I'm Opening a Restaurant in Collapse

[All kinds of martial arts, this is cooking]
[Murder weapons can't be used to cut vegetables?Is cooking such an inconvenience? 】
[The reason why I am the No. [-] chef in the collapsed world is not because of the best cooking skills, but because I am good at cooking, and I can cook if I can. 】
All in all, this is the story of an invincible chef opening a restaurant in the world of Honkai, while fighting the blood (?) story of Honkai.
