If you look closely, there is a faint smell of sulfur in the air in the cave, and the sultry temperature in the cave makes Jialan wonder if there is still some lava lake nearby.

The aura of their group of outsiders quickly attracted the attention of the giant rat group, and when a pair of green eyes appeared in the fungus, Captain Kenmet waved his hand decisively: "Withdraw to !!"

After a group of people quickly retreated due west to the crack of the secret door, five silver mercenaries formed a battle formation, using the narrow terrain to defend the crack and block the steady stream of rats.

The scale of this "rat nest" is huge, and there are probably not a few giant rats and dark demon rats living in it, and it is obviously not just their 10-person expedition team that can be cleared out.

After a little discussion, Jialan took out the "Communication Mirror" and contacted Casey and Div on the ground, asking them to gather hired workers to enter the dungeon with tools, sort out the other party that had been abandoned for hundreds of years, and rebuild it into a base camp and transit station for ruins and wasteland.

The head of Kenmet also contacted his two deputy commanders through the "Mirror of Communication", summoned the remaining mercenaries to come to support, and at the same time, the two sides also issued martial law and gag orders, and strictly prohibited any news about the ruins from leaking out until the underground ruins were cleared.

While waiting for the support to arrive, Jia Lan took out the strange gem, and under the surprised gaze of Kenmet and others, a three-dimensional phantom was projected into the air by the gem, and if you carefully identify it, you can tell that the picture shown on it is a miniature of the area they passed through after entering the dungeon.

Seeing the surprised eyes of the mercenaries, Jia Lan explained simply: "This is a 'positioning gem', which can record the route we have taken! Both are a type of magic item that can be used for exploration. ”

As she spoke, Jialan stroked the positioning gem, enlarged the area of the rat's nest they had just entered, and turned it into a plane, presenting it in front of everyone like a map.

This "phantom map" floating in the height of half a waist of everyone roughly presents the topography of the rat's nest, which is a small underground cavity, because of the humid environment caused by the underground river, a large number of fungi and mosses have multiplied in the underground cavity, forming a very peculiar ecological environment.

And Jialan the rift passage they just entered. It's just one of the branches of this underground cavern.

"Look here! we're in this location..."

Jialan enlarged the phantom map to the limit, pointing to a corner of the phantom map about the size of a round tabletop, and everyone focused their attention, only to see Jialan waving her finger in a corner of the phantom map. A mark symbolizing the door was marked with an arcane sigil.

"This is the underground fissure and the underground river that we just saw, further along. You notice there's not a lot of broken rock and regular-shaped rocks..."

Jialan's finger moved across the map. Pointing to a corner not far from where they had just been found by the giant rat swarm, "Those rocks are clearly artificially carved, and I suspect there is access to other areas of this ruin." ”

The crowd gathered around the phantom map and looked curiously, the map projected by the positioning gem was translucent, revealing the underground cavity of the rat's nest in the form of a cross-section.

Their current location was marked with a bright spot by Jialan with a secret imprint, and the bright spot was the center of the circle. Places as far as the eye can see are highlighted, and you can clearly see the miniature environment on the virtual map.

And out of sight, but the location that has been. It is shrouded in a hazy shadow, and as for the area that has not been visited, it is simply dark.

The most interesting thing is that next to the white bright spots that symbolize the location of the positioning gems, there are also several small green bright spots, and in the space opposite the fissure, some small red dots emerge from the shadows from time to time, and these small red dots are still disappearing.

There was no need for Jialan to explain, and the mercenaries also understood the meaning of these little green dots and small red dots, the green dots were their teammates, and the red dots were those giant rats.

Captain Kenmet was furious at the two magic props in Jialan's hand, the Communication Mirror and the Positioning Gem, which were very useful in adventures, but he also knew that this thing could not be used by anyone except the magician.

Although he also has a group of resident magicians under his command, this young magician must not be willing to sell this rare magic item, right?

Therefore, although he wanted these two magic props very much, Kenmet still resisted this presumptuous thought, and was embarrassed to ask Jialan if he was willing to transfer it, but after his mercenaries arrived, he immediately began to direct the mercenaries to counterattack the rat's nest.

The Golden Two-Headed Dragon Mercenary Regiment can become the leading large mercenary group in Corland County, in addition to the care of President Clark, the former head of the regiment and the current president of the Mercenary Guild's Corland City Branch, its own strength is also quite strong.

Among the more than 1,600 mercenary members, there are more than 1,000 in the Black Iron Rank, more than 500 in the Bronze Rank, and the relatively rare number of Silver-level mercenaries, the Golden Two-Headed Dragon Mercenary Group has as many as sixty or seventy!

Even the high-end combat power of the mercenary world like the "Golden Mercenary", including the head of Kenmet himself, has as many as five Golden Two-Headed Dragon mercenary groups, so although in terms of the total number of members, perhaps the Golden Two-Headed Dragon is not as many as the other large mercenary groups in Colan City, but in terms of combat power alone, it can be ranked first.

Recently, due to the cooperation between President Clark and Jialan, the Golden Two-Headed Dragon has terminated other activities and withdrawn all personnel, just as it was claimed to the outside world, using Fort Doom as the headquarters of the mercenary group.

Therefore, through the mirror of communication, the elite members of the group were quickly summoned, not only the five gold mercenaries and all the silver-level mercenaries were present, but even the magician group supported by the golden two-headed dragon mercenary group was also activated.

A fire high-level magician, five intermediate-level magicians, and more than a dozen junior magicians were collectively present, the scene was quite spectacular, and it was also thanks to the strong family background of the golden two-headed dragon, otherwise it really couldn't afford to raise such a large number of magicians.

In the words of Captain Kenmet himself, even if they were carrying out some large-scale missions, their golden two-headed dragon had not made such a large investment in personnel.

The combat power of almost twenty magicians plus five golden warriors and dozens of silver warriors is enough to start a small-scale city-state war, so it can be seen that the previous battle with the four golden skeletons, as well as the strange teleportation in the Jiuyao Hall, did frighten Captain Kenmet.

The mercenaries who rushed to support dragged the giant rat corpse, which was almost filled with the rock cracks, out of the gravel pit, and transported it to the outside of the dungeon and handed it over to the full-time personnel of the team to deal with.

After all, the giant rat is also a kind of earth-based magical beast, although it is only black iron level, but no matter how small the rat is, it is also meat, and the magic crystals in their bodies, as well as fur, bones, and minions, are all quite good materials, and if they add up, they can be regarded as an income.

Because hunting Warcraft to harvest materials is also one of the regular tasks of the mercenary group, the mercenaries are extremely skilled and cooperate with each other, although there are many personnel, there is no confusion at all.

A group of mercenaries dug up a large amount of earth from the mud-filled secret door due east, mixed with the collapsed gravel in the ring hall, and filled the hole in the ring hall that was dug out by the giant rat, as well as the gravel pit due west to the rock crack in the secret door.

And began to use local materials and gravel to build a staircase connected to the upper dungeon warehouse, and when they completed the basic construction, an earth-based intermediate magician waved his staff and released the intermediate magic "Rock Shaping" and "Soil Reinforcement".

These two intermediate magics not only make the dirt ladder and the filled ground as solid as rock, but also widen the originally uneven rock cracks, trimming and smoothing, which is very magical.

Seeing that the intermediate magician, who was almost equivalent to the "second-order mage" of his time, easily changed the shape of the rock, Jialan couldn't help but be secretly surprised, because among the arcane secret techniques of the Dao, he also had high-level spells of similar nature, but they were definitely not the ones that the "second-order mage" could release.

Of course, the kind of spells that Jialan knew about Lu Dao, which were jokingly called "city building" and "city breaking", "turning mud into stone" and "fossil into mud", were not comparable to the earth-based magic "rock shaping" and "soil reinforcement" of this era, and it was not an order of magnitude at all.

Although the number of giant rats was huge, they could not withstand the fierce fire of the mercenaries, and they were soon cleared out of the cave at the passage, and a large number of black iron-level mercenaries and under the leadership of their respective bronze-level squad leaders, rushed into the rat's nest and launched a large-scale clean-up of the rat's nest.

There are dozens of silver-level mercenaries and junior magicians in charge, and a fat and huge dark demon rat is also difficult to stop, once it appears, it will soon be surrounded and killed by the mercenaries, and the corpse will become the trophies of the mercenaries.

Compared with the low-level demonic beast such as the giant rat, the corpse of the silver-level demonic beast of the dark demon rat is obviously more valuable, not only the fur and minions are good materials for making armor and weapons, but even the blood and internal organs are also quite rare magical materials.

Since giant rats and dark demon rats usually appear in dangerous underground ruins, the danger of hunting them is quite high, and suddenly in such a place so close to the city and not deep from the ground, such a large number of giant rats and dark demon rats were found, which was also a surprise for the Golden Two-Headed Dragon Mercenary Group.
