Doomsday disaster: Start by building a shelter

Day 2.

Su Wu had been awake for nearly a night.

With a somewhat tired spirit, I returned to the bedroom to catch up on my sleep.

The difficulty of studying the system of electrical energy equations.

Exceeded expectations.

After investing a lot of spiritual energy in the follow-up.

After a whole night, Su Wu could only advance the research progress to about 16%.

Moreover, this also made him realize a reality.

Not in the same 10 minutes, the more spiritual superpositions you invest.

It can bring more research progress in the same proportion.

After a certain level, it has a diminishing return effect.

Specifically, it comes to the basic theoretical technology of electric energy equations.

The way to use it with the highest return rate is to triple the spirituality.

That is to say, when consuming 3 points of spirituality every 10 minutes, the most cost-effective way to improve research progress is.

A little more, a little less, it's not as cost-effective.

In addition to this.

As the spirit becomes tired, the blessing effect brought by spirituality will quickly fade.

This means that there is also a limit on the maximum time that spirituality can be used in a day.

"It's still because of poverty."

"If you are spiritually rich enough, you won't have this kind of trouble."

Su Wu felt a little pity.

This feeling is just like the difference between using a monthly card to receive game coins every day in a card drawing game and directly earning game coins.

The latter has no time limit and is purely a matter of money.

The effect is there.

The cost will be so huge that it makes ordinary people feel distressed.

In contrast, it is more cost-effective to extend the timeline and use a monthly card.

However, although there was a slight setback in research.

But through the technology tree, the research progress of 16% can be found.

In itself, Su Wu still felt quite excited.

This means that his previous investment has not been wasted.

Next, it’s just a matter of continuing to invest.

Considering the current stable environment on the surface.

Time was on his side.

"Take your time."

"It's not too late."

The next few days.

When Su Wu was fine, he would provide spiritual blessings for a period of time.

Used to study electrical energy equations.

At the same time, I also asked Chenxin sisters to try it.

However, their effects were much worse than Su Wu's.

Su Wu dedicated some time to find out the reason.

Discover that spirituality actually has a hidden rule.

It has no restrictions except on Su Wu himself.

When applied to other people, it also needs to be based on that person's relevant talents in order to be effective.

For example.

Chen Xin has a high talent in the field of chemistry. When studying chemistry-related technologies, he can 100% exert the effect of spiritual blessing.

But once the technology is studied, it has little to do with chemistry.

The effect will be reduced accordingly.

The minimum effect may only be about 50%.

This kind of waste was simply unacceptable to Su Wu, who was not wealthy.

So after testing it once.

Su Wu simply decided to do it himself.

Anyway, the final result will not be less than a few days, so there is no need to be so extravagant and wasteful.

And while Su Wu was busy with research.

The manufacturing center completed the production of 3,000 spider robots.

After all were delivered to the remote control center, Su Wu's transportation capacity reached a peak.

More than 70,000 tons of supplies can be transported out of abandoned underwater shelters every day.

Suwuna has added nearly 2 million tons of resources.

This is no longer data that only exists on paper.

But actually, at a speed visible to the naked eye.

It has been greatly transformed into the real foundation that exists in each affiliated shelter warehouse.

September 9th.

The professional thermal power station located on the 9th underground floor of the farmyard has been officially completed.

Under the territory of Su Wu's power.

All other thermal power generators have since been eliminated and mothballed.

All affiliated shelters have begun to use electric transportation networks.

Uses electricity from specialized thermal power plants.

Thanks to these newly added overabundant power supplies.

The vegetable garden in the shelter, as well as the fodder growing area, receive the highest specification of sun light hours.

The growth rate began to increase significantly by nearly 30%.

Residents of the shelter.

There is no need to endure strict power usage restrictions anymore.

You can turn on lighting, TV, etc. to a limited extent in your dormitory at night. The cost of using washing machines in public areas has also dropped simultaneously.

The life experience has been significantly improved.

Also on this day.

The engineering team completed the expansion of the ninth floor underground of the farmyard.

Around the original ninth floor, an area of ​​4,850 square meters was added to the periphery.

Su Wu used all the additional area for building warehouses.

Finally, a 20,000 cubic meter reservoir, a 30,000 cubic meter metal warehouse, and an 8,200 cubic meter coal warehouse were divided.

At this point, all daily and industrial water in the Suwu shelter is covered.

They will no longer need to rely on the outside world.

It will also have a material warehouse that can store more than 200,000 tons of metal raw materials, and a fuel warehouse that can store tens of thousands of tons of coal.

September 10th.

After burning another 10 points of spirituality and superimposing the effect 10 times.

Su Wu used those 10 minutes.

The final breakthrough in the electric energy equations was completed.

Completely light it up in the tech tree.

Then, within half an hour after this theory was illuminated.

Su Wu only spent 6 points of spiritual blessing to complete the redesign of the solid-state battery.

It increases the storage power per unit volume by a full 10 times.

The emergence of this new type of battery.

This means that all of Su Wu's mechanical units will be able to escape the restrictions of electric transport vehicles to a limited extent when in the wild.

Standalone runs longer.

Reflected in combat effectiveness.

The most intuitive thing is that the comprehensive combat power has increased by at least 10%.

However, the technical iteration of solid-state batteries does not bring all benefits.

Its emergence means that the original electric transport vehicles will be eliminated.

The same body shape, even the cost is not much higher.

Electric transport vehicles using new solid-state batteries can store 100,000 kWh of electricity.

Equivalent to 10 old model electric transport vehicles.

And even if the old electric transport vehicles are dismantled and recycled.

Limited by insufficient existing technical capabilities.

The damage inside was staggering.

Probably only about one-tenth of this material will eventually be recycled.

This kind of invisible loss is even seen by Su Wu, who is now rich and wealthy.

There are also some shocking things.

"The price is really too high."

Seriously, when electric transport trucks actually come into use.

In fact, it hasn’t been long yet.

As a result, it has not played much role yet, and the value is directly approaching non-recyclable garbage.

It's really a bit hard to accept.
