Starting Out: The System Locked Me Up As a Lunatic

[Invincible + Sword God + System Abuse + Fast-Paced] Lu Chuan was supposed to transmigrate to a high-martial world, but due to a screw-up by a dumb system, he ended up in a cultivation realm instead. To prevent its host from getting killed, the dumb system forcefully locked Lu Chuan away for 100,000 years. Unable to adapt to the cultivation realm’s template, the system could only have Lu Chuan practice sword techniques from the high-martial world. 100,000 years—an entire hundred thousand years—later, Lu Chuan had become the ultimate Sword God... …and also a complete lunatic.
