Raising Gu: I Have a System Gu

Yan Xiu traveled to a world belonging to Gu masters. In this world, Gu was respected and Gu could be refined from various materials and spiritual insects. However, the success rate of refining Gu in this world is extremely low, and powerful Gu requires thousands of times to be successful. Fortunately, the little cheat he secretly developed while playing the Legend of Love Immortal in his previous life came to this world with him! The unlimited deduction ability is unlocked at the beginning. As long as the basic theory and direction are given, powerful Gu insects can be deduced with a success rate of nearly 99%. While others were still shouting "It hurts! It hurts too much" because of the failure in refining the Gu, Yan Xiu already had countless top-quality Gu insects! The larvae of a few millimeters can prey on frogs, such as the rhubarb beetle + longhorn beetle = sea worm. Bookworm + Perfection = Double Eye Gu. There are also Blood Gu, Yan Quan Gu, Nail Bone Gu, Xuanji Gu, Three Corpses Gu, Beloved Gu... This novel and its characters are purely fictitious.
