"So it's a record like this, this person is quite talented indeed," Li Fei exclaimed after reading the content of the small booklet he found on Ghost Wolf.
This booklet didn't record any secret martial arts manuals, but it wasn't like last time—a useless novel.
It contained Ghost Wolf's personal notes on poison research.
The crossbow arrows used by the "wolf pack" were all smeared with a highly toxic substance, and this rapidly effective poison against martial artists was concocted by Ghost Wolf himself.
He initially bought poisons from the black market but found them ineffective, so he started researching bit by bit. After many years of effort, he finally developed this potent poison, which became the "wolf pack's" secret weapon.
The booklet in Li Fei's hands recorded the experiences and development process of Ghost Wolf's years of poison concoction.
As for the liquid in that iron pot, it was the poison made by Ghost Wolf, which he called "Nether Spring."
