Jiang Yongguang was right. If Yang Guo and his group hadn't opened the coffin, where had they all gone?

Could it be that what we discovered wasn't the main burial chamber, but just the tip of the iceberg of this ancient tomb?

With these questions in mind, Jiang Yongguang walked to the other side of the main burial chamber. He used the same method of throwing bricks to test the way, clearing out any mechanisms or traps before proceeding. He found another side chamber, symmetrical to the one before. This side chamber was also emptied of its burial goods, leaving nothing behind.

Jiang Yongguang mused, "According to the structure of a shaft tomb with a vaulted roof, there should only be three chambers here. Two side chambers and one main burial chamber, and we've already explored them all."

"That's not right. What about Yang Guo's tomb-raiding gang? Aside from the three corpses we found when we came down, where did everyone else go?" Old Wei asked, frowning.

"And don't forget the corpse that was pulled up from the Lock Dragon Well," I reminded Jiang Yongguang. "This tomb is definitely connected to the Lock Dragon Well, but there's no passage to the underground water in these three chambers. This can't be the entire tomb; there must be other mechanisms in the tomb."

After hearing us, Jiang Yongguang nodded in agreement. "You're right, there must be mechanisms in this tomb that we haven't discovered yet."

Xiao Liang stared at the seven coffins in the main burial chamber and speculated, "Do you think the mechanism could be these Seven Stars Doubt Coffins? After all, besides the Seven Stars Doubt Coffins, there's nothing else in the main burial chamber."

"Then why haven't these seven coffins been pried open?" Uncle Mei asked.

"It's possible the tomb robbers restored them, or maybe this mechanism can restore itself automatically," Xiao Liang said. "In any case, we can't find any other passages in the burial chamber besides these seven coffins."

Uncle Mei didn't want to risk opening the coffins. After all, no one knew what deadly traps might be hidden inside. He simply walked to the wall of the main burial chamber and tapped each brick, trying to find a secret passage in the wall.

But after tapping around, he discovered that all four walls of the main burial chamber were solid. There was absolutely no secret passage in the walls. Even if there was a secret passage, it could only be located somewhere else.

In the end, the few of us stood in the main burial chamber, staring at each other, our eyes all landing on the Seven Stars Doubt Coffins.

Jiang Yongguang said helplessly, "There's no other way. Let's open the coffins."

Xiao Liang also agreed. "I suspect the secret passage is hidden among these seven coffins."

Old Wei said cautiously, "Should we send for more manpower before opening the coffins?"

Jiang Yongguang shook his head. "We've already dispatched six brothers on this trip, all armed with guns. Wouldn't it be a bit too embarrassing to ask for more men from above?"

Uncle Mei and I exchanged glances, and finally hardened our hearts and agreed.

If we didn't open the coffins, it would be impossible to find Yang Guo, nor could we figure out the relationship between this Ming tomb and the ancient Shu tomb, let alone catch the White-Clad Immortal and rescue Sister Mei.

So we had to open the coffins!

After making up his mind, Jiang Yongguang waved his hand, signaling Uncle Mei, Xiao Liang, and me to step back. He and Old Wei, the two most experienced Xiaoling Guards, stood in front, bearing the main risk.

Da Yong's character was truly commendable. He always rushed to the front in such situations, never letting his brothers take risks. I admired him for this.

Old Wei was knowledgeable and had some understanding of astronomy. Before opening the coffins, he said, "The Big Dipper has seven stars, namely Tian Shu, Tian Xuan, Tian Ji, Tian Quan, Yu Heng, Kai Yang, and Yao Guang. The seven coffins on site are arranged in this order. Da Yong, which one should we open first?"

Jiang Yongguang was very familiar with the history of tomb raiding, but he didn't seem to be as proficient in feng shui. He didn't dare to make a decision on his own and said to Old Wei, "Old Wei, you're more experienced than me in astrology and feng shui. I'll listen to you."

Old Wei said, "Among the seven stars of the Big Dipper, Shu represents Heaven, Xuan represents Earth, Ji represents Man, Quan represents Time, Heng represents Sound, Kai Yang represents Law, and Yao Guang represents Stars. These seven stars each have their own duties and different functions. But looking at the Big Dipper as a whole, Yu Heng is the most dazzling, the brightest in the night sky."

"Then let's open Yu Heng?" Jiang Yongguang asked.

"Hold on, let me think some more." Old Wei didn't dare to act rashly. After all, opening the wrong coffin could cost lives.

Jiang Yongguang nodded gently. "No rush, take your time."

Old Wei said in a deep voice, "From the perspective of Ziwei Doushu (Purple Star Astrology), Tian Shu corresponds to Sirius, Yao Guang corresponds to the Broken Army Star, and Kai Yang corresponds to the Wuqu Star. These are all ominous stars, not suitable for selection, so they should be excluded first… Tian Xuan, Tian Ji, and Tian Quan are the most auspicious stars. The correct coffin should be among these three stars."

I didn't know anything about these astrological feng shui things and stood aside listening as if I were hearing a heavenly book.

Although Xiao Liang was a college student, college didn't teach her these feudal superstitions, so she couldn't understand either, and stood aside without saying a word.

After Old Wei and Jiang Yongguang analyzed for a long time, the two finally made up their minds—to open the Tian Xuan Star coffin first.

The two acted immediately, pressed down on the coffin lid, and pushed hard, ready to open the coffin!

However, at this moment, with a creaking sound, the coffin lid seemed to be tightly embedded in the coffin body, unable to be pushed or opened.

Old Wei frowned. "Damn, is the coffin lid nailed to the coffin body?"

In the Ming Dynasty, many coffins were nailed shut to prevent tomb robbing, making it not easy to open them.

Jiang Yongguang shook his head. "It shouldn't be. I checked around just now, and there were no traces of nails."

"Then is it a mortise and tenon structure?" Old Wei asked again.

The so-called mortise and tenon structure is like assembling a puzzle, joining the coffin lid and the coffin body together. Although no nails are used, the coffin lid can still be locked tightly, making it impossible to open it easily.

But this structure has a very unique shape that is immediately recognizable.

Jiang Yongguang examined it for a while, shook his head, and said, "It doesn't look like a mortise and tenon structure either. I guess the coffin lid is just too tight, and the two of us aren't strong enough."

With that, he waved to the other two Xiaoling Guards, signaling them to come over and help.

The two didn't hesitate and stepped forward, joining Jiang Yongguang and Old Wei, using all their strength to open the coffin.

Finally, with the combined efforts of four strong men, the coffin lid was opened with a creak. Jiang Yongguang quickly reminded, "Everyone be careful, watch out for mechanisms and hidden weapons in the coffin!"

Old Wei also shouted, "Hold your breath, there may be poisonous gas in the coffin!"

After saying that, the four people held their breath and continued to push the coffin lid forward.

As a result, just as the coffin lid slid forward, two sealing stones suddenly fell on the doors on both sides of the main burial chamber!

The change happened so suddenly that we didn't have time to react at all!

"Fuck!"

Uncle Mei exclaimed and instinctively wanted to run out, but before he could take two steps, the two sealing stones had completely fallen, blocking the way out.

The few of us were trapped alive in the main burial chamber!
