The sewer drawings of Feiyun City are classified documents, and they are not known by looking up on the Internet like tide tables, but fortunately Hugo has a copy in the firm's computer.

After a little discussion, the detective and his assistant decided to go their separate ways, with Blue going back to the office to find the drawings, and Hugo saying that he was going to find a mysterious master and ask for help to find the owner of the Super Stone.

"Hugo's temper is so incomprehensible that he deliberately betrayed the Guan Zi and did not tell me the helper he had invited, and mysteriously said that it was someone I had met...... It can't be that Douzi has returned from a trip, right? No, she seems to have wandered to Lichong City in the western part of the United States recently, and she should not be able to return for a while. Besides, that person seems to be better at getting things lost than looking for them......"

Bilan, who complained about Hugo, returned to the Yuqi Mansion, walked through the courtyard, and opened the entrance door of the Yuqi Mansion.

What caught the girl's eye was the detective's grass seedling turtle with a leisurely expression, and it was pouring itself a drink in the living room of the office with a rattan whip rolled in a teacup.

"Caomiao Turtle, are you staying behind today?" Bilan said hello while changing her shoes.

Don't look at the grass seedling turtle left alone in the office, it looks pitiful, it actually shoulders a great mission-

In the past, when detectives left the office in order to solve a case, they would hang a sign in front of the gate outside the courtyard that read "Under Investigation", so that Yuqi Mansion would be temporarily closed.

However, some time ago, the little flame monkeys seemed to have passed the assessment of Detective Hugo, and from then on, they could take turns staying at home while Hugo was handling the case, and was responsible for handling the reception of the clients who visited during this time.

Among the detectives' elves, the little flame monkey and Bogaman like to run around with Hugo, but this grass turtle with no sense of existence prefers to stay in the office, so it often voluntarily changes shifts with the other two elves, and silently stays in the office while the detectives run out of office.

"Caomiao Turtle, do you know where the underground waterway drawings of Feiyun City are placed?"

Bilan only knew that the documents were probably placed near the detective's desk, but she didn't know the exact location, and she tried to ask the grass seedling turtle before starting the official search.

Surprisingly, the turquoise turtle nodded its massive head without thinking about it, moved to a pull cabinet next to the desk, and opened the penultimate drawer with a rattan whip.

"Ah, it's really here!"

Seeing the blue drawings in the drawer, the girl exclaimed with joy.

Since the design blueprint of the sewer is not small, there is a thick stack, so Bilan put the drawings that need to be used into the handbag.

When he was busy working, the mobile hard drive that was originally stuffed in his pocket fell to the ground, and the grass seedling turtle thoughtfully picked it up and handed it back to the detective assistant. Bilan shook her head: "It's a useless surveillance video inside, just put the hard drive on the desktop." ”

The grass turtle tilted its head in confusion, and Bilan casually told the little turtle about how she and the detective were looking for the super stone.

After packing up the drawings, Bilan said goodbye to the little turtle left behind, and took Eevee out of the Feather Mansion like a gust of wind, anxious to know who the master invited by the detective was.

The grass seedling turtle still had a calm expression, it looked at the mobile hard drive left by Bilan, and had its own thoughts in its heart-

Anyway, being idle is idle, so it's better to take a look at the surveillance video that Miss Bilan worked so hard to get.

。

Bilan came to the location agreed with the detective, only to see that Sister Reina found that the slope of the Super Evolution Stone was empty.

Well, it seems that the detective's plan to hire someone did not go well, and he completed the task first.

The girl was not bored, she found a nearby dessert shop with few customers, and flipped through the blueprint of the sewer design by the window of the store.

Of course, in order to avoid her actions being too eye-catching, Bilan also made some concealment measures -

She sent the Changeling Monster to sit across from her in the form of a fighter. In the past, when traveling in the Johto area, the Changeling Monster had seen Douzi, so he could transform into the image of the high-ponytailed energetic girl.

Sure enough, compared to flipping through the thick blueprint alone, the picture of two girls coming together head-to-head in a dessert shop is much more harmonious.

Bilan gratefully looked up at the Changeling Monster who turned into a bucket, this child is simply a universal ace in social etiquette, when she was traveling alone in Guandu, she relied on the skill of Changeling to avoid many embarrassing occasions.

“…… The super stones were picked up here, the slope is in this direction, and the sea is on the south side, so the water level is churning in this direction at high tide......"

Blue studied the map of the underground waterways, but her expression grew to surprise.

"Originally, I thought that the source of the super stone would be the center of the city full of rich people or the wealthy area in the west, but why did it point to the south of Feiyun City according to the direction of the underground water flow...... Isn't that direction a wasteland by the sea? ”

Just as the girl was pondering and reasoning, the "Miss Douzi" opposite her encountered unexpected trouble.

A waitress saw the figure of a girl with a high ponytail, and immediately stepped forward familiarly: "Miss Douzi, long time no see!" Are you planning to order your usual dessert set? I still want to try our new autumn products, and I remember that you said that you were looking forward to it. ”

Faced with the sudden attack, the Changeling Monster panicked for a while, and even its eyes changed back to the Changeling's iconic beanie eyes.

It's bad, I forgot that this was the foraging territory of Douzi, and I didn't expect the waiter to be so familiar with Douzi......

At the moment when the monster was almost exposed, Bilan put down the drawings with a snap, pulled back the waiter's attention, and then said loudly to "Douzi"——

"Of course, it's both a package and a new product, Miss Douzi, I'll pay for this meal."

The Changeling Monster nodded desperately, almost shaking its head out of the afterimage, taking the opportunity to change its eyes back to the appearance of a human.

"Okay!" The waitress happily ticks off the dessert on the e-à la carte menu, "Mango sparkling water with a three-tiered luxurious creamy fruit tart set, plus an autumn-only candied golden chestnut cake." It's ...... altogether."

After paying the bill, the waiter left the table with a satisfied smile.

Bilan's heart is also dripping blood with her wallet - Douzi's dessert set is too expensive, it is worth a few days of Bilan's salary in the office...... Even for a well-paid celebrity trainer, it's too much to spend money like this.

Then, Bilan saw the waitress return to the table with a "mountain" composed of a huge amount of cream and various fruits: "You two have been waiting for a long time, this is the set meal and new products you ordered, I hope you have a happy meal." ”

Only then did Bilan see that at the foot of the Cream Mountain, there was a very small cup of orange-yellow sparkling water, and a triangular brown-black cake.

"Uh......" Blue almost groaned, the weight of this dessert was too much, even if you count Changeling and Eevee.

The sound of the cell phone vibrating came from his pocket, and almost at the same time as the dessert was served, Hugo's call arrived.

The assistant lady connected the phone, and sure enough, there was a report that the detective had arrived at the rendezvous with the helper.

Blue cautiously consulted the detective for advice: "It's lunch time now. Why don't we have a dessert together? ”

Hugo's voice paused for a moment, and then asked in a strange tone, "Are you going to let the Changeling Monster look like a fighter, and then be forced to order a lot of what that big stomach king usually eats?" ”

"Oh my God, Hugo, how do you know? You don't have superpowers, do you? ”

"I have a pair of eyes, blue. Eyesight isn't a superpower, and I'm right outside the glass of the dessert shop right now, and I can clearly see you and your Changeling Monster staring at the buttered fruit three-layer tart in a daze. The detective's voice had a hint of hatred.

The assistant lady suddenly turned her head to look out of the window separated by glass—

Outside the wall, Hugo was standing in front of the glass partition with a somewhat familiar thin old man, staring at her and "Douzi".
