifferent and indifferent expressions.

They had long expected that Qi Bo was knocked to the ground by Zheng Biao. It was really meaningless to watch a one-sided game. They just admired Qi Bo's courage or silly in their hearts. They had to hold on if they were like this.

"Qi Bo has fallen to the ground! Zheng Biao, stop hitting him!" Liang Ling shouted to Zheng Biao, then tried to rush to the ring, but was stopped by the two staff members of the boxing gym again. She was so angry that she started a big arguing with the staff, then turned around and asked her classmates for help, but no one paid attention to her.

There are indeed people who sympathize with Qi Bo among the classmates, but in the Yunfeng City medical system, they can't afford to provoke the Zheng family. At this moment, they can only express their sympathy in their hearts. Then they think Qi Bo is too stupid. He is like this, so why don't you admit defeat?

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

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

"I still don't admit defeat? I'm so kind! Let's see how I beat you to death!" Zheng Biao waved his numb arms irritatedly, and approached Qi Bo step by step again.

"It's you who should admit defeat!" Qi Bo moved his position step by step beside the ring rope bar, and then observed the cooling countdown prompt of the syringe in his field of view.

He figured it out this time, the cooling countdown was about fifteen seconds. He had to give Zheng Biao another injection fifteen seconds before the previous injection, so after being knocked down just now, he didn't get up, deliberately delaying the time.

"Looking for death!" Zheng Biao rushed towards Qi Bo, and because his arm was uncomfortable, he kicked Qi Bo suddenly.

After all, kicking is not as good as boxing. Although it is very fierce, it is easy to judge the direction and avoid it. Even if Qi Bo is not a professional boxer, he can clearly avoid Zheng Biao's kick in a clear direction. Of course, the cooling time for the anesthesia needle has also arrived again. After Qi Bo avoided this kick, he stabbed another needle of anesthetic on Zheng Biao's leg without hesitation.

One of Zheng Biao's legs immediately became less flexible, and the numbness and uncontrollability on his arms made him more irritable. He roared and rushed towards Qi Bo again. After a while, Qi Bo could not dodge for a while, so he had to hug his head and bend down and let Zheng Biao beat him hard.

"If you don't admit defeat, beat him to death! Beat him to death!" Xiao Guangfu and Feng Kun's shouts became even more fanatical.

"Stop fighting! You guys stop them! It's going to be killed! You are doctors! One by one, cold-blooded animals!" Liang Ling shouted, guessing that Qi Bo must be for dignity and refused to admit defeat. But is it meaningful to hold on like this?

"You ask Qi Bo to admit defeat!" The onlooker couldn't help but say something back to Liang Ling.

It is obvious that if you admit defeat, you can end the game, but the situation at this moment is that you are beaten and refuse to give up. One person on the stage is willing to beat the other. Who can control them?

"Qi Bo's mind is flooded, and there is flood." Another classmate replied to the classmate just now.

At this moment, Zheng Biao's arms and one leg were paralyzed, and he seemed very inflexible, especially after a fierce attack, the movement of closing his fists could not maintain the standard shape after being tired. For a moment, the door on his chest was wide open.

At this time, Qi Bo finally found an opportunity... Without hesitation, he threw out one of his arm that had bent down to protect his head with the help of his waist, and counterattacked the air exposed by Zheng Biao, and hit Zheng Biao hard on the chin.

Although Qi Bo's fist is not as fierce as Zheng Biao, his chin is still much weaker than his fist. Qi Bo's uppercut hit him right, directly tilting Zheng Biao's head backwards, and his strong body stumbled backwards.
