Chapter 770: Underground Grotto

"What are you saying?"

Liu Zheng was startled.

Wu Zhen nodded, his face calm: "Below is a massive palace complex, or rather, one could describe it as a grotto... it could accommodate hundreds of thousands!"

Shock!

Astonishment!

Everyone was taken aback.

Hundreds of thousands of people?

How big would that be?

Previously, Wu Zhen had predicted that this Tomb Cluster should be very large, larger even than this Wangchuan, and while others had doubted him, at this moment...

Liu Zheng narrowed his eyes slightly: "Mr. Wu means..."

Wu Zhen bowed and said: "We can take our troops, and even all our accompanying personnel, entirely into the underground tomb! When that time comes, let alone Qiao Yuan failing to find us, even if they did find us, if they wanted to enter, heh..."

Catching a turtle in a jar!

Everyone's eyes lit up.

"How long until we can enter?"

Liu Zheng also became excited.

This was the best Method!

Wu Zhen replied: "My Lord, we can open dozens of passages overnight today! The passages are at most three zhang from the surface; even those who cannot swim can enter! If we continue without stopping, everyone can enter within seven days!"

Everyone was overjoyed to hear this.

Liu Zheng was even more excited, saying: "Then what are we waiting for? Listen to my orders: defensive battle, shift to conservative, start organizing people to enter the tomb one after another!"

"Yes!"

And so.

Suddenly, the attacking side also turned conservative, and the defending side also turned conservative.

The battle situation became less intense.

And the people here were also informed that everyone might enter the Tomb Cluster!

All at once, these two hundred thousand people were shocked.

The soldiers were fine; they did whatever their commander said, for military orders were like mountains.

But these wealthy men who had followed Liu Zheng here had different thoughts. Some were happy, while others were afraid. They were happy that they were fortunate enough to participate in a tomb that might unearth the Imperial Jade Seal, but they were afraid that in this business of tomb raiding, if one were not careful, would they lose their lives?

And this meant going underground...

Who wouldn't be afraid?

But.

They had no other Method.

The Liaodong Army was fighting too fiercely. Did they not know how many people had died these past few days? Many among these people had already retreated to Taixi Stockade. But even if they retreated to Taixi Stockade, what could they do? If this Liaodong Army really took Wangchuan Valley, once the Great Tang remnant army arrived, Taixi Stockade would likely not be peaceful either... It would be better to follow Vice Minister Liu...

Burrow underground?

Good!

Then we burrow!

The ideological work didn't take long; everyone agreed.

In one night, Wu Zhen's side got it done. It seems these tomb raiders brought by the Prince of Wei were quite professional.

Thirty passages!

All were beneath the river surface. To what extent had the weather turned cold by now? If they smashed the ice on the river, it would quickly freeze over again after a while...

The ice layer was already very thick.

To go down, they had to seize these few days; otherwise, they feared the weather would get colder and the ice would be too thick for them to even smash through!

Liu Zheng himself was also eager to try.

To put others at ease, he decided to risk it himself and set an example.

Thirty passages, three hundred people could go down at once, because they had only made three hundred sets of "Diving Suit"s.

"Vice Minister Liu, be careful..."

The Prince of Wei, the Prince of Yong, and Tie Mucheng all urged him.

Liu Zheng smiled: "I will go down first, you all follow later!"

"Good!"

Liu Zheng followed behind Wu Zhen, and Wu Zhen gave the order.

Immediately, someone chiseled through the ice on the river surface. They had long memorized the locations by heart. Once the two-foot-thick ice layer was chiseled open, one could see the river water murmuring below...

Cold!

A chill couldn't help but rush up, making many people terrified.

"Jump!"

Although Liu Zheng knew Swimming, this was his first time entering the water in such terrifying and harsh weather.

Splash!

Despite wearing the "Diving Suit" made of animal fur, a bone-chilling cold instantly enveloped Liu Zheng. Most crucially, his face was instantly frozen stiff by the icy water. But actually, it was fine; as long as it was flowing water, the temperature wouldn't be that low. As he sank further down, the situation got better and better. You would find that after the initial bone-chilling cold, the river water below actually became warm...

Suddenly, he felt much more comfortable.

"This way!"

Wu Zhen pulled Liu Zheng.

Sure enough.

A large hole in the riverbed over there had already been cleared, wide enough to accommodate two people entering.

But they still went in one by one.

After entering this passage, Liu Zheng was incomparably shocked. This passage was hidden at the bottom of the river, yet it was able to keep the river water out; naturally, many winding designs had been incorporated. Sure enough, just after coming in, he lost his sense of direction, following Wu Zhen as they turned left and right, at times ascending in the water, at times running on the ground.

The damp passage exuded an ancient aura.

There was no light here, so when the Fire Tinder was lit, it meant that the river water that had surged in had already been drained away to who knows where.

"This way, my lord!"

While Liu Zheng was marveling at the wisdom and the supernatural craftsmanship of the ancients, Wu Zhen had already led him forward for some distance.

Finally.

He arrived at this Underground Palace Complex.

At this moment, he could no longer hide his shock and let out an exclamation.

At this time.

He and Wu Zhen were actually standing on the edge of a cliff; looking out, the vast space made it impossible for Liu Zheng to close his mouth.

Shock!

Apart from shock, Liu Zheng could find no other words to describe everything that appeared before his eyes.

This entire underground architectural complex was arranged in a regular shape, with huge Stone Pillars supporting this awe-inspiring space; if one had to call this a cave, then this cave was far too large and far too magnificent. The cave walls, the cave ceiling, and the Stone Pillars all bore evenly spaced chisel marks that seemed to have been intended as decoration by the ancients; these chisel mark patterns were uniform, which was mind-boggling.

Underground Stone Grotto!

The Underground Stone Grotto where Liu Zheng and Wu Zhen were currently located, at a single glance, could be seen to be laid out in the shape of the Big Dipper, with an area conservatively estimated to reach several thousand square meters...

Grand!

Domineering!

Opulent!

Liu Zheng's shock was not without reason. Because from the perspective of a modern person like him, this Underground Stone Grotto was still hard to believe. Those chisel marks, whether decorative or carrying some sort of significance, would likely require modern high-strength intelligent mining equipment to achieve such an effect...

And looking at the entire layout of this grotto, it was even more in line with modern principles of mechanics; the interior height was about fifty meters, the cave entrance was rectangular, the cave walls were steep, the top was at a forty-five-degree angle, and the shape looked very much like an "inverted bucket," with stone steps leading to the bottom of the cave. Each cave had two to five shark-fin-shaped Stone Pillars for support, the thick supporting Stone Pillars were integrated seamlessly with the cave ceiling, the cross-sections were all iron-shaped, and the larger ones would require ten adults to wrap their arms around.

My god...

What kind of place is this?
