A hundred level-ten coolers could indeed cover this not-so-large safety zone.
However, the cooling effect might not be so great, as the external temperature is too outrageous, and it will definitely continue rising tomorrow.
In such conditions, ordinary aircraft can no longer leave the cooling range; they will be scrapped instantly upon entering the high-temperature environment.
Even many specially modified ones won't work.
Yang Yuan didn't even eat; after upgrading the coolers, he continued assembling the Firepower Flying Disc.
Apart from Chen's Staff occasionally leaving to handle some miscellaneous matters, the three leaders spent almost all their time working overtime with Yang Yuan.
Suddenly, a soldier ran over, saluted, and then said loudly, "Report, the energy of the first Firepower Flying Disc is about to run out. Should we replace the Energy Core? Please instruct."
Jia Weixin didn't make a decision on his own but looked at Yang Yuan.
"Bring it over," Yang Yuan said.
The soldier looked at his group leader.
"Bring it over," Jia Weixin said.
Soon, the first Firepower Flying Disc assembled yesterday was maneuvered into the factory building.
Yang Yuan glanced at the experience and found that it already exceeded a thousand; if consumed directly now, it could be upgraded to level five or six in one go.
But doing so would certainly burst the factory, and with so many Firepower Flying Discs needing upgrades, it would directly cover the sky, blocking the view. Now wasn't the time for a complete upgrade.
Therefore, he moved the disc to level two with a thought.
The next moment, under everyone's astonished gazes, the two-meter diameter Firepower Flying Disc swelled with the wind, instantly growing to a four-meter diameter, and its thickness doubled.
"This..."
"Hiss!"
"It looks so surreal!"
Including Jia Weixin, everyone wore an astonished expression, witnessing Yang Yuan's abilities for the first time.
However, it wasn't over yet, because at this moment, a soldier, eyes wide, ran in holding the tablet controlling this Firepower Flying Disc, approaching Jia Weixin.
Jia Weixin looked at the data displayed on it and was once again stunned, "The number of shells doubled, endurance time doubled, range doubled, and the Bluetooth signal, that is the remote control distance, also doubled?!"
"What?" Leader Chen hurried over to take a look, also showing an expression of disbelief.
"So magical!"
Having finished his tasks, Chen Xianzhi also saw the data, and a look of joy flashed in his eyes, "The caliber of the shells really did double; Mr. Yang Yuan's abilities are truly magical."
Yang Yuan squatted down to continue assembling the Firepower Flying Disc, saying, "The same goes for the other Firepower Flying Discs; just bring them if their energy is about to run out."
The soldier nearby looked at his group leader.
Group Leader Jia Weixin said, "Do as he says, from now on, Mr. Yang Yuan's words are my words."
Those around were all shocked; this was no small authority, equivalent to Yang Yuan being second only to the leader of the thirteenth squad.
Yang Yuan also looked at Jia Weixin in surprise, quite bold, not afraid he might cause trouble?
Jia Weixin said candidly, "Now we are in desperate straits, if Mr. Yang Yuan can help us all through this ordeal, your contributions will be worthy of any official position."
Yang Yuan raised an eyebrow, smiled, but didn't respond.
Compared to an official position, he actually preferred freedom, as official positions are tied to responsibility.
Time passed.
Afterwards, every hour, Yang Yuan upgraded a previously assembled Firepower Flying Disc once.
During this period, Leader Chen left briefly, and when he returned, he looked somewhat embarrassed, whispering something in Jia Weixin's ear.
Jia Weixin revealed a shocked expression, then somewhat awkwardly said to Yang Yuan, "Mr. Yang Yuan, previously Leader Chen calculated that a four-meter-diameter Firepower Flying Disc, counting all internal components, seemingly cannot fit two thousand similarly enlarged shells, so in curiosity, one was disassembled for research..."
Yang Yuan looked up, curiously asking, "And the result?"
Leader Chen replied, "The result was, after disassembly, like popcorn, many extra shells sprayed out, and then those shells couldn't be put back. I've researched, and there's no phenomenon of spatial folding inside the Firepower Flying Discs, truly strange."
"Conceptual objects don't follow the rules of physics."
Yang Yuan, though also feeling it was magical, said justifiably, "Put as many shells in as you can, then bring it over for me to see."
After all, they were his own conceptual objects, and his subconscious was always of this belief, perhaps the rules of those objects were all influenced by his subconscious.
And concepts, to some extent, are closely related to one's subconscious.
But the conscious and subconscious are not directly connected, so though Yang Yuan had some expectations about his upgraded items' abilities, he didn't know the exact details.
"Okay."
Leader Chen immediately had someone bring over the Firepower Flying Disc he disassembled.
Soon, this level-two Firepower Flying Disc entered the factory building.
Yang Yuan glanced at it, finding that the experience data was still there, but the shell count directly decreased by two hundred, leaving only one thousand eight hundred.
And now the ammunition bay displayed that it was full and not in a damaged state, so experience couldn't repair it.
He sighed and had the soldiers continue to gain experience, not saying much else.
He couldn't exactly scold Leader Chen after all; he was a big shot academician.
It was just unfortunate to be short by two hundred shells; these two hundred shells would double after upgrading, and their power would soar, possibly yielding decisive effects.
"Sorry, Mr. Yang Yuan, I didn't know this would happen," though Yang Yuan didn't say anything, Leader Chen still felt embarrassed.
"It's okay."
Yang Yuan continued assembling the remaining Firepower Flying Discs, curiously asking, "Did Leader Chen discover anything in the research?"
Mentioning this, Leader Chen's eyes lit up immediately, "Although the capacity of the ammunition bay is very peculiar and incomprehensible, the gun barrel and other components have been optimized, and some details are entirely worth referencing."
Yang Yuan's eyes flickered, thinking if there were some scientific principles behind the things he upgraded, perhaps the other side could examine his Power Armor, then upgrade it with newer Power Armor.
The effect of upgrades in that case would certainly be better.
This thought fleetingly crossed his mind, and he didn't say much more.
Soon, another day passed.
The external temperature increased even further, and after testing, the highest external temperature on this day reached an astonishing two hundred and fifty degrees; even things with high ignition points were lit by those with low ignition points.
Outside was full of fire, the real spark setting the prairie ablaze, burning the entire world.
In this area, only the safety zone on the periphery of the Ancient Ruins remained in a low-temperature state; all other areas turned into a world of flames.
All wind Superpower Users stationed in the safety zone prevented tornadoes from forming and blew away the smoke drifting in with the wind.
Otherwise, the smoke alone would be unbearable for everyone in the safety zone.
That afternoon.
At the canteen door in the safety zone, a woman suddenly fainted while queuing for food.
Immediately thereafter, like an infection, more women fainted one after another.
This scene startled everyone around.
