Cave Refuge

Dong Tianyu, who didn't get any significant haul, didn't go straight back. Since the original plan for the medicines had failed, he couldn't return empty-handed. The eastern district of Pengcheng was an industrial area where the Pengcheng Heavy Industries was located.

In just over twenty and less than thirty years, Pengcheng Heavy Industries had grown from a small factory to an industrial conglomerate, owning not only more than ten subsidiaries but also military enterprises.

If thirty years ago, Pengcheng's tax revenue depended on the coal mining group, then in these thirty years, Pengcheng Heavy Industries gradually overwritten the coal mining group's position in Pengcheng.

In order to upgrade the cave mansion as soon as possible, Dong Tianyu didn't refuse anything. Regardless of various industrial machinery or those basic raw materials, Dong Tianyu sent them all to the cave mansion for decomposition.

To upgrade the cave mansion as quickly as possible, Dong Tianyu simply didn't return to practice, but stayed in the industrial district for five days, having cleaned up most of the companies in the industrial area.

The reason why it was most of the companies was because Dong Tianyu didn't expect that despite the harsh external temperature, there were still companies operating normally.

But when Dong Tianyu observed closely, he found that this was a subsidiary of Pengcheng Heavy Industries, where the workers were enthusiastically modifying vehicles.

Seeing this, Dong Tianyu understood how the steam cars driving in Pengcheng came about.

He bypassed these still operating companies and cleaned out the other closed companies.

Now, there were less than a thousand survival points needed to upgrade the cave mansion, but Dong Tianyu only had over eight hundred survival points on his data layout.

Although after the last upgrade, Dong Tianyu could obtain five survival points per day, but even though he hadn't spent much survival points in these few months, there was still some consumption, such as for the puppet car, and for some modifications in the cave mansion.

Survival points in the cave mansion were a universal existence. As long as Dong Tianyu wanted something, as long as the number of survival points were enough, the cave mansion could satisfy any of Dong Tianyu's requests.

Seeing that he was getting closer and closer to the conditions for upgrading the cave mansion, Dong Tianyu thought about going straight to the Inner Harbor in the north district without returning to the Refuge Center first.

Pengcheng was not only a crucial transfer station for railways due to its geographical location at the junction of three provinces, but it was also connected to the Beijing-Hangzhou Grand Canal by waterway.

At first, there was only a Qianzhai Port here, which was just a small port. Its ability to transfer goods was far inferior compared to the land transportation ability.

However, when Pengville Port was completed, the role of Pengville Harbor suddenly increased, becoming one of the significant ports in the Beijing-Hangzhou Grand Canal.

Speaking of the port, inevitably leads to the topic of containers. When it comes to containers, Dong Tianyu thought of the famous foreign container treasure hunt program.

Every time he watched such videos, Dong Tianyu would imagine what his feelings would be when he opened the box. It had always been just an imagination, but now he could finally put it into practice.

Coming to the Inner Harbor of Pengcheng, Dong Tianyu didn't go to the warehouse of the container area first, but came to the harbor. Looking at the already frozen canal, Dong Tianyu curiously threw a stone onto the water surface.

As a result, the stone that hit the water surface was bounced off as if it had hit the ground.

Seeing this, Dong Tianyu knew that the water surface had already frozen solid, so he directly jumped down.

With his feet stepping on the solid ice, Dong Tianyu took out the puppet car and drove on the ice.

This was not because Dong Tianyu was idle and wanted to play, but after coming here, Dong Tianyu thought of the floods that would come after the cold winter. His Refuge Center was built halfway up a hillside, so floods should pose no threat to his Refuge Center.

However, the underground Refuge Centers in Pengcheng should all have been destroyed. Fortunately, there were many skyscrapers in Pengcheng, and those exceeding ten floors should not be flooded.

Compared to many residential blocks that have skyscrapers that are thirty to forty stories today, it should not be a problem.

However, compared to skyscrapers, it's much better to live on a boat when a flood comes.

It's just that the larger the ship, the more it depends on electronic equipment. After the destruction of the electromagnetic pulse, the ships in sleep have basically lost their ability to sail.

When the flood comes, these ships on the water surface will face two situations.

One is that the ship's anchor is very heavy. When the water level rises, the chain will not be long enough, pulling the ship into the water, and the cabin will be flooded, turning these ships into sunken ships.

The second is that the ship's anchor is not too heavy. When the water level rises, the buoyancy of the ship's hull will lift the anchor, and the unfixed ships will start to drift.

When the flood comes, whether it is a fishing boat or a one thousand ton cargo ship, the end result will basically be the same.

After all, by that time, others won't be needing them, so Dong Tianyu simply decomposed the ships left on the ice surface into the cave mansion to quickly upgrade the level of the cave mansion.

Actually, a cargo ship with a tonnage of about two thousand tons may sound huge, but in reality, it's only about seventy or eighty meters long and only ten to fifteen meters wide.

According to the area, it's actually about a thousand square meters. Excluding the cockpit area, the usable area is only seven to eight hundred square meters.

If it's used as a refugee facility to accommodate people, the actual number of people it can accommodate is less than the number of people a thirty to forty-story skyscraper can accommodate, and it's less comfortable than the high-rise buildings.

The ship's Refuge Center just occupies a mobile advantage, but when the flood subsides, these ship's Refuge Centers will be abandoned again.

Therefore, Dong Tianyu currently has no psychological pressure to take the ships on the water surface. After all, others won't need them, and Dong Tianyu simply decomposes them all to upgrade the level of the cave mansion.

After spending a day, there were only three ships left on the water surface.

The smallest one was a speedboat that could hold three to five people. The slightly larger one was a three-story tourist boat, the kind of small boat that could be easily rented for a sea trip in Sanya.

The remaining largest ship was the biggest one that Dong Tianyu kept after comparing all the ships on the water surface.

Moreover, this ship was not like a traditional river boat with a deep open cabin, but it looked like a sea ship with a fully enclosed cabin hidden under the deck.

Based on visual estimation, the specifications of this ship should exceed three thousand tons. While it's not like the coastal ports where there are easily ships over ten thousand tons, Dong Tianyu was quite satisfied with the ship in front of him.

Although the electronic equipment on board was completely damaged, Dong Tianyu planned to transform it into a mechanical ship from the mysterious side. Of course, it would be better if he could transform it into a Magic Artifact.

It's just that he couldn't put it into the cave mansion right now. After all, the length and width of the cave mansion are only about a hundred meters, and the length of this ship is estimated to be over eighty meters.

If it was forcibly put into the cave mansion, it would destroy the existing buildings in the cave mansion.

As for the Shadow Space, not to mention, Dong Tianyu, who has a hamster-like personality, despite the size of the Shadow Space being expanded eight times after the cave mansion was upgraded, he had already used up most of it.
