I don't know what the purpose of the person sending me the package is, but I don't think the sender would be Wu Yan.

However, I cannot deny that these things

have made me quite curious. I didn't want to get involved, but my strong curiosity made me restless.

So after listening to the recording, I searched through numerous materials about Erlang Shen and consulted professors in the history department. The answers I got were varied.

After much contemplation, I decided to go to the Archaeological Research Institute and ask Tao Xiuhong and Qiu Shan, who were with Wu Yan during the excavation of the Dujiangyan Irrigation System, about the situation.

But to my surprise, these two individuals could recall the events of that evening vividly, yet what they described was completely different from Wu Yan's records.

Qiu Shan was the second person to descend into the tomb, approximately twenty minutes after Wu Yan.

To say "tomb" isn't entirely accurate because after descending with a rope ladder to the bottom of that crevice, she confirmed that there was no burial chamber, only a pile of larger stones.

If there was anything special about the place, it was that the interior of the mountain seemed to have been hollowed out, forming a cave that resembled a sealed bottle.

At that time, Qiu Shan was amazed by this natural wonder, to the point that she didn't notice Wu Yan's unusual behavior right away.

It wasn't until Tao Xiuhong also landed that they noticed Wu Yan, who was trembling with excitement, muttering something.

"It sounded like sentences from legends, fairy tales, or the Shan Hai Jing," Tao Xiuhong said.

According to their accounts, it seemed that Wu Yan had fallen into a state of nightmare. They had heard from the locals that you should never wake someone from a nightmare. Therefore, they placed Wu Yan on a flat rock and proceeded with their sampling and exploration.

About an hour later, Wu Yan woke up, but at that time, his expression was frantic, and he completely disregarded Qiu Shan and Tao Xiuhong. He hastily climbed out of the bottom of the cave and immediately drove back to Chengdu.

Afterward, Wu Yan's whereabouts became mysterious. The two members of the same team only saw him four times within two months, and each time he was disheveled and in a hurry.

Not long after the beginning of 2023, Wu Yan was put on unpaid leave by his organization, and the few of them never met again.

I expressed my gratitude to them and requested a survey report compiled by Qiu Shan. Since it wasn't a highly classified document, she casually gave it to me.

I compared the photos taken by Qiu Shan with the ones I received in the package and confirmed that they were taken in the same location.

As for the "corpse with three eyes on its face" mentioned by Wu Yan, after conducting various investigations, I can basically confirm that it was an illusion caused by his mental issues.
