Natsujo and Akagaki walked together towards the interior of the Stone Castle, which was filled with houses of all kinds, from the Stone Age to the Middle Ages to the modern era, full of elements from various eras, and in the center of them, there was a towering futuristic style stone building, which seemed to be more tightly knit than the stone houses on the periphery, and it was not known what was wrapped in it.

"Xia Cheng, these buildings seem to be distributed regularly. "After walking for dozens of minutes, I walked from the simple stone houses to the medieval castles and houses.

"The further you go out, the more rudimentary these houses become, and the more shabby the place, the weaker the smell of danger. Xia Cheng stared at the tall towers in the distance ahead, which were beyond the age of human technology, and almost all of them were unattainable buildings as far as the eye could see.

"Dangerous aura?" Akagaki asked, looking around puzzled.

"There are nuclear-class creatures living here, but they don't congregate in the houses outside, but look for a wider place to live, and if you guess correctly, the size of those monsters has evolved to another level with the living environment. Xia Cheng glanced back at the cliff behind him, which was already covered by a layer of mist, but he could vaguely see a few people busy on it, "It looks like it will be a long time before they come down." ”

"So what do we do now?"

Xia Cheng glanced at these buildings and said lightly: "Go and search what is in these houses, and by the way, find out what is the difference between this city and the forest above, since we came here first, we must master the environment and rules of this place before them." ”

"Well, got it, I'll see you in the square over here later. Akagaki pointed to the square on the left, Xia Cheng said just now that the square he saw on the cliff was it, and it would take about forty minutes to walk over, and I was afraid that it would be dark to get here to see the progress of Irako.

The two parted ways and began to explore the surrounding houses.

"Click. "The door is heavy, and since it's made of stone, it takes twice as much effort to push it open as a wooden door.

"Is everything made of stone?" Akagaki picked up a teacup on the living room table, accustomed to glass or ceramics, the rough feel was uncomfortable.

Everything in this house seemed to be cursed by Medusa, except for the gray of the stone, there was no second color, and after a long time, the whole person's nerves would be depressed, and the heavy air made the breathing not so sharp, inhaling and exhaling harder than usual.

There is no food, no water, this is a dead city completely cut off from living things, even if there are monsters, it is impossible to adapt to the environment of this place, and the nuclear-level creatures that do not need to eat and drink have never been seen so far.

Thinking that there was no water source here, Akagaki subconsciously licked her lips, the water on her body had already drunk a fine when she was on it, she thought that there would be a new water source here, but she didn't expect it to be such a lifeless city.

It was getting late, and the distant sound of Irako shouting could be heard from the distance of the city, and the blue dragon scales in their hands were shining, dotting the poor city in the dark night, and only Akagaki was sitting on the stones of the square waiting for them to approach, Xia Cheng had been wandering around here all afternoon, and had not returned until now.

"Hmm, why are you the only one here, Xia Cheng?" Irako tried to illuminate the surroundings with the light of the blue dragon scales.

"She's going to check the house here, but why hasn't she come back after so long......" Akagaki also began to worry, but with Xia Cheng's ability, there was nothing that could put her in danger, "We can't stay here for too long, we must hurry back to the forest." ”

"Why?" asked Xiaozhu curiously.

"The city has no water and no food, and there is only one way to stay. ”

"Hmm, don't you have any water?" Irako smiled as she handed her jug to Akagaki, "When we came down just now, we found a water source near the stone wall, and the water was flowing down from the forest above. ”

"Stone wall?" Akagaki took a sip of water, frowned and thought: "If there is really no water in the city, then our range of activities will be limited to the vicinity of the stone wall, and the problem of water will not be mentioned for the time being, and the food ...... it."

"As for the food, there is as much as you need here. While a few people were thinking about survival strategies, Xia Cheng's voice came from the dark alley on the side, carrying two small nuclear-grade creatures in her hands, species that had never been seen before.

"Xia Cheng, where did these things come from?" asked Shang Yue, looking at the nuclear-grade creature in Xia Cheng's hand.

"I wasted a lot of time trying to catch the ones that were found in the house. ”

"But...... We don't have the materials to make a fire, so we can't eat raw meat, we'll get sick. Irako poked the monster's corpse, and the meat seemed fine, but as Akagaki said, the city had no water, no food, nothing but stones, and similarly, stones could not be used to make fire.

Xia Cheng pushed the handle of the knife and opened the door behind Akagaki, only to see that there was an incredible fire inside!

"When I was passing by the house just now, I noticed that their fireplaces burn on their own, and the fire is real, and it can probably bake these things. ”

Several people crowded into the house and found that there was really a fire burning in the empty living room, and there was clearly nothing in the fireplace.

"How did these fires start?" Xiaozhu squatted in front of the fireplace, looking at the flames burning out of thin air inside.

"I don't know, anyway, it can be used. Xia Cheng threw the food into the fire and let the fire burn away the fluff from the outside.

"This is our place tonight, and tomorrow the earliest awakened person will go to the water source of the stone wall to fill up everyone's reserves, and in the limited time he must find out the details of the city. Xia Cheng put the kettle in his backpack on the table, they had enough water for three days, and in order to stay on the way back, they had to reach the center of the city, the towers and buildings, in a day or so.

The next day, with plenty of water, Xia Cheng and his party began to march towards the interior of Stone City.

Towards noon, the last old house of the Middle Ages is gone, and it is surrounded by friendly modern buildings, but these are only a flash in the pang, only reminiscent of the previous life.

"Something nearby was watching us. Xia Cheng suddenly said coldly.

"Finally, there is a fight, Xia Cheng, let's go find them!"

"Miss Irako, we must avoid fighting, otherwise the water resources will not allow us to reach our destination. "Akagaki is well aware of the situation, and although he knows that his team is being targeted by monsters, he can't just take them out.

"Well, fix them. Xia Cheng's answer surprised Akagaki, and she stared at Xia Cheng with wide eyes, not knowing why she would agree with Irakona's crazy move!

"Xia Cheng, why?"

"Those monsters will gather more and more, and if you don't want to get in trouble, you can kill them before they attract more nuclear-class creatures. Xia Cheng's sharp gaze glanced behind him sharply, and the knife in his hand was instantly unsheathed, and he actually cut off the monster's head with a knife from a distance of more than ten meters!" "There are still five left, they must be dealt with." ”

"Leave it to me!" Irako finally got her wish, and the black twin blades quickly left deep and shallow blood on the body of the nuclear-level creature, and with the exquisite leg technique, it was as if she was dancing.

These monsters weren't very strong, but everyone was slightly aware of the anomalous sensation from the previous battle.

These monsters have gotten bigger.

In order to adapt to the forest environment, they had to maintain their size and be able to travel in front of trees, but now they live in cities, and there are no cluttered trees, and their size is gradually lifted and they are becoming larger and more threatening.

However, the bigger the monster, the slower the action tends to be compared to other creatures, and the so-called gain must be lost, this kind of truth is completely feasible even in another world.

"Xia Cheng, there's another group of nuclear-level creatures coming over to the west!" Akagaki, who was fighting with nuclear-level creatures on the rooftop, suddenly shouted, "There are too many of them, we must not fight them!"

Xia Cheng had already used his own perception to perceive the herd of beasts in the west, and they shook the earth, fearing that there were many of them.

"Go to that building!" Xia Cheng glanced around, these monsters were so large that it was impossible for humans to enter the stairs, and some monsters that could get into the building with their short bodies were not to be feared at all.

A few people quickly ran into the stairway and climbed up the stairs for about four or five floors, making sure that their own scent would not be left within the range that a nuclear-grade creature could detect before stopping.

"Now the city is completely overrun by nuclear-class creatures, no, it's better that we've intruded into their territory. Shangyue said as he looked at a large area of nuclear-grade creatures in Wuyang below. Those monsters have been together for a long time, and they start to fight with each other, and the small creatures will be wiped out by the large monsters in an instant, and the large monsters will be slowly eaten away by a group of vigorous nuclear-level creatures.

"Go into the inner room. Xia Cheng noticed a few blue dragons hovering in the air, they were also several times larger than they had seen before, flying in the sky as if they were real dragons!

"Xia Cheng, the monsters here have all evolved to this extent......" Irako walked to a window, looked at the towers and buildings in the distance and asked, "What will become of the nuclear-grade creatures over there?"

No one answered this question, everything is unknown, only that from here, the further you go, the more difficult it becomes, even if there are casualties, it is normal, but looking at the distribution of this kind of nuclear-level creatures, there should be no sun-level dangerous species in this depth.
