Everyone is fleeing the famine, my items can be upgraded

He hurriedly looked at the pistol's data:

[LV.4: 61/40 (upgradeable)]

Sure enough, the experience is already full.

No, it's all over the limit.

Yang Yuan felt happy and hurriedly chose to upgrade.

A white light that only he could see appeared and lasted for about three seconds before the pistol was upgraded.

However, in this upgrade, the pistol has not changed much, that is, it is more refined, but the shape and size remain the same.

[LV.5: 21/80 (King of pistols, effective range of 200 meters, will produce an explosion effect after hitting the target.)]

Judging from the introduction, it seems that the range has only been doubled, and the power is not yet clear.

Yang Yuan looked around through the external radar of the power armor and found that there were no other creatures within a hundred meters, so he raised his pistol and aimed at a tree trunk in the distance.

He decided to find out the power of the pistol first to avoid misjudgment the next time he encountered a powerful enemy.

"boom!"

There was a loud noise, and the thigh-thick tree trunk was blown open, sending sawdust flying.

Then he aimed at the trunk of the tree.

There was a loud "boom", and a bowl-sized hole was blown out of the surface of the giant tree.

But that's about it.

"What's wrong? Are there any enemies?" Zhao Jiayan asked nervously, preparing to use her powers to help.

"I'm going to test the gun," Yang Yuan said.

He walked under the giant tree and observed the hole made by the bullet. He found that although the surface of the hole was only as big as the mouth of a bowl, the inside had turned into powder.

As for the pistol bullets, they had been annihilated long ago, and even the powder could not be found. The kinetic energy turned into terror was transformed and disappeared.

He put his hand in and easily pulled out a large amount of sawdust. He stretched his arm completely until the end of the hole turned into hard wood.

"Half a meter deep?"

Yang Yuan was a little surprised and surprised: "As expected, the explosive power of this pistol bullet is comparable to a grenade at most, or even worse. But the real lethality of firearms is mainly based on penetration, and surface wounds It doesn’t represent real power.”

The trunk of this giant tree is very hard and can create such a big hole. Ordinary beasts will definitely not be able to withstand it.

Zhao Jiayan and Jiang Yiyi both looked at the tree hole that Yang Yuan had hollowed out in surprise.

Zhao Jiayan felt that with such power, if he fired a few more shots, he could create a tree hole for temporary residence.

"Let's keep going and hold on a little longer." Yang Yuan said, while taking a look at the power armor experience and found that it was full with more than an hour left.

"Uh-huh."

Neither Zhao Jiayan nor Jiang Yiyi had any objections. Even the eight-year-old Jiang Yiyi knew that she must not stop at this time, otherwise her legs would become weak and she would only become more tired as she walked.

This is what she has learned over the past six months.

Zhao Jiayan saw Yang Yuan's open mask and the sweat flowing freely on his face, and asked with some worry: "Do you want to drink some water? You sweat so much, if you get dehydrated..."

"No, it's best not to open the water bag now, otherwise the water inside will evaporate." Yang Yuan said.

Although I am very thirsty, I have not reached the point where I cannot stop drinking.

"It shouldn't evaporate. I got a cooler when I bought water before. This cooler can really lower the water temperature." Zhao Jiayan said.

"Cooler?"

Yang Yuan's eyes lit up: "Where is it? Show it to me quickly."

"It's inside the water bag." Zhao Jiayan hurriedly opened the water bag and took out the cooler soaked in it.

'Huh? Is this the one I made last night? ’

Yang Yuan took the cooler and found that the temperature of the cooler was only 25-6 degrees, which was much lower than the outside temperature of 40 degrees.

Apparently this thing actually cools water.

But what really surprised him was that there was a lot of empirical data on this cooler.

‘I made a hundred coolers last night, weren’t those coolers put into the underground river? Or was it put in and taken out again? ’

Then, one of the things he made came back into his hands by accident?

[Cooler LV.1: 787/10 (upgradeable)]

‘Seven hundred and eighty-seven points of experience! ’

Yang Yuan was a little excited. It was the first time he saw that the items he assembled had so much experience.

‘I wonder how many levels this thing can be upgraded to? ’

He hurriedly chose to upgrade, wanting to see if the cooler would have a suppressive effect on the increasingly higher temperatures after the level became higher.

Soon, the first upgrade was successful.

[Cooler LV.2: 777/20 (contains water temperature adjustment pattern, which can lower the water temperature within a radius of ten centimeters when placed in water, to a minimum of 25 degrees. The closer to the cooler, the greater the cooling effect. Good, easily affected by the environment; can be upgraded)]

The introduction is much more detailed than before.

‘Does the water temperature regulate the pattern? ’

This thought flashed through Yang Yuan's mind, and then he continued to choose to upgrade.

[Cooler LV.3: 757/40 (Contains a water temperature adjustment pattern, which can lower the water temperature within a radius of 20 centimeters when placed in water, to a minimum of 25 degrees...can be upgraded)]

The range has increased, but the minimum water temperature has not changed.

"continue!"

[Cooler LV.4: 717/80 (contains a water temperature adjustment pattern, which can lower the water temperature within a radius of forty centimeters when placed in water, to a minimum of twenty degrees...can be upgraded)]

Great, the minimum temperature has dropped.

[Cooler LV.5: 637/160 (...eighty centimeters...twenty degrees...can be upgraded)]

…

[Cooler LV.6: 477/320 (...one point six meters...twenty degrees...can be upgraded)]

…

[Cooler LV.7: 157/640 (contains a temperature adjustment pattern, which can work immediately after being put into water. It can reduce the temperature within a radius of 3.2 meters to a minimum of 15 degrees. The closer it is to the cooler, the lower the temperature will be. The better the cooling effect, the easier it is to be affected by the environment; it cannot be upgraded)]

It only took more than ten seconds.

When the last upgrade ended, everyone, including Yang Yuan and Zhao Jiayan, suddenly felt the temperature drop rapidly.

The temperature in the air originally reached at least forty degrees, but in the blink of an eye, the temperature dropped to ten or twenty degrees.

The extremely cool feeling made the three of them almost unable to hold back their moans.

"Wow, it's so cool!" Jiang Yiyi shouted excitedly.

"Why... why is it so cool all of a sudden? Is there any danger?" Zhao Jiayan was much more alert and hurriedly pointed her pistol at the surroundings.

But soon, she discovered that the half of her body close to Yang Yuan was cooler, and at the same time, she also discovered that a little water vapor had condensed on Yang Yuan's palm.

"This is..." She suddenly looked at the cooler in Yang Yuan's hand.

"I repaired this cooler, and now it works better." Yang Yuan explained with a smile, feeling a little excited.

With this baby, you don't have to worry about the temperature rising in a short period of time.

Now, although the appearance of this cooler has not changed, it is still a fist-sized magic shape, but it has become much more refined, with mysterious lines visible to the naked eye appearing on the surface.

Those lines may be the so-called temperature regulation lines.

The first introduction is the water temperature adjustment pattern.

But after reaching level seven, the introduction information changed from the water temperature adjustment array to the temperature adjustment array.

Although only two words have changed, the meanings they represent are completely different.

"Repaired it..."

Zhao Jiayan was speechless, she roughly understood what was going on.

But she was happy to play dumb and said happily: "You have water vapor gathering on your hands. Can this cooler condense the water vapor in the air? Can we collect water in this way?"
