Xue Ningning forced Ou Li to leave.

They brought enhanced detectors sponsored by Yu Hong to determine whether the departure time was still in gray time.

The goal of this exploration is to find out why the surrounding environment has changed so much. At the same time, it is necessary to determine whether the Black Disaster Rift can still guarantee safety.

At dawn the next day, the two women took the detectors lent to them by Yu Hong and went out.

They walked out of the camp wearing pyroxene blankets with swirling runes and indifferent expressions on their faces.

Xue Ningning had made up her mind, but Ou Li was obviously too scared and was still a little confused.

She was forced out by Xue Ningning.

But Yu Hong still stayed in the camp, regenerating new black lizards, and the surrounding black lizards died in one breath, which caused great inconvenience for him to explore the surrounding area.

So when Xue Ningning and the two went out to investigate every day, he stayed in the cave, replenishing the black lizards and strengthening the new formation.

Inside the cave, under bright white lights.

The warm air temperature brought by the cooling pipes keeps the entire cave stronghold at a constant room temperature of more than ten degrees.

The heavy cave door is densely engraved with various combinations of runes.

Each rune pattern has an effective range. Taking advantage of this, multiple runes are combined together to form a rather complex rune pattern. This rune pattern has the concealment effect of the pyroxene chamber and comes with storage. Negative radiation can continuously release weak negative radiation of 1.

This is a structure similar to a release device that he created by combining the deceleration runes and the traction runes.

He didn't rely on the black seal, it was just his own test results.

And this kind of achievement has been updated throughout the cave.

"It is still necessary for the most primitive version of the formation to release the negative radiation that makes Black Disaster disgusted. To maintain this disgust, but not to prevent the formation runes from accumulating radiation, there is a certain balance that needs to be grasped."

Yu Hong sat on the wooden chair and leaned back on the chair, feeling the defense system at this time.

The inner wall of the cave includes the gate, which is a core layer of defense.

Then there is the outer layer of the inner courtyard and outer courtyard formation, which is modified from the wind and fire spirit slaying formation strengthened by the black seal.

The black lizards that were still in the outer layer are currently recovering.

With three layers of defense, Black Lizard is still too weak...

Yu Hong sighed and looked around the cave.

The two-story cave safe house is still in a very safe position. Multiple formation protections prevent outside black disasters from even discovering the existence of the cave safe house.

The physical strength of the inner wall of the cave, which has been strengthened many times, has exceeded his imagination. At least the bullets that have been tried cannot make a deep hole. The hardness has at least increased several times.

However, when I think of those clusters of human hands and shadows... such protection is probably...

After resting for a while, he stood up without going out. He first checked the mine culture soil that Black Seal was strengthening.

This is his fourth attempt to use the Black Seal.

The purpose is to cultivate and produce pyroxene mine as soon as possible. Now after the demise of the mine, radiation grenades cannot be replenished. Dahui graphite powder is related to many defense systems of the camp. Once pyroxene cannot be replenished for a long time, the trading team will be

The black disaster prevented him from getting over, so he could only try to produce pyroxene on his own.

In the basement.

The original soil that was counting down was still gray and black, with no change except that it was a little dry. Yu Hong looked at the remaining time, which was 12 minutes.

Soon.

He picked up the stone that he had strengthened three times before.

The three stone blocks are about the size of a fingernail. They are all gray and white, similar to pyroxene. The number 123 is written on the surface in charcoal.

Yu Hong took the detector and checked it again. No. 1: 11.241

No. 2: 9.245 No. 3: 5.117

The three strengthened white stones all emit red value radiation. Although they are turning to negative values ​​step by step, they are still far away from the pyroxene for the time being. Yu Hong waited for a while until the fourth countdown ended.

laugh.

The original soil blurred for a moment, and suddenly turned into a white stone the size of a fingernail. He quickly picked it up and put it against the detector for inspection.

'0.214'

Seeing this value, Yu Hong finally showed a trace of relaxation on his face.

It seems that this direction is correct. After adding the vortex rune pattern, it does have an effect."

When he strengthened, he obviously followed the function of pyroxene as the direction of strengthening, but the synthesized stone was not pyroxene.

Theoretically, pyroxene ore will automatically emit negative radiation, but the white stone I synthesized... still seems to be missing something... The vortex runes can only absorb red values ​​and will not emit negative radiation." Yu Hong

After thinking about it, I took out the test data recorded previously.

He was not sure whether the white stone he made could be used. But comparing the data before and after, he found that the radiation of the three white stones all showed a decrease in the red value to varying degrees. The decrease in the red value meant that it was approaching a negative value.

In this world where the radiation in the environment has a red value of thirty or forty units, although the red value in the cave is weak, it has reached nearly ten units recently. Changes in the three white stones mean there is something going on.

Wait, could it be that the difference lies in...time?" Suddenly, he thought of something.

The white stone he made does have the effect of suppressing the surrounding red value, but the effect is very weak, which is very different from the original pyroxene. Holding the three white stones, Yu Hong thought quickly in his mind.

Pyroxene ore has been soaked in red radiation, so why can it still exist instead of automatically dissolving like ice cubes in hot water?"

Obviously, pyroxene ore may also have some special replenishment channel. And pyroxene should also have the ability to store negative radiation. Otherwise, it cannot explain the huge gap between ordinary pyroxene and pyroxene marrow. Think of this.

Yu Hong seems to have determined the direction of his strengthening.

It seems that there is no problem with strengthening the black mark. The effect of the white stone I strengthened is so weak. The key is that it lacks a long-term infiltration and charging process. There must be a channel for continuously charging negative radiation in the previous mine. And as time goes by, the pyroxene ore is gradually filled."

Thinking of this, he quickly found tools and used Dahui graphite powder to draw vortex patterns driven by the inner energy on the three white stones. Then he waited for the results.

After doing this, the black mark is also free. The black lizard does not need to occupy the black mark to revive.

Yu Hong came back to the first floor and picked up a piece of the talisman array he was trying to assemble from the wooden table. There was a two-character scrawled on the wooden board, which was Chinese characters. It represented the second formation.

Using the newly obtained traction runes as the main body and the vortex runes as the core, they were added to the wind and fire spirit-slaying formation outside as a second auxiliary formation to strengthen the total radiation reserve of the main formation. This idea was not a big problem. He recalled The scene before when I encountered a large number of gray hands.

The formation's lethality was still sufficient, but the total amount of radiation was too small, and it was instantly consumed by the Black Disaster's numerical advantage. Picking up the second formation plank, Yu Hong walked out of the cave, walked out of the passage, and stood still in the empty inner courtyard. .

Under the white light, it was still dark outside the fence of the outer courtyard.

It was now gray, and Xue Ningning and the two were still investigating the situation. The camp was deserted. Squatting down, Yu Hong put down the board with one hand and pressed it on the ground.

Strengthen the Black Wind Protection Array, direction..." Yu Hong imagined in his mind the area, range, and intensity covered by the second array, and connected and superimposed it on the edge of the main array. Soon, his own design got the approval of the black seal It is basically recognized and considered to have the basic effect of supplementing the total radiation reserve.

So it was further strengthened.

Do you want to strengthen the black wind protection array? Yes.

A countdown appeared, the time was: 7:53 on the 1st. Yu Hong stood up and breathed a sigh of relief.

Now all that is left is to wait, wait for the strengthening to be completed, and see the effect. If possible, he plans to strengthen a few more auxiliary formations to connect to the main formation as a backup energy package. After doing this,

He continued to the inner courtyard and began to expand the size of the breeding house cave right next to the edge of the cave. This is also called mining for short.

Because the stone castle was built before, this temporary cave breeding house was stranded.

This time, he plans to expand the camp cabin again and create a temporary residence for outsiders that can at least be sheltered from wind and rain and located inside the formation. Such a residence can be used for reserve members between visitors and full members.

The outer courtyard is still too dangerous. Whenever the formation confronts Black Disaster, it will affect reserve members like Xue Ningning.

After digging for a while, subtle footsteps were heard in the outer courtyard. In the pouring rain, two figures wearing thick pyroxene cloaks came in through the fence entrance in the rain.

They quickly entered a wooden shed in the outer courtyard, shook off the rainwater, put down some things they found, and then approached Yu Hong.

Soon, the two entered the area with the brightest lights, revealing two young faces wearing breathing valves.

It was Xue Ningning and Ou Li.

"Mr. Yu, this time we have completed the verification." Xue Ningning walked closer and said quickly. "The black disaster fissures have not changed. The changes that occurred during the black time, as well as the new black disaster, will not affect the original distribution of the black disaster at other times at all. They seem to exist in two different areas and different spaces without interfering with each other."

"Yes, when we go out during the gray hour, we will encounter the same location and area as before. But when it comes to the dark hour, these places will be replaced by a new batch of black disasters. The danger is far greater than before." Ou Li said in a deep voice

"In other words, dark hours will turn originally safe places into extremely dangerous areas? So at other times, can originally dangerous places also become safer areas during dark hours?" Yu Hong put down his hand. He asked in a deep voice, "I don't know about this. In addition, we also discovered the wooden bridge behind the camp that you mentioned only appears when the light is found, but we did not have any confusion in distance or direction. ." Xue Ningning continued.

"How did you do it?" Yu Hong asked curiously.

"Using a flashlight to shine from a long distance, you can vaguely see the existence of the wooden bridge. Maybe it is too far away and there is no black disaster attack." Xue Ningning answered.

After knowing the specific location of the black disaster, their safety was greatly guaranteed.

"We have confirmed that there is no problem with the Black Disaster Rift. Next, we plan to investigate the reasons for the change in the intensity of the Black Disaster." Xue Ningning continued.

"What are you going to do?" Yu Hong asked

"According to the previous information, the place where the black disaster first broke out must have traces of why it broke out in the first place, and the Mesha family definitely has the secret. We plan to go to the place of origin to investigate first, and then track the Mesha family."

Listening to Xue Ningning's words, Yu Hongguang felt that it was a fantasy. In such a dangerous outside world, they were the only two enhanced people, not full-body enhanced people. Their strength was not much stronger than ordinary people in the face of the black disaster, but they actually wanted to run away. So far away, trace and investigate the source

He fell silent.

Because he felt that the other two would definitely die.

After calming down for a few breaths.

"Just go alone." Yu Hong said. "You will die."

"Someone has to do it. If I can investigate useful information before I die, it can also reduce the burden on those who come after me." Xue Ningning's eyes were calm. "In this way, at least my death will not be meaningless."

"But I... don't want to..." Ou Li beside him couldn't help but his face twisted, but he didn't dare to speak too loudly, so Xue Ningning ignored him.

Yu Hong thought for a moment.

"Wait a mininute.

He quickly turned around and entered the cave.

Open the communicator.

"Kaifeng Jun, are you there?"
