Chapter 144

"Because of the subsidence of the terrain, although the wind from the upper layer can be transported down through the pipeline, the turbid gas will still settle. There is no air exchange system, which may be a serious problem for the underground shelter!"

When creating the underground safe house for the first time, the game panel indicated that the underground development potential was poor.

Among all the reasons, the most critical one is that it is very difficult to build the air exchange system at the bottom!

If ordinary people choose the underground, not to mention now, they need to open the door for ventilation.

Even in a few months, it is difficult to complete the construction of the air exchange window under the ground without mechanical assistance.

Therefore, in the first disaster, only sumo chose to go underground in the top ten shelters.

With the increase of the number of floors of the shelter, now after choosing the three-story design, even sumo feels a little tricky in terms of ventilation.

Back under the ventilation duct, sumo tried to call the system and check the properties of the duct.

[underground ventilation]

[description]: the crude ventilation device is connected to the three floors underground through a stone pipe to exchange air. The current channel pressure is insufficient, and the air exchange efficiency is low, which is easy to lead to hypoxia. Being in an anoxic environment for a long time, it is easy to cause brain burden. It is recommended to upgrade.

[upgrade direction 1]: increase the volume of ventilation duct, increase the pressure of ventilation duct, slightly enhance the ventilation efficiency, and slightly increase the air exchange efficiency. Survival is required (125)

[upgrade direction 2]: increase the electric air change device, greatly increase the ventilation efficiency, greatly increase the air change efficiency, and slightly increase the overall energy consumption of the shelter, which requires a front-end electronic control system and survival (00)

[evaluation]: Lu has to take a bite of the meal step by step. If he takes a big step, it's easy to pull the egg!

"Sure enough, the system also detected the ventilation problem on the third floor. In such an environment, even if there is no worry about life, in the long run, you will also suffer from anxiety and depression!"

If the brain cannot get sufficient oxygen supply for a long time, it will slowly increase the loss, making the thinking slower and slower, and the learning speed worse and worse.

Su Mo has seen this in a large number of scientific documents on earth.

Looking at the two upgrade methods given by the system today, after glancing at the number of remaining survival points, sumo began to think about options.

"The first is to treat the symptoms but not the root cause. If we need to add more floors in the future, it will be a waste of money, and we can't immediately solve the ventilation problem of the third floor."

"Second, the price is too expensive! I have to get enough survival points tomorrow. I feel a little lost investing so many survival points in the early stage."

Standing under the ventilation duct, sumo was in a dilemma.

On the previous floor, the air in the shelter was controlled by the lion's wind, and the effect was excellent.

Now it suddenly becomes three layers, and blessing immediately loses its immediate effect.

"The wind flows faster in the pipe?"

The voice fell, without a trace of movement.

I don't know whether it's the LV1 level or the blessing of the lion. This small-scale regulation can't be achieved at all.

"If the blessing power is infinite, you can find a way to use density to regulate the wind exchange."

"I have to test the limit of blessing first! See whether this power is used infinitely or consuming something I can't see."

Thinking so, Su Mo stepped through the corridor and returned to the first floor.

Standing in an open space in the garage, after adjusting the local wind to the extreme, Su Mo kept a record of the duration of the wind while packing up.

The biggest wind blew outside the garage, blowing all the snow at the door of the basement in the air.

Curious sparks, big and small, cooed, spread their wings and flew into the violent airflow, rolled up and floated in the air, flying out.

Looking at the two children playing happily, Su Mo was not idle.

Back and forth, all the stored food materials opened were easily moved to the warehouse by using the storage space.

The extreme wind speed outside also began to slow down.

Standing nearby, Su Mo carefully recorded the attenuation speed of wind speed. After a while, without artificial control, the wind speed completely returned to normal.

Try to continue to call the power of blessing, but unfortunately, it is like talking to the air, there is no response.

"It seems that this is the limit of level 1 blessing! The duration of maximum wind output is only about five minutes, and the decay time is three minutes. I expect that the power of blessing is limited, but as long as this power is not rootless, there will always be a day of decoding."

In front of science, there are traces of any extraordinary power.

Although there are not enough instruments to detect the source of power, sumo can also vaguely feel that this power has gradually faded the mysterious veil.

The reason why it looks frightening is that his release method is different from that of the real object, and human beings can't understand it for the time being.

If you really want to compare it, it's no worse than the current power to connect a big fan!

After calling three or five times and finding that the power of blessing would not recover in a short time, sumo simply put it behind him and began to sort out the rest.

At present, all the circuits in the shelter have been erected, and only some small places are left. At present, due to insufficient dedicated wires, they are still empty.

The dozens of meters of PPR water pipes used to erect water lines can only be temporarily placed, waiting for the design and planning of the water tank construction, and then planning into the design of the shelter.

The 50L freezer was placed on the second floor, and the power input of the shelter was connected to the generator, and the freezer began to cool rapidly.

The 400 ampere hour lithium iron phosphate battery previously purchased has gradually reached the load limit under the consumption of today's shelters.

In addition to the electricity required for daily lighting, a normal 50L freezer only needs about 2 degrees of electricity per day to maintain the temperature, except that the first cooling requires a lot of consumption.

With a storage capacity of 400 ampere hours, one charge a day can just ensure the normal power supply.

"It's still difficult to upgrade or manufacture batteries with larger capacity!"

After looking at the 500 survival points needed for the expansion of lithium iron phosphate battery, Su Mo quickly gave up the idea of upgrading.

At present, not to mention the equipment with large capacity to store electricity, but also the equipment with small capacity to store electricity will not appear in a short time.

This is the limitation of scientific and technological level, and it is also a problem that cannot be solved for hundreds of years after the invention of electric power.

For example, batteries and batteries do not store electricity, but chemical energy. For example, capacitors do not store electricity, but magnetic domain energy generated by capacitive media.

The well-known Three Gorges Dam will also convert electric energy into gravitational potential energy through pumped storage.

"It seems that we can only find a way to wait until the secret place to see if anyone still sells batteries. When they are connected in parallel, it can also temporarily relieve the pressure of electricity!"

Thinking that upgrading all places requires a lot of survival, sumo's head is big, so he can only temporarily record these ideas in the material demand.

On the other side, with generator power supply, the freezer cooling speed is extremely fast.

Su Mo got up, threw in all the fresh meat and fresh fruit he got together, and put all the dried noodles in it. These perishable foods don't need to worry for the time being.

Back in the garage on the first floor, sumo tried to call for blessing power again.

This time, it was not talking to the air at all. After calling for the strongest wind, the local speed increased slightly, and after three or five seconds, it returned to normal again.

"It seems that the power of blessing is indeed an invisible substance that is being maintained. After consumption, it must be slowly restored!"

Unable to afford the electric air change device, sumo has tested the limit of blessing. In order to solve the problem, sumo can only start to study the upgrade method of blessing.

There are two ways to upgrade the lion's wind. One is to upgrade the blessing level from level 1 to level 2.

The other is atavism, from the blessing of ordinary lions to the blessing of lion priests, that is, to improve the quality of blessing.

The former only needs 800 points to upgrade, while the latter needs a full 3100 points!

"The development speed is too fast, and the number of days is too few. My current survival point can't supply such a high-speed upgrade of the shelter."

At this moment, sumo finally understood the meaning of the system that the step is too big and easy to bullshit.

Live on the second floor first? Waiting for survival is enough. Are you trying to get into the lower level?

Call out the core tortoise shell, look at the extraordinary blessing power flowing above, click the upgrade panel, and Su Mo meditates quietly.

Like upgrading ordinary items, upgrading blessings can also add materials. In the upgrade level, you only need to add any object with blessing power.

However, in terms of upgrading quality, it requires divine objects higher than blessing level to achieve.

"What do I have higher quality than lion blessing?"

Thinking about everything in the shelter, looking at the supplies from a large beach on the ground, sumo simply began to try one by one.

Divine objects are certainly not food supplies, nor are they cloth sofas.

Among all things, sumo began to try strange materials captured from the previous core one by one.

A sculpture of a dog headed man from Marshall's core looks promising?

Eh, no response!

A stone like Chengren toy, a little mysterious?

Still no response!

notebook? No response!

Su Mo tried every thing he seized.

In the storage space, take out items one by one. If there is no response, put them aside.

Until there were only three things left in the storage space, sumo felt cold and began to take them one by one.

These three items are: an inconspicuous map, a colorful feather, and the diary of Maeda Jianren!

Put the map in, no response, diary, no response.

Colorful feathers that look so coquettish! Naturally, there is no opposition

"What is this in the sleeping trough?"

The last feather that looked ordinary suddenly scattered colorful light when sumo was locked in the system material bar when he had no hope at all!

It seems that a rainbow flies from the feathers and hangs directly above the garage, which is gorgeous.

At the same time, the solid tortoise shell on the ground, two kinds of light that confirmed the extraordinary power, was almost instantly suppressed by this light and hidden in the cracks of the tortoise shell.

"Isn't it true that Maeda Jianren actually has such a good thing in his hand?"

The lion blessing, which requires 3100 upgrade points to return to its ancestry, turns out to be 0 when the feather is locked in sumo's heart!

And the system also gives an alternative upgrade method.

[wind: the wind of the lion]: belonging to the branch under the blessing of the "wind", it comes from the broken wooden lion people's inheritance and sacrifice of gods, and has excellent upgrading potential.

Upgrade direction 1: improve blessing level, enhance blessing ability, expand blessing range, and need survival (0, lock materials)

Upgrade direction 2: improve the blessing quality, turn to lion sacrifice blessing, slightly improve the blessing attribute, improve the blessing potential, and need survival (0, lock materials)

Upgrade direction 3: sacrifice materials. According to the material properties, randomly upgrade the blessing quality level, change the blessing properties, improve the blessing potential, and need survival (300, lock the material)

"Good guy, what's the origin of this feather? It's so valuable?"

Looking at the upgrade method of the system, Su Mo looked confused and simply spent 1 point of disaster points to identify the feather on his hand. The light of the ******** panel flashed, and the gods were not self obscuring, revealing their true colors.

"Is the name the inverse feather of the rat God?"
