Seeing this situation, Wu Liang did not dare to let down his guard.

He carefully came to these corpses to check the situation.

Soon he discovered the cause of death of these corpses. They were also dead because their heads were penetrated from top to bottom by an unknown sharp instrument. They were not much different from the corpses he had found before.

Similarly, Wu Liang also found some chisels and craftsman's tools around them.

It can be seen that these people are the same group as the corpses from the Spring and Autumn and Warring States periods found along the way.

As for what exactly was this group of people harmed by?

Wu Liang first eliminated the "water ghost" that had just attacked him.

Although the "water ghost" is relatively powerful, it doesn't feel like it can pierce a person's skull with one blow. After all, the human skull is one of the strongest bones in the human body. A direct blow can

The force required to pierce cannot be underestimated.

Moreover, the height of the "water ghost" is relatively limited, almost a head shorter than him. Even if he jumps up, he may not be able to attack the heads of these corpses from top to bottom.

Furthermore, the "water ghost" just used the chisels left behind by these corpses.

The chisel tip was flat, and the holes left on the heads of these corpses were obviously caused by sharp weapons such as spears. There was obviously a big difference between the two.

the most important is.

These corpses seemed to have died within a relatively short period of time. Even if the "water ghost" did have a special weapon in the past, and his jumping ability and strength were also amazing, it seemed difficult to do this.

unless.

There is more than one "water ghost" here...

But this possibility doesn't feel great. If there were more than one "water ghost" here, it would be impossible for him to meet him until here, let alone escape from the river and successfully cross the river to the other side again.

So Wu Liang is still more inclined.

These corpses encountered something more terrifying than the "water ghost", and this thing had extremely powerful explosive power. In front of it, these people had no power to resist at all, and even escaping was a luxury.

And this thing.

It is most likely related to the dark door in front of them. If someone had not deliberately placed these corpses, their state of death was undoubtedly far away from this door...

Take a deep breath.

Wu Liang finally came to the door with great caution.

He discovered that the black color was not actually the original color of the door. It was just a layer of black paint. It was unclear whether it was used to prevent rust or for decoration.

There is a hint of metallic color in many places on the door. If you look closely, it seems to be bronze that was more common in the Spring and Autumn Period and the Warring States Period, but it is not exactly the same. It seems to have other alloy components, like the chisels Wu Liang discovered before.

, and there was no particularly serious rust.

In addition, there are some exaggerated animal patterns cast on the door.

The heads, horns, eyes, noses, mouths, claws and other parts of the animals can be clearly seen in the patterns. Because of his professional advantage, Wu Liang can also distinguish some of the animals, including deer, cranes, and horses. These are all

Animal carvings with good meanings were popular decorative patterns among the people during the Spring and Autumn Period and the Warring States Period.

besides.

Wu Liang also saw a small and irregular circular groove in the center of the gate.

The groove is about two centimeters deep and only five centimeters in diameter.

There are also some uneven lines engraved in the grooves, but these lines do not seem to form any symbolic pattern. They just go around and finally connect four small holes with a diameter of no more than one centimeter.

together.

It was pitch black inside the four small holes, and the dim light of the Suihou beads could not fully shine through.

Although Wu Liang didn't know what the small circular groove and the four small holes in the groove were used for, he vaguely felt that this might be the key to opening the door. The principle is similar to

Lock.

After all, wooden locks installed on wooden frame buildings were discovered as early as 3,000 BC in the Yangshao Cultural Site of the Chinese Dynasty.

And if this was a public tomb, it would be no problem for Lu Ban, as the master craftsman, to come up with a set of sophisticated locks to protect his tomb.

But if this thing is really a lock, it will need a corresponding "key" to open it.

Wu Liang definitely doesn't have the key.

I don’t even have any clues as to where to look…

Under this situation, Wu Liang first pushed the door hard.

Sure enough, it didn't move at all.

There is no need to try to pull it. There is no such thing as a pull ring on the door. There is not even a place to start, so how can it be pulled open?

As for the possibility of sliding doors, Wu Liang quickly ruled it out.

"..."

After pondering for a moment, Wu Liang looked back at the corpses arranged in an irregular fan shape behind him.

These corpses seemed to be fleeing in all directions, so they must have encountered something terrible, but at this moment, Wu Liang did not find anything dangerous on this door.

In other words, the reason why these corpses escaped may not be because of the door, but because of the things inside the door.

If it's something inside the door.

That means these corpses may have opened the door in the first place.

After such analysis, an inference immediately jumped into Wu Liang's mind: These corpses may carry "keys" that can open the door!

Thinking like this.

Wu Liang was so busy that he turned back and searched carefully on these corpses again.

But it's disappointing.

After searching all seventeen corpses, Wu Liang found nothing on them that could match the small groove on the door.

And recalling the corpses I encountered on the road.

Wu Liang thought that his inspection was quite detailed, and the things that could match the groove were not too small, so there should be no possibility of missing them.

so.

Isn't the "key" here at all?

Or in other words, was it hidden by someone?

Wu Liang thought of the "water ghost". Although he was not sure what it was, it was considered one of the living creatures in the cave, and it might not be impossible to hide the "key".

besides.

Wu Liang is also not sure whether these corpses that remain here forever have any accomplices who have escaped.

After all, if the half-remaining body died at the exit of the passage, it is possible that someone escaped alive and hid the "key" forever.

"Water Ghost".

Wu Liang definitely didn't want to encounter it again, and he had no way to ask for the "key" from it.

And even if someone escapes.

Now, hundreds of years later, it has long been buried in the ground. Regardless of whether the "key" has been passed down to future generations, Wu Liang's attempt to find it is like looking for a needle in a haystack, so let's not mention it.

Think about it like this.

Wu Liang had completely given up on the idea of ​​looking for the "key". With a slight thought, he decisively took out two items that were also wrapped in layers of linen from the tool bag he carried with him.

The linen cloth was completely soaked.

But it won't affect the contents inside.

As the layers of linen were lifted, two things appeared in front of Wu Liang.

One is the "summoning bell" found in Qiumu Cemetery not long ago.

The other one is a small wooden box with several layers of silk cloth inside, and contained in the small wooden box is the indestructible "Diamond Diamond".

Back then, the "Diamond Diamond" was able to break through the copper wall in Qiumu Cemetery, so it should be easy to deal with this bronze gate.

Thanks to Mr. Qiu Mu for sponsoring the “Diamond Diamond”.

This is the real good thing. With it, almost nothing can prevent him from entering the tomb.

"Ring ring!"

Wu Liang first rang the bell twice, and the "Diamond Diamond" that was still sleeping in the wooden box immediately jumped to life, jumped out of the wooden box and climbed onto his shoulder.

"Ring ring ring ring!"

Wu Liang shook it four more times, pointed at the bronze door in front of him and shouted softly: "Bite!"

"Squeak!"

"Diamond Diamond" responded twice, then immediately jumped from Wu Liang's hand and headed straight for the bronze door.

"Swiss, swipe, swipe, swipe, swipe, swipe"

The industrious little miner got into working mode in an instant. Along with the sparks that kept popping up, the metal shavings were quickly scattered all over the floor. It was indeed a rare thing in the world.
