The portal quietly emerged next to the forbidden forest of the floating castle.

Trailers equipped with sleeping animals were pushed in by many staff members.

"Do I have to work here in the future..."

A female breeder walked out of the portal, looked at the deep Forbidden Forest, and turned to look at the magnificent castle complex in front of him, and was excited: "Do you want to live in the castle?"

"Congratulations on being selected." The colleague walked up and touched the keeper's face: "I can finally become a princess, not the kind in KTV."

Keeper: "…"

"There is a prince living in this castle." The colleague reached out and pointed at Chen Yu who was chatting and laughing with many leaders: "Listen to the sound, he is a sexy uncle. He is a little sexy hoof, seize the opportunity!"

At this time, the floating castle had reached the Pacific equator and its height was reduced to four kilometers.

But many animals cannot adapt to this altitude.

Helplessly, Chen Yu had to lower the height by another 1,000 meters.

Animals that were unable to adapt to were sent to several courtyards in the castle.

As for the two giant pandas that were "captured", they were arranged to the largest central courtyard. They were cared for by two keepers, and Hermione helped adjust the temperature.

After more than half an hour, everything was arranged.

After deciding dozens of ornamental birds, there were twenty-seven animals left in the floating island, which was not too many.

There are ten keepers, all of whom are working formal employees at the zoo.

It is considered the first batch of residents of the floating castle.

In addition, a leader who claimed to be in charge of zoo employees also tried his best to stay, saying that he could help Chen Yu "manage" the employees, and was kicked back to the capital by Chen Yu from the Pacific Ocean.

If you add dozens of animals to ten people, you will consume less food.

In order to avoid trouble, Chen Yu directly brought the zoo to live supplies for a month.

As for a month later... his plan had already begun to be implemented, so he didn't need to take care of the supply.

Saying goodbye to the official staff who kept talking endlessly, Chen Yu disconnected the portal and led ten keepers into the castle and came to a classical conference room.

Sitting in the first seat, Chen Yu pushed the mask and smiled: "First of all, you are welcome to officially join the big family of the floating castle. Don't applaud, listen to me."

Everyone quickly put down their hands.

"Among you, there are real breeders and special identities, I don't care about these. But since you join in as breeders, you must do your job well. After completing the work, just wander around the entire island as long as it is not destroyed."

As he said that, Chen Yu raised two fingers: "But there are two places, you can't get close to them. One, the principal's tower, the other, the library. As for where you live, Hermione will arrange dormitories for you."

"Finally, let's talk about the problem of animals. Under my experiment, they are currently in a benign fainting state. You should observe more and take notes."

"That's all I want to give, everyone applaud."

"Smack it..."

"After meeting!"

Waiting for the ten keepers to leave, Chen Yu looked at Hermione and asked about the serious matter: "Do you know some knowledge about the human body?"

"In addition to being a robot that assists the operation of the floating castle, I also loaded a parenting module." Hermione smiled: "Basic popular science is one of my responsibilities."

"What is the microorganism?"

"It is a special bacterial flora cultivated by humans at the end of the 21st century. It mainly plays a role in regulating the bacterial balance of the human body and preventing the occurrence of diseases."

While speaking, Hermione swung her staff and showed a set of dynamic pictures in the air, explaining in detail: "This is one of the greatest inventions of mankind. Its history can be traced back to 2003. After humans completed the genome project, they obtained sequencing of all human genes and understood the role and expression results of all human gene fragments."

"At that time, humans, including the academic community, did not realize the huge role of this plan. It can be said that the main support for human beings to build an increasingly prosperous civilization was this plan."

"Continue." Hearing the secrets about modernity and the future, Chen Yu's curiosity was immediately aroused.

"In 2003, after humans completed the genome project, they found that these genomes could not explain all the phenomena of human beings, and then they started the follow-up of the genome project, the Human Microbiome Project."

"In decades of research, humans have finally determined the truth that shocked the world."

"What's the truth?"

"Humans, the subject is actually composed of microorganisms." Hermione's tone was stable: "Although there was a similar statement in the biological world at the end of the 20th century, it was not finally confirmed until the beginning of the 21st century."

"There are 60 trillion cells in the human body, but the number of bacteria is close to 2000 trillion. They form a stable symbiotic relationship with the human body and control human physique, diseases, lifespan, and even habits and thinking."

"This...how is this possible?" Chen Yu was stunned.

"The simplest example. For example, some people like to eat beef, some like to eat sea fish, and some like to eat sweets. In the past, humans simply thought this was their own idea, but they did not know that these appetites were controlled by a part of the bacteria."

Hermione swung her staff and pointed to the flora in the virtual projection, continuing: "These flora produce various chemicals in the intestines, affecting the host's thinking logic, so that the host can only eat what they like and adapt to. For example, humans who often eat beef eat seafood once, which can easily cause intestinal flora to be unadapted. While 'torturing' the host, they stimulate biozymes, causing the host to feel disgusted with seafood."

"I like watching movies, playing games, playing sports, and I like a certain opposite sex..."

"Most of these so-called individual behaviors are the result of various bacterial groups and chemical reactions in the body."

"The personality changes found after many organ transplants have also been confirmed to be the acceptance of the changes in bacterial flora..."

"And this is just the tip of the iceberg of the impact of bacteria on the human body. With the deepening of research, humans gradually discovered that the so-called individuals are actually symbionts composed of bacteria, viruses, parasites and a small number of cells."

"This has caused a subversive revolution to the culture of human society. After medicine alone transfers its center of gravity from cells to microorganisms, many diseases, viruses, and cancer, that were originally terminally ill."

"The overall life span of human beings has also broken through the limits of telomeres with the help of various artificial flora. The accumulation and use of knowledge is more efficient, and civilization has begun a real technological explosion."

Turn off all projections, Hermione looked at Chen Yu to summarize.

"And microbial bacteria are one of the greatest artificial bacterial groups invented by humans."

"That……"

Chen Yu's eyes flashed: "When did the human microbiome plan you mentioned end?"

"It was led by the 2007 National Institute of Health (NIH), and participated by China, Japan, Britain and other countries. It was originally planned to be completed in 2025, but due to the breakthrough progress of the Chinese Academy of Sciences and Magic City Jiaotong University in 2021, the completion time will be four years ahead of schedule."

"2021? That is this year?" Chen Yu suddenly stood up.

"Yes. In 2019, the academic community recognized the dominant position of bacteria in the human body. The plan was officially completed in 2021, and the results began to be slowly applied to human society. In 2035, the first artificial bacterial species was successfully developed, and humans completely got rid of 90% of diseases."

"That is to say," Chen Yu instantly recalled the news he had seen: "Some professionals predicted on the Internet that a healthy vaccine can be given in the future..."

"It's the artificial flora." Hermione nodded.

"I see……"

"I see……"

From these points of time, I recalled the plan I was about to start, and an inexplicable coldness swept across Chen Yu's body...

...

(For plot needs, the achievements of the Academy of Sciences and Jiaotong University were delayed by several years.)
