Back then, Yan Fei was able to eliminate the Ancestral Land, largely because it was infected with this special virus and lost its sanity. So after obtaining this special virus, Yan Fei did not destroy it, but instead brought it back to Dream Island and asked Yang Qi to conduct further research on this special virus.
After the appearance of the Ape Tribe reconnaissance ship, Yan Fei sensed danger and asked Yang Qi to accelerate the research progress on this special virus. With an Ape Tribe warrior as experimental material, Yang Qi's research on the special virus reached a new level. He has conducted deep processing based on the previous virus and greatly enhanced the infectiousness and lethality of this special virus.
