Signing a Contract with the Heavenly Dao Made Me the System's Chief Tester

Su Bai signs a contract with the Heavenly Dao and becomes the one and only System tester.

He travels through countless worlds, testing Systems for the chosen ones of destiny to make sure they meet the standards.

And so...

In a world of martial arts, while testing the Reading System, he exploits a bug. By endlessly poring over martial arts manuals, he enters the Dao through martial arts and becomes the supreme master of the martial world, single-handedly defeating the strongest fighters of several nations.

After the test, the Heavenly Dao seals the System away and turns around to give the original chosen one a Wage Slave System.

In a world of ghosts, the Fooling System he tests also develops a bug. He starts toying with people, ghosts, and even the Heavenly Dao itself, spreading darkness and plunging the entire world into terror.

After the test, the Heavenly Dao is exasperated and seals that System away once again.

In the matriarchal world, he tests the Virtuous Man System. This time, he simply becomes the king of the women's kingdom.

Test complete...

Heavenly Dao: "Su Bai, System tester, you're deliberately here to cause trouble, aren't you?"
