Chapter 734: Old Blind Man

The stratigraphic structure of this valley is very special.

Metaphorically speaking, it is like an egg, only a thin layer of sand and rocks on the outer shell, and a thick layer of solid ice on the inside.

The troglodyte miners dug down from the surface, and after digging out about 10 yards, they cut through the thin layer of rock and soil. They continued to dig deeper, and what they dug out was ice sand!

How thick is the subsurface ice?

Judging from the hydrographic mapping generated by the navigation compass, it may be no less than two or three hundred yards!

How did such a large ice block, like a glacier buried deep in the ground, come about?

Joan can only think of one possibility for the time being.

Under the valley, there was originally an underground lake. Later, due to changes in the earth's crust or some supernatural factors, the temperature of the ground dropped sharply, and the entire underground lake was frozen into a huge lump of ice.

The lake water condenses into ice, which decreases in density and increases in volume.

The rapidly expanding body of water (ice) squeezed the rock and soil layer, forcing the surface to uplift, thus forming the hill where Joan and his companions are at this moment.

The "orogeny" that occurred in the underground world is so similar to the similar natural phenomenon in the surface world!

As for the deep valley below the hill, it is actually a crack formed by the expansion of ice blocks to break through the rock and soil layer.

After figuring out the cause of the abnormal local geographical environment, Joan still has two questions.

First of all, he would like to know why the groundwater freezes into ice, and where is the source of the low temperature?

Secondly, he didn't understand why the troglodytes had to work so hard to dig tunnels and dig through the ice.

Could it be that there is some kind of treasure sealed inside this huge ice body, luring the Lizardmen to spare no effort to dig deep?

The more Joan thought about it, the more curious he became, and he decided to see the excavation site at the end of the tunnel with his own eyes, and maybe he could find the answers to the above two questions from it.

Thinking of this, Joan inspired the last "Hawkeye Spell" of the day, clinging to the end of the tunnel, creating a third magical observation point.

Closing his eyes and holding his breath for a few seconds, Joan slowly opened his eyes, and his perspective jumped from the second observation point to the third observation point just created.

The environment here is similar to the location of the second observation point, surrounded by thick ice.

The tunnel here has just been excavated, and the ground is still covered with thick ice slag.

A group of troglodyte miners were working on the site with crude tools, shoveling up the crushed ice accumulated on the ground, packing them into large wooden boxes, and dragging out once the box was full, so as to ensure the smooth flow of the tunnel.

In this busy workplace, Joan noticed two unusual figures.

One of them also appeared to be a troglodyte, and was the only one there who didn't have to work.

This war lizard man was hunched over, coughing twice from time to time, the scales on his body were dull, and some of them had even peeled off, giving an impression of aging.

This old troglodyte old man held a cane carved from obsidian, and a honey-colored amber ball was inlaid on the head of the cane.

Joan noticed that there seemed to be a shadow in the amber ball. After careful observation, he confirmed that there was a prehistoric Orthoptera insect sealed in the amber ball with the head of the stick. It looked a bit like a locust...to be precise, it should be the ancestor of the locust. ?

A natural amber ball as big as a fist is worth no less than two thousand gold durga, and it's not just an ornament.

Joan vaguely felt that the obsidian staff in the old lizard man's hand was emitting magical fluctuations.

Unsurprisingly, it should be a magic wand!

The clothes of the old troglodytes are also very unique.

Wearing a robe made of animal skin, in terms of the craftsmanship of the Lizardmen, it can be called a decent style. Only the elders in power who are highly respected in the ethnic group are worthy of this carefully sewn robe.

What's even more rare is that the robe is even decorated with colored thread embroidery!

After some careful observation, Joan found that there were many lifelike red-headed centipedes embroidered on the robe of the old lizard man, each of which was as big as a palm. Following the old man's every move, the big centipedes embroidered on the leather robe seemed to be crawling and wriggling.

Do normal people embroider centipedes on their coats?

Joan was secretly surprised.

Not to mention the old man's wonderful aesthetic taste, those lively centipede embroidery are not just decorations!

The distribution probability of the magic net around the old lizard man is obviously abnormal, which can be seen to be distorted by the centipede robe.

Joan was sure that some kind of spell was attached to the robe. It's a pity that the distance is too far, and he can't identify what spell is enchanted.

An elderly troglodyte, wand in hand and robes, patrols the underground mines with pride. Among the busy lizard men around, none of them dared to look up at him.

There are various indications that this old guy has a very respected status in the Lizardmen tribe, and he is likely to be a powerful figure such as the Great Shaman or the Great Elder in the tribe.

The "magic alarm" in the troglodyte nursery, as well as the barrier at the entrance of the mine, must have been set up by this person.

From Joan's point of view, only the profile of the old lizard man can be seen.

When he was guessing the other party's identity, the old lizard man seemed to have noticed something, turned around suddenly, and looked up at the observation point set by Joan.

Joan was taken aback when he saw this, and almost immediately fled from the observation point.

However, at this moment, he noticed that there was no light in the eye sockets of the old troglodyte, and the two eyeballs were gray and cloudy, as if covered with a thick white film.

It turned out to be an old blind man!

Joan's tense heartstrings eased a little, and the perspective remained at the current observation point, let's see what the old blind man will do next.

The old troglodyte apparently suffered from a serious eye disease, almost completely losing sight.

He looked up at the shadow where the observation point was, frowned slightly, and a trace of doubt appeared on his face.

It seemed that he had found some suspicious signs, but he was not sure.

After a brief wait and see, the old blind man turned his head around, apparently dispelling his suspicions.

Seeing this scene, Qiao An breathed a sigh of relief, feeling that she was safe.

Just then, the old blind man walked towards the end of the tunnel.

In the deepest part of the work site, there is a huge black shadow crouching, digging the ice.

Only from the back of the other party, Joan couldn't tell what kind of monster he was.

But one thing is for sure - this guy is an efficient digging machine!

It lay down in the depths of the mine and buried itself in digging, constantly throwing out large chunks of crushed ice.

More than a dozen troglodyte miners followed it to clean up the crushed ice, and carried the crushed ice out one by one, so busy that their feet didn't touch the ground.

That's it, they couldn't keep up with the monster's digging speed, and the broken ice behind him accumulated more and more.

The monster had to stop digging, waiting for the troglodytes to clean up the piled ice.

The old blind man walked unhurriedly behind the giant ice digging monster, waved his wand and tapped it on the back twice.

The monster turned around slowly, lowered its head and approached the old blind man, as if listening to his orders.

The old blind man whispered a few words in the monster's ear, then pointed his obsidian wand at the observation point of the "Eagle Eye" and led it over.
