Gu Miraculous Doctor

The courier boy Zhang Tianci was originally an ordinary young man struggling to make ends meet. When he traveled deep into the mountains with his parents, he was accidentally parasitized by an ancient relic. This mysterious Gu can not only eat strange diseases and help people live longer, but also absorb life energy and feed back the host's cultivation - it is both a heaven-defying golden finger and a life-saving charm. When he became famous with his "Poison-Eating Divine Gu" that cured terminal illnesses that rich people and famous doctors were unable to do anything about, he was immediately recruited by a cultivating family and a reclusive sect, and was forced to embark on the road of escape and cultivation. On the way, he met Lin Shiyin, a college classmate, and the two traveled around the world hand in hand, practicing medicine to help the world while fighting against all forces that coveted his power. From an urban ant to the supreme being in the immortal world, he used poison as the way and used gu to prove the way, and finally became the only "gu-eating immortal" in the ages, shaking the three realms of gu!
