After giving the order, Gao Yang organized rotational guarding, and everyone equipped themselves with simple gas masks hung around their waists.
Although they had encountered a chemical weapon attack once, the simple gas masks were not designed for chemical warfare. Since chemical weapons could be fatal through skin contact, and without protective suits or air tanks, the simple gas masks were quite useless against chemical weapons. Therefore, the gas masks were prepared for that particular thing.
What was that thing?
That thing was the Skunk Bomb.
They should have assigned a code name to the Skunk Bomb so that they could simply shout it out when needed to know what to use, but Gao Yang and his team were too lazy to come up with a new code name, and they simply referred to the Skunk Bomb as "that thing."
