Maya, wearied and resigned, said, "I really can't accept this."
Lin Wu replied, "With so few people, we can't loot the airdrop. Even if the walls stood, our bullets wouldn't last an hour."
Maya looked at Lin Wu who was puzzled, then turned back to Maya, who said, "Your words just reminded me."
Having said that, Maya shouted, "Hello, everyone, I'm Maya, and we still have a chance to win."
Lin Wu glanced at Maya skeptically, "Really?"
Maya: "Yes."
Lin Wu looked at Maya.
Maya added the second half of her statement: "Let's try it."

Maya's tactic was to give up on the airdrop and put all 130 people into the laboratory.
First step: Dig a pit, throw the chief engineer into it, and cover it with an iron plate.
Second step: Still digging pits, create an earthen rampart position.
Third step: Assign tiers, with the first tier directly facing the zombies, the second tier arranged layer by layer around the center of the earthen rampart, followed by the third and fourth tiers.
