After taking several buses and high-speed trains, I returned to Jiangcheng University in a panic.

Just got off the bus.

"Senior brother..." He called out as crisply as an oriole, and the bright girl was still so innocent.

Li Qingye nodded: "How are you lately?"

The two of them were walking and talking wordlessly.

Liu Xiaoli seemed to feel Li Qingye's inner sorrow, so she kept the story short: "Over in the laboratory, I have given people a holiday, and there are only two security guards."

"Thank you."

"You're welcome. Senior brother has helped me so much in the past. I can still do this little thing." Liu Xiaoli replied gently.

Unconsciously, the two of them came to a teaching building. The girl handed him the key to the laboratory and said goodbye.

Standing at the door of his tutor's office, Li Qingye knocked on the door.

"Come in."

"boss."

"Huh?" The instructor looked up and saw Li Qingye, who was covered with stubble and looked decadent. He sighed slightly in his heart, and then said with a smile: "Your visa has been processed, and the flight is on May 22. During this time, if you adjust your mood, there will be no obstacles in your life that you can’t overcome.”

Li Qingye nodded calmly: "Thank you for your concern, boss. I'll go to the company first to have a look."

"Go! Don't forget the flight time."

After bidding farewell to his mentor, Li Qingye walked alone on the path of Luojia Mountain, with only scattered petals left on the cherry trees beside the road.

A breeze blew across my face, and the remaining cherry blossoms on the branches fell lightly.

Sit on a bench and watch the flowers fall.

"Life is so fragile!" Li Qingye sighed.

Say a final farewell to the lost youth.

Farewell, Jiangcheng University.

Farewell, my innocence and youth.

At the subway station, the low-pitched tram slowly stopped, and you swiped your card to get on the train. The complexity in the carriage was incompatible with the homeless-like Li Qingye.

Soon the tram arrived at its destination - Jiangcheng South Station.

I took the bus again and came to a company located near Xiaogang Village. At the door of an old small factory, there was a plaque saying "Caixin Cosmetics R\u0026D Center".

The security guard at the door was smoking a pipe. Suddenly he saw him coming and came out hesitantly: "Young man... you are..."

"Old Wang, it's me." Li Qingye took out the keychain in his hand and shook it.

Only then did security guard Lao Wang react and quickly opened the door: "Boss, I almost don't recognize you when you look like this."

"Well, Lao Wang, is there nothing going on during this time?"

Lao Wang thought for a while and then talked about some trivial matters. Li Qingye gave some casual instructions and entered the laboratory alone.

The entire laboratory covers an area of ​​more than 8,000 square meters and is divided into the first experimental area, the second experimental area, the third experimental area, the living area, the storage area, and the water and electricity control area.

There used to be more than 20 staff here, all of whom were temporary workers recruited by Li Qingye, including the school girl who helped with management. These people were all students from Jiangcheng University, Jiangcheng University of Technology, and Huazhong Agricultural University.

As for Li Qingye's own experimental area, the first experimental area, only he can enter.

Before returning this time, he asked Liu Xiaoli to dismiss the temporary workers in the laboratory, leaving only two security guards.

At this time, he was the only one left in the entire laboratory.

After opening the combination lock of the first experimental area, Li Qingye looked at the rows of test tubes in the freezer storage box. 17 wood-building factors (the enzyme he synthesized before) were displayed intact among them.

Closing the storage box again, he opened the hard drive in the safe and inserted it into the physically isolated desktop computer.

Re-read the experimental data of the wood factor.

After more than half a year of research, the wood-building factor at this time has actually developed into the second generation. He borrowed part of the [CRISPR-Cas9] gene editor technology to improve the controllable performance of the wood-building factor.

CRISPR-Cas9 is a gene editing technology that has emerged in recent years. It can accurately knock out target gene fragments and insert specified gene fragments into gene sequences.

Li Qingye borrowed the CRISPR part of CRISPR-Cas9, which is a special RNA gene sequence that can be combined with a specified DNA sequence.

The second-generation technology of Jianmu Factor is "CRISPR-JM", which can turn the specified gene sequence into a pseudogene (that is, lose its function).

According to another of his previous discoveries, that is, there are some "restrictor" gene sequences in human gene sequences. Through the insertion of building blocks, these restrictor gene sequences can be disabled.

After unlocking the limiter, you can gain a lot of abilities, but it also comes with huge risks. The domestic pigs and mice used in his experiments are an obvious example.

Although the side effects of domestic pigs and mice have decreased in several subsequent experiments, the cost is still very high.

After re-reading the experimental data, Li Qingye knew very well that with his talent, if he had more than ten years to accumulate it, he might be able to develop a safer and more controllable wood-building factor.

It's just that he doesn't have time.

It took three days to reconstitute the Jianmu Factor that was enough for one person, and also prepared a life-sustaining nutrient solution and experimental bed. Yesterday, I even took laxatives to empty out the contents of my stomach.

Lie on the bed, insert the urinary catheter yourself, and prepare a large bucket to connect the urinary catheter.

The heartbeat, blood pressure, body temperature and other detection equipment are also connected one by one, and then the cardiopulmonary resuscitation electrodes are connected to the heart position, and the cardiopulmonary resuscitation machine is automatically started 30 seconds after cardiac arrest.

A large hanging bottle (homemade) of special nutrient solution is inserted into the vein. This bottle of nutrient solution is enough to sustain life for 15 days.

Close the oxygen mask, press the switches of all equipment, and check all equipment again.

Before that, he also ordered the two security guards, Mr. Wang, to pay attention to water and electricity. If there was a sudden power outage, they would immediately start the backup diesel generator.

At the same time, he told the two of them that he was going to do an experiment for half a month and that he would not see anyone and not disturb him.

After adding a bonus of 3,000, Lao Wang and his wife also asked their wives to work together to take care of the gate, water and electricity.

In the laboratory.

Li Qingye looked at the Jianmu Factor that had just been thawed, abandoned all scruples, and inserted the needle into the vein of the other hand.

Drops of liquid containing the wood-building factor penetrated Li Qingye's whole body over time.

CRISPR molecules, which are RNA fragments, pass through the cell membrane, come to the nucleus, and then to the chromosomes, where they are combined with a specific gene sequence in the chromosomes.

The moment CRISPR is combined with human genes, the building blocks carried by CRISPR begin to play their role.

The limiter in Li Qingye's genes was damaged.

However, biological genes are extremely stubborn. After being damaged, the limiter gene activates its self-repair function.

It's just the presence of the building blocks that disturbed the self-repair of the limiter gene sequences. Although the genes were repaired, these gene sequences had lost their original functions.

In Li Qingye's genes, countless recessive genes became active.

17 hours later.

"Ahh..." This body seemed to have entered a furnace. He saw that his body temperature had reached 39.5 degrees Celsius. This was a clinical symptom of the explosion of inflammatory factors in the body.

Quickly insert hormone and antibiotic injections.

Soon he felt dizzy, his breathing became more rapid, and his blood sugar dropped rapidly.

Fortunately, the life-sustaining nutrient solution prepared earlier was continuously providing nutrients and energy, otherwise he might have been consumed to death.

The high fever, dizziness, and tingling all over my body lasted for two days and two nights.

At the foot of the bed, a dozen empty syringes after use were lying in a mess on the floor.

Suddenly Li Qingye's heartbeat stopped.
