In fact, Fang Nian really admires the person who chose to be here as a tomb, and I have to say that his mind is definitely clear enough, because this natural cave, the natural conditions are really good, if it is Fang Nian, after learning Feng Shui, it is estimated that he will also choose such a scene to build the tomb.

The reason why Fang Nian said this, looking at the situation around him, he wanted to judge the position of the two of them now. If the entire city and the natural cave underground are considered to be a tomb, then the first point is the light source, and by looking at the structure of the main tomb dome that is the tomb here, it can be seen that 80% of the dome is covered by a black rock except for the top of the waterfall.

From this, Fang Nian can be sure of one thing, that is, the place where he and Cai Wenji are now should be underground, not the ground, so it can be considered that there should be no sunlight here, but obviously, there is enough light here to illuminate the entire main tomb, that is, the light here is a special material or the light emitted by something.

The second is the area, if it is a traditional tomb, then even if it is the main burial chamber of a tomb, the area of construction should be very limited, but here, it is not an exaggeration to say that it is a cave, and the entire tomb has an area of 10,000 square meters.

And the most terrifying thing is that there is actually a city among them, you must know that a city is packed into a tomb, a tomb of this scale, I am afraid that even Qin Shi Huang back then, he has never thought of it, but what is the reason for this, Fang Nian does not know.

After Cai Wenji did it on the ground for a while, she also eased up, and her face gradually became rosy. Although she hated Fang Nian's pen, she always quarreled with him.

But it is true that Fang Nian hugged her all the way, and he saved her life in such a crisis just now, and he can be regarded as her life-saving benefactor.

After pondering for a moment, Cai Wenji suddenly turned her head to look at Fang Nian, and said with some embarrassment at the corner of her mouth.

"Just ...... Thank you. ”

Fang Nian was thinking about what to do next at this time, whether to move forward or look for Jia Xu and them nearby, when he suddenly heard Cai Wenji write like this, he was slightly stunned, and after a while, he actually looked at her with a dry smile.

"Are you talking to me? What did you say? I didn't hear clearly, the sound of the water was too noisy. ”

Cai Wenji knew that Fang Nian understood, and he was just deliberately pretending to be stupid, but he couldn't do anything about Fang Nian, so he could only say it again.

"I said thank you just now for saving me."

Fang Nian knew that this ancient person was thin-skinned, so he didn't tease her.

"Thank you, we're not partners."

Cai Wenji was stunned for a moment, with a suspicious face.

"Partner? What partner? ”

Fang Nian was speechless for a while, then explained aloud.

"A partner is a person who joins forces or ties closely with another person to form a pair and do something together...... Well, it's a partnership, let's partner, partner ......"

"Hey, you didn't say it, let's think about what to do next."

After sorting out what happened before and some of it -- >>

After the clue, Fang Niang and Cai Wenji also got a relatively unified answer, that is, to enter the ancient city in front of them.

As for Jia Xu and them, Fang Nian was actually not worried, you must know that those people are all well-known figures in this era, and they should not die here so easily, maybe they have already entered the ancient city at this time.

However, in addition to this, Fang Nian also had a feeling that the danger in this ancient city should be far beyond their cognition, so Fang Nian thought that he had to enter in the best state, so he finally decided to rest by the river for one night and enter the ancient city again the next morning.

Waiting until the next morning, as soon as the sky was bright, Fang Nian and Cai Wenji packed up all their equipment, glanced at each other, and walked towards the ancient city, towards the source of all the puzzles.

But not long after they left, they saw a group of people on the mountain, about 4 or 50 people, each wearing a military uniform and holding a weapon. The leader walked in front, very tall, and at a glance Fang Nian recognized that person was Bai Zhe who had entered the hunting ground with Fang Nian.

Fang Nian stared at Bai Zhe, a hint of joy flashed in his eyes. At first, Fang Nian guessed that this Bai Zhe had at least brought a few hundred troops into this pregnant dragon's lair.

But now it seems that in addition to the messy armor on his body, some of them are also injured, and they have been severely injured at first glance, and now it seems that these people are also injured, which is the best news for Fang Nian.

However, what Fang Nian didn't expect was that this guy really had some ability, and he actually found it here. Then since the opponent has also found here, Fang Nian can't delay any longer, after all, they are also a game, and it won't look good if they lose.

Thinking of this, Fang Nian pulled Cai Wenji and entered the city through the east gate opposite Bai Zhe and the others.

Walking in the ancient city, looking at the old houses next to it, Fang Nian said with some emotion.

"Judging from the newness of the city wall, this ancient city should have been established for at least four or five hundred years, and it was when the Qin Dynasty had just unified the country and the national strength was prosperous, so the ruler at that time, Qin Shi Huang, ordered the construction of the Great Wall to resist foreign enemies."

However, because of the limited natural conditions and congenital conditions at that time, the materials for building the Great Wall were also relatively messy, with earth, wood, and stones, and many places were made of local materials. In some remote desert areas, even reeds or red willow branches are used to spread sand layer by layer. ”

"The Great Wall north of Shuofang County, where we are located, was built using this third method. Its construction method is very special, first need to lay a layer of reeds or red willow branches, then lay some sand and gravel, and then lay a layer of reeds or red willow branches on top of the sand and gravel, and so on, if you want to build a city wall with a height of about three zhang, the thickness of the reeds at this time is about less than half a foot, and the sand and gravel are more than half a foot, so you need to lay about 30 layers. ”

"This method was also a method created by Qin Shi Huang, the supreme ruler of the Qin State at that time, and then this method was widely practiced in major regions, but because this method consumed a large amount of manpower and material resources, and the buildings built were not particularly strong, so at that time, in addition to the construction of the Great Wall, few people used this method to build buildings, and in the end this method was even forgotten."
