There's a saying that goes, "Men and women working together makes for lighter work." Although Tang Manhong was still the same, always wearing a stern face for Tang Ye to see, she had started to soften up from time to time, which made their cooperation in handling the virus infection incredibly efficient.
Tang Manhong told Tang Ye that the infection was caused by a corpse poison Gu. Tang Ye's earlier guess was not wrong, the symptoms of the infected virus were similar to those of the rotting corpse poison, in that both corrode the flesh. However, Tang Ye was mistaken about one thing, he thought that this corpse poison Gu was an upgraded version of the rotting corpse poison, but it was actually the other way around, the corpse poison Gu was in fact the primary version of it.
