Contracted Phantom Beast

In a world filled with contract rules, the phantom beast master uses the contract as a guide to conclude an eternal oath with the phantom beast. A young man who came out of the slums with an extraordinary life experience, and with the oath he made when he first contracted with the ancient fantasy beasts, contracted with all the beasts in this world belonging to the fantasy beast master, achieved his goal, and became the myth of an era! The story is richer than the introduction. Writing the introduction is really a painful task. If it weren't for the suggestion from my book friend, I wouldn't even bother to do it (´Д`) A new group has been created where everyone can exchange opinions and suggestions.
