Rebirth of Japan's Strongest Contractor

The top master from Tianyu accidentally traveled to Gu Tianming, a student studying in Japan with the same name and the same surname. A series of jumping cases broke his peaceful life, letting him know that the world is not ordinary. Under the calm water, some people activate their blood vessels to gain superpowers, some people train their bodies day after day to become holy, and some people hold the system to protect world peace. And he has neither noble blood nor powerful abilities, nor does he have a heaven-defying system. But what he doesn't know is that the so-called system is just a simplified version of the Tianyu game system. Gu Tianming is more familiar with its existence than anyone else. How to survive in this dangerous world with only his super thinking will be the huge challenge he will face next.
