On the fourth day of the crisis, Jack learned from Alex that the password for the server connecting Taurus City to the outside world had been resolved, and he could now communicate with the outside world. He also learned that the government had announced that a serious influenza virus had broken out in Taurus City, and that in order to avoid a global disaster, the only option was to impose a comprehensive blockade on Taurus City. Jack believes that all the facts should be sent to major foreign media now, so as to force the government to send aid troops to rescue the survivors of Golden Bull City. At the same time, Alex also discovered a "control" plan in Lucy's information, but the specific situation took time to decrypt. At the same time, he also recovered Lucy's mobile phone records during the period of disappearance, and learned that Lucy had never left Taurus City. She had been in a suburban park on the outskirts of Taurus City. Jack set off to the suburban park to look for Lucy, but when Jack arrived at the suburban park, he received a call from Alex and learned the shocking truth that Lucy might be dead, and that the so-called "Control" plan was the real cause of the zombie crisis in Taurus City. Lucy also joined this plan without knowing the truth. Lucy didn't want to join in with others and was ready to tell all the truth, but unfortunately she was discovered by other researchers. Lucy's current location is the research institute where this plan is being carried out. In anger, Jack decided to destroy the research institute that had killed millions of lives. However, when he arrived at the location of the research institute, he found that there was no way to enter the research institute. Jack suddenly remembered that the military area where he was a soldier was not far from the research institute, and he would definitely be able to find C4 explosives there that could blow out the entrance to the research room. Jack immediately set off for it. 
But when Jack arrived at the military area, he found corpses everywhere, as well as several mysterious and powerful monsters. Jack remembered that those might be the purpose of the research institute - modified people who have no idea and can only execute orders! With his superb skills, Jack eliminated these modified people and came to the military weapons depot. He saw the military commander who was still breathing. The commander handed Jack the door card of the weapons depot and then died. Jack found the C4 explosive in the weapons depot and returned to the research institute. 
Jack successfully blew out the entrance with the powerful C4 explosive and entered the inside of the institute. After eliminating all the modified humans on the first underground floor, Jack came to the research room on the second underground floor and suddenly found his wife Lucy in a nutrient dish. Jack wanted to release Lucy, but his reason told Jack that Lucy would die soon if he did so. 
At this time, the voice sounded, and it turned out to be Dr. Neo, the person in charge of the entire project. Dr. Neo said frantically that he had "executed" Lucy himself, and then released the cyborgs to attack Lucy's nutrition dish. Jack, in a rage, eliminated the cyborgs that appeared. Before Lucy died, she asked Jack to leave Taurus City and not to avenge her. Jack came to the core research room at the bottom of the institute and met the crazy Dr. Neo. Dr. Neo also ordered his men to release the modified people to capture Jack, let Jack accept his research and then left. But unexpectedly, the Cyborg suddenly lost control and killed Dr. Neo's men. After destroying the Cyborg, Jack began to hunt down Dr. Neo. 
Dr. Neo came to the ground, but was suddenly shot by a mysterious man. In a frenzy, Dr. Neo injected himself with the latest transformation fluid, and even he became a transformation person. Jack fought it hard and finally eliminated Dr. Neo. Jack returned to the institute, retrieved Lucy's body, and left this sad place. 
But everything is not over yet. . . . . .
