Leng Luo didn't know that ever since Gu Yuying was little, he had a kind of immunity, or rather, the whole Gu Family had a kind of immunity that his eldest uncle had developed.

Moreover, all four brothers were trained like soldiers since they were young, so they are physically robust. For them, drugs of this potency would only have a temporary effect.
Nevertheless, this is something he would not tell Leng Luo.
