Doomsday Survival: I can upgrade entries infinitely

Wang Xuan drove the electric tricycle by himself and arrived in front of the water tower.

He looked around and after making sure that there was no one around, he began to upgrade the entry of this water tower.

[very simple water tower]

[This entry has met the upgrade conditions and can be upgraded]

[After the upgrade, this entry will be upgraded to a smart water tower with automatic purification]

[This upgrade requires one-star fragments × 10]

[Currently owning one-star fragments: 1325 pieces]

Wang Xuan upgraded the entry of this water tower without hesitation.

[Congratulations, the upgrade was successful]

I saw a cloud of smoke explode!

The very simple water tower in front of me has changed its appearance and turned into a smart water tower with automatic purification.

At this time, Wang Xuan was surprised to find that the strange pattern similar to the QR code appeared on the smart water tower again.

He has seen this similar pattern many times.

The variable energy switch is on!

On board the bioenergy generator!
On the eco-friendly toilet!

There have been such strange patterns!
He was very curious, what is the function of this strange pattern?
Unfortunately, the system has not given a prompt.

never mind!

Someday he'll figure it out!
Later, he learned about this smart water tower through the system.

This smart water tower is very smart and can automatically pump water up from the pond according to the water storage in the water tower.

Moreover, this smart water tower can also purify water automatically!

The purified water not only filters out all impurities, but also fully disinfects it.

Therefore, the water coming out of the water tower fully meets the standard for direct drinking.

Of course, Wang Xuan and the others already had a well with a clear fragrance and sweet water.

The water in this well has not only been super-purified, but after drinking, it can slightly improve everyone's physique.

Therefore, they usually drink water from wells.

As for the water in the water tower, it can be used for bathing, washing clothes, vegetables or other things.

After Emperor Xuan finished upgrading the entry of this water tower, some words appeared on this water tower.

[Smart water tower with automatic purification]

[This entry has met the upgrade conditions and can be upgraded]

[After the upgrade, this entry will be upgraded to a smart water tower with automatic purification and super defense]

[This upgrade requires two-star fragments x 1]

【Currently own two-star fragments: 35】

"Smart water tower with super defense?"

"This is possible!"

Wang Xuan was overjoyed.

In this world, there are very ferocious mutant beasts.

In case that mutated ferocious beast is not happy, just got on this smart water tower, and wants to hit this smart water tower, it will be in big trouble.

Therefore, with the entry of super defense, this smart water tower can withstand the attack of powerful mutant beasts.

Of course, if any enemy wants to destroy this water tower, it may not be easy!

Moreover, this smart water tower can be fully disinfected and automatically purified!
Even if someone poisons the pond, it will not affect the safety of the water.

Therefore, with this smart water tower, they don't have to worry about running water in the future.

Wang Xuan immediately consumed a two-star shard to upgrade the water tower again.

[Congratulations, the upgrade was successful]

At this moment, this smart water tower with automatic purification has been upgraded to a smart water tower with automatic purification and super defense.

According to the introduction of the system, this smart water tower needs to install the No. [-] energy bar to provide power support.

Today, the smart water tower comes with a No. [-] energy bar.

So, this smart water tower is ready to use.

From now on, Wang Xuan only needs to wait until the No. [-] energy bar of the smart water tower is about to run out, and then install a brand new No. [-] energy bar on the smart water tower.

But there is a small problem!

How did he know that the energy bar used by the smart water tower has been consumed a lot.

If there is a way to check the remaining energy of the energy bar in the smart water tower in real time, then the water tower will be more intelligent.

"However, it is useless to think about this question now!"

"I don't know if this water tower can provide running water to the villa?"

"I don't know if there is water in the villa now?"

"Let's go back quickly and have a look!"

Thinking of this, Wang Xuan sat on the driver's seat of the electric tricycle, then drove the electric tricycle, and hurried back to the villa impatiently.

……

In the villa.

Ye Keqing and the others were waiting with great anticipation for news from Wang Xuan.

"I wonder if Emperor Xuan can repair the water tower?"

"It would be great if Wang Xuan could repair the water tower, and we won't have to fetch water to take a bath all the time in the future!"

"Yeah, fetching water to take a bath every day is really too troublesome!"

"..."

A group of girls were very much looking forward to Wang Xuan's ability to repair the water tower.

Because fetching water to take a bath every day is really a very troublesome thing.

However, they were worried that Wang Xuanxiu was not good!
After all, building a water tower is a relatively professional matter.

Wang Xuan was just like everyone else, he was just a student, how could he know how to build a water tower!
and also!

Even if Emperor Xuan built the water tower, there is no way to guarantee that the running water in this villa comes from the water tower!
"I'll go to the kitchen to see if the tap water is coming!"

Bai Xiaomeng said eagerly.

She has been to the kitchen many times, but every time she is very disappointed.

"Xiaomeng, you have gone to the kitchen to drain water 800 times!"

"Wang Xuan just went to the water tower not long ago, how could the water tower be repaired so quickly!"

Said a girl.

"It's not as exaggerated as 800 times!"

"At most a dozen times!"

Bai Xiaomeng rolled her eyes.

However, she ignored the girl's words, but stubbornly came to the kitchen and turned on the faucet.

wow...

I saw white water coming out of the faucet!
"The water is out!"

"The water is out!"

"It's really out of water!"

"Come and take a look!"

Bai Xiaomeng exclaimed in great surprise.

"what?"

"Is it really out of water?"

When Ye Keqing and the others heard Bai Xiaomeng's shout, they were stunned for a moment, and then they were ecstatic.

They poured into the kitchen one after another!
Sure enough, they saw the faucet in the pool, and it was spraying water!
"It's really out of water!"

"It's really good!"

"We will have running water in the future!"

"Tonight, we can finally take a good shower!"

"I don't need to wash my clothes by hand in the future!"

"Wang Xuan is really amazing, he actually repaired the water tower!"

"Wang Xuan is really handsome!"

"Everyone, don't rob me, Wang Xuan is my husband!"

"Don't be smug, will Emperor Xuan take a fancy to you?"

"..."

A group of girls saw that the water was coming out of the faucet, and they were all very excited.

At this moment, Wang Xuan is not here.

Therefore, a group of girls gathered together and dared to say anything.

Why did Wang Xuan be their husband!

They want to marry Wang Xuan!
Wait a minute!

If Wang Xuan was here, I'm afraid they would be embarrassed to say such a thing.

At this moment, someone shouted in the yard: "Wang Xuan is back!"

Afterwards, the girls gathered in the kitchen all ran out of the kitchen very excitedly, as if they were welcoming a hero, and greeted Wang Xuan's return.

"Wang Xuan, you are back!"

"Wang Xuan, you are so powerful that you actually repaired the water tower!"

"We now have running water!"

"Wang Xuan, you are simply our savior!"

"..."

Just as Wang Xuan got off the electric tricycle, he was surrounded by a group of Yingying and Yanyan.

They all praised Wang Xuan for being amazing!

"Is it really water?"

"Great!"

"I gonna go see!"

After Wang Xuan heard what these girls said, a surprised smile appeared on his face.

The smart water tower really works!

Immediately he went into the kitchen and turned on a tap.

Immediately!

A jet of clean and clear water rushes out of the faucet!

"Sure enough, water came out!"

"awesome!"

"By the way, have you checked to see if the water heater works?"

Wang Xuan asked.

"You came back before we had time to look!"

"Let's go to the bathroom together!"

Ye Keqing said with a smile.

"Ok!"

Wang Xuan nodded.

Afterwards, he walked ahead and led a group of girls to the bathroom on the first floor.

He came to the bathroom of the bathroom and turned on the shower faucet.

Immediately, water spouted from the shower head!

"Great!"

"The water heater is working!"

"We won't have to fetch water to take a bath in the future!"

"We can have a clean shower tonight!"

"..."

When a group of girls saw water sprayed from the shower head, they all cheered and cheered excitedly.

After a while, Wang Xuan tried the water temperature.

hot!

There is nothing wrong with the water heater!
"Finally solved the big problem of bathing!"

Wang Xuan sighed with emotion.

"I wonder if the water heater on the second floor can be used?"

Zhao Yuting said.

After all, there were 37 of them.

If there is only one place to take a bath, I'm afraid to line up to take a bath, which is very time-consuming.

Especially except for Wang Xuan, everyone else is a girl.

Girls take a bath, generally more time-consuming.

So, if the bathroom on the second floor can also take a shower.

Then, it can greatly save the time of queuing up to take a bath.

"I'll go to the bathroom on the second floor!"

A girl couldn't wait to run to the bathroom on the second floor.

Soon, the girl ran down from the second floor and said excitedly, "The bathroom on the second floor can also be used!"

As soon as this remark came out, everyone cheered!
[Favourability from Ye Keqing +5! 】

[Gao Yanan's favorability +5! 】

[From Zhao Yuting's favorability +5! 】

【…】

Because Wang Xuan solved the problem of tap water for everyone, he once again won everyone's favor.

Their favorability towards Emperor Xuan increased a bit.

After solving the tap water problem, Wang Xuan took Gao Yanan and Zhao Yuting to continue to collect supplies from other houses in the village.

In the process of collecting supplies, they encountered some zombies and mutant beasts.

However, these zombies and mutant beasts are not very powerful.

Wang Xuan dealt with these zombies and mutant beasts very easily.

In the evening, they stopped collecting supplies.

The village is not very big.

Therefore, Wang Xuan and the other three had already collected most of the other people's supplies.

Only a small number of people are left!

It only takes about one day for them to collect all the important supplies in the village to the villa where they are temporarily staying.

After dinner, everyone began to take a bath one after another.

Now with running water, you can use the water heater in the bathroom to take a shower.

Therefore, everyone is in a relatively good mood.

Because the weather is hotter now!

Therefore, after everyone took a bath, they gathered in the living room in twos and threes to chat.

Fortunately, there is an air conditioner in the living room, which is very cool!

Even though there was Wang Xuan, the only boy in the living room!

However, after a long time, everyone got used to it, and they were no longer as awkward as they were at the beginning!

So everyone dresses cooler!
It is simply a beautiful landscape!
In fact, like other girls, Wang Xuan was not used to it at first.

At first, he was surrounded by Yingying and Yanyan, and he felt awkward as he was the only boy.

But after a long time, he also let go!
Is he still worried that these women will eat him up?
"Ugh!"

"Although we already have electricity now!"

"However, there is no Internet here, and now our mobile phones are no different from bricks!"

Bai Xiaomeng fiddled with the mobile phone in her hand very boredly, and said boredly.

"Even if there is a network, you can use it!"

"The mobile phone charger interface here is completely different from our mobile phone charger interface!"

"There is no way to charge it at all!"

Zhao Yuting said helplessly.

"If there is a network, we can go to other places and get some mobile phones!"

Bai Xiaomeng rolled his eyes and said.

"Right!"

Zhao Yuting nodded.

"Xiaomeng, stop wishful thinking!"

"This world is full of zombies and mutant beasts!"

"It's good to be alive!"

"Still want to go online?"

"Go dream!"

Liu Ruoruo sighed and said.

"Even if you can't surf the Internet, it would be great if you can make phone calls!"

"If you can make a phone call, it will be very convenient for everyone to communicate with each other!"

Bai Xiaomeng thought for a while and said.

"Yes!"

"It would be much more convenient if I could make a phone call!"

"It's a pity that zombies and mutant beasts are rampant in this world, and those telecom operators no longer exist!"

"All communication has been interrupted!"

"So, there is no way to call at all!"

Liu Ruoruo sighed.

"Ugh!"

"Can't go online again!"

"Can't call again!"

"This phone has really turned into a brick!"

"The days to come will be really difficult!"

Bai Xiaomeng also sighed.

"I don't know what will happen to us in the future?"

"Do you want to stay in this villa all the time?"

Zhao Yuting said.

"Wang Xuan, what are your plans?"

Liu Ruoruo looked at Wang Xuan and asked.

The other girls also looked at Wang Xuan one after another.

"Let's go one step at a time!"

"We can only say that we are barely gaining a foothold in this world!"

"What kind of situation we will encounter in the future is still unclear!"

"So, I can't give a definite answer!"

Wang Xuan said helplessly.

At this moment, he suddenly found some texts appeared on his mobile phone.

[Some outdated smartphones]

[This entry has met the upgrade conditions and can be upgraded]

I go!

His smartphone also has entries?
Can also be upgraded?

I don't know what kind of mobile phone his smartphone will become after the upgrade?
