"Now the construction team can start work normally."
Although there was only one excavator and one transport truck, the combination of the two already formed a simple cycle, truly promoting the continued operation of the excavation project.
But even so, it was still not perfect enough.
The soil at the site Su Wu chose for the shelter was relatively soft. Digging underground space wasn't difficult, but correspondingly, the risk of collapse during construction increased significantly.
Therefore, the process of reinforcing the underground space had to be carried out simultaneously with excavation. There was no room for negligence.
Looking at the slope dug out by the mini excavator, Su Wu couldn't see any issues for now due to the short digging distance.
But he knew that if left unchecked, the mini excavator would continue digging, and there was a high possibility it could end up buried in the soil.
Returning to the bedroom, Su Wu opened his laptop. In one go, he continued adding tasks to the engineering robots, including manufacturing construction robots and small cement mixers.
Neither of these manufacturing tasks was difficult.
Several hours passed.
After investing another five survival points in upgrades, a humanoid construction robot appeared in front of Su Wu.
Compared to engineering robots, construction robots were extremely cheap—only one-third the cost of the former.
Their design was more human-like, with two robotic arms ending in bionic fingers capable of flexibly using various human construction tools.
Occasionally, they could also be used for carrying goods or even as bodyguards.
It could be considered a standard multi-purpose worker.
The emergence of construction robots truly made up for the last shortcoming of the engineering team, completely freeing Su Wu from manual labor.
At the very least, unlike before, Su Wu no longer had to personally break open the courtyard wall. He only needed to give the construction robot a command, and it would complete the task automatically.
"Go reinforce the passage."
Su Wu assigned tasks to the construction robots.
By this time, after nearly a day of excavation, the mini excavator had already dug out a decent entrance to the passage in the yard. It just needed reinforcement.
For temporary reinforcement, wood was the best option—it was cheap and fast.
However, since Su Wu couldn't buy any at the time, he had no choice but to use steel angle irons instead.
In this approach, waste was a secondary concern.
The key issue was that the engineering robots had to allocate time to cut and weld suitable plates, indirectly affecting other manufacturing tasks.
"What a pity! If only I could go to the mountains and cut down some trees."
The city's suburbs had no shortage of barren mountains and wilderness. However, since social order hadn't collapsed yet, even knowing that doomsday was approaching, the chances of those forests surviving were slim. Cutting down trees at will was still out of the question.
Feeling regretful for a moment, Su Wu quickly calmed down.
There was no need to be too greedy.
His current situation was already quite good. He had an extremely efficient construction team that could work 24 hours a day and his own site to build a shelter.
He was far ahead of most people.
The truly miserable ones were the ordinary people living in the city, oblivious to the impending doomsday. When the time came, they could only hope that the official shelters had enough space to accommodate them. Even if they were lucky enough to get in, the quality of life there was predictable.
By evening, the yard was brightly lit.
Two robots and two engineering vehicles worked non-stop to dig and reinforce the underground passage.
The scene was bustling with activity.
To avoid interfering with construction, Su Wu stayed in his bedroom on the second floor early on.
While remotely monitoring the construction progress through the control software on his laptop, he also played games out of boredom and browsed forums and news online.
"The temperature in Antarctica has risen, breaking historical records. Millions of cubic kilometers of glaciers may melt, and over a hundred coastal cities could be submerged."
"The strongest typhoon in history is about to make landfall on the Dongzhou coast."
"Starting at 8 o'clock tonight, all production and work in Poxiao City will be suspended in preparation for the typhoon."
Several disaster reports entered Su Wu's field of vision.
Similar news had appeared every year in the past. Generally speaking, unless one was at the epicenter of a disaster, most people wouldn't feel anything special about it. They would simply treat it as another environmental warning or weather forecast.
But with a little attention, it became clear that today's news was subtly different from before.
Words like "record-breaking" and "strongest," carrying strong ominous undertones, appeared frequently, as if they were being given away for free.
"The signs of doomsday are becoming more and more obvious."
"Will the first wave of doomsday climate disasters be extreme heat?"
Su Wu clicked on the news, watching videos of massive Antarctic glaciers collapsing into the sea, feeling a faint sense of awe.
He had deliberately chosen to build his shelter in the continent's central region.
The main reason was to avoid possible tsunamis and rising sea levels.
Factors like stable geology and low land prices were only secondary considerations.
Now, it seemed that this decision had been absolutely correct.
At the very least, his location had a high probability of not being the first place to experience doomsday.
This gave him more time to prepare.
"It's a pity for those in coastal cities. I wonder how many will survive in the end."
Another news update popped up. The accompanying image showed a city where waves crashed against the embankment while children played along the shore.
Su Wu could almost smell the scent of death.
But there was nothing he could do about it.
Without the warning from the Doomsday Survival System, he would have been just another ordinary person living in a coastal city.
After reading the news, Su Wu opened his communication software.
A few days ago, to assist in planning his shelter, he had joined a large chat group of survival enthusiasts.
He had learned a lot from them.
At this moment, in their view, his concerns were completely overblown.
"I suggest you take a look at how many regulated goods are already on the market."
"It's actually very wise to leave the coastal areas as soon as possible."
Su Wu thought for a moment and replied to Chen Xin with these two sentences in the group. Then, ignoring the multiple objections that popped up afterward, he closed the group chat and focused on his game.
If just two sentences could save a life, he wouldn't hesitate to say them.
But if the other party was too foolish and ultimately chose to follow the crowd, Su Wu wouldn't regret it.
Whether human civilization could survive in the apocalypse remained to be seen.
The foolish would simply perish.
