In the previous 1665 copies, there was a prominent hint in the formula for the fifth generation pyrrole insecticide that Xu Yun obtained:

[This is a good thing, but it's not so easy to master].

Therefore, the entire formula is not a foolproof one-click operation guide. It only provides some directions and structural expression diagrams. There are many aspects that Xu Yun needs to figure out himself, such as the pheromones from before and the targeted combination between the fourth and fifth generations.

In simpler terms...

You can't gain something for nothing.

However, compared to the breakthrough in the ring formation from the third to the fourth generation, the difficulty of the breakthrough from the fourth to the fifth generation is undoubtedly much smaller, meaning the span is relatively not as great.

The fourth generation determines the structure, while the fifth generation supplements the function. The former is the key step for a qualitative change.

Therefore, after establishing the direction for the optimization of the fifth generation, Xu Yun assigned the next stage of tasks:

"Lao Qiu, you will be responsible for the research and development of same-sex attractants with Xiao Tang and Xiao Li. The derivation of the sodium ion channel receptor binding will be left to me. Let's keep in touch.

There are many existing examples in the same-sex attractant biosphere. The key lies in the conformational changes of the sensing structural domain, which is not particularly difficult to operate. So let's set a time.

The laboratory can be used for another nine days, so let's aim for six days... Break through the attractant barrier within six days!"

Upon hearing this, Qiu Sheng and Li Yi exchanged glances and nodded heavily:

"Lao Xu, don't worry, leave it to us."

After assigning the tasks to Qiu Sheng, Xu Yun tidied up the materials and left the laboratory in casual clothes.

I'm sure classmates who haven't been driven crazy by the biology teacher should know.

There is a channel on the membrane of all animals that allows a small amount of Na ions to enter the cells along its electrochemical gradient, which is the sodium ion channel.

It was discovered by British scientists Hodgkin and Huxley and can be divided into voltage-gated and ligand-gated types.

The sodium ion channel is the main initiator of electrical signals in all animals, and electrical signals are the basis for controlling a series of physiological processes such as neural activity and muscle contraction.

Therefore, if the inactivation and deactivation of insect sodium ion channels can be regulated, prolonging the transmembrane sodium ion flow time and causing neural excitability conduction disorders, it can also accelerate the killing of insects.

According to the task assignment just now, the derivation task of the sodium ion channel receptor binding will be solved by Xu Yun alone. This is not an easy task, so he planned to go to the West District Library to look up some information first.

However, just as he left the medical center, his phone in his pocket vibrated.

"If I can make it before it gets dark, I will dig out your eyes~~~"

Xu Yun took out his phone and saw that the caller ID was marked with a number:

Pan Shuai.

Xu Yun's heart trembled when he saw this, and he quickly pressed the answer button:

"Director Pan, are you looking for me?"

A few seconds later, a strong male voice came from the other end of the phone:

"Yes, it's me, Xiao Xu, where are you?"

"I'm in the central area, at the medical center. I'm planning to go to the West District Library to look up something."

"That's a coincidence. I just came out of the same radiation laboratory. Shall we meet at the entrance of the library?"

"Sure, please wait a moment. I'll be there soon!"

After hanging up the phone, Xu Yun didn't dare to delay and quickly took a taxi to the West District.

More than ten minutes later, Xu Yun arrived at the entrance of the West District AED with a small bag.

At this moment, he saw a figure standing at the entrance of the library that he was very familiar with.

This person appeared to be in his fifties, with a kind face and bright eyes. He had a fringe of bangs slanting from left to right on his forehead and wore a pair of brown-framed glasses.

He wasn't tall, but his back was extremely majestic.

This person was Xu Yun's other mentor, the first person in domestic quantum communication, Academician Pan Shuai.

Xu Yun walked quickly to the person's side and greeted him:

"Teacher, are you looking for me?"

"Oh, Xiao Xu is here."

Academician Pan turned around and nodded to Xu Yun, casually patting his shoulder and pointing to the side:

"Let's walk and talk."

Xu Yun obediently followed.

Perhaps because the School of Life Sciences was located here, the greening measures in the West District of the university were quite well done. Tree-lined paths could be seen everywhere.

Not long ago, the West Lake, one of the attractions in the West District, introduced six black swans from a breeding base in Ludong. The natural environment here was more coordinated than the other two campuses.

Xu Yun and Academician Pan casually walked on a shaded path. After a while, Academician Pan took the lead in starting the conversation:

"Xiao Xu, your Ph.D. defense should be coming up soon, right?"

Xu Yun plucked a withered leaf from his shoulder and replied:

Theft is never good, try looking at [ pawℝead.com ].

"It's coming soon. Originally, it was scheduled for May next year, but Tian Dao helped me move it to March next year. It should be in mid-March."

Upon hearing this, Academician Pan nodded thoughtfully.

The time for in-service graduate defense in China is generally in December, while full-time students usually have it in May or June. However, there are occasional exceptions for direct Ph.D. students, who can have their defense in March. He continued to ask:

"Xiao Xu, I remember your academic papers in biology have already been published, right?"

Xu Yun made a sound of agreement and smiled:

"Yes, I published five SCI papers last year, but only two of them are truly valuable. One of them barely made it to the second zone."

"That's still very good."

Academician Pan praised and stopped, looking at Xu Yun seriously:

"So, Xiao Xu, for the next half year... are you interested in helping me?""Director Pan, is the school planning something big?"

As a physics graduate student, it was common for Xu Yun to be called upon to assist Director Pan or other big shots. If it was just a simple, ordinary research topic, Director Pan wouldn't have asked the question above.

Therefore, it was clear that the research project Director Pan wanted him to assist with must be a large-scale one with astonishingly high standards, so strict that it required Director Pan to conduct a 'interview' himself!

In response to Xu Yun's confusion, Director Pan nodded slightly:

"That's right. Recently, we've made some technological breakthroughs in a... um, certain field, so we're preparing to launch a new project."

Xu Yun looked at him curiously:

"Director Pan, can you tell me what the project is? Of course, if even the name is confidential, then forget I asked."

"It's not that serious. I can tell you the name. After all, the technology is the core."

Director Pan waved his hand with a confident smile:

"If all goes well, we're about to conduct a fifteen-photon entanglement experiment!"
