The outside world is getting worse and worse, and I must prepare for a rainy day. Now that I have determined that these two are the key to ensuring my safety, then after the weapon strengthening is completed, I will focus on strengthening these two."

The formation must achieve an all-round protective effect, covering both the ground and the sky, the range must be expanded, and the buffer space must be increased. To prevent the too-fast black disaster from jumping over the formation and rushing into the core area."

"The emergence of the dragon lizard means that many of the remnants of the Black Calamity have very good strengthening effects, and the airflow crows in the formation also have good effects. So it is also important to collect such residues in the future to synthesize and strengthen them. ." After the dragon lizard has established its nest, we will then study whether it can be further strengthened. If not, we will study new synthetic creatures. There can be one or two imprints, maybe three or four. This aspect needs to be explored in the future. ." Yu Hongshuashua recorded all the key points.

Compared with practicing internal skills, I can see clearly now that directly strengthening formations and imprinted creatures will result in much greater improvements. In this increasingly dangerous environment, we must first obtain a safer living environment, and then The best strategy is to cultivate your inner strength." After confirming the enhanced formation and movable creatures such as dragon lizards, Yu Hong had a goal in mind and relaxed a lot.

Although he was still worried about Yiyi's situation, now he had done all he could and could only pray silently for her.

Yiyi itself seems to have a special physique. If she doesn't move when she is quiet, she will be ignored by the black disaster and will not be attacked. This physique gives her a higher survival rate than other people.

Coupled with the equipment and supplies he donated, as long as you are careful, don't be reckless, retreat slowly when encountering high-risk black disasters, and observe the fluctuation of the red value of the detector at any time, the problem should not be big...

Yu Hong cooked something, rested for a while, and then continued to practice. The improvement brought to him by the fifth level of Thunder Kicks was far beyond his expectations. His movement speed and explosive response speed were far beyond those of ordinary people. of strengthening.

After ensuring the running speed, the next step is to improve the protection ability... Many black disasters dare not even come into contact with them. Once they fight, they will be at a loss. Therefore, the protection of oneself must be upgraded... Then choose a course Appropriate exercises are the key. After thinking about the future, he finished practicing the exercises and refining his inner energy, then turned on the communicator.

This time the communicator seemed to have been interfered with. Instead of connecting to Kai Jun's channel immediately, bursts of hissing currents came out. I waited for a while.

Communication returns to normal.

Zhang Kaijun's rather tired voice came from the speaker.

"I'm sorry, something happened here, we are dealing with it." The voice was accompanied by bursts of gunshots. "Do you carry the communication with you?" Yu Hong asked.

"Well, it's just a portable extension." Zhang Kaijun replied, "Two hours ago, I received some unfortunate news that I need to tell you." ".You said?" Yu Hong paused and said. This world is inherently complicated. He was used to having little good news.

"The investigation team failed." Zhang Zhangjun said, "We gathered the elites from Aurora City. They took a helicopter over and found that someone had entered Black Tree Village before them. So the investigation team decided to split up and track the people in front. Trying to get in touch to get more information. The other group went straight to the ruins of Black Tree Village where the black disaster first broke out according to the original plan, but..."

"I have a question. The country must have investigated the source ruins before, so if nothing was found before, why can it be guaranteed that the investigation team can find clues now?" This is what Yu Hong has always puzzled about.

"According to information from unknown sources, the First Aurora City received the news that the black disaster originated from the black well, and the black well originated from the ruins seal. At first, no one confirmed it, so it never received support. Later, the situation worsened and nothing could be done.

"We have no other choice but to form the investigation team as a last try." Zhang Kaijun answered.

"In other words, Aurora City and you don't know whether the investigation team could be useful in the past?" Yu Hong understood.

When he heard that someone from Heishu Village had entered first, he guessed that it was probably Yiyi and An An. However, he did not rule out that there would be others.

"Yes, the specific details are all over there in New Aurora City. It is said that linguists there deciphered some of the unknown characters in the ruins and came up with part of the reasons for the outbreak of the Black Disaster. But at that time, there was no evidence to prove the validity, so

Being stranded, the situation is different now." Zhang Kaijun explained.

Yu Hong finally understood this time.

In other words, the higher-ups did not take the information about seals seriously at first. Later, other methods were tried, but too many people died. There was no other way, so they decided to follow these instructions.

Try Shenshen Naodao's method. "In addition, the people I sent to trade should be here soon. The second round will come along the black disaster crack. It won't be a big problem." Zhang Kaijun said.

"Okay." Yu Hong responded.

Bang, the communication is disconnected.

He sat at the table, was silent for a while, sighed, stood up, and continued to practice in the basement.

In the current situation, besides practicing Qigong, what else can you do?

Rather than going out, it would be the best choice for him to stay where he is and continue to strengthen the camp.

Time flies by in penance.

Just when Yu Hong was immersed in practice, the patrolling dragon outside the camp suddenly sent him a reminder through a mark.

This is what he ordered. If you encounter any movement other than the black disaster, report to him in time.

Yu Hong paused his Qi training, looked outside through the dragon lizard's vision, quickly put on the enhanced suit, left the cave, and came to the fence of the outer courtyard.

It was already dark gray time.

Outside the fence, stood a short man covered in a thick black cloak.

He lowered his head, wearing a thick rusty helmet around his neck, and coughs with phlegm sounds came from the breathing valve from time to time.

Compared to Yu Hong, he is only as tall as his chest, with gray-white pyroxene runes and hidden runes printed all over his body.

The hidden runes were obviously ineffective, and the lines that did not inject inner energy were immediately ineffective in Yu Hong's eyes.

"I am Shu Cheng. I have been entrusted by Commander Zhang from Gray City to come to the Black Wind Camp to trade the resources needed." The man lowered his head and his voice was humble and calm. There was no trace of the panic and fear of the escapees and survivors outside.

.

"You ran such a long way alone?" Yu Hong was a little surprised. He raised his eyes and looked at the thick fog behind the other party. There was no one behind him. The farther positions were submerged in the fog and could not be seen clearly.

"More than that, there are three of us. In order to safely transport resources and goods, we have all undergone a certain degree of body modification. Please forgive me, Mr. Yu." The man who called himself Shu Cheng continued.

"Renovation?"

"Yes... due to the emergence of high-risk black disasters, the design of a single-layer pyroxene chamber cannot be effective. Therefore, the expert team of Gray City gave a three-layer plan to reduce the aura of living people, increase the number of exhibitions in the pyroxene chamber, and assimilate and conceal the aura. Protection advice." Shu Cheng said with a smile.

"Reduce the breath of living people...you..." Yu Hong's eyes narrowed, and before he could finish speaking, he was stunned by the opponent's right calf that was held up.

Shu Cheng's right leg is not a flesh and blood body, but a prosthetic leg.

Immediately afterwards, the other party picked up his left leg, and his left hand turned out to be a black metal prosthesis.

"In addition, the raw meat on my body has been reduced to the limit as much as possible."

Shu Cheng took off the hood of his cloak, revealing his bare ears and nose.

Both his ears and nose were cut off!

"According to research, the Black Disaster targets fresh flesh and blood and is a special group that carries out hunting and erosion operations. Therefore, as long as the total amount of fresh flesh and blood on one's body is reduced as much as possible, one's sense of existence can be greatly reduced."

"Yu Hong was speechless.

"In addition, all my skin has been tattooed with pyroxene powder. There are three layers in total: one layer of skin, one layer of inner armor, and one layer of coat. I need to protect it from leaks when walking, which is quite hard." Shu Cheng Smiling. "So what about assimilation to cover up the aura?" Yu Hong asked. "How did you do it?"

"Ah, this..." Shu Cheng let out a weird low laugh. He put on his hood again and lowered his head, like a hunchbacked dwarf.

"According to laboratory test calculations, some of the radiation residues of low-level black disasters are implanted in our bodies. As a researcher, you should also know that sometimes low-level black disasters are not necessarily worse than high-level black disasters. It is just that some are more lethal and The range is not large, and the expressiveness is a bit poor. So..."

He paused and continued.

".We will implant this kind of black disaster remnant into the body and let it emit a slightly higher red value radiation than the environment. This will confuse the breath of living people... Of course, the price of this is that our life span will be shortened. It will take about five years. But it doesn’t matter... Even so, there are still many people willing to undergo this surgery..."

Yu Hong was speechless.

He originally thought that some of the survivors he met before had done everything to the extreme in order to survive, but now, seeing Shu Cheng coming from Huicheng, he knew what it meant to go to the extreme. "Okay, let's proceed as quickly as possible. Resource exchange, right? Some of the things you need have been brought here." Shu Cheng said.

"Okay!" Yu Hong turned back and carried out the vortex talisman board from the cave. This thing is not like a radiation grenade. It requires black seal reinforcement to complete the design and processing. This thing can be mass-produced with internal energy, so it is not a treasure.

Prepare two hundred vortex talisman boards, paired with a radiation grenade, and take them to the opponent to study the structural design. After that, Huicheng will surely be able to transform the vortex talisman boards into radiation grenades. This will also increase the number of weapons there. defensive strength.

The main thing Yu Hong trades here is pyroxene powder. After the pyroxene mine disappeared, pyroxene powder became a scarce resource.

Two hundred vortex talisman boards plus a grenade consume less than one kilogram of pyroxene powder, and the pyroxene powder in exchange is two hundred kilograms. This is far enough for Yu Hong to use for a long time.

In addition to pyroxene powder, these items were also exchanged for a bucket of Sunshine No. 7 special material paint.

"Because pyroxene powder will be offset by the red value in the air under the current environment, I dare not bring too much. Please understand. This is the first transaction. Here comes a simple monitoring system for you, equipped with an ordinary power plug It's ready to use." Shu Cheng took out a white packaging box from the pocket on his back.

The packaging box is the size of a magazine and as thick as a dictionary.
