As soon as Charles's course of action was submitted, he was immediately hoisted up and hammered by the elves.

"Don't look down on digging alleys, boy!" Scargill, who had been mining in the Crystal City area for longer than the time Monkey King had been crushed under the mountain, squirted Charles with saliva in his face.

In his own field of expertise, Scargill, an old miner who grew up in the mines, did not give Charles any face.

"Do you know the mountain and the geological formations around it?"

"Have you considered the factors that affect the stability of the surrounding rock during excavation?"

"Which shape do you want to choose for the roadway section?"

"How do you solve the problems of support, ventilation and drainage?"

Perhaps it was the reason why communication in the mine could only be relied on by roaring, and Skagill was very good at roaring, and he yelled at Charles for more than half an hour before the meeting began.

Although Skagil's face was full of wrinkles and his short golden hair had turned gray, his resolute eyes, his tiger-backed figure, his knotted muscles under his overalls, and the badge of the Bishop of the Forge Temple on his left chest all showed the incomparable confidence and surging momentum peculiar to the working class.

Beside Scargill is a group of elves who exude the same aura.

Faced with contempt from the working class, the successor of feudalism, Charles Earl McGardenen, could only curl up in his chair and shiver.

He only told some cases of tunneling by hearsay, and never systematically understood and learned how to design and excavate tunnels.

After reading the plan, the officers of Crystal City praised His Highness Charles for his imagination, and then put the plan aside and began to find professionals to plan the relevant matters.

Many of the local officers in Crystal City are the children of the mining area, and they all know how to dig tunnels.

Charles had already arrived in Crystal City with Arethosa yesterday, and now the parties had come together to discuss the feasibility of this unprecedented plan.

On the wall of the conference room hung a huge blackboard, and first of all the military representatives told about the operational requirements and wrote them on the far left of the blackboard.

Next on the stage were representatives of the Geological Survey Department of Crystal City, who brought several boxes of materials.

For an unknown number of years, the Geological Survey Department has conducted geological surveys of the entire area in search of new magic crystal mines, and the targets of this operation are also within the scope of their previous surveys.

The survey department had already made preparations before the meeting, and first the two elf ladies used colored chalk to draw various maps on the blackboard.

Charles couldn't tell anything but the mountain and the surrounding topography and geological formations, and he didn't know what the patterns of the filled blocks of different colors and shapes meant, and he could guess when the water level of the groundwater was in place.

But he saw that Scargill and the miners were staring intently at the diagram on the blackboard, for fear that they had missed something.

The representative of the survey department is an intellectual beauty who is over 600 years old, but her charm is still there, and a pair of small gold-wire glasses on the bridge of her nose makes her bookish aura more and more intense. She held a whip and introduced the mountain and its surrounding geological formations to everyone in the room in a crisp and pleasant voice.

Charles regretted why he didn't put on his mask early today, anyway, he basically didn't understand this professional knowledge, and it was not as pleasing to the eye as this expert from the survey department.

Nothing happened to Charles for the rest of the year, and there was a heated discussion between Scargill and the miners, and from time to time they asked questions of the survey department and the military representatives.

Charles didn't understand most of the technical terms spoken by the elves, so he sat there with a look that he didn't understand but pretended to understand, admiring the beauty by the way.

A sudden argument brought the distracted Charles back to his senses, and then he noticed that everyone in the room was looking at him.

So he calmly looked around the room and noticed a sketch of the alleyway on the blackboard.

In order to cover up what he had just wandered by, he decided not to speak at first and waited for others to speak first.

At this time, Skagill asked, "Your Highness, can you dig a well over there in Wutong City often?"

Sycamore City is next door to Crystal City, and it's been so long, so it's not surprising that Charles is digging a well over there.

A bad feeling suddenly appeared in Charles's mind.

Sure enough, Skajill said, "Because it's rocky, our miners are digging too slowly, and I'm afraid we won't be able to dig up the hill until next year." If Your Highness can use the method of digging a well in Wutong City to dig the roadway, I think the roadway can be dug through quickly. ”

Charles looked at the elves in the conference room who couldn't stop nodding, and sighed in his heart, is this the fate of the curry stick?

Then he sat there and thought.

The output power of the curry stick's magic cannon is adjustable, and if he was able to overclock it at the Altar of the Evil God back then, he could have done it with one shot through that mountain.

However, that situation cannot be replicated, he doesn't have so much magic now, and the power of faith that can be called in the dream platform is not at the level of that time, so he can only take his time.

Usually, the magic cannon he fires in battle is about 40 meters, which is the result of taking into account the strength of the enemy's defenses and his own control.

Judging from the use effect, the magic power of the magic cannon turns everything that stands in its way into powder, and then is blown away by the magic power. If it is used in a closed underground, how to clean the powdered rock is another problem.

In terms of the number of uses, he estimated that with his current strength, digging two or three hundred meters a day was more than enough. But you'll have to dig some at a time, and you'll have to take a break in the middle.

"Yes!"

Skagill said immediately after Charles told the story.

Skagill continued: "We can use the materials available at the mine site and dig a three-kilometre-long tunnel in about 10 days. ”

At this time, the representative of the military said: "If the project is difficult, you can dig the tunnel near the bottom of the lake on the top of the mountain, and then carry out blasting." As long as the water source at the top of the mountain is destroyed, the enemy there will be defeated. ”

Charles nodded, it was a good backup. Let the water source at the top of the mountain leak, and the enemy will not be able to stay there. At the beginning, the street pavilion was out of water, so it couldn't be guarded.

The plan was quickly prepared, and the elves set up a camp in the woods about a kilometer outside the mountain under the pretext of building a stronghold. The miners then dug a hole in the ground in the middle of the camp and put Charles inside.
