The fire source stone is a new energy discovered by human beings after entering the 22nd century, because the heat and huge energy generated by the burst of the fire source stone have allowed human beings to use them in the development of weapons.

And after the end of the world, this incendiary weapon has no effect on monsters, and the mining of fire source stones has stalled.

But I didn't expect the Fire Source Stone to come in handy at this time.

Ji Zhan took out a small bag that was only the size of a palm from the material box, and the small bag was strung with rope so that it could be carried around.

Ji Zhan pinched it lightly, feeling that the bag contained a substance similar to powder.

"The fire source stone bag contains the fire source stone that has been ground into powder, so that a small bag can produce the heat that a person needs for a day. The method of use is also very simple and convenient, as long as you wear it close to your body, the normal body temperature of human beings is enough to wake up the igneous stone powder from its dormant state, and then continue to burst out of heat. ”

After hearing the conversation between Ji Zhan and Yu Wu, the people in an armed team next to him couldn't help but interject to explain.

But obviously he was also a little careful, he secretly glanced at Ji Zhan's side face, and after Ji Zhan turned his head to look at him, his face turned red and his heart was moved.

Ji Zhan looked at him coldly, and said in a light tone, "Thank you." ”

"No...... You are welcome! Xu is still a stunned young age, after being thanked by Ji Zhan so bluntly, he shyly ran away to continue his work, but still looked at Ji Zhan from time to time.

Yu Wu found that the man was snooping on Ji Zhan, and he didn't know where he got the guts, so he ran to the other side of Ji Zhan and stood there, and glared back at the man.

Ji Zhan didn't pay attention to the silent smoke between the aftermist and the man, but he was very interested in the fire source stone bag in his hand.

Since there is this thing, if it had been taken out two years ago, so many people would not have frozen to death every winter.

The youngest of the students who froze to death last year was only eight years old.

Ji Zhan couldn't say whether he was feeling pity or sadness at that time, but it was hard to forget that scene.

……

After a busy morning, Ji Zhan finally had time to find Jing Sa during the lunch break.

As soon as Jing Sa finished arguing with the people of the district management team, the person in charge of the district management team left with a displeased face, and Jing Sa didn't seem to be affected by anything, obviously the district management team didn't get any benefits from him.

Jing Sa saw that Ji Zhan happened to come, so he wanted to go over and talk to her.

But Qiu Jing suddenly stopped in front of him at this time, and said: "Major, now you are delivering supplies to the outer base on behalf of the inner base, in order to alleviate the dissatisfaction of the outer base with the top management these days, I also ask you to go out for a walk during your break, and occasionally do what you can, so that they can see the sincerity of our inner base." ”

Qiu Jing's words have been said very tactfully, to put it bluntly, she hopes that Jing Sa can do some face projects for the people in the outer base.

Jing Sa's eyes widened in surprise because of Qiu Jing's words, but the surprise was fake, and the ridicule was true, he said, "Do you think that if I go out and give them a little favor, they will be grateful to us?" ”

"Qiu Jing, is there something wrong with your thoughts?"

Qiu Jing was stunned for a moment, and at Shangjingsa's mocking gaze, she was indescribably flustered in her heart.

"Major, I'm ......"

"We give them supplies, that's what they deserve, and without the labor of the outer base, the whole base will be at a standstill. Although they can't go to the wild to kill monsters, their labor force ensures the normal operation of the base, so the people in the inner base and the people in the outer base are obviously equal, and there is only a relationship between mutual use, why do we become a superior existence to them in your mouth? ”

"Qiu Jing, you are really a ...... Strange people, the word feudalism is obviously about to be exhausted in the long river of human history, but now you have to translate it again and show it to us. Jing Sa smiled evilly, and the words he said were like quenching poison, "But it's really funny, after all, who doesn't like to watch clown performances?" ”

The clown is, of course, Qiu Jing, who thinks she is smart, and those behaviors that Qiu Jing thinks are smart are just a funny drama in Jing Sa's eyes.

Jing Sa saw that Qiu Jing was panicking because of his words at the moment, and his mood became a little happy.

This kind of stepping on people's pain points, seeing their helpless appearance, is indeed fun for him.

He didn't say such things because he sympathized with the people in the outer base, he just felt that Qiu Jing's high-minded appearance made him feel a little disgusted, so he lifted her fig leaf.

"Major, I didn't mean that, I also thought about the base, I ......" Qiu Jing hurriedly wanted to explain.

"But the commander didn't give the instructions you just said, you're just an adjutant in the service group, and when I don't allow you to think, you just need to use it as a tool." Jing Sa saw Ji Zhan standing not far away waiting for him, and he had no patience with Qiu Jing at the moment, and when he said the last sentence, there was a strong warning in his voice.

After speaking, Jing Sa left the depressed Qiu Jing and walked to Ji Zhan's side.

With Ji Zhan's ear, of course she also heard what Jing Sa said to Qiu Jing just now, she was not interested in Jing Sa's work, she just raised the fire source stone bag in her hand and said, "It's the first time I know that there is this thing in the base." ”

Jing Sa touched the top of Ji Zhan's hair and asked, "Are you tired?" ”

Ji Zhan shook his head, it was just to move things, and it didn't take much effort.

Jing Sa took the fire source stone bag in Ji Zhan's hand and said, "When I fought with the Flying Fish Monster, the energy in the automatic quantum cannon used came from the fire source stone. ”

Ji Zhan was stunned for a moment, she remembered the monsters she saw during the battle that were shot down by the automated quantum cannon, and after those monsters were hit by the quantum cannon, the crystal nuclei were melted, and they lost the ability to regenerate.

"But the heat generated by the fire source stone is obviously not enough to melt the crystal nucleus, and the army has tried it at the beginning of the last days." There are all kinds of weapons in the military academy, and during the war of the end times, they also used incendiary weapons that used fire source stones as energy, but they didn't work against monsters at all.

"The heat that the fire source stone can generate is actually far more than 600-800 °C, but in the past, the research institute could only activate the ability of the fire source stone to that level, but now the research of the base on the fire source stone has gone one step further, and the instantaneous temperature of the quantum cannon can reach 20,000 °C."

Human beings will continue to think in order to survive in desperate situations, and as long as there is still a breath of air, human beings will not give up thinking.

In fact, human beings have been evolving all the time, not in terms of strength and racial evolution like monsters, but in the continuous evolution of mind and intelligence.

Use your brain to imagine the future, and then use your hands to create miracles.
