"And when will I be able to lead the army to sea?" Li Chengqian put down the peach in his hand, and his face was obviously a little unhappy. It's not that he really takes what Yang Lin said seriously, it's just that from Yang Lin's tone, he feels that Yang Lin obviously doesn't support him to lead the army to the sea.

"As the commander of the first army, you are responsible for the entire army, and the life of every soldier under your command, if you enter Chang'an Academy in September this year, your knowledge should be enough for you to lead the army in the coastal operations within three years, if you want to go to the Wa Guohai, you have to study for at least another three years, and this must be the case that you can successfully achieve excellent results in all disciplines." Yang Lin didn't bother to pay attention to Li Chengqian's displeasure, at present, he did not have a real position in the imperial court, and the next focus was to make Chang'an Academy run normally, or there was another thing to do, which was to personally raise his first child, as for the battle between the Li brothers, he really didn't want to care, as long as the westbound team returned safely next month, even if there was really any conflict at that time, he was sure to stay out of it.

"Six years, how is it possible, the tank car is so difficult to overtake the new weapon, I can't drive it freely in just three months, the hydro ship is not difficult, the steel armor ship is just an iron ship equipped with a steam engine, it will be so difficult? Don't bluff me, this prince is not an ordinary civilian who can't read big words. Li Chengqian was a little unconvinced, but he had already eaten a peach on the branch, and Li Tai, who launched an attack on the second peach, listened to Yanglin's words and breathed a sigh of relief, he was different from Li Chengqian, for scientific and technological products, he unconditionally believed in Yanglin's estimate, because as the deputy head of the art troupe, the time with Yanglin was far greater than Li Chengqian, and he naturally knew more about the actual use of these equipment.

At most, Li Chengqian's level of driving a tank was to run along the main road, adjust the direction and fire indiscriminately. When he really arrived at the rugged and difficult battlefield in the ravines, or when he asked for accurate strikes on the target, he was completely blind, and it was also strange that there had been no war in Datang in recent years, and the three tanks had become just things for Li Er's father and son to drive to the hunting ground for recreation, and there was no chance of actual combat at all. However, Li Tai has a feeling that the combat effectiveness of the tank is definitely not only this, because he has seen Yang Lin easily cross a ravine more than one meter high when driving the tank, and fire the cannon when the muzzle shifts direction, and the shell accurately hits the target, he knows that this requires a strong mental arithmetic ability to calculate the trajectory of the shell, and he thinks that even if he takes a team of ten tanks to fight against a tank in Yanglin, there is no chance of winning. That's the difference between whether it will be used or not.

"Naturally, I didn't treat you as an ordinary person who couldn't read big words, so I saved you five years of primary school, and the courses you have to study are three years of junior high school and three years of high school, in fact, strictly speaking, you have to have a university level to really drive a ship, because as a captain, the knowledge to be involved is too wide, but between the current good ecological environment. There's a high school level that's about the same. The principle of the steam engine is not difficult to say, but it is a science to really control its power. And it's not a knowledge that you can understand alone, you need a group of people under you to understand, so ah, it will be five or six years before this batch of steelclad ships really forms combat effectiveness. ”

Yang Lin only ate one peach and stopped his mouth, no matter how delicious things were, he was tired of eating them every day, and all the parts of the steel-armored giant ship were made by him. He naturally had a good idea of what kind of quality he could achieve, 5,000 tons of drainage, one hundred and eight alloy cannons on the left and right that could be adjusted at 180 degrees, three-barreled cannons with 300-degree corners and nine fixed rocket launchers installed on the deck, in this period. The firepower can be said to be the most violent.

In the case of full of fuel, ammunition and soldiers, the steel-armored ship can sail on the water for more than two months, and it can reach a speed of more than 30 miles against the water, even if it goes to the Japanese island to go around and come back, but in addition to Yanglin, no one can make reasonable use of the space in the ship and effectively allocate shipboard resources, as for some more advanced technical problems such as weather and reef detection, it is difficult for Yanglin to make instruments at present, without those technical equipment, these ships are only the same as water steamers at sea, Unless the blind cat touches a dead mouse, or an enemy dares to take the initiative to touch his tiger's buttocks, it is difficult to make achievements. At present, it is just a grand landscape on the Weishui River.

"No, I can't wait for five or six years, I'm the prince, I'm busy with government affairs, and I don't have the spare time to enter Chang'an Academy to study, isn't there a quick way?" Li Chengqian asked tentatively. But the answer was no, Yang Lin shook his head firmly at him.

No matter what it is, once it is hooked with the machine, there must be an accurate data to control it, the steel-armored ship is like this, the mathematical ability of the Tang people can reach the level of junior high school students in later generations, they are already considered geniuses, and at present, only those old guys of the god and human race are barely useful, if Yang Lin personally is the commander of a ship, he leads several elders of the god and human race, and he can only barely guarantee that he can safely drive it from the Weishui shipyard to the mouth of the sea, after all, this thing is too big, Even if the Yellow River was more abundant in ancient times than in later generations, it would not work.

"Big brother, you can save it! Xiaolinzi comes out here, generally conservative data, it is difficult for anyone to surpass, you really can't wait, you can lead the wooden water steamer, although some of those warships have also been sold, but the equipment of my Datang Navy is still the most advanced, and it can definitely crush them. It's a tank chariot, and my father only allowed me to take one to Taiyuan, and I don't know if I can shake those clan elders. Li Tai looked at Li Chengqian's unhappy look and quipped.

Hearing Li Tai say this, Li Chengqian was a little moved, but when he thought about the vast sea he had seen in Suzhou, he still felt that it was safer to go to sea on a steel-armored ship, and he thought in his heart, others may not be able to drive this steel-armored ship, can't you be able to do it in Yanglin? As long as the time comes, let the father send Yang Lin as the deputy commander, then the steel-armored giant ship will not be able to be used.

"A tank is enough for you to go to Taiyuan to show off, but when you say this, I think that Taiyuan seems to produce coal, and this thing is just used as tank fuel, if Your Majesty intends to use troops against Xue Yantuo, your Taiyuan army must be one of the main forces, with tanks as the forerunner. Those Xue Yantuo's armies who can only use cold weapons have not been crushed by you in the same way. As soon as Yang Lin said this, Li Tai's eyes suddenly lit up, he almost forgot that Taiyuan is a strategic place for troops outside the Guan, as long as the tank has enough fuel, entering the prairie is like a wolf entering a flock, which is the work of expanding the territory. Li Tai is very greedy, maybe Li Er changed Li Tai's title to Taiyuan, which means that as a strategist, his subordinates will always maintain restraint against their neighbors.

Yang Lin did not say that in his basement he had made three new tanks that were much more advanced than the three tanks parked in the palace, which was only his follow-up to Chang'an's changes, and as for the steel-armored warship assembled by Gu Yue Daowen, it was only used by Yang Lin as an experiment for hand training, since he built the pneumatic lathe. It becomes easier to make all the rough mechanical products, the barrels and shells installed by the new tanks are already extremely similar to the second-generation tanks of the later generations, and then they can reach the level of the Second World War era, for Chang'an City, such weapons are already absolutely invincible, and he currently has no plans to make more advanced tanks and warships, his research and development focus has begun to shift to the spaceship, and the seeds of sisal are about to arrive in Chang'an. As long as the raw materials that can be used to make sealing materials are grown in large quantities, it is only a matter of time before the helium spaceship is built. As long as he has exclusive mastery of aerospace technology, then no matter how big the war is in Chang'an City, he is confident that he will absolutely guarantee his safety and play a key role in determining the outcome of the battle.

On the other side of the garden, Li Lizhi introduced some devices that were not available elsewhere in the Horse Mansion to Li Er, in a large open space near the orchard. All sorts of strange things are placed everywhere, and it is clear that it is a construction site that has not yet been completed.

"Father, mother, this is Xiao Linzi's gift to his first child, he said that after it was built. It's called a children's playground, and there are hundreds of devices for children to play with, and I've seen all the drawings, and it's very exquisite! Li Lizhi pointed to this place, which covers an area of several acres.

"Playground? Tianzhu really has a heart, but it seems a bit wasteful to focus on these things. At Li Er's age, he naturally thinks about more national events, he doesn't know the importance of a place to play for a child, the key is that this place is full of Yanglin's love for Li Lizhen and their children, so when he heard Li Er's words, Li Lizhen was reluctant and said: "You didn't give him a position in the court, do you blame him for not caring about national affairs?" ”

"You kid." Li Er and his wife were stunned when they heard this, and Empress Eldest Sun was the first to react and glanced at Li Li, and then turned her head to Li Shimin and said: "The water splashed by the married daughter, our Li family is no exception, but a talent like Xiao Linzi can't be idle, those who know know that he has no intention of going to court, and those who don't know, think that His Majesty is guarding against him!" Some ill-intentioned people! It's going to have bad thoughts. ”

"Bad thoughts? You two! After all, she is still a woman, who doesn't know how capable this kid is, you see that in the past few years, someone has put crooked thoughts on him? I just don't worry about handing over this world to him, the things in his mind have never appeared in this world, and it is too difficult to predict what kind of results can be caused, Chang'an Academy, maybe the last thing I think can be handed over to him to do. ”

In front of his family, Li Shimin doesn't need to hide so much, with the strength of the Tang Dynasty now, he no longer needs those whims of Yanglin, foreign enemies are not enough to trouble, internal stability, and the people are rich, he just wants to maintain the current situation, as an emperor, he understands more that entrepreneurship is easy to keep a business, so now his life focus is in addition to the love in his heart, that is, his sons, Li Ke has been in southern Xinjiang for a few years, and his achievements are not small, in the past few years, he has built the entire southern Xinjiang road, The degree of communication between the aborigines of the large territory in the south and the people of the Central Plains has been further improved, and the infrastructure construction of some small towns where ethnic minorities gather has been gradually completed, so that the people in those new territories have a lot of hearts, but he is always the second echelon candidate in Li Er's mind, because he is from Concubine Yang. And Li Tai and Li Chengqian are uncertain in his heart, first of all, they are both the descendants of the eldest grandson and empress, and they have advantages that all other princes do not have, except for Li Zhi, who has not yet woken up.

Secondly, they had already woken up before Li Er became the emperor, knowing the cruelty of the political struggle, let them be emperors, at least in this generation, there will be no problem with the inheritance of the Li family, and in the end, both of them have the heart to ascend the throne, have the desire for power, and have the desire to control, which are the two points that must be possessed as emperors.
