Doomsday Survival: I can upgrade entries infinitely

Wang Xuan and the other three discovered a basement in a family's house.

After entering the basement, the three of them searched separately to see if there were any important supplies that could be used.

Wang Xuan unexpectedly found three pistols in a box.

Moreover, some words appeared on the three pistols.

【Simple homemade pistol】

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

[After the upgrade, this entry has been upgraded to a highly lethal zombie photon gun]

[This upgrade requires one-star fragments × 10]

[Currently owning one-star fragments: 1425 pieces]

"A zombie photon gun with great lethality?!"

"I go!"

"This is possible!"

After Wang Xuan saw these text reminders, he was overjoyed.

Although, he and Liu Ruoruo can now blow the heads of the first-level zombies with one stick, and they can also deal with the second-level zombies.

However, if they have a pistol that can kill zombies, then their ability to protect themselves is even stronger!
According to the prompt of the system, the zombie photon gun with great lethality can kill zombies and mutant beasts.

However, it does no harm to humans!

This is very good!
At least you won't hurt your own people by mistake!

Wang Xuan upgraded the pistol without hesitation.

[Congratulations, the upgrade was successful]

I saw a cloud of smoke explode!

A pistol in his hand turned into a cool zombie photon gun.

At this time, some words appeared on the zombie photon gun.

【Very lethal zombie photon gun】

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

[After the upgrade, the entry has been upgraded to a powerful all-round photon gun]

[This upgrade requires two-star fragments x 1]

【Currently own two-star fragments: 13】

According to the prompt of the system, the extremely lethal almighty photon gun can not only kill zombies and mutant beasts, but also kill humans.

Although the risk factor of the Almighty Photon Gun is relatively high.

However, this gun is also useful.

Now they are basically facing zombies and mutated beasts.

However, there should be many survivors in this world.

These survivors may have lost their basic humanity in order to survive.

These survivors may have violent conflicts with them as they compete for vital material resources.

These survivors may also covet the beauty of Liu Ruoruo, Gao Yanan and other girls, and want to do evil things to them.

So, they must have a weapon that can be used against other people.

Therefore, Wang Xuan immediately upgraded the entry of this pistol.

[Congratulations, the upgrade was successful]

I saw a cloud of smoke explode!

The zombie photon gun in Wang Xuan's hand turned into an omnipotent photon gun with a different shape.

Afterwards, he immediately put away the almighty photon gun alone.

Then, he upgraded the other two pistols.

However, he just upgraded the other two pistols into a very lethal zombie photon gun.

Zombie photon guns can only kill zombies and mutant beasts, but cannot harm humans.

He intends to give these two zombie photon guns to other girls.

However, he didn't know the character of the other girls.

In case there are people with bad intentions!
Then, handing the Almighty Photon Gun into the hands of such a person will bring safety hazards to other people.

Only after he understands the character of the other girls and is sure that there are no bad-hearted people, will he upgrade the zombie photon gun to an all-powerful photon gun, and then hand it over to them.

In addition, according to the system's prompt, he will get a corresponding reward every time he kills a zombie or mutant beast with his upgraded pistol.

That is to say, no matter who he gave the upgraded pistol to, as long as whoever uses this gun to kill zombies or mutant beasts, he can get corresponding rewards!
In this way, he has another source of rewards.

This made him ecstatic!
After upgrading the other two pistols, Wang Xuan put the other two pistols into his trouser pockets.

Afterwards, Wang Xuan turned around and found that Gao Yanan and Zhao Yuting had found some supplies such as toilet paper.

Then, they took the supplies and left the basement.

Next, they went to another family to collect supplies.

After 'searching' the family's important supplies, it was getting dark.

Moreover, the tricycle is already loaded with stuff.

So, they decided to call it a day!
Afterwards, Wang Xuan pedaled the tricycle, Gao Yanan and Zhao Yuting sat on the edge of the tricycle, and the three returned home happily.

"A lot of supplies have been harvested this time!"

"These supplies are enough for us to survive for a while!"

Gao Yanan looked at the 'trophy' in the tricycle, smiled slightly and said.

"Wang Xuan, should we go to other people's houses to collect supplies tomorrow?"

Zhao Yuting asked.

"Of course I have to collect it!"

"I estimate that the production system in this world has completely collapsed!"

"In other words, I'm afraid there are no new products produced!"

"No new food is grown!"

"Therefore, all kinds of living materials become the necessary conditions for us to survive in this world!"

"Although this world is already full of zombies!"

"However, I estimate that there should be many survivors in this world!"

"In order to prevent the living supplies in the village from being preempted by other survivors, we must collect all the living supplies in the village as soon as possible!"

"Only in this way can we ensure that we can tide over the current difficulties!"

Wang Xuan explained.

In this doomsday world where zombies are rampant and mutant beasts are everywhere, the living conditions they face are very cruel.

Since they are from the same world, they are a community of destiny.

They must first ensure their survival in this world.

As for the other survivors in this world, for them, they are like enemies for the time being.

Therefore, they collected as many living materials as possible.

"Ok!"

"Wang Xuan, what you said is very reasonable!"

Both Gao Yanan and Zhao Yuting nodded in agreement with Wang Xuan's point of view.

At this moment, Gao Yanan suddenly looked to the east: "What's the sound?"

All I could hear was a rushing sound from the east.

"It sounds like some animal running!"

Wang Xuan immediately became alert.

He jumped off the tricycle and took out an almighty photon gun from his trouser pocket.

At this time, he saw a huge black bull running towards them.

"This big black bull may have mutated!"

"Hurry up and hide aside!"

Wang Xuan reminded Gao Yanan and Zhao Yuting loudly.

At the same time, he had already raised the almighty photon gun in his hand and aimed the gun at the black bull that was running wildly.

Though he's never used a pistol before.

However, he has seen some characters use pistols in film and television dramas.

Therefore, he imitated the characters in the film and television drama, holding the almighty photon gun in his hand.

According to the prompt of the system, the Almighty Photon Gun also comes with an optical sight.

He quickly opened the optical sight, and a beam of red light shot out.

"Wang Xuan, be careful!"

Gao Yanan and Zhao Yuting, who were hiding aside, saw that there was actually a pistol in Wang Xuan's hand.

They were all very surprised.

However, at this moment, they were even more worried about Wang Xuan.

Because that berserk big black bull was about to charge up to Emperor Xuan.

If Wang Xuan didn't dodge again, Wang Xuan would be trampled to a pulp by this big black bull.

If something happened to Wang Xuan, the group of girls would really not know how to survive in this zombie-infested doomsday world.

Besides, Wang Xuan was their savior.

They didn't want anything to happen to Wang Xuan even more!

At this moment, Wang Xuan's heart was also tense!
It was his first time to use the Almighty Photon Gun, and he was still somewhat unfamiliar with it.

He tried hard to use the optical sight to aim at the head of the raging big black bull in front of him.

I saw a red dot flashing back and forth on the head of the big black bull!

After seeing the right moment, Wang Xuan immediately pulled the trigger!

call out!
A sharp whistle!

A white beam of light shot out from the muzzle of the gun and shot at the head of the big black bull.

At the same time, Wang Xuan immediately dodged aside with lightning speed.

Only a scream from the big black cow was heard.

Since Wang Xuan dodged in time, the big black bull didn't bump into Wang Xuan.

However, Wang Xuan was surprised to find that the big black bull just kept screaming, but did not fall down.

After the big black bull rushed forward for a certain distance in inertia, he quickly turned his body around and rushed towards Wang Xuan again frantically.

The big black cow at this moment is much crazier than before!
A blood hole appeared on the neck of the big black bull, and blood kept gushing out.

"I go!"

"Just missed!"

Wang Xuan didn't expect that he missed the shot.

I clearly aimed at the head of the big black bull just now, why did I miss it?

In fact, this is not surprising!
After all, the big black bull has been running wildly.

Even if Wang Xuan aimed right one moment, the next moment he might miss it because of the big black bull running wildly.

The fundamental reason for this was that Wang Xuan had never learned marksmanship before, and his marksmanship was very good. Even with an optical sight, it was still difficult to hit the head of the big black bull.

However, Wang Xuan did not give up!

He continued to hold the Almighty Photon Gun tightly in his hand, used the sight to aim at the big black bull's head, and then decisively pulled the trigger!
Scream!
A beam of light shot out!

It hit one of the big black bull's horns!

Missed again!

It's ok!
Come again!

Wang Xuan's current physique is much higher than normal people.

Therefore, the agility and speed of his body are also much higher than normal people.

Therefore, there was no way for the big black bull to charge into Wang Xuan's body.

Every time Wang Xuan fired a shot, he quickly dodged aside.

So repeated several times!
He finally shot the big black bull in the head.

"Moo..."

There was a shrill scream from the mouth of the big black cow.

Immediately afterwards, there was a muffled bang!
The big black bull fell to the ground with a bang, kicking up a cloud of dust.

[Congratulations, you killed a second-order mutant beast, reward: two-star fragments x 20, skill 'Sharp Spear'! 】

"I go!"

"This mutant beast is actually a second-order mutant beast!"

"No wonder it's so powerful!"

Wang Xuan was surprised in his heart.

However, he was more of a surprise!

Because he not only got 20 two-star fragments this time.

Moreover, he also acquired a skill 'Sharp Spear'!
The rewards this time are quite rich!
According to the system's prompt, to learn the 'Sharp Spear Technique', you need to consume 10 one-star fragments.

So, he immediately consumed 10 one-star fragments and learned the 'Sharp Spear Technique'!
[Congratulations, you have successfully learned the skill 'Sharp Spearmanship', and you have just gotten a glimpse of it! 】

Immediately, a lot of information about spear techniques flooded into Wang Xuan's mind.

Next, he consumed another two-star fragment to increase the level of the 'Sharp Spear'.

[Congratulations, you have successfully upgraded the skill 'Sharp Spearmanship', and you have entered the room! 】

At this moment, the skill column of the system panel becomes like this:

[Skills: Shennong Medicine (Entering the Hall), Spearmanship (Entering the Hall)]

Today, Wang Xuan already has two skills.

They are 'Shen Nong Medicine' and 'Sharp Spear'!
Moreover, they have all reached the level of entering the hall.

"Wang Xuan, are you alright!"

"It's just so dangerous!"

Gao Yanan and Zhao Yuting saw Wang Xuan killed the ferocious big black bull, and immediately ran to Wang Xuan.

"I'm fine!"

Wang Xuan put away the Almighty Photon Gun.

"Wang Xuan, where did you get the gun you shot the big black bull?"

Gao Yanan and Zhao Yuting looked at Wang Xuan very puzzled.

"Let's go back first!"

Wang Xuan has not yet figured out how to explain the source of the Almighty Photon Gun.

So, he decided to drag on first.

Seeing that Wang Xuan refused to speak, Gao Yanan and Zhao Yuting had no choice but to give up.

Afterwards, Wang Xuan pedaled the tricycle, took Gao Yanan and Zhao Yuting, and headed towards the villa.

Soon, they returned to the villa.

They entered the yard and saw that a fire had already been built in the yard, and there was a simple shelf on top of the fire with a wok on it.

Ye Keqing was holding a spatula in her hand and was bending over to cook.

"You are back!"

Ye Keqing saw Wang Xuan and the other three came back, and quickly stood up.

The others also quickly looked at Wang Xuan and the other three.

"Ms. Ye, are you cooking?"

Wang Xuan asked.

"Yes!"

"There's no electricity here, and no natural gas!"

"And everyone wants to eat fried vegetables!"

"So, we built a fire and built a simple shelf to cook!"

Ye Keqing explained helplessly.

"Uh……"

"This problem of cooking is indeed a big problem!"

"There is also a problem with electricity!"

Wang Xuan pondered, thinking about how to solve these problems.

"More than these questions!"

"There are many more!"

"For example, the problem of taking a bath, and the problem of going to the toilet!"

Ye Keqing said.

Then, other girls also raised various life problems.

Indeed, they have now arrived in a world of scarce resources.

Everything is missing here!
Water shortage!

Power out!

Lack of gas!

……

All of a sudden lack of so many living resources!
Of course, everyone is a little uncomfortable for a while!

At this moment, Wang Xuan seemed to think of something.

He said, "I'll go to the underground garage of the villa, you guys wait for me here first!"
