The group transported the food and started walking up the mountain, but they set up another road. This road was unknown to those border troops. This secret passage was said to have been dug when Liu Xiu fled here, but then other people made some troubles here, so the small secret passage gradually became bigger and bigger, because there were bandits and the like on the mountain. Chen Yi also heard that there was a secret passage in Luming Mountain from a bandit who was originally Luming Mountain. Later, Chen Yi came here when he took time, and then he really did.

I discovered such a secret secret passage, but because I could not move too much, Chen Yi and the others just discovered an entrance and went back. This time, Dian Wei and the others came to open up the land. I don’t know how this place is now. Of course, Chen Yi, who came from later generations, knew that this secret passage that was uninhabited for many years, would definitely have a large amount of carbon dioxide, and carbon dioxide would cause people to suffocate and die, so Chen Yi opened the entrance of the secret passage to ventilate, and now he should be able to enter safely. The situation was like this that day. Come, edit the memory kill.

Chen Yi told Chen Xiang: "I heard that there is also a secret passage left by Emperor Guangwu in this place. After that, the bandits on this mountain kept opening up this secret passage, so that the secret passage with a little bit of artificial traces was completely opened up. This secret passage must do a lot of things. Let's take a few brothers here today. If you can find this secret passage, it will definitely be useful in the future. Call a few brothers who have not completely fallen asleep. Let's take the torch and leave now. Don't let the people from the border army know that we are probably still under their surveillance now. It's better to hide this action from them. After all, Gao Ming has not woken up yet (Let's think about the timeline of this action yourself). We have not reached a thorough negotiation with them. Let's go now, take the guy, don't know along the way.

What will you meet? Let's go." Chen Xiang also understood and immediately called eight people. Everyone started to follow Chen Yi with weapons and torches. Chen Yi also heard that there was a secret passage in this place, which was behind a large square stone behind Luming Mountain. There were two obvious red patterns on a large bluestone. It was actually difficult to find at night now, and they could not use torches casually. If anyone who got up at night saw the fire of these people, they would be alert, and then the cooperation would not be so easy to discuss later. But Chen Yi still wanted to find this mysterious secret passage. Chen Yi always felt that there were some places in this secret passage that attracted him or had an important role in him. This was the legendary intuition that no one believed, but sometimes it was really accurate.

Chen Yi and the others started walking around the mountain with the moonlight. Now this place is too close. Chen Yi asked that this must be far away from the village before lit a torch. At this time, Chen Yi began to be glad that his body does not have the annoying night blindness in his body, otherwise he would be supported everywhere at night, and this embarrassment would be huge. Chen Yi must now ensure that his wise and powerful appearance appears in front of his twenty guards. It is not a good deal of face, it is all for life.

When Chen Yi felt that he was a little far away, Chen Yi asked everyone to ignite the torch. In the Han Dynasty, there were three ways to ignite fire. 1. Use wood fuch; 2. Use gold fuch; 3. Use stone to pound fire. Wood fuch: that is, drilling wood to make fire. According to legend, ancient people "eat raw meat and drink blood" and did not know how to make fire for cooking. There was a man named Suiren (reportedly known as the Three Emperors together with Fuxi and Shennong) who saw a big bird pecking at wood and fire (some say that he saw the forest catch fire on its own), and believed that fire was hidden in the wood. So after "many of attacks and treatments and experiments", he created a method of artificial drilling wood to make fire, and humans had the first fire they took. This method has been passed down in later generations and has been around for thousands of years. This ancient legend reflects the progress of the primitive era of China from the use of natural fire to artificial fire.

In the Zhou Dynasty, the method of drilling wood to make fire has become very popular. The wood drilled in ancient times must be changed at any time in the year according to different seasons. The "Zhou Li·Month Order" stipulates: use willows in spring, jujubes and mulberry trees in summer, oak trees in autumn, and locust trees in winter, which is called "changing fire" or "changing fire". Because the ancients believed that only by matching the color of the wood with the four seasons can we get fire, and on the contrary, we cannot get fire. In other words, when the seasons change, we must change fire. In the Southern Dynasty, drilling wood to make fire was still carried out, but the custom of "changing fire" was abolished, and the wood was not changed. In the Han Dynasty, gold fuse was still used to make fire. At that time, it was also called Yang fuse. Even if we used a bronze mirror to make fire, we also used mugwort to make fire. In the Song Dynasty, the method of making fire in Jin fuse was still popular. Shen Kuo has a detailed paragraph in "Mengxi Bitan"

A detailed record: Use a concave bronze mirror to place it under the sun, and its light is concentrated inward. One or two inches away from the mirror, the light gathers into a point, as big as hemp and beans, and it catches fire when it touches it. In fact, this is today's convex glass mirror. If we take this glass mirror and face the sun, the mirror will gather like beans, and then use flammable objects to place it underneath, and fire will be obtained in an instant. There was no glass in ancient times, so the modern sun stove developed from this principle. In the past, the ancients brought flints with their side. Because flints at that time were pointed cups and were very small, they all wore their waists for use. However, there was one disadvantage to use the yang flints to make fire, that is, the fire could not be obtained at cloudy or at night. Therefore, the ancients often "worn gold flints on the left and wooden flints on the left". In this way, if there is a sun, the gold flints are used to make fire, and if there is no sun, the wood flints are used to make fire.

However, since our cute Chen Yi is a future person, how could he bear this ancient way of making fire? After all, it was in the Han Dynasty. It was a bit ironic when it was the whole diamond wood fire making arrangement, so Chen Yi thought of using flint to make fire. (I don’t know if you have ever played with this kind of flint when you were a child. It turned out that there was a small way to buy fire when you were in elementary school. This thing was very dangerous but quite exciting. Later, because of safety, it was very safe.

It is also a correct decision not to sell sexual problems, but the two flints really became a very strange memory. In ancient times, the method of knocking fire with stones was to use iron sheets to collide with stones, and there was "turtle velvet" below. When Mars fell on the velvet and burned, then used "lights" to connect to the guide, which means that the fire was obtained. The turtle velvet is made of mugwort or paper, made of nitro water, kneaded to make it soft and easy to catch fire. "lights" are called "candles" in the north, and are made of faded hemp straw into small pieces.

, five or six inches long, with sulfur on the head, burning when it encounters fire, and is used to get angry. Chen Yi made a little improvement on these, adding some vegetable oil to allow him to burn better, that is, there is no oil at this time, and many technical inconveniences make Chen Yi seem to be innovative. Fortunately, it is not that difficult to overcome this with a little brain. Soon everyone knocked on the stone and lit the torch. (It turns out that there is a lever that says that torch cannot be ignited on rainy days. That, if you use water to extinguish the oil, the fire will only continue to spread. Water is not omnipotent. The principle of water extinguishing fire is to isolate oxygen, and the other is to reduce the temperature. Does the torch simply burn wood? Or should it be vigorously popularized fire protection knowledge?) The group of people searched the mountains with torches for a while, and the sky was as wished by others. Everyone quickly found the big stone described.

If you want to know what happens next, let’s talk about it next time.
