The middle-aged man continued, "This is a study conducted by our Odenko Biopharmaceutical Company, the source cell can form cells with the same environment in a specific cellular environment, but the genetic material in the source cell will tend to be stable after division and transformation, and there will be no mutation, unless it is under strong external environmental intervention. ”

Lu Ruihe listened very carefully, but the middle-aged man didn't seem to want to say anything, he propped up the podium with both hands, "What else?" ”

"How to activate this source cell is the most critical point, but many experiments have failed!"

"Yes! The nature of the source cell itself is that of a dormant cell, which divides and multiplies entirely due to its distinctive genes. ”

The more he spoke, the more excited he became, "So... ”

"I'm sorry, that's all I can say, any more, I'll break the non-disclosure agreement, and Odenko won't let me go!"

Lu Ruihe only remembered now that the middle-aged man had said that he was an employee of Osdenco Biopharmaceuticals! I really can't imagine that this company has been doing research on this aspect, so I was worried about the kind of people in the living area who thought that I was giving up biotechnology, was it too much for me to worry!

He thought about it, why did this middle-aged man come to the school and listen to my class, logically speaking, the content of my class is completely out of line with their company's research, only the project he said is slightly related, could it be that he came to invite me!

Thinking of this, Lu Ruihe's heart suddenly became happy, he felt that his opportunity might come, and this was also something he was interested in.

"What is the purpose of your visit, this friend?"

"A few questions for you."

"About the evolution of mutant organisms?"

"It's about mutant creatures!"

Lu Ruihe's heart was excited, but the words that followed extinguished the fire that had already ignited in his heart.

"But it's not evolution, it's about some questions about the inside of the bodies of mutant creatures."

The middle-aged man stood up, put his pen in his notebook, and walked towards Lu Ruihe, "Do you know pheromones?" ”

"Yes!"

"Can you tell me specific information about pheromones, then?"

The frustration on Lu Ruihe's face was taken away a little, although it was much different from what he thought, but someone asked for advice, which still made the disappointment in his heart a little less, "You want to know what kind of pheromone knowledge." ”

"How pheromones work, and the specific range, and how to identify them, and whether they can be synthesized artificially."

Lu Ruihe raised his glasses, "I can tell you the rest accurately, but if you synthesize it artificially, it will be quite difficult, you must know that there are many types of pheromones, only if you know the molecular structure, you can synthesize according to this structure, even if it is synthesized, the cumbersome process will cause a certain amount of loss, and there may only be half of the finished product." ”

"That's not what I'm thinking about!"

"How does your company need to know this information, and the company should have relevant knowledge materials in this area!"

"Can you answer my question?"

"Huh! Good! Lu Ruihe didn't expect the middle-aged man's tone to be so straightforward, and he didn't seem to want to tell him anything else at all.

He told the middle-aged man the specific information of pheromones, which suddenly made him feel like he was back in the old days, when students had a strong desire to learn.

And the middle-aged man did not return to his position, he put his hand on his chin, stared at the information written on the blackboard, and at the same time asked different questions in time,

His questions are always so timely, and they point to the point at once.

It has been a long time since he has met such a student, Lu Ruihe is quite relieved in his heart, although the middle-aged man in front of him is not a student at all, but it still makes him feel the passion of educating students in the past.

"The pheromones of the symbiotic relationship must be the closest chemical substance between the two mutated organisms, with the same characteristics, and can be identified by the two mutated organisms."

"What's that most likely aspect? Suppose an organ of an organism is the source of pheromone production! ”

"For example..." The middle-aged man pointed at him and wanted him to give an example.

Lu Ruihe thought for a moment, and when he was about to speak, the middle-aged man spoke first, "Such as a poison sac!" ”

"Poison sac!" The middle-aged man pondered for a moment, "Oh! Then it can be deduced that the mutant creatures with which they have a symbiotic relationship also have organs similar to poison sacs in their bodies! ”

"Yes!"

"If it's an insect, then..."

Lu Ruihe quickly responded, "It's probably the venom gland in the insect's body!" Mixing the two organs produces pheromones that attract both sides. ”

"Proportions!"

Lu Ruihe frowned, "This needs to be tried slowly, because every mutant creature is different. ”

"I need to know the approximate proportions."

"This!" Lu Ruihe knocked on the table with his hand, his whole face wrinkled, he wanted to tell the other party, he didn't know, but the person's appearance looked quite urgent, and the previous good impression also made him feel a responsibility to inform the other party.

He thought about it for a long time, because it was not easy to be sure, and finally he gave an answer, which he was not very satisfied with, "about twenty to forty percent." ”

"The span is a bit big!"

"Sorry, I can't help it, because I can't really go into detail about this situation! Although it has been studied before, there are so many types that I can only give an approximation. ”

"Thank you!" The middle-aged man got up directly and walked towards the door.

Lu Ruihe didn't expect this person to leave directly like this, which made him feel quite disappointed, it turned out that he didn't come to invite me, and yes, after so many years of education work, such a big biopharmaceutical company can't look down on it! Besides, the old ones have long been forgotten!

Nothing! He tried to comfort himself in his heart.

Lu Ruihe picked up the books and materials, and when he was about to leave, he saw the notebook that the middle-aged man had left on the desk.

How did this guy forget about this! He hurriedly walked up, picked up the notebook, and quickly left the classroom towards the stairs, and through the gap between the stairs, he saw that the familiar figure was walking down the handrail.

"You didn't take your notebook!" Lu Ruihe shouted downward.
