I'm Already the Supreme Archmage, So Why Cultivate Immortality?

[Invincible Protagonist] [System Destroyer] [Magic System Clashes with Cultivation System] [Pure Wish Fulfillment]

Liang An had transmigrated to a cultivation world and had just reached the Golden Core stage when he was struck by lightning. Then he transmigrated again, this time to a different world governed by magic. After cultivating all the way to Supreme Archmage, Liang An began to suspect there had been something fishy about that lightning strike. To remove the dormant [Cultivation System] inside him, Liang An tore through the planes and returned to the cultivation world. He destroyed his Golden Core and forcibly extracted the shady [Cultivation System] from his body! Though all his cultivation was gone, Liang An had a magic ring in hand and thought, I'm already a Supreme Archmage. There's no need for me to keep cultivating, right?

Pure wish fulfillment. If it's not satisfying, come after me!
