Those who dare to talk to Li Wen like this are probably far away except for Xinghe.

"Chief, I'm not giving up, I'm just coming back to prepare, judging from the current situation, I have a good chance of success."

Li Wen frowned and was silent, he ignored Gao Yuan, after thinking for a long time, he looked at Shi Lei and said, "You are the commander, you say, should Gao Yuan continue the mission?" I would like to remind you first, don't be worried, tell the truth. ”

Shi Lei said without hesitation: "Report to the chief, I think the mission can be continued, because since Gao Yuan can go in and come back safely, it has already explained the problem." ”

Gao Yuan also said urgently: "Yes, chief, since I went in and encountered a large number of zombies, I can still come out safely, which shows that I can, why give up halfway." ”

I don't blame Li Wen for being careful, the problem has to be looked at from two aspects.

A crucial bridge in communication with aliens, or an emotional bond, or a mobile vaccine bank for human beings, a genetic treasure.

On one side is the key material for controlled nuclear fusion.

You say it's important over there?

In fact, if you really want to say something important, Gao Yuan is much more important than nuclear materials, because if you can't get nuclear materials, you can still find a way, and you really can't clear the way with tactical nuclear weapons, and you can get the nuclear materials back.

But there is only one Gao Yuan, if he dies, no one can say what the subsequent chain reaction will be.

However, the attraction of being able to get nuclear materials back as soon as possible is too great under the premise of ensuring high security.

Li Wen finally nodded, and he said in a deep voice: "Okay, I trust your judgment, so you can just bring up what else you need." ”

"Yes!"

Gao Yuan was very happy, and then he immediately said: "I need to make a shield, carry more energy bars, and need some equipment that can make a sound to attract zombies away, and I don't need anything else." ”

What Gao Yuan wanted was actually very simple, so the High Command didn't need to prepare much, and it would be able to meet his needs right away.

This shield requires a little bit of thought, is it a ready-made explosion-proof shield, or is it a separate special one?

After discussion, and after a study and judgment of Gao Yuan's expected use scenarios, those military experts decided to make a special shield for Gao Yuan.

It was as light as possible and sturdy enough, and then the shape was quickly decided.

Instead of a circle, a rectangle is used, but the length is relatively short, and when Gao Yuan is raised, it is enough to cover his upper body, and the legs do not need to be protected.

Then the shield should be made into a triangle as much as possible, that is, the middle of the shield is protruding forward, and the angle is also very large, because the main purpose of the high shield is not to protect itself, but as a roadblock, the flat shield can knock the zombie away, but in this case, it is better to push the zombie to both sides to save effort.

The shield was quickly made, a steel frame covered with engineering plastic, like a piece of paper folded in half and then unfolded at an angle.

It's actually still very simple, but it's easy to use.

After repeated trials and tests, he confirmed that the shield met his requirements, and the biggest purpose of Gao Yuan's return was completed.

Then the next thing to do is simpler, that is, rest, in addition to eating well, a good sleep is also a must.

After enough food and sleep, it was impossible for Gao Yuan to wait for two more days before moving again, and that night, the group of them again came to the position where they set off during the day.

There was no zombie activity around, some moonlight, but it was very dim, and spring was the windiest season.

The moon is dark and the wind is high and the night kills.

"Turn on your night vision."

Gao Yuan turned on the night vision device, he glanced around, and then he was extremely surprised and said, "Wow, it's so clear, and it's still colored." ”

Except for some color differences, the night vision device used by Gao Yuan looks almost the same as in the daytime, very clear and very bright.

"Test the thermal imaging mode."

Gao Yuan changed the helmet-type night vision device to the thermal imaging mode, and then there was no color in his eyepieces, but Shi Lei, who was squatting opposite him, looked red.

"Red-hot mode, normal thermal imaging."

Gao Yuan lifted the eyepiece of the dual-mode helmet-type night vision device from his eyes, and Shi Lei said in a low voice: "What, aren't you used to carrying activities?" ”

"It's a bit hard to get used to."

"You have to adapt as quickly as possible, and don't take off your night vision devices again if there are no special circumstances."

Gao Yuan put the eyepiece back in front of him and whispered, "Okay, then I'm leaving." ”

Shi Lei said in a low voice: "No, you are moving in place, when do you adapt to moving with night vision devices and then set off, this is an order." ”

Don't go against the experts, no matter whether Gao Yuan feels it is necessary or not, since Shi Lei said so, then he will definitely do it.

"Alert."

The others spread out their guards, Gao Yuan alone wore night vision devices and paced back and forth in the circle formed by others, and then he also ran and jumped from time to time.

At first, he could clearly feel the presence of the helmet and the weight of the night vision device, but after walking back and forth in place for a while, he didn't seem to feel the presence of the night vision device.

Seeing Gao Yuan's activities becoming more and more free, Shi Lei said in a low voice: "How is it?" Do you feel dizzy and nauseous? ”

"No, not at all."

"Very good, you can go, be careful, it's still the same sentence, I'd rather give up the mission than come back safely."

"Understood!"

This time, Gao Yuan directly pulled out the knife, and then he raised the shield diagonally in front of him, which was also the height of his chin, and ran forward.

One of the benefits of the night is that you don't have to worry about being found by zombies far away.

Takato took a different route and headed towards the city, his speed was fast, but barely sound, thanks to his shoes and pants.

The shoes are very strong, directly using Kevlar fiber to give him special shoes, the sole is a new type of polymer, originally made of aircraft tires, very soft and elastic very good, but the most important requirement of the sole is not to break under the high and strong pedaling.

The weight on his body is dozens of catties, but this weight is almost not noticeable to Gao Yuan.

The journey was very smooth, Gao Yuan took the initiative to approach after finding the zombie, and tested it very carefully, but when the distance reached thirty meters, the zombie finally discovered his existence.

Taking advantage of the fact that the zombies had not yet gathered in large numbers, Gao Yuan cut down the first zombie, and then found the zombie to test, and after being discovered, the zombie was silently hacked to death again, and after repeating this six times, Gao Yuan got a rough data.

It was found at 41 meters at the farthest and 17 meters at the closest, a distance that is greatly reduced compared to daytime.

After the test, Gao Yuan's confidence increased greatly, and he felt that tonight was the chance to win.
