1. When I came to the gun room, my little daughter followed me. I pushed open the wooden frame and found a crack in the wall, suggesting that "there is cold air blowing in the crack, and it should be broken if you hit it hard."

2. Blast this gap with a tubular Grenade to let in cold air. Several tubular grenades can be found on the nearby table, so it is not enough. There is also a lock opener on the table. Then you can see the little girl in the cold wind, crazy output to kill the little girl.
