Bofuri (The Strongest Shield Of Tensura) - Chapter 48 - Forty Eight

Su Yang was an average university student in Shanghai when he received a system that allowed him to add points to things. The point system provided him with missions and by clearing them, he would gain points.

Fu Hongxue was a cripple, born with a lame leg and subject to epileptic seizures. He was also one of the most powerful, legendary figures of the martial arts world, with a dull black saber that was second to none. His fame made him a frequent target of challengers, but whenever his saber left its sheath, only corpses would remain in its wake. One day, however, Fu Hongxue rescued someone whom he should have killed…and in doing so, set of a chain of events and a conspiracy that would rock the world.

Finding himself in an Last Airbender without an airbender around, a transmigrator waterbender goes on an adventure to stop the worst from happening to him.
