Doomsday Game: Buy the whole world from the subway station

Although it has only been a day, Tang Yu has clearly felt that the price of thermal insulation materials has increased significantly.

Yesterday you only needed a long gun to trade for a rare item, but today the price has doubled or even tripled.

Obviously, today's sharp drop in temperature makes all survivors understand that the extreme cold disaster seems to be coming earlier than expected.

However, Tang Yu was not dissatisfied with this. He had expected this before.

He was extremely glad that he had made the right decision before and was able to trade a large amount of needed supplies while everyone was entering the early stages of the doomsday.

Therefore, Tang Yu was very liberal in terms of the amount of this transaction. As long as the other party was not a lion and the demand was within a reasonable range, Tang Yu would choose to trade.

He also focused on the upgrade materials needed to build the facility.

It took a whole morning to finish digesting all the weapons and equipment.

In addition to obtaining a large number of materials and food reserves needed to upgrade the hideout, and a large number of doomsday coins.

Tang Yu once again obtained several good rare props or construction drawings, including a hideout upgrade drawing, which satisfied Tang Yu the most.

But in exchange for this drawing, Tang Yu consumed at least about one-tenth of the trading items.

But in his opinion it's quite a bargain.

[Hideout Upgrade Drawing-Underground Air Raid Shelter]

Type: Rare drawings

Effect: After use, the survivor's hideout will be spatially upgraded and transformed.

Upgrade requirements: [Hideout] required, stones x300, concrete x20, waterproof glue x5, foam glue x5, alloy steel x20, doomsday coins x100,000

Upgrade time: 5 seconds

The upgrade materials have met the conditions. Do you want to upgrade?

Tang Yu had arrived outside the hiding place at this moment and made a decisive choice.

【yes】

I saw the entire hiding place in the dark subway station, which became even deeper.

Five seconds passed quickly. When Tang Yu opened the door of the hiding place again, the appearance inside the door had changed drastically.

What was originally a short downward staircase became longer.

After walking down about three meters, Tang Yu stepped on the ground of the hiding place. The hiding place was still in an "L" shape.

After walking through a security corridor of about 3 meters, you will arrive at the lobby of the hideout, and this security corridor is right at the corner of the 'L'.

Tang Yu looked inside.

The roof has changed from the flat roof of the station control room to a vaulted roof, just like the roof of a cave dwelling.

But the internal area of ​​the hideout is more than twice the previous area.

The rest area, kitchen, ventilation ducts, generator sets and other hiding place facilities are still in their original positions, but there is a lot of space between each facility, which should be left to facilitate future facility upgrades.

And the size of these facilities has been correspondingly changed with the upgrade of the hideout, making them look more coordinated.

The only big change is the ventilation duct. Originally, the ventilation duct was installed above the roof with an approximately 30x30cm vent.

At this moment, we reached the top of the longer wall of the hiding place "L", and the one vent became three.

So even though he is underground now, the air in the hiding place is still very fresh.

Tang Yu looked at the data given in the virtual map. Originally, the subway station was underground. At this time, the hiding place was already 30 meters away from the surface.

"This hiding place should be enough for the time being."

After briefly looking around the hideout, Tang Yu began to build other facilities.

Tang Yu carefully selected the facilities drawings of these three hiding places, and the rest area renovation drawings - the fire kang began to be transformed directly.

Then, we built the [water collector] facility next to the kitchen. However, since we had all the materials for construction this time, we chose to build it directly.

Originally, Tang Yu was not in a hurry to build the [water collector]. Now, he had enough water for himself. The various bottled water or milk in the warehouse were enough for him to eat and drink for a week.

However, after seeing the two facilities, the water purifier and the heat reducer, he still chose to take them.

Just treat it as preparation for the future, it will be used sooner or later anyway.

On the other hand, the price of these two blueprints is really too cheap, which is the price of a long gun.

However, Tang Yu also knew the reason. The traders of these two rare blueprints were survivors in the urban area, so the demand for water sources was definitely not great at this stage, and the construction requirements of these two blueprints were very demanding. Survivors who could meet these needs at this stage could be said to be very rare.

So it would be more cost-effective to trade weapons with Tang Yu, and weapons were definitely hard currency that was still durable at this stage or even after the first disaster.

Although Tang Yu has been trading weapons these days, there are still very few survivors who rely on themselves to obtain guns at this stage.

Half an hour later, the [Water Collector] was built.

Tang Yu directly chose to use the two rare blueprints of the water purifier and the heater.

During this period, the warehouse upgrade had been completed long ago, and the warehouse space was directly expanded to 200 slots.

It seems a lot, but because the items in the doomsday game occupy different numbers of slots, only small and cumbersome things are placed in the warehouse.

For example, food, drinking water, medical supplies, etc.

And the generator fuel he bought was neatly stacked in the corner on the other side of the hiding place. This time he traded about 20 barrels. According to the consumption of one barrel per week, it is enough for him to use for a long time.

This was a trade by a player who happened to be born near the gas station.

Coincidentally, this person and Tang Yu are in the same area, that is, the buddy who placed the hiding place in the sewer before.

I heard that this buddy made a lot of supplies by reselling fuel.

Tang Yu couldn't help but sigh. Sure enough, there are many capable people. As long as they are good at discovering, they can always find ways to benefit themselves.

When Tang Yu piled up the wood, charcoal and other materials needed for the kang in the corner.

It was already 2 o'clock in the afternoon, and the upgraded facilities were all upgraded.
