Since that night of solitude, Liu Yu and Liang Yu's relationship has become much closer. Liu Yu also took out the knowledge he had learned to share with her, and the two often studied, discussed, and studied together. From time to time, there was a dispute over a certain disagreement, and in the process of the dispute, the feelings for each other deepened.

In this kind of life and study, the words passed quickly, and in the blink of an eye, Liu Yu entered the Bokan Military Academy to study for a year. After the year-end assessment results came out, Liu Yu could finally breathe a sigh of relief. The grades are not bad, above average, and I can stay and continue my studies next year. After the exam, the students will have to go home for the holidays, Liu Yu has no home to go back, and he has already planned the end of this vacation.

Liang Yu graduated with honors from Bokan College of Engineering and will remain in the school for the next academic year. Many of her graduates will go on to teach.

There are several new professional colleges in Bokan City, and there is a severe shortage of teachers, so these professionally trained students can only be used as teachers to speed up the training of professionals.

By the next year, Bokan City will have five professional colleges: the School of Shipbuilding, the College of Locomotive Industry, the College of Road and Bridge Construction, the College of Metallurgical Industry and the College of Engineering of Bokan. On the basis of these five colleges, five corresponding scientific research institutes have been set up to engage in research work. And the relatively confidential and dangerous gunpowder will be studied by the Bokan Equipment Group itself.

The establishment of the new academies, Guan Xing and Liang Shan, boldly hired young people, and after obtaining the consent of Emperor Liu Xiang, these five academies were respectively led by Liang Yu, Duan Ye, Zheng Zhi, Huang Ruhai and Xu Hui. Xu Hui's family has been engaged in shipbuilding for generations, and he has written a number of papers on ships during his studies at Bokan Engineering College, and has made outstanding contributions to the transformation of ships with steam engines, which has won the respect of Liangshan, so he was appointed as the dean of the School of Shipbuilding.

Huang Ruhai was born poor but diligent, studious, good at innovation, and has keen insight, and put forward very constructive opinions in the development of steam locomotives. The steam engine and locomotive are well integrated, so that the power system can run at full load according to the design requirements to achieve maximum efficiency.

Steam locomotive is a completely new discipline, so it is in need of a young man with an innovative spirit like Huang Ruhai, so Huang Ruhai was appointed as the dean of the Locomotive Industry College.

Now Zheng Zhi is very busy, on the one hand, he is busy with the preparation of the road and bridge construction college, and on the other hand, he is busy with the topographic survey before the construction of the first railway. The trial production of the railroad tracks successfully solved the problem of steam locomotive road travel, and now Zheng Zhi had to build a railway from Bokan City to Fancheng Fortress through Tuha City, the capital of Tuman Province.

As the first railroad built by the Empire, the difficulty of the railway can be imagined, and the places along the railway had to be surveyed one by one and carefully calculated to determine whether it could withstand the load of a steam locomotive. The final construction plan was determined based on the calculation and demonstration of the room full of drawings and every survey data in Zheng Zhi's office.

During the construction of the railway, dozens of bridges, large and small, were built, and several tunnels through the mountains were dug. It has accumulated a lot of valuable experience for the construction of other railways in the future.

Liang Yu will succeed Liang Shan as the dean of the Bokan School of Engineering, while Duan Ye will also use his expertise as the dean of the School of Metallurgical Industry.

In addition to the five major professional colleges, a short-term training center has been set up to train a number of single-caste, low-technical positions. It also enables ordinary craftsmen to get the opportunity to learn and improve their skills.

Liu Yu was not idle after the holiday, and used a few days to sort out the knowledge he had learned as needed, and compiled it into a book according to different disciplines. Not only some advanced industrial technology theories, but also some of the most basic natural sciences have been elaborated in detail for use in various colleges as teaching materials. And popularize some basic surname knowledge in the empire to improve the national cultural quality of the whole empire.
