Li Dan took the sapper shovel to dig the sealed soil, and the secret room behind the sealed soil was not dangerous.

It's just that there is no oxygen inside, wait a while, let the oxygen from the outside enter.

There are a large number of copper coins in the secret room, although they cannot be used directly.

I took these copper coins back and melted them, and kept a small amount for my collection.

Other copper coins were reminted and used as new currency.

The entire underground military fortress was explored and transported these materials to Honghou Mansion.

Liu Zhang roughly guessed that this land was once a place frequently contested by the Song, Lu, and Chu Kingdoms.

As long as you find the bamboo slip and see the content on it, you will know what happened back then.

The contents of the bamboo slips are priceless, and Liu Zhang decided to collect them.

Also consider how these bamboo slips were preserved more than 2,000 years later for historians to study.

These sealed chambers, except for the larger entrances.

There is also a dog-like entrance, which may have been deliberately left behind by those people back then.

It is convenient for individuals to take out the materials in the secret room, and it is not easy for others to find out.

"You try to dig this out, and we can enter the Chamber of Secrets from here."

This time, there was no need to drill the entrance like a dog hole, Liu Zhang stood behind Li Dan.

If the sapper's shovel can't dig up, then smash it with a hammer.

Li Dan dug the sealed soil very hard, and saw that there were stone bricks sealed behind the sealed soil.

"Although the sealed soil has been dug up, there are still stone bricks sealed here, and the shovel may not be able to dig it." Li Dan said to Liu Zhang.

"Then use a hammer to smash it open, there is a hammer in the secret room next door, I'll get it."

Liu Zhang went to the secret room next door, and then took out the hammer from the subspace watch.

Everything here has to be taken away and cannot be left to anyone else.

This time, not only did they rescue Chen Yun and them unharmed, but they also obtained a large number of treasures.

It was a surprise that the heavens favored him so much.

After a while, Liu Zhang brought two hammers.

"Let's open the bricks of this chamber together and see what's in there."

"Honorable Marquis, I'll call someone over, you can just watch from the sidelines."

Opening the secret room and sealing the bricks does not need to be handled by Liu Zhang personally.

Liu Zhang didn't insist anymore, with his current physical condition.

I can't beat it a few times, so I'd better leave this kind of strength work to them.

When the time comes, give them some rewards, which is a means for Liu Zhang to buy people's hearts.

Li Dan, they have contributed today, if they don't give them a little benefit.

Wouldn't that seem Liu Zhang stingy, and the sealed soil and bricks of the secret room were opened.

Several of the guards saw the black rumbling inside the secret room, and they also expected that there was a treasure inside.

Although most of it will become Liu Zhang's private collection, a small part will be distributed to everyone.

"Let's go in later, I don't know if there's any danger inside." Li Dan proposed to everyone.

Since you can't see the situation in the secret room clearly, if you rush in, you may get hurt.

After a while, Liu Zhang entered the secret room first.

"You guys wait outside for a while, I'll go check it out first."

He felt that the oxygen level in the chamber was about the same, and he went in first to collect some copper coins.

"Your Excellency, let's go in first. If there's danger, we'll block it first. ”

"There's no danger in there, take my word for it."

There are a large number of copper coins in the secret room, and a portion of them is collected and put into the subspace watch first.

Leaving some of them in the secret room, this is Liu Zhang's careful thinking.

The android robot explored other chambers and also discovered gold and copper.

If they know that there is a lot of gold and copper here, the news will soon reach the counties.

Even when it reaches Chang'an, Liu Che may find a way to keep the gold and copper for himself.

The main reason is that the war against the Xiongnu requires a lot of money and grain, and in recent years, they have tried various ways to obtain a lot of money and grain from rich merchants and nobles.

Liu Zhang also has to think about the future life of himself and his children and grandchildren, so he can't let outsiders know that there is a lot of gold and copper here.

"Your Excellency, it's too dark in the secret room. We didn't have torches or lanterns when we came here, so we had to send someone back to fetch the lighting first. ”

"I'll go first and take a look, I have a night pearl in my hand, which can play a role in lighting."

Liu Zhang took out the artificially made night pearl from his sleeve, and the night pearl emitted a light blue light.

"If you want to go in first, be careful. Call us immediately if there is a situation. ”

The chamber was dry, the space was large, and it was full of wooden boxes.

Liu Zhang opened one of the wooden boxes, which contained copper coins from the Warring States period.

There are copper coins in the shape of knife coins, shovel coins, round square hole coins, shell coins, cloth coins, etc., which are obviously the currencies of various vassal states.

The number of round square hole coins is the largest, as for why the currencies of other vassal states were not melted down and reminted.

The answer can only be known by finding bamboo slips, and Liu Zhang collected seven-tenths of the total amount of wooden boxes.

The rest were carried by the guards to the wagons and ox carts and transported back to the Honghou Mansion.

"Come in."

Let them come in and get these wooden boxes out, let them know that there is really no danger in here.

Even with three-tenths of the wooden chests left, the number of copper coins is quite staggering.

Hurry up and search the other secret rooms, this time it really made a lot of money.

"I'll just say, there's no danger here. There were no wooden boxes in these empty spaces, and they must have been moved by those people back then. ”

Liu Zhang's explanation was very reasonable, and everyone opened the wooden box and took a look.

A box full of copper coins with a slight patina on the surface.

"There is no danger in all these secret rooms, and strategic materials are stored here. Because of the war, they didn't have time to transport it away. ”

When everyone heard Liu Zhang say this, they all nodded in agreement.

Due to the intensity of the war and the possibility of a brief truce, they seized the time to move supplies.

The rest can only be sealed and picked up later when there is a chance.

"So many bronze coins, recast in the furnace, can mint a lot of half a tael."

One of the guards was excited, the more wealth Liu Zhang had.

It's also a good thing for them, and their income will be more stable.

These are all Liu Zhang's personal property, and treasures are found here.

He must not tell any stranger, lest some be concerned about his possessions.

"If you find these belongings today, you can't tell outsiders. When I go back, I'll reward you. ”

Even if Liu Zhang doesn't say it, everyone will be tight-lipped.

"You move it first, I'll go to the other secret rooms to have a look. I'll let you know if I find anything. ”

Liu Zhang's pressure space watch received a message from the simulator robot and found more copper coins and gold.

First to collect the gold and copper coins, the simulator robot also found the secret room where the bamboo slips were stored.

Bamboo slips are the last to see, and they are not worth much to most people anyway.

"Honorable Marquis, you have to go to other secret rooms, be careful." Li Dan handed Liu Zhang a knife.

"I will be careful and carry these things to the Honghou Mansion as soon as possible, so as not to cause any extraneous branches."

One chamber after another to explore, such as a wooden chest containing gold.

All included in the subspace watch, in the case of a wooden case containing copper coins.

Only three-tenths of the copper coins are left in the other chambers, and after exploring all the chambers, you will get gold and copper coins and copper artifacts.

Liu Zhang was shocked and delighted, there were too many of them.

The statistics of subspace watches came out, and the total amount of gold obtained was 559.6 kilograms, and 39.8 tons of copper was obtained.

Thirty-eight tons of subspace watches, and the food stored in other secret rooms is inedible.

"It's a shame that so much grain was found. I can't eat it at all, and it hurts to think about it. ”

Liu Zhang is really distressed, so much food.

There is also a last secret room, which is used to store bamboo slips.

This is what Liu Zhang wants the most, and these bamboo slips are priceless to him.

There may be some important events recorded on it that solve the unsolved mysteries of history.

The sealing earth and bricks of the chamber were opened, and after a while, he entered the chamber.

Bamboo slips are neatly placed on the wooden shelves in the secret room, and this secret room is smaller than the others.

Li Dan then came over to ensure Liu Zhang's safety.

"It's safe here, you come in." Liu Zhang said to Li Dan.

Li Dan followed the light blue light and walked over to Liu Zhang, who was holding a bamboo slip in his hand.

"Don't worry, this bamboo slip is not medicated. The light here is a little dim, so let's move these bamboo slips out first. ”

In the process of transporting it back to the Honghou Mansion, there can be no damage in the slightest.

"Remember, these bamboo slips are important to me. It cannot be lost or damaged. ”

Liu Zhang once again advised, even if the gold and copper coins were lost.

At most, for a while, bamboo slips are more valuable than copper coins and gold.

Although Li Dan was a little puzzled, the bamboo slips were not of much value to him.

It's just that Liu Zhang likes it, so he will be more careful to transport the bamboo slips back to Honghou Mansion.

This is one of the preferences of readers, and they attach great importance to the content recorded on the bamboo slips.
