"Eighty kilometers..."
Yang Yuan frowned, "Have all the small Drought Fiends within five hundred kilometers been cleared? What's the temperature outside the safety zone now?"
The light and heat emitted by the Drought Fiends are relatively balanced and do not increase rapidly. In fact, even the body of a Drought Fiend is not that hot. The real heat comes from its radiative energy.
Or rather, the state manifested by that radiative energy is heat.
"Around two hundred and twenty degrees, and it will definitely continue to rise..."
Chen Xianzhi looked extremely solemn, "Once the real Drought Fiend gets within eighty kilometers, the temperature here will at least reach five or six hundred degrees Celsius! With the cooling device you've made, pure temperature is not a problem, but that power of Reversing Yin and Yang is the biggest threat. By then, all the women here may die or be transformed into small Drought Fiends."
Saying this, he glanced obscurely at the metal house behind Yang Yuan, which housed Yang Yuan's two companions, both female.
Yang Yuan furrowed his brows deeply. He glanced at his Firepower Flying Disc from afar and realized it would still take two full days to reach level ten, so he said, "Just in case, it seems we need to make another round of preparations. Do you have any space-related materials?"
"Uh... I don't think we do," Chen Xianzhi shook his head.
Yang Yuan said, "Are there any Superpower Users with space abilities? That Space Carrier should belong to the space-related Superpower Users, right?"
"Of course. Do you have a plan?" Chen Xianzhi asked.
"I do have a way, but it might require the Space Carrier to make a little sacrifice. Of course, it won't harm his life. As for his loss, I can promise to craft a weapon for him. Whether he agrees or not, you decide," Yang Yuan said.
"No problem." Chen Xianzhi nodded.
Yang Yuan said, "Alright then, you take that Superpower User to the research department first, and I'll come shortly."
"Alright."
Due to the urgency of the situation, Chen Xianzhi didn't question how Yang Yuan planned to proceed.
After all, everyone was in the same boat, and he believed Yang Yuan wouldn't play any tricks at a time like this.
Once Chen Xianzhi left, Yang Yuan put down the Plum Blossom Dart he was assembling and went to the corner of the factory.
Here, a large group of people were throwing Plum Blossom Darts, each with one, and someone was responsible for retrieving them.
By this time, quite a few nearly broken ones were piled up beside them.
Yang Yuan casually picked one up and glanced at it:
[Plum Blossom Dart Lv.1: 5943/Repair]
The repair cost wasn't much, only taking five points.
After repairing it, he began to enhance it:
[Plum Blossom Dart Lv.1: 5938/3 (Hidden weapon; Upgradable)]
...
[Plum Blossom Dart Lv.2: 5935/6 (Hidden weapon; Upgradable)]
...
[Plum Blossom Dart Lv.3: 5929/12 (Hidden weapon; Upgradable)]
Upon reaching level three, although the information hadn't changed, the feel indicated a significant change in material.
It seemed more suited as a material for hidden weapons, and it was sharper and overall optimized.
...
[Plum Blossom Dart Lv.4: 5917/24 (Range increased by ten meters; Upgradable)]
Range started to increase.
'This range increase should be based on anyone's basic range, right?'
After all, because everyone has different strength, the distance their hidden weapons reach is different, and this increase in range is on top of the original range.
With this in mind, Yang Yuan continued upgrading.
...
[Plum Blossom Dart Lv.5: 5893/48 (Range increased by twenty meters; Upgradable)]
...
[Plum Blossom Dart Lv.6: 5845/96 (Range increased by forty meters; Upgradable)]
...
[Plum Blossom Dart Lv.7: 5749/192 (Range increased by a hundred meters; Piercing trait added; Upgradable)]
The level seven Plum Blossom Dart gained a piercing trait, greatly increasing its lethality.
Moreover, this piercing trait somewhat reduces air resistance, weakens wind drag and whistling sounds, and enhances concealment.
...
[Plum Blossom Dart Lv.8: 5557/384 (Range increased by two hundred meters; Piercing trait added; Upgradable)]
...
[Plum Blossom Dart Lv.9: 5173/768 (Range increased by four hundred meters; Piercing trait added; Upgradable)]
...
[Plum Blossom Dart Lv.10: 4405/1536 (Range increased by a thousand meters; Piercing trait added; Armor Piercing trait added; Upgradable)]
The level ten Plum Blossom Dart had an additional Armor Piercing trait.
'Not bad.'
Yang Yuan continued upgrading, curious to see what the Plum Blossom Dart would become after reaching Marvel status.
...
[Marvel·Plum Blossom Dart Lv.11: 0/6 (Range increased by two thousand meters; Piercing, Armor Piercing, Invisibility traits; Not Upgradable)]
The level eleven Plum Blossom Dart had turned a dark color, a completely non-reflective black.
Even with this color, it could easily achieve optical invisibility in the air, and with the piercing trait reducing wind resistance...
Perhaps, even without the Invisibility trait, it might achieve some degree of invisibility.
"Nice."
Yang Yuan glanced at his personal experience, which indeed had increased by a point. He then set the upgraded Plum Blossom Dart aside and picked up an unupgraded one to continue upgrading.
That night, he crafted many Plum Blossom Darts. Although many lacked enough experience, he managed to accumulate over four hundred personal experience points.
In less than half an hour, he finished upgrading all the Plum Blossom Darts with sufficient experience.
[Lv.17: 474/128 (Upgradable)]
'Over four hundred experience, enough to level up twice.'
With anticipation, Yang Yuan began upgrading.
...
[Lv.18: 346/256 (Upgradable)]
...
[Lv.19: 90/512 (Not Upgradable)]
'Level nineteen, about fifteen hundred Marvel experience points short. I'll try to reach level twenty-one by tomorrow morning, at which point the experience should refresh again.'
Yang Yuan slightly adapted to his surging physique and strength, then placed the four hundred and thirteen Marvel Plum Blossom Darts he had upgraded before into a wooden box.
He carried the box to Storm, saying, "Let trustworthy people supervise and call more regular people to continue throwing these Plum Blossom Darts. But be careful this time; make sure ordinary people throw them, don't use Superpower Users, and definitely don't throw towards areas with people since these Plum Blossom Darts are very powerful."
After saying this, he left the factory and quickly headed towards the research department in the safety zone.
"Very powerful?"
Storm skeptically picked up a Plum Blossom Dart, no more than five centimeters in diameter, "How powerful can it be?"
She glanced at a tree a hundred meters outside the factory and tried to throw it without much force.
"Boom—"
"Boom!"
As soon as she released the Plum Blossom Dart, it left no visible trace, but the tree a hundred meters away was directly pierced through, and the Plum Blossom Dart continued, piercing through the safety zone wall and shooting into the distance, disappearing from view.
Instantly, Storm's eyes widened, "How is this possible? I didn't even use force..."
After the initial shock passed, her expression suddenly changed, "My Marvel..."
