Dudian was scared. He pushed against the door. The door was old and rusty. After the first punch from the undead cracks formed on the door. Fortunately there was a sofa barricading behind the door, because otherwise by then it would have been broken through already.
Mason and the other two were frightened and hurried to the sofa to reinforce it by pushing. The wooden frame inside the sofa had long been rotten, so after the forceful push by the four of them it cracked right in the middle.
Bang! The door was broken through and limp palms stretched inside casually clutching. Fortunately the undeads' bodies belong to adults so they were much taller than Dudian. They couldn't catch him on the first try.
Dudian had forgotten that most of these materials were useless after 300 years of corrosion. He shouted at the others, "Quickly, jump from the window down to 11th floor!"
