The students burst into laughter. It was indeed the same as Qi Jing said. It would be impossible to be unlucky in this case.

"When the semen liquefied and started to flow, the contestants stepped on the starting line and entered the first level of the x line. What's the x line? The students who listened to my class last time should know."

"A variety of normal bacteria!"

"And immune cells!"

"Yes, there are immune cells here." Qi Jing pointed to some cells in the corner of the picture. "You have all learned immunology and you should know that the guys who have killed these days only have two kinds of things in their eyes. One is his own things, and the other is other things that must die."

"Sperm belongs to the second type, something else."

"The two sides hugged each other and fought. Do you think the sperm can be beaten?"

"cannot."

The answer was very fast this time, and the students all knew the power of immune cells and almost spoke in unison.

"Yes, the other party is immune cells, and it is impossible to beat it. No matter how many people there are, it is useless. This is just a meat bun to beat a dog, it's useless." Qi Jing asked again, "What should I do at this time?"

"If you can't beat it, just let it go."

"Yes, thirty-six strategies are the best!"

"Yes, I can only run." Qi Jing paused here and explained, "Actually, it is quite useful to run fast in this level. But remember, it is just useful. Do you know why?"

Everyone shook their heads, "Isn't it good to be fast?" They can stay away from the pursuit of immune cells, and at least they can survive."

Seeing that no one could answer, Qi Jing could only ask and answer: "Because they ran quickly, they were blind."

As soon as he finished speaking, Qi Jing cut through the ppt with his own pace and replaced it with another animation.

This is a picture from sophomore tissue embryology, which is covered with dense "titpoles". They are crowded with random swaying around, without a fixed direction of swimming at all.

"What should I do if the sperm cannot find its direction?"

"By luck."

"You guys learn very quickly." Qi Jing smiled and continued, "I am lucky and have the right sprinting direction and go straight to the cervix of the second level. Those who are lucky will go around in circles and be eaten; those who are swam in a strait will be eaten; those who are swam in the opposite direction will be not to mention them."

At this time, a male classmate suddenly mentioned: "I don't think swimming fast is completely useless."

The different voices did not visualize the students around them, but instead gave them some room for complaints and sufficient sense of expectation.

"There's a good show this time."

"Just directly, it's so strong."

"It's the one in Class 3 again. He just directly criticized the teacher in class. Do you really can't sit still?"

The troublemakers who disrupt the rhythm in the eyes of the students are treasures to Qi Jing.

This is the person he is waiting for: "What's your name?"

"Name?" The man didn't expect the other party to ask for the name directly. He was stunned for a while and said, "Hu Dongsheng, Class 4, 3rd Class."

Qi Jing nodded and silently wrote down: "Tell me what you think."

"The x path is not a two-dimensional planar structure. As long as the speed is not slow, you can still reach the cervix by going around a little." Hu Dongsheng made a spiral route with his finger to express his point of view, "The length of the route is a little far, but the probability is not low."

"Good, good, have some ideas." Qi Jing asked others with a smile, "Do you have any other opinions?"

No one else was silent.

The content of the part that Qi Jing picked is really biased and said in detail. Every step is broken down and it is normal that it cannot keep up with his rhythm.

"Of course, if you run fast, you should praise it. After all, there are some guys who are not very lucky, but they finally reached the second level by speed. We must commend such guys who win by their strength."

Qi Jing clapped his hands meaningfully, paused for a moment, and then cut the ppt back to the original sperm picture: "Although it's useless."

"Hahaha......"

Hu Dongsheng was a little dissatisfied and continued to ask: "Since we have reached the second level together, how can it be useless?"

"This is very easy to explain, because the energy of sperm is limited. After going around the x path several times, you can use up the energy. Don't think about it in the next few levels." Qi Jing pointed the screen with a pen, "There is no future for the road."

“Haha~”

Qi Jing turned several pages and found a picture of the uterus: "With great difficulty, they passed through the cervix and came to the uterus, which is the second level. It is already a lucky one for these little guys, but the reality is cruel. If you want to pass here, half of them will die."

A smile appeared on his lips: "Why do I say that it is not 1/3 of the dead, not 2/3 but half?"

"Because there are two fallopian tubes."

"Then what? You should have taught gynecology. Your Director Xiao can sit behind and watch!"

It is easy to memorize knowledge by rote, but it requires a certain threshold to apply it flexibly. If you are used to the exam-oriented education questions, it will be difficult to change your thinking.

However, Hu Dongsheng did not disappoint Qi Jing just now: "Because there is only one ovarian ovulation, and there are very few ovulations on both sides at the same time.

“Yes, that’s right.”

Qi Jing said: "Most ovaries do take a month off, so at this time, which ovaries are ovulating and sperm is not known. Choose one of them, you have to guess and start running. If you are wrong, you will be done. The fallopian tubes cannot go back."

"Senior, does this level tell us that choice phobia has no future?"

Qi Jingben wanted to continue to say that he didn't expect a girl to complain. Although she was not like Hu Dongsheng, at least her thinking was quicker than most people.

"I think they shouldn't be waiting in the uterus."

The girl nodded.

"If you have anything you want to say, it's a discussion meeting, not a class. When the discussion meeting ends, the most active people will be rewarded."

After saying that, he asked the girl's name.

The reward can naturally bring a wave of rhythm, making those students start to imagine infinitely. It is not a secret that Qi Jing is the son of the director of Danyang Hospital. In a short while, the guess about the reward began to become outrageous.

Some say that they can add regular points, some say that they can avoid one failure, and some even say stupid things that they can work directly in Danyang Hospital.

There are all blacklists in it that count all of them on Qi Jing.

"The next level is the third level, that is, the bottom of the ovaries." Qi Jing asked, "Here, the little guys will encounter a very critical problem."

He said halfway through the words, glanced at the classroom, and immediately Hu Dongsheng replied: "You must have eggs. If the ovaries do not ovulate, or if the eggs survive, it will be a waste of time."

"Where is the egg happening to be in the fallopian tube?"

"Then you can combine."

At this time, Qi Jing brought out another animated picture of a large number of sperm chasing eggs: "Boys play a lot of games, what do they think they look like?"

"Like a siege!"

"Isn't this the boss fight?"

"This is a boss battle that requires team cooperation. It's very difficult, but there are still strategies." Qi Jing explained, "The sperm head iron has something called apone that can dissolve a hole in the transparent belt of the egg."

"From the animation, sperm is much smaller, and just one sperm is far from enough, so it's about team cooperation.

And the most important thing is that as long as one passes through, the transparent bag will be closed and all the little guys outside will be killed.

So look, we were all comrades who dissolved the transparent belt together, but only the one who happened to finish the attack in the end grabbed the head, and these comrades couldn't even get an assist.
Chapter completed!
