Anyone who dares to talk to Li Wen like this is probably someone other than Xinghe.

"Chief, I'm not giving up, I'm just coming back to prepare. Judging from the current situation, I'm very hopeful of succeeding."

Li Wen frowned and said nothing. He ignored Gao Yuan. After thinking for a long time, he looked at Shi Lei and said, "You are the commander. Do you think Gao Yuan should be allowed to continue the mission? I want to remind you first.

, don’t have any worries, just tell the truth.”

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

Gao Yuan also said anxiously: "Yes, Chief, since I went in and encountered a large number of zombies and still came out safely, it shows that I can do it. Why should I give up halfway?"

Don’t blame Li Wen for being cautious. The problem must be viewed from two aspects.

It is an extremely critical bridge in communication with aliens, or an emotional bond, and it is also a mobile vaccine library and genetic treasure for humans.

On one side are key materials for controllable nuclear fusion.

Do you think that side is important?

In fact, if it is really important, the high distance is much more important than the nuclear materials, because if the nuclear materials cannot be obtained, we can find another way. If it is not possible, we can use tactical nuclear weapons to clear the area, and we can still get the nuclear materials back.

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

However, the attraction of being able to retrieve nuclear materials as soon as possible while ensuring high safety is too great.

Li Wen finally nodded and said in a deep voice: "Okay, I trust your judgment, so just ask for anything else you need."

"yes!"

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

What Gao Yuan wanted was actually very simple, so the high command did not need to make any preparations and could meet his needs immediately.

This shield requires a little thought. Should I use a ready-made explosion-proof shield, or should I make it separately?

After discussion and a review of Gao Yuan's intended use scenarios, the military industry experts decided to make a special shield for Gao Yuan.

It had to be strong enough while still being as light as possible, and then the shape was quickly determined.

Instead of using a circle, use a rectangular shape, but the length is relatively short. When raised high, it is enough to cover his upper body, and there is no need to consider protection for the legs.

Then the shield should be made into a triangle-like shape as much as possible, that is, the middle of the shield protrudes forward, and the angle is very large, because the main purpose of Gaoyuan's shield is not to protect oneself, but to push away roadblocks and flat plates.

The shield can knock zombies away, but in this case, it is less labor-intensive than pushing zombies to both sides.

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

In fact, it is still very crude, but it is easy to use.

After repeated tests several times to confirm that the shield met his requirements, Gao Yuan's biggest goal of returning was completed.

Then the next thing to do is to do something simpler, that is, rest. In addition to eating a full meal, getting a good sleep is also a must.

After eating and sleeping well, Gao Yuan could not wait another two days before taking action again. That night, the group of them once again arrived at the location where they set out during the day.

There were no zombie activities around, there was some moonlight, but it was very dim, and spring was also the windiest season.

It’s a murderous night with a dark moon and high wind.

"Turn on night vision."

Gao Yuan turned on the night vision device. He glanced around, and then he said in great surprise: "Wow, it's so clear, and it's also in color."

Except for some chromatic aberration, the night vision device used by Gaoyuan looks almost the same as during the day, very clear and very bright.

"Test thermal imaging mode."

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

"Red heat mode, thermal imaging is normal."

Gao Yuan lifted the eyepiece of the dual-mode helmet-mounted night vision device from his eyes, and Shi Lei whispered: "What, are you not used to carrying it around?"

"It's really a bit unaccustomed to it."

"You must adapt as soon as possible. If there are no special circumstances, do not take off the night vision goggles again."

Gao Yuan put the eyepiece back in front of his eyes and whispered: "Okay, then I'll set off."

Shi Lei whispered: "No, you just stay where you are. When you get used to wearing night vision goggles, you can set off again. This is an order."

Don't go against the experts. Regardless of whether Gao Yuan thinks it's necessary or not, since Shi Lei said so, he will definitely do it.

"alert."

The others were on alert, and Gao Yuan was pacing back and forth in the circle surrounded by others wearing night vision goggles. Then he would run and jump from time to time.

At first, he could clearly feel the presence of the helmet and the weight of the night vision goggles, but after Gao Yuan walked back and forth for a while, he seemed to no longer feel the presence of the night vision goggles.

Seeing Gao Yuan move more and more freely, Shi Lei whispered: "How are you? Do you feel dizzy and nauseated?"

"No, not at all."

"Very good, it's time to set off. Be careful. Again, I would rather give up the mission than come back safely."

"clear!"

This time Gao Yuan directly pulled out the sword, then he held the shield diagonally in front of him, reaching the height of his chin, and ran forward.

One advantage of the night is that you don’t have to worry about being discovered by zombies when you are far away.

Gao Yuan took a different route than during the day and ran towards the city. His speed was very fast, but he made almost no sound, thanks to his shoes and pants.

The shoes are very strong. They were specially made for him using Kevlar fiber. The soles are a new type of polymer. They were originally used to make aircraft tires. They are very soft and elastic. However, the most important requirement for the soles is that they will not be exposed to strong force at high altitudes.

It broke under the pedal.

There were dozens of kilograms of weight on his body, but Gao Yuan was barely aware of this weight.

The march was going smoothly. After discovering the zombie, Gao Yuan took the initiative to approach and tested it very carefully. However, the zombie finally discovered his existence when the distance reached 30 meters.

Taking advantage of the fact that the zombies had not yet gathered in large numbers, Gao Yuan could test it to his heart's content. Gao Yuan chopped down the first zombie, and then found another zombie to test. After being discovered, he hacked the zombie to death silently again. After repeating this six times, Gao Yuan

A rough figure was obtained.

The furthest distance was 41 meters when it was discovered, and the closest distance was 17 meters. Compared with the daytime, this distance was greatly shortened.
