In fact, the so-called underground river is just a relative term.

If we use higher cliffs as a reference, this is indeed an underground river.

But if we use the river water and the river beach outside as a reference, this river must be regarded as an above-ground river, and it is definitely much higher than the water level of the river outside.

Wu Liang estimated that there would be a water level difference of at least about 100 meters.

Because the channel he was in was about a hundred meters vertically away from the river and river beach outside, and the water level of this underground river was only a few meters lower than this channel.

It's just unclear where the water in this underground river flows.

At least in Wu Liang's eyes now, the water surface of this underground river is very calm. There is no obvious sign of flow to the naked eye. It may just be a pool of stagnant water hidden in the rocks.

besides.

Wu Liang also saw a trail on the bank of the underground river that had obviously been visited by human activities.

This trail is very rough. It looks like it was just a simple excavation in some difficult-to-pass places. The excavated gravel has not been processed and is just piled aside very casually.

On the rock wall next to this path, small holes were cut out at regular intervals.

There was a wooden stick inserted in the small hole, and there were very obvious burn marks on the top of the stick.

This should have been a torch used for lighting.

After the combustion aid soaked in kerosene on the top of the torch burned out, it was difficult for the torch placed upright to continue burning downwards, so a piece of wood like this was left.

Wu Liang carefully observed the environment within the visual range.

After confirming that there was no obvious danger, he finally got out of the passage.

Connected to the passage is a stone step that slopes downward. This stone step is only a few meters long. The craftsmanship is also very rough, and it can only be walked.

The excavated gravel was also piled nearby very casually.

As Wu Liang walked down, he was also observing the chisel marks on the stone steps. These marks seemed to be left by the chisel he just found next to the mummy with only the upper body in the passage.

Therefore, the rough path under your feet is most likely the work of that mummy.

However, such a workload is not trivial. If it is done by just one person, it does not necessarily last long. Therefore, Wu Liang feels that 80% of the mummies must have accomplices, but it is hard to say where these accomplices are.

Already.

So down the stairs.

Wu Liang soon came to a small hole with half a wooden stick inserted.

As he expected, the chiseling marks left on the small hole were also consistent with the chisel, which was also done by the mummy and Wu Liang's accomplices of the mummy.

By now.

Wu Liang has become more and more suspicious that the passage leading into the cave is a tomb passage, and the mummy is also a companion.

Because a serious craftsman does his work so roughly and doesn't even process the carved gravel, there is definitely no way he can pay the employer, let alone get paid.

Unless, this is an unfinished project that the employer never came to inspect and accept.

With this thought in mind, Wu Liang continued walking along the riverside path inside.

After walking about ten meters in this way and climbing up a winding staircase, Wu Liang discovered another very incomplete human corpse.

This human corpse can no longer be called a mummy.

Because the environment here is not dry at all, although this corpse also has only bones left, these bones are not dry at all. On the contrary, there is a layer of moss on the surface, which looks like a body painted with a layer of green paint.

of human bone specimens.

Wu Liang did not touch it lightly, but just got closer to check it.

The death condition of this corpse was also very tragic. His entire right shoulder and arm were missing, and even most of the right side of his chest was missing.

In addition, it can be clearly seen that the cross-section composed of bones at the fracture presents a semicircle.

It felt like being bitten by a huge mouth...

Next to the corpse, Wu Liang found no miscellaneous things, only a chisel.

This chisel is almost identical to the one he got before, except that the rust on it is a little more serious, but it's just a little bit, and it can still be used normally.

"It seems that this is the accomplice..."

Wu Liangzhong speculated this, stood up and continued to explore forward.

But this time, he was a little more careful.

Because the dead state of this corpse made him more and more suspicious that there was something extraordinary inside. Not only was this thing incredibly powerful, it should also be very large...

Wu Lianglian thought of the "River God" he had seen on the cliff before.

The "River God" is very large, with a face that can reveal a sly smile as big as a sewer manhole cover, and a mouth that can be grinned directly to the back of the head. It should be easy to bite off half of an adult's body in one bite.

But the question is, can the "River God" enter this cave?

Wu Liang expressed doubts about this.

Because speaking of this underground river, according to common sense, it should not be the same as the Canglang River outside. Otherwise, the water levels of the two rivers would be consistent, and there would be no such a big height difference.

But if it weren't for the "River God", this wouldn't be good news for Wu Liang either.

This shows that there is another more dangerous thing in this cave. From a certain level, this can also be regarded as an internal worry.

More importantly, Wu Liang knew nothing about this more dangerous thing in the cave.

This will undoubtedly further increase the possibility of him accidentally falling into danger...

"Gulu..."

Wu Liang is a man of flesh and blood, and as a human being, he will feel fear, especially when facing something unknown and dangerous.

But now that the matter has come to this, he can't give up under any circumstances.

Public transport tomb!

This is the tomb of the legendary master craftsman Lu Ban. Even if we look at the history of the Celestial Dynasty for thousands of years, this master is still a famous figure.

What's more important is that later archaeological circles never found this tomb.

All knowledge about him comes only from fragments of official history, and the rest are baseless but miraculous folklore.

Wu Liang was eager to find the Gongshu Tomb and learn more about Lu Ban.

This is the main reason why he chose to major in archeology in his previous life, and after time travel, he was willing to be used by Boss Cao, joining the Hu army and constantly putting himself in danger.

He wants to understand the most authentic history and explore the truth of history.

Instead of watching the historical truth buried in the torrent of history when he clearly has the opportunity to find out, this will make him regret for the rest of his life.

So I calmed down a little bit.

Wu Liang suppressed the uneasiness in his heart, stepped over the corpse and continued walking deeper.

…

As he continued to go deeper, Wu Liang encountered several corpses one after another.

These corpses were also in a state of mutilation, some were missing arms, some were missing legs, some were missing half of their bodies, and some were even missing their heads.

They should all be from the same group of people, and they all carry more or less tools with them, the most common of which are chisels of the same specifications.

This proves that Wu Liang’s previous judgment was correct.

They formed a team and came to this place, built the hanging coffin on the cliff, then dug out the passage hidden behind the hanging coffin, entered the cave together, and then died in the cave.

Wu Liang is still unable to determine their identities.

I don’t know if all the people in this group died here. After all, some people died in the entrance passage, so they might have escaped before that.

But there is one thing Wu Liang is becoming more and more certain of.

Their goal is probably to hide in the nearby Gongshu Tomb, because their methods and the tools they carry are very similar to those of tomb robbers, especially the compass they found earlier and the cinnabar ink fountain...

Under this.

Wu Liang walked along the riverside path for about tens of meters, and actually came to the end of the underground river.

The underground river was blocked by a slippery rock on slightly higher ground, and it seemed that there was nowhere to go ahead.

But the riverside path was not interrupted.

The path continued to extend forward, and an equally rough stone step climbed up to the slippery rock blocking the underground river. It was unknown where it led.

Wu Liang climbed the stone steps carefully.

Soon we reached the top of this slippery rock, and then... our eyes suddenly opened wide!

The illumination range of the Suihou Bead is much stronger than that of a torch. Even in an absolutely dark environment, it can illuminate a distance of tens of meters if there is no terrain obstruction.

But at this moment.

In Wu Liang's eyes, in addition to the surrounding slippery rock walls, what was in front of him was a huge slope that sloped downward.

The inclination of this slope seems to be about 60 degrees. In addition to the uneven and slippery rock walls, there is only a narrow stone step that can only accommodate one person!

This road is much more difficult than some famous mountains and historic sites in later generations.
