Dawn of the Grey Tower

Since the physical strength restored by the meal exceeded expectations, the expedition that should have been rested and then carried out could be advanced.

But we still have to wait for the cheese and the cursed crow to clean up the remains of their meal. Speaking of which, this is the first time the two have used the cleaning function in the kitchen. In the past, the gray-robed apprentices only needed to sit down, eat, and then wiped their mouths and left. That's it, the rest will be handled by the blue servant.

And when the two were clearing the plates, they realized an interesting question, where does the garbage in the kitchen end up?

I mean, of course there is a good recycling system for garbage, but this recycling system is not a trash can or something that can be carried outside, but a downward pipe. Its design idea is somewhat similar to today's flush toilets. Throw garbage in, and there will be water flow to take it away and send it into the darkness.

"You said, where will all these things be sent?" Cheese put the plate on and stared at the recycling equipment with his hands folded.

He is no longer a mage who only knows about research. When he participated in the construction of Xigu City, the garbage disposal once troubled Cheese to the point of madness. After all, this era lacks a public sewer system sufficient to support a large population. It is no exaggeration to say that there will be various excrement and wastewater on the streets of many so-called big cities. Most of the diseases of this era also come from this.

The reason why Cangshi is in better condition is mainly because the cold climate is not conducive to the fermentation of garbage and the breeding of scavenging insects. In addition, another example that has completely solved this problem is Riverrun City, but that is achieved entirely by relying on the advantages of water towns and discharging all garbage into water bodies regardless, which is neither easy to imitate nor worthy of praise.

As for the City of Laws? Their planning has already exceeded the limitations of the times.

"There is no place like a landfill outside the tower. I guess it is underground. But if there is such a big hole in the underground of the gray tower, we should have noticed it a long time ago." Curse Crow said after a little thought.

In order to experiment with various spells, the gray robes have inspected the gray tower from various perspectives, intentionally or unintentionally, but naturally they did not see any unreachable hidden space hidden under the gray tower.

Otherwise, with the spirit of exploration of these gray-robed apprentices, even if it is really just a septic tank, they will try to take a look. So as soon as the cheese said, the cursed crow realized the other party's doubts.

"Then let's start here, the teacher can't be in the kitchen

As the cheese said, he took out a stone engraved with runes and threw it into the black hole. Relying on the runes on it, he can sense the position of the stone within a certain range.

"I just hope it doesn't turn out too disgusting, it's not a good meal, but I hate throwing up even more."

The conjurer is used to the way his companions behave, and it does make sense for cheese to do so. Now that there is an undercurrent in the gray tower, if their expeditions are carried out in the functional area, they will easily encounter fellow disciples, and there will inevitably be a risk of leaking news.

And since the object of exploration is the gray tower, most of the secrets in it are also related to each other, and maybe even the garbage disposal system itself is part of the secret. Anyway, I don't know where the key point is, and it doesn't make any difference to cut in from anywhere.

"Okay, it's starting to move. Let's follow." There are many positioning spells, and the one that directly uses items engraved with runes to locate them should be regarded as the most accurate and effective type of spells.

It's just that most of the time the target people want to track doesn't have a clear shape, or it's too late to leave a complete mark on it that can be tracked by magic. Cheese made these stones, and the original purpose was not to really track them, but to explore the depth of caves or pools, and some winding corridors that could not be judged. So now, the feedback from the stone is very clear.

The two were still in the kitchen at first, but soon Cheese's induction went beyond the scope of the room and moved towards other parts of the gray tower. He didn't choose to leave immediately, but tried to find if there was a secret door in the kitchen, but of course he found nothing. The two can only leave the kitchen according to their location, and then leave the dining room, searching for directions in the tower.

Fortunately, most of the gray robes are now attracted to the library, and they have not encountered any obstacles along the way. The cheese and the cursed crow went through one door after another, through one familiar or unfamiliar room after another, and finally reached the end.

"Now I know where everything we eat comes from."

Cheese jumped down from the tubular passage, looking at the scene in front of him and couldn't help but say. No one would have thought that among the many rooms in the gray tower, there would be a whole greenhouse inside. Not only are various edible crops grown in this greenhouse, UU Reading www. uukanshu． There are even ponds for raising fish and some pens for livestock.

It's just that they haven't been taken care of for a long time, the plants grow out of order everywhere, the water in the fish pond is also covered by algae, the fence is broken and loses its function, and the animals that were originally raised in it are missing.

"It seems that all the **** we throw away is turned into fertilizer here."

Cursed Crow pointed to a large barrel not far away, or a windmill-like building, which was connected to the outside of the greenhouse and was obviously some kind of collection device. The direction guided by the cheese's rune stone is in it.

Cheese walked over and began to check the structure of the building. Since the restaurant of the Gray Tower has not been in operation for many years, the building is unexpectedly clean. The vine man plant drilled in along the opening, absorbing all the nutritious substances inside.

"It looks like it should be some kind of mixing device. It will smash the garbage into a paste and then discharge it into the soil. It should have been managed by Ah Fu before, and it became like this after it disappeared."

Cheese disassembled several outer walls of the building to confirm its mode of operation and purpose.

"I thought that what we ate before was all created by magic, but now I feel a lot more at ease. However, the teacher can cultivate a greenhouse here, which is powerful enough."

There is nothing on the ice sheet except snow and stones. Even if it is a gray tower, its internal environment does not support the survival of green plants, which is the main reason why there are generally no green plants in the rooms of gray robes, let alone pets.

"Indeed, very powerful."

Cheese looked at this fertile land that appeared in the wasteland, and whispered softly. The growth of plants and animals is inseparable from energy. Behind this greenhouse, there must be something maintaining it.

For no reason, he thought of the energy core inside the City of Ten Thousand Laws.
