It tells the story of BF, a biotechnology company that has ended the centuries-old relationship between human beings dominating and being dominated by food animals.During the period of rapid growth in the meat market, people inside and outside the company began to question the behavior of the BF representative.

BF successfully commercialized artificially cultivated meat for the first time in 2022. Global consumers have an overwhelming preference for BF meat products, and even successfully cultivated fur. BF showed investors and core figures at the 2025 press conference that human beings have an overwhelming preference for BF meat products.The cruelty of animals, killing and slaughtering, do you have to sacrifice animals if you want to enjoy meat?“BF was founded based on this problem 15 years ago. Now it has successfully achieved a market share of 72”. Yin Ziyi promises that the things on the table in the future will be more transparent and safer than before.This press conference is also an opportunity for Yin Ziyi to release a new product, which is to extend the territory to aquatic biological food (seafood), especially to remove toxic substances that harm the environment. It is neither bloody nor dangerous. In order to uphold the principle of saving the earth from destructionIn line with the principle, Yin Ziyi said that within six months, the goal is to produce even grains.

At this press conference, Yu Caiyun arrived as a distinguished guest. He also paid special attention to a few specific core figures in BF. Whenever Yu Caiyun looked at Yin Zili, he would think of what they had experienced in the past.A case of attack.Yin Zizi encountered a traffic jam on her way home. A man noticed Yin Ziyi's car, and then suddenly a man fell from the sky and fell on the roof of her car. Yu Caiyun happened to witness it while following Yin Ziyi, so he immediately went to the emergency scene.The current Prime Minister Xian Yuzai knew that the man who committed suicide was because his BF's relationship made it impossible for his original animal husbandry to survive, so he specifically targeted Yin Zili's car and originally planned to break Yin Zili's neck.Yin Ziyi discovered Yu Caiyun's figure through the driving recorder screen, and Hong Xinye said that the police felt that the insurance company might leak the moving route to the deceased, so they discussed whether to find a full-time insurance company.

Yin Ziyi felt that Yu Caiyun happened to be passing by and knew how to rescue, and Zheng Haiden seemed to have seen him somewhere. It all seemed just right. At this time, the news appeared on the news that BF meat was full of bacteria. 30 minutes ago, JinShen Jie went to the laboratory office and found that all the files had been encrypted, which meant that the computer had been hacked!The other party demanded 80 billion won in Bitcoin within two days to unlock it. Yin Ziyi found it strange how could only the laboratory be hacked?Zheng Haiden went to a journalist she knew to inquire about information, but the Ministry of Information felt that Zheng Haiden's reaction was a bit strange. After all, shouldn't she be trying to deny the rumors?Zheng Haiden believed that the murderer might have taken the opportunity to hack into the laboratory when no one was around when the new product was released. Yin Zili decided to resolve the matter privately and without publicity this time.

The Naval Intelligence Command was also attacked by hackers in 2022, but the truth was covered up by the government. Yin Ziyi suddenly discovered that Yu Caiyun served at the Intelligence Command from 2020 to 2023, so Yin Ziyi was considering whether to make good use of it.Yu Caiyun’s resource?The next day, former President Li Wenkui called in Yu Caiyun, whom he had not seen for many years. It turned out that Li Wenkui was the one who sent the invitation letter to the BF press conference to Yu Caiyun. He wanted to know if he had found the terrorist?In January 2024, Li Wenkui made a temporary decision to visit the overseas troops, so the VIPs on the plane followed Li Wenkui. As a result, an explosion occurred here. Li Wenkui suspected that Li Nanzhen, the president of STL, and Shanghe Group were not dead.Park Dae-sung, Han Ki-ho of Technology Game, and Yoon Zili of BF. After all, not even the army knew about Li Wen-kyu's itinerary, the only ones who knew about it were these VIPs.

Li Wenkui is suspicious of the remaining Yin Ziyi, because when he took office, Yin Ziyi asked him to stipulate a law to label cultured meat as genetically modified food, which also made him have to step down, even BF grew and succeeded significantly after the attack case, has a very good relationship with the current president, and he can be sure that Yin Zili is doing some illegal activities. Now only Yu Caiyun can get close to Yin Zili and find information, so Yu Caiyun was lured into BF by Li Wenkui., and asked him not to forget the shame brought about by the attack.

Yu Caiyun came to BF to accept various tests as a bidder, and Yu Caiyun performed excellently.When he came to Wenshan, Yu Caiyun knew that he had established BF with Yin Ziyi in the past. When BF was struggling, Wenshan devoted himself to the medical field and worked as a medical laboratory technician for three years. Even as a research director, he did not participate in BF.Activity.Yu Caiyun did not shy away from saying that he had investigated the backgrounds of Wen Shan and Yin Zi Zi, and specifically said that Yin Zi Zi is now the person who needs protection the most. Subsequent deployment of Yin Zi Zi said that after the investigation, no team member had used the external network.Road, so there is still no progress. What is even worse is that there is now a South American gang organization offering a bounty on Yin Zili's head. It is because BF's industry has restricted their original farm business that they are so resentful of Yin Zili. In this regard, Yin Zili isI had some awareness from the beginning.

Even when Yu Caiyun returned home, he was attacked by two men. The other party asked Yu Caiyun to reveal to them the time when Yin Free Association was alone, so that Yu Caiyun could ensure the safety of his wife and children, and also get a huge sum of money.It turned out that all this was Yin Ziyi's verification of Yu Caiyun. She had to really and thoroughly confirm whether Yu Caiyun could really be trusted (after all, there were too many coincidences before that were worthy of suspicion).It's just that the two were filled with tension as soon as they met. Yin Ziyi first expressed that Yu Caiyun's background was unusual, and Yu Caiyun also deliberately asked Yin Zizi what problems she had with the Intelligence Command.Yin Zilibai admitted that he wanted to ask how Citizen X dealt with the attack on the army before, but what he got was a desperate answer. No one could catch the other party.

Now after Yin Ziyi and Yu Caiyun discussed it, they believed that only by paying the ransom can the whereabouts of the gangsters be found and the files recovered. Yu Caiyun suggested that a report should be made quickly before government agencies could be invited to launch an international investigation. ThisLet Yin Ziyi struggle because if the public knew that it was a fact that the hacker was hacked, they would also think that the bacteria in the culture fluid were dug up by hackers. Yu Caiyun believes that the murderer cannot be caught now because everyone is afraid of this and is unwilling to do so.I'll investigate if I mention it again.Xian Yuzai told Yin Zizi that their company's technology and information might have been copied by hackers, and Xian Yuzai never paid attention to Yin Zizi's plan to arrest the Bitcoin withdrawal person. Instead, he kept asking Yin Zizi about training.Are the liquid rumors true?

Xian Yuzai negotiated terms with Yin Zi Zi. He asked Yin Zi Zi to donate money to people in the primary industry, and then presented evidence to the public to prove that the culture medium was safe. However, Yin Zi Zi only accepted the donation because the culture medium was top secret..Hong Xinye actually fell into the water because he lost control of the car while speeding. Now he is unconscious. Yin Ziyi is wondering why it happened today?So I started to question whether the threat came from someone inside the office?Judging from the scenes that he has been secretly recording today, Yu Caiyun deduced that the hacker organization that attacked BF should not come from abroad, because the terms and punctuation marks are only Koreans, so someone pretended to be an X citizen to hide their identity..Yu Caiyun thought that maybe the talents around Yin Zizi needed to be disguised like this, so Yin Ziyi began to doubt every core employee around him.
