Leonard, Sheldon, Howard and Raj, four good friends came to David with a box in their hands, and their faces were full of joy.

"We succeeded, look!"

David looked at a few people wearing a few thin coats, didn't rush to look at the things in Leonard's hand, and beckoned a few people to hurry to the cafeteria: "Let's go to the cafeteria first, if you say it here, you will all be cold." ”

"I think David is right." With no women around, Raj can speak normally, and he is also the first to realize that the temperature is too low. After all, he comes from a very hot country, and now he lives in a region where the seasons are like spring: "One more minute I will become an ice sculpture and stay on this land forever." ”

"In that case, you might become an iconic attraction in Winter Village." Howard assumed a frozen position, then rushed into the cafeteria with his shoulders trembling.

David and Mark finally followed a few people into the cafeteria, where the four had already sat down at the bar and asked Jonah for hot soup or a drink.

David didn't rush to urge, and waited for a few people to drink hot drinks one after another, and only after they warmed up did they ask, "Have you already studied how to use the energy in the crystal ore?" ”

"Yes." Howard brought the box Leonard was holding in front of Davy and opened the lid on the box so that David could see what was inside: "It's actually very simple, not as complicated as we thought before. ”

David looked down, and inside the box were some very simple wiring, and at the end there was a light bulb - this thing, anyone who went to elementary school had seen it and even made it himself.

As soon as this thing came out, David understood what Howard was trying to say: "You mean, you can use crystal ore as a battery?" ”

"Uh-huh~" Howard took out a small piece of crystal ore, put it into the special card slot, connected the switch that was originally disconnected, and the light bulb really lit up: "Durable and stable." ”

"It's that simple...... How did you find out about this? ”

David just asked casually, but he didn't expect this question to make the smugness on Howard's face disappear quickly, and he replaced it with an embarrassed expression, and muttered in a very unnatural tone: "Put the crystal ore into my lightsaber as a battery......"

“……”

It sounds like something Howard would have done, and David is glad that Howard just wanted to use crystal ore as a battery for the lightsaber, not something else weird, otherwise he wouldn't be able to look directly at this kind of good thing that can be used as an energy source, a weapon enhancement material, and even a main raw material to make weapons.

"Anyway, we finally know how to use the energy." Howard felt he could make a big difference, and he could design a series of devices that would use crystal ore as an energy source to usher in a new era for Winter Village: "Winter Village Chief Engineer, Howard Wolowitz, sounds good! ”

"It's Winter Town...... If David wanted to, he could just change the name to Winterfell. ”

Everyone turned their heads to look at the voice, only to notice Edwin Van Cleeff, who was eating next to him with a child, and judging by the food in front of him, Van Cleef should have been sitting here for a while.

"Edwin."

"David."

The two nodded and greeted each other, and David greeted Edwin's daughter Vanessa Van Cleeff, and the little girl waved happily to David.

For Vanessa, she didn't know why her father kept moving with her, but after coming to Winter Village, her father told her that she would not move again, and the girl was very happy when she heard the news, so she had a good impression of David, the person who kept her family from running around, and would wave warmly every time she saw her.

"Hello, David!"

"Hello, Vanessa."

After saying hello, David did not ignore Edwin Van Cleef's previous words, although he didn't want to disturb the family time of other fathers and daughters, but Edwin Van Cleef had already put on a posture of 'come and ask', and he couldn't pretend not to see it.

"The design plan for Wintertown has come out?"

"Just sketches." Van Cleef took out a notebook from his arms: "I thought I'd go to you to discuss it later, but since I've met ...... You don't have anything to do right now, do you? ”

David glanced at Howard and the others next to him, who were staring curiously at the notebook in Van Cleef's hand, and it was obvious that they also wanted to see the construction plan for Winter Town.

"No, let's take a look!"

Moving from the bar to the empty long table next to it, Van Cleef opened the notebook in his hand and placed it on the table, introducing his design to David, who was standing next to him, as for the sketches drawn on the notebook...... That's just a sketch, and you can only get a rough outline.

"I'm planning to build a Winter Fortress here, just north of the current Winter Village, next to the current location of the village." Fortunately, everyone present has enough IQ, and with Edwin Van Cleef's explanation, they can already understand the various plans on this sketch: "Build the entire Winter City with Winter Fortress as the core." ”

According to Van Cleef's plan, Winter Fortress is the core area of Winter City, a multi-purpose fortress that includes the castle. In addition to being the lord's residence, garden, and library, it also houses the town hall of Winterfell, various offices, summoning foreign guests, and holding meetings.

As a fortress, there is also a separate military camp inside the Winter Fortress to facilitate the stationing of soldiers, and there are also stables, blacksmith shops, warehouses and other facilities.

“……”

Listening to Edwin Van Cleef's explanation, David felt that this so-called Winter Fortress alone was more complete than the Winter Town he wanted.

"The Winter Fortress has complete drainage and sewage facilities to ensure that there will be no water accumulation on rainy days."

After giving a general introduction, Edwin Van Cleef looked at David and wanted to ask David's opinion, but he felt that his design was perfect, and once the Winter Fortress was built, it would definitely be a more perfect castle than the Stormwind Fortress.

And because of his experience in building Stormwind, if David can get the right materials, he can also ensure that Winter Fortress has good defense against the invasion of mysterious forces.

As a result, Edwin Van Cleef didn't wait for David's praise before he was stirred up by the few people next to him.

"Is water, heating and electricity considered?" Howard looked at the scribbled drawings on Van Cleef's notebook and tried to find the plan for laying the lines: "And how did you plan the sewer pipes in the bathroom?" ”

"Have you considered the network line?" Sheldon also interjected: "Even if there is no global network, there should be no problem with the local area network?" I'm going to set up a couple of servers. ”

......Edwin Van Cleef, who was a little dizzy after being bombarded by a few people around him, found that the situation seemed to be completely different from what he thought, and he found that he had overlooked many problems.

He had actually seen running water and heating, but he didn't think there was any conflict between these things and his own design.

But when Howard, Leonard, and Sheldon, who gave him a lot of headaches, kept pointing out all kinds of problems, he realized that his design concept seemed to be seriously backward and could not adapt to the situation in Winter Village.

Asked carefully what the tap water system was all about? What about the power supply system? Coupled with the 'sample' that Howard was carrying next to him, and when he understood that the power supply system was to expand that little thing countless times, even to cover the entire city, Van Cleef finally realized that he needed to learn a lot of new knowledge.

"It's okay, anyway, the winter in Winter Village is very long, and there is enough time for you to do all kinds of preparations." David didn't complain about Van Cleve's design, and the flaws were only those that Leonard mentioned.

These problems are not that Van Cleef is not inadequate, but that he lacks knowledge of new things and is eager to prove himself in front of Davy.

It's nothing, with Van Cleef's ability, go back and brush up on some knowledge, learn new ideas, and soon be able to integrate those things and make a better design.

"Sheldon, I'm afraid I'm going to trouble you to teach me some new knowledge in the next time." Van Cleef glanced at Sheldon, who was always haunting him and asking him all sorts of headaches: "In return, I'll teach you how to be a real assassin." ”

"Really? That's great! ”

"Oh ~ bad choice!" "That's unwise." "I already have a premonition of what's going to happen next." Leonard, Howard, Raj looked at Edwin Van Cleeff and all looked at 'You're in big trouble!' 's expression.

Edwin Van Cleef knew that Sheldon was 'annoying', but he didn't pay much attention to it, and after planning to start teaching Sheldon how to be a real Assassin and learn some 'modern knowledge' from the other party tomorrow, Edwin left with his daughter.

"How many days do you think Sheldon will survive in front of Edwin Van Kleve?" Howard waited until the father and daughter walked out of the cafeteria, and immediately started the game: "I think one day at most." ”

"Three hours." Raj gave the new unit, and the last two looked at Leonard together.

"That's the leader of the Brotherhood of Defia, the final boss of the Mines of Death, and Sheldon Cooper...... Sheldon definitely didn't live more than half an hour. ”

Sheldon looked at these people unhappily, and was about to say something, when he heard David reminding them: "No matter what, Edwin will not kill Sheldon." However, as a good Assassin, Edwin should know how to use poison to teach Sheldon a lesson without actually hurting him. ”

Hearing David's words, the other three nodded in agreement after thinking for a few seconds.
