The traces of the Silverstone Spell Cellar have been completely erased.

No one can realize that above this huge crater, there was once a "power station" on which the elves lived.

The other buildings were only roughly bulldozed above ground level. Only the spell cellar did not leave a single piece of rubble, and even the part below the ground was cleaned.

This is a huge crater-like cavern, with an internal diameter of several hundred meters alone.

Strangely, the people who dealt with this place did not dig a large vertical hole from top to bottom, but after bulldozing the buildings in the ground, they dug a hole from the entrance and extended it at an angle.

The further down the cave, the larger the size of the cave becomes...... Until the depth of more than 20 meters below the ground, the space has reached the maximum and the depth has reached the deepest.

Further down ...... You can see through the shattered and collapsed floor that glows blue to the sewer at the bottom of the crater, which has become dry, covered with dust and rubble.

“…… It looks like a subway exit. ”

Dove commented on the forum: "There must be at least two floors underground. ”

"It's not two floors."

These words came from the delicious wind goose who watched the live broadcast quietly, and he replied affirmatively: "It should be the fourth floor." As you first went down, I saw a remnant of the floor...... If each floor was the same height, you would now be four floors underground. ”

"It's okay to have a few layers," Citalopram looked at the sewer with some hesitation, "the point is...... Do you want to go down? There doesn't seem to be much here. ”

“…… No one has used it here for hundreds of years, are you still afraid of getting dirty? ”

"No, I mean the drain is too wide. It feels like you can even drive a car to catch shrimp inside. ”

Citalopram complained silently: "This familiar shape...... I always felt that there might be four muscular turtles with murder weapons coming out of it. ”

Dove comforted: "Don't worry, if you really want to jump out of the four green turtles, let's eat bouncing soft-shelled turtle soup for supper tonight......"

"I really don't want to go in, I always feel like there will be rats and cockroaches inside......"

Citalopram muttered.

But having said that, after seeing Bofis float into the sewer, she could only helplessly hold the torch to follow, and couldn't help but complain: "I haven't come in for so long, is the air here okay?" There won't be any gas in this sewer that will explode at the sight of fire, right? ”

"It's not a sealed environment...... It's completely connected to the ground, so apologies to your chemistry teacher. ”

Four secretly complained.

Unlike the empty, completely torn basement, the sewers unexpectedly retain a fairly good intact.

The sewers built by the elves look like huge blood vessels. Reach in all directions in the underworld.

The original waterway in the middle has completely dried up, leaving only a shallow layer of dry sand. On both sides of the sewer, there are clean, walkable bumps.

Although the sewer has been dry for a long time, everyone, including Bofis who has become a ghost, still subconsciously moves along the edge of the sewer.

Dove, in order not to be unconsciously stepped on in the dark, fell to the last place. Anyway, the body of the chocolate has night vision, and it can move forward normally without the lighting of citalopram.

She sniffed the air with a strange expression, and then tentatively rubbed the sand in the middle with her paws, and put it in front of her face to sniff.

Her expression became more and more strange.

She stretched out her paws and dug the middle layer of sand into it like a pit - it was a moist dirt inside.

She took another sample and sniffed it. Then he rubbed his paw on the ground with a thoughtful expression.

Dove crouched in place and thought for a moment, then suddenly ran to catch up with the crowd, jumped up lightly, and grabbed the pants engraved in front of him.

Then she jumped twice and lay on Si Dark's shoulder, like a cat-shaped school bag.

The four were taken aback by Dove's sudden move.

But Chocolate is not a small pet cat - Dove can't squat on the body of the Four Dark Carvings with her body.

Si Darken could only hold the cat a little embarrassed, feeling the weight of this comparable to a bear child.

"What's wrong?"

He whispered to the serval in his arms and asked, "Are you afraid of getting dirty?" ”

"—not."

Dove pretended to meow and calmly replied on the forum, "I checked the sand in the middle. There is no smell of greasy, excrement and rot at all.

"It's a sewer, but there's no stain visible on the walls or floor...... Isn't that strange? ”

"Maybe it's because so much time has passed, and the stain has weathered?"

Four secretly followed Dove's gaze to the sewer: "And after a few hundred years, the smelly substance will not exist for a long time." ”

"That will at least leave a trace."

Dove responded, "If nothing else, the soil will at least become fertile." But I don't see any signs of the soil becoming fertile...... Instead, traces of the curse were checked.

"The sand on the surface, the curse has almost dissipated; But the curse was palpable in the deep wet earth. The concentration was close to the aura of Annan's previous ritual in the warehouse. ”

“…… That's weird indeed. ”

Four thought for a moment, then nodded in agreement with Dove's reasoning.

Citalopram in front also saw the conversation between people and cats, she paused, and without hesitation, she asked directly to Bofeis: "Speaking of which, Bofelite...... What is this sewer used for? ”

“…… How could I possibly know? ”

Bofis turned around, looked at citalopram in amazement, and asked in disbelief, "Do you guys over there need to know this kind of knowledge?" ”

"Cultural differences."

Citalopram said confidently: "It's normal to know some general knowledge, right? And I don't even know what you call it. ”

“…… Even if you say that, there's no way I'm going to know. ”

Bofis felt a little headache: "However, if it's just the level of popularization...... I still know that this is for garbage. ”

"What garbage? Feces? ”

"- Hey! How can you say such dirty words! ”

Bofis is surprisingly not very good at dealing with this type of word.

She retorted with some embarrassment: "How can the feces be discharged into the entrance pipe, it is too smelly in the city!" ”

“…… So where does the water lead here? ”

"On the ground, of course."

Bophys replied confidently.
