The first prince of Song Dynasty

Chapter 1832 The Eternal Light

Speaking of the ever-bright lamps, the most common ones appear in some ancient tombs. A kind of ever-bright lamps have a double-layer structure. A container inside is filled with kerosene, the wick is soaked in vinegar, and the outer layer is filled with water to cool the lamp oil.

This is a great invention, because the oil consumed by the oil lamp is not mainly ignited, but volatilized by heat. The wick soaked in vinegar can not only keep the temperature low, but the water outside the oil jar can also effectively prevent the oil temperature from rising, which can make the lamp last for a long time. Ignite Changming.

In China, it is said that on New Year's Eve, when the gods go to heaven, all the ghosts and gods come out to look for food, especially those ghosts, sprites, and monsters.If the lights are blown out and the sky and the earth cannot be seen in the dark, it will arrest people along the way, especially if children cry in the middle of the night and old people cough, their lives will be in danger.

There are many similar records. It is recorded in the historical records that there was an ever-burning lamp in the tomb of Qin Shihuang; Chinese people have a tradition of treating death as life. I hope that the lights will always be bright like the palace in my lifetime, so there will be always lights.

At this time, Zhao Xu's biggest one is the ever-burning lamp, and in some places in the city, there are these ever-burning lamps working dedicatedly. These ever-burning lamps are not on the ground, but in those secret passages, where they are not blocked. They found that this is also a technical activity.

In fact, this secret passage was built twice. In the past, it was just a tunnel for transporting troops. I don’t know how many years ago it was left. Just like Cao Cao’s military passage found in some other places, this is not actually a tunnel. It was simply excavated by hand, but before the city was built, there was already a secret passage here. At that time, it was verified that the secret passage here had existed for at least hundreds of years, and it was unknown whether it was the masterpiece of the emperor or general. .

The reason why it is so certain that it is the emperor or general, at first there were weapons and other supporting documents, all of which were not built by ordinary people, and finally Song Dynasty built this city here, and these intact secret passages But it has been preserved. In fact, it is not complete. What the Khitan discovered were those that were complete and usable, and many of them were useless, and those that could not reach outside the city, but they were not destroyed when the city was built. A secret passage leading to the outside of the city.

It's just that they used it as a storage room, and no one would pay attention to it on weekdays. In fact, Song Jun had concealed it a lot at that time, and Khitan has not discovered it until now. Besides, those entrances are in the storage room.

At this time, there are eternal lights in the storage room. Although the eternal lights have the word "eternal bright", they cannot be extinguished for a long time, because they will be extinguished due to lack of oxygen, but the dozens of eternal lights in the storage room are not extinguished. After being used as storage rooms, these incomplete secret passages have been remodeled so that they can communicate with the outside world, which means that there is oxygen to ensure combustion.

I'm afraid you would never have imagined that the network of these secret passages can almost cover the entire city, but most people don't know about it at all. There are only a few used as storage rooms, but there are everlasting lamps everywhere in the secret passages. .

"I'm sure it will burn out tonight. If the calculation is inaccurate, our loss will not be small. Whether those people in Gao Huaide can come back alive is another matter. Liu Qinhu, I'm not joking with you, this is a very serious matter." The problem is related to the lives and deaths of thousands of people, if it doesn’t work, I have to go to the city to see it myself, otherwise I won’t be relieved.”

Zhao Xu said that he was about to enter the city. Although it was occupied by the Khitan people, after all, Song Jun had stayed here for many years and knew everything about it. There was still a way to enter the city. Zhao Xu was so confident.

"Your Highness, if you are worried, I can go there in person. You must not come out. It's not that I don't believe you. After all, I am responsible for your life and safety. In addition, your light work is not as good as mine, so I will go now." It's better."

Since Zhao Xu was worried, Liu Qinhu decided to go see it himself. He also knew that Zhao Xu attached great importance to these things, especially when it was a matter of life and death. He had absolute confidence in his own skills, which was why he An important reason to be willing to take the initiative to go.

"After I left, Dong Zhenhai should be brought back. To be honest, he doesn't have much military talent. You asked him to follow Cui Yanjin to protect General Cui. Now General Cao Bin leads the troops not far behind him. General Cui and the others are safe, so Dong Zhenhai won't be of much use to him, let him come back and follow you."

Zhao Xu can't be without people by his side. If Liu Qinhu is going to enter the city, then Dong Zhenhai will be back. Zhao Xu can't be without people by his side. After all, his safety is the most important thing, otherwise they will never rest assured that Zhao Xu is alone human.

There was silence in the city, and Liu Qinhu had already entered the city. After he arrived in the city, he immediately changed into a set of Khitan clothes. Don't forget that Liu Qinhu came from Suyiwei, and language learning is also one of his skills. It is still easy to speak some Khitan dialect, so how important it is to master a foreign language.

Liu Qinhu was not alone, he brought a few people with him, and they formed a small team, so that they could walk in the city openly and aboveboard, and they also encountered cross-examination by the Khitan people, but they were fooled by them. It was dark, so it was easy for them to sneak in. They purposely entered various places in the city. After arriving at a certain place, Liu Qinhu would disappear for a while and return soon. This delayed them for more than an hour. Leaving, but Liu Qinhu left, but the others did not leave, they went towards the city gate.

"Your Highness, don't worry, old Liu Na is a very thieves, don't worry about his life, besides, we also have a way to escape in the city, I believe he will be fine."

Dong Zhenhai looked at the restless Zhao Xu, did he know that he was worried about Liu Qinhu? In fact, he was also worried. Liu Qinhu has been gone for so long and there is no news, which is really worrying.

"I am not only worried about him, but also whether our intentions will be discovered. We have passed so many days. If we fail this time, our plan will not only lose everything, but those people led by Gao Huaide will also be in danger. Now, whether Liu Qinhu succeeds or not has a lot to do with it."

What Zhao Xu cared about was not only Liu Qinhu's life, but his own life was insignificant compared to these hundreds of thousands of lives.

"Your Highness, you're back. Commander Liu is back." The orderly shouted, and Zhao Xu's face was filled with joy.

"Your Highness, I'm back. The situation in the city will improve around tonight." Liu Qinhu's face was covered with ashes, and he couldn't see the true face of listening, but Zhao Xu was still very happy to hear this, his The plan was almost half successful.
