Alchemy of the Headless Horseman

[Alchemy, easy direction, time travel] Galilei has always believed that Los Angeles is the city with the best security in Nural. It wasn't until he experienced kidnapping and sacrifice, murderers chasing him across the street, and extortion and robbery that he changed his mind and decided to dedicate himself to the security of Los Angeles. He would kill all the bad guys, dig deep into the murderers, and dig up the ancestral graves of the gangsters. A sacrifice completely changed Galilei's life. After his head was blown off, he embarked on the path of an alchemist for revenge. Talking crows, regenerated cyborgs, floating alchemy cities, a dream world that connects everyone, extraterrestrial visitors on the back of the moon, a 'zoo' hanging forever in the sky, a world trial once every thousand years, after seeing all of this, Galilei just wanted to say one thing. "This world is hopeless."
