Mage Joan

For security reasons, Joan prevented Guru from approaching the cave and ordered it to withdraw to the safe zone as soon as possible.

However, Joan did not intend to give up the investigation inside the cave. It's just that he has to change to a safer and safer way of investigation.

Joan takes out the navigation compass, recites the start spell, the compass raises the magical glory, and automatically generates the surrounding map.

The valley where the War Lizard camp is located is not far from where Joan is located. With the aid of the three-dimensional map presented by the navigation compass, he can clearly see the caves excavated above the rock wall.

Most of these caves are relatively shallow, just the war lizard's residence, the space does not need to be too large.

However, among all these caves, only one is particularly deep, and the internal space is particularly large, that is, the cave that is protected by spell enchantment and guards, and often roars.

Joan magnified the picture on the navigation compass corresponding to this mysterious cave.

From the profile view, you can see that a tortuous tunnel extends inside the cave entrance, slanting deep into the mountain, looks like a pit, but I don't know what minerals are being excavated.

During the adventure, Joan and his companions will always use "perspective hand mirror" or "exploration ring" to see if there are mineral veins under their feet. It is a pity that no valuable mineral deposits have been found so far.

At this moment, Joan couldn't help but see the cave in the valley suspected of pits, guessing that the cave is likely to be buried with rare minerals.

The observation radius of the "perspective hand mirror" is only 100 feet, and Joan cannot explore the pit far away from the valley from where he is at the moment. Fortunately, he has other methods for remote detection.

"Apacenya!"

Singing softly to start the mantra, Joan activates the 3 rings of "Eagle Eyes" attached to the prosthetic eye. Then, according to the map of the pit shown by the navigation compass, set the magic observation point in the middle of the tunnel.

Joan closed his eyes and switched his perspective to the observation point created by "Eagle Eyes".

After a few seconds, when he opened his eyes again, he found himself in a dark and deep mine pit.

Of course, it is not the actual flesh that enters the pit, but only a ray of consciousness attached to the observation point. Even if this observation point is destroyed, the loss of this consciousness will not cause any damage to Joan himself.

Through this new perspective, Qiao An slowly looked around and found that the tunnel was about five feet wide and eight feet high, and the cross-section was quite regular.

War lizards are unlikely to have any advanced magic excavation machines. It is difficult to imagine that such a spacious and regular tunnel can be cut with humans and simple tools.

Joan first put this doubtful aside and carefully observed the excavation marks on the tunnel wall.

The walls of the cave are roughly flat, but on closer inspection there are traces similar to sharpening.

Judging from these excavation marks, the rock formation was dug by a device similar to a flat-headed shovel.

Considering the hardness of the rock, this type of excavation device must be extremely sharp!

Joan continued to observe and soon found a second doubt.

A thick layer of frost has condensed on the rock surface of the four walls of the tunnel. It can be seen that the humidity inside the tunnel is very high, and the temperature is lower than the freezing point.

This is really an incredible sign!

Joan’s location at the moment is a linear distance from the underground pit, only about one mile, and the height difference will not exceed three hundred yards.

In such a narrow range, even if the temperature difference between the surface and the underground is considered, the gap will not be very large.

The temperature here is quite warm here, why is there thick frost in the pit not far away?

His first thought was the "ice cellar effect".

The south of Yalfheim is very hot in summer.

The manor owners in the south will always collect a lot of ice in the winter and store it in the cellar. In the summer, the ice will be taken out to cool down the heat.

Indeed, because the thick soil layer is not conducive to heat conduction, ice cubes can be stored in a well-sealed cellar for a long time, and it will not melt during the summer season.

The pits in the valley are covered with frost. Is it because the pits store a lot of ice?

Even if this is the case, the open door of the pit does not meet the sealing standards of the ice cellar, and the tunnel has not grown to the point where it can significantly delay the heat exchange.

Heat exchange takes place inside and outside the cave door, and the temperature inside the cave should keep rising, but Joan found no signs of melting the frost.

This indicates that the temperature inside the cave is extremely low, and it is likely that there is a low temperature source that counteracts the heat conducted into the cave entrance.

Natural heat sources are everywhere in nature, such as volcanoes and hot springs, but natural low temperature sources are too rare!

Joan had to suspect that the frost that had formed in the pit might be a low temperature effect caused by magic or supernatural forces.

With the thought of tracing the roots, Joan once again inspired "Eagle Eyes" to create a second magical observation point in the second half of the tunnel and switch his perspective.

Looking through the second observation point, Joan found that the temperature here was much lower than the first observation point.

Here, what is condensed on the walls of the tunnel is not white hoarfrost, but thick ice.

In fact, Joanne could no longer see the rocks, and looked around, covered with smooth ice.

There was frequent rumble and roar from the depth of the opposite cave, as if someone was digging a tunnel deeper.

Digging into the roaring interval, Joan also heard the conversation, but unfortunately the voice was very vague, and I couldn't hear anything more.

At this moment, footsteps came from the end of the tunnel.

Immediately afterwards, several shaking figures appeared.

Joan breathed his breath and peered through the observation points set in the shadows to spy on people walking in the tunnel.

It turned out to be four war lizard miners.

The whole body was surrounded by a thick coat of animal skin. The two were in front, dragging an open wooden box that was nearly full of the tunnel with a leather rope, the wooden box was filled with crushed ice, and the other two pushed the wooden behind. box.

The four people even pulled and pushed together to move the big wooden box.

The bottom of the wooden box rubbed against the smooth ice surface and made a creaking noise, slowly sliding towards the side of the hole.

These war lizard miners talked in a low voice while working hard.

The language they use is very weird. At first it sounds like Dragon's language. It also contains a lot of underground dialects.

But combined with their attitude, it is not difficult to guess that it is probably complaining about the hard work and the harsh environment, and it is almost necessary to freeze people alive!

The team of four miners passed under Joan's observation point, no one looked up.

Shortly thereafter, another group of war lizards pushed a wooden box filled with crushed ice past this place, dumped the crushed ice outside the cave, and then dragged the empty box back to the depths of the tunnel.

By observing these busy war lizards, and then looking back at the map drawn by the navigation compass, Joan felt more and more amazing as he looked at it!
