Judging by the architectural style of this underground palace, as well as the armor appearance of the soldier statues outside before, how can it have a history of thousands of children and eight hundred years, right? It's already quite incredible that those mechanisms outside can still work, and those very beautifully carved stone braziers more than a meter high can still spontaneously combust? And looking at the fire, I am afraid that it will not be extinguished for a while, which can't help but Zhang Yu marveled at the words of the ancients who listened to the party, even if it is still incredible.

"Don't go in......." Zhang Yu's eyes were quickly scanning the scene behind the city wall, observing the buildings in the distance that were enough to be described as splendid, Wang Lao and Ying Jiang paused a little and then continued to move forward, Zhang Yu subconsciously wanted to follow the two of them, but suddenly found something abnormal, from those burning braziers, there were streams of faint green smoke coming out of it, those smoke was slowly drifting around, green smoke? What the hell does that thing have to be normal?

"How?" As soon as Zhang Yu's voice came out, Wang Lao and Ying Jiang immediately stopped their steps, and then looked at Zhang Yu in some surprise. Even because of the use of spiritual sense, the two of them saw much more things than Zhang Yu saw, Zhang Yu could only see a small area of buildings in front of him at most, but Wang Lao and Ying Jiang had almost seen this place, this whole thing was completely an underground palace, but they didn't know what kind of power there was, so the two of them couldn't investigate what was inside too closely. But even so, it also made the two of them find some slightly more obvious trap arrangements, but these arrangements are still far away, so Zhang Yu's voice had to make the two of them puzzled.

"Don't you feel something unusual about the smoke from those flames?" Yes, just looking at the eyes of Ying Jiang and the others, Zhang Yu could see it, and the reason why he could see those green smoke must be because of his eyes, but Zhang Yu still told the situation, after all, those flames themselves burned smoke, even if Wang Lao and they were different from what he saw. It doesn't prevent him from saying this, does it?

"Smoke?" I heard Zhang Yu talk about smoke. Wang Lao and Ying Jiang used their spiritual sense to observe carefully, and after this observation, their brows suddenly furrowed again, not because they had found something. And it was precisely the smoke that seemed to them to be ordinary smoke and. But the two of them also believed Zhang Yu's words in their hearts. Since Zhang Yu said that there was a problem with those smokes, there must be something wrong with them that they didn't find.

"I think there's something wrong with the smoke, the color of the smoke is a little abnormal. Could it be some poisonous smoke or something? As soon as he saw the appearance of the two of them, Zhang Yu immediately knew that the spiritual sense of the two was useless in front of those smoke. No longer beating around the bush with the two, Zhang Yu said directly to the two. Don't look back and rush in, but the three of them are all planted under those poisonous smokes, which is called a depression.

"Toxic smoke?" Wang Lao's eyebrows raised slightly, and as soon as the words fell, the whole person suddenly disappeared in front of Zhang Yu's eyes, and when he reappeared, he had already arrived next to a brazier closest to them, and after standing there for a little for ten seconds, Wang Lao's figure returned to Zhang Yu's side again.

"It's indeed poisonous smoke, and the toxicity is very domineering, but it doesn't have much effect on us, and the monks below the martial sect are afraid that it will be troublesome." Coming to Zhang Yu and Ying Jiang's side, Wang Lao stretched out a hand in front of Zhang Yu and Ying Jiang, both of them could clearly see that in just such a while, Wang Lao's hand had turned purple and black, and it was also possible to imagine the domineering toxicity of the poisonous smoke, but the poison was really like that for Wang Lao, after Zhang Yu and Ying Jiang looked at their hands, Wang Lao shook them casually, and the hand that had already turned purple and black was quickly restored to normal.

"Don't worry, although these poisonous smokes are a bit powerful, they are just ordinary poisons, with us, you don't have to worry that those poisonous smokes have a chance to get close to you." In fact, even if Zhang Yu doesn't say it, these poisonous smokes can't cause them any trouble, after all, these poisonous smokes can only play a role after they come into contact with people, but even if they don't know that these smokes are poisonous, they have already used their spiritual sense to protect Zhang Yu Ying Jiang, and they will definitely not let those smokes get close to Zhang Yu, which is nothing more than letting them ignore this trap that may be the largest in the underground palace.

Well, Zhang Yu originally wanted to ask if he needed to go back and prepare some equipment, but now it seems that it is saved. After all, although he can also let himself not breathe the air here, and use the aura to provide himself with the consumption needed for his body, but not breathing does not mean that he is fine, Wang Lao's hand is obviously caused by contact with poisonous smoke.

After a small pause, the three of them stepped on the marble floor again. Obviously, the city gate should be the real entrance to this underground palace, but after entering the interior, its area began to open up more and more, and it was difficult for Zhang Yu to imagine how much manpower and material resources were consumed here to build this qiē.

"Interesting, this is either an underground palace built for himself by a guy who wants to be an emperor who is well fed, or it is really an emperor's mausoleum." Surprisingly, the three of them did not encounter any more danger along the way, and soon came to the steps at the end of the square. But in fact, the danger has always been with them, isn't that the poisonous smoke that has spread?

The reason why Ying Jiang made such an exclamation was actually because he saw the dragon-shaped stone platform in the steps, as well as the dragon-shaped cloud patterns carved on the surrounding railings. It is precisely because of this that Ying Jiang will say that this master is full of food. If the other party is not an emperor, the human and material resources spent on this dungeon are enough for him to do a lot of things. If it was an emperor, when he thought of those statues outside, Ying Jiang's heart sighed again, how many innocent people must be buried for the owner of this underground palace.

"Imperial Mausoleum? It shouldn't be possible, how could there be an imperial mausoleum in such a place? I've never even heard of it. Ying Jiang's words made Zhang Yu surprised, but Zhang Yu was more inclined to this should be a dream world built for himself by a guy who wants to be an emperor and wants to go crazy, after all, this was a relatively famous scenic spot a few hundred years ago, but I have never heard that there may be any emperor's mausoleum here, eh, however, it seems that this underground palace has not been discovered?

"Wouldn't it be better if you hadn't heard of it? It shows that the owner of this underground palace has really succeeded in hiding from everyone and built an underground palace here, but ......, if this is the case, I am afraid that this place will be ....... Ying Jiang chuckled, everything is possible, isn't this underground palace already built here? However, when he thought that the existence of this underground palace did not reveal the slightest news, Ying Jiang suddenly thought of the people who built this underground palace in the first place, and their fate was not likely to be any better, which can be seen by just looking at the statues of soldiers outside, but with the level of science and technology when this underground palace was built, if you want to build this underground palace, the manpower used will be tens of thousands, right?

Zhang Yu didn't hear the meaning of Ying Jiang's words, and he didn't care what Ying Jiang meant, at this moment Zhang Yu's mind was completely attracted by the huge complex in front of him, the owner of the underground palace here is a real emperor or a fake emperor Zhang Yu doesn't care at all, what Zhang Yu cares about is that since this underground palace has been so extravagant, can there be anything valuable in this underground palace? You must know that the values of many things are completely different from before, don't turn your head back and walk around, just find some spiritual metal, then it is called a big loss.

"There's nothing to make a fuss about, whether it was before or now, life is like a mustard." Wang Lao glanced at Zhang Yu, Zhang Yu didn't hear the meaning of Ying Jiang's words, but he heard it, Wang Lao really didn't know what to care about, no matter how he said it, it was all in the past after all, right?

"Huh! Are you talking about the soldiers? Zhang Yu was still a little distracted, but after hearing Wang Lao's words, he immediately reacted to what Wang Lao and they seemed to be talking about, and suddenly asked a little strangely.

"It's not just the soldiers, have you thought about the people who built the dungeon here? Even those soldiers are still like this, and the fate of those who were sent here to build the underground palace is even more conceivable, otherwise, I am afraid that the existence of this underground palace will not have been known for so many years. Ying Jiang smiled at Zhang Yu, and while sighing with Zhang Yu, he cautiously walked towards the stairs in front of him.

Don't look at Wang Lao and he are careless walking in this underground palace, but in fact, the vigilance that should be there is all, in this kind of place, who dares to be really careless? They had seen too many things about the overturned boat in the gutter, and it didn't take long for the three of them to carefully walk up the steps, and the accident suddenly happened again.

"Whew......!" It was as if a strong wind was blowing from the ground, just when the three of them saw that the last dozen steps could reach the door of the palace complex, a faint blue flame suddenly rose on the ground, and the flame was several meters high as soon as it appeared.
