The light of the magic lamp brought enough light to the tunnel, and the cloth ducts made of thick cotton cloth coated with slime glue were "whirring" out of the fresh air, and the already slow air flow was spewing out of the air outlet, hitting the rock wall, and then turning and leaving.

"Toot ~ Toot ~ Toot ~"

With three whistles, Charles walked to his station.

An elf was now under the magic lamp behind Charles's side, then looked at the table in his hand and said loudly, "30 meters away, 5° to the left, 7° slope!"

Charles straightened the steel helmet on his head with his left hand, took off his mask and wiped his sweat and put it back on, clenched the EX curry stick with his right hand, and replied loudly, "The distance is 30 meters, the left is 5°, and the slope is 7°!"

"Doot toot!"

The hurried whistle blew, and all the workers in the tunnel were in place, and it was Charles' turn to start work.

Charles first identified the circle marker under his feet, then looked at the mark on the opposite stone wall and took a deep breath.

He arched his front foot and pedaled on his back foot, and his right hand, which was holding the sword flat, was retracted backwards, and a large amount of magic gathered on the sword, causing the EX curry stick to glow with a golden light, and then he stabbed the long sword in his hand forward at a specific angle.

▌??? ≈~━┿? (`▽′?)

A golden bolt shot out from the curry stick, but the magic was no longer like a magic cannon, but turned into a thin line as thick as countless fingers, and then rotated regularly, and a golden spiral twist slammed into the rock wall.

The hard rock was like water tofu cut into by a steel knife in front of the golden twist, and it was cut and shattered by the golden magic wire that was constantly advancing and rotating.

From time to time, there was a slight explosion sound of "bang" and "pop" from behind the rock wall, which was the sound of the explosion produced when the tiny natural magic crystal in the rock wall was destroyed by magic power.

After a few seconds, the golden light vanished, and Charles leaped behind him.

The shattered rock particles and stone powder on the rock wall suddenly poured out with a "bang", collapsing in the tunnel, and a huge cloud of smoke and dust rushed straight to Charles.

Charles unleashed a wall of wind to keep the dust out.

Although he is not afraid of the dust when he wears a mask, it is troublesome to have more dust on the mask and on his body.

After a few minutes, the sound of debris collapsing in the newly dug tunnel had long since stopped, and the smoke and dust began to fall slowly, and no new sound came from inside.

"Toot toot!"

Four whistles sounded, followed by footsteps and carts behind Charles.

The first to take place were a few water tank trucks, and after Charles removed the wind wall, the elves, wearing long beak-like dust masks, began to spray dust from the air to the ground with a water mist.

Then there were elves with shovels and carts, who were the first to shovel the gravel and stone dust that had fallen into the old tunnels and pull them away from the carts.

While there is no more rubble in the old tunnel, a section of rock on the top and sides of the new tunnel has been exposed.

Scargill and a few other old miners came to the outside of the new tunnel with iron rods four or five meters long, and began to hit the rocks on the top of the new tunnel little by little with the iron rods, judging whether there were pumice stones and peeling layers that could cause accidents based on the sounds.

After confirming the safety of the top and sides of the new tunnel, the spirit in charge of clearing the rubble immediately went up to shovel the rubble from the safety zone.

When this section of the gravel was cleared, a team of elves pushing the cart arrived, some of them moved the pre-processed wood on the car to the new tunnel, and then set up support to protect the tunnel and the working elves, and some hoisted a new imported ventilator with a diameter of one meter on the roof of the tunnel, and then connected to the cloth soft air pipe supported by an iron ring to send fresh air to the front.

The elves who are responsible for dealing with emergencies are also ready to deal with accidents such as collapses at any time.

Charles had returned to rest at a later point, where the front command was directing the excavation at the forefront.

He took a bottle of drink and sat down on the marching bed he had prepared for himself to prepare for the next excavation.

Everyone was busy, and no one paid any attention to Charles, except for a stupid bird in the birdcage who looked at him twice.

The bird is a specially trained safety bird in the mine and can provide early warning of toxic gases and infrasound waves before the rock collapses.

After drinking his drink, Charles lay on the marching bed and closed his eyes to recuperate.

At this time, the tunnel had been excavated into the mountain of 303 Heights, and in order to speed up the progress of the project, the elves adopted a three-shift working method, and the construction was carried out day and night.

Charles, on the other hand, rests for about three hours every three hours, and when the newly dug tunnel is cleaned and the roadway support is installed, another excavation is carried out according to the calculations of the construction crew.

Fortunately, there is hard rock all the way, and there is little risk of the tunnel collapsing.

Charles, who was lying down, recalled the "golden twist" he had just used, which was the excavation plan he finally chose after many attempts.

When he first started excavating, he directly bombarded with magic cannons, and as a result, the dust formed by the rocks made him and the elves into terracotta warriors, and the whole tunnel was full of drifting dust, which did not fall to the ground for a long time.

Then he tried to break through the sky, and the end result was similar.

After two days of experiments, Charles finally invented the "Golden Twist", which has the advantages of less dust, easy to clean gravel, and high controllability of the cross-sectional shape of the tunnel.

However, there are also drawbacks, using this trick requires a lot of mental power to control the movement of magic power.

At the same time, controlling the distance and angle of excavation also requires a lot of mental energy.

If Charles's soul hadn't been plugged in, he would have knelt after one or two shots.

Charles felt that his blow just now was a bit too hard, and the distance of this excavation should be a little more than thirty meters, but the angle would not be offset too much.

Now his magic and martial arts are developed and perfected in this continuous study and practice, and by constantly summarizing the lessons and lessons generated in the process of practice, he has updated and improved on the original basis, and made adjustments in the way of solving problems. In the continuous improvement and adjustment, innovation also comes naturally, innovation comes from practice, is the sublimation of practice, in the continuous practice to find the source of innovation.

The sound in the tunnel is not too noisy, because everyone is wearing dust-proof bird's beak masks, and the miners use gestures to convey information.

In such an environment, Charles soon fell asleep.

He had only slept for a short time when he was woken up by the elves.

The newly dug tunnel has been cleared and the surveys have been completed.

The angular error of the new section of the tunnel was within the permissible range, and the distance was almost two metres more than two metres as Charles had judged.

After some calculations, Charles' next excavation had to be a little further to the left, so that the excavated tunnel would be as close to the design as possible.

Woken up, Charles stretched, then discussed the construction plan with the construction crew, and finally stood in front of the rock face again.

He replied to the distance and angle of the tunnel, and then stabbed the curry stick in his hand again.
