In the early morning of winter, the Black Rock City was completely awakened in a loud and majestic trumpet, with the protection of the city wall, the cold wind and flying snow could not be raging in the city, and the Black Stone people in the city would never have to sweep the snow in front of their own doors, so except for a layer of silver-white hats above the upper floors, there was basically no snow on the road.

The soldiers of the morning exercise in the city ran through every street in the city at a uniform speed, one by one the doors opened, the owner greeted the passing team happily while cleaning, and in the bursts of haggling mist, the entire Black Rock City was full of life and smiles.

In front of the square in the middle of Black Rock City, Lu Ya saluted each of the morning exercise teams and walked down the low platform.

"Last night, I'm sorry," Nina said with some embarrassment as she looked at Ruya who was walking towards her, she was still a little embarrassed about her nagging last night.

"I just didn't know what happened yesterday, and suddenly I wanted to talk to someone, you wouldn't mind," Nina added again as she looked at Ruya with a smile on her face.

"Why, I'm so happy that you're willing to tell me your story, which only a true friend does. Let's go, do you want to run a lap, move your body" Ruya said as she began to jog, and Nina slowly followed after seeing this.

"Friend・・・・・" Nina muttered as she ran.

"What?" asked Ruya, turning his head.

"Oh, I mean, it looked pretty good."

"Hey, handsome," Lu Ya smiled and grinned.

"I'm talking about the running soldiers, not you," Nina laughed.

"Hehe・・・・・"

After running around the outermost street in Black Rock City, Lu Ya and Nina, who were steaming hot, came back, Nina was arranged by Lu Ya last night in a large bedroom specially placed in his city lord's mansion, the two of them went back to take a bath, and only after cleaning up did they gather in the living room, and after a while, the hot breakfast was delivered, and Lu Ya beckoned Nina to dine together.

"Hehe, I really can see that you are rich, I am afraid that there are not many people in the whole of Boulder City who can afford such a sumptuous breakfast," Nina teased at the table full of breakfast.

"You misunderstand me, the food, just enough to eat, I usually don't pay much attention to eating, and the amount is basically only enough for me and them to protect the city lord's mansion personnel, today I saw you coming, I deliberately let them do more, mainly because I am afraid that you are not used to it, if the respected Nina will lose weight after going back, then my sin will be great" After Lu Ya finished speaking, he picked up a small piece of bread by himself, and then sandwiched two small pickles, seeing this combination, Nina couldn't help but roll her eyes.

"Hey, hey" Lu Ya smiled and poured another mouthful of soy milk, he also knew that his way of eating was a bit strange, but what he just said was indeed the truth, he was not pedantic that he had to eat the same as all the other clansmen to reflect how noble he was or something, and he also felt that he should enjoy some treatment higher than ordinary clansmen, and there was nothing wrong with it, but if he was asked to make ten plates and hundreds of plates like those princes and generals, he still couldn't get it every day, one is because Black Rock City didn't have that condition for him to waste now, Sao Bao, the two are also the most important, because he can't eat it either・・・・・・・

In addition, his eating habits that he developed in the past also made him feel that the meals of the other world were not very adaptable, just like this bread with pickles, the bread is also the kind of very rough dead bread, not the soft and sweet bread in the previous life, since there are no steamed buns for him to eat for the time being, he can only make a living with this.

"No, you can give me whatever you usually eat in the future" Nina said lightly and began to eat quietly, Nina during the meal was different from her usual bold and enthusiastic appearance, giving people the feeling of being quiet and generous, and everyone felt beautiful, it can be seen that Nina has been instilled with strict dining etiquette since she was a child.

While admiring the beauty while finishing her own breakfast, Nina also wiped her mouth with a napkin and stood up, after the two got up and left, the little maid who had been waiting next to her just now trotted two steps to greet the door, and after a while, the security personnel in the city lord's mansion walked in with ease, and each quickly found a seat and sat down, and a table of breakfast was divided by them.

Nina, who didn't go far, glanced back at the group of attendants who were laughing and eating in a low voice, and a trace of surprise flashed in her eyes, and Nina, who usually had a deep class concept in her bones, couldn't accept this situation.

After Lu Ya made the sofa in the living room, he said to a maid who was sorting out the water cups next to him, "It's not busy here, you can go eat it quickly," the latter smiled at Lu Ya and nodded, and then continued to pour hot water into both cups and serve them in front of the two, and happily joined the group of companions who grabbed the meal.

As if seeing Nina's surprise, Luya chuckled and said, "Hehe, don't you think it's weird." As I just said, I'm not used to eating alone in front of a table of food, I usually rarely eat at home, except for breakfast here, I usually eat with others in other places at noon and night, even if it is breakfast, I often eat with House, Xiaoqi who said things, they know that my things here are finer, and they are willing to come to eat hehe"

"I eat with them when they're there, and if they're not there, I'll eat with them, and when there's more, it's fragrant."

After Lu Ya finished speaking, he didn't expect Nina to understand him or anything, and sat down for a while before getting up and going out, "Sister Nina, I'll call Xiao Qi to accompany you in a while, I still have some business, go out first" Lu Ya asked the maid to bring her coat and put it on.

"Well, go get busy, don't worry about me"

In the face of Nina's empathetic reaction, Luya really didn't expect it, he originally thought that Nina would have to follow him, so he would definitely not be able to go to his institute, but what he didn't expect was that Nina would let herself go so happily, which was really a little unexpected for him.

Just a few steps out of the gate, Lu Ya met Xiao Qi who was walking with a small mouth, Xiao Qi was also wrapped in thick fur, a fluffy pink fur, it is said that it took a lot of effort to get it by Haust. Lu Ya didn't interfere too much in the affairs of House and Xiao Qi, he understood what kind of temperament the two of them were, and felt that he didn't need to say anything more.

"Shout, what is this stealing, look at the oily little mouth" Ruya joked.

"Hmph, you, a rich man, are so slamming the door, it's good if we don't drink cold water as our subordinates" Xiao Qibai glanced at Lu Ya.

"Drink~ You pot is deducted, don't forget that my money is in the hands of House, why don't you touch your conscience when you speak" Lu Ya replied with an innocent face.

"・・・・・・" Xiao Qi's face turned red as soon as he heard Luya mention House, and finally replied not to be outdone, "Be careful to tell him about you and that Nina when I see Sister Avella."

"Hey~~ My little aunt, what's wrong with me and President Nina, you can't chew your tongue indiscriminately, you have to talk about your conscience when you speak."

"Hmph~"

Seeing Xiao Qi sneaking into the City Lord's Mansion with his little head up, Lu Ya rubbed his nose vigorously, and then walked towards the research institute with a bitter face.

In the midst of the noisy exchanges and smoke in the institute, Luya found the old man of iron, who was sitting around a table with a group of researchers, not knowing what to do.

"What are you doing," Ruya tiptoed and looked inside.

"The patriarch is here, come on, come and see, patriarch" The old man raised his head sharply when he heard Lu Ya's voice, and then pulled Lu Ya as if he was walking.

In a few moments, a large, crude metal ball came into view, hanging alone from a stove, with a crooked cast iron pipe at the top connected to a bucket full of water on the ground. Lu Ya saw it in his eyes, and he recalled it for a moment, and then he guessed with some caution, "Pumper?"

"Yes, it's a pump, Patriarch," the old man said, as he pushed aside a few researchers who were circling around the metal ball, and instructed the people next to him to make the fire bigger, and then continued. Yesterday as soon as the rubber was shipped back, I did the experiment first, this pumping machine is the simplest of the information you gave the patriarch, and it also consumes the least rubber, I used a knife to cut a few gaskets up the pad, and tried the effect, sure enough, it is not comparable to some linen animal tendons, this pumping machine used to run everywhere, and the water couldn't be pumped at all, guess what's going on now, hehe"

As he spoke, the old man gestured to the experimenter next to him, and then one experimenter quickly removed the fire under the ball, and the other experimenter carried a bucket of cold water and poured it on the still hot iron ball.

"Wow~"

"Quick Look"

"The water is gone, the water is gone~"

"Is this the expansion and contraction of heat and cold contraction?"

"This is due to the fact that the internal air pressure is less than the external air pressure..."

“・・・・・・・・・”

Seeing a group of people around the bucket that had been suddenly drained, and a modern term popping out of his mouth from time to time, Lu Ya felt a strong sense of pride in his heart. (To be continued.) )
