After the telegram requesting tactical guidance was sent, Yokoi waited in front of the radio for three whole days, but there was no news, and it seemed that the top brass of the 26th Division had been completely disappointed in him, and they didn't even bother to give him the order to cut his stomach, and let him fend for himself in Changjing County. Pen ~ fun ~ pavilion www.biquge.info

There were rumors in the barracks that if it weren't for Yokoi's sudden desire to kill the 'ghost' while negotiating a deal, how could there be so many things, how could there be four or five hundred casualties. Some angry soldiers even wanted to shoot him with a black gun, but they were suppressed, and the officers who had the opportunity to take over as Yokoi's commander were not fools, and if Yokoi died, the next thunderbolt might be himself, in this case, it was better to let Yokoi continue to live, at least let him live so that others would not have to suffer that torment.

Yokoi was uncomfortable, and Qin Han couldn't stand it. The explosives were returned, and the work of opening the mountain was underway, but the research work on the 107 rocket artillery could not be carried out in any case, and the research work on the rocket engine could not be carried out in any way.

"Old Qin, let's give up first, it's not appropriate to study rocket engines now." Zhang Fang looked at the simple diagram drawn by Qin Han and said.

"No, this can't be abandoned, rocket engines must be studied, and they must be studied." Qin Han said it categorically.

"Why? With only gunpowder, we can launch a rocket up to 3 kilometers away. Li Meng said.

"It's different, what if we want to launch a rocket to 5 km? What about 50 km? Qin Han insisted on his point of view.

"How is it possible, you can't see it for 50 kilometers." Li Meng denied.

"Why is it impossible? I can't see it for 5 kilometers, but now the artillery can hit 5 kilometers away." This time, Zhang Fang is helping Qin Han to speak, and helping people or not helping relatives is a common problem among intellectuals in this era.

Qin Han waved his hand to interrupt the argument between the two and said, "The rocket engine must be studied, even if it is not for war, it will be used for other purposes in the future." ”

"Other uses? What else can you do? Xiong Weihua was curious about what other uses Qin Han could come up with.

Qin Han said mysteriously: "Do you want to go to the sky to see?" Looking at the moon? If we make a big rocket and fly all the way up, will it fly to the moon? ”

What answered Qin Han was a bunch of white eyes and Li Meng laughed: "Don't take us for fools, go to the moon?" If you fill half of the fuel, we won't be able to come back, die. ”

In the laughter of everyone, Qin Han couldn't help sighing, this short-sighted guy still didn't believe in himself.

Zhang Fangren was real, seeing that Qin Han's mood was not high, and persuaded him: "Old Qin, don't think too much, we also know that you are right, but have you thought about it, what do you use as fuel?" If you don't solve this problem, even if you make an engine, it's useless, no. ”

"Fuel? Alcohol is fine. Qin Han frowned.

Xiong Weihua was a little speechless for a guy like Qin Han who lacked common sense, and said: "Alcohol is okay, but there must be a mixture, and it is impossible to have such a big thrust with alcohol alone, understand?" ”

For this aspect, Qin Han is indeed a layman, and the head of the Tao mentioned above is because it is written in the materials of the end of the world, "Still need a mixture?" What does a mixture mean? ”

"Liquid oxygen, liquid oxygen is fine, but we don't make anything with liquid oxygen." Zhang Fang directly pointed to the topic.

This time Qin Han really has no tricks, it's not that everyone doesn't work hard, fuel is indeed a big problem, if it is not solved, no matter how much research is done, it will be in vain.

Qin Han gritted his teeth for a long time and decided to go back to the end of the world, he remembered that there was a small liquid oxygen generator in a hospital occupied by mutated creatures, but he didn't know if it could still be used.

The sky of the end of the world is full of colorful light at all times, and the air is filled with the smell of radiation dust, and you can't help but feel depressed when you come here. Qin Han sneezed twice, rubbed his nose that was nourished by the pure air, looked up at the sky, cursed in a low voice, withdrew his gaze and continued to observe the target of the action, the XX City Hospital.

The half-collapsed hospital had been covered in a mass of red mutant plants, and it looked like a red beast lying there, ready to devour anyone who came close.

Those mutated plants are not good, and the plants that survive on light and action alone in the last days have long been extinct, and those that can survive are either highly toxic or carnivorous plants. Qin Han's luck is good, this red mutant plant called Blue Liquid Teng is only highly poisonous, as long as you are careful, it is not a big problem.

Qin Han inspected all the weapons and equipment he carried, including: .50 caliber sniper rifles, .45 caliber and 9mm caliber combat pistols, large dog-legged scimitars, and 107D heavy combat knives. In addition, there is protective equipment such as individual armor and tactical helmets.

Taking a deep breath and taking out the "personal platform", Qin Han confirmed for the third time: "Wangcai, is the energy really enough?" Once there is danger, it is up to you. There was no response, it seems that Wangcai was also annoyed by Qin Han's question.

XX City Hospital, the first two words have fallen, I don't know what they are. Last time, Qin Han still chased a second-hand arms dealer named York into here, but that guy was unlucky, and before Qin Han could catch up, he was killed by the mutant creatures inside. And Qin Han didn't go deep into this hospital anymore because the target died, and evacuated directly.

Thinking about the mutated creatures in the hospital, Qin Han also had some scalp numbness, but he had to go in for the sake of the small liquid oxygen machine, but fortunately, the location of the machine was not close to the center, otherwise Qin Han, who had just followed York in and retreated last time, would not have found out.

There weren't many places to get into the hospital, and most of the doors and windows were covered in a highly toxic blue liquid. It took more than 20 minutes for Qin Han to cross the distance of 300 meters and find the entrance to enter the hospital. Years of killer career have long taught him that in the face of the unknown, no matter how careful he is, those killers who graduated with him and have better skills than him are not many survivors now.

Qin Han, who entered the hospital building, was even more careful, the two combat pistols were already in his hands, and he didn't dare to make a sound under his feet, and even the inhalation was a little vague. The mutated creatures are not mutated by the body, and the five senses change more, and a slightly louder sound will alarm them.

The sonar eyepiece on the multi-functional tactical helmet on his head had already been opened, constantly scanning any suspicious places, the surroundings were quiet and terrifying, and Qin Han could clearly hear his heartbeat.

I cursed in my heart: damn place. With his memory, Qin Han leaned towards the room where a portable small liquid oxygen generator was placed, as if he hadn't noticed that there was a black figure hanging upside down on the flowering board behind him.
