"Biochemical Longevity" by Jordan Chan Invincible and Zang B are young people who love to talk nonsense all day long and only go to the commercial building to look after the VCD stall at three or four o'clock every day. One day, the two of them went to pick up the car on the order of their boss. Unexpectedly, they bumped into a gangster carrying a biological and chemical weapon. Unknowingly, the two people returned to the commercial building with the infected drink and the gangsters. Little did they know that their biochemical weapons could turn ordinary people into zombies that are not afraid of guns and knives and bite everyone they see. As a result, everyone in the building, from the guards, the sushi chefs to the cleaning staff, turned into zombies. Only the mobile phone seller Bakugoma and his wife, the beauty girl Homaki, Jelly and this pair of living treasures were left. How should this group of people break out of the siege and return to the Yang Realm? Two idle young and Dangerous guys who specialize in selling pirated CDs only go to the commercial building to look after the VCD stall at three or four o'clock every day. One day, the two of them went to pick up the car under the order of their boss. They pranked a stranger in a suit and forced him to drink a can of magical "potion". It turned out that the potion was the latest biochemical weapon and was about to be sent to the hands of international criminal groups. The "Shou Zhi" who mistakenly drank the "biochemical" drug followed Young and Dangerous back to the mall. The invincible weapon had not exerted its power to exterminate mankind, so the Shou Zhi launched a revenge plan on his own. When the corpse bites a person, the person will deform, causing a chain reaction. The gate of the shopping mall is locked, and a group of actors, including guards, sushi chefs and cleaners, are trapped inside, creating a "siege" situation and kicking off a melee of "human corpses". Later, a group of six people tried to escape by taking the elevator, but Wu Di discovered that Jelly was missing. At this time, Jelly rushed into the elevator, but the elevator was overloaded. Bao Yaju pushed Jelly out and the elevator was shut down. At a certain floor, they got out of the elevator and everyone (including Ju's wife) beat him and left him in the elevator. The Zombie Busters team walked down the stairs and found Jelly being eaten by zombies. Invincible picked up the electric drill and smashed the zombie's head. In the end, Invincible decided: take the guy. Later, Zombie B was infected by zombies while trying to save Ju's sister-in-law, and Wudi Xijuan dragged him away. In the guard room, Mourning B asked Invincible to take a photo for him and then kill him who was about to mutate. Invincible has been reluctant to take action. At this time, the infected guard "Big Man" caught mourning B and tortured him who was dying. Invincible was very angry and hacked the zombie guard to death with Zombie B's knife. In the end, Wudi stabbed Mourning B... The only two people left planned to leave the parking lot. They broke through the siege and were assisted by the zombie-level "Little Sushi". In the meantime, Wu Di had a hallucination: Mourning B was helping him. First ending: They arrived at a gas station. Wuwei planned to call the police, but found that the phone was invalid. At the same time, he saw a TV show and learned that most drinks were injected with bacterial liquid. He looked back at the car - Homaki was drinking the bottle of Grapevine - the bacterial liquid that turned the gang boss' son into a zombie. Wuwei returned to the car and drank the remaining sip of "Grape Shit"... PS, if you watch the entire movie patiently, you will see the second ending of the movie: they arrived at a gas station , Wuwei planned to call the police, but found that the phone was invalid. At the same time, he saw a TV show and learned that most drinks were injected with bacterial liquid. He looked back at the car - Homaki was drinking the bottle of Grapevine - the bacterial liquid that turned the gang boss' son into a zombie. Wuwei looked at the car again and found that Xijuan was not in the car. He walked back to the car and Xijuan suddenly appeared and bit Wuwei from the side...
