I Rely on Slaying Demons to Achieve Immortality

You can spend your life energy to infuse martial arts, you can perform unlimited deductions, and kill monsters to get the opponent's life energy. Ye Feng's mortal body entered the game, starting as a county police officer, measuring life and death with a blade, and causing the liver and gallbladders of monsters who had lived for thousands of years to rip apart! From [Fuhu Fist] to [Soul Chasing Step], from [Demon Slaying Sword] to [Breaking Mountains and Rivers with One Strike]! He sheathed the sword and raised his eyes to look at the vast world. I heard that there is a thousand-year-old demon in the ancient temple deep in the mountains, and there are saints in the fairy court above the clouds, each of whom has experienced endless years. I came here with my sword in hand just to borrow from them for thousands of years to prove my path to immortality.
