There are very few survivors here, and there are almost all black disasters around. If there is a war-level black disaster, maybe the upper levels of Donghe will use nuclear weapons to directly wipe out this area... Compared to Flika's ruthlessness, There is simply no obstacle to placing a few nuclear bombs close to no-man's land.

When he thought of this, he suddenly understood why Lao Li and the others were so busy running to crowded places. "No! It's still too unsafe here! We need to continue to reinforce it!"

Suddenly, Yu Hong felt a sense of urgency again. He stood up and pressed his hand on the wall to strengthen the Black Wind camp.

The scope of strengthening is still this cave. The area of ​​the stone castle outside is too large and it is not cost-effective. Strengthening an absolute safe zone first is the best solution to save the black mark time. Direction: strengthen the surface defense to the extent that it can withstand large-yield nuclear explosions.

After the silent recitation in his mind, a black line suddenly flowed out from the back of Yu Hong's hand, but soon, the black line ran back again. It could not be strengthened." A cold mechanical sound sounded.

Yu Hong was not surprised. The requirements were too high. He even said that this reaction should be expected. He just gave it a try first. Then, he silently strengthened it again.

Direction: Strengthen the outer layer of the safe house to protect against explosion damage.

Anyway, he doesn't have anything else that needs to be strengthened recently. Let's take a round first to see the effect. There is no rush to try Yuantu. He still has a lot of Dahui Graphite Powder on hand. Because the radiation grenade is no longer made, the consumption is also reduced. A lot. The black line flashed, but this time I didn’t refuse.

Should the Black Wind Camp be strengthened?

Countdown appears: 20:09 on the 7th.

Yu Hong looked at it, accepted it, and replied in the affirmative.

Now that the black disaster can be temporarily stabilized, in terms of explosions, it is obvious that the safe house is still far away. He must make up for this shortcoming as soon as possible.

The communicator is still repeating the news just now. It is obvious that New Aurora City plans to use Flicka as a negative example to compare how gentle and just they are. Huh.

The countdown begins.

Yu Hong breathed a sigh of relief and continued to adjust the knob to return the communicator to the chat channel with Kaijun Weisong. "Is there any other way?"

When I came over, I immediately heard Wei Song's anxious voice.

"No, your conditions are limited. If you don't have the extract as a bait to disguise a living person, I'm afraid you won't be able to withstand this time based on the current conditions alone." Zhang Kaijun said calmly. "What happened?" Yu Hong asked quickly. Look. It seems that there is something wrong with Wei Song.

"Yu Hong, you came just in time!" Wei Song raised his voice, "Suddenly, members of the camp disappeared here. At first, I thought they were killed by the black disaster when they went out, but for three consecutive days, people suddenly disappeared every day. There were not many people. , only one at a time, but no matter how we check or verify, we can't find the reason! I suspect there is a new black disaster that we have not found and recorded! Just like the back-to-back person you shared !What can you do?」

"Have you tried any method?" Yu Hong asked with his heart sinking.

"Pyroxene secret chamber, detector distribution, isolation of sunlight materials, pyroxene spray to enhance air concentration, isolation of the dead, banning and replacing speech with electronic sounds, etc., I have done everything I can!" Wei Song was obviously a little panicked. "Now. How many people have died?" Yu Hong continued to ask. He directly replaced missing with death.

"Thirteen! The most important thing is that they are all core members! They all live in the core area of ​​the underground stronghold! This means that the core area is completely unable to stop the black disaster and cannot guarantee absolute safety!" Wei Song said quickly. " Have you investigated the common denominators of all the deceased people?" Zhang Zhangjun asked.

"Yes, they all disappeared when they were alone." Wei Song replied. As a leader, she naturally cannot be a loser.

"Then let everyone work in pairs, not allowed to be alone, and continue to observe." Zhang Kaijun replied.

"I have an enhanced version of the red value detector here, which may be useful. Wei Song, if you know the address, you can come and get it." Yu Hong had no better idea. "Your place is too far away. I'll send someone there, at least. We have to run thousands of kilometers." Wei Song said helplessly.

"New Aurora City is setting up an aerial caravan, using large silent drones to transport goods, and flying along the black disaster safety cracks. It has achieved initial success. If it doesn't work, you can apply there, but I'm not sure they will I won't pay attention to you." Zhang Kaijun said solemnly. "After all, if I were them, I would give you a big one directly to completely destroy the hidden danger."

"." Wei Song was speechless. Snap.

She was offline, and since she couldn't get help online, it was naturally impossible for her to continue chatting as usual at this time.

"Yu Hong." Zhang Kaijun said calmly, "I have established a preliminary short-distance small-scale trade network here. Now we have contacted about six surviving strongholds around us. The trade method was established by me, using the connections between the black disaster rifts. A safe route to trade supplies and equipment. Do you want to join?"

"Is there a trade in materials and equipment? What do you need that I need? Are pyroxenes for sale?" Yu Hong asked. The only thing he lacks now is pyroxenes.

"Okay. I have enough inventory to last for decades. It's nothing to give you some. I need your vortex medicine tablets and some high-end equipment and weapons. Can you repair them? I'm a bioregion student here. "It's strong, but the conditions are too good in other aspects." "Yes. What's the specific price?" Yu Hong asked.

"A standard size vortex talisman board, exchange for one kilogram of standard density pyroxene..."

"Too cheap..." Yu Hong began to bargain with the other party. He was very interested in the various supplies from Kaijun. The pyroxene could also be used as a backup after the original soil could not be researched and the results were obtained. After some bickering, the two reached a consensus. .

"By the way, there are a few people here who came to my place. There is a little guy named Aisena, who claims that he can not be attacked by the Black Disaster. They want to join Gray City, do you know?" Zhang Zhangjun suddenly changed the topic, Yu Hong said in a deep voice, "It's them." Yu Hong was stunned. "Follow the rules." He said calmly.

Since the other party has already made his choice, he will not interfere.

"Of course it's according to the rules. It's a matter of safety. Even if you plead, it's useless." Zhang Kaijun smiled.

"By the way." He reminded, "According to satellite observations, there may be continuous heavy rains recently, so be prepared."

"Don't worry." Yu Hong no longer plans to go out. After the black lizard is strengthened, the radius of three kilometers is enough for him to collect various things with the black lizard. After the communication, Yu Hong took out the four pieces of black plastic left by the insect man. something.

Listening to the continuous heavy rain outside, I was thoughtful.

The next few days.

He still practiced the Thunder Kicks hard, and his inner energy quickly reached the eighth level of the third level. With the second level of inner energy that had not disappeared, he now had seventeen levels of inner energy, which was an astonishing endurance. But Whenever he relaxes, he will think of the insect-men from before and dare not even touch them. There is also the huge bird-shaped black disaster passing by in the distance, and the giant ocean black disaster that destroyed Baihe City.

Compared to these terrifying monsters, his strength is still far behind.

Seven days passed quickly, and the strengthening of the black seal was completed. The entire cave did not change much this time, except that the wooden door on the wall was thickened by a large layer, which could not be seen without looking carefully.

Lao Zhou was still making noises every day without knowing what he was doing. Except for the occasional delivery of baked dried meat and dried mushrooms, there was no one else in sight.

When Black Seal was free, Yu Hong began to experiment with strengthening the original soil of the mine. He tried simply using the original soil, but Black Seal's prompts always failed, so he began to try to add various other things to it, and combined them together. Time passed day by day, and soon, His third layer of Thunder Kick Technique and the ninth inner energy are about to be successfully condensed.

hiss…

Inside the stone castle.

Yu Hong wrote the date on the wooden board with charcoal: December 17, 2022.

The black pen tip scratched on the brown wooden board, and powder fell out.

Dong Dong Dong Dong.

Suddenly, there was a clear sound of wood knocking at the fence of the outer courtyard.

Lao Zhou, who was digging a drainage ditch in the yard, heard a sound, put down his shovel, took out a radiation grenade from under his raincoat, and carefully approached the direction of the sound.

The heavy rain outside is still falling, and there are pools of water everywhere inside and outside the camp.

After a while, Lao Zhou pushed open the public access door, shook the water off his raincoat, took it off, and walked quickly towards the stone castle.

On the second floor of the stone castle, he pushed open the wooden door and raised the bundle in his hand.

"Boss, a postman actually came! The post office is now open again!" There was a strange shock and joy on his face.

"Postman?" Yu Hong was also slightly surprised.

"Well, he is a speed-enhanced person who can run very fast. His surname is Chen, and his name is Chen Jiaze. He said that the high-risk black disaster has been basically fixed now. The cracks of the black disaster have been solidified and mapped. It can already be initially passed through, and the safety is relatively high. ." Lao Zhou was a little excited. "It's a good thing..." Yu Hong smiled. He had actually received the news from Zhang Kaijun before, but he didn't expect that not long after, the postman would deliver the goods to his door.

This surprised him somewhat.

After all, even if the bugs outside have been wiped out and haven't been revived for the time being, there will still be speeders. If you make a mistake in your escape, you're risking your life.

"But to be honest, that Chen Jiaze seems to be a little stupid..." Lao Zhou lowered his voice and shook his head slightly.

"No normal person would want to go out at this time," Yu Hong said calmly.

"Isn't this bullying those people who have strengthened their bodies?" Lao Zhou sighed.

Yu Hong said nothing and took the package.

The package is wrapped in thick waterproof plastic bags, layer after layer, and wrapped thickly.

With a scratch of his fingernail and a little force, he easily cut open the outer plastic bag completely.

Inside is a black rectangular metal box.

Opening the lid of the box, there was some foam scraps stuffed inside. Between the white plastic, there was a gray-white stone wrapped again in thick plastic. There was also a letter pressed under the stone. Yu Hong felt a little curious.

In such a harsh environment, someone would actually write to him?

He took out the stone and looked at it first. Through the transparent plastic, he hesitated for a moment and realized that the stone looked somewhat like the symbols in the pyroxene ruins. Moreover, this symbol seemed to be something he had never seen before.

Putting down the stone, he picked up the envelope again.

The envelope is light yellow, with two lines of words written in crooked handwriting on the surface: "Personally signed by Yu Hong."
Chapter completed!
