Reborn as Yamcha

After a car accident, ordinary college student Li Xing transmigrates into the world of Dragon Ball and discovers that he has become Yamcha during the Saiyan invasion, facing imminent death. At the brink of death, the Martial Arts Breakthrough System activates, giving Li Xing the chance to grow stronger through battle. He saves the original Yamcha, who is about to be killed by a Saibaman's self-destruction, then resolves to use the System to rapidly increase his strength and change his fate. (P.S. This was originally written in the first person, but has now been changed to the third person at readers' request. Some chapters may not have been fully revised, so please point out any oversights.)
