"Yes, Shu."
Lu Xi'an organized his thoughts and said, "It was like that here back then, large-scale use of high concentration X-17 Strain, aimed at Type D-1 Neo-Humans.
"Then people basically died from skin ulcers and suffering.
"But Shu survived, and the observer who used this laptop back then also survived.
"The observer said he managed to survive for such a long time because of the observation site. Could the top of East Mountain where Shu stayed then also be related to the observation site?"
Yao Wei said, "Was it the green water in the pit related to the observation site?"
"You're right."
Lu Xi'an nodded slightly and said, "But we just don't know what this observation site is... According to the observer's log, the observation site is supposed to be confidential, he did not reveal it in the log.
"What kind of secret could it be... the X-17 Strain is mentioned in the log, but the specific observation site is not discussed.
