The corners of Yang Yuan's mouth curled, the muzzle of the gun was slightly raised, and he pulled the trigger again.

"Boom-"

The pistol made no sound, as if it were not him, but there was a large explosion in the direction the muzzle was pointing, that is, in the crowd of stones.

There were rocks and smoke in the air.

Nothing can be seen.

Zhao Jiayan and Jiang Yiyi's eyes widened, wanting to see the situation inside the smoke and dust for the first time.

Eventually, when the smoke cleared, there was no stone monster left in the area.

Not only that, but the stone forests within 20 meters of the surrounding area were also destroyed.

"Wow!!" Jiang Yiyi's small mouth was so wide that she could stuff a duck egg.

Zhao Jiayan was also a little distracted.

Back in the day, they just met an ordinary alien beast giant wolf, and they had to flee for their lives, and finally killed it in the end.

An ordinary stone monster encountered in the back also fired nearly ten bullets before it was solved.

But now, the pistol is still the same pistol.

But the current power of that pistol, with just one shot, directly killed a group of ordinary stone monsters with at least hundreds of heads.

Even, that kind of elite-level stone monster couldn't withstand two shots!

Yang Yuan quickly returned to Zhao Jiayan's second daughter with the remaining bullets, and returned Zhao Jiayan's pistol to her: "Your gun has been strengthened for you." Stay here, be careful, I'll go get the Spirit Core back. ”

With that, he stepped out of the radiant range of the cooler once more and strode towards the location of the dead stone monsters.

He had never tried his speed since he leveled up again, and now as soon as he started running, he found that he could easily run fifty or sixty meters per second.

And this speed is not the maximum speed.

Zhao Jiayan and Jiang Yiyi also discovered Yang Yuan's amazing speed, although they were also a little surprised.

But compared to the previous situation when Yang Yuan used a pistol to shoot a heavy cannon, this point in front of him didn't seem to be a big deal.

……

Yang Yuan's main ability is to upgrade items, and the enhancement of physical strength is almost incidental.

Although the level of an item is limited by its own level, it seems that it is the main thing, but when it comes to lethality, it is obviously the item that is the main thing.

And his ability, the power of the upgraded item, is related to the initial quality.

In other words, even if an item of the same level has a higher initial mass, the more powerful it will be after it reaches a certain level.

It's like a pistol and that fire frisbee.

The current pistols are already level 11, but in fact, the power is not necessarily as big as that of a level 6 firepower frisbee.

Soon, Yang Yuan came to the location of the corpse of the elite-level stone monster.

He scanned the somewhat unstable radar of the power armor and quickly found the wreckage where the core was located.

It was a two-meter huge stone, and although it had cracked, it still took a lot of effort for him to completely break it away and get the spirit core inside.

"What a lot of energy!"

Yang Yuan picked up the goose egg-sized spirit core and found that it contained a huge amount of energy that could be clearly felt.

Judging from the amount of energy contained, the energy contained in this spirit core is at least thirty times stronger than that of ordinary spirit cores.

If the quality of the energy is also more advanced, this level of spirit core is at least a hundred times more precious than ordinary spirit core.

"Good stuff!"

He smiled and put it away, and went back to find the core of the ordinary stone monsters.

Although those ordinary stone monsters were blasted everywhere, through the radar of some unstable power armor, he still found all of them.

Ordinary spirit cores, there are only one hundred and eight.

Now there are more than two hundred spirit cores on his body, which is already a lot of money.

Holding all the spirit cores in his hand with a net woven by grass and vines, Yang Yuan came to the edge of the crater that was hit by the strange pistol, looked in, and found that the crater was three meters deep and more than twenty meters in diameter.

You know, this is a rocky mountainous area, and there are hard stones everywhere.

In the case of muddy areas, the damage caused is even greater.

"Tsk, this power ......"

Yang Yuan was a little skeptical, conventional missiles may not have this power, right?

He didn't waste any time here, and when he was done, he turned and walked back.

By this time, the sun had set in the west, and the sky was getting dark.

However, the temperature is still high, and there is a tendency to get higher and higher.

The little droughts killed by those eight tool men didn't seem to be able to keep the temperature back at all.

"The experience of the Firepower Frisbee should be enough to go up another level."

In the process of walking back, Yang Yuan estimated the time, and then hesitated a little.

Because he didn't know what level the Fire Frisbee had to be upgraded to in order to kill the Dryfish.

And as the level gets higher and higher, the volume of the fire frisbee will get bigger and bigger, and it is easy to make it a very obvious target, unless the fire frisbee is parked far away.

But then it's easy to be destroyed by monsters or other unsuspecting abilities.

So Yang Yuan thought about it, and decided to wait for the experience to be enough, and then rise to the eleventh level in one go.

At that time, whether it is to exterminate the drought fish, or to use it as a floating island to lead people to escape, it will be enough.

Because according to the fact that the diameter of the firepower frisbee will double every time it is upgraded, the diameter of the eleventh level of the firepower frisbee will definitely exceed one thousand meters!

A fire frisbee with a diameter of more than 1,000 meters, it's exciting to think about!

"Shhh...... It's so cool here! ”

The moment he returned to the radiant range of the cooler, Yang Yuan almost groaned in comfort.

Outside, even with his current physical fitness, he will feel uncomfortable.

Although the heat of hundreds of degrees Celsius could not hurt him, it could already make his hair and clothes curly, and ordinary people would be directly roasted when they entered such an environment.

Handing over the spirit core to Zhao Jiayan, Yang Yuan came to the door of the safe house and looked at the experience of the safe house:

[Solar All-in-One Portable House LV.3: 105/20 (Upgradeable)]

There are so many safe house experiences.

Yang Yuan's heart moved, and he directly began to upgrade.

A white light that only he could see emitted and lasted for half a minute, and after half a minute, the safe house reached level four.

[Solar integrated portable house LV.4: 85/40 (portable safe house, password explosion-proof door, built-in solar lighting, already has a certain security; Upgradable)]

Compared with the third level, there is an additional password explosion-proof door, and the original inlaid door latch has become a combination lock.

In this way, the door can be locked whether it is outside or inside, and it is easier to enter and exit.

The password is eighteen digits, which is not bad.

After Yang Yuan set the password, he continued to upgrade.

A minute later, the safe house reached level five.

[Solar integrated portable house LV.5: 45/80 (portable safe house, password explosion-proof door, built-in solar lighting; Not upgradable)]

Level 5 safe house, that is, the 'already have a certain amount of security' has been deleted.

Obviously, the current safe house can be regarded as a real safe house.

That's pretty good.

Except for being lighter, there are no other shortcomings, but after the later level goes up, it should be able to make up for this shortcoming.

Yang Yuan glanced at the safe house with satisfaction, which had hardly changed from the outside, and then entered it and took out the cooler in the water bag.

The experience of the cooler has long been exceeded, and it was previously a personal level limit, so it is impossible to continue to level up.

Now it's time to move on to the upgrade.
