The underground mine was an extremely mysterious and dangerous region.

Before the wasteland outbreak, this place had been frantically excavated, with the deepest parts reaching several thousand meters underground. The interior was winding and twisting with numerous branching paths—once you entered, nine times out of ten you would get lost inside.

Not only were there safety hazards left behind by previous people, but after the wasteland outbreak, many plant traps and well-camouflaged underground predators appeared. Underground hot springs and lava currents made every step treacherous here; the slightest carelessness could leave you utterly annihilated without a trace.

The Moss Cottage Shelter was situated right here.

Inside the shelter, glowing moss and luminous mushrooms were carefully arranged throughout the rooms, providing illumination.

A figure knelt on the floor, gaze intently fixed on the rough animal skin in front of him, a slight curve pulling at the corner of his mouth.

In the center of the animal skin was a box of Golden Fleece cigarettes, with a corpse of an unknown creature placed at each of the four corners.

A fish with no eyes, a big-eared rat, a long-legged spider, and a red-skinned bat.

A trail of blood from each creature flowed toward the center of the leather, but it seemed something was obstructing it—the blood twisted and turned, finally forming two blurred characters.

The moment these two characters appeared, a sharp light burst from the eyes of the kneeling figure, and the curve at his mouth reached all the way to his eyes.

"Indeed, it's still Yu Yuan after all. I knew this guy wasn't simple." Xiao Wu licked his lips, revealing the smile of a hunter who has spotted his prey.

"Is this the third or fourth time? In just three days, the total amount of cigarettes traded has reached over forty boxes... then the resources he controls definitely aren't small..." Greed flashed in Xiao Wu's eyes, but it was quickly covered by reason, replaced by a thoughtful expression.

"No, this guy is a bit strange. He's only been in the wasteland for one day, yet his shelter ranking has continuously jumped 501 places. It's very likely he opened a special path like I did. Need to be cautious, for safety's sake, better let others test the waters first."

"Unfortunately, that Cigar guy is cautious enough—he still hasn't shown his stance..." Xiao Wu casually picked up the eyeless fish and began tearing at it with his mouth.

The fish flesh, with a texture no less than tuna belly, made Xiao Wu narrow his eyes slightly, thoroughly enjoying it.

"Fortunately, there are those few guys doing the probing. Once the newbie protection period ends, we'll probably know the details of the Yu Yuan Shelter..." Thinking of this, Xiao Wu's brows furrowed together again.

"And that guy Raging Whale, ruining my plans several times in a row. The problem is this guy is slippery as an eel, impossible to lock onto... I need to think of a way..."

——————————

At 8:34 PM, after deliberately taking a long detour, Yu Yuan finally returned to his shelter. He dropped his backpack and immediately ran to the exit ladder of the civil defense shelter level, starting to block the exit.

First, he covered the exit with the truck tarpaulin, then fitted the pre-cut bed boards over the exit position, making them interlock.

With that, the exit was basically sealed. He then returned to the shelter, picked up a bucket to fetch water, quickly mixed the quick-dry cement according to the ratio, and performed the final sealing and filling of the exit gaps.

The quick-dry cement set very quickly, leaving Yu Yuan only 15-20 minutes to work.

Fortunately, he had practiced this once before, so the process proceeded methodically this time.

When he smoothed on the last bit of cement and carefully inspected all the gaps and openings, he finally let out a long sigh of relief.

This was all he could do; the rest would be about meeting challenges as they came.

Of the blast-proof sandbags he originally brought back from Wutong Apartments, aside from the twenty-plus bags he would later use to weigh down the exit bed boards, there were still over a dozen sandbag bags, all of which he arranged in front of the Security door.

"It's already past 9 o'clock now, about 6 hours until the typhoon arrives... I hope we can hold out!" Even though he had made ample preparations, Yu Yuan still felt somewhat uneasy inside.

Having witnessed the battlefield of the Thugs with a [Medium] danger level, he didn't dare underestimate this typhoon with a danger level reaching [High] in the slightest.

"No good, I need to further reinforce the shelter's facilities."

Yu Yuan entered the shelter. The Cree Mountain sheep came over and started bleating ~~baa~~ ~~baa~~ incessantly at Yu Yuan.

Seeing the green grass on the shelter floor eaten completely clean, along with those little round pellets.

Yu Yuan felt overwhelmed and frustrated.

He already had his hands full with his own mess, and now he had to serve this ancestor.

But he had no choice not to serve it. With the exit now blocked, this creature was his only hope for survival.

Originally, he had been thinking that if he could capture an injured female prisoner at the Landmark Hotel to eliminate the Indulgence Card, that would be great.

But in the end, forget women—he only encountered one living person, and that was a bald guy.

He helplessly glanced at the fire pit he had specially built earlier.

"What a shame!"

In the end, he opened Taotao Hole and discovered that, perhaps because he had continuously traded cigarettes for green grass, someone had actually listed green grass on Taotao Hole. It was still three kilograms traded for one cigarette, but some had also set it up for trading with survival points: 3 kilograms of green grass = 20, 10, or 5 survival points respectively—they were actually undercutting each other.

After all, the cost of green grass was almost zero; you could harvest a large bundle in two minutes, so selling any amount was pure profit.

Seeing this, Yu Yuan could only chuckle wryly at the situation, finding it somewhat amusing.

Naturally, he chose the cheapest trade, spending 100 survival points to trade for 45 kilograms before stopping.

This amount of green grass was enough for the Cree Mountain sheep to eat for a while.

After doing a quick clean-up of the shelter, Yu Yuan went to the fire pit, lit the firewood, used the stainless steel pot he had collected earlier to fetch half a pot of water from the Water Collector, placed it on the tripod to heat up, and began contemplating his next steps.

The most urgent matter was naturally upgrading the shelter facilities. Before the typhoon arrived, any upgrade he could manage would count.

He opened the virtual light screen, checked the construction requirements in the shelter's Facility Management Log.

Currently, he had already completed 7 facilities:

【Security Level 2 – Stainless Steel Waterproof Door】

【Rest Area Level 1 – Floor Bedding】

【Bathroom Level 1 – Washing Area】

【Ventilation Level 1 – Single Pipe Ventilation】

【Water Collector Level 1 – Faucet】

【Lighting Level 1 – Candle】

【Kitchen Level 1 – Fire Pit】

The shelter information was also much more detailed than initially.

【Yu Yuan Shelter】(Ranking: 9499th)

Owner: Yu Yuan

Area: 60㎡

Security Level: 6

Comfort Level: 4

Energy Level: 1

Defense Level: 0

Hygiene Level: 2

Among the constructible shelter facilities, 【Warehouse】, 【Leisure Area】... had also been unlocked one after another. However, these facilities wouldn't provide any substantial help against the coming typhoon disaster.

Although he was very interested in the 【Warehouse】, and he really did need a place to store supplies, now was not the best time to build the 【Warehouse】.

"With the fire pit and faucet, food heating and water source issues are solved. With three layers of waterproofing measures, the impact of the typhoon and heavy rain on the city's sewer system should also be manageable... but why do I still feel like I've overlooked something..."

Yu Yuan felt persistently uneasy.

"No, wait a minute..." He suddenly froze: "The sewer?"
