Insect Witness

The small bookcase on the left was filled with books. Some of the books were stacked on the floor, stacked and angled like thick books. Diagonally across from the bed was a large writing desk, nearly three meters long and more than a meter wide. In one corner of the desk was a computer with a wide-band net, in the other a lamp, and several workbooks.

On the right was a wardrobe and a dressing table filled with girls' belongings.

Opposite the bed was a window. Pushing open the window, a gust of fresh, moist air blew against his face. Outside the window was a clear brook that ran to the bottom. Next to the brook was a row of willow trees. After going through a few frost attacks, they became a faint golden color.

Shen Yuan's gaze slowly caressed everything in the room, as if Su Heshan's smiling face had left a mark in every corner of the room.

On the desk, in an open album, were photographs taken from who knows where. There were mountains towering into the sky, raging rivers, towering old trees, and dark, mossy holes. Almost all of the photos were from the scenery of nature. Unexpectedly, among all the photos, there was not a single one of Su Heshan!

In his three years of being in a relationship with Su Heshan, he had never found Su Heshan to have such a hobby! Every time he went out with Su Heshan, as long as the time he spent outside exceeded his plans, he would find an excuse and hurriedly return to the laboratory. In his eyes, a mountain was a mountain, a tree was a tree. It was just a normal phenomenon in nature. Because of this, he neglected the elements of Su Heshan's life.

Shen Yuan opened a blue bound notebook next to the photo album, his gaze immediately fixated on it. On the first page of the notebook, there were four symbols: SOHX. There was no text description, only a question mark at the bottom of each of the three letters OHX. What did that mean?

Then, he opened Su Heshan's notebook. The desktop was very clean, and apart from the necessary office documents that were initially installed on the computer, there were only two prominent word documents. One of the word documents was titled "A Strategic Study of Hsiangheng (Group) Corporation's Span Development". When he opened it, he found that the contents were the graduation thesis written by Su Heshan. The thesis was only partially written. The thesis includes the background of Xiangheng's enterprise and the introduction of founder Zhou Jinshan, the difficult conditions of its initial establishment, the scale of its current development and the scope of its expansion. Next to this document, Su established another encrypted word document, named Fluorine, which walks toward the dining table. As for what was written in the document, Shen Yuan did not know. Fluorine is a toxic element. Usually, the amount of fluorine in the food does not exceed the standard. Why did Su Heshan's article put the two together and encrypt it?

That night, Shen Yuan did not sleep well.

The next morning, Shen Yuan woke up early. The Suzobers had grown much older overnight because of their grief. The two of them shut themselves in the courtyard, unable to extricate themselves from the pain of losing their girl.

"Where did Su Hai Shan go to take pictures of the scenery?" Shen Yuan asked Su Zuo Bo.

"She's been in a lot of places. When she got home at the end of the year, she went out a lot and took a lot of pictures just on the two banks of the Lai River, where the bird island was her starting point. " Suzobo said.

"The lower part of the Lai River that starts with Bird Island?" As Shen Yuan spoke, he took out Su Heshan's sceneries book and placed the photos on the ground. He discovered that the Lai River flowed from the upstream of Bird Island to the downstream of Autumn Cloud Manor. The river was shaped like an S.

Shen Yuan immediately thought of the four letters' SOHX 'and asked Su Zuo Bo where these letters might represent the terrain.

Souzober told him that the island was at the upper end of the S-shaped island, and that the water surrounding it formed an O shape. As for that "H", it should have represented the village of Autumn Cloud, which had a tributary at the lower end of the Lai River. As for what the "X" represented, he could not figure it out for a while.

Had Su Heshan been killed while photographing the scenery at "O"? If he was not killed, Shen Yuan speculated, could Su Heshan's next target be Qiu Yun Village or somewhere else at H?

What did "X" represent? Shen Yuan remembered that Su Heshan once said that she wanted to go to the Goose-Ridge Valley to take a picture of the scenery. He then asked Su Zuo, "What kind of place is Goose-Ridge Valley?"

"Oh right, I remember now, X represents the Goose-Ridge Ditch. Beneath the Goose-Ridge Ditch was a canyon in the four directions of East, South, West, and North. Entering from any one of these canyons would allow one to reach the mountain in the middle. The mountain in the middle looks like a penguin. " "It's on the border between Qinglong and Ji Zhou, and the mountain is very dangerous."

Shen Yuan was determined to explore the Goose-Ridge Ditch to find out what Su Heshan thought about the 'X'.

Starting from Green Dragon Town, he took a boat across the Lai River, crossed the Yue Tian Village, and followed the mountain road for five kilometers until he arrived at an entrance on the east side of Goose-Ridge Valley. The Goose-Ridge Valley has a mild climate and abundant rainfall all year round. In addition to Hunan Province's barite production base, there is also the "South China's First Spring" known as the Goshing Hot Springs Scenic Area. The Zangling hot spring is a typical sulfate spring. The water temperature is constant at 38-39 ℃ and the water quality is clear. Every winter there is an endless stream of tourists coming to soak in the hot springs.

Shen Yuan carefully walked along the small and narrow path on the right side of the mountain, heading towards the summit of the Goose-Ridge Valley. The deeper they went, the more beautiful the scenery became. Walking on the narrow road, there was a sense of desolation isolated from the rest of the world. He raised his head and saw that the surrounding mountains were blocking his view. There was only a piece of blue sky hanging above his head.

This was the first time that Shen Yuan had experienced the taste of a "frog in the well".

If he continued to walk deeper, he would occasionally discover many small holes. The cave would emit an unpleasant gas, mixed with yellow smoke and a large amount of hot water vapor. Shen Yuan speculated that there was an underground river and a huge heat wave at the bottom of the mountain. Heat evaporates the water in the ground and dissolves some of the less stable substances to release gas. The composition of the gas should be complex. In addition to pungent sulfur dioxide, it also contains sulfur, water vapor, carbon monoxide, carbon dioxide, etc.

Arriving at the top of the mountain, Shen Yuan followed a very dangerous path and slid down the other side. Both sides were weirdly shaped and had an imposing manner. The stone wall above his head seemed to want to open up, the stalactites hanging from the ceiling seemed to be on the verge of falling down, causing one's heart to palpitate. Shen Yuan did not even have the courage to raise his head and look up. He only had his head lowered, rushing forward as if his life depended on it. But the narrow, bumpy road had limited his running speed. Soon he was sweating profusely. About 20 minutes later, they entered a stone room that resembled a stage. Shen Yuan sat down, feeling safe and comfortable. Through the small hole above the stone chamber, he could vaguely see a zigzag shaped river at the foot of the mountain. The beautiful scenery of the river bank was endless, like the beautiful scenery of the Lijiang River.

It should be said that this was an excellent place to take pictures of the S-shaped Lai River. Had Su Heshan ever been here before?

After a short rest, Shen Yuan continued on his way. Not long after, they passed through another pile of rubble and entered a seemingly barren piece of land. The ground was covered in overgrown bamboo and there was a small stream flowing between them. It was extremely quiet. After they passed the bamboo forest, they would see the criss-crossing stalagmites. Further ahead was a cliff. At this point, there seemed to be no other way.

Shen Yuan took a closer look, there were many green vines on the cliff that were as thick as fingers, intertwining and intertwining with each other. Shen Yuan looked at the torrential river below the cliff, and made up his mind. He grabbed onto the vine, and started climbing down the cliff.

Although this cliff was very steep, there were many stalagmites growing out from the cliff wall. As a result, he only needed to gently grab onto the ivy and step on the stalagmites. It wasn't difficult to climb down. After descending about ten meters, a long and narrow hole appeared on the wall. It was about ten feet long and six feet wide. The interior was pitch black and its depth was unknown.

Shen Yuan entered the cave and used the flashlight to illuminate the stone wall. A few brown geckos quickly escaped. The cave was relatively dry, and there were no traces of wet moss on the ground. The stone tunnel extended into the darkness.

The deeper they went, the hotter the cave became, and the ground also became wet and slippery. One could see moss growing on the walls, probably due to the lack of sunlight and the inability to perform photosynthesis. The moss was grayish white.
