(Marvel + Prison + Traveling Through the Heavens + Imprisoning the Gods of the Heavens + Multiple Female Leads)
As the name of the god-level prison implies, all gods must be imprisoned when they come.
Joker: I am the king of Gotham City, and Batman is being fooled by me, hahahahaha.
Qian Ye: Really? I'll send you to my prison for rehabilitation.
Loki: I am the future king of Asgard, you ants, kneel down before me.
Qian Ye: You have committed the most serious crime of pretending to be fake in the universe. Please go to prison for reform.
Thanos: So what if I wipe out half the population of the universe for my ideals.
Qian Ye: Your thoughts are very dangerous. Send me to prison for reform.
Space-Time Administration: For the sake of peace in the universe, I will arrest anyone who violates time.
Qian Ye: Time Management Bureau? Whoever gave you the right to speak with the power of this universe will send you all to prison for reform.
Qian Ye: Ask me if I have no strength? What a joke, watch me travel through the heavens and seize treasures to cultivate my god-level prison.
It's pretty, but it smells a bit rotten.
