The narrative of the healing story only took a few strokes, but in reality, from the start of the reaction to the generation of the substance, it took more than three days.

This speed is considered fast in the field of synthesis. Some more complex reactions require hundreds of hours of observation. A project team of over a hundred people spent four to five months just to produce a few milligrams of the final product.

The entire process, with even the slightest mistake, could be rendered useless.

This is the risk of biochemistry, but it is also its charm.

After confirming that the fourth-generation pyrrolidine - or the new cyclic compound - could be prepared conventionally, Xu Yun immediately instructed Qiu Sheng to be responsible for data collection.

He himself left the laboratory, took out his phone in the corridor, and dialed a number.

After a moment, a female voice came from the receiver:

"Hello? Who is this?"

"Jia Jia, it's me, Xu Yun."

"Oh, little Xu, what's up?"

"Well, Jia Jia, these days I've been conducting an experiment on cockroach repellent. Can I borrow some cockroaches from your insect laboratory?"

"No problem, how many do you need? When can you come to pick them up?"

Xu Yun thought for a moment and said:

"Three hundred Dubia roaches, five hundred Oriental cockroaches, German cockroaches, and American cockroaches each. As for the time... are you available now?"

After a moment, a smooth reply came from the other end of the phone:

"Eighteen hundred, right? Okay, I'll prepare them for you now. Come and pick them up."

After hanging up the phone, Xu Yun breathed a sigh of relief, took the elevator out of the medical center building, and headed towards the western area.

The western area of the University of Science and Technology was undoubtedly the area with the most cutting-edge laboratories apart from the Science Island, and it was incredibly mysterious.

Many people who didn't understand the University of Science and Technology would often wonder:

Why doesn't the University of Science and Technology have several national key laboratories, but many of its majors are still ranked so high?

The reason is simple. The University of Science and Technology has two national laboratories (actually, it should be considered two and a half now, as for the half, you can search it yourself), which is unparalleled among all universities.

What does this mean? To put it bluntly, one national laboratory is equivalent to more than ten national key laboratories.

So this is also a magical aspect of the University of Science and Technology:

Including the upcoming national laboratories, there are only twenty in total, but the University of Science and Technology occupies two of them, and it's about to have three. On the other hand, there are over three hundred national key laboratories in the country, but the University of Science and Technology only has two...

Among them, the well-known National Synchrotron Radiation Laboratory is located in the western area of the University of Science and Technology. It is also the first national laboratory in the country and holds significant meaning and status.

Synchrotron radiation is also one of the bases that truly fulfills the functions of a national laboratory among the current six major bases. The remaining micro-scale base is a bit chilly, and the Quantum Information Laboratory is still under preparation, but judging from the achievements of recent years, its future is undoubtedly promising.

In addition to various physics laboratories or research institutes, there are also some lesser-known small laboratories or research institutes in the western area.

For example, at this moment, in front of Xu Yun...

The Insect Research Institute.

This Insect Research Institute is affiliated with the School of Life Sciences. The building has only three floors, and there are more than twenty researchers divided into six research directions.

After presenting the access code, Xu Yun walked familiarly to a reception room.

After a few minutes, a girl in a white lab coat with a ponytail walked in:

"Xiao Xu? You're here?"

Xu Yun quickly stood up and greeted her with a smile:

"Jia Jia, long time no see."

The girl's name is He Jiajia, a senior fellow in Xu Yun's major. She is 27 years old and serves as an associate researcher in the Insect Research Institute.

He Jiajia was one of the people who introduced Xu Yun to the penguin group that protected the hairline.

After seeing Xu Yun, He Jiajia handed him a few closed suitcases with light-shielding measures:

"Here, the cockroaches you wanted are all here, exactly eighteen hundred."

By the way, why does our genius Xu have the leisure to work on cockroach repellent? Did Furong Amine have a breakthrough?"

Xu Yun took the suitcases and shook his head at the same time:

"It's not Furong Amine, it's Pyrrolidine."

"Pyrrolidine?"

Xu Yun nodded lightly:

"Yes, Pyrrolidine. But I can't explain the specific situation in a few words. I might publish a paper or something in a while. Jia Jia, you can pay attention to it then."

"What journal? Metallomics?"

"It's hard to say. I'll try to get it into the third zone."

Xu Yun didn't set too high of a goal for himself. After a brief conversation with He Jiajia, he said goodbye and left.

After leaving the Insect Research Institute, he returned to the laboratory with the suitcase full of cockroaches and reunited with Qiu Sheng and the others.

With the assistance of Li Yi and the others, they divided the thousands of cockroaches into more than twenty culture dishes.

He Jiajia thoughtfully classified the cockroaches by gender based on their race, with a female-to-male ratio of about 1:4, with fewer females and more males.

The cockroaches Xu Yun brought back this time were divided into four species:

Dubia roaches, Oriental cockroaches, German cockroaches, and American cockroaches.

Dubia roaches were mainly used as pet food and had similar properties to cherry roaches.

Many enthusiasts of spiders, centipedes, shoes, and ants would choose either Dubia roaches or mealworms for long-term feeding.

The remaining Oriental cockroaches, German cockroaches, and American cockroaches were common cockroach species in the country.The German cockroach is commonly found in the north, while the American cockroach is more prevalent in the south.

The legendary southern cockroach that is said to fly towards your mouth, with even its leg hairs clearly visible, refers to the American cockroach.

Xu Yun looked at the cockroaches crawling in the ecological box, his face unusually shadowed.

Then he turned to Li Ying on the side, took a deep breath, and said:

"Li, prepare the test drug!"

The early morning of the 1st, which is right after 12 o'clock on Friday night, will be the release time......

Dear book friends and bosses, are you ready?
