After a busy day in the laboratory, after getting off work in the evening, Ye Zhenzhen took the central shuttle bus back to the Xincheng apartment.

Downstairs of the Xincheng apartment is a row of commercial streets, which have shops selling Beijing specialties, Ye Zhenzhen walked into a good and cheap one, selected a few special products, and prepared to take them back to her hometown during the Spring Festival.

Coming out of the specialty store, I saw You Kexin standing downstairs from a distance, holding hands with a man, the two of them had smiles on their faces, Ye Zhenzhen stopped suddenly, now at this time, it's better not to step forward to make light bulbs.

The young man next to You Kexin is very familiar, it is Liang Ji's boss, Liang Chen, who has been helping Liang Chen for the Tuanshan Forum in the past few days, Ye Zhenzhen smiled and muttered: "The two of them have finally passed the budding period of love, and the relationship should be exposed to the sun openly." ”

Ye Zhenzhen stood at the door of the shop, watching You Kexin and Liang Chen hold hands and hug goodbye, until Liang Chen drove a red sports car and left the Xincheng apartment, You Kexin reluctantly turned around and walked back.

Walk a few steps quickly behind You Kexin, Kexin was still immersed in the atmosphere of love just now, and without noticing, Ye Zhenzhen patted Kexin's shoulder from behind, "Hey, Kexin, what's the daze?"

"Ah, scare me!"

Hearing Ye Zhenzhen's voice, You Kexin was indeed taken aback, clutching her chest and asking, "Zhenzhen, when did you come over?"

"From the time you and Liang Chen went downstairs, holding hands, hugging, and kissing goodbye...... Tell me about it, when did it start? ”

"Okay, okay, don't talk about it, I'll explain, it's the most recent thing, last week, Brother Chen confessed to me, I ...... I promised him, I wanted to tell you, but before I could do it, I was bumped into by you. You Kexin's face is shy, which is a unique expression of a girl in love.

"Congratulations, I knew that the two of you would become a couple, but your nickname of 'Brother Chen' is really numb!" Ye Zhenzhen joked with a smile.

You Kexin was not annoyed, and pulled Ye Zhenzhen to the elevator door, "What about me, I heard Senior Sister Su Wanru say that when you were in Paris, you called Nanda God 'Senior Brother Qiao', which is comparable to my family's 'Brother Chen'." ”

"What? Senior Sister Wanru actually told you this, didn't she say anything else?" Ye Zhenzhen was worried that her troubles in Paris would be shaken out by Su Wanru.

"Other things, doing foundation work, the oolong terrorist attack, or the fact that you were in a coma and hospitalized? Or is it the thing that you fell into Henan and the great god gave you artificial respiration?"

Ye Zhenzhen blushed, and complained in her heart, this Senior Sister Wanru said that she would keep it secret, but she still told Kexin.

When it was said that there was something wrong, Ye Zhenzhen hurriedly changed the topic and asked, "Kexin, the Spring Festival is coming soon, when are you going to go home?"

You Kexin instantly made a stinky face and complained: "I can't go back this year, I have to work overtime!"

"Huh, does Nanmu Group squeeze employees like this?"

"Not really. You Kexin pulled Ye Zhenzhen into the elevator, sighed, and said: "Our stem cell research group, there has been a sudden new development recently, everyone has to work overtime, and the salary during the holiday is five times the usual." ”

You Kexin stretched out his palm, and five fingers shook in front of Ye Zhenzhen, Ye Zhenzhen smiled and asked, "Are you reluctant to pay five times the salary?" ”

"Yes, five times the salary, the seven-day holiday during the Spring Festival, is the usual one-month salary, anyone will be tempted, but ......" You Kexin deliberately paused, leaned into Ye Zhenzhen's ear, and whispered: "The reason why I stayed to work overtime is that I am more curious about the research progress of our stem cell research group this time." ”

"What's going on?"

As soon as Ye Zhenzhen finished asking, the elevator door opened with a "ding", and You Kexin pulled Zhen Zhen out of the elevator, and whispered while walking towards the door of the rental house: "Let's go back to the house and say, this should be kept secret." ”

Opening the door of the rental apartment, You Kexin pulled Zhen Zhen to her room, closed the door, and took out her mobile phone.

Looking at Ke Xin's series of actions in surprise, Ye Zhenzhen asked with a smile: "Ke Xin, what are you doing, mysterious and secretive." ”

You Kexin pulled up a photo from his mobile phone and handed it to Ye Zhenzhen, "Look at this photo, it is related to the progress of the Nanmu Group Stem Cell Research Center. ”

Ye Zhenzhen took Kexin's mobile phone, in the photo of the mobile phone, an experimental mouse has a person's ear on the back, "This is an experiment of cross-species transplantation of human cartilage tissue, a few years ago, the director of a hospital in Shanghai, it seems that a professor surnamed Cao did this research, and published a lot of related articles, what's the matter?

You Kexin shook his head mysteriously, pointed to his phone, and said, "Keep looking, our research group is not only studying this. ”

Touching the screen of the phone with his finger, the photo changes, and on the back of a large rat with bare skin, a black mass of tissue resembling human hair grows.

Staring at the junction between the black hair and the skin on the back of the mouse in the photo, the hair and the skin blend together perfectly, Ye Zhenzhen sighed lightly, "How did these hairs be transplanted? ”

You Kexin shook his head again, "It's not a transplant. ”

"It's not a transplant? How is this possible?" Ye Zhenzhen did not believe that without a transplant, hair tissue would grow on the back of a rat, and even if the gene was changed, such an effect would not occur.

You Kexin mysteriously pointed to his phone, "Look down." ”

Swiping the screen again, another photo is even more eerie, with a white eyeball on the back of a bare-skinned mouse with a round black dot on the eyeball, and a dilated pupil in the center of the black dot.

Continue to swipe the screen, each experimental rat has different human organs, hands, feet, skin, muscles, bones......

Ye Zhenzhen was speechless in surprise, so many human tissues can grow on the back of a mouse, and every organ is perfectly integrated with the experimental mouse!

"How did you do that? Kexin, are you sure these photos are not photoshopped?"

You Kexin pointed to his eyes, "I saw it with my own eyes, I took it with my own hands, in the experimental building of our Nanmu Group Stem Cell Research Center, in the rodent laboratory on the fourth floor of the basement, this is top secret, Zhen Zhen, you must not say it, otherwise, my job will be gone, and I may be held accountable." ”

Ye Zhenzhen nodded, "Well, I won't say it, but how did you do it, if this technology is applied to the clinic, it will be a revolutionary breakthrough, which organ is broken, transplant a new organ." But are you sure this is not an adult organ collected from the human body and transplanted into the back of a mouse?"

"I'm sure it's not a transplanted organ, show you a few more pictures, and you'll understand. ”
