A few war horses with broken hearts and gall were lying on the ground and twitching, after the excitement of the explosion of gunpowder, these people had to walk back to Chang'an, Yanglin only hated not to bring Wang Erniu, how can I walk this dozens of miles!

Along the way, a few people talked a lot, all about gunpowder, everyone has an understanding of gunpowder in terms of power, but they are still idiots in the application, Yanglin sold a pass here for everyone, the long barrel of the craftsman has been cast some, the principle of this thing is very simple, a high-quality student like Yanglin only needs a small design to increase the power of the earth cannon a lot, and he can make shotguns and flowering bullets, but due to the relationship between time and need, the simpler shotgun is more suitable for the current Datang, Just wait for Gu Yue Daowen to fill the gunpowder and steel balls into the barrel of the large-caliber shotgun, the first firearms used in the military are considered to have been produced in Datang, and Yanglin intends to install them on waterships that are easier to move, as long as the waterships can be dragged in the waterways around Chang'an, even if the army of Jieli Khan is pressed, Datang will have the power to fight.

"Xiao Linzi, you said that if all my troops were equipped with such powerful gunpowder, would there still be enemies in this world?" Li Er's heart was very unsettled, and the impact of suddenly mastering the big killing weapon on the ancients was undoubtedly the same as winning a billion jackpot in later generations, with this thing, you can take anything you want through guò force, and others have no room to resist.

"Father, I'm afraid it's not your enemy that you should worry about at that time, but your own safety, gunpowder is destined to not be widely used, just imagine, when your generals can blow up Chang'an City at any time, can you still be the emperor safely? Invincible has never been a warmonger with absolute force, but a benevolent person who seeks the well-being of the people of the world, gunpowder is not the most powerful weapon in the world, at least I know that there are many more powerful than **, they can even destroy the whole world, but at present, it seems that as long as you have a small amount of gunpowder, you can absolutely dominate the Tang Dynasty, with such an ability, you should think more about the well-being of the people of the Tang Dynasty, when people have no rebellion, no war, Those horrible things will not be born. ”

Everyone has a devil in their hearts, Yang Lin is always afraid that Li Er will release the devil in his heart, while he gives Li Er absolute power, he also has to give him some warnings, gunpowder is not invincible, if you can't be benevolent to the world, there will be something more terrifying than gunpowder to destroy him.

The palace lights at midnight are still bright, and Yanglin can always push out something to help him solve problems when Li Er needs it most, as if he had already predicted that these things were about to happen, Jieli Khan came, and took his 100,000 iron horsemen to break through the Yumen Pass and kill Guanzhong, fortunately, Yanglin's plan to open the canal was implemented, and most of the people in Guanzhong were concentrated in Chang'an City, otherwise, under the disaster and the raiding of the Turks, there were very few people who could survive.

Jieli Khan's advance speed is very fast, the vanguard general Ashina Tusu's army is less than five hundred miles away from Weishui, with the speed of the Turkic cavalry, it can reach the construction site of the river opening at the forefront of Weishui within three days, Fang Xuanling and Du Ruhui and other ministers urgently knocked on the palace door, anxiously waiting for the emperor to appear on the Taiji Palace, the Turkic march speed is too fast, only about three days later than the post horse that transmits the message, and the Tang Dynasty, there are almost no troops that can reach Chang'an City in three days, Several ministers who learned of the military report hurried to the palace when they found that the emperor was not in the palace, and the eldest grandson empress, who never participated in political affairs, also rushed to the Taiji Hall after learning about the situation.

When the waiter on duty at night was about to be interrupted, Li Er finally led a few little guys back to the palace, forming a strong contrast with the expressions on the faces of the ministers, Li Er's mood was extremely good, until Du Ruhui, the secretary of the military department, reported to him the grim shape that the Tang Dynasty was now facing, his face sank, and after thinking alone for a long time and couldn't think of a good way, he turned his eyes to Yanglin who was picking up blood blisters on the soles of his feet, if there was any way to solve the dilemma at present, Li Er could only think of the gunpowder that he had just seen the power of.

"As long as Your Majesty orders the craftsman to set up the place where the water steamer is modified in Weishui, the Turkic cavalry may not be able to come to Chang'an, and we still have three days to change the ship and transport the cannons, which should be enough." Yang Lin looks like he is not in good spirits, with a barrel made of steel with titanium content, he doesn't worry about any explosion at all, and the craftsman can continue to cast a lot of shotguns, as for the bullets of the shotgun, in addition to using steel balls, you can also use pebbles and gravel by the Weishui River, all of them, gunpowder! Li Ke has made a lot of them, the raw materials are not difficult to find, three days is enough for Li Er's die-hard servants to make a lot of them, only Yanglin or Li Ke needs to make a quantitative package according to the proportion, there are cavalry nemesis shotguns, especially the position of the shotguns is still on the Weishui River, Yanglin does not believe that the Turks can cross the Weishui, and another Turkic problem that the Turks may not think of is that there is no snow in Guanzhong this year, don't expect Weishui to freeze.

"It's as simple as that?"

"It's as simple as that."

Yang Lin and Li Er's Q&A made the civil and military ministers in the palace puzzled, under Li Er's compulsory order, the civil and military ministers all retreated, and early tomorrow morning, the Manchu civil and military forces all gathered on the bank of the Weishui River, how to resist the Turkic army, and tomorrow in Weishui to start a military discussion.

The water steamer was originally prepared to start refitting tomorrow, but it was changed from the original Bashui water military camp to the Weishui water military camp, these two rivers are garrisoned by the navy, and there are many ships that can carry more than 100 people, Yanglin gave Gu Yue Daowen the construction of the Wuya warship, which is to abandon the original Tang Dynasty's main battle naval warship Wuya big ship, and directly modify the transport ship with a relatively simple structure, the transport ship has a large draft, high load, simple structure, and wide deck, just enough to install two rows of 20 cm caliber shotguns designed by Yanglin, In the case that the raw materials for the modification have already been prepared, Yanglin believes that the modification can be completed in one day.

Chang'an City in the early morning is very lively, there are a lot of carriages and horses out of the city, Yanglin and a group of chamberlains are pressing a few tightly wrapped carriages, now Yanglin is rarely fully armed, generally when encountering this posture, it is to start the rhythm of fighting, Wang Erniu is interested in carrying a special double-barreled shotgun, this is the magic weapon of the little fairy, he does not let anyone touch, he appeared in the marching team, and no one paid attention to it, Li Ke vigilantly watched everyone who dared to approach these cars, Even the prince and princess had to get his consent, and the convoy slowly marched towards Weishui, there was still more than half a day's way from Chang'an City to Weishuishui military camp, and Yang Lin leaned on the carriage thinking about something.

"Apprentice, you said, if the artifact made by my craftsman overseer defeats 100,000 Turkic cavalry, will it make the artisan superintendent a more important yamen than the three provinces and six departments in one fell swoop?" Gu Yue Daowen looked a little proud, and his spirit was very full, and he was waiting to see his performance in such a big battle of the Manchu Dynasty's civil and military affairs!

"Yes, yes. But it's just in my heart, as soon as the ship and the shotgun come out, the emperor is afraid that he will hide you even more tightly. Yang Lin's words were like a hole in the balloon full of gas in Gu Yue Daowen, which instantly made his momentum leak, he was right, a person who mastered such a murderous aura, even if Li Er didn't want to, he had to watch it tightly, he probably didn't even have a chance to get out of Chang'an City in his life, just like Yang Lin has always been followed by a spring peach who can hear him at any time.

"Let's enjoy this trip to Weishui! Only when these forces that dare to challenge Datang are all gone, can we have a few days of freedom. "Gu Yue Daowen is not a person who likes to drill the horns of the bull, he maintains a proper discordant relationship with Li Er in public, in order to give people an image that he is not easy to get along with, and make people feel that he is a person who is not easy to control, so as to secretly dig out some people with ulterior motives, of course, as the days go by, this trick is no longer very good.

"The assembly of the steel ball bearings of the hydroship needs to be completed by you personally, and the propulsion device of the entire system is assigned to different people to do, at least, before the Tang Dynasty has produced the steel armored ship I said, the fewer people who know about this power plant, the better, especially the Japanese and Koreans, they are very interested in the hydroship, and the envoys of the Tang Dynasty have spent a lot of money to mix into the team of this trip, Mr. should pay attention to the secrecy." Yang Lin admires the ability of Gu Yue Daowen in other aspects, and his hands-on ability is simply the most powerful one that Yang Lin has ever seen, including the most powerful one among the people in later generations, but he does not dare to compliment his habit of taking advantage of his mouth, in case he is provoked by a few words, it is not good to reveal any key points, so he once again reminded seriously.

"Rest assured, I have tried the assembly process of the bearings many times, as long as I am present alone, the central power system is completed by a few old people supervised by craftsmen, until the assembly is completed, and not a single sergeant or minister will be on board." Gu Yue Daowen knew what the meaning of a cross-era thing was to the Tang Dynasty, and how much of a leap would a ship that could move freely without the monsoon bring to the combat power and transportation capacity of the Datang Navy Gu Yue Daowen knew better than Yang Lin, and he had already put a lot of effort into secrecy.
