- Description from novelbuddy

A man who had emerged from the world’s most secure prison—God of Death Island, known as a super-powered being called the God of Death, had grown tired of the bloody storms abroad and now, like a hidden dragon, he had returned! But due to an accident, he became the contract husband of a beautiful CEO! From then on, he ruled the city, crushed the petty and wicked, and embarked on the tyrannical journey of an urban legend!

The dawn era after the end of the half century has gradually rebuilt the order, abandoned civilization, and is full of undivided violence and desire.
The noble and powerful pioneers are in charge of the city, and the evil and mad plagues are in the wilderness.
Pure human beings who cannot mutate are the weakest, dominated by the rulers of the pioneers, and are not as good as animals in the wilderness.
A purely humanized young man with a worldly experience has quietly entered the WTO, holding a three-foot long knife and a long-distance desire to boil in the world of purgatory. From the nameless name to the sorrow of the Supreme Court, the name of the black ride is resounding!
