Navigating underground is not an easy task. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 infoThere are a lot of things to think about - lighting, ventilation, the solidity of the surrounding soil - and while these can be solved by magic, flying dust cannot be disposed of with magic. Phantom frowned and covered her mouth and nose with her long sleeves to keep dust out. She steered the drill in front of her all the way forward, the ground was not very flat, but it was no problem to walk. Not wanting the sand to get into the cloth shoes, she floated lightly in the air, flying forward.

The sound of the drill bit is not small, and in order to avoid being discovered, the dream deliberately made a soundproof barrier to separate this place from the outside, so that the sound will not be transmitted.

Ivers looked completely calm. Dream had already explained the battle plan to him, and he only needed to complete the most crucial step.

Dream's attention was always on one of the windows she had open. This window shows where they are relative to the ground. On the one hand, it is to be able not to dig away and dig far, and the other reason is ...... The surface man's moat is also quite difficult to deal with.

It takes a lot more effort to dig deeper, so the dream doesn't make the tunnel too deep, just to the extent that it won't be discovered by people on the ground. However, if you keep going at this depth, you will probably get into the moat, which will be troublesome.

When she was still some distance from the moat, Dream adjusted the depth of the tunnel and began to dig downward, and after digging for a long time, she finally reached a relatively safe depth.

"Phew, I've finally passed the moat. Dream breathed a sigh of relief, "If water suddenly comes out, it won't be easy to deal with...... Luckily, the magicians didn't use any large-scale magic, otherwise they might have collapsed. ”

"Dream-sama, why did you stop, are you tired?" Ivers saw Dream's footsteps stop.

Yes, you can't just go forward like that. Dream sighed, and it was time to think about what lay ahead, and what to do.

After crossing the moat, it's almost underground for the surface people. The dream needs to gradually dig tunnels in a spiral upward, after all, Ivers can't fly, and he can't do anything without being down-to-earth.

However, the surface people must have set up some defenses in the foundation - the dream did not guess what it would be, because guessing was useless. There were no clues, no one knew what was there. You can't say it yet - if you say it, you'll be worried.

However, now we have to bite the bullet.

After taking a few deep breaths, Dream started the drill and continued to move on. She began to spiral upwards towards the surface, much farther away, giving her time to think for a moment.

It is absolutely impossible for a surface man to take the defense of the surface lightly. In that case, what are they going to set up? Something foolproof...... And, it should be used against magic.

After all, in their eyes, the mages are much more threatening than the mercenaries.

Could it be that they buried a layer of metal in the ground?

No, it can't be. Phantom Dream shook his head, the area underground is quite large, they can't have so many metal plates.

So what could it be...... The dream fell into thought.

Suddenly, a loud bang interrupted her thoughts, startling her.
