Wiping the rain off his mask, Su Mo pretended to shake his head and casually looked at it again.

This time, he saw it for real!

'These are human footprints!'

'These are not my footprints!'

Two ideas quickly emerged. Su Mo frowned, and his face darkened.

'There's someone near the shelter!'

Over the past two days, Su Mo also dreamed about having people near the shelter, and they could work together to build a harmonious home.

However, when traces of humans appeared near the shelter...

Su Moment only felt...

Uneasy!

He did not know where they were hiding or what their purpose was.

Doomsday! Mankind was the natural enemy of mankind!

Your house was a food bank if you accumulated food but not guns. However, everywhere was your food bank if you accumulated guns instead of food!

In a disaster of this magnitude, it was perfectly normal for someone to go crazy for resources.

At this point, Su Mo stopped hanging around. He opened the shelter's main door and slid inside.

The rain on the plains came down again and began to destroy all the traces Su Mo left.

Standing at the corner of the shelter, Su Mo held out his hands and waited for his raincoat to dry naturally before taking it off.

The heavy rain isolated the smell, which was why Oreo did not warn him.

After days of carelessness, Su Mo suddenly found the trace of human beings. Reflecting on it, Su Mo could not help but break out in a cold sweat.

"I just saw them talking about wilderness vagrant attacking civilians. I didn't expect them to find me."

"It's no wonder. My drains are too obvious in this wilderness. I wonder if this person saw me upgrading the drainage yesterday..."

"No, we can't sit back and do nothing."

Sitting down on the stool, Su Mo took a deep breath and suppressed the unease in his heart. His gaze turned grim.

"Oreo, come here."

He called Oreo, who was dozing off in the corner, and rubbed Oreo's soft head.

"Use your sixth sense and see if there's danger nearby."

Oreo understood the command, lay on the ground, and pricked up its ears to listen slowly.

A minute or two passed.

Oreo, who was smiling foolishly, changed its expression and began to sniff around on the ground. Finally, it gave a low bark at the southwest corner of the base.

"You mean it's dangerous in this direction?"

Seeing Oreo nod, Su Mo quickly began to recall what he had just seen in the southwest.

It was the direction of the base's drainage, with a small lake accumulating behind.

In the distance...

There was a shrub forest, and the trees were very green...

The more he recalled, the more Su Mo looked at what he had just seen from a third party's perspective.

Black!

A touch of black!

Suddenly, Su Mo thought of the black in the forest. It was different from the color of the trees, and he would not have thought about it without warning.

With vigilance, they found a clue at once.

'The shadow must have been about a hundred meters away from me. I didn't see them, but they must have seen me.'

'Oh no!'

Slapping his thigh, Su Mo subconsciously wanted to put on his gear and head over for a "friendly exchange".

The person must have discovered the fact that he was alone.

He could build a safe underground shelter and have a drainage facility that required a lot of work.

"I'm probably a fat lamb waiting to be slaughtered in their eyes now!"

Taking out the crossbow placed in the inventory, Su Mo laughed at himself.

The dark surface of the crossbow seemed murderous. With the light refracting, it revealed a black light.

"I didn't expect that the first creature my crossbow has to face is one of my own."

"I'll let you off if you don't provoke me. If you dare..."

Standing up and rubbing his brow, Su Mo walked over to the bedside and placed the crossbow on the bedside table.

The left side of the bed was about one meter away from the stone wall.

He summoned the creation page.

[Iron pickaxe: iron 1/2, wood 1/1]

The materials he had on hand fit the criteria.

Iron pickaxe was selected.

Confirmation to build!

[Record]: iron -2, wood -2

[Record]: Iron pickaxe (normal) has been successfully created.

An ordinary-looking but extremely useful iron pickaxe appeared in Su Mo's hand.

With a wave, Su Mo began to chip away at the stone wall near his bed.

It was hard to get in from the outside, but easy to get out from the inside.

Soon, the smooth stone surface was chipped away, and it gradually became a large hole that was waist-high as time went on.

Summoning the survival system to himself, Su Mo looked at the big hole.

[Passageway]

Description: Incomplete passageway

Upgrade option: Escapeway

Sections: Expansion (5), access (60), material (40), strength (200), door (40)

Introduction: A cunning rabbit has three burrows!

"You'll have to pay the price with blood if you want to ambush me."

Su Mo could not help but smile as he looked at the properties of the passageway.

Since he was now exposed, rashly walking out from the front door undoubtedly tantamount to delivering food.

In case of an ambush, he would be stabbed into becoming a porcupine the moment he opened the door.

Thanks to his wild imagination, Su Mo came up with a clumsy way to open a second path to the underground base.

His eyes relaxed, and the upgrade options disappeared.

They were not at the end of the line when the real intention was revealed yet.

Su Mo had always kept the bottom line against his own kind.

He would not attack unless they attacked him.

At the same time, he hoped they would not have to fight each other and encourage each other to survive Doomsday.

He watched Oreo wandered restlessly around the base, pricking up its ears to listen and lay on the ground to sniff from time to time.

Su Mo felt sorry and pity for it.

"Good dog. Wake me up if there's something wrong. I'm going to take a nap!"

After buying two pieces of mutant beast meat from the trading market, put them in Oreo's bowl, and added some psychic energy water, Su Mo went back to bed and slept in his clothes.

Daytime was not scary.

Nighttime was the time to blow the bloody horn.

He wanted to be at his best and keep watch at night, in case someone ambushed him at night.

The rain was still pouring like it wanted to drown the earth and destroy the world.

The world went silent under the rain.

Squeak squeak.

Half asleep, Su Mo dreamed that it was only a false alarm. No one had their eyes on his shelter or him.

Gradually.

The sky outside began to turn dark. The sun began to set, and darkness gradually struck from the horizon.

Under the cover of night.

Someone was coming.

Five dark figures crept up from the south side of the shelter, which was also the direction of the drains.

The five of them stepped on the stone-made water canals as they swore under their breath.

"Motherf*cker. This boy is so lucky to get the blueprints from who knows where, and now he's sleeping soundly in his shelter. Why didn't I have such luck?"

"Keep your voice down, Liu Ba. Don't f*cking expose us."

"What the f*ck are you scared of? He's just a young man with some luck. I'll be the first to kill him if he dares come out."

The man names Liu Ba not only failed to restrain himself but also became more aggressive.

"There's nothing we can do if he doesn't come out!"

Sitting on the far left, the short stealthy-looking man was able to see clearly, pointing out the problem they were encountering.

Su Mo's shelter was too solid!

It was so solid that the five of them were shocked the first time they saw it!

The stone main door was engraved with primitive patterns, which looked natural and embedded in the soil.

The drainage channels from the top of the hill to the bottom were made of stones, give the five people a shock beyond comparison.

"Boss Huang, don't you think it's a little unorthodox for us to do this? Why don't we just knock on the door and ask him to give us his supplies? Then we'll continue wandering."

The man with glasses, who was left behind by the team looked around as he walked. His face seemed gentle and quiet, but the words that came out of his mouth were rather brutal.

"Four-eyes, your hands didn't even tremble when you were killing earlier. Are you starting to panic? Are you scared?"

"Liu Ba figured it out today. There's only one softie in this shelter who got to live here because he was lucky. If we can get him to open the door and let us in, this place will be ours!"

The leader Boss Huang smiled scornfully. With the waist-high spiky mace in his hand, he could make children stop crying at night.

"How many supplies can we get by wasting our time in killing mutant beasts in one day? Have you forgotten how many supplies we've gotten by killing people these last two days? Use your brain and figure it out!"

"Could this person be harder to kill than mutant beasts?"

...

Inside the shelter, Oreo had woken Su Mo up from his sleep.

After letting out three or two breaths, Su Mo woke up and rolled out of bed.

He grabbed the psychic energy water at the head of the bed and downed it. Grabbing the crossbow, he got into combat mode in no time at all.
