After opening the metal door of the explosives warehouse, the door instantly moved back a thousand meters. Zhang Xu and the three of them were immediately pushed back by a huge strong wind. The strong air flow caused the missile to tilt slowly, making it difficult for the three of them to take a few steps outside.
Because of the wind, Zhang Xu knew the consequences of the missile tilting when flying at high speed, ranging from being far away from the target to being disintegrated and exploding on the spot.
Seeing that the three of them could not leave, Gao Peng seemed particularly anxious. Liu Qimeng remained unmoved and just raised her left hand. She wanted to use her freezing ability, but Zhang Xu stopped her.
"Don't go to such trouble, save your energy. When it tilts at a certain angle, the wind speed will decrease. At that time, we will go out again." Zhang Xu used Xuehe to feel the changes in the mouth of the warehouse, and his words also made the two of them relax a little.
It only lasts 14 seconds. These few seconds are very painful, because the speed of the intercontinental ballistic missile will continue to accelerate due to gravity. It has already passed the destination in these ten seconds. Assuming that the average flight speed is Mach 20, then During this time, it was probably nearly 10,000 meters away.
Zhang Xu's face was a little gloomy. He didn't expect the wind speed to be so strong. He was right not to be outside the missile at the beginning. He really couldn't handle it. Now he could only pray that the missile would tilt faster.
However, the more anxious he is at this moment, the more he will lose judgment. He can only keep calm and feel the changes in wind speed.
Suddenly, Zhang Xu wrapped Gao Peng and Liu Qimeng with blood and sent them out. At the same time, he stepped on his feet fiercely and jumped out.
Because of the step, the missile also lost its final balance, spinning, decomposing, and exploding in the air. The firelight shattered into dots of firelight, just like fireflies in summer.
Zhang Xu and the three of them held their hands together in the air to form a ring. He shouted: "Don't use your flying ability yet. We are flying towards the northwest wind, and we are more than 7,300 meters away." Pointing to the direction, Zhang Xu closed his feet and Flying towards Changqi City at an extremely fast speed.
Zhang Xu has blood and bone wings, so he has no problem landing safely. Gao Peng also has the flying ability of a dragonfly. As long as he spreads his wings at the right angle, he can take off. However, Liu Qimeng only has ice abilities and cannot fly, so he wants to land safely. There was no chance, so Zhang Xu flew away from the two of them first in order to build a relationship between them.

On a calm afternoon, everyone was sitting in a room of several hundred square meters. Due to the large number of people, the place seemed a bit crowded.
At this moment, an old man was facing a complex formula on a holographic screen. He was wearing a pair of brown glasses. Suddenly, the blue and white metal door outside slowly opened. When everyone was listening carefully, they were interrupted in this way, which made every scholar feel a little inexplicably annoyed.
"Jing Liang, why are you late? I remember that when you came to listen to my lectures in the past, you were always the first few to arrive." The old man held his eyes and asked with a smile in his eyes.
Iryotaro blushed a little, and kept clasping his thumb with his right middle finger, looking at the students around him, and finally replied in a low voice: "I'm sorry, Mr. Edward, I just forgot about your class because of the HeLa cell experiment. "
"Oh? What is it about?" Edward became interested and ignored the many students in front of him.
Everyone here is a biological talent from various regions, and some of them have even traveled thousands of miles away. The purpose of participating in this seminar is to ask questions to the genetics legend in front of them.
Although Iryotaro's grades were not very good, his studiousness and desire for knowledge impressed Edward every time.
In this seminar, every scholar who comes to attend the lecture will have the opportunity to present their scientific research results, and Edward will give them advice. This is because many people come in person instead of using holographic projection to attend the lecture, which is disrespectful to others.
But there is one person in front of me. Because he is late, he can be the first to get Dr. Edward's advice. This is of course the most jealous and irritating thing for everyone. Why is it not me who is late? !
But no one dared to ask, for fear of making Edward angry and being kicked out.
Iryotaro shyly scratched his head and took out a heavy report from his arms. He said: "It is about the idea and experiment of replacing new cells with HeLa cells."
When everyone heard this, the whole house immediately became noisy and discussed, and some even looked at the young man coldly.
This idea is very ridiculous. Why, because HeLa cells are a type of cancer cell. They were isolated from a patient by a doctor in 1951. They were finally given to a doctor. After culturing them, he found that HeLa cells only With enough nutrients, it can divide infinitely.
Since then, many people have used HeLa cells to conduct experiments, whether it is weightless experiments in space or high-pressure experiments on the seabed. They can basically be used.
But someone wants cancer cells to replace new cells. Is this possible?
Cancer cells are the result of accidental mistakes when the body produces cells. Cancer cells will not obey the body's orders because they only have the most primitive instinct, which is to divide and engulf, without any function.
In fact, everyone has more or less cancer cells, but the number is different. A small number of cancer cells will not cause physical discomfort, but only about 1 billion cancer cells may attract attention.
It is normal for everyone to laugh at Iryotaro, because replacing the original new cells with a cancer cell with a serious genetic defect seems simple, but in fact it is extremely difficult.
For example, it is like asking a blind man to play football. Cancer cells have lost their original functions. How can they complete this impossible task?
Many people will definitely say, if the blind man is equipped with an electronic eye or a brain receiver and other assistive devices, wouldn't he be able to play football?
Yes, but is it not necessary to spend time and effort teaching cancer cells what to do and then let it do its job? This kind of experiment has been done by people for a long time, and without exception, they all failed, including Edward who was reading the experiment report carefully.
It is easy to teach a blind person, but how can a group of cancer cells that ignore the rules be taught to be obedient? Moreover, the body's defense cells also dislike them, and it is also a big problem to get them to live in harmony.
Therefore, many people choose to eliminate cancer cell groups to save patients, instead of finding ways to let these cells continue to work in place of good cells.
After Edward read Ryotaro Ii's report for a few times, he pondered: "This idea is very good, but in practice we all know that it is too difficult... Cancer cells are almost irreversible. You should have read my paper from the year before last. Some cancer cells It is true that it can be converted into normal cells and continue to work for the body, but the cost is too high and the consumption cost is too high."
The carcinogenesis process is the result of the combined action of multiple factors. It is a chain reaction of genes one after another. Once started, it will continue like a domino until the end. There is almost no way back.
There are a small number of cancer cells that can transform, such as acute promyelocytes, which are a type of hematological malignant tumor. Using drugs such as retinoic acid or arsenic trioxide to induce differentiation, cancer cells can slowly transform into normal cells. But it's a waste of time and energy. It can be cured with a little radiotherapy.
I heard that humans are currently collecting a large amount of resources in order to significantly transform Mars. At the same time, in order to avoid excessive waste, many experiments or medical methods have also been suspended.
After saying that, Edward shook his head, a little disappointed, but also inexplicably familiar. Iryotaro looked like his younger self.
"Teacher, my method is to first use pARp inhibitor combined with radiotherapy to turn off the repair function of HeLa cells, and then use..." Seeing Edward shaking his head, Iryotaro said hurriedly, but he was interrupted by his hand.
Edward sighed: "Oh, I know, you want to say... after blocking the repair ability of cancer cells, it will not proliferate, and then use the editing technology cRISpR-cas9 to repair the lost sequences, so as to achieve complete repair. , right!" Edward's words were so powerful that Iryotaro was stunned for a moment, and then he nodded sharply.
What is cRISpR-cas9?
It is a weapon produced in the struggle between bacteria and viruses in the history of life evolution.
To put it simply, viruses can integrate their own genes into bacteria and use bacterial cellular tools to serve their own gene replication. In order to eliminate the foreign invading genes of viruses, bacteria have evolved the cRISpR-cas9 system.
After this system was discovered by humans, it has been widely used in medical, genetic, biological, cell and other fields.
"If you do this, you will also need to knock out a gene encoding the PD-1 protein in the cell genes, so that T lymphocytes will have 'trust' in HeLa cells..." At this point, Edward paused, and everyone also started to react. The mocking attitude at first became serious, because these words also benefited them a lot.
Dr. Edward did not continue speaking. He leaned on his back with his hands and left with a smile on his face, leaving only everyone with regretful faces and Ryotarou Ii with shining eyes.
"Thank you, teacher!" Iryotaro bowed deeply to Edward's leaving figure.
This is the default rule in their academic circles. Just give the other party an inspiration. If you speak it out, it will be more harmful than the gain if others find out.
Of course there will definitely be people who can understand, but their respective fields of research are different. They are all here to ask questions, so naturally many people need to ask Edward.
No one would take advantage of Ryotaro Ii and take other people's research results, which would be meaningless.
People with high IQs disdain to copy others. They like to break through themselves by following the path of their predecessors.
——
Iryotaro wiped the sweat from his forehead, and his white coat was stained with sweat. Now it was rest time. He took off the glasses on the bridge of his nose and looked at the video in his hand.
Inside was Professor Edward's latest video, and a big title came into view, 'A new era in the future? Changes in Dr. Edward's genetic code! '.
Iryotaro has entered middle age. Watching his former young teacher become old and gradually unable to achieve his goals, he becomes more convinced of the goal in his heart.
In the past, as a student, no one may have known who Ryotaro Ii was, but now he is an important figure in laying the foundation for genetic recombination.
It was his x13-tocy gene sequencing technology that allowed Edward to successfully invent genetic recombination technology!
