"I have!" Li Yi replied in the affirmative. "But it will take time."

"How long?"

"A year at most, half a year at a time!" Li Yi kept making calculations in his head. "In fact, not only the people's will, but also supplies, climate, marches, battles and so on have a lot of deficiencies."

Li Er breathed a sigh of relief. "This is natural, you kid don't think I'm going to go east soon, do you? I still don't know how to prepare for war? If I prepare now, I will not be able to set off until the beginning of spring next year at the earliest, which is enough for you to prepare for more than half a year. Li Er shook his head, and immediately looked at Li Yi's gaze changed slightly. But you kid has made a lot of progress, and you actually know so much. ”

"That's right, you don't look at whose grandson I am." Li Yi raised his head proudly.

"Come on, the pharmacist doesn't know how many times he complained, saying that you wasted all your martial arts and shrewd mind, if you really follow and learn skills, my Datang will definitely have another god of war."

"Don't. Li Yi hurriedly waved his hand, Datang already has a military academy, what else does it need, what is the desire of the people, it is the best god of war. I think it's more useful for me to plan and plan. ”

"Well, this kid is right, I have to say that the Military Academy is definitely an unprecedented initiative, boy, with this Military Academy, you are enough to go down in history."

Now Li Er has treated the Military Academy like a baby, and it is really the Military Academy that has given him too many surprises.

After those students who graduated from the military academy entered the army, they not only improved the centripetal force and combat ability of the army, but also condensed the loyalty of the army soldiers, and now Li Er's control over the army is increasing day by day, especially the Sixteen Guards, many of these people have been supplemented by Li Er into the Sixteenth Guard, and the current Sixteen Guards are absolutely completely loyal to Li Er, and now Li Er is very relieved even if he completely persuades the army to let go, because, once those generals want to rebel, they can't command even a single soldier.

"Your Majesty, I don't think it's good to march in the spring."

"Why?"

"First of all, it was rainy in the beginning of spring, and the road on the march must be muddy, which was not conducive to the march, and would greatly slow down the speed of our march, which gave Goguryeo time to react. Goguryeo's army, good at bows and arrows, the most defended city, once they are cowered in the city, then we can only fight city by city, this is not only time-consuming, if Goguryeo once condensed the barbarian army, we are likely to follow in the footsteps of the Sui. ”

"It's inevitable. As for how to win, it is a question of combat, what does it have to do with the time of the march? ”

"Your Majesty, you say, if we can march in winter, will it be a surprise?"

"What? Winter March? It's ridiculous. Li Er laughed. Didn't you kid go to Liaodong? You don't know what winter is like there? Fighting in winter, half of our army can freeze to death before it reaches the place. ”

"Ordinary marching is not possible, but if we have clothing that can not be afraid of the cold, will it be fine?"

"Huh? Clothes that don't fear the cold? What is so magical about clothing? ”

Li Yi shook his head. "It's hard to say for the time being, if Your Majesty feels that after the problem of keeping the soldiers warm, the winter march is promising, I will give it a go."

Li Er also came to the spirit.

"Winter marching, the biggest problem is the problem of cold and warm, if this problem is solved, then the winter march is definitely the best choice, not only to solve the problem of muddy marching roads, but also to do surprise, to hit Goguryeo by surprise, the most important thing is that Goguryeo has no cold clothes in winter, they will lose congenitally, boy, if you can really make cold clothes, this crusade, I have ninety percent certainty."

Li Yi was immediately overjoyed. "Really? It seems that the kid's previous preparations were not in vain. ”

"What are you preparing?"

Li Yi smiled. "Your Majesty, in fact, after returning from Goguryeo four years ago, the kid began to prepare, but he has been in the accumulation stage, and he hasn't had time to experiment yet, once the experiment is successful, the kid is completely sure that he will make 500,000 pieces of warm clothes in half a year."

"200,000 pieces...... Li Er calculated. Goguryeo has been recuperating in recent years, and their army has nearly 400,000 people, and I originally planned to send an army of 600,000 people, but now it is only 200,000......"

Li Er hesitated. However, Li Yi is very confident. "Your Majesty, it's enough, first of all, with the popularization of new military training methods and the efforts of military academy students in recent years, the overall combat capability of the Tang army has risen to a big level, and it is completely possible to defeat one enemy with two, so, even if you count Goguryeo's ability to defend the city, we actually only need 400,000 troops to be enough, and now if we march in winter, they don't have warm clothes, we have more time and place, and 200,000 troops are completely enough, not to mention that we still have wolf warriors, gunpowder and some other secret weapons....."

"Gunpowder? Your Divine Machine Academy's gunpowder has been successfully developed? ”

"Sort of, there are still some small problems left, which can be solved in half a year, and when the time comes, gunpowder alone will be enough to top an army of 100,000."

Li Er frowned, thought seriously for a while, and said slowly: "Boy, I want to ensure that nothing goes wrong, if you really develop cold-resistant clothes, then I want 300,000 pieces, and if you want people and things, you can speak." ”

"Three hundred thousand?" Li Yi opened his mouth and smiled bitterly. "In fact, this is not a problem of manpower and material resources, but a shortage of materials." Li Yi thought for a while, and suddenly said: "However, it's not impossible, kid do his best!" ”

Li Er patted Li Yi on the shoulder and said in a deep voice: "Boy, there is no room for loss in the conquest of Goguryeo, if you can solve all these worries for me, I will definitely be able to win a big victory." ”

"Hehe, this kid never doubted that Goguryeo could be His Majesty's opponent and they relied on, but it was just the right time, place and people. Your Majesty, rest assured, such a big thing, the kid will never be sloppy. ”

Li Er nodded. "I've always been relieved that you're doing things. Boy, I don't like what you promised, what you did for Datang, I will never forget. ”

"Hehe, it's actually very simple, if you return triumphantly, then let the kid go back to Jiangnan, this is the best reward for the kid."

"Hmph, you want to be beautiful, you kid don't want to be lazy in your life!"

"Nani? Your Majesty, you're not serious, are you? ”

"What do you say.....

Li Yi was momentarily stunned.

Li Er laughed on the side.

.......

and Li Er summed up some details, Li Yicai took Changle and Li Le back to the Li Mansion, the current Li Mansion has already been in full swing, the eldest young master has returned, and the Li Mansion has not been so lively for a long time.....
