Heavenly Remnant Star Prison

After surviving the tribulation and becoming an immortal on the Mocheng Continent, I broke through the barriers of time and space and entered the legendary Immortal Realm. But it was nothing like I had imagined. A vast prison held every immortal captive! Poisonous gas in the air corroded their immortal bodies, while invisible chains tightly sealed away their powers. Everyone struggled to survive there. Was this the Immortal Realm, or was it hell?
