My Doomsday Shelter Unlimited Upgrades

This rancid smell is a bit like the rancid smell of water left in the bottle for too long.

Chen Yang didn't know if this water could be drunk, but even if he could drink it, it would definitely not do any good, and he would not experience the joy of drinking water at all.

This instrument is already powerful enough to distill the extremely polluted waste water into this kind of water. Chen Yang is sure that if he distills the water again, he can obtain completely harmless pure water.

However, if the method of two distillations is used, the time cost is doubled, and this efficiency is not as good as the water production of the well.

Chapter 120 T2 technology, penetration filter!

"If double distillation is necessary, there are only two ways left."

"The first is to use the free coupons to continue upgrading the water purifier. The upgrade direction can only improve the quality of the purified water by a small amount, but it still cannot be done in one step."

"And the second direction is to continue to expand the capacity of the well. The last expansion directly increased the capacity by ten times. If it is increased by ten times this time, then there is no need to worry. 250L of water per day is definitely enough."

"But if we continue to expand the well, we need 3000 survival points..."

After a short thought, Chen Yang decided to try his luck by upgrading the water well first. After all, 3000 survival points are cheaper than 4000, and the amount of expansion is quantum water, which should definitely not be a loss.

Coming to the water well again, Chen Yang took the test very seriously this time. He tried the materials in the backpack one by one, and found that none of the materials in the backpack could reduce the survival points for upgrading.

"The full payment of 3000 survival points can't be paid in installments, it's really fucking expensive!"

After much deliberation, Chen Yang finally decided to grit his teeth and stand up!

Beat a fight, bike change bike!

Take a gamble, the motorcycle becomes a Land Rover!

"Ollie, do it guys!"

[Are you sure to upgrade the water well upgrade direction one? 】

"confirm!"

Chen Yang has also spent a lot of money, but he has never experienced the "big money" at the point of survival.

For the first time, I was a little nervous.

Chen Yang didn't even dare to open his eyes, but when the prompt that the upgrade was completed popped up, he finally chose to face the reality.

【Well Water Extractor】:

Current efficiency: 100000ml per day

"Ten million...one hundred thousand milliliters, that's one hundred liters?"

Chen Yang counted several zeros several times in a row, until he confirmed that it was indeed one hundred liters instead of one thousand liters, a feeling of regret emerged spontaneously.

"Meow! Why is it only quadrupled? You get what you pay for as promised?!"

The first upgrade was a ten-fold expansion, and the second upgrade cost several times more than before, but the expansion multiple was far less than before.

The survival points spent are more irrecoverable than the water that was spilled, and the water that is spilled can still lie on the ground to cool off. There is no such thing as a refund for survival points.

Chen Yang could only find some suitable reasons to comfort his mentality.

"Quantum water is such a precious thing, it's a panacea for physical fitness! 3000 survival points, 75L more per day, no loss!!!"

But having said that, even if the capacity is expanded to 100L, it still has not reached the standard in Chen Yang's heart, and still has not reached the point where he can use water as he likes.

What Chen Yang wants is the feeling that he doesn't feel bad after taking a shower twice a day.

Before the end of the world, nearly half of the households used more than five tons of water a month.

Drinking is definitely not enough to drink five tons, mainly for household water such as toilets, kitchens, and laundry.

In the current shelters, not to mention bathing, but flushing toilets, washing face, brushing teeth, and even washing dishes, Quantum water is used very sparingly, use as little as possible, and use as little as possible.

If all of these are restored to water, that month will be calculated as 5 tons of water, and the production of more than 100 liters of water will be produced at least a day.

And not only that, now he not only needs to meet the normal living water, but also needs to have water to irrigate the ground. After a while, in summer, the weather will enter an extremely hot state, even if he just goes out for a walk, it will be hot. If you are sweating, it would be great to take a bath every day, and the water consumption will increase.

Calculated in this way, 100L a day is still not enough, and 200L a day may not be too much.

Chen Yang took a peek at the survival point needed to continue expanding the capacity of the well, and almost missed it.

"[-] survival points, why not grab it?!"

But after thinking about it carefully, Chen Yang found that [-] survival points are actually not too much. He earned four or five thousand a day yesterday, and he might be able to save more than [-] in a week.

But Chen Yang knows that wealth cannot be earned, it must be earned.

The feeling of saving money to buy a good car is completely different from buying a good car with spare money.

If you want to expand the water well again, it seems that it is too much in a short period of time, and it will take two or three weeks to make a foundation before continuing to upgrade.

"Hey, then there is only one way left to upgrade the water purifier."

Chen Yang sighed, lost his wife and lost his army, the 3000 survival points were gone, and a bigger one would be spent soon.

Returning to the refuge, Chen Yang came to the side of the all-in-one still, did enough ideological work, gritted his teeth, and used 4000 survival point free coupons.

[Are you sure you want to upgrade the 'Automatic Integrated Smart Distiller' and use the 'Upgrade Free Coupon 1'? 】

"Sure!"

【Upgrading in progress, please wait patiently. 】

White light shrouded the all-in-one still. What Chen Yang couldn't figure out was that the white light became smaller and smaller before his eyes.

"Isn't the general water purification equipment the larger the volume, the more complete the functions, and the cleaner the water purification? Why are they shrinking?"

This time, Chen Yang was not afraid of wasting free coupons. The upgrade function of the system is still very reliable, and it will not be upgraded backwards. There must be a reason for the smaller size of the still, which makes Chen Yang look forward to it.

If he really made an industrial water purifier, even if all the walls in his shelter were torn down, he might not be able to put it down, and getting a smaller version would save trouble.

However, Chen Yang never expected that the upgraded water purifier would be so small!

[Record]: The 'Fully Automatic Integrated Smart Distiller' has been upgraded to 'Penetration Filter'.

[Penetration filter (excellent)]:

A filter that separates water molecules from molecules of other substances through ion penetration.

Upgrade Direction 8000: Strengthen the function of ion penetration. After the upgrade, you can choose to infiltrate specified substances, and you need [-] survival points.

Upgrade direction 10000: Change the water purification principle of the filter, greatly increase the water purification speed, and require [-] survival points.
