Fang Xiaoyu didn't know what kind of substance the passivating agent of smokeless gunpowder was, and this problem could only be handed over to Deng Jiaxiang, a chemical expert, to study slowly. In addition, nitric acid can make nitroglycerin, which is a high explosive, but nitroglycerin has a very high sensitivity, and it will explode if you touch it a little, as for how to solidify nitroglycerin and reduce the sensitivity, this problem can only be handed over to Deng Jiaxiang to have a headache, Fang Xiaoyu thought irresponsibly while eating.

Life at sea is more comfortable and more leisurely. Fang Xiaoyu and they were not bored, Tesla and others moved their test equipment to the ship, and after they got better from seasickness, they devoted themselves to their own research, and only very difficult problems would come to consult Fang Xiaoyu.

Liu Junxi came to a training with the Iron Guards, and although the space on the ship was small, they still found a lot of training content, such as ship-grabbing training or practicing aiming, and of course, the daily Bajiquan training. Xu Shouchang, the only one who was idle, was instilled with a lot of knowledge of ironclad ships by Fang Xiaoyu in his spare time, so that he could hide and draw pictures every day like a treasure. In fact, a lot of knowledge about warships is just a concept, a manifestation of creativity and experience.

In terms of warship design, Fang Xiaoyu can be said to be the first person in the world, if the classic ship types and ideas in his mind are drawn into drawings that are enough to bury the Royal Navy Design Institute of the Saar Empire, it is enough to pick out a few things that can be used It is enough for Xu Shouchang to benefit immensely.

As for the busiest person on the ship, Fang Xiaoyu, after several times of using the knowledge in the textbook to subdue several scientists, Fang Xiaoyu felt the importance of the knowledge he learned from school even more. Now that the Eastern Continent is still a slave society, there is no universal education at all, and the importance of textbooks is even more self-evident.

If a nation wants to be strong, it mainly depends on the overall quality of the people, and in the future world, it is absolutely impossible for a country with the vast majority of illiterate people to be strong, so Fang Xiaoyu began to continue the work he came from and continued to compile his own universal education textbooks.

Fang Xiaoyu's so-called compilation textbook completely applied what he had learned back then, and although the education system of the motherland was not perfect at that time, at least it was still very solid in the study of basic science. Even if Fang Xiaoyu's memory is very strong, but the relatively old memory may be blurred, only written down can be kept forever, as long as there is time, Fang Xiaoyu not only has to compile textbooks, he also wants to write down his knowledge of the navy and firearms, and hand it over to the scientists under his command to study.

Fang Xiaoyu has a lot of work to do in the room, but he will not always lock himself in the house like an otaku. Work needs to be adjusted, and when there is time, Fang Xiaoyu likes to tease Elena, and after such a long time of contact, he and Elena are already very familiar with each other.

Fang Xiaoyu often teased her when he had time, and often made Elena red-faced, after such a long period of contact, Fang Xiaoyu's extensive knowledge also made Elena very excited, and for Fang Xiaoyu's harmless secret teasing, Elena let him be light. Although Elena is two or three years older than Fang Xiaoyu, based on the elf's lifespan of two hundred years, Elena's actual age is much younger than Fang Xiaoyu.

Leisurely days always pass quickly, compiling textbooks, teasing beautiful women without anything, and teaching those older students when he has time, Fang Xiaoyu has lived a very comfortable life for more than half a year. Even if the means of transportation in this world are backward, there will eventually be a time to reach their destination, not to mention that they have found the nearest way on their way back.

In January 889 of the Taiyuan calendar, Fang Xiaoyu finally returned to the Lanfang Empire after a long absence. Back at Quanzhou Port, Fang Xiaoyu had not yet found a hotel, but he found several signs with the Lanting Trading Company, in addition to a Lanting money village and a McDonald's fast food restaurant. It seems that the development of East China is really good, and the stores have been opened to Quanzhou Port. Fang Xiaoyu didn't alarm anyone, but hired some carriages, and the group quietly set foot on the road to Lanting Mountain Villa.

That morning, when a soldier of the Guardian Army pushed open the gate of Lanting Villa, he found a large convoy in the distance heading towards him, and he immediately asked his companions to keep an eye on him, and he hurried to report back. When Sun Huaizong, Hua Dongxing and the others came to the gate, Elena had already walked out of the carriage with Fang Xiaoyu.

Sun Huaizong ran over excitedly and said, "Young Master, you're back, I haven't seen you for the past two years, I miss you to death." Fang Xiaoyu smiled: "I miss you too, I have gained a lot when I come back this time." Hua Dongxing stepped forward with a smile and said, "Young master, you have gained a lot from not being with us in the past two years." ”

Fang Xiaoyu nodded and said, "I saw it as soon as I came ashore, I didn't expect that you had already paved the industry of Lanting Villa so big." Hua Dongxing said: "When I have time, I will report to the young master about the development of the past two years." Fang Xiaoyu nodded and said, "Let's talk about it in the evening, I'll introduce you to a few new friends first." After speaking, Fang Xiaoyu introduced everyone to Tesla and other four people who had just gotten out of the car.

Fang Xiaoyu pointed to Tesla and the three of them: "These three are talents from the Western Continent, and they were hired back by me." He pointed at Xu Shouchang again and said: "This and Feng Jing, like them, are also talented people who have gone to the Western Continent to study successfully. Sun Huaizong and the others stepped forward to salute, although Tesla and the others did not understand the etiquette of the Lanfang Empire, they also knew that the other party was giving a salute to themselves, and they also saluted according to the habits of the Western Continent.

Qian Huilin walked out of the crowd, stepped forward and grabbed Xu Shouchang's hand and said, "It turned out to be you, Brother Xu, you are finally back." Xu Shouchang was also surprised: "It's really good that Brother Qian is actually working under the young master." Fang Xiaoyu pointed to the two of them with some confusion: "You two know each other?" Qian Huilin said with a smile: "The two of us were originally classmates, but after graduation, I chose to return to China, while he chose to stay in the Nantes Empire." Huo Lan also stepped forward and hugged the two of them and said, "The three of us are all classmates, I haven't seen my dear Qian for a long time, I really miss you." ”

Looking at the three of them who hugged each other excitedly, Fang Xiaoyu said with a smile: "But today you finally came together again, you two are the only shipbuilding engineers I have here, except for the freak of Horan, of course, my fleet will depend on you in the future." Xu Shouchang smiled: "That's no problem, I'm going to build the kind of giant battleship you said." Holland protested, "How can I say I'm a freak, I just like stealthy boats." Qian Huilin said with a smile: "It's good that our three old classmates have met again, it seems that Huo Lan's research has been appreciated this time." ”

Everyone greeted each other in front of the gate, and Sun Huaizong invited everyone into the villa. Lin Feng has been helping Sun Huaizong manage the villa recently, and when he saw so many new people, he immediately went to arrange a place to stay, and it wasn't until everyone was seated in the living room that he came back sweating profusely.

Seeing Lin Feng coming back, Fang Xiaoyu hurriedly greeted, "Brother Lin Feng, come and sit." Lin Feng wiped his sweat and said: "I just arranged it, the four newcomers will live with Mr. Feng and them, and there is an empty small courtyard next to them, which is more than enough for four people." Fang Xiaoyu nodded and said, "That's great, you can discuss problems together in your spare time." ”

Qian Huilin said: "That's great, Brother Xu and I, Brother Huo Lan haven't seen each other for many years, but we have to be close and close." Feng Jingru asked: "Young Master, I don't know if you still want to go to the Western Continent to study." Listening to Feng Jingru's words, Fang Xiaoyu's eyes lit up: "What? Are there many people who have studied in the Western Continent? ”

Feng Jingru said: "There are not many people, but the Lanfang Empire looks down on these people who study practical science, so they are all relatively down-and-out, as long as the young master wants to find me, he can find them all." Fang Xiaoyu nodded and said, "Of course, there is one to one, even if I want to learn Aberdein, I can translate some books and teach students." ”

Feng Jingru nodded happily and said: "Then I'll contact you, dozens of old classmates have come to me during the time that the young master has left, and I don't dare to call the shots when the young master is not there, just let them wait first." Fang Xiaoyu said: "Hurry up and invite them, we will be treated well." Sun Huaizong on the side said: "Young master, have we used so many people?" It would be good if the young master could become a lord in the future, but now we don't have so many places to settle people. ”

Fang Xiaoyu smiled: "Place? Now my place is big, young master. Seeing everyone's surprised eyes, Fang Xiaoyu continued: "All of you here are close to me, and I will tell you a secret here, but this secret is very important, and it must not be passed on." Everyone nodded and looked at Fang Xiaoyu with curiosity.
