Programmer Su Lin died suddenly.
When he woke, he found himself transported to a world of cultivation that had been invaded by a game System. Monsters dropped gear, killing people yielded spirit stones, and the natives had only one life, while players could respawn three times.
Even better, he could see the underlying code of the world.
Someone killed him? He found a bug spot, farmed monsters there, and reached the seventh level of Qi Refining in three days.
Surrounded by enemies? He lured monsters in to wipe out his foes, then picked up gear until his hands were full.
Later, I exploited a bug and cultivated my way to immortality.
