Doomsday Survival: I can upgrade entries infinitely

【Temperature gun for detecting human body temperature】

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

[After the upgrade, this entry has been upgraded to an abnormal biological detector that can detect abnormal creatures such as zombies and mutated beasts within 10 meters]

[This upgrade requires one-star fragments × 10]

[Currently owning one-star fragments: 8970 pieces]

"Abnormal biological detector?!"

"This instrument is powerful!"

"I didn't expect that the temperature measuring gun could be upgraded to an abnormal biological detector!"

"This entry is too strong!"

Wang Xuan looked at the entry on the temperature measuring gun, and was very pleasantly surprised.

This abnormal biological detector is really useful!

With this detection instrument, it is possible to detect whether there are any abnormal creatures such as zombies and mutant beasts nearby.

In this way, there is no need to worry about zombies and other abnormal creatures hidden nearby.

Moreover, there are quite a few temperature measuring guns in this small manual workshop.

This entry appeared on these temperature measuring guns.

In other words, after the entries of these temperature measuring guns are upgraded, they can all become abnormal biological detectors.

With so many abnormal biological detectors, Liu Ruoruo and others can use this instrument to search for abnormal creatures such as zombies and eliminate all potential safety hazards.

In the future, they don't have to worry about a zombie or other abnormal creature suddenly appearing somewhere.

Moreover, this abnormal biological detector also has the function of automatic alarm.

Once there are abnormal creatures such as zombies approaching the detectable range of the instrument, the instrument will automatically alarm.

This greatly improves their own safety.

Therefore, this entry must be upgraded.

Wang Xuan immediately upgraded all the temperature measuring guns here.

At this moment, these temperature measuring guns have become abnormal biological detectors.

At this time, these abnormal biological detectors had entries again.

[An abnormal biological detector that can detect abnormal creatures such as zombies and mutant beasts within 10 meters]

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

[After the upgrade, this entry has been upgraded to an abnormal biological detector that can detect abnormal creatures such as zombies and mutated beasts within 100 meters]

[This upgrade requires two-star fragments x 1]

【Currently own two-star fragments: 5617】

This entry has not changed much.

The main change is that the detectable range has become larger.

Previously, the detectable range was within 10 meters.

After the upgrade, the detectable range is expanded to within 100 meters.

In this way, the safety is further improved!
As long as any abnormal creatures such as zombies and mutated beasts enter the range of 100 meters of the instrument, the instrument will automatically alarm.

This increases everyone's response time!

Security has been greatly improved.

Therefore, this entry must also be upgraded.

Therefore, Wang Xuan once again upgraded the entries of all abnormal biological detectors.

He counted, a total of 49 abnormal biological detectors!

Enough for one of them.

Moreover, this detector is very small, about the size of a pistol.

The shape is also similar to a pistol!
Of course, the shape is almost exactly the same as the temperature gun.

Not much has changed.

On top of the instrument, there is also a display screen.

The screen will show whether there are any abnormal creatures such as zombies and mutant beasts nearby.

If there is, it will also display the number, orientation, distance and other information of abnormal creatures such as zombies and mutant beasts!
Very powerful!
Wang Xuan found a very strong packing box, and put 37 abnormal biological detectors in it.

He put the remaining abnormal biological detectors in his storage ring.

Of course, he didn't let go of other things in this house.

As long as he thinks useful things, he puts them all in his storage ring, just in case!

After finishing, he took out a smart shackle from the storage ring and put it on Chen Jianhao's right ankle.

Then, he woke up Chen Jianhao!

"Uh……"

"What happened to me just now?"

Chen Jianhao got up from the ground, only feeling dizzy for a while.

However, he quickly recalled the previous events.

Before, he wanted to take out his hidden weapons from the place where he hid them.

Suddenly, he was hit on the back of the head.

At that time, only he and Wang Xuan were present.

Obviously, it was Wang Xuan who hit him on the back of the head.

"Look at your right ankle!"

Wang Xuan pointed to Chen Jianhao's right ankle.

Chen Jianhao immediately looked down at his right ankle!
He found that on his right ankle, he was wearing a weird gadget at some point: "What is this?"

"It's shackles!"

"It can be automatically discharged!"

"In the future, if you dare to have any unruly thoughts, this shackle will punish you and automatically discharge you!"

"Don't even try to violently destroy this shackle!"

"Because when you destroy violently, this shackle will also automatically discharge!"

Wang Xuan warned Chen Jianhao.

Before, he passed the identification technique, and identified this Chen Jianhao as sinister and cunning, which was somewhat unreliable.

That's why he put shackles on this Chen Jianhao.

In order to prevent Chen Jianhao from playing tricks secretly!
Of course, he could also directly kill Chen Jianhao.

However, Chen Jianhao still has value.

At least there are people like Chen Jianhao who can supervise certain people!

Besides, Chen Jianhao is also a labor force!

It can also generate value!
When Chen Jianhao heard what Wang Xuan said, he obviously didn't believe that this little thing could discharge electricity.

"how?"

"You do not believe?"

Wang Xuan saw that Chen Jianhao didn't believe it.

"no no!"

"How could I not believe it!"

Chen Jianhao shook his head again and again.

At this moment, he has already fallen into the hands of Wang Xuan, so of course he dare not deny Wang Xuan.

However, although he said he believed it, he still didn't believe it in his heart.

"I see you still don't believe it!"

"Well!"

"I'll let you experience the function of this shackle!"

Wang Xuan saw that Chen Jianhao still didn't believe it.

So, he immediately picked up a brick in the yard and smashed the smart shackle on Chen Jianhao's right ankle.

Immediately, the smart shackles were automatically discharged.

Chen Jianhao was so shocked that he didn't even recognize his mother!
"How about it?"

"Believe it now!"

Wang Xuan looked at Chen Jianhao and smiled slightly.

"I believe it!"

"I believe it!"

At this moment, Chen Jianhao's whole body has been shocked.

He didn't expect that this gadget could actually discharge automatically.

"Remove this box!"

With the photon submachine gun in his hand, Wang Xuan pointed to the box containing the abnormal biological detector, and ordered Chen Jianhao.

Chen Jianhao took a look into the box and found that it was filled with temperature measuring guns.

He asked very puzzled: "What do you do with these temperature guns?"

"If you are told to move, you can move!"

"How can there be so much nonsense!"

Wang Xuan said.

"Yes Yes Yes!"

Chen Jianhao had no choice but to lift the packing box, then left here with Wang Xuan, and returned to the previous place.

"Wang Xuan, these seem to be temperature measuring guns!"

"What do you collect these things for?"

Liu Ruoruo, Bai Xiaomeng and others were very puzzled, why did Wang Xuan collect so many temperature measuring guns.
