If the gene bank at the medical university is not big enough, then go to the research institute.

The Institute's gene bank is one of the largest in the universe, covering data on almost all races and combinations.

Ace pinched the bridge of his nose while sitting in his office.

Fortunately, during the last two susceptible periods, Ace didn't seem to be too averse to Slov. I don't know if he was just used to it.

Cheng Yu lay on the table, reading a book with some boredom.

Recently he likes reading paper books with Ace.

I don't know where this book came from, but it looks very historical. It's full of professional terms, which is very hypnotic to Cheng Yu.

Bai Yan went out early in the morning, and Cheng Yu didn't go with him because he was still sleepy. However, he couldn't sleep after Bai Yan left, and he didn't want to stay in bed, so he simply came to stay with Ace.

"Ace~" Ace looked up at Cheng Yu who was sitting at the table.

Cheng Yu pointed to a place in the book, and stared at Ace with puzzled eyes, wanting him to explain it to her.

He turned the book around and handed it to Ace.

Alpha and alpha, pheromone submission?

Ace quickly took the book, his brows furrowed slightly.

Pheromone submission is an extremely rare phenomenon that usually occurs between highly compatible individuals.

Due to the particularity of the genetic structure, the pheromones of one party will produce a non-compulsory but irresistible attraction to the other party, and may even cause the other party to subconsciously cooperate and become dependent on the other party.

Ace looked at this and was slightly stunned.

"My dear, where did you find this book?" Ace opened the cover and found that it was a book written over a hundred years ago.

Cheng Yu thought about it.

This is what he picked up casually. "In the warehouse."

Bai Qinghan found it from the innermost part of the warehouse when he was sorting things out the day before yesterday.

Ace had never heard of the book, or even the author, at all.

Otherwise, with all his efforts over the years, it would be impossible for him to know about this word only now.

He lowered his head and flipped through the book, which described in detail some special cases and theories, including pheromone reactions between multiple highly compatible individuals, and the pheromone submission phenomenon that occurred in very rare cases.

Although these contents are highly theoretical, they are not supported by actual experimental data.

"Little ancestor, do you know the importance of this book?" Ace raised his head and looked at Cheng Yu, "You are really my god."

Ace was really excited. This was so important to him.

He scanned and archived the contents of the book, sorted out some key theories, and decided to use the book as a reference to re-examine his experimental direction.

Cheng Yu listened to Ace's words, just raised his eyes, with a slight smile in the corner of his eyes.

Ace put the book aside and lowered his head to start typing on the computer. He had already started planning the next experimental direction in his mind.

Cheng Yu didn't disturb him, but just lay quietly on the table and looked at him, occasionally turning a page of the book, making a faint rustling sound.

Over the next few days, Ace incorporated the theories in the book into his own research.

The more he studied it, the more he felt that the "pheromone submission" theory proposed in this book was very likely to exist in reality.

Not to mention the last time Slov nibbled his own gland during his susceptible period, but he did not experience a pheromone outburst.

But he couldn't handle this matter alone, he needed help.

The first person he thought of was Rona. Although Rona had not appeared in the medical field for many years, her academic acumen and in-depth understanding of genetic research were irreplaceable.

Ace called Rona's contact number several times and finally got a reply.

She looked very different from what he remembered, but she was still wearing a white coat.

"Ace?" Rona's puzzled voice came from the light brain.

"It's me." Ace was a little hesitant at this moment. He was worried that Rona would remember something bad.

"Ace? Is there any progress in the research?" Rona's voice was excited and a little anxious.

"Lorna, there's something I must tell you." Ace got straight to the point. "I found a possible theory in a book written over a hundred years ago - pheromone submission."

Ace quickly pulled up a page from the book and projected the content onto the computer screen. "Take a look at this."

Rona carefully read a few lines, her brows gradually furrowed. "Individuals with high compatibility will experience a non-coercive attraction between pheromones, and this may lead to a certain submission from one party to the other... Is there any experimental data to support this?"

"Not yet, but I have found some individual data with similar characteristics from the institute's gene bank. More importantly—" Ace paused, his eyes becoming more serious.

“I suspect this phenomenon may be happening to me.”

Rona looked up at him, a scrutinizing look in her eyes. "On you?"

Ace tells Rona about his experience.

"There is actually such a thing." Rona heard it for the first time. There are only two reasons why alphas are not accepted by the world when they are together.

One is the inability to conceive, and the other is the issue of pheromone mutual exclusivity. The former is a matter of personal choice, and not many people care about it.

If the pheromone mutual repulsion can be solved, then nothing will be a problem.

Ace had a long discussion with Rona and finally decided to use himself as the research subject.

In order to ensure the safety of the experiment, senior genetic experts from the Ace and Rona Joint Research Institute developed a detailed experimental plan.

They needed to extract samples from Ace's genes, as well as conduct a comprehensive analysis of his glands and pheromones.
