The general's face was flushed. Although the city under Daerban was indeed complicated, and Tuoba Xiongxin had deliberately blocked it before, this was indeed a huge negligence that could not be justified for the army's battle.

"What's the situation of the battle now?" Xia Baying did not deliberately give up the general's face on this issue. As the supreme ruler of the Xia Ba tribe, she is already very good at means of giving equal kindness and power.

"There are about one hundred to three hundred enemies discovered at present, and the specific number is unknown." The general responded quickly, but the embarrassment and shame on his face became stronger: "They are all in that underground palace. Now we have managed to open up several passages to this underground palace, but the entrance of the underground palace is just built on a dry underground river, with the cliffs on both sides at least a few hundred feet high. The passage to the underground palace is like a bridge, with a length of four or five hundred steps. The most important thing is that the underground palace opposite the bridge is not known to be artificial.

It was the natural Fenghukou mouth. The storm that came from the wind was too cold. It was like the mountain wind on the top of the snow-capped mountain. It was not tight and could not breathe, and it was frozen so cold that people were stiff. The arrows shot out on the opposite side were like arrows shot by the cultivator's arrow master. We have organized more than a dozen charges, and hundreds of people were killed or injured, but we still couldn't rush over. We can only judge that there were about one hundred to three hundred enemies on the other side, and we can only see clearly that there should be an underground palace behind this bridge-like passage, but it is still unclear how many people there are inside."

Lin Yi and Bai Yuelu looked at each other, and they finally understood why the general was becoming more and more ashamed. It turned out that the army of Xiaofeng Yingming was good at fighting underground, but after working for a long time, they were still blocked outside the underground palace where they were discovered. They didn't even understand the exact number of the other party. At best, they opened up several more roads to the entrance of the underground palace below.

"The underground palace is backed by the center of the mountain. It is unlikely that it will open the passage from other directions of the mountain, and I don't know if there are any other exits. We have arranged for troops to patrol the periphery so that they will not leave the city elsewhere in the underground palace."

The general continued: "General Xifeng Yingling was supervising the battle below. He could not attack for a moment. He was afraid that there would be any change, so he quickly informed General Lin for help."

"Is there a possibility of a complete collapse of the mountain below?"

Xia Baying frowned and said, "Don't let us go down then. They will use some means to bury all of us in it at that time."

"This Daerban City is actually hard, and many authentic tunnels and caves have been reinforced by various means. These authentic reinforcement methods are like adding countless muscles and bones to this mountain. Even if they use magic circles or other special means to cause strong earthquakes, it will not cause the entire city to collapse completely. At most, it will be small-scale collapses and rockfalls."

The general glanced at her and Lin Yi and said boldly: "Ordinary sergeants may encounter such a small collapse and cannot escape, but with the strength of you and General Lin, you should not do anything to you. As for poisonous fire and poisonous gas, we have some precautions. We also have methods of isolating and extracting in the tunnel, so that even ordinary sergeants will not suffer large-scale casualties."

Xia Baying silently said in her heart, "I believe you, a ghost."

She didn't believe the judgment of these subordinates who were named Yingming at all. If Tuoba Xiongxin was really hiding in that underground palace, there would be many dangerous possibilities. The key to this kind of vision lies in how high a person stands.

Many things are impossible in the eyes of practitioners in Chengtian realm, but they are different when they reach the divine consciousness realm. If they are the three saints of the South Heaven, they are completely different.

But the more this happens, the less she can let these people waste time. She has to watch it in person before she can rest assured that there are secrets and conspiracies hidden in the underground palace.

She glanced at Lin Yi and knew that Lin Yi had the same thoughts as her at this time, so she stopped saying anything and said, "Then take us down."

...

The authentic tunnel under Daerban City reminded Lin Yi of the first time the tomb of the ancient tomb.

Jiankang City has been a major city of the southern dynasty since ancient times. Many dynasties in history have regarded Jiankang as a royal city, so many places where large-scale construction is built inside and outside Jiankang City often dug out ancient tombs.

Lin Yi remembered that in the years when he just started studying, there was a heavy rain in Zhongshan that caused a landslide. One landslide revealed the holes of two ancient tombs. He was so brave that he even asked his father's subordinates to take him to see it.

That kind of tomb is not hidden in the mud, but is forced to open the mountain and dig the passage in the mountain. I don’t know if the ancient tomb he saw was left by a king in ancient times. In short, it is much more complicated than the tomb he imagined at that time. It not only has passages for people to walk, but also lead to various tomb chambers. There are also many passages for drainage, humidity, and various mechanisms. Some holes are even said to be used by craftsmen who were sealed inside after the tomb was built. Anyway, later scholars studied it and did not know what some of the passages more than half a person were used for.

When he asked his father's general to take him to open his eyes, the ancient tomb had been cleaned up, but the strange smell inside was still fresh in his memory.

The various underground passages of Daerban City are really similar to his impression back then.

Even though the army that had sealed the name of Yingming had placed lighting lanterns in every corner of the passage, and braziers were even set up in some places. The blazing fire light dispelled the suffocating darkness in the passage, the extremely rough stone walls and some deep twists that looked like steps but not like steps connecting them still gave people a feeling of discomfort.

The underground area of ​​Daerban City was a forbidden area, and the Tuoba army strictly controlled it. Many passage entrances were blocked with stone gates or iron bars. However, all toilets in Daerban City were not as particular as Jiankang, especially all the powerful people were not as elegant as those in Jiankang City. Their style can be described as heroic. Their toilets were directly cut out straight downward passages by craftsmen, which directly led to the depths of the underground or the underground river.

In the Southern Dynasty, very few literati would go deep into the city of Dangxiang for a long time. Otherwise, if they had a clear understanding of this point, they would have spent a lot of writing on it after returning, and would have depicted the city of Dangxiang as a city built on a manure pile.

However, Daerban City did not smell bad. In fact, this is really adapted to local conditions. The high drop and extreme cold and the cold wind everywhere made the water in Daerban City unable to emit much odor, and it quickly weathered naturally. Most of them were directly washed away by the groundwater flow and underground rivers.

The melting water of snow-capped mountains and snow-capped water easily melts a lot of filth into the invisible and penetrates into the wasteland that will only thaw in summer.

However, although the city of Dahlban was constantly blown by strong winds and there was no unpleasant smell, the smell was a bit undesirable in this underground passage.

And it is obvious that although Tuoba Xiongxin marked the city into a forbidden area, it does not mean that no one entered and that things were poured into it under various circumstances.

Lin Yi, Xia Baying, Bai Yuelu and others are not considered pampered people, but the smell of the cold wind rushing on their faces still makes their scalp feel a little numb.

Fortunately, the entrance to the Di Palace is not far from the ground, and the violent wind and pungent blood completely obscured the various strange sounds and the smell that cannot be described in words.

The intersection of several authentic tunnels is a cave of several acres of land, with a height of two or three feet above the head.

There are at least dozens of such places under the city of Daerban, and some caves are even larger. Some of these caves are natural water-soluble caves, some are formed by artificial quarrying, while others are specially developed for hoarding troops or stacking materials when the city of Daerban was established.

It is precisely because there are many such caves under Dalban City, and this cave is not an important node in the maze-like underground passage, so the army that had previously paid attention to this cave did not pay much attention to it.

A group of high-level generals and practitioners under the throne of Yingming's seat gathered behind a stone gate with the sound of wind. At this time, they were so upset.

Hearing the news that Lin Yi and Xia Baying arrived, the group of high-level generals and practitioners quickly asked the dense soldiers who were crowded in the cave to get out of the way, and they all rushed forward with a hot face.

The highest general here is Xifeng Yingling. He is the cousin of Xifeng Yingming, who is also considered to have the blood of the Xifeng royal family. He is a middle-aged man who looks over forty years old and has a strong figure.

"General Lin."

Looking at Lin Yi who appeared in front of him, although he felt extremely embarrassed, he still told the truth: "There is only seven or eight hundred steps away from here. There is a larger cave. We originally planned to be one of the soldiers who hoarded the troops there. We even made a lot of arrangements there. In this place, our soldiers have passed by dozens of times. No abnormalities have been found before. If this stone gate was not opened by us, even if it was shining with fire, we could not see it. It just so happened that there were some mastiffs in the Tuoba family's own surrendered army. We knew the general who was in charge of the mastiff before, so we borrowed it at the beginning of the search. Only then did we find that there were traces of people passing by, and then we strongly opened the stone gate."

Lin Yi was quite patient, but Xia Baying had long since lost the patience to listen to the general of the Seifeng clan explaining the whole story.

She glanced at the sight and found that the so-called gravel on the ground at the entrance of the underground palace must have been completely broken. The gravels were covered with blood and broken flesh, as well as many broken arrows.

The entrance is not small enough to accommodate a carriage passing through, and the width behind the entrance is incredible.

From her position at this time, there was a black ocean inside, but you could also vaguely see a passage like a stone bridge floating above this deep black, leading to the distance behind.

Lin Yi had better eyesight than hers, and he could see clearly that the passage that seemed to be like a natural stone bridge was slightly tilted upward, and was wider than the entrance, enough to accommodate two carriages walking side by side.

But on both sides of this passage, there are dark abysses.

The passage is indeed only about four or five hundred steps long and has reached the end. At the end is a real underground palace, and it is not an underground palace like a cave dug out from the natural mountain wall, but a palace built on the mountain wall with huge stones.

He narrowed his eyes slightly. The palace was actually in the shape of a spire. There were three spire, the one at the back was the highest, and the other on both sides looked like a main hall in the middle, and there were side halls on both sides.
