My Gu Can Cultivate on Their Own

When Fang Yuan was transmigrated into a world where Gu Breeder was the main profession, he found that he was not gifted.
Not only that, the Gu in his body could cultivate on their own.
[Your Iron Skin Gu has trained profoundly and has achieved the Gold-grade!]
[Your Bloodthirsty Gu has begun to multiply itself into a swarm of Bloodthirsty Gus!]
[Your Sunlight Gu has been absorbing the power of the sun for years and has gathered the Truth Flame of the Sun!]
[Your Drunken Gu has evolved into a Soul-reaping Gu. Your control over it has risen by 100 folds!]
[Your Flying Sword Gu was hurt in battle. Amid its desperation, it has evolved into a Sword God Gu!]
“Heck, even Gu undergoes involution as well now?” Fang Yuan let out a sigh.
