Using the pilot, I opened the wooden box on the first floor and took out cigarettes. Since the front was relatively simple, there was no damage + blood all over the floor, so I used cigarettes to sell blood like crazy.

As a result, he stood up and output all the time, and the boss was almost killed before he could even hit the first round of attacks.
