Chapter 1208: Earth diving

The tight mud layer in front, as well as large chunks of rock, touched the yellow magical brilliance that emerged from Joan's body, crushed apart like snow, opening him a way forward.
However, when Joanne took a step forward, the road behind him was immediately filled with sand, but the texture became extremely loose.
Joan compared with the route on the map, gradually deeper into the ground. While rushing to the road, he suddenly had a funny thought, feeling like a big earthworm, working hard in the depths of the soil.
After walking forward for about five minutes, Joan found the entrance to the ground navel where the flail snails dived, and the tunnel in front was still filled with mud.
Joan walked far away in the tunnel blocked by sand and stone. It was not until the magic of "Second Stone Walk" was about to be exhausted that the front was suddenly bright and empty.
Joan relieved himself secretly, shaking off the sand and comparing the navigation compass to the route he had traveled.
After some simple calculations, Joanne found that the tunnel open space he was standing at this moment, and the ground above where Klein and others were located, had a vertical drop of nearly 700 feet, which had exceeded Klein's maximum transmission distance.
The dwarf miners need to dig down a 100-foot deep tunnel to reduce the vertical drop to within 600 feet, providing Klein with a safe path for "any gate".
Joan extracted two "Sid Mana", performed 2 rings of "Windstorm", and transmitted the data he surveyed to Klein and others.
Five minutes later, after receiving a reply, Klein had summoned all the dwarf miners and excavated along the route that Joan had just walked.
Although the stratum once "plowed" by Joan became very loose and easier to dig, the tunnel with a depth of one hundred feet has a large amount of engineering. Even if the dwarf miners dig overnight, it will not be completed in one day.
Qiao An wanted to bless the "secondary stone walking technique" again, turned back the same way, inadvertently glanced deep into the tunnel, and found a trace of reflective light, unable to move his heart.
Raising his hand and snapping his fingers, the blood mosquitoes spied out of the pocket of his coat and flew towards the reflective trace.
Joan switched his perspective to the blood mosquitoes and observed the reflective zone. Sure enough, it was a narrow glass mark attached to the ground, extending towards the depths of the tunnel, and the luminous path disappeared at the end of darkness.
Joan was intrigued by the wonders in front of him. Anyway, nothing happened, and he ordered the blood mosquito to trace the path along the glass track, followed by himself, trying to track down the flail snail.
Going forward about half a mile, the winding tunnel still has no end, but Joan keenly perceives that the rock wall on the left seeps light blue, and granular crystals are faintly visible.
This special rock layer is exactly the characteristic of the magic crystal vein!
This discovery excited Joan, quickly opened the navigation compass, recorded the currently surveyed veins, and marked the coordinates.
A further way forward, the blue ore disappeared, and the rock layer in sight turned into ordinary sandstone.
Joan was not disappointed by this. Before actually entering the core zone of a rich ore, the veins observed on the periphery were always intermittent, sometimes from time to time. The closer to the core area, the more frequent the occurrence of veins.
If you want to obtain the mining rights of a mineral deposit, it is useless to only explore the surrounding mineral veins. According to the principles recognized by the exploration industry, only the team that first reaches the core area of ​​the mineral deposits and maps out the complete mineral vein distribution map will have the right to discover.
Joanne now takes a step forward, while taking risks at the same time, also adding a competitive advantage to his prospecting team.
A further way forward, an empty cave appeared at the end of the tunnel.
Through the eyes of the blood mosquito, Joan saw a huge shadow creeping in the cave, and there were vaguely creaking noises, as if someone was chewing hard candy.
Joan felt that something was about to happen. He quickly blessed himself with "Mage Armor" and "Shield Technique", thought for a while, and added a "stealth technique" to quietly enter the cave.
With the help of the "dark vision" attached to the prosthetic eye, Joan found that the dark blue crystals around the stone walls that were raised and mottled, were the magic crystal ore that once disappeared from his eyes.
Natural magic crystal ore, the impurity content is too high, in fact not very valuable.
Even if it is a high-grade magic crystal ore, an average of 100 tons of natural ore can only smelt 1 pound of industrial magic crystal with a purity of 10%. One can imagine how low the magic crystal content of natural ore is.
The market price of a ton of high-grade magic crystal ore is around 50 gold duga.
Two years ago, when Joan was so poor that he had caught leeches to make money, he was happy to mine ore for money.
However, times have changed, and now he has been reluctant to sell his coolies to earn such a small amount of money, but just picked up two pieces of ore and put it in a storage bag as a specimen.
Going forward for some distance, when approaching the middle of the cave, Joan finally saw the shadow. It turned out to be a huge snail, burying his head to eat the demon crystal ore, and there was a glowing crystal trail behind his butt. , Is not that he traced the flail snail for a long time!
The crunch that Joan heard just now was the movement of this guy chewing ore.
Seeing that the flail snail has such a good mouth and so sweet food, Joan couldn't help rubbing his belly and was a little hungry.
It was at this moment that a grunting bowel sounded in the stomach of the greedy worm.
The big snail, who was eating the ore, was suddenly alert, shaking his tentacles and turning his head to look at Joan.
The two sides are facing each other, and Joan can see the appearance of the flail snail.
This huge snail carried a hard shell like a small house. At first glance it was colorless and transparent, and vaguely visible creeping flesh and blood in the shell, but Joan looked closely and found that the snail shell had a dimly colored luster, like glass Reflect in the sun.
The flail snail has four slender and flexible antennae protruding from its head, and at the end are calcified indules like mace, which are strong and full of oppression.
These tentacles connected to the hammerhead are the reason why the big snail is called "flail".
Qiao An clutched her stomach tightly, fearing that there would be no more movements, holding her breath, standing still against the rock wall.
The flail snail has both "dark vision" and "tremor perception". If Joan moves his body, even if it is protected by "stealth", he will still be aware of it.
But Joan stood there immobile, and the "breathing in the water" blessed him so that he didn't need to exchange air with the outside environment, so he would not cause airflow disturbance due to breathing, triggering "tremor perception".
