My Cultivation Skills Can Be Upgraded Infinitely

On the border of the Southern Territory, demonic flames surged into the sky; within the sect, a mountain rain was about to come. Chen Mo, an outer disciple of the Iron Sword Sect, was guarding a small medicine garden. With mediocre qualifications, he was stuck on the third floor of Qi Refining with no way forward. No one knows that this unknown medicine garden guard has long been replaced by a different person, and he also has a proficiency system that can upgrade the skills and spells. It starts from the transformation of the first-level Spiritual Rain Technique into the Foundation-Building Spirit Control Technique, and from the refinement of the first batch of Qi Gathering Pills. Refining medicine, making talismans, martial arts, swordsmanship... Everything that passes through his hands can be infinitely advanced. Troubled times are coming, and corpses are everywhere. Chen Mo wants to carve out a path to immortality by working hard day after day in this world of immortality, where the jungle is strong.
