A Thug Transmigrates into the Cultivation World, and His Aloof Master Pursues Him Instead

Master, please let me go!!

Yun Shi, a Foundation Establishment-level punk, has barely transmigrated into the cultivation world when he receives a hellish mission:

Assassinate Gu Xuanling, an immortal lord on the brink of ascension.

He can't make a dent in the target, but he can't escape the immortal sword's reach, either.

The System dangles rewards to hurry him along, but Yun Shi just wants to lie flat, loot his master's estate, and wait for a chance to stab him in the back.

But he never imagined that this cold, aloof immortal lord on the brink of ascension would turn into a little white snake and demand cuddles every single day!

He even gets mad if Yun Shi won't kiss him?
