Arc 1Rescue Through the Tunnels
Shen Jin expanded his underground base, learned about the evolving Zombies and the Gene Lock, and rescued Yang Ao before heading back to Wanyu Company. He saved Shang Qian and Sun Can from Lu Qiang and the Zombies, then brought them through the tunnel toward his home, where Li Moxiao confronted him about secretly eating steak.
- Shen Jin used his hidden base to trap Zombies, gather supplies, and learn from government broadcasts about mutations and the dangers of the Gene Lock.
- Shen Jin freed Yang Ao from the pit after Yang Ao offered information about two vials of Gene Optimization Serum, and agreed to let him join the Gathering Place.
- Shen Jin returned to Wanyu Company and intervened when Lu Qiang attacked Shang Qian, but Lu Qiang awakened his combat instincts and seized Shen Jin.
- Sun Can fought Lu Qiang after taking a Zombie Crystal Core, defeated him, and collapsed as the other survivors gathered to face the Zombies climbing the stairs.
- Shen Jin sealed the stairway and windows, then agreed to take Shang Qian with him after a series of misunderstandings about his relationship with Sun Can.
- Shen Jin led Shang Qian and the unconscious Sun Can into the tunnel on folding electric bikes, then returned to seal the entrance and left Shang Qian waiting.
- Shen Jin tried to feed his guests a modest meal, but Li Moxiao woke and accused him of hiding steak, so he gave her steaks and cornbread before Shang Qian arrived.
