Rebirth: Reversing the Tide

The protagonist is reborn at age 22, just after college graduation and on the eve of starting a business. He has 10 years before his family is ruined and he dies tragically in his previous life. His enemies have not yet fully risen, and the core regrets have not occurred, giving him ample time to turn the tables. No system, no cheats—only the memories of his past 10 years to exact revenge step by step.
