My Doomsday Shelter Unlimited Upgrades

"Dangtang Performance Center, what are you using this thing for????"

Chen Yang's head was full of question marks, 700W of electricity is not enough for one kilowatt-hour, shake the power for one hour, use the electricity for 5 minutes, light on the light for a while, and one kilowatt-hour of power will be gone.

Even if it's to save money, it's not like this!

Just stepping on a foot shower when taking a bath is tiring enough, and adding a rocking power generation device will net calories consumed on it.

Fortunately, he has a system to upgrade the generator.

Putting away the hand generator, Chen Yang continued to carry out carpet-like excavation nearby.

Mixing console, dressing table, lighting table... He dismantled everything up to the control room, and he didn't find any sign of the second generator.

In the performance center of such a big university, the generator was operated by hand, and Chen Yang was 1 speechless in his heart.

After searching this area, he will almost use up his time in the morning. It is a good thing to gain something. Before leaving, Chen Yang digs a certain distance forward, wanting to see the appearance of the abyss just now with his own eyes.

A passage was dug, and Chen Yang carefully disassembled the last bit of ruins in front of him, and the bottomless abyss appeared in front of him.

Chen Yang quickly backed up a little. He didn't have a fear of heights, but in such a situation, who wouldn't be afraid to accidentally step on the ground and fall?

Observing the crack from his point of view now is even more frightening than seeing it from the sheriff's point of view. It was pitch black under the crack. He threw some large stones down and waited for a long time without any response.

"What magnitude must this earthquake be, eight? No, I think it must be at least magnitude ten."

In the face of natural disasters, human beings are so small, Chen Yang has the latest understanding of the concept of the end of the world.

Such cracks, placed in no-man's land, are called the uncanny workmanship of nature, and appear in cities, which is the end of natural disasters.

While feeling emotional, Chen Yang had a new idea.

Chapter 21 Sewage Discharge Problem Solving

Since such cracks are bottomless, can he connect the shelter's sewage system to this side?

Judging from the current situation, there is still a long way to go before he can design a complete set of water purification equipment.

Even if he gets a set of water purification equipment, he doesn't want to drink the purified sewage.

Thinking about what the predecessor of water was, he felt a little conflicted.

As for collecting sewage to form a biogas digester, using the biogas to generate electricity or use it as a fertilizer, he had considered the idea, but he eventually abandoned it.

Firstly, he does not understand the specific principles of biogas digester construction, and secondly, he does not have so much sewage to generate biogas.

In rural areas, biogas digesters are connected to livestock pens, toilets, and solar greenhouses, and human and livestock feces continuously enter the biogas digesters to ensure the normal and continuous gas production of the biogas digesters.

He is alone now, even if everything he eats is excreted, how much methane can he produce?

Forget it.

To save another trip, Chen Yang directly used the construction function in the system to set up a sewage pipeline on the edge of the cliff.

The pipeline should be kept at a certain degree of inclination, so that the sewage can be left smoothly without clogging.

At the same time, the diameter of the pipe must be large, so that not only sewage can be discharged, but even garbage can be thrown directly from the pipe.

There are many materials used for such pipes, mainly plastic.

Chen Yang mixed materials with survival points, and laid pipes all the way around the shelter. The plastic collected in the past few days was used up, and 45 survival points were used up.

Survival point balance: 333

"Hey, the numbers are auspicious."

After being busy until around four o'clock in the afternoon, Chen Yang finally connected the pipeline under the ground of the shelter.

According to his idea, he will temporarily design two sewage outlets in the shelter.

One is the bathroom and the other is the kitchen.

The two sewage outlets are confluent through the ground, transported together into the large sewage pipe, and discharged into the cracks.

A sewage pipe was led out from the bathroom and the kitchen, and Chen Yang rewarded himself with a sip of quantum water contentedly.

The Quantum Water flavor this time is wine.

Without trying, Chen Yang knew that this pipeline would definitely work, because the system popped up a prompt.

[Simple sewage pipe]:

It can discharge sewage or garbage, and has certain practicability.

Upgrade Direction 20: Increase the radius of the sewage pipe, change the inclination of the sewage pipe, increase the flow of the pipe, and make it less likely to be blocked. [-] survival points are required.

Upgrade Direction 100: Change the material of the sewage pipes to greatly enhance the corrosion resistance and durability of the sewage pipes. [-] survival points are required.

System comment: When you discharge sewage into the abyss, the abyss is also staring at you!

He can perform real-time upgrades in both upgrade directions, but the survival point is to do more important things first.

Today may be Chen Yang's happiest day in recent days, not only because he no longer needs to go to the field to go to the toilet, but more importantly, he is very likely to return to the electrical age today.

I couldn't wait to take out the generator from the system. This hand generator was severely damaged, various parts were scattered all over the place, and the appearance was smashed by reinforced concrete.

After refurbishment with 20 Survival Points, the workbench also unlocks options for generating equipment.

Diesel generators, hydroelectric generators, wind generators...the production formulas of various power generation devices are dazzling.

Generators that can provide power for daily life are relatively high-end equipment. If you use survival points alone to exchange motors, the general price ranges from several hundred to several thousand survival points, and the materials you need are also hundreds of dollars.

After these few days of observation, Chen Yang has summed up some basic laws of system functions.

One of the important points is that crafting items is far less cost-effective than upgrading items.

For example, the hand generator he owns now, the upgrade of the hand generator only needs 70 survival points to upgrade to the next level.

Although I don't know what the next level of generator is, but among the production functions of the workbench, the generator with the lowest model needs to have 100 survival points, and it is also hand-cranked.

Obtaining the functions of the system does not mean that you can live comfortably. If you want to improve your life quickly, you must learn to manage money.

Never make things that can be upgraded, this is Chen Yang's latest creed of the end of the world.

The power of the hand generator was too low, and it was troublesome to use, so Chen Yang upgraded it without even thinking about it.

Put some alloy steel on the upgrade option, and the 70 survival points required for the upgrade have been reduced to 40.

"Generator, upgrade!"
