Otherworldly Castle Era

　　 When Zhang Sun Sheng was on the northern cold island-Arnal Germany, at the moment of the alliance, Yang Song received the long-lost reminder from the system!

　　 "Ding~!"

　　 "Congratulations to the host country Xia Kingdom and Beiyang Ice Island for establishing an alliance between Arnal and Germany!"

　　 "After testing, Arnal Germany is actually a subject of Xia Guo."

　　 "ding~"

　　"The special island country of Anard's subject country is detected, and the system reward is being generated..."

　　 "ding~"

　　 "Congratulations to the host for obtaining the full set of drawings of the sailing warship!"

　　 Accompanied by a series of system prompts, Yang Song only reacted after the system prompts were completely silent at the end.

　　 He opened the system prompt box and looked at this series of prompts, letting Yang Song know that the fleet that was going north to explore had brought him such a big surprise.

　　 And Yang Song carefully looked at the system prompts, and he obtained a piece of useful information: The system can generate useful rewards based on the object!

　　 is the first time that he has such a humane feature. Although Yang Song had some discoveries and some guesses before, it was the first time that he showed it in such an intuitive way with system prompts.

　　 Yang Song thoughtfully read the system prompts and continued to look at the most important system rewards.

　　 This time the system rewards are all drawings, don’t guess, it must be in the library.

　　 Yang Song hurriedly got up and asked Jin Yiwei to call Shen Kuo, Li Jing, Liu Ji and others to the top of the library-the twelfth floor!

"Your Majesty, are there really new drawings here?" It's not that Shen Kuo doesn't believe in Yang Song, but he doesn't know how many times this twelfth floor has been here. He clears every bookcase and every piece of paper here. Chu.

　　 Yang Song didn't say much. After throwing away the words "just come with the lonely", he took the lead to step into the twelfth floor of the library.

　　 As soon as he walked into the twelfth floor of the library building, Shen Kuo let out a "Huh", looking at the hall where the layout of the furnishings had changed, Shen Kuo rushed up and checked them one by one.

　　 The contents of the rows of bookshelves in the front remained unchanged. When Shen Kuo came to the rows of bookshelves in the back, he suddenly rushed up as if he had discovered a new world.

　　 Shen Kuo looked at the logo on the bookshelf, took out the drawing and looked through it twice, and said, "This is the design and manufacturing drawing of the frigate."

"This is a destroyer, this is a cruiser, and this is a battleship." Shen Kuo looked at the signs on the bookshelf in turn, and suddenly he said: "Hey, fast battleship? Battleship? Super battleship? How many battleships are there? Kind?"

　　 After reading a row, Shen Kuo walked to the back row of bookshelves, looked at the signs on them, and said excitedly: "There is really fire** paper!"

　　 Yang Song heard this, put the "Sail Fast Battleship Design" in his hand back to its original place, and quickly followed.

　　 "There are so many drawings of artillery?" Yang Song looked at the whole row, and he was a little surprised that he didn't need the firework papers with few battleship drawings.

　　Looking carefully in order, it turned out that all of them were the design and manufacturing drawings of naval guns, from the five- and four-level naval guns that Xia Guo already had, to the design and construction drawings of the one to three-level naval guns that Xia Guo did not have.

At this time, Yang Song found out that the system rewards did not indicate a little information, that is, the rewards in the system prompts have the words "full set of drawings", which means that as long as they are on the battleship, they have their design and construction. Drawings!

　　 This kind of invisible reward is very rich, such as the glass on the battleship, the extractor, the rudder structure, the rivet, etc., all have their design and construction drawings, and even the tables, chairs and benches.

　　 On the contrary, Yang Song has no major exceptions to the artillery design and construction drawings. Even the supporting ammunition technology only makes him happy, but there are not many surprises.

　　 Because based on Xia Guo's existing technology, it will be a matter of time before he has these. With these drawings, it only makes Xia Guoshao take a lot of detours and save time.

　　It is reasonable to say that even these things are good enough, but the various rewards of the system have made Yang Song a little used to it. It is not unhappy, but the original sense of surprise is gone.

　　 These things are not completely unpleasant to Yang Song. They are about the manufacturing method of the monocular telescope, which contains a lot of theoretical knowledge about optics.

　　 With this knowledge, Xia Guo can develop a complete set of optical instruments on his own. Even a microscope is no longer a dream.

　　 The significance of the microscope is extraordinary. With the microscope, mankind has since opened the door to the microcosm, which is of great significance to the development of science and the progress of civilization!

　　 Yang Song looked at the twelfth floor of the big change, it's no wonder that he has to make another layout change.

　　 The previous layout was very relaxed, the distance between the bookshelves and the bookshelves was very wide, and they were also placed from various angles according to the light.

　　 Like now, the neatly arranged bookshelves are arranged one after the other, and the distance between the bookshelves and the bookshelves has also become much smaller, only enough for two people to walk shoulder-to-shoulder.

　　 Yang Song roughly calculated and found that the twelfth floor of the library has at least twice as many bookshelves, and this time the system's reward is these extra bookshelves.

"It seems that after Chang Sun Sheng and Li Bao come back, I have to ask them carefully." Yang Song looked at a fleet of fleets docked in a harbor in the far north on the minimap, and it seemed to be moving. Replenish.

　　 Of course, after Yang Song, Chang Sun Sheng and Li Bao came back, the rewards they would have given will definitely be many. With this detection fleet with only five ships, it is possible to take over a subject country in the distant Beiyang without support from the rear, and such an achievement is no one! If this is not rewarded, it is impossible to justify!

"Your Majesty, there are so many useful drawings here!" Shen Kuo's voice interrupted Yang Song who was meditating. Yang Song put down the "First Class Naval Gun Casting Technology", which he had been staring at without turning the page, and looked excited. Shen Kuo.

　　 Yang Songman asked casually: "Have you found anything useful?"

"It's much more useful, not to mention the drawings of these battleships and artillery, just say these." Shen Kuo first pointed to the two rows of bookshelves in the front, and then pointed to the bookshelves in the back, very excited: "There is rivet bridge technology in it. With this, the factory building can be repaired bigger~www.wuxiaspot.com~ Shen Kuo said that he also drew a big circle in front of him with his hand, as if there really is a factory building.

"There is also this, the design parameters of the iron nail. This, the drying and mothproofing of wood. This, the production of waterproof paint. And, there is this, the manufacturing method of flat and curved glass." Shen Kuo illuminates the bookcase logo Pointed to Yang Song again.

　　 Before he could finish speaking, Yang Song interrupted: "Very good, save it, wait for you to check it all, make a report to Gu, and mark some special attention."

　　 Yang Song doesn't understand this. Those who are knowledgeable about science and technology should come. He only needs to know the pros and cons and make the final decision.

　　 After coming out of the library and returning to the monarch's residence, Yang Song understood a little more.

　　 The reason why the system rewards these things is all targeted, and it is aimed at ocean control.

　　According to Yang Song's estimation, this is to use these technologies to create an invincible army to control the entire sea area and prevent the betrayal of the subject countries!

　　Wait for him to really build an invincible sailing warship fleet according to these drawings, is there any place he can't go to in the seas of this world?

　　 Thinking of the future scenery, Yang Song's heart is a little hot, there is an urge to wait!
