I walked forward and pushed with my hands, but the piled stones were so solid that it was difficult for me to move them.

Outside there are stone statues that are very old and slightly mottled. Both of them are holding weapons and standing in a guarding posture. Behind them is a cave, which makes it hard not to have other associations.

There are only two reasons for building stone statues here and digging caves. One is that the person who built it was of noble status and, in accordance with his own style of doing things, built two stone statues with consistent body proportions, nearly 1.9 meters tall, to declare his status and identity in a solemn manner. This cave was probably the owner's old residence, and he blocked it because he did not want future generations to live there.

The second reason is more far-fetched, but it is true that ancient people believed in gods and were therefore more superstitious. They believed that there were many evil spirits and monsters. Looking at the standing posture of this stone statue, I think it is similar to a door god. Therefore, I think another purpose of this stone statue is exactly this use, to serve as a door god, guarding the residence, and intimidating evil spirits.

But no matter what, this blocked cave is most likely the place where the old ancestors of the Western Zhou Dynasty lived. Although I am curious, it is difficult to shake these stone piles by myself, so I can only speculate for fun, and there is nothing else I can do.

Although I couldn't see with my eyes, I still put my ear to the pile of rocks at the entrance of the cave and listened to the noise inside. There was the sound of dripping water and even some wind. It seemed that there was a great possibility of underground water in the cave. I continued to listen. It was quiet for a long time. Just as I was about to give up and leave, I suddenly heard a strange sound!

I collapsed to the ground, staring at the stone cave entrance in disbelief.

It is currently speculated that this cave has only one entrance, and it is blocked by rocks. It is hard to say whether there are any living creatures living inside, but I clearly heard the sound of human footsteps just now. How weird is that?

I quickly moved away from it. I thought to myself that I had just been laughing at the superstition of the ancients, but now I was also frightened out of my wits by this mysterious and inexplicable phenomenon. It was really ridiculous.

"I must have heard it wrong! It must be a bat or a lizard hiding in there. It definitely wasn't the sound of human footsteps. That's absolutely impossible." I said, patting my chest.

But I still thought about it. If there really were people living there, it would be impossible for me to have never seen them. Besides, the air, food and other things in there are totally insufficient, and no one can survive there.

And if it is not a human, could it be?

Forget it, forget it. Confucius said, "Respect ghosts and gods, but keep them at a distance." I should listen to the saints and not provoke these things.

Thinking of this, I hurriedly left the place. When I passed by two guarding stone statues, I bowed to them specially, hoping that even if there was any dirt, it would be suppressed.

Then I went back to the top of the mountain. Now I could only cook with the metal cups I brought back from the plane, which were totally inadequate. Yingchun refused to do anything, so Yunwen had to do her job.

Fortunately, Yunwen had already written down the steps that Yingchun made. Although the baked earthenware basins were not as exquisite as those made by Yingchun, they could still be used. At least they could be used to make soup or stew something.

I counted the current supplies, including three bronze objects, 26 edible fungus, and the rest of the fungus still growing, wild grass, wild roots, wild berries, and a small snakeskin bag, 12 slices of air-dried beef, and all the tools, including an engineer shovel, a saw, hemp rope, a bayonet, and an additional cargo tool, a wooden ox and a flowing horse. Finally, there was my gun. Although it was a sharp weapon, there were only five bullets left.

Of course, we also harvested three animal skins. When night came, we used one to make a tent, one to make a bed on the ground, and one to make a quilt, which was much warmer.

And just like this, we relied on these supplies to survive for three or four days. During this time, Yingchun came occasionally to eat and drink, but she was in a bad mood and refused to move. I knew she was angry with me and felt that I was too indifferent to Bailu's matter and treated her poorly, but I have my own way of doing things and I don't owe her anything in this matter.

When we were hungry, we ate the leftover supplies. When we were thirsty, we drank water from the nearby spring. Our lives were worry-free for the time being, except that we would occasionally see vultures circling in the sky, which would make us feel uneasy and scared. However, we mostly saw them during the day, so if we saw them, we would hide among the bushes and stay away.

I have never mentioned the cave below to them, but if it is not so weird, I really plan to try to find a way to open the pile of rocks and develop and use the cave for living.

During these three or four days, we have slowly adapted to the days without Song Bailu. We do miss her, but these worries have been slowly replaced by other daily necessities. I have completely given up hope. Even if I haven't seen her body now, I know that she will never come back.

On the fourth day of living on the top of the mountain, we all got up early, packed up, and after eating the usual breakfast, I gave instructions to do the task, saying, "Yunwen, hide all the food in the tent today to avoid attracting birds of prey such as vultures or sea eagles. Then help pick up some firewood and look for wild grass and fruits nearby. I need to thresh the grain in a while. After you finish here, come down and help me sort the grains and put them into the warehouse."

"Okay, no problem." Yunwen said.

"Song Yingchun, I can allow you to be lazy for one more day today, as a recognition of your deep love for your sister, but there is no free lunch in the world. If you still behave like this tomorrow, I'm sorry, but there is no order without rules. I can only ask you to leave. Since you are staying at home for a long time now, please help watch out for food. Also, pay attention to protecting yourself. If there are any birds of prey coming, hide in the bushes immediately." I warned.

After that, Yunwen and I packed up and prepared to go back to work. We didn't expect Song Yingchun to be able to do anything. Unexpectedly, she, who had been almost mute these days, spoke up: "Brother Zhou Bo, threshing requires tools, and storage also requires a warehouse. If you don't prepare these, where are you going to put the threshed wheat later?"

"That's right. You need a flail for threshing, a rake for washing wheat, and something to hold the wheat in the bin," I said.

"Let me do it. I'll go down with you." Song Yingchun's voice was a little low, not as high-pitched as before.

I was a little surprised, but thinking that it really required her manual work to finish it, I nodded and let her follow me.

Seeing the slightly relieved look on Yunwen's face, I also let go of the knot in my heart. I put the saw and shovel in my backpack, and took Yingchun down the stone steps to the wheat field, looking at the dried wheat on the ground.

Then Yingchun looked around for dry branches, some long and some short. She first used a saw to cut the shorter branches into the same length, about an arm's length. Then she used a bayonet to cut some wooden nails. She broke off some branches and clamped the six shorter branches horizontally in front and back. She fixed them with wooden nails, fixing them in both the upper and lower places.

I went to cut some thinner vines and tied up the cross-sections to reinforce them again, so that six branches of the same length were tightly connected together to form a board. After that, after sawing long branches, I made a long and big wooden nail, connected the long branches and the board, and widened the tail.

A movable axis is formed, which forms a flail. When the pole is swung, the force affects the movable axis and swings the board surface. In this way, the wheat can be beaten and threshed quickly.

"The flail is ready. The next step is the barn. It's hard to find raw materials right now. We need to go down the mountain and get the unused wooden boards from the abandoned houses." Song Yingchun said.

This proposal made me look at her in a new light. When she got serious, she really had some sense.
