Li Longji can actually guess that these blank areas are a land of no authority, but he needs Li An’s confirmation to further affirm his point of view.

“Your Majesty, the northernmost and southernmost part of the map is a world of ice and snow. The four seasons of the year are bitter winds. It is difficult for anyone to survive here. It is a Desolate Land, and there are large areas in the rest. The land, some can be called a land of grief, but there are almost no people in these places, only wild beast and all kinds of plants and flowers, only a few places there are some barbarians, because there is no Imperial Court rule, so this Small Official leaves a blank . “

Li An looked towards the map and explained.

Li Longji gently nodded. I have no doubt about what Li An said. After all, Li An has invented too many machines that shocked the world in these days. If Li An did not meet Saint White ’s instructions at White Wolf Mountain, I ’m afraid that no one believes, and since Saint can invent machinery, of course, he should know the size of the world. Moreover, Li An also said that this map was drawn by experts outside the world. So, how could Li Longji not believe it? .

“It turns out that most of the world is a land of no ownership. The Imperial Court ruled only a small part of it, and the sea is so vast, many times larger than all the land!”

Li Longji was shocked by looking towards the map. What struck him was not only the huge landless land outside the Great Tang, but also the more extensive ocean. The huge ocean area was unexpectedly unexpected by him.

“Your Majesty, although the world is big, among all the Imperial Courts, only the land owned by the Great Tang Imperial Court is the most, and it is also the most respectable. My Great Tang is the largest and strongest of Between Heaven and Earth. Empire. “

Li An is confident and proud of being Great Tang Erlang.

Li Longji abandoned the borderless land and the vast ocean, looked towards all the color-coded empire, and suddenly a smile appeared on the corner of his mouth.

“Yes, my Great Tang is indeed the Imperial Court with the largest land, followed by Tibet, Aab Caliphate, and Turks. The west is a barbaric country, not enough.”

Seeing that the land of the Great Tang empire is first and second only to the great powers of the Great Tang empire, they are all around the Great Tang empire and suppressed by the Great Tang empire. Li Longji’s mood has become much better.

“Your Majesty, This Small Official has always had a good memory. I still remember that Grandpa once said that there are a lot of rare good things in the distant land. There are 1000 pounds of sweet potatoes per mu, 500 jin of corn per mu, and There are a lot of edible things, many big trees are not in the Great Tang here. In the future, when the railway is repaired to Laizhou, must build a steam sea boat, go to these places to explore, and bring back a lot of good things that are needed. “

Li An is looking forward to the future and making demands.

“Sweet potatoes with a yield of 1000 pounds per acre, Minister Li, are you sure you have heard correctly?”

Li Longji was shocked when he heard that there were 1000 pounds of sweet potatoes per mu. This yield was several times higher than the highest-yield crop available at Great Tang. If the sweet potatoes were shipped to Great Tang, they were planted in In the land, the food production of Great Tang will multiply, and the famine will never be missed by the Great Tang Empire.

“Your Majesty, how could this Small Official get it wrong? It is indeed 1000 jin per mu, and almost no fertilization is required. It can grow very well on very poor land. Almost all of the Great Tang can grow. It ’s just that the more fertile the land, the higher the yield per mu. “

Li An explained with a smile.

“1000 kg per mu. If there is such a crop, I will never have the problem of famine in Great Tang. Must dispatch Fleet to bring the sweet potato seeds back to Great Tang.”

Li Longji certainly would not give up such a high-yielding crop, and made a decision immediately.

“Your Majesty, America is also 2 ten thousand li closest to the Great Tang. Ordinary sea boats are too slow. Once the wind direction is problematic, they may not be able to come back. Moreover, the paddle speed is generally slow, which is not conducive to avoiding. The sudden thunderstorms and windy weather encountered on the surface of the sea are still more reliable for steam seaboats. Moreover, This Small Official intends to design a larger nautical steamboat that is more suitable for traveling on the ocean. “

Li An advised Li Longji not to be too anxious, but to eat the food bit by bit, not too impatiently.

“Minister Li, a crop of 1000 kg per mu is extremely important to me. You must research and develop the steamship as soon as possible, and bring this thing back to Great Tang earlier.”

Li Longji seemed quite urgent.

Li An nodded and said: “Your Majesty rest assured that This Small Official is already doing preliminary preparations. All kinds of new steam engines and propeller technology are in Research & Development. The railway to Laizhou will be repaired. Otherwise, many mechanical parts built in Beijing cannot be shipped to Laizhou in a short period of time, and shipbuilding will be difficult. Especially for many huge mechanical parts, only train transportation is the most important. reliable.”

“Railway? Hasn’t Luoyang’s railway to Laizhou been confirmed? It will be laid now and will be repaired within a year. What does Minister Li think?”

Li Longji is still in a hurry.

“Your Majesty, the railway to Zhongshoujiang and Yu Sect is still being laid, the Canal Bridge and the Bishui Bridge are also under construction, and there are also various machinery production, Research & Development requirements, and pig iron In short supply, human and financial resources are difficult to support the construction of this railway in a short period of time. Moreover, there are dozens of bridges along the way that need to be built.

Li An explained carefully and told Li Longji why he could not build the railway to Laizhou immediately because all aspects are not mature. The large steam engines and propellers required for large sea ships are only in the development stage, so there is no need to rush.

“Well, since that’s the case, let’s lay it after spring ploughing next year!”

Li Longji didn’t force it, and he followed Li An’s suggestion. However, it can be seen that this old man was very excited, especially when he saw the blockbuster land.

“By the way, Minister Li, is there only such a big world? Is there no land outside these two sides of the ocean?”

Li Longji looked at the flat World map, curiously asked.

“Uh, this … This Small Official is not quite clear, maybe!”

Li An did not dare to tell the truth at the moment. When the advanced steam ship of Great Tang detours around Earth in the future, the answer will naturally be revealed. It is not yet the time to propose this science.

“Okay, this map will be hung in the Zichen Hall in the future, please leave it first!”

Li Longji asked Li An to step back and stand alone in front of the map, contemplating and conceiving. Such a vast ocean and so many untouched lands make this emperor who has reached his twilight years full of ideas for expanding the territory. Of course, even without this map, he will also have this idea. The objective evaluation of him by later generations.

“Minister Li, what you just said in front of Your Majesty, is the truth? Is there really 1000 kg of grain per mu?”

After stepping out of Zichen Hall, Chen Xuanli looked towards Li An and asked seriously.

“Of course it is true. Do I dare to bully the king? You will see 1000 kilograms of grain per mu in a few years. Wait!”

Li An smiled easily and strode forward.

“1000 mu per mu? Can it be true, my goodness!”

Chen Xuanli mouth opened wide, motionless froze in place.

After leaving Daming Palace, Li An not at all returned to the other courtyard and went to the Research & Development Center. Now, there are at least dozens of products in Research & Development and upgrades.

All Li An needs to do is to provide maps and technical guidance, grasp the general direction, and prevent these Research & Development personnel from going astray. Specific work can be done by the craftsmen.

Among these dozens of Research & Development and improvement projects, half of them are machine tools. After all, only the steam machine tool business has developed, and with more advanced and reliable precision machines can we produce more reliable products, especially It is a lot of precise and advanced mechanical products, which can only be processed with good machine tools.

In addition, in order to build advanced steam sea ships in the future, more advanced and larger steam engines are in Research & Development, and the propellers that drive ships are also in Research & Development.

The method of adding propellers at the stern can greatly improve the efficiency of propulsion, allowing the ship to reach a faster speed, even faster than the train.

Breech Cannon’s casting is also continuing. After some trials, Breech Cannon’s Research & Development has entered the final sprint stage. It is very likely that the final cast of a gun will become a qualified final shaped product.

“How about, Breech Cannon has failed several times.”

Li An looked towards the technical talent responsible for Research & Development Breech Cannon, asked with concern.

“Back to Minister Li, I have failed 3 times. We have also figured out the reason for the failure. This time will surely be a success.”

These best talents, after such a long period of study and Research & Development, have already possessed certain independent thinking ability, and even can judge how high the success rate of the product test is, which greatly exceeds Li An’s expectations.

“Okay, very good. Breech Cannon is much more advanced than the previously cast artillery. It can fire more shells in a short time. Must Research & Development comes out as soon as possible.”

Li An nodded, and took out a drawing from his arms, ordered: “According to this drawing, to build the gun mount of the artillery, this mount is very important, it is necessary to research and development as soon as possible.”

The craftsman took the drawing and frowned: “Minister Li, this gun mount looks too thin, the artillery retreat distance will be larger, is it really feasible?”

“It won’t take a step back, as long as this gun mount Research & Development comes out, the gun barrel of the artillery is mounted on it. When the artillery fires, it will not take a step back.”

Li An said seriously.

This very advanced artillery reset system is the standard configuration for later artillery, and it can also be called a recoil device, which will greatly enhance the formidable power of the artillery and allow the artillery to be used in more places, such as trains and sea ships , Or even inside the vehicle.

“Yes, Minister Li, this thing doesn’t look difficult to make, it will be made soon.”

It is much easier to manufacture the anti-reclining device of the artillery than it is to cast the barrel. After casting the main body, you only need to add a thick spring to complete. This is certainly not much difficulty for the craftsmen of the Research & Development barrel.

Li An is looking forward to it, and looks forward to the advanced Breech Cannon and the anti-recumbent gun mount being released by Research & Development, so Artillery’s battle strength will increase by a large level.

After continuing to inspect several Research & Development projects, Li An left the Research & Development Center and returned to the other courtyard, and copied the World Map with Yan Ruyu 3 people. Of course, this World-level map will need to be made a few more copies. In the future, Steam Sea When the boat goes out for an adventure, you need to bring this map. In addition, Li An also named many important islands on the ocean, such as Guandao, Weidao, Zhongdao, Xiadao, and in addition, these several important islands All the shapes and terrains are drawn on additional maps to allow steam ships going out to sea to understand where they are when they encounter these islands, and to position themselves in conjunction with the World map to prevent getting lost.

A few days later, there was great news from the Research & Development Center. Breech Cannon officially succeeded in formal Research & Development, and conducted 3 test firings. The shooting was stable and accurate, and the earth wall 500 steps away was successfully smashed.

Immediately afterwards, a gun mount equipped with a spring recoil device was also built, and Li An was immediately notified to let Li An guide.

“Minister Li, Breech Cannon has been tested successfully, you said the gun mount has also been built, is it right to try it?”

Li An nodded and said: “Put the gun barrel, gun mount and running wheel all together, pull it out to try the effect.”

Dozens of craftsmen worked together to assemble the barrel, gun mount and gun wheel together to form a perfect looking gun.

The Research & Development Center has a site dedicated to testing artillery, and several concrete walls up to two zhangs have been purposely built.

Looking at this advanced artillery similar to the shape of the Second World War II, Li An was very proud. Although only the appearance is more similar, the formidable power of the shells is much worse, but this is good. In this era, such artillery is enough. It has caused huge losses to potential enemies.

“Aim immediately and prepare to fire.”

Li An gave the order for the experiment.

In addition to the spring recoil device, this new artillery has a handwheel mechanism for adjusting the angle of the artillery. By rotating the handwheel, the artillery can be easily adjusted to the desired angle.

Several craftsmen turned the handwheel, aimed the muzzle at the earth wall 500 steps away, and loaded the cannonball and propellant into the barrel, closing the breech and locking it.

“fire.”

Li An ordered immediately.

“boom……”

The craftsman pulled the traction rope hard, causing the firing pin at the rear of Breech Cannon to quickly hit the propellant, and ignited the propellant to propel the shell towards the target in front.

“Hit, hit.”

“Hey, the artillery really didn’t back off.”

Everyone not only saw the artillery accurately hit the target, but also saw that the artillery only moved a bit, not at all, moving backwards very exaggeratedly.

“Clear the cannon and reload the bomb to continue firing.”

Li An continued to issue orders to fire shells.

Several artisans immediately opened the breech, and after a little cleaning, they loaded the shells and propellant again, closed the barrel, and fired the next shell at the target area.
