When the quick-drying cement sealed the last gap in the exit, Yu Yuan showed a look of relief.
"I finally sealed this exit shut!"
According to the instructions for the quick-drying cement, it would fully harden within an hour at most.
Then he would only need to press blast-resistant sandbags over the cement and use the truck tarp beneath the exit cover as a waterproof barrier. There should not be any problems.
Carrying his tools back, Yu Yuan saw that the only passage outside the shelter's door had already been blocked by a 1.2-meter-high wall of blast-resistant sandbags. The waterproof sheet found at Phoenix Tree Apartments was wrapped around the outside of the sandbags, providing additional waterproofing.
The corners on both sides of the wall and the gaps in the floor had been filled with quick-drying cement, reinforcing the sandbag wall while completely eliminating any chance of rainwater seeping through.
Unlike the exit he had just sealed, however, the quick-drying cement here had already hardened.
Yu Yuan kicked it twice. It was rock solid, and a smile appeared at the corner of his mouth.
He then carefully inspected the gaps between the sandbag wall and the surrounding walls with his flashlight. Once he confirmed there were no problems, he climbed over the tall sandbag wall and entered the shelter.
It was already two in the afternoon.
After a full day and night of relentless running around without sleep or rest, Yu Yuan was exhausted beyond measure, but it had all been worth it.
Of the two exits in the air-raid shelter level, one had been completely sealed. He only needed to wait for the quick-drying cement to harden before pressing blast-resistant sandbags over it.
As for the ladder exit he used frequently, all the sealing materials were already in place. If necessary, he could finish sealing it in less than half an hour.
And that was only Yu Yuan's first line of waterproof defense against the typhoon.
The second line of defense was naturally the tall wall of blast-resistant sandbags in front of the passage. Even if rainwater seeped in through both exits, that wall could still stop it from spreading.
The third line of waterproof defense was naturally the optimized [Stainless-Steel Floodproof Door] in front of him.
[Security Level 2—Stainless-Steel Floodproof Door] Quality: Excellent Function: Security level +4. Resistant to backflow, corrosion, seepage, sound, and impact; includes a locking function.
Not only did the floodproof door's frame have silicone waterproof strips, but an automatic water barrier had also been installed along the bottom. The hinges and lock no longer resembled their previous appearance at all; they had all become stainless steel.
A waterproof slope had also been made outside the door, and waterproof sealant had been applied to every seam between the frame and the wall. As long as the door was shut tight, the silicone seals in every gap would automatically close and adhere. Not a single drop could get through, so waterproofing would not be a problem.
Yu Yuan nodded slightly. Excellent-quality [Security] was the first optimized facility he had built.
He had done everything he could with these three waterproof defenses.
If there was still anything lacking, it was that the shelter's walls had not been waterproofed. But that was not a major issue.
Back in the shelter, Yu Yuan lay down on the floor bedding and felt aches all over his body. Even the slightest stretch of his limbs made his joints crackle.
Constructing facilities in the shelter only required materials, and the construction could be completed in a single step.
But sealing the air-raid shelter exits and building the second waterproof wall had required him to do everything himself, brick by brick. Carrying hundreds of blast-resistant sandbags and applying the quick-drying cement had long since drained the last bit of strength from his body.
He did not even have time to eat. As drowsiness washed over him, he only managed to set the Positioning Watch alarm for six in the evening before falling into a deep sleep.
Ding ding ding...
Yu Yuan felt as though his head was splitting apart. He seemed to be trapped in endless darkness, wanting only to sink deeper into it.
So tired!
I'm really tired!
Sleep!
I want to sleep!
Yet within the hazy darkness, the ringing grew clearer and clearer, gradually rousing his consciousness.
He struggled to open his eyes.
At the request of many readers, an ad-free VIP membership feature was now available.
Tap to view.
Looking at the soft candlelight in the shelter, Yu Yuan's mind was still muddled. It took another three seconds before he slowly came to his senses.
"This... this is the alarm I set..."
He turned off the alarm.
He felt that more than half his strength had returned. Although his body still felt hollowed out, he was much better than before.
He forced himself upright and patted his cheeks to clear his head.
After lighting a cigarette, the sharp, spicy irritation in his lungs finally restored some of his spirit.
It was already 6:05.
After quickly replenishing some food and water, Yu Yuan took out the hand-crank flashlight. He cranked it for a while to generate power, then left the shelter to inspect the exit he had sealed earlier.
Clang, clang, clang...
The back of the kukri struck the cement, producing crisp sounds.
A smile filled Yu Yuan's eyes. After nearly four hours of setting, the cement had completely hardened. He immediately spread the sandbags he had prepared evenly over the cement-covered wooden board. The sealing of this exit was finally complete.
Back in the shelter, he checked and equipped the kukri, Glock 17 Pistol, twenty spare rounds, alloy folding hand crossbow, and backpack in turn. He was fully prepared to set off.
There was about an hour left before Marauder Prison ambushed the Black Shield Police Department.
His purpose this time was to fish in troubled waters and look for a chance to profit. He would travel light and keep things simple.
For that reason, he had specifically cleared out the supplies listed on Taotao Cave and prepared another bundle of grass for the Kerry Hill Sheep.
Stroking the Kerry Hill Sheep's head, Yu Yuan muttered, "This is the last chance. Bless me so I can catch a woman during this operation! Once that happens, you'll finally be free."
Before leaving the shelter, Yu Yuan suddenly stopped. He opened Taotao Cave, tapped around for a moment, and completed two transactions.
He spent 75 Survival Points to buy stone ×10 and wood ×5, then added nail ×5 and steel ×1 from the shelter.
He immediately began construction.
Thirty seconds later, a one-meter-square fire pit appeared on the shelter floor. Stones surrounded the pit, with wood in the center and a stainless-steel tripod standing above it.
As long as he lit the wood, he could use the tripod to boil water, make soup, or... barbecue.
This was the new facility, [Kitchen Level 1—Fire Pit], unlocked after [Ventilation] and the [Water Collector] had been built.
Function: Energy level +1, comfort level +1, hygiene level +1. While burning, the shelter's indoor temperature increases by 5°C, while the temperature within two meters increases by 15°C. Unlocks [Food Preparation].
Joy appeared in Yu Yuan's eyes. Three +1 bonuses.
"It wasn't easy! I can finally have a hot meal."
With that thought, he blew out the candle and left the shelter.
Golden Orchid Avenue in District 14 was a famous, bustling commercial district in the eastern part of the city. Before the wasteland era, countless luxury cars came and went here.
Especially the Land Hotel at the intersection of Golden Orchid Avenue and Waterfront Street. It had once been one of Green Forest City's most luxurious hotels.
Countless tycoons, politicians, financial magnates, movie stars, socialites, royal family members, and gang bosses had passed through its doors. It was a symbol of status and standing, as well as a threshold between social classes.
This place had once been Green Forest City's most dazzling sight.
Unfortunately, the current Land Hotel was merely a relatively recognizable building among the ruins of the wasteland city.
At that moment, inside a sewer at the corner of Golden Orchid Avenue, Yu Yuan stood on a ladder with his head tucked down, listening to the sounds outside.
With some effort, he checked the time—7:15.
There were still fifteen minutes until the conflict was supposed to erupt, according to the intelligence...
