After a while, the two came to the highest point of Flint Mountain, Luo Lihua looked for the location of the kitchen, and saw a reflective thing, she walked over quickly, only to see that on the two raised stones, someone had a transparent glass in the middle, and the bottom of the glass was hollowed out at both ends.

"Brother Gensheng, look here, it's the place where there is light in the kitchen, right?" The first time she saw the transparent glass, Luo Lihua felt a little strange, and carefully reached out and stroked it, the smooth glass was cool, and Luo Lihua immediately retracted her hand.

"What's wrong?" Luo Gensheng looked at her like that and asked.

"It's cold, but it's flat, do you know what it's called?" Luo Lihua looked at Luo Gensheng and asked. Luo Gensheng looked at the glass, and remembered in his mind that what he had seen in the city was called "glass" by others. ”

"This is glass, which can be waterproof and transparent, the people who live here are so smart, so that the smoke from the kitchen comes out, and the light is seen inside, which is really a double win." Luo Gensheng sighed at the ingenuity of the immortals.

"It's called glass, it's so good." Luo Lihua also sighed, then looked at Luo Gensheng and said, "Brother Gensheng, who do you say would be living here?" ”

"I think there must be a lot of people, everything is ready, and it is very neat, maybe it is the army, or how can a statue of Guan Gong be erected." In fact, Luo Gensheng was also very curious about who lived here.

"If it's an army, if you say there will be weapons, it's all stones, where will they train their troops?" Luo Lihua asked curiously.

"Maybe in the forest ahead, maybe there's a flat cave on the other side of this stone mountain." Luo Gensheng said suddenly, and then pulled Luo Lihua to the other side of the flint mountain, they went around the steep stones, came to the foot of the mountain on the other side, and saw that on the grassy mountain opposite, a hole more than ten meters wide had opened out of the mountainside.

"Pear blossom, look, there is also a cave on the hillside in front, maybe it is a place for the army to train." Luo Gensheng said and pulled Luo Lihua and climbed up. After a while, I climbed to the entrance of the cave, and the door of the cave was neatly inlaid with stones like the flint cave, and the top of the cave was written "Green Grass City".

"Why is it called Grass City?" Luo Lihua felt that the name was very strange.

"I don't know, either we can go in and have a look, maybe we'll know why it's called that when we look inside." Saying that, Luo Gensheng prepared a torch, pulled Luo Lihua and entered Grass City.

This place is different from the flint cave, although the entrance of the cave is neatly inlaid with stones, but after entering, only a steep staircase road is built, and the stone walls on both sides are a small platform every short distance, and there is still black fire ash on it, which seems to be the place where it is lit.

"Where is this going to go, why is it going down further and further?" Luo Lihua looked at the steps facing down in front of her with some fear.

"Don't be afraid, there's no one now, let's go in and have a look." Luo Gensheng said and held Luo Lihua's hand tightly, and the two walked cautiously for a few minutes, and finally came to a wide place, this place was really spacious, Luo Gensheng raised the torch, and there was no end in sight.

"Wow, it's like a square, it seems that this is where they trained, but I really didn't expect such a big place to be dug up by them!" Luo Gensheng looked at the spacious flat and said.

"Isn't this a cave? How can they say they dug it up? Luo Lihua asked.

"If it were an ordinary cave, there would be steps, where would there be such a flat ground, it must have been dug out, and you see, on the top, only the middle part is much higher, and the surrounding area is chiseled." Luo Gensheng raised his torch and looked at the roof of the cave.

"Who is so good at digging such a big cave?" Luo Lihua asked. As they were talking, they suddenly heard a "shuttle", and a black shadow suddenly flashed in front of the two of them, startling both of them, Luo Lihua hurriedly hugged Luo Gensheng's arm and shouted, "What is it?" ”

"Don't be afraid, maybe it's some small animal, I'm here, don't be afraid." Luo Gensheng hurriedly hugged Luo Lihua and comforted him.

"Let's get out of here, it's so dark inside." Luo Lihua said scaredly, but Luo Gensheng, who was very curious, still wanted to find out.

"Let's look inside, I think there's something better in there." As he spoke, Luo Gensheng took a few steps inside, and saw a stone pillar that was taller than him next to him, and he raised the torch to see what was on it, but as soon as the torch got close to it, the stone pillar began to burn.

"Huh, what's going on?" Luo Gensheng said strangely, and then looked at it, and it turned out that there was a depression at the top of the stone pillar, and there was some oily liquid overflowing there, and the fire came from there.

"What's wrong, what's going on?" Luo Lihua was also taken aback, borrowing the light of the stone pillars, they saw that there were stone pillars behind them, Luo Gensheng ran over and lit them up, a total of 15, five in a row in the middle, and ten around the flat ground next to them, these lampposts were lit, and the whole cave was as bright as daytime.

"Wow, it's really a big training ground, it's so spectacular, it's such a big training ground built underneath." Roganson looked around and said that they also saw a black hole at the end of the hole, perhaps the entrance to the inside.

Luo Gensheng wanted to go into the black hole to find out, but suddenly he heard a "rustling" sound, and then the next second he felt a wave of something floating in the air rushing out.

Luo Lihua heard the movement, looked up and was scared.

"Brother Gensheng, there's something coming over, let's go outside." Luo Lihua pulled Luo Gensheng and ran to the steps, but before she could run, she saw something flying out, which was a group of cave bats. They flew right next to the roof of the cave.

Luo Gensheng looked anxious, quickly extinguished the torch, pulled Luo Lihua to squat on the stone steps and did not move, and he didn't even dare to come out.

The cave bats spun around on the top of the cave, looking at the fire on the stone pillars and not daring to come down, but a few flew towards Luo Gensheng and them, and Luo Lihua's eyes widened in fright.

The bats looked very scary, "chirping" as if they were about to forage for food, staring at Logan and them, and seeing that the bats were approaching the two of them. But at this moment, the fire on the lamppost was extinguished at the same time, as if they had all heard a command.

As soon as the fire was extinguished, the bats were fluttering on the roof of the cave like headless flies, and the sound of them hitting the stone wall was heard, but after a few minutes, the movement gradually stopped, and Luo Gensheng listened to the silence, so he pulled up Luo Lihua, and climbed up the stone steps in the dark, and he was in a hurry to get out of the hole.

But as soon as she climbed two steps, Luo Lihua felt a hand grab her right foot, so she whispered: "Brother Gensheng, what are you pulling my foot for?" ”

"I didn't pull your feet, I'm in front of you." Luo Gensheng looked back and said.

"Ah, who's pulling my feet?" Luo Lihua was so frightened that she shook her right foot, shook off the thing that was holding her, and then climbed up quickly, but she felt that the thing behind her also followed him up the stone steps quickly, and Luo Lihua shouted in fear: "Brother Gensheng, something is coming with me, hurry up and pull me." ”

Luo Gensheng grabbed Luo Lihua and climbed up quickly, and by the time they climbed to the entrance of the cave, they were already exhausted. Luo Gensheng saw Luo Lihua's face flushed by the light of the cave, with beads of sweat on her head, and she was about to reach out to wipe her sweat, when suddenly she saw a strange thing coming up.

It seems to be a person, but it doesn't look like a person anymore. The hair on his head is yellow, covering his entire face, the skin on his body is also a black layer, the upper body and both arms are bare, and the body is simply wrapped in a rotten linen. As soon as he saw the light, he immediately blocked it with his arm.

"Ah, what's that?" Luo Lihua also looked back when she heard the movement, thinking that it was he who grabbed her feet just now, and stood behind Luo Gensheng in fright.

"Don't be afraid." Logan stood in front of her, then looked at the strange thing and tried to ask, "Are you human?" ”

The thing slowly moved his arm and looked at Luo Gensheng and Luo Lihua, standing on the stone steps, not speaking, just nodding in a wooden manner.

"Then since you are a human being, why don't you speak, and you are still alone in this dark hole." Luo Gensheng then asked. When the man heard this, he shook his head and shook his arms, and his mouth was "wah-wow-wow-la-la" to express something.

"You speak slowly, I can't hear what you're saying?" Luo Gensheng looked at him and gestured for him to come outside the cave, but he just stood still and pointed to his eyes.

"Are you afraid of seeing the light?" Luo Gensheng asked, and at this time, Luo Lihua felt that this person was a little scary, so she pulled Luo Gensheng's cuffs and whispered, "Let's go, maybe it's a mute." ”

As soon as she finished speaking, the man nodded vigorously, it turned out that he was really a mute, but then he squatted on the steps, gesturing something with his hand, Luo Gensheng wanted to go over to take a look, but was pulled by Luo Lihua.

"Don't go over, what if he breaks it?" Luo Lihua said vigilantly.

"I'll just stand there and see what he is doing, and I won't come near him." Saying that, Luo Gensheng took two steps forward, and looked at him gesturing, it turned out that he was writing, holding a small pebble in his hand and writing the word "flint".

Luo Gensheng looked very strange, how did he know about the flint, had he also been to the flint mountain, the flint cave.

"You know the flint cave?" Luo Gensheng asked again. Unexpectedly, he really nodded, and then opened his mouth, it turned out that there was no tongue in his mouth, and Luo Lihua gasped, it was too scary.
