After hearing Miao Dabao's words, Cao Lu was scared and regretted his recklessness just now. Yan Ning patted his shoulder to show comfort.

Zhuang Xiaoya looked at the fire in the pit and couldn't help but ask: "The fire below is so big now, what should we do? Will we wait until the fire is extinguished?"

Wang Tianci shook his head and said, "No, there are also some requirements for entering the tomb. After that, we have to wait three days. We must enter the tomb tonight."

"I'll pick up some water to put out the fires," Cao Lu said.

Miao Dabao hurriedly called Cao Lu: "Don't be stupid. The fire of Fire Dragon Oil cannot be extinguished with water. You just used water to extinguish it because the fire was too small and it was not stained with real Fire Dragon Oil."

"Then..." Cao Lu hesitated.

"Fill the tomb soil back. Without air, the fire dragon oil cannot burn." Wang Tianci said.

Yan Ning said in confusion: "But we still have to dig the pit after all."

"Let's talk about it then, let's put out the fire first." After Wang Tianci finished speaking, he walked aside to sort out the equipment. Yan Ning and Cao Lu looked at each other, and helped to pick up the shovel and fill in the tomb soil outside the pit.

Sure enough, the fire ignited by the fire dragon oil quickly went out. Yan Ning wiped the sweat from his head and said to Wang Tianci: "Okay, let's go down."

For safety reasons, Zhuang Xiaoya, Cao Lu and Miao Dabao stood outside the pit, and Yan Ning and Wang Tianci followed the rope to the tomb pit more than ten meters deep.

"What should we do now?" Yan Ning asked, and he also felt a little afraid of the tomb soil under his feet.

Wang Tianci, wearing gloves, reached out and gently dug up the tomb soil at the bottom of the pit. Yan Ning soon saw a huge brick buried in the soil.

"This tomb brick has not been destroyed, and the fire dragon oil inside cannot flow out."

After Wang Tianci finished speaking, he took out a bottle from his backpack. Yan Ning saw it and said speechlessly: "What are you doing with a bottle of vinegar when you are in the tomb?"

"Look at it."

Wang Tianci opened the vinegar bottle and poured it into the cracks on the edge of the tomb bricks bit by bit. He saw that there was a trace of white smoke coming out around the tomb bricks, which was corroded at a speed visible to the naked eye!

"Is the bottle filled with sulfuric acid?" Yan Ning said in surprise.

"It's vinegar," Wang Tianci said while pouring vinegar, "This tomb brick is made of rammed earth, mixed with glutinous rice juice and boy's urine, which is stronger than concrete... Of course, it's just the whole, its outside is relatively fragile, and it is filled with fire dragon oil. Cao Lu broke it just now, and the fire dragon oil was sprayed out."

"Then the function of this vinegar is..."

"I don't know the principle either. I only know that one thing is used to drop another. This tomb brick may not be blown open with a bomb, but after being poured with thick water, it is as fragile as tofu."

As he spoke, the tomb brick under Wang Tianci's feet had completely corroded. Wang Tianci gave up his birth and asked Yan Ning to make the tomb brick.

The workmanship of tomb bricks is not as good as that of today. The joints are uneven. Yan Ning put on gloves and easily picked out the tomb bricks and placed them aside carefully, for fear of breaking them and causing fire dragon oil.

When Zhuang Xiaoya saw Yan Ning safe and sound, she immediately breathed a sigh of relief: "Come on!"

With the experience of the first tomb brick, Yan Ning and Wang Tianci quickly dug out three tomb bricks in one breath. At this time, the gap was enough for one person to enter. Yan Ning looked down and it was pitch black, and he didn't know what was underneath.

What made him feel magical was that the thousand-year-old tomb was opened for the first time, but there was no smell of rotten smell, but a faint sandalwood.

"The emperors of the Five Dynasties and Ten Kingdoms like to stuff jade into their butts after death. On the one hand, it is used to prevent corrosion, and on the other hand, it can ensure the fragrance of the tomb." Wang Tianci said lightly.

"Damn!" Yan Ning almost vomited out after hearing this, and quickly shook his head, not wanting to smell the smell again.

Wang Tianci said again: "But what you smell is sandalwood, which means there are many objects made of sandalwood in this tomb."

Yan Ning felt that he was teased by Wang Tianci, and said depressedly, "Why didn't you say it earlier! I'm so angry that my uncle has never heard of this sentence?"

"I don't have an uncle." Wang Tianci said lukewarmly.

"Damn!" Yan Ning raised his middle finger to Wang Tianci speechlessly.

Cao Lu threw down the cold fireworks from above, Yan Ning took them, pulled them away, signaled Wang Tianci, and threw them directly into the tomb.

The cold fireworks dripped with dazzling light and fell rapidly, and finally fell to the ground, rolled a few times, slowly extinguishing.

"What did you see?" Wang Tianci asked.

"It's about twenty meters below." Yan Ning replied.

Wang Tianci shook his head, turned on another cold fireworks and threw them down.

This time Yan Ning saw clearly that there was a huge deep pit in the southwest of the tomb.

Hundreds of white bones are buried in the deep pit!

"What is that?" Yan Ning sweated coldly on his back.

"Hundreds of people were buried in the pit." Wang Tianci replied.

Zhuang Xiaoya threw down the rope from above, and everyone went down the tomb along the rope.

When Zhuang Xiaoya landed on the ground, she felt a chill, and she couldn't help but shivered and leaned into Yan Ning's arms.

"Don't be afraid." Yan Ning patted Zhuang Xiaoya on the back.

"It's chilly. Wasn't this tomb sealed? How could there be a yin wind?" Cao Lu couldn't help but say.

Miao Dabao explained: "The Feng Shui bureau in ancient times paid attention to the three points of Feng Shui. A tomb that was not ventilated was definitely a bad tomb."

"Then what other holes should we dig? Just come in directly through the ventilation port." Cao Lu said in confusion.

"The ventilation opening is called the Xu Tai. It is the place where the entire tomb hides wind and gathers energy. In ancient times, the empty position was as big as a tomb chamber and was often used by tomb robbers. Later, the tomb was modified and the empty position had been changed to only a few inches in size. Not only could it not be as big as a person, but it also had many mechanisms. If we find the empty position, we would have to die forever when we came in." Miao Dabao said.

Cao Lu sighed and glanced at the thief hole in his head. The twenty-meter drop had turned the thief hole into a small spot of light, which was particularly prominent in the darkness.

Wang Tianci turned on the flashlight and swept the entire tomb chamber, and found that the place where everyone was placed in the tomb was just the front hall of the tomb.

The civilian tombs adopt the design of living houses, which are generally divided into front halls, back rooms and ear rooms. Although the imperial tombs are luxurious, they cannot be separated from this logical structure. They only add many side halls, front halls, etc. to them.

Yan Ning turned on the flashlight and went with Zhuang Xiaoya and Miao Dabao to check the burial pit of a hundred people, while Wang Tianci turned around with the flashlight to check the gate of the front hall.

Cao Lu looked around and felt that it was safer to follow Wang Tianci, so he followed Wang Tianci.

The two stopped in front of a huge stone door. Wang Tianci observed left and right, touched the stone wall from time to time, and looked down from time to time to time. Cao Lu asked, "Is this the gate to enter the tomb?"
