"What's more, this method of digging tunnels is not as difficult and dangerous as you think. Al continued.

He was also inspired by the bank robberies on the planet and came up with the idea of digging tunnels. On earth, there is no more heavily guarded than the bank, and the only way to circumvent the bank's protection is to dig tunnels without using violent means.

And many of the most famous and particularly serious bank thefts on the planet are authentic crimes, and this is a successful precedent.

And this is exactly the same problem that Al and the others are currently facing. They are all heavily guarded. It's all about trying not to use violent means, and trying not to arouse suspicion, and there is no better way than to be authentic.

"Digging tunnels elsewhere will definitely not work, it will be discovered by the Shadow Clan, and we will dig here. Al pointed to his feet, "This is now equivalent to the territory of our Moonlight Clan, and no one from the Shadow Clan will come, so it's best to hide people's eyes." ”

The matriarch and the other elders looked at each other, their first reaction at first was "impossible", but now listening to Al, there is really some hope of success. It can be seen that Al did not come up with an idea with a pat on the door of his head, but after careful consideration.

"It's just that if we want to implement this plan, we need to overcome several difficulties. Al drew a few more bars on the ground.

"What are the difficulties?", the matriarch asked.

"Number one, who among you have dug tunnels, and who has expertise in this?", Al asked.

The Dark Elves looked at each other and shook their heads at each other, "We've all been dealing with plants and animals all our lives, and digging tunnels is what those dwarves are good at. ”

"Why, do you need any expertise as well?", one of the elders asked, "Isn't it okay for us to use earth-based magic?" no matter how hard the rocks in the ground are, they can be solved with magic like quicksand. ”

"You're thinking too much about digging tunnels. Al shook his head, and he pointed to the ground again, the line he had drawn earlier.

"This cave of ours is not close to the cave of the Shadow Clan's Guanren, but it is not far away. But it takes some time anyway, and it's not as simple as living next door and digging a hole. ”

"For such a long distance, if we didn't calculate the angle when we dug it, wouldn't we dig directly into the ground of other caves? ”

The Dark Elves thought about it, and it was indeed the truth. They had never dug tunnels before, but they thought it was too simplistic.

"Mr. Al, since you've already thought of it, you must have found a solution, right? ", said the matriarch.

She knew that Al was a person who planned and acted unless he had to, and now that he had put forward such a plan, he must have considered all aspects.

Al nodded, "This requires mathematical calculations, but unfortunately I don't either, not to mention that we don't have professional measuring tools right now." He knew that these dark elves didn't understand what mathematics and measuring tools were, and he didn't like to explain in detail, so he said two vague sentences and skipped this point directly.

"So we have to use the stupid method, which is to correct it all the time. Whenever we dig a certain distance, we correct the direction we dig against that cave so that we don't end up making a mistake. ”

"That's okay, anyway, we've already seen everything we should be here here, and we have nothing to do these days, so we just want to do it. ", the matriarch clapped.

Al nodded, and drew a second bar on the ground, "The second point is the reinforcement of the tunnel. This tunnel is not something that can be ignored as long as it is dug, if the soil under the ground is a little loose and cannot support the weight on it, this tunnel will collapse. When the time comes, let alone save people, we will all be buried in the ground. ”

"This ......", the dark elves were stunned, they hadn't thought about this before.

"What then?", asked Nightingale briskly, she was now very enthusiastic about digging tunnels.

"Generally speaking, we humans use wooden planks to fix them to the tunnel as a reinforcement. Al said.

"That's not going to work, it's not on the ground, where are there so many planks. The nightingale said immediately.

"I'm not done. Al was a little helpless, "It is better to reinforce it with its practical processed rocks." Stone is harder than a plank. ”

"We humans use wooden planks because they are lighter to use and easier to attach to the soil. But if you're using magic, that's not a problem, and rocks work better than wooden planks. ”

This is Al's greatest reliance now, and it is also the source of his confidence! If in human society, where would so many mages come under his command, and make him plasterers, digging tunnels in the earth? Only these dark elves, each equivalent of a mage among humans, can complete this project in a short period of time.

"The third point, and the most important point, is what to do with the dirt that has been dug up?", Al drew a line on the ground again.

"We can't transport so much mud to dispose of outside, otherwise it's too strange, and the Shadow Clan will suspect us right away. ”

"And the way I thought was to pile it directly in the cave and use magic to turn it into stone and inlay it in the surrounding stone walls, so that it would not arouse suspicion. ”

"But this cave is not big in the first place, digging from here to the cave of the Guanren, the amount of soil dug out is quite a lot, if it is all piled up in the cave, I am afraid that this cave will directly reduce the area by more than half, if someone enters the cave, they will immediately notice that something is wrong. The matriarch immediately thought of the disadvantages of this method.

"Indeed, but didn't I just say that some rocks are dug in this cave to be used to reinforce the tunnel, and then the excavated earth can fill the place of the stones. ”

"It's still not enough, it's definitely going to take a lot more to dig up the soil. The matriarch shook her head.

Al nodded, "That's true, so we're going to take a multi-pronged approach. Then he stomped his foot.

"We turned the dirt into stones and piled them up in the cave, but we didn't do it too much, so that it didn't cause too much change. We lay the rest on the ground. This can cause the ground to be too high, but the average person won't notice this. ”

"If possible, we can take some dirt outside and dispose of it. In this way, we should be able to dispose of the excavated dirt without arousing suspicion. ”
