That Gu Worm.
It was obtained by Qin Feng when he initially treated Luo Hongyan's throat.
According to the Ghost Lady, it took her a full eight years to find it on Snow Lotus Mountain and she also fed it numerous Heavenly Materials and Earthly Treasures.
He was fully aware of how formidable this Gu Worm was, which is why he chose to nurture it.
He had heard Hong talk about how, during the previous Sky Dragon Martial Arts Tournament, the Ghost Lady used this very Gu Worm to kill a top ten expert on the Sky Dragon List. The Ghost Lady herself did not have a high level of cultivation, yet she was able to use the Gu Worm to kill him, which speaks volumes about the power of this Gu Worm!
Moreover,
after obtaining it, Qin Feng also continuously nourished it with the Heaven and Earth Essence Qi from the Ten-thousand-year-old cliff cypress.
Then he used the Evil Qi Night Pearl, obtained in Jiang City, allowing it to absorb the Evil Qi from within, and also fed it with Immortal Energy.
