Deep in the Rat Cage Hall, the flames raged like a mad dragon for a whole day, releasing suffocating heat waves and indescribable stench, forcing the brave mercenaries to temporarily retreat to the Castle of Doom to take turns to breathe and rest.

  When the mercenaries mustered up their courage and pushed open the heavy secret door again, the wind mage displayed his superb skills, using the breeze as a blade to cut through the smoke and hot shackles.

  Even those experienced mercenaries, after seeing the tragic scene in the Rat Cage Hall, couldn't help but lean on the wall and vomit.

  The scene was no longer "corpses everywhere" but like a purgatory on earth.

  In every corner of the hall, there were piles of charred rat corpses, like small hills.

  And in the center of the hall, the huge metal cage that once imprisoned countless dark demon rats had long disappeared, replaced by a huge mountain of charred corpses, almost touching the dome of the hall that was more than 20 meters high.

  The bones fell like dead leaves, and turned into dust with a light touch.

  The number of these rat corpses was far more than two thousand, and it was conservatively estimated that there were tens of thousands of them.

  Especially the mountain of corpses, which witnessed the desperate struggle of the rat queen in the flames. It summoned its offspring to protect itself, but it didn't know that this was the death warrant that pushed them into the abyss.

  The earth mages used their skills to block the forks and dead ends in the Bailong Labyrinth with earth walls, leaving only one way to survive to prevent accidental entry.

  Afterwards, the mercenaries led the hired workers to transport the charred rat corpses out of the rat cage hall one by one.

  Kenmet looked at the busy figures of the hired workers, and his heart was full of reluctance.

  Tens of thousands of silver-level monster corpses! If they could be preserved, even the decomposed materials would be enough to exchange for millions of wealth.

  However, all this was destroyed by Jia Lan's fire.

  The resentful look of Captain Kenmet made Jia Lan feel guilty, but fortunately, it was not a complete failure. The tens of thousands of silver-level earth magic crystals were enough to comfort the injured heart of Captain Kenmet.

  At that moment of life and death, it was a blessing to be able to save his life. Even if there were some twists and turns in the process, the final result was still perfect. Tens of thousands of dark magic rats were wiped out without bloodshed.

  The biggest contributor, in addition to Jia Lan's fire, was the stupid Dark Mocha Rat Queen. In order to protect herself, it summoned almost all the descendants of the ruins here.

  Now, there is probably no trace of dark magic rats in the ruins of the Dragon Worship Temple.

  Jia Lan strolled in the rat cage hall, which was still warm, and pondered the source of the power of the fire.

  On the ground of the hall, there are piles of dried bones, rotten fur, piles of dry rat feces and various strange garbage accumulated over thousands of years.

  These natural fuels, plus the corpse oil from the uneaten prey bodies, have already soaked the ground.

  Once ignited, it will be a raging fire that is difficult to extinguish.

  And this complete Dragon Worship Temple, with its perfect ventilation system, makes the entire hall a natural crematorium.

  Cleaning this hall will be a difficult task, and even if it is completed, it will be difficult to use it for other purposes.

  The smell was so strong that it was deadly even after being burned by fire.

  When the hired workers entered and exited, they had to rely on the water blister spell cast by the water mage to protect themselves.

  Unauthorized reproduction: this story has been taken without approval. Report sightings.

  Jia Lan gently pulled out the long combat dagger given to him by Old Jimmy and tapped the blackened rat cage pillars, making a pleasant metal collision sound.

  He glanced at the busy mercenaries, and suddenly swung the knife heavily on the metal pillar, but only scraped off a layer of dirt, revealing the pillar's dark blue essence.

  Jia Lan stretched out his fingers and touched the dark blue metal, and a chill came over him, making him think.

  After thinking for a moment, his eyes suddenly lit up, and he looked around the rat cage hall that was still shrouded in smoke and scorching, and a smile appeared on the corner of his mouth.

  The value of a magic crystal of a Warcraft is almost half the value of the flesh and blood of the Warcraft.

  An unexpected fire devoured tens of thousands of dark magic rats, equivalent to destroying half of the value of the Dark Mocha Rat.

  However, after the fire, the value of the magic crystals found easily exceeded the million gold Taran mark.

  According to the rules of the mercenary world's spoils distribution, most of these Dark Mocha Rat were hunted by Jia Lan, and the spoils naturally belonged to Jia Lan.

  However, Jia Lan generously gave these magic crystals to the Golden Two-Headed Dragon Mercenary Group, both as a reward for the mercenaries' attendance and as the cost of hiring them to clean up the underground ruins.

  In the task list of the mercenary guild, a task of 10,000 gold Taran is already gold-level, 100,000 gold Taran is platinum-level, and a task of 1 million gold Taran is purple-gold-level, enough to support the expenses of a city-state war.

  Although the Golden Two-Headed Dragon Mercenary Group is one of the best in Kelan City, most of the tasks they receive on a daily basis are no more than gold-level of about 10,000 gold Taran.

  Missions worth more than one million gold talans are rare, not to mention in Coran City, even in Zilargo County, or even in the seven continents of the entire Pan-Star Continent. Not every mercenary group has the opportunity to get involved.

  Moreover, even if a purple gold mission is received, the mission process must be tragic, with personnel input, time consumption, supply consumption, and casualties compensation, all of which are not small expenses. It is not as "easy and comfortable" as this time to harvest spoils worth more than one million.

  Even better, this is a private commission that has not been approved by the Mercenary Guild, and there is no need to pay a 10％ commission to the Mercenary Guild.

  Therefore, although Captain Kenmet had some complaints about Jia Lan burning half of the spoils, he still smiled from ear to ear.

  "Cleaning" is different from "repairing" and does not require too much material cost. This mission was originally intended by his uncle, President Clark, to provide free support to Jia Lan, a partner.

  However, Jia Lan not only generously provided a large amount of high-quality potions, but also achieved zero casualties, which made Kenmet very satisfied.

  Kenmet himself felt embarrassed to get so many spoils for nothing, so he led his mercenaries to work extra hard. Even the magicians who were usually treated as treasures were pulled in to work as construction workers to help Jialan's magicians repair the areas that had been opened up in the ruins.

  The always arrogant magicians were very cooperative this time. Upon hearing Kenmet's request, they started working without saying a word. Even the senior fire magician worked hard and helped burn the mushroom jungle with fire spells.

  As for the manpower for repairing the underground city, Kenmet was even more willing to invest. He spent a lot of Jintalan and sent people to hire a large number of hired workers from Kelan City and surrounding towns.

  How many copper dandings are the wages of these hard-working hired workers worth? With more manpower, the cleaning speed will naturally be faster.

  After the rat cage hall was roughly cleaned up and entered, Hugo led a group of elite thieves to continue to investigate the ruins.

  During the cleaning process, the hired workers found that the rat queen did not die under such a fierce flame!

  From the traces, the rat queen used her almost degraded slender claws to dig a deep pit in the garbage dump under the metal cage and drilled into it, and then summoned a large number of offspring to form a layer of heat insulation protection to bury herself, and she miraculously survived.

  A wood magician sprinkled a large number of "corpse-binding vine" seeds on the huge garbage dump, and then gave birth to a large area of ??thick vines, controlling them to quickly devour the terrible garbage dump.

  For humans, the filthy environment in the Rat Cage Hall is difficult to approach, but for plants, this is the most fertile breeding ground.

  The habit of the corpse-binding vine is to wrap the prey with vines into rattan balls when hunting and slowly enjoy it.

  Using this habit of the corpse-binding vine, a large number of corpses of different degrees of decay in the Rat Cage Hall and the layers of rat feces accumulated over the years were collected by the vines of the corpse-binding vine and wrapped into rattan balls of various sizes.

  The hired workers only need to roll these rattan balls out.

  After cleaning up the garbage and feces in the metal cage, the water magicians summoned water balls to wash it vigorously.

  The wood magician who controlled the corpse-binding vine then used the vines to pull the half-cooked rat queen out of the cave it dug.

  What surprised everyone was that there was a circular shaft with a diameter of about two meters in the center of the giant metal cage. It was dark and led to nowhere.

  The Queen of Rat probably intended to dig this shaft to escape, but she got stuck because her body was too fat. In desperation, she could only summon a large number of offspring to act as a heat insulation layer.

  It was this shaft that saved the Queen of Rat from being burned to death by the flames, nor from suffocation due to smoke and lack of oxygen.

  The Queen of Rat's survival consciousness surprised Jia Lan. Nowadays, even rats know to leave an "escape passage" for themselves!
