In the mountains and forests.

The mist is thick, like a veil, shrouded among the large bare trees. Poof.

Outside the camp, a black phlegm flew out and accurately hit a white rock on the ground. Hiss.

The black phlegm slowly reacted with the rocks, emitting white smoke. After a while, a small hole was corroded. The hole became deeper and deeper, and it did not stop until the black phlegm was completely consumed.

Amidst the clicking footsteps, Yu Hong, dressed in a suit, walked over and knelt down to check.

He stretched out his index finger and pierced the small hole, which was about the second knuckle. After the test, it was found that the black lizard's saliva was highly corrosive to everything. Yu Hong stood up and turned to look at Lao Lao Lai. A black lizard.

The adult black lizard is about the same size as an ordinary cat. It is completely black, and if you don't open your eyes, you would think it was a dead tree. Looking at the black lizard, Yu Hong thought about which aspect of it should be strengthened.

First of all, speed is a must, otherwise it will be meaningless if the detection capability is insufficient.

Then there's the lethality... The assassin-type scout with fast speed and high damage is the suitable sentry I need. But the physical protection is too weak and it's useless to knock him down with a gun shot... After thinking about it, Yu Hong crouched down , rubbed the black lizard’s forehead.

Speed, damage, protective physique... isn't this a comprehensive enhancement?"

He was a little helpless, so he changed his mind and quickly turned around and walked towards the camp, asking the black lizard to follow him.

After a while, he used Dahui graphite powder in the camp to draw a hidden symbol on the black lizard. Then, after thinking about it, he dragged out some unnecessary metal tools and weapons from the cave.

Stack these together with the black lizard.

Then, Yu Hong looked at the sky outside. It was pitch black.

He stretched out his hand and gently pressed it on the black lizard, and his consciousness included the pile of metals and weapons at the same time. To strengthen the black lizard, the direction: speed, damage, defensive physique.

He naturally imagined the ideal black lizard he wanted in his mind.

It should be a sentinel monster with fast speed, strong concealment, strong physique and amazing defense, and enough lethality to drag most things, making it easy to carry the loot back. Soon, the black line on the back of the hand flashed, and the black lizard was submerged. .

Do you want to strengthen the Mark: Black Lizard?"

Hei Yin's inquiry came.

At the same time, the countdown also appeared on the Black Lizard. At 09:14 on the 3rd.

Yes!" Yu Hong replied affirmatively.

Suddenly the countdown flashed and started counting quickly. He breathed a sigh of relief.

After this strengthening, the entire camp will be strengthened again, the stone fortress should be strengthened, and a closed and perfect self-circulating mechanism should be established as much as possible. Black disasters from the outside world are all kinds of strange, and there are all kinds of dangers. The greatest safety is to avoid contact as much as possible.

"Three days later, there are fewer people in the camp now, and the attraction to the Black Disaster is greatly reduced... It may be safer than before."

He let go of the black lizard and controlled it to hide in the camp. Although he didn't know what would happen if the thing being strengthened was suddenly injured and died, it was best not to try this. Three days passed in a blink of an eye.

Yu Hong always monitors the changes in the bugs outside. In the past three days, the bugs seem to have lost interest in the camp. They don't even come near here on weekdays, and there are almost no people. The mountains and forests around the camp seem to have completely entered the camp. The situation before the Black Disaster was tranquility, silence, and nothing.

There were not even any ghosts, they were all suppressed and driven away by the insect-men.

In the past three days, Yu Hong once again condensed a new inner energy, reaching the seventh root of the third level.

Although the improvement of his Thunder Legs does not allow him to fight the bugs head-on, it still gives him a sense of security because he can run fast.

At noon, the sky gradually darkened, and the fine raindrops began to fall in the cold green, hitting the mountain forest, hitting the dead leaves, and falling on the mud, making a thin sound.

Yu Hong walked out of the cave and came to the edge of the formation in the outer courtyard. Wearing the enhanced gray lizard suit, he was not worried about the rain. He was just slightly nervous to feel the black lizard outside the fence that was about to complete its enhancement. There were still six minutes left in the countdown. He simply relied on At the fence, quietly concentrate on practicing Qi.

Buzz.

Suddenly, there was a faint sound of motors coming from the driveway leading to the highway from the outer courtyard. In addition to the motors, there was also the squeezing sound of tires crushing the wet ground. Yu Hong opened his eyes suddenly and looked in that direction.

In the sight of the black lizard who was investigating outside, a familiar car was slowly approaching the camp.

That's...!?" He involuntarily straightened up and looked carefully at the direction from which the sound came. Not long after.

A black car covered with gray and black rune symbols slowly stopped at the fence outside the camp. Click.

The car door opened, and a familiar figure jumped out.

"Boss, I haven't seen you for a few days. Did you miss me?" Zhou Xueguang patted the car door with a smile on his face. "Didn't you leave? Why are you back?" Yu Hong's face remained calm.

"They are going to accompany Dr. Xu during the delivery. Lao Li is enough. What can I do if I come over?" Zhou Xueguang answered with a smile. He looked back at the misty mountain forest where it was raining.

"By the way, boss, what are you writing here? Did you know in advance that I would come back?" "I have nothing to do, observe the black disaster and collect detailed information." Yu Hong replied casually.

The return of Lao Zhou surprised him and gave him some comfort. At the same time, it also gave the deserted camp a touch of humanity again. "Go back and rest first, I have to observe for a while." Yu Hong said calmly.

"Understood!" Lao Zhou nodded, opened the fence, drove in, then closed the door and returned to the stone castle.

Yu Hong was still standing there, listening to the faint sounds coming from the stone castle behind him, and the corners of his mouth were slightly raised involuntarily. He was interrupted by Lao Zhou, and the Black Lizard immediately finished strengthening and didn't pay attention.

At this moment, he came back to his senses and sensed the black lizard imprint in his mind again.

After a few breaths, he took a step forward, climbed over the fence, and walked into the mist.

A few meters later, he stopped in front of a dead tree and looked at a brand new black lizard slowly crawling out from behind the trunk. Puff, puff, puff.

The half-human-tall black lizard looks like the world's largest Komodo dragon, much larger in size.

Its eyes were like turbid black glass beads, its body was bloated and fat, nearly two meters long, and it was covered in black scales as hard as old tree bark. Yu Hong stepped forward and reached out to knock the black lizard on the forehead.

Duh duh duh, the sound is as dull as knocking on wood.

"Come on, spit." Yu Hong pointed to a tree trunk and said in his heart. Pfft.

The black lizard spit out a mouthful of black phlegm on the spot. This time, the mass of black phlegm was three times larger than before. It directly covered the waist of the tree trunk with the thickness of an adult's waist. In the hissing sound, the tree trunk was soon corroded out. A large gap was opened, and the trees began to sway, threatening to fall and break at any time.

Not bad." Yu Hong nodded slightly, and then with a thought, he directed the new black lizard to come to a large moss-covered boulder. Bang.

The black lizard took a few steps and bumped into it.

The large boulder, which weighed at least a hundred kilograms and was about the size of a small millstone, was immediately knocked away and rolled away. It spun around a few times before stopping.

My strength has also improved a lot." Yu Hong nodded, pulled out the dagger from his back, stepped forward, and scratched the scales of the black lizard. Chi chi chi chi.

He only used the strength of an ordinary person with the tip of the knife, but he could only make white marks on the black lizard's back without being able to hurt it.

It has been synthesized with some metal elements and has good defense. Taken together, it can be considered a strong sentinel. In addition to dealing with low-level black disasters, it can also deal with some hostile entities.

The last thing is speed." He put away his knife, controlled the black lizard in his mind, and sprinted along the lane towards the highway at full speed.

"Three." Two. "One! Run!"

He also looked at the time on the detector and started counting.

The black lizard made no sound, swooped out, and disappeared into the gray mist in an instant. About half a minute later.

laugh!

The black lizard's vision suddenly stopped stably.

Yu Hong saw through the mark that it had reached the highway.

36 seconds." He estimated that the distance from the camp to the road was about a few kilometers, and it would only take half a minute to rush past the black lizard here... This speed was indeed much faster than before. In this way, the other side of the road could also be attacked. It’s included in my patrol range...and then I’ll test the limit radius.”

Yu Hong then controlled the black lizard to continue rushing towards the distance, crossing the road and crossing the slope.

Not long after, the black lizard crossed the two-kilometer limit, but this time, it did not lose contact, but still maintained contact. This refreshed Yu Hong's spirits.

Continue to control the black lizard to run far away. Soon, at three kilometers, the black lizard's vision suddenly went dark. "Lost contact."

Yu Hong let out a breath.

Three kilometers away, the control limit has increased. It seems that the improvement of the mark still depends on continuous strengthening. The stronger the mark, the stronger the comprehensive data will be. Soon, the black lizard automatically returned to within three kilometers, and the field of vision returned to As for Yu Hong.

He began to control the black lizards to return, while letting the other black lizards automatically patrol around the camp.

Now that the formation has been strengthened and the black lizard has also been strengthened, he decided to find a way to completely solve the insect problem. Let him stop staying near the camp and treat the camp as his own territory. Gray City.

The huge and burly gray city stands among the endless loess hills.

In front of the city gate, giant metal gates with a thickness of more than ten centimeters slowly rose up one after another, opening a hole for entry and exit. Outside the gate, survivors from all over the country, who had been waiting in line for a long time, swarmed up in ragged clothes, with yellow faces and skinny muscles, trying to Rush into the city.

"Everyone should line up and undergo city inspection one by one. After entering the city, read the notice on the right as soon as possible. All procedures on the notice must be strictly followed. Anyone who violates the rules will be expelled from the city."

Groups of black armed men maintaining order inside the city gate were wearing full-body bulletproof suits, holding firearms, and wearing brown goggles, with their faces completely hidden. None of them spoke, and their voices were recorded through loudspeakers. came out.

The loudspeakers were hung on both sides of the city gate, repeating continuously.

Among the armed personnel responsible for the inspection, someone was responsible for checking the information card filled in by the entrant. Suddenly, the inspector pressed a card he had just seen.

"Former postman? Baiqiu Village? Black Wind Camp??" He hesitated and looked up at the three people not far away who were undergoing the third round of inspection and frisking. Li Runshan raised his hands, as if he heard the sound, he immediately turned this way Show a sincere smile.

Eisenna was behind him, and Dr. Xu entered the tent alone with a big belly at the back for inspection. "Take these two people down, drag them out and kill them." The examiner let go of the card, waved his hand and said casually. Wow, behind him Three people from the black team immediately walked out and walked towards Li Runshan.

"Wait! We didn't do anything! What are you going to do? Why should you kill us!?" Li Runshan's expression changed instantly. This is unreasonable and illogical!!

Normal logic should be that as soon as people hear that he is a former postman, they should immediately give him special treatment. After all, postmen are elites, and they are talents wherever they are placed. But here in this gray city.!!
Chapter completed!
