Douluo: You Can Become Stronger by Treating Diseases

Pingchen traveled through the Douluo Continent, only to find that his soul had transformed into a sixty-seven-year-old old soul master whose soul power had stopped at level 15 for the rest of his life. After wandering for half a lifetime, the leaves fall and return to their roots. However, Pingchen unexpectedly inherited the old soul master's last obsession and treasured knowledge of herbal medicine. I originally wanted to hang a pot to save the world and end my remaining life, but I unexpectedly discovered: Healing others can actually feed back vitality and enhance soul power! Since then, Douluo Continent has had a white-haired doctor walking in the countryside. He does not hunt soul beasts or take soul rings, but only uses silver needle herbs to heal the suffering in the world. Cure stubborn diseases, detoxify strange poisons, save soul masters, heal mortals... Others rely on hunting to become stronger, but I rely on healing and saving people to level up! This is a Douluo path that belongs to doctors!
