Yang Yuan's lips curled upwards, the gun slightly raised, and he pulled the trigger again.
"Boom——"
The pistol made no sound, as if it wasn't him who fired, but the direction the gun pointed in, right in the stone creature horde, exploded directly.
The rocks flew into the sky, and dust filled the air.
Nothing could be seen.
Zhao Jiayan and Jiang Yiyi both widened their eyes, trying to quickly see the situation inside the dust cloud.
Finally, when the dust settled, not a single stone creature remained in that area.
Moreover, the stone forest within a 20-meter radius was completely destroyed.
"Wow!!" Jiang Yiyi's small mouth was so wide open that a duck egg could fit inside.
Zhao Jiayan was also a bit dazed.
He recalled how they once encountered an ordinary exotic giant wolf, and had to run for their lives, barely managing to kill it in the end.
The ordinary stone creature they encountered later took nearly ten bullets to take down as well.
But now, the pistol is still the same pistol.
Yet, the power of that pistol now can kill a horde of at least a hundred ordinary stone creatures with just one shot.
Even the elite-level stone creatures couldn't withstand two shots!
Yang Yuan quickly returned to Zhao Jiayan and Jiang Yiyi with the remaining bullets and handed the pistol back to Zhao Jiayan: "I've enhanced your gun for you. You two stay here and be careful, I'll go retrieve the Spirit Monster Core."
With that, he stepped out of the cooler's radiation range again, striding towards the location of the fallen stone creature horde.
Having upgraded again, he hadn't yet tested his speed, but as soon as he started running, he found that he could easily reach speeds of fifty to sixty meters per second.
And this wasn't even his maximum speed.
Zhao Jiayan and Jiang Yiyi also noticed Yang Yuan's astonishing speed, though they were somewhat surprised.
Compared to when Yang Yuan used the pistol to produce a heavy cannon effect, this sight seemed like nothing.
...
Yang Yuan's main ability is upgrading items, with physical strength enhancement being almost secondary.
While the item's level is limited by his own level, it seems that he himself is the main factor, but in terms of destructive power, the item is evidently the main factor.
Moreover, the power of the item he upgrades is related to its initial quality.
This means that even if the items are the same level, the higher the initial quality, the greater the power will be once it reaches a certain level.
Just like the pistol and the Firepower Flying Disc.
The current pistol is already level eleven, but its power might not even match the level six Firepower Flying Disc.
Soon, Yang Yuan reached the site of the elite-level stone creature's corpse.
Using the somewhat unstable radar of the Power Armor, he quickly found the wreckage where the core was located.
It was a two-meter-tall boulder. Despite being cracked, he still exerted a lot of strength to completely open it and take out the Spirit Monster Core inside.
"Such strong energy!"
Yang Yuan picked up the Spirit Monster Core, the size of a goose egg, and sensed the immense energy clearly contained inside.
From the amount of energy contained, this Spirit Monster Core contains at least thirty times the energy of a regular Spirit Monster Core.
If the quality of the energy is also higher, this level of Spirit Monster Core is at least a hundred times more valuable than a regular one.
"What a treasure!"
He smiled and put it away, then started searching for the cores of the ordinary stone creatures.
Though the ordinary stone creatures were blown everywhere, he found every single one using the somewhat unstable radar of the Power Armor.
There were 108 regular Spirit Monster Cores.
Now he had over two hundred Spirit Monster Cores on him, which was quite a fortune.
Wrapping all the Spirit Monster Cores in a makeshift net made of vines, Yang Yuan arrived at the edge of the crater created by the Marvel Pistol and looked inside, discovering that it was three meters deep with a diameter of over twenty meters.
Bear in mind that this is the Stone Mountain District, with solid rocks everywhere.
If it were the Mud Mountain District, the destruction would be even greater.
"Tsk tsk, this power..."
Yang Yuan suspected that conventional missiles might not even have this power?
He didn't waste time here, satisfied with the sight and then turned to head back.
By now, the sun was already setting, and the sky was gradually darkening.
However, the temperature remained high, even showing signs of rising further.
The small Drought Fiends killed by those eight tools didn't seem to be able to lower the temperature back down.
"The Firepower Flying Disc's experience should be enough for another level up."
On the way back, Yang Yuan estimated the time and hesitated.
Because he didn't know what level the Firepower Flying Disc needed to reach to kill the Drought Fiend.
And as it levels up, the Firepower Flying Disc will get bigger, making him a very conspicuous target unless it's placed far away.
But doing so would make it susceptible to monsters or other uninformed Superpower Users damaging it.
So Yang Yuan thought it over and decided to save up enough experience and then level up to level eleven in one go.
At that point, whether it's used to destroy the Drought Fiend or serve as a floating island for escape, it would be sufficient.
Because as the Firepower Flying Disc's level increases, its diameter doubles, and at level eleven, its diameter will definitely exceed a thousand meters!
Thinking about a Firepower Flying Disc over a thousand meters in diameter is exciting!
"Hiss... it's really cool here!"
Returning to the cooling radiation range brought Yang Yuan such comfort that he almost groaned out loud.
Outside, even with his current physique, he felt discomfort.
Though the temperature over a hundred degrees Celsius couldn't harm him, it was enough to curl his hair and clothes. Ordinary people entering such an environment would be roasted alive.
Handing the Spirit Monster Cores to Zhao Jiayan, Yang Yuan went to the entrance of the Safe House and checked its experience:
[Solar-Powered Portable House LV.3: 105/20 (Upgradeable)]
The experience for the Safe House was unexpectedly high.
Inspired, Yang Yuan began upgrading immediately.
The white light, visible only to him, shone out, and after half a minute, the Safe House reached level four.
[Solar-Powered Portable House LV.4: 85/40 (Portable Safe House with Password-Protected Blast Door and Built-In Solar Lighting; Upgradeable)]
Compared to when it was level three, it had acquired a password-protected blast door, and its original inset latch was now a digital lock.
With this, one can lock the door whether inside or outside, making entry and exit more convenient.
The password is an eighteen-digit number, which isn't too bad.
After setting the password, Yang Yuan continued upgrading.
One minute later, the Safe House reached level five.
[Solar-Powered Portable House LV.5: 45/80 (Portable Safe House with Password-Protected Blast Door and Built-In Solar Lighting; Non-Upgradable)]
At level five, the phrase 'with certain security' was removed.
It was clear that the current Safe House could truly be considered a Safe House now.
This was quite satisfactory.
Aside from being a bit lightweight, there were no other drawbacks, but as it continues to upgrade, it should compensate for this shortcoming.
Yang Yuan gave a satisfied glance at the Safe House, which looked almost unchanged on the outside, then went inside to take out the cooler from the water bag.
The cooler's experience was already excessive, previously limited by his personal level and unable to upgrade further.
Now, upgrading could continue.
