Doomsday Survival: I can upgrade entries infinitely

Wang Xuan drove a armored heavy truck to the door of a factory.

At the entrance of this factory, there is a sign that says 'Pingdong Town Waterworks'.

Obviously, this waterworks is still within the boundaries of Pingdong Town.

It will definitely provide running water to Pingdong Town.

As soon as Wang Xuan's armored heavy truck arrived at the gate of the waterworks, the abnormal biological detector that he and Liu Ruoruo carried with them gave off a rush of sirens.

The abnormal biological detectors carried by the other girls in the back also sounded the alarm.

According to the screen of the detector, there are many zombies in this waterworks.

"Come to work!"

Wang Xuan smiled.

Now, they have accumulated a lot of combat experience in dealing with zombies and mutated beasts.

Therefore, when they faced zombies, mutated beasts and other abnormal creatures, they were no longer as flustered as they were at the beginning!
Because the gate of this waterworks is open.

Therefore, Wang Xuan directly drove the armored heavy truck into the waterworks.

"Aah~"

"Ho ho~"

"Ow~"

Soon, Wang Xuan and Liu Ruoruo saw a group of zombies rushing towards them with their teeth and claws baring.

Wang Xuan threw out an identification of everything.

He found that most of these zombies were first-level zombies and second-level zombies, and very few were third-level zombies.

The third-level zombies are the fastest, rushing to the front!

The second-level zombie moved a little slower and followed behind!
Level [-] zombies move the slowest, follow behind!

Of course, this is not absolute!

Wang Xuan discovered that there was a third-level zombie at the very back!

Now, in the eyes of Emperor Xuan, these zombies are resources!

Therefore, he unceremoniously manipulated the photon machine gun on the roof of the armored heavy truck, aimed at these zombies, and fired in one shot!
Bai Xiaomeng and others also controlled the armored vehicle and launched a fierce attack on these zombies!
shhhhhh...

I saw beams of light shooting out!

Zombies fell down one after another!

[Congratulations, kill a level-three zombie, reward: three-star fragments x 10! 】

[Congratulations, Bai Xiaomeng killed a second-level zombie, reward: two-star fragments x 10! 】

[Congratulations, Li Jingxiang killed a first-level zombie, reward: 10 star fragment x [-]! 】

【…】

Soon, the group of zombies in front of them were eliminated by the powerful firepower of Wang Xuan and others.

Afterwards, Wang Xuan and others got out of the car.

"Hee hee, with armored vehicles and abnormal biological detectors, it's much easier for us to deal with zombies now!"

Looking at the zombie corpses all over the floor, Bai Xiaomeng said excitedly.

"Xiaomeng, don't be careless!"

"The zombies we are encountering now are not very powerful!"

"If we encounter more powerful zombies, it may not be so easy to deal with!"

Wang Xuan solemnly reminded Bai Xiaomeng.

In case Bai Xiaomeng is too happy and has paralyzed thoughts!

Be prepared for danger!

Don't be too careless at any time!

"Oh!"

"I understand!"

Bai Xiaomeng looked taught.

"Wang Xuan, the area of ​​this water plant is so huge!"

Li Jingxiang looked at the waterworks in front of her, and sighed with emotion!
She had never been to a water plant before, so she didn't know how big the water plant was.

Of course, none of the people present had been to the waterworks.

Everyone doesn't know how big the waterworks should be.

"It seems that the scale is not small!"

"There should be a factory building for drinking water in front!"

Wang Xuan pointed to a factory building not far ahead, and said.

"Drip drip..."

At this moment, Bai Xiaomeng took a few steps forward.

She had just taken a few steps when the abnormal biological detector on her body sounded an alarm.

"There are zombies in here!"

"Everyone be careful!"

"We need to get rid of all the zombies in the factory first!"

Wang Xuan reminded everyone.

Afterwards, he took Liu Ruoruo and the others with a submachine gun in his hand, and followed the direction prompted by the abnormal biological detector, and walked towards the staff dormitory very vigilantly.

"30 meters left!"

"20 meters!"

"10 meters!"

"Wang Xuan, there are several zombies here!"

Bai Xiaomeng pointed to a dormitory and reminded.

shhhhhh...

Wang Xuan and the others greeted several zombies with the photon submachine guns in their hands.

Soon, these zombies were dealt with by them.

Wang Xuan discovered that the zombies in the waterworks were not very powerful, and Liu Ruoruo and others could completely deal with them.

So, he said to Liu Ruoruo: "Ruoruo, you are cleaning up zombies near the staff dormitory, I'll go to the factory to have a look!"

"Ok!"

"You must be careful!"

Liu Ruoruo and others nodded in agreement.

Afterwards, Wang Xuan came to the plant for drinking water alone.

After entering the factory building, he found that there was a set of complicated-looking machines in the factory building!

This set of machines should be 'drinking water treatment equipment'!
He found that there was an entry on the top of this machine.

【Slightly damaged drinking water treatment equipment】

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

[After the upgrade, this entry will be upgraded to an intelligent integrated water purification equipment for ordinary purification]

[This upgrade requires one-star fragments × 10]

[Currently owning one-star fragments: 15710 pieces]

Without thinking too much, Wang Xuan immediately upgraded the entry of this equipment.

[Congratulations, the upgrade was successful]

I saw a cloud of smoke explode!

A set of "mildly damaged drinking water treatment equipment" in front of me has changed its appearance and become a set of "intelligent integrated water purification equipment for ordinary purification".

On this set of equipment, like other items with upgraded entries, a three-dimensional code also appeared.

According to the system's understanding, this set of equipment can also be controlled remotely through the Smart Butler APP on the Quantum smartphone!
At this time, some words appeared on the equipment.

[Intelligent integrated water purification equipment for general purification]

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

[After the upgrade, this entry has been upgraded to an intelligent integrated water purification equipment with super purification]

[This upgrade requires two-star fragments x 1]

【Currently own two-star fragments: 11951】

According to the prompts of the system, after another upgrade, the purification ability of this set of intelligent integrated water purification equipment can be greatly improved.

Even if the water source of the river outside is seriously polluted, after being purified by this equipment, it can be purified into extremely high standard drinking water!

The purification effect is a hundred times higher than that of normal water purification equipment!
Even if you drink it directly, there is no need to boil it, there is no problem!

Super safe!

After upgrading the water purification equipment, Wang Xuan left the workshop and walked towards the entrance of the water plant.

"Wang Xuan, where are you going?"

Liu Ruoruo saw Wang Xuan and hurriedly asked.

"Go to the door!"

Wang Xuan said without looking back.

"What are you doing at the door?"

Liu Ruoruo and the others were puzzled for a while.

And Wang Xuan didn't explain, but went straight to the gate of the waterworks...
