In this world, all citizens who reached 18 years old could acquire a chance to temporarily reincarnate to another world.
They could reincarnate to various worlds such as an Eastern fantasy world, Xianxia world, Western fantasy world, an urban world with advanced martial arts, or even a sci-fi world of the future.
They would acquire a mission along with the ability required to survive in that particular world.

I Have Awakened The Deduction System

The battle in the old temple was still in full swing.

As the beasts roared, Shangguan Fei's face grew uglier and uglier.

He had never thought that these seemingly unintelligent magical beasts would become more and more courageous the more they fought and were so difficult to deal with.

Even the sharp sword in Shangguan Fei's hand and the claws of the five-clawed Golden Dragon were extremely sharp. Not only could they cut through iron as if it were mud, but they could also destroy mountain rocks.

But now, he could only leave wounds on the demonic beasts' bodies. He couldn't even hurt the demonic beasts' core, let alone kill them.

Except for the few demonic beasts that had been seriously injured by Shangguan Fei's sharp sword at the beginning, the other demonic beasts were still able to move despite being badly injured. They were still very aggressive and dangerous.
