With Lal leaving, the venue was surrounded by a group of men in black, and the owner of this area finally appeared. The long silver-white hair, the bumpy figure, the board that seemed to be in his hand, and the standard black gown, with the long skirt dragging on the ground, did not seem to affect the pace of the beautiful hostess.

"Good evening, ladies and gentlemen. Because the owner has something to do temporarily, this investment promotion will be replaced by me. So what can come to me. Please keep drinking and have a great evening. ”

There seemed to be nothing else to say, and the beautiful lady opened the door of the room she had come from without looking back, and walked in, leaving the merchants in a daze.

It didn't take long for the hostess's door to be completely closed, and the person in charge of the music, picking up his instrument, stirred up the crowd once more, and the awkward atmosphere was quickly dispelled by the enthusiasm and noise of the music and the cheerful atmosphere.

Dellas, who wasn't partying like everyone else, just sat down in front of the water bar and chatted with the bartender.

"This little brother, do you say that your master is like this every time?"

"This grandfather, I don't understand what you say."

The bartender, who was wiping his glass, stopped what he was doing. He hung the clean goblet on the cup holder on top, took another cup and continued to talk to Dras:

"This lord, about the words of the lord, according to the rules, the people we were hired are not very clear. You'll have to ask Dana-sama for details. ”

"Hehe, little brother, I'm really sorry, so let's talk about something else. Little brother, what are the clothes on your body made of? ”

"Cotton. 100% cotton. ”

"How is this made, even a played spinning machine cannot make every thread so delicate and tough. Look at this outfit on me. ”

Dellas pulled the corner of his clothes in front of the bartender, and pointed to the lines woven on the clothes to show him: "You see that this horizontal line and the straight line are completely two thicknesses, even such an expensive garment, it cannot be changed, do you know what the reason is?" ”

"Master, don't embarrass me. Before I came to work, I was a serf digging in the fields, and my clothes were leftover from generations. Where do I understand this. ”

"That's right, but don't underestimate the difference in thickness, this is completely related to the foundation of industry, for example, the difference between the place where cotton is produced for generations and the place where hemp is produced for generations is very large. And the gap between these two fabrics is not a little big, so there is a place for us traders. ”

"To the master, this is called the starry sky."

The bartender served the wine in a dark blue base with edible gold and silver leaf, and the wine in the goblet was as colorful as the starry sky in the night.

"Oh roar, this is all such a beautiful wine like a work of art, how the hell is it made."

"This is the wine that came down from the Moon of Doom."

"Oh oh oh Moon of Doom, then again, everyone from Dinecol here is talking about the Moon of Doom, what the hell is this Moon of Doom?"

Dras took a sip of the wine called Starry Sky, and the first thing that he had never tasted before was that he had never tasted a strong fruit flavor that filled his mouth, and then the strong fruit mixture lingered in his throat after swallowing.

"The Moon of Doom is what we said earlier, the Moon of Calamity, the Fang Moon in the sky."

"Hahaha, how is that possible. Brother, what are you kidding? ”

"I'm not kidding you."

"Really?"

"Really!"

"Little brother, is it really okay to tell me this kind of secret?"

The guy at the bar looked at Dellas inexplicably.

"But it's never a secret."

In the toilet, Dellas escaped into it under the pretext of avoiding embarrassment. Even the toilet is completely different from the aqua toilet on the ground, after using the toilet, there will be a clean water source that looks completely drinkable to wash away the dirt that you have removed, and there are many moving pictures in the toilet to remind the toilet users how to use the toilet.

Derras was never stupid, she was smarter than the average person. A long time ago, there was a cholera death in the village at the foot of the family castle, and Dras had found the source, but the ignorant people never believed him, preferring to believe the quack doctors' prescription to mix mouse feces with boy urine and drink it into their stomachs.

They are also reluctant to purify the filthy water that drains from the castle. At the urging of Dras, his father, the lord of the castle, agreed to force these ignorant people to start drawing water from the clean upper reaches into the village, and since then there have been few large-scale epidemics.

Water is the source of life, and if it is polluted, it means losing life, and Dras wonders where the pipes that come out of the walls are connected. When he got back to the bar, he found the guy at the bar.

Dras, who had learned the lesson, took out a kingdom gold coin this time, quietly stuffed it into the palm of the bar boy, and said his thoughts, who knew that the bar boy just smiled, and then returned the kingdom gold coin to Dras, and beckoned the dwarf in charge of the water source system. In this way, under the leadership of the dwarves, Drass saw such a large water supply system.

"I didn't expect anyone else to be interested in the water system, you're such a weirdo, but I like it."

"Let's start with the basics. You see, sewage and clean water are separated. ”

The dwarf led Drath into one of the building's control rooms, dazzling him with the myriad of glowing buttons. Several huge screens are monitoring the huge pipes, as if using a crystal ball to spy on the distant situation.

"You see, this is the Dragon and Tiger Waterfall, our city is in the valley, and there is a stream of the Rift River passing through here, and such a spectacular waterfall has been formed due to the huge drop, but don't underestimate this waterfall, this is the most important thing."

"Could it be that a waterfall purifies the water?"

"Tsk, that's why it's hard to teach you natives who haven't studied. Waterfalls have kinetic energy, and if there is kinetic energy, it can generate electricity! ”

"Electricity? The lightning in the sky shot by Thor, the god of thunder? ”

"Something that means, it can drive a huge pump, and then pump the source water from the river into a huge tank, and after so many processes, after a small pump, pump the water to the storage tank on the top floor of the building, and then use gravity to naturally pressurize the water. Eventually, every faucet, the thing you've been playing with, will have a clean water coming out. ”

"This is a miracle."

"Phew! This is called science, science does not understand! ”

Drass and the dwarves spent the night in the observation room discussing the issue of the water source. When Drass was woken up, he found himself surrounded by leftover roast meat and a large number of beer cans, and the dwarf in charge of the water source was still asleep. It was the guy who came to wake him up and was in charge of bartending before.

"I'm sorry. It's too fascinating to study. ”

Drass quickly got up and looked at the embarrassment and the traces of vomiting on his body, and the dwarf woke up at this time, rubbing his eyes and seeing what was in front of him. Immediately saluted respectfully to the bartender brother.

"I have seen the Lord of Doom"

"Lord of Doom?"

Dellas was a little incredulous. Looking at the young man in front of him, who was less than thirty years old, he couldn't imagine that the bartender who had been chatting all night last night was actually the owner of the Moon of Doom.

"Congratulations on passing my test, Lord Dras, I suggest you get some rest today, and I'll arrange a meeting with you tomorrow to discuss the contract."

Narrator Jun showed a slight smile, this merchant was very much in line with his standards, and after finishing speaking, a little face that was tilted at the door was tilted: "Oh, isn't this the mortal who gave me delicious food." It turns out that you are the chosen one. Now it's interesting. ”
