Rebirth: Start by Collecting Debts of Gratitude

The most difficult debt to repay in the world is often the debt of favor! After resurrecting his life, Fang Yunze suddenly saw a mysterious bond book in his field of vision. Each bond represented a favor owed to Fang Yunze by someone, and it would take effect as long as it was torn off. In reality, every time someone owes Fang Yunze a favor, this bond book will be replenished. In an instant, snobbish relatives, female classmates who had once dismissed Fang Yunze, and teachers who asserted that Fang Yunze would have no future all began to come to his door in a low tone. Because they knew that Fang Yunze had a lot of connections, and if they wanted to get Fang Yunze's help, all they had to do was promise to owe him a favor. Just when Fang Yunze was using various human relationships to make a prosperous life, his relatively stable life was finally broken by a special human bond...
