"In this world, definitely no more than two people could concoct the Nine Deaths Demon God Extermination poison. Even Master has no confidence in concocting the ten deadly poisons from the Poison Scripture. Could it be that the Yin Medical Sect has reappeared? Master once said that if the Yin Medical Sect emerged, it would certainly wreak havoc, poisoning the innocent. The poison that Song Qingyu encountered last time, and the one this time, are probably both from the Yin Medical Sect. No one else in this world would concoct such poisons except for the Yin Medical Sect."
Tangyu pondered in his heart about the Yin Medical Sect, something he had heard about from his master since he was young. His master always taught him to eradicate the Yin Medical Sect wherever found, to prevent them from bringing disaster upon the world.
