After hearing Zhuge Liang's words, Wu Liang immediately raised his head and looked above his head.

He saw a touch of golden color, which was a slightly curved metal strip about three inches long extending from the mountain at the top of the cave.

This metal bar is probably only as thick as Wu Liang's index finger.

The end gradually becomes slender, looking like a small tail growing from the mountain.

"Sir, is this gold?"

Seeing the golden color on the metal strip, Yu Ji's old eyes immediately lit up, and he quickly came over and asked with hope.

"Hard to say."

Wu Liang said noncommittally, and then said to Dian Wei, "Brother Dian Wei, please lift me up. I want to get closer for inspection."

"promise."

Dian Wei responded and stepped forward.

As soon as he bent down and stood up, he could easily carry Wu Liang on his shoulders, making Wu Liang's Tianling Cap almost press against the rock at the top of the cave.

Everyone has long been accustomed to Dian Wei's extraordinary power, so there is nothing to be shocked about.

Wu Liang also immediately began to carefully check the condition of the metal bar. After a few glances, he came to a conclusion and said to everyone with great certainty: "This is not gold, but ordinary bronze."

In fact, many people have some misunderstandings about bronze.

Based on the name "bronze", many people will assume that bronze should be cyan or green.

But in fact, the newly refined bronze is golden yellow, and its color is very similar to gold.

It is precisely for this reason that bronze has always been called "gold" or "auspicious gold" in ancient times. It is also based on this name that the archaeological community in later generations rewarded the Han Dynasty court with "a bounty of several thousand gold" and "Jiatun" if they disagreed.

There has always been another speculation about the record of "tens of thousands of jins of gold", that is, the "gold" rewarded by the Han Dynasty court may not be gold, and what the rich people who "have tens of thousands of jins of gold in their homes" are not gold, but may be bronze.

.

This speculation is actually not unreasonable.

After all, in the Han tombs excavated by later generations of archeology, no buried gold that could be measured in "ten thousand gold" was found. Even the "Haihunhou Tomb" with the largest amount of gold known to have been excavated before Wu Liang traveled through it.

Only over a hundred kilograms of gold were found in the tomb, which is far from the "tens of thousands of kilograms of gold in the home village" recorded in historical documents.

Originally, Wu Liang also felt that this speculation by later archaeological circles had some truth.

It was not until Wu Liang personally participated in the excavation of three Han tombs, namely the tomb of King Xiao of Liang, the tomb of King Guangchuan and the tomb of Marquis Haihun, that this speculation was finally overturned.

As a person who has experienced it, he can say with certainty that "tens of thousands of kilograms of gold in the home village" is really not a rare thing among the princes and princes of the Han Dynasty.

The reason why later generations of archaeologists did not find that gold.

Mainly because over the past two thousand years, most of the Han tombs have been robbed.

Lu Bu had robbed it, Boss Cao's generals Faqiu Zhonglang and Mojin Xiaowei had robbed it. Coupled with the frequent changes of dynasties, even some unknown little thieves must have patronized it, and I'm afraid it was more than once and more than one group of people.

So much so that in later generations, archaeological experts basically didn’t even have the soup, and they were lucky enough to find some missing scraps.

Anyway, no one knows better than Wu Liang why there is no gold in the tomb of King Xiao of Liang, the tomb of King Guangchuan and the tomb of Marquis Haihun.

Wu Liang also knew exactly why the tomb of Marquis Haihun sank to the bottom of the water and why it left some scraps for later generations, making it the Han tomb with the largest amount of gold discovered by archeology in later generations.

That's why.

What Wu Liang knew better was that he and the Hu army were really not suitable to leave their names in history, so it was perfectly fine to ask them to touch Captain Jin and General Faqiu Zhonglang.

As the biggest beneficiary and instigator, Boss Cao should shoulder the blame, but Wu Liang would not take the blame anyway.

I thought too far again.

Wu Liang quickly shook his head and turned around.

But Yu Ji then asked reluctantly: "Sir, even if this is bronze, I'm afraid it can't be ordinary bronze. Otherwise, how could the color be so fresh?"

"The old gentleman really has some knowledge. He finally got to the point this time."

Wu Liang glanced at Yu Ji approvingly, nodded and said, "Bronze is a metal that is easily corroded, so some of the older bronzes we usually see usually have a layer of bluish-gray or bluish-green oxide layer.

It is basically impossible to maintain the golden color of bronze when it is first refined."

While speaking, Wu Liang looked at this small piece of bronze, and pointed at the coffins with human figures on both sides of the cave, and continued: "In the same environment, the bronze nails used in those coffins suffered quite a lot.

It is severely corroded, but this small section of bronze strip is still intact. This is the most strange thing and the most worthy of our further investigation."

"Brother Youcai said this, he must have seen the clues!"

Zhuge Liang said immediately, his face full of admiration and expectation, and he almost took out a small notebook and started taking notes on the spot.

"No."

Wu Liang shook his head again and said without hesitation, "As far as I know, apart from the vast universe, there is no way in nature that can prevent the oxidation of bronze, especially in such an environment, so

, I can’t explain exactly what is going on.”

"..."

The scene suddenly became cold, and no one could answer the question and could only remain silent.

Wu Liang stopped talking nonsense, and with Dian Wei's help, he got closer, and then stretched out his gloved hand to gently touch the small bronze strip.

The texture is hard.

It is definitely made of bronze.

But this small piece of bronze strip does not look like a decoration artificially embedded in the mountain. Not only does it not have any decorative patterns, the shape does not look beautiful at all. On the contrary, it comes from the way the rocks around this small piece of metal strip are cracked.

Look, it looks more like it was forced out of the mountain.

Considering that the cave Wu Liang and others are currently in is located in the middle and lower part of the mountain, there are many caves with higher altitudes above.

Wu Liang has reason to suspect that this small piece of bronze may have been caused by some bronze objects being placed in the upper cave, as was the case in later generations when the upper floor was renovated and penetrated through the floor to the lower floor. This is why such a situation occurred.

However, this still cannot explain why this small metal strip does not show any oxidation phenomenon...

So Wu Liang reached out and grasped the small metal strip, and then slowly pulled it downwards, hoping to further understand the structure and condition of the small metal strip hidden inside the mountain.

The result was... not moving at all.

From this point of view, this small bronze strip was just as he guessed. It was not a small independent individual, but involved something inside or on the upper level of the mountain.

However, Wu Liang did not intend to use force on him.

Whether it is for protection or research purposes, he does not want to carry out some irreversible destructive excavations here without understanding the situation.

at this time.

"Wu Youcai, there is movement!"

Bai Jingjing suddenly said with a serious expression.

"Is that the low moan you heard before again?"

Wu Liang felt nervous and asked subconsciously.

"no."

Bai Jingjing shook her head and said, "There is movement within the mountain. Just now as you pulled this small piece of bronze strip, I heard some extremely slight noises. This noise did not just come from a certain place, but was like

A line generally spreads through the rocks above us, continuing deep into the cave."

"Continues to the depths of the cave?"

Wu Liang's brows furrowed.

He understood the meaning of Bai Jingjing's words, but he couldn't figure out what it meant.

Could it be that this small piece of bronze is actually just an inconspicuous thread, directly involved in some unknown thing deep in the cave, and may it affect the whole body?

This undoubtedly made Wu Liang more confused.

He was no longer sure whether he should continue to pull on this small piece of bronze, fearing that if he accidentally pulled it, it would cause a big problem and eventually bury him and the backbone of the Hu army under this mountain mausoleum.

He pondered like this for a moment.

"Dianwei, let me down."

Wu Liang finally chose to put this small piece of bronze aside for the time being, and no longer acted rashly. He first fully explored the situation in the cave before making a decision.

…

With this big or small puzzle, the Hu army continued to go deep into the cave.

As a result, Wu Liang encountered another suspicious situation after walking about less than thirty meters.

I saw a small golden bronze strip protruding from the lid of a coffin with a human figure on the right side of the cave.

It is different from the small bronze strip before.

This small piece of bronze can be very certain to have come out of the coffin.

Because wooden coffins are different from rocks, when a hole is forced out of the wood, the wood thorns and wood residue produced by the damage to the wooden structure will not scatter directly like brittle hard rocks, but will be connected to the coffin lid like a direction.

Lift up.

"this……"
