Qin Jin, a master of ALS whose chef license has been revoked, alarmed the National Health Commission with his seven-day immortal soup. This soup can kill someone for seven days, but it requires seven kinds of poison.

And the "Seven Days Notes" written by young A Ye is quietly revealing the bloodiest truth behind the scenes - this soup should not exist in the world.
