Tang Qishan and several people got into the passage behind the boulder from the gap that was blown up, the passage was irregular, inclined downward, only more than one meter high, and several people couldn't stand up, so they could only move forward with their waists. After walking for more than ten minutes, they came out of the narrow passage, and the space instantly became larger, and several people were out of breath when they straightened up. After walking for so long and going deep into the mountain, there is a little lack of oxygen.

"Look, there's a stone gate!" Erin gasped, pointing to a stone door in front of her.

"Did you notice something wrong?" Tang Qishan asked Zhang Tiancheng.

"Huh?" Zhang Tiancheng wondered.

"The boulder outside obviously didn't fall at the mouth of the passage, this passage leads directly to this underground tomb, although it doesn't lead to the inside, what does it mean?" Tang Qishan asked rhetorically. Several people also felt a sigh in their hearts.

"Could it be that this is a thief hole?" asked Zhang Tiancheng uncertainly.

"It's not like a robbery hole, it's supposed to be an escape passage for the workers who built the mausoleum, but it should have been discovered, so the passage was sealed with a boulder, otherwise the passage should have led directly to the outside of the mountain, not in the crack, which was also formed by the collapse of the mountain. Lin Zhengfeng said.

"Then what are you waiting for, open the door?" Zhang Xiaoqiang was impatient.

"Open, what to open? Now that the passage here has been discovered, as soon as the door of this tomb is closed, it is obviously a broken dragon stone, who can push it open?" Erin was anxious about Zhang Xiaoqiang's IQ.

"What a fart, what about blowing it up with explosives?" Zhang Xiaoqiang looked at Zhai Qinglin.

"No! This tomb gate is surrounded by regular strips of granite, which are large and heavy, and the explosives will blow up this place if they are too powerful, but they will not be blown up if they are too powerful. Zhai Qinglin said.

"This doesn't work, that doesn't work, you said that the ancients didn't have any high technology, and they could transport this well-behaved big stone in, how can we be regarded as masters in the world, and we can still be suffocated to death by urine?" Zhang Xiaoqiang said speechlessly.

"Yes, fatty! Erin patted Zhang Xiaoqiang's head and smiled.

"Erin, what can be done?" asked Tang Qishan.

"This mausoleum is built dozens of meters underground, and it is inside the mountain, and there is no passage to connect the emperor's mausoleum above, so how do they transport the stones in?"

"Ouch! beauty, you are so smart!" Zhang Tiancheng patted his head and praised Erin.

"What?" Zhang Xiaoqiang looked at a few people with a blinded expression.

"I just finished praising you, and you became a pig's head, since they can't transport it in, it must be mined on the spot, and if the passage we came in just now is really an escape passage built by workers, it proves that there are often worker activities here, and since there are worker activities, then this must be a place where stone is mined." Erin laughed at Zhang Xiaoqiang's IQ.

"Then what can it prove?" Zhang Xiaoqiang still didn't open his mind, and the rest of the people couldn't hold back their laughter.

"Stupid, since this is a site for quarrying stones, generally solid rock masses are used as materials for building tombs, and they will definitely hollow out weak places, this tomb door is obviously closed after discovering this escape route, you look at both sides, after geological movements, cracks have appeared on both sides, and if you look for them along the cracks, you will definitely find a place where you can explode with good control and measurement. Erin said.

"I didn't expect you to be very good-looking, but your brain is very useful. Zhang Xiaoqiang said.

"What are you talking about?" said Erin, glaring at Zhang Xiaoqiang.

"Okay, let's get down to business first, and let's split up and look along the cracks. Lin Zhengfeng said.

Several people split into two groups to search for the cracks on both sides of the tomb door.

"Come here!" Lin Zhengfeng shouted.

When a few people heard the sound, what they saw was a five-meter-square pool, and water was constantly coming out of it, and it was not artificially built, but like a flood formed by a crack in the mountain.

"What's going on?" Zhang Tiancheng asked.

"Fujian Linhai, this is the interior of the mountain, and we all the way in are diagonally down, I estimate that the location here is already below sea level, and here is the crack, the mountain is relatively weak, this waterhole should be squeezed up by groundwater pressure. Tang Qishan said.

"You mean to explode from here?" Zhang Tiancheng asked.

"No! This is supposed to be groundwater, if it explodes, it will cause the groundwater to back-up and then erupt, and none of us will be able to escape, we will be crushed to death in this crack by the pressure of the water. Zhai Qinglin looked at it and said.

Several people shook their heads, obviously not thinking simply, even if the mountain was blown up, they might not be able to enter the tomb, which was already some distance from the stone gate, and there was no guarantee that the place where the explosion was blown up was just the tomb.

"Since this is living water, there is only one way in front of us, dive in and see if it can be connected to the tomb. Lin Zhengfeng said.

"Crazy! Not to mention how cold the water is, even if you go down, do you know how deep it is? Is the bottom connected to the tomb? What if the structure below is unstable and blocked inside?" Zhang Xiaoqiang shook his head.

"What do you think?" Lin Zhengfeng looked at a few people.

"Now that I've arrived at the door of the tomb, if I can't find a way to get in, it's for nothing, and Li Sheng doesn't have a lot of time, so I think I can take the risk and give it a try. Tang Qishan said.

"I'm okay! I'll follow him wherever he goes, and if he's dead, I'll have to collect his body." Erin shrugged.

"Don't look at me, what are you looking at me for?" Zhang Xiaoqiang saw that several people were looking at him.

"Dead fatty, if you don't dare to go, go back, there are not many more of you. Erin said dismissively.

"Little girl, don't provoke me!" Zhang Xiaoqiang said angrily.

"Do you use it?" said Erin, rolling her eyes.

"Damn, just go down, can a big living person be choked to death by a mouthful of water?" Zhang Xiaoqiang said ruthlessly.

"Okay, I'll go down first, and if there's a way, I'll come up and inform you." Lin Zhengfeng said.

"I'm a soldier, I'm good at water, and I've had stress training. Zhai Qinglin said indifferently.

"Okay! We'll be waiting for you. Lin Zhengfeng nodded.

Zhai Qinglin threw down his backpack with capable movements, took out a waterproof flashlight, took off his mountaineering clothes, took a deep breath and planted himself in the pool. Several people were nervous, hoping for good news.

After ten minutes, there was no movement underwater, and Zhang Tiancheng was anxious.

"Why haven't you come up yet? It's been ten minutes, who can hold it for so long? Is something wrong?" Zhang Tiancheng said anxiously.

"Probably not! He's very sensible, and if he doesn't, he'll come up. Lin Zhengfeng said.

"But......" Zhang Tiancheng wanted to say more, but saw a light underwater.

"Come up!" Tang Qishan shouted.

"Whew......" Zhai Qinglin got out of the water and took a sharp breath, then looked at a few people and nodded.

"It's connected to the burial chamber, I've been inside, and there's a pool in it. Zhai Qinglin said.

"Also!" Zhang Xiaoqiang was also excited, and the rest of the people were relieved.

"Okay! Get into the water!" Lin Zhengfeng said.

Several people threw down their heavy supply backpacks and dived into the pool one by one.

Zhang Tiancheng was the last to come out of the water and let out a sigh of relief, what everyone didn't expect was that Zhang Xiaoqiang's water nature was actually very good, and it was estimated that he was timid.

After several people came out of the water, they all looked around at the tomb with flashlights. It was a hall, and the pool from which they came out was under an altar, and above the pool there was an outlet, from which water was constantly flowing, and behind several people was a tomb passage, judging by the direction, which led to the previous tomb gate. It was dark and there was no light.

"It's wrong! It's a little stuffy!" Zhang Tiancheng said.

"Oh no! The space here is all confined and there is no air circulation. Lin Zhengfeng said.

"Then what should I do? Get out of here, or I'll have to suffocate here. Zhang Xiaoqiang said.

"I'll have to open the door to the tomb. Lin Zhengfeng said.

"How do you open it? Tang Qishan said.

Zhang Xiaoqiang, you go out and bring in the explosives in the remaining backpack, the air here is thin, there are many of us, and we can't support it for long. Lin Zhengfeng said.

"I'll go! It's easy to blow it up from the inside, I'm measured. Zhai Qinglin didn't talk nonsense, and jumped directly into the pool.

Waiting for Zhai Qinglin to come in again, he took the explosives and flashlight, and walked to the graveyard behind him.

With a muffled sound, I felt that the entire space shook, and a lot of sand and dust fell, and the frightened few people looked at the top of their heads nervously, for fear that Zhai Qinglin would be blown up, so none of them wanted to get out alive.

"Rest assured, this mausoleum is inside the mountain, and the top is an arched structure, which is very strong, not an ordinary masonry dome, and there is no quicksand. Lin Zhengfeng looked at it and said.

"Huh" a mountain wind poured in from the tomb door, both sides of the tomb door originally had designed oil lamps, the lamp base is carved and chiseled as a whole, and the magic axe is wonderful. The oil lamps ignited when they were in the wind, and they were lit one after another from both sides of the tomb door, which looked a little weird, and there were also oil lamps on the walls around the hall, which were also lit immediately.

"There's air, there's white phosphorus on this wick. Tang Qishan looked at the oil lamps lit up around him and said.

A few people extinguished the flashlight, and the hall was clear at a glance, this catacombs were medium, not big. At the other end of the hall is a corridor, there is an ear chamber on the left and right sides, and this tripod is placed on the altar above the pool, and below the altar is a large square pit, and there are many white bones in the pit.

"This is supposed to be a sacrificial altar, and the pit is full of animal bones. Erin said, she was well-versed in medicine and could tell at a glance that there were no human bones in the pit. As soon as Erin finished speaking, she heard a "click" sound coming from the pit, and then the bones of the sacrifices were all shattered and turned into powder in an instant.

"What's going on?" Zhang Xiaoqiang looked nervous and hid behind Lin Zhengfeng.

"It's been so long that the bones have oxidized into powder when they meet the air. Erin explained.

"It scared the hell out of me, I thought there was something unclean. Zhang Xiaoqiang said.

"Not necessarily. Lin Zhengfeng said.

"This is a sacrificial pit, there is no coffin. Go ahead and take a look. Zhang Tiancheng looked around and said.

"This sacrificial tripod is a good thing!" Zhang Xiaoqiang's eyes lit up.

"Don't mess around, I warn you, and if you get into any trouble, I won't care about you. Lin Zhengfeng admonished.

"Just look at it, I can't move this ding, I won't move it, it's a killer!" Zhang Xiaoqiang said.

"Wait, how can there be a bronze tripod on this altar?" Tang Qishan suddenly asked.

"Is there something wrong?" Zhang Tiancheng asked.

"This Zhu Yunwen is the emperor of the Ming Dynasty, and the bronze tripod in the tomb is only prevalent in the Spring and Autumn Period and before the Spring and Autumn Period, where have you heard that the Ming Dynasty's mausoleum excavated the tripod?

"This ......" Zhang Tiancheng didn't know.

"Isn't this tomb the one above?" Zhang Xiaoqiang pointed to the top of his head.

"Although the burial goods after the Ming Dynasty are very different according to the identity of the tomb owner, in general, they are some gold, silver, jade, jewelry, ceramics and other things, where have there been bronzes?" Tang Qishan continued.

"The feet of this bronze tripod are inlaid on the altar, which is very consistent, not placed later, so this tomb is not a tomb of the Ming Dynasty, but may be a tomb of the Spring and Autumn period or before the Spring and Autumn Period?" Zhang Tiancheng said.

"I don't know, I just go in and have a look. Tang Qishan looked at the road in front of him.

The slight flickering lights in the tomb made this underground palace confusing.
