Stopping down, Su Mo began to look around.

Along the way, Su Mo felt a noticeable fluctuation as he lay flat on his stomach.

"If I'm not mistaken, I'm in a basin."

They were three kilometers away. Looking at the road they came, the distance had become blurry, and the horizon had hidden part of the scenery.

Looking west, he could feel the slope of the terrain rising.

After taking a good look around, Su Mo found the site of the ruins.

"Is... this where the prehistoric ruins are?"

It was a terrain almost identical to the shelter.

There was also a small hill where the underground ruins were located. There was no perfect drainage facility around it because of the terrain, which led to the large pools of water.

Of course, if there were no markings on the map and the existence of the ruins, it would be the perfect place to build a shelter by choosing it as the foundation and adding pipes to clear the water.

"Woof woof woof!"

Oreo retreated from the distance and asked his master for advice.

Because of more than a day of heavy rain, the water near the ruins was so deep that Oreo could not cross it even in his raincoat.

Looking at Oreo's frightened expression, Su Mo said without hesitation.

"We have to figure out this shelter. It's the only known treasure spot near us. Wait here for me. I'll go there alone."

"Woof?"

Oreo wagged its tail, not wanting to be separated from its master.

Bending over and rubbing Oreo's head, Su Mo comforted it.

"Don't worry. Keep watch for your master outside. The acid rain inside is scary. Once you touch it..."

"Hiss! Your fur's gone!"

Oreo, who was still eager to have a try, was immediately shocked by Su Mo. Its eyes showed a feeling of fear, grievance, and reluctance to part with him. It simply stayed squatted in the same place and shook its big tail.

Standing up, Su Mo took a deep breath, pulled out his raincoat from the storage space, and started putting it on.

The flowing raincoat did not hinder regular movements at all. After inspecting to ensure there were no leaks, Su Mo began to wade through the water one step at a time.

It was still about two hundred meters from where the hill was.

The water level was over his feet.

As a precaution, Su Mo decided to walk around the hill to get behind it and try to explore in a direction that was less prone to the water pooling first.

The plain soil had never been solid had become mud under the rain.

Su Mo walked every step with great difficulty.

A small part of his leg would even get stuck sometimes, and he had to spend a lot of effort to pull it out.

Wading through the water, he walked for about twenty minutes only to have gone around a hundred and fifty meters.

As they reached higher terrain, the soil began to harden, and the water gradually disappeared.

However, various footprints on the ground made Su Mo tense.

The footprints looked "fresh" and could be seen clearly in the heavy rain.

There were footprints split into two toes and a bunch of feline footprints.

A few hairs could be seen occasionally in the crevices of the soil.

Crouching on the ground, Su Mo carefully picked up the hair in the cracks and looked at it carefully.

"It does look like feline fur. With this flexibility, it's definitely not a regular animal."

With a restless heart, Su Mo clicked on the game panel and pressed Monster Illustration Handbook for the second time today.

[No mutant beast presence detected within a thousand-meter radius of the player.]

[Today's count 1/3]

"That's strange. In theory, felines should be very territorial. This can't be its territory."

Felines used claw scratches and urine to mark the boundaries of their territory and tell other animals when they passed to avoid accidental meetings and conflicts.

After looking around, Su Mo shook his head. He could not find markings nearby.

"Is this blood?"

Touching the side of the hill, Su Mo found a pool of blood that had seeped into the ground.

He lowered his head and smelled the smell of the ground. Other than the stench of the earth after a rainy day, he could smell a trace of blood.

There was also a lot of hair near the blood.

And...

A place that had been bombarded.

"What's this? Holy shit, was this bombarded by a grenade?"

The further he went to the side of the hill, the more traced of animals there were.

When Su Mo got around to the left, he was shocked to see scorched marks on the ground.

The grass beside the marks was still green, but nothing was growing in the center of the marks.

The area that was bombarded was extremely unusual. According to the diameter of the center of the explosion, it was only about 50cm.

Besides, the land was not blown up, which made no sense for a fixed-point bomb or a hand-thrown grenade.

Su Mo felt had a bad feeling.

He walked quickly back to the middle of the hill and walked to the top of it. As he neared the end, there were more bombardment marks.

Besides, a big dark hole was blasted out at the front.

"???"

"Did someone get here first?"

Fetching a flashlight from the storage space and turning it on, Su Mo peered into the hole.

It was more than four meters from the hole to the ground. It was almost the same height as the shelter. The building here gave Su Mo a sense of familiarity.

"Why does it feel so intensely familiar? Is this not a human shelter?"

If this were an RPG game, there would be countless questions marks hanging over Su Mo's head.

'How about getting down there to check it out?'

A bold idea flourished like crazy after popping out of Su Mo's mind.

Everything here was too strange. The inexplicable feline fur, the small bombardments at several points, and the design of structures that mimicked a human shelter all added a sense of mystery to the underground ruins.

After opening the storage space and searching around, Su Mo decided to use the original method of weaving a hemp rope.

It was more than four meters high. It was easy to jump down but difficult to come back up.

Taking out two units of plant fiber and sitting at the hole, Su Mo began to weave the hemp rope.

In less than 20 minutes, Su Mo had woven a rope about three meters long by repeatedly winding strands of tough plant fibers down it.

Taking out two units of iron and putting them on the ground, he tied a section of the hemp rope to the iron, and a simple up and down device was completed.

At this moment, Su Mo was glad that he had joined a DIY craft club in college.

Otherwise, this simple job would have been a little difficult for ordinary people to do.

After putting away everything, Su Mo tried throwing pebbles around. After making sure that there was no mechanism, Su Mo began to explore the ruins for the first time.

He had read a lot about tomb raiding in novels, but it was difficult to actually do it.

Awkwardly biting the flashlight in his mouth, Su Mo grabbed the rope and began to slide down.

The rough touch of the plant fibers greatly increased the friction of the slide. Su Mo had to put a lot of effort into getting a good grip of it in each slide.

When there was only one meter left, Su Mo released and naturally fell to the ground.

After holding his breath for a long time, Su Mo gasped heavily as soon as he recovered.

However, when he lifted his head and looked ahead by the light of his flashlight, he felt a thump in his heart.

One person (×)

A skeleton (√)

He had just got rid of five hoodlums last night but looking at a skull that had fallen on the ground looking sideways at him.

There was a burst of cool air behind him.
