The Nebula Mountains, 50 miles from Turin, have little vegetation in the mountains, and it is said that in ancient times, this was a volcanic area, and after hundreds of millions of years, the volcano has completely fallen silent, but it has left behind many rich minerals and unique products, which have become the main source of great wealth for the Kingdom of Orsay.

Since the seizure of this mountain range from the Grey Dwarves more than 10,000 years ago, four famous mining cities have formed around it, which belong to a corner of the mountain range, blocked by mines and connected by teleportation circles.

Around the four cities, is the merchants, absenteeism, absenteeism family spontaneous gathering of villages and towns, since the implementation of the aristocratic feudal system, all the villages and towns have been divided by large and small nobles, but the four main cities still belong to the royal family of Orsay, this is the bottom limit of the royal family of the past dynasties, even if there are major temples and nobles coveted have never changed.

Therefore, the reward order jointly issued by the city lords was actually from the hands of the royal family, and as one of the royal mercenary groups, the fox hunting mercenary group, this mission was strongly supported and welcomed by the four city lords.

Early in the morning, the mercenary group entered the city, and after a short repair and the last supply, the officials of the city hall sent the drawings of the mining area, knowing the location of the destination and the topography and information along the way, and the mercenary group left the city again and headed for the entrance of the 109th mine, the destination.

There was no danger along the way, the undead creatures and the monsters in the dark underground shown on the intelligence were also missing, and there was silence along the way, not even a goblin as ubiquitous as a mouse could not be found, the mercenary group did not relax its vigilance, but became more nervous and strict, the closer to the destination, the more you could feel the convergence and richness of the dark power, the sky became dark and oppressive, the air had a smell of rust, and not much vegetation was listless, not a single living creature could be seen, and a birdsong could not be heard.

The mercenary regiment spread out in battle formation, with the front scout lines spread out over a wide front, and the swordsmen, shield warriors, and heavy armor warriors were divided into four parts, located in the front and rear of the team, and on the left and right sides of the group, enveloping all units in their defenses. Ranged attack units are at the end, Marksman, Jungler, Hunter, etc. At the heart of the group, the mage's carriage was heavily wrapped, and beside the carriage, the mercenary captain accompanied his command unit.

The mine was far away, the terrain became rugged, and after about five minutes of vigilant advance, he began to enter the dilapidated outbuildings under the mine, through this dead and silent complex of dilapidated buildings corroded by dark energy, and along the extension of the railroad tracks under his feet, in a huge gap, the entrance to the mine was found.

The entrance is not small, it can accommodate two rows of parallel rails, a minecart is dumped aside, and the ore that has been preliminarily screened is sprinkled on the ground, in Wu Chen's eyes, the green, yellow, and red texture of the ore occupy the vast majority, copper and iron?

The entrance is quite deep, because this is a magical world, so the mine does not need to have a complex support structure like the earth, it is reinforced by magic, and only in deep areas that are disturbed by the buried magic will there be wooden or iron supports.

A series of orders were delivered, and the mercenary group began to build a camp close to the entrance, the ore and iron tools that could be found everywhere were used, and a large part of the corroded outbuildings were demolished for the construction of the wall, and the trench around the entire camp progressed very unsmoothly, and every inch of the soil here was unusually hard because it contained metal, Lias stepped forward and chanted a spell, and Wu Chen followed.

After three "fossils to mud" spells, the progress of the trench was greatly accelerated, and by midday the camp was beginning to take shape, at least the outer layer of defense was fully formed.

Lunch was dealt with under intense and orderly deliberation and arrangement, and the result of the deliberations was nine professionals plus thirty carefully selected elites of all kinds (mercenaries about to break through. As the main force of exploration and sweeping, the members of other mercenary groups are in the role of deputy head (not a formal professional, in charge of logistics, support, and auxiliary command. Hold the camp.

Looking at the environment of the mine, it is impossible for all 200 people to go down in a swarm, that is not an expedition but a suicide, and the role of most of the elite members is to ensure the back road and guard against the enemy's possible numerical superiority.

The nine official professionals and thirty quasi-professionals are further divided into two parts, one team is biased towards exploring and checking for traps and deciding the route forward, and the other team is focused on protecting the back road and attacking and sweeping, Wu Chen is assigned to the rear team, and Lias is assigned to the front team, both of them are tightly protected in the center as the output core of the team, the commander of the front team is the regimental commander Yakoto, and the commander of the rear team is the second-level swordsman Edward, a two-handed sword warrior as strong as a bear.

As the core of the team, the main strike unit of his teammates based on high hopes, Wu Chen was very apprehensive, the "Rainbow Spray" had already been remembered, and the completion of the memory was still in the chaotic space, with the help of such absolute purity and sanity. As for the principle of the structural model, there is only a vague conjecture that has not been tested.

In the final preparation time, Wu Chen sat upright in his newly built tent, his staff rested on his knees, exuding an ice-blue halo, the spell book was opened, and the rainbow spray spell was chanted, as a unique spiritual imprint deeply imprinted in his consciousness.

He estimated how many rainbow sprays he could cast, there was no limit to spell bits, the mental power was more than enough, and the only criterion for measuring was how many times the magic could fill the structural model, ten times, or eight, thank God, he didn't need to be like a mage, he had to memorize the structural model again after casting it once, and I have to say that this is another huge advantage.

The incantation was muttered, a syllable was wrong, and the magic power that had just been agitated violently spread in his body, Wu Chen's face turned pale, and his body trembled for a while before he stabilized himself, and after he completely calmed down, he didn't dare to have any luck, and immediately entered the chaotic space, practicing over and over again with the help of the purity and sharpness there.

Rainbow Spray, the system of change, that is, the primary application of the death effect, is the primary level of dissociation, cleavage, the competition is the caster's spell ability and the relevant resistance of the recipient, once cast, there are only two effects, either the ineffective unharmed, or the body collapsed and died, in addition to ignoring all factors, even dragons are no exception.

Of course, no one uses a rainbow spray to kill a dragon, that's looking for death.
