Coming out of the old goblin's room, the stubborn rock had an extra dispatch letter in his hand, and a puddle of flesh and blood behind him.

Because the management of the hard labor camp is personally in charge of the Bone Demon Guard of the Security Station, the rules here are quite strict.

If there is no letter from the supervisor, even the overseer of the camp cannot wander around at will.

"A group of half-orcs," looking at the instructions on the dispatch letter, Stubborn Rock communicated with the Sword Soul Demon in his heart, "It seems that your value has really been affirmed by that old goblin. ”

Due to the heavy manual labor, the most popular men in the camp were all those of the powerful race.

As close relatives of orcs, half-orcs have a strong physique and a slightly better brain, which is why they are favored by many overseers.

"It doesn't matter, it's ...... that matters"

“...... Find the central device of this traction city," Stubborn Rock mentally interrupted the words of Sword Soul Demon Regis, "However, these orcs are actually quite important, and they will be of great use to you and me. ”

Walking to the door of the barn where the hard laborers were held, Stubborn Rock walked to the sentry and handed over a letter of dispatch to the bone demon who was on duty.

The other man glanced at him—the devil's senses were so acute that he could easily detect that he had just killed someone.

However, on the dispatch letter, the fire paint and signature were both complete, and although the bone demon was suspicious, he still sent a team of barbed demons to the barn house to bring out the orc laborers.

According to the rules of the overseer taking over the new hard labor, Stubborn Rock took the group of orcs to the "torture hall" next to the camp, and he simplified the method of using torture to kill chickens and monkeys, stretched out his arm, and directly pinched the head of the orc leader.

"Those who obey live, and those who disobey die." ”

For a moment, all the orcs were silent, and then they shouted in their throats that they would obey the orders of the overseer and never give up.

And Stubborn Rock just smiled grimly.

After completing a job, the camp overseers go to the "Mission Hall", where they receive new tasks.

Due to the existence of a deal with the Sword Soul Demon Regis, the Krunan Stone Man quickly selected a suitable job. Before the old goblin's death is discovered by others, he must enter the center of Traction City with the golden lamp staff, or he will have to flee as quickly as possible.

In fact, when he allocated the movable type lead plate in the "mission hall", but he couldn't find the tasks related to the control center, he already retreated in his heart.

"Damn, not at all...... Huh?" his gaze was suddenly drawn to the molten lead words, and the stubborn saw a new task offered by the damage management team, "Add lubrication to the gears that control the center......"

Without thinking about it, Stubborn Rock immediately took out his overseer badge and applied for this task as soon as possible.

Of course, when facing the Blood Armor Demon who was in charge of the mission, he controlled his emotions like a rock, and did not show any anxiety or joy. With a calm face, he took the mission description and the map of the work location from his hand.

"Everyone, listen to me, this is an opportunity to work hard, work hard, you don't have to eat nutritious soup today, everyone can eat a fried soft meat!"

The so-called "fried soft meat" is actually a sour mist worm fried in oil, which is rationed daily by every city citizen.

But compared to the "nutritious soup" made from organic residues, it is undoubtedly much tastier, at least it can taste meat in the mouth.

Therefore, when the stubborn rock walked out of the "mission hall" and announced the "good news" in front of the orc laborers, in an instant, they all boiled and seemed full of energy.

"It works out pretty well. ”

Looking at the team of orcs who were carrying lube barrels and were so anxious to run away, Stubborn Rock said silently in his heart.

It's his old way. Whenever he was faced with a difficult task, he would always draw the same pie for his servants.

Anyway, when the mission is over, most of those hard laborers will die. Even if there are people who have escaped death, they do not dare to find him for theories.

Because of the supporting documents received from the "mission hall" and the route map, the stubborn rock led the team to the work site smoothly, and there was no embarrassment on the way.

"Who's coming?"

"The overseer of the penal labor camp is stubborn. ”

"The gearset of the engine needs to be lubricated, your manpower Hisense, but you have to make a mission description for the hard labor in advance, don't come back and get stuck in the gears, and you have to find someone else to clean it up." ”

"Clearly understood"

After handing over to the majestic Blood-Armored Demon Gatekeeper, the Stubborn Rock Belt and his orcs worked hard to enter the engine room.

The alloy gate fell behind him, the airtight valve spewing out a "hissing" steam that wouldn't open again until they had finished lubricating the gears.

At first, Stubborn Rock was worried that he had been recognized, so he was a little anxious, worried that he would be treated as a turtle caught in the urn.

However, when he saw the huge gear set that meshed, all his worries were left behind.

They—he and the golden lamp staff who called himself "Regis" made it to the central device of Traction City.

Although it seems too coincidental, it all went a little more smoothly than expected, but the scene in the engine room is very real.

"We're in luck," Regis' voice rang out from under the heart of the Rock, "I'm pretty sure none of these mechanisms are illusions. ”

As a Sword Soul Demon, Regis has a true vision that ordinary demons don't have, and as long as he is still attached to the Golden Burning Lamp Staff, no illusion can hide his perception.

"You put me on the cog as close to the center as possible, and soon we'll be in control of this moving city, but ......"

"Just what?" said Stubborn Rock's heart tightened.

"I need some time, and it's up to you to fight for me. After adding lubricating oil, at least half an hourglass hour is required. ”

"Sure enough, at the last minute, I still had to go the extra mile. Stubborn Rock pursed his lips, but didn't say much.

In fact, after taking over this task, he had already anticipated all kinds of possibilities, and he had already made plans in advance.

But first, he still needs to command the orc laborers and start replenishing the massive gears with some lube.

The size of the parts of an engine capable of powering a city is unusual: even the smallest gear is more than the height of two half-orcs.

These gear sets mesh and rotate, driven by the engines hidden in the deepest part of the engine room, and propelled the traction city with a surging force.

The bumps in the march and the running-in of oneself will always make some gear sets gradually mesh less tightly, and friction is inevitable.

In this case, someone must apply a protective layer of lubricants. Otherwise, friction not only generates a lot of heat, but it can cause mechanical failure due to the melting of gears, and it is even possible to generate dangerous static electricity due to the build-up of electric charges.
