Bu Zheng and his party entered the cave entrance and walked down three to four hundred meters from the cave entrance before completing the downward slope. This made people feel as if they had gone deep into the ground, but in fact it was only more than 20 meters deep.
But the more than twenty meters underground is actually very deep!
What was in front of everyone at this time was a straight passage leading into the distance with no end in sight!
Although the passage is more than 20 meters deep underground, it is very bright. It seems to have a special lighting system. This seems to be natural light.
This underground passage seems to be made of transparent glass, using some refraction and reflection systems to introduce natural light into the ground. At the same time, when there is no light at night, you only need to add light sources in some places to illuminate many places.
But it's definitely not as bright as during the day, but it allows people to see clearly what's inside.
Also, the walls of this underground passage are made of thick refined earth walls. Yes, they are walls of earth, but the refined earth is no harder than any rock, and it can also be refined with tools.
By refining the cracks in the soil together, this building material is simply unbelievable.
Not only is the effect great, but the materials are as much as you need!
At the same time, the thickness of the refined earth wall in this passage is up to ten meters. Even the warriors of the Hunyuan period will take some time to destroy it, but who among the warriors of the Hunyuan period would do this.
This also eliminates the possibility of intrusion by ferocious beasts. Originally, there are very few ferocious beasts underground, and even if there are, they will not be high-level ferocious beasts. This kind of refined earth wall can block these ferocious beasts from the outside.
There are many more details about these things. This is what Bu Zheng wants to see today. Of course Xiuying who is with him can't see these now. At the same time, she doesn't need to see them. She just needs to ask. Anyway
She knew she wouldn't understand even if she looked at it, so she still had to ask.
"What's this?"
"Do you still need to ask? Of course it's the underground passage!" Bu Zheng continued to walk forward, while also looking at the situation around him.
"I don't know this is an underground passage. I'm asking, what is this underground passage used for and where does it lead to? It seems very far away. How far is it?" Xiuying set up a tent with her right hand.
She looked out into the distance, as if she wanted to see something, but happily, she couldn't see anything.
"You asked me so many questions, which one do you want me to answer?" Bu Zheng replied casually, and he soon came to a ground in front of him. The ground here seemed a little different from the previous one.
There seem to be several straight lines on it, but these straight lines seem to branch out into some special patterns, one for each section.
"Of course, answer them all, one by one, and now I want to add a question, what is this you are looking at?" Xiuying then asked, all of this is a mystery to her, and she really wants to know what it is.
What.
"Answer one by one, let's start from the first question. This underground passage is of course used for walking people and transporting goods. Where does it lead to? That place hasn't been named yet, so it's called Jiazi Castle.
Come and take over temporarily." When Bu Zheng said this, he casually said a name, and this name eventually became the name of the new city.
Jiazi, the first arrangement of the heavenly stems and earthly branches, obviously means that this is the first city, but this name seems a bit arbitrary!
"Jiazi City? What you mean by this is that at the end of this passage is a new city. Are you planning to build a new city?" Xiuying asked.
"Seeing you like this, I think it is a very wise choice to separate the throne and political power. Fortunately." Bu Zheng looked at Xiuying, shook his head and said.
"What do you mean?" Xiuying glared.
"That's what it means literally. Even if you are practicing, you still have to care about your empire. What are the two of us busy with? The biggest thing is not to prepare to expand the territory, but building a new city is the biggest thing.
Otherwise, it is an imperial capital with already rules, so why should I be so busy?" Bu Zheng shook his head, looking helpless.
"What, how do I know so much? Didn't you ask me to practice?" Xiuying said a little weakly. Although it was a bit strong, it didn't sound very powerful.
Bu Zheng nodded at this time and said: "Blame me, I shouldn't blame you. Anyway, it's useless for you to know, and you can't help. It's okay to know now, no, it's okay to know in the future!"
"You mean, I'm stupid? Boy, don't forget, I taught you to read and write when you were a child." Xiuying said immediately, are you questioning my identity as a sister? I think so.
I need to remind you how stupid you were when you were a child.
"You still have the nerve to say that if you hadn't taught me, I would have been able to read and write a long time ago. It was you who taught me to be an illiterate idiot, but only you can do this." Bu Zheng looked at Xiuying.
, and then said lightly.
"..."
Everyone was speechless. What was going on? Could it be that Young Master Bu Zheng was an illiterate when he was a child? And this was actually how the Empress taught him to be.
The question is, how can you teach this? The Empress is indeed extraordinary.
"This is not necessarily my fault. Maybe you were like this because your brain was damaged by the seal when you were a child." Xiuying said weakly.
"Anyway, I blame you. You will bear the blame for the rest of your life." Bu Zheng didn't care about that. Anyway, he believed that it was Xiuying who taught him bad things.
"Ahem, let's not talk about this. You haven't finished answering the question yet."
"Oh, what did you just say? By the way, let's talk about how long this passage is. It's not very long, it's only five or six hundred miles." Bu Zheng continued to talk about the question just now.
"What? Five or six hundred miles? It's so long. How long will it take to build it?" Xiuying was a little stunned. This seemed to be too long.
"It's almost half done. It will be completed in a few months." Bu Zheng replied.
"..." Xiuying was silent. She found that what Bu Zheng did was even more unimaginable than she imagined.
"Sir Xiuying, we are working hard to build, mainly with the formations made by the young master. Whether it is digging passages or building walls, roads and other facilities, it is very convenient, but it requires energy consumption." At this time, someone explained to Xiuying.
Now, there are still a large number of arrays running in this passage, but they are under construction and not here, so it feels very quiet here.
And the man finally said: "Sir Xiuying can see it later."
"We want to go see it? Then why put the horse on it? Do you have to walk there, more than two hundred miles away?" Xiuying was a little confused. It didn't matter if she went to see it, but she would have a headache if she had to walk.
"Of course you don't need to walk, you'll find out later." Bu Zheng smiled mysteriously.
"??"
What, why does it need to be so mysterious? (To be continued.)
