A 29 year old civil employment exam student wakes up in a blank white room and meets a baby angel. This baby angel informs him that he died in his sleep due to heart disease like his father and grandfather. Remembering his mom and their last conversation he says that he will take on a series of life and death tests that the baby angel offers him. From this point on he must put his life on the line and fight in the stage called ‘Arena’. And Every time he clears a test he will gain abilities and weapons to increase his strength. All to clear the tests and get his life back. This is his story of his fights in the ‘Arena’.

Some people transmigrate into Emperors, others become wangye.

They live in luxury; their hands covering the Heavens.

Some people transmigrate into shizuns, or sect leaders.

They would have the respect of all, their powers supernatural.

Some unlucky souls become villains, but even with their terrible reputations they would still have enough power to summon rain from the sky, maybe even manage to kill off the protagonist.

But Li Changtian, a stand up young man from a good family, who died on the battlefield protecting someone, widened his eyes.

He! Transmigrated!

Into a person everyone wanted dead, with an unabsolvable crime!

Li Changtian: “??? Wait wait, did something go wrong somewhere?”

The magistrate of the Imperial Justice Bureau, Yan Shu, who hated injustice more than anything in the world had just stepped onto his head and said in an ice cold voice: “A life for a life.”

Li Changtian: “&%%%￥&￥#@”
