Li Zhien was originally a low-level immortal cultivator in the Tianji Sect of the Huaxia Kingdom. He only had talent but no financial strength to become a disciple. Until one day when his senior brother asked him to go to Sakura Country to help retrieve the secret treasure, he directly traveled to a different world with all the heroes of Sakura Country. Li Zhien Human Race Ability: Cannot defeat monsters and upgrade. Just when he lamented the unfairness of the world, he discovered that the herb picked by the most common E-level people turned out to be Breitling Herb! From then on, Li Zhien embarked on the path of collecting medicinal herbs and practicing medicine. Joke! I, a Chinese cultivator, need to kill monsters to level up?
