It took three days for the first phase of the experiment team to finally locate the allergen. As Lin Qing expected, the problem was indeed on the injection needle.

But strangely, the chains that cause allergies by needles are extremely rare. The final metal analysis results show that all of these mice are allergic to trace copper elements.

In other words, this batch of needles contains copper.

This is not a fussy exception, because the stainless steel used in the syringe originally contains a small amount of copper, but the problem is that in the few seconds of brief contact, these copper elements are basically not likely to cause allergies.

So, the only possibility is that this syringe contains free copper elements.

After further analysis, the experimental team came to an unexpected conclusion:

The needle carries trace amounts of copper powder, which should be contaminated during the production process. The cleaning process of the experimental group cannot completely remove the copper ions adsorbed on the surface, which eventually led to allergies in some mice.

"...Isn't this nonsense? After searching, I finally found out such a result?"

Xuan Cheng had no choice but to listen to Lin Qing's report. He really didn't expect that allergens would come from such places.

"It is indeed an extremely small probability event - it is not a big problem. If this batch of needles are used in clinical practice, it may not be possible to find them at all."

"But since the manufacturer has such a problem, I suggest that the purchase should be suspended and let them check it themselves first, and then use the manufacturer's products for subsequent experiments."

It was confirmed that it was not a problem with the experimental process and technical documents, and Lin Qing's tense spirit also relaxed.

After eliminating this deviation, the entire zero-stage experiment can be declared successful.

After a few simple words, Xuan Cheng signed the investigation report, and the report was handed over to the General Technical Office along with the experimental results.

For the zero-stage experimental team, their work has been completed.

However, they did not expect that this report would cause a huge storm in the near future.

...

Two weeks later, in the building of the BCI Research Institute of Zhejiang University, Suzhou and Hangzhou.

After several months of treatment, Yaoyao's condition has basically stabilized. For the sake of promoting recovery, she was allowed to be discharged from the hospital and returned home - of course, she was actually returning to the BCI Institute.

Under Chen Li's application, Yang Yiyao and his sisters had moved from their original shantytown to the dormitory of Zhejiang University and lived next door with Chu Ya, which made it relatively convenient for both life and work.

Now the bcl transmission project is being launched on a large scale. As the first and the best experimentalist with the adaptability so far, Yaoyao still needs to provide a large number of optimization experiments in the project and output optimization suggestions based on her personal experience.

Before she got sick, she could be said to be the absolute core member of the project. Even after she stopped participating in the project, the experimental team fell into a brief chaos.

However, such chaos is not necessarily a bad thing.

To a certain extent, getting rid of the dependence on individual experimenters has driven the project to develop in a truly universal direction.

So when Yaoyao was discharged from the hospital and returned to the institute to prepare to return to her position, she was still lost for a while.

Because of its position, it has been replaced by a new cross-experiment group.

Most of the time, all she needs to do is just some data verification work. After all, no one in the entire research institute can be faster than her.

This day was another boring day. Yaoyao sat bored in Chen Li's office. It seemed that there was a report on the difference in nerve electrode feedback rate on the table. She had read the data above no less than five times and had already reached a conclusion, but she did not hand over the results to the experimental team.

The reason is very simple. Once this report is submitted, it means that my day's work is over again.

Why not continue to take a look? What if there is any problem you haven’t found yet?

So she turned the thick report back to the beginning, and looked at the first number, compared the data as standard reference value one by one, trying to find an abnormal fluctuation point.

But this kind of work is really boring, just stick to it

After a while, she lay on the table.

Just at this moment, Chen Li pushed open the door and walked in.

He saw Yaoyao lying on the desk at a glance, and hurriedly walked up to ask:

"What's wrong? Yaoyao is sleepy?"

Yaoyao frowned and raised her head, answering:

"It's not that I'm sleepy, it's too boring. Brother Chen Li, can you arrange some other jobs for me? These things are so simple."

"You know, I can do a lot of things for you, it's a waste to just do these..."

Chen Li breathed a sigh of relief and replied with a smile:

"This is not a question of whether to waste or not. You are still sick now, so you should focus on rest..."

"But I've really had enough rest."

Yaoyao interrupted Chen Li's nagging aggrievedly. Seeing her expression, Chen Li smiled knowingly.

She was probably really bored and cruel.

Think about it, a child of her age is either going to school or playing wildly, what about her?

There is no need to learn basic content, and there is little contact with peers.

After getting used to the rhythm of participating in scientific research projects, I suddenly had nothing to do. How can I not be bored?

However, saying that, he did not plan to arrange a new job for Yaoyao, but instead completely removed her from the project team and re-entered the resting period.

"You haven't had enough rest yet."

"From tomorrow, you don't want to come to the institute. There will be a nurse and sister accompanying you to monitor your physical condition. She will tell you when to rest and when to exercise."

"I don't want it...hey?"

Yaoyao subconsciously wanted to refuse, but in an instant, she keenly discovered the problem.

Why did you suddenly let yourself go back and rest?

The doctor told himself before that it doesn’t matter if he works moderately.

The answer seems to be very obvious.

"I'm going to have surgery?"

Chen Li nodded, his reaction to Yaoyao was not surprising.

"When?"

"It's probably in next month - about two weeks later, you have to go for some tolerance tests first, which is why you need to go home and rest."

"If this operation is successful, your disease will be completely cured."

"Okay!"

Yaoyao suddenly stood up from the chair without hiding her excitement.

No one is willing to live with the disease, even if it is just a small cold, everyone wants to cure it immediately.

Not to mention a life-threatening disease like lupus erythematosus that may break out at any time.

She walked around the room excitedly, but suddenly, she turned to Chen Li and asked:

"It must be me?"

Chen Li was stunned for a moment, and soon, he also understood what Yaoyao meant.

After hesitating for a moment, he shook his head and replied:

"Not necessarily, I'll help you ask Uncle Ye. If he agrees, you can decide for yourself."

"But maybe not - there are so many opportunities, not only this opportunity."

Yaoyao nodded and said:

"I know."

"However, I can wait for the opportunity in the future, but some people can't wait."
Chapter completed!
