Girl??" Xue Rou asked Ling Feng first.

"I don't know, she wears a gauze hat and doesn't say her identity. Fang Tianya replied simply.

"It's almost time to arrive. Tianya, please go pick her up. Ling Feng remembered a person, Lin Yubing, who was "traveling separately" from him.

"Okay. Fang Tianya glanced at Ling Feng for a moment, then turned around and left.

After Xue Rou left Fang Tianya, she asked Ling Feng, "Who is it?"

"Huh?" Ling Feng hesitated for a moment, not knowing what Xue Rou was asking, but he immediately reacted and said, "Lin Yubing." ”

"Lin Yubing?!Why did she come here, and how did you know it was her?" Xue Rou immediately asked, she didn't know that Lin Yubing also set off to Tianxiang after Ling Feng and came to the Imperial City.

Ling Feng replied nonchalantly, "When she was in Beamon City, she said that she would come to the Imperial City and set off on the same day as me. Now that I've been here for five days, she should be in the Imperial City as well. ”

"If she can't find you in the Imperial City, others will naturally tell her that you are here, and then find here. Cheryl added to Ling Feng.

Then Cheryl became very unhappy: "Hmph, why haven't you heard about this matter?"

"No?" Ling Feng asked rhetorically, and then with an expression of nonchalance, "It's not a big deal anyway, it doesn't matter if you know it or not." ”

"What's not a big deal, if she comes, I'll prepare. Cheryl has a look of blame on her face.

"What are you going to prepare, to welcome her, to ask for her autograph?" Ling Feng vaguely remembered that Xue Rou was a fan of Lin Yubing, even Xue Qing, and it was estimated that only Elf and Xue Fei were not interested in her.

"Hmph, you don't have to worry about this. Xue Rou didn't answer Ling Feng, but secretly said in her heart: Welcome!? If it has nothing to do with you, I will welcome it, now ...... Hum!

"That's up to you. Take advantage of the end of the world to pick up people, I will discuss some things with Lao Lin and them, you wait on the side for a while. Ling Feng wanted to take advantage of this spare time to instruct Lin Fanyun and the others to prepare things, as well as the matter of mobilizing manpower.

You don't have much time to spare? The outside that Fang Tianya said was not outside the Lord's Mansion, but outside the Black Stone Mountain, and strangers were not allowed to enter the Black Stone Mountain, and even those who knew him were not necessarily qualified to enter, this was a rule that had not changed.

Therefore, Ling Feng didn't need to ask, he knew that this girl was still outside the Black Stone Mountain, because Fang Tianya said that he didn't know who this girl was.

Time passed little by little, and Ling Feng told the two of them the general arrangement, and the other details were handled by the two of them. At the same time, he also produced a set of drawings that had been prepared to give them an idea of how the shipyard would work, but until then, no one knew that the shipyard was used to build such steel ships.

Finally, take out the drawings of the ship he wants to build this time, and let Locke build the whole ship according to the drawings, and the other decorations and interiors will be started by specialized people when the ship comes out as a whole, and the power system, defense system and attack system will be handled by Ling Feng himself.

"You, are you going to build a ship out of steel, and the entire hull is iron?" Locke looked at the drawings dumbfounded. And because of his words, everyone else stopped their movements and looked at Ling Feng blankly. It had never been heard that a ship could be made of iron, not because they didn't have the technology, but because they never thought about it.

"Yes!" Ling Feng nodded.

"So you mean this when you say water fortress. Locke said dumbfoundedly, just now Ling Feng said about the water fortress, he thought that it was to build a fortress in the Black Rock Lake, which was fixed and not this kind of movement. As for Lin Fanyun and Xue Rou, they are all the same, they all have the same idea as Locke.

"Of course. What do you think I'm talking about?" Ling Feng understood that Locke might not be able to understand this matter at once, so he explained: "Iron ship, in the past, no one had built it because of so many materials and no welding technology. And now that everything is ready, we will make history and build the first ship of steel. Not only that, but we're going to build a second, a third, and many more. ”

"Make history and build the first steel ship...... Locke was in a state of excitement after listening to Ling Feng's words, if he really did, then Ling Feng's words would become a fact, then he would not become one of the founders of the steel ship.

Excited......

Merely......

"Long Tian, can a ship full of iron float on water?" Locke asked a question that modern people would find very ignorant, and most people in this world would ask the same question as he did.

The difference lies in their understanding of the concept of buoyancy, which modern people have learned, even if they haven't learned, they have seen it, while people here don't know the concept of buoyancy, let alone anyone has ever seen it, and no one has studied it.

"Yes!"

"Why? Doesn't iron sink immediately when it is put in water?" Locke could not understand, so he asked the question on behalf of everyone.

"Iron itself can't float on water, but it can float on it by making it into a boat. I'm here to ask you one thing, one

If you are empty, if you are carrying cargo, the weight of the cargo plus the ship itself, will it not be the weight of the ship?" Ling Feng picked the simplest facts to make them understand.

"Yes!" everyone knows, because shipping things by boat is the most basic mode of transportation, and every day there are ships coming in and out of Blackstone Mountain, carrying away the finished things and bringing the raw materials purchased from other places.

Lin Fanyun even knew that with a ship of the same volume, a wooden boat could definitely transport several times or even dozens of times the materials required by an iron ship of the same volume.

This shows that a boat made of iron can definitely float on water, and this is the principle of buoyancy. Ling Feng said.

"What is buoyancy?" asked Locke, puzzled.

"You want to know, don't you?" Ling Feng asked.

"Hmm!"

"You want to know too, right?" Ling Feng asked Xue Rou, Lin Fan Yundao.

"Yes, yes, you can say it quickly, my eldest young master. Xue Rou said angrily.

"Then go read a book. Ling Feng threw out a sentence that left the others speechless.

“......”

Ling Feng knew that they didn't understand, so he added, "In the textbook I gave to Blackstone Academy, there is an introduction to this buoyancy principle. You guys, don't think that you all think that you are already the leader of the industry, so you don't want to learn new things, you must know that there is no end to learning, and people live to old age and learn in this life. Also, don't think that what I teach my students is elementary and you know, on the contrary, many of them are things that you have never seen and don't know. ”

Ling Feng paused and continued, "It will be beneficial for you to go to the library to read more books in the future. Otherwise, when those students of Blackstone Academy come out, you will know what it means to not be able to keep up with the times. It's not that you have to dig into everything, but at least you need to know something about your major. ”

The library that Ling Feng mentioned above was not the library of the Royal Academy, but the Blackstone Library built in the Blackstone Mountain, and the books in it were provided by the Blackstone Publishing House. And this library is developed externally, anyone can go to read books inside, and you can also borrow a certain number of books to take them out.

But now the people who go to the library to read books are all people from Blackstone Mountain, because outsiders can't get in, so how can they go to the library inside.

"Got it. Lin Fanyun and Locke nodded.

Ling Feng looked at Xue Rou and said, "You too! If you can, you can help manage it just like you did when you were in the Second Town of Blackstone." However, it depends on whether you like this or not, and I won't force it. ”

The reason why Ling Feng wants Xue Rou to manage is first of all because of Xue Rou's ability, if Tianxiang can inherit the throne by a woman, she is definitely one of the contenders for the current succession to the throne (due to the abolition of the crown prince, several other princes are competing for the right to inherit the throne. And it's the one with the best chance of winning.

But that's fine, at least I don't have to worry about her being plotted against her, and her life is in danger because of the inheritance.

There is another reason, that is, I don't want Xue Rou to rely too much on herself and become a strong existence, in case something happens to herself, at least she can take care of Xue Qing, Xue Fei. Although in terms of strength, Xue Qing and Xue Fei can definitely protect themselves, and even protect others, but sometimes their personal strength can't play a role, especially in front of a powerful force.

To deal with a powerful force, you have to use a force that is stronger than him, and there are not many people in Blackstone Mountain's current power that can compete with it, unless it is an empire-level force.

"Got it, young master. Cheryl had a teachable expression.

"Don't dare to be! Let the princess work for the villain, it has already flattered the villain, Her Royal Highness Princess Xie. Ling Feng saluted Xue Rou with a frightened expression.

"Hmph, you know how to bully me!" After Xue Rou grabbed Ling Feng's arm, she began her familiar action - twisting!

"Where did I bully you, where did I dare to bully the princess, I am not afraid of being punished by the emperor. Ling Feng had an innocent expression.

"And say!" Xue Rou glared, then turned into a melancholy expression, and said quietly: "I really want to work for you for the rest of my life, call you young master, I would rather have this than the identity of a princess." I just don't know when it's going to be......"

Ling Feng was silent for a while, and said lightly, "As long as you want, you can do anything." ”

"Then it's decided, I will be your housekeeper in the future, and you are my eldest young master. Xue Rou's face immediately became sunny, and she said with a grin.

Ling Feng smiled slightly and said, "Then it depends on your ability." ”

"That's not trivial. Xue Rou said unexpectedly, but she secretly decided in her heart that she would go to the library more in the future and learn more things, so as to manage Ling Feng's endless new things in Black Stone Mountain, and become a qualified "housekeeper wife".

......

"Ling Feng, the person brought it. Fang Tianya came to Ling Feng with a girl.

How could it be her? The person who came was not Lin Yubing as Ling Feng thought, but ......
