In the military machine hall, looking at the sand table, in fact, the Ming army at this time has already captured a large part of Liaodong.

In the four years of Hongwu in the Ming Dynasty, even set up the Dingliao capital guard in Liaodong, and the soldiers set up Liaoyang Mansion and County in June of the sixth year of Hongwu. The location is in Shenyang in the later generations.

However, the strength of the Mengyuan in Liaodong was strong, and the power of the Ming Dynasty was weak, and after the initial capture, it could not be held at all. In the tenth year of Hongwu, he had no choice but to abolish the administrative yamen of the prefecture and county, and only the guard of the military unit was retained.

The Mengyuan forces, led by Nahachu, have continued to attack over the years and wiped out more than 20,000 Ming troops, mainly because of the casualties of these guards who went out of Liaodong.

Therefore, at this point in time, the guards that the Ming Dynasty extended out on the Liaodong side actually existed in name only. The iron horsemen from Naha can go directly to the coast of Liaodong.

Originally, in history, when the Ming Dynasty accumulated 200,000 troops to attack Nahachu, it was mainly attacked from the direction of the grassland.

Standing on the side of the sand table, Xu Da, who was most familiar with Liao affairs, introduced the real situation one by one.

Regarding this situation, Zhang Yifan was taken aback. In his impression, at the beginning of the founding of the Ming Dynasty, so many generals should be invincible and invincible, why were they pressed and beaten by ***?

Knowing his thoughts, Xu Da was a little speechless, and immediately replied to him: "Today's Guanwai is still *** dominant, and our support is often not timely, and by the time the reinforcements arrive, it has already been captured. Even in some places, it is not easy to reinforce, and it is likely to be surrounded by *** to send reinforcements, and the army that goes out to reinforce will suffer! The morale of the troops outside the gate is unstable, and His Majesty also cut down a commander who escaped before."

Lan Yu on the side heard this, and also said: "After all, they have been in the pass for decades, and they also have experience in attacking the city. Even that counterweight trebuchet can't be stopped by an ordinary city!"

Zhang Yifan listened, his eyes rolled, and he immediately said: "That's not right, let's put on a posture, just here in this Haizhou Guard, we must strengthen our troops, hoard materials, attract *** to attack, and then we can destroy a batch of them, catch a batch, just come like this twice, and we can't kill them!"

After he finished saying this, Xu Da and Lan Yu couldn't help but glance at each other, and their eyes were a little speechless.

In the end, Xu Da replied to Zhang Yifan: "Yifan, your idea is good, but you may not have listened to what I just said. Even if it's Haizhouwei, it's only a hundred and twenty miles away from the coastline, but we get the news that if we set off from Guannei again, or gather people and horses in the Liaodong Corridor, it will be too late."

In order to show his closeness to the big horse, so as not to say that this was too ugly for Zhang Yifan, he also changed his name.

Lan Yu on the side also explained: "Haizhou City is not a big city, there are not many people, unlike Yongping City, it is difficult to cope with the long-lasting siege of ***. In addition, *** will definitely release rangers in the Liaodong Corridor, we can't gather troops from the Liaodong Corridor, we can only take the sea route reinforcement from the Guannai to take it by surprise, but in this way, the time is too long!"

Zhu Di didn't speak, listening to his father-in-law and Lan Yu's explanation, he couldn't help but show some regret.

Zhang Yifan listened, and when he was about to speak, he burped.

Rice wine is generally drunk hot, the taste is good, and the stamina is a bit big. However, Zhang Yifan didn't drink much.

After he finished his drinking and burping, he immediately laughed and said, "No, no, no, you are not right, Haizhou City will definitely be able to defend it, just prepare more firearms." Reinforcements don't have to start from Kannai, so there's no need to wait too long for reinforcements......

Hearing this, Xu Da couldn't help but shake his head, interrupted Zhang Yifan's words, and explained helplessly: "I know that the Bombardment Cannon is very powerful and can hit far away, but once you get used to the Bombardment Cannon, the help for defending the city will not be as great as you think. As long as *** scatters a little during the siege, the bombardment cannon will not cause much damage to ***. It must be a catapult that bombards them, but the cannon is slow to fire."

Seeing that Zhang Yifan wanted to speak, he added, "Although there is still a tiger squat cannon, this shortcoming is also very obvious. The range is very short, at close range only

There is a chance of a cannon, and if *** continues to attack, the role of the tiger squat cannon will be limited. If you rely on 10,000 enemies and explosives to defend the city, the consumption is very high, and you can't hold out for long. We can only send reinforcements from Kannai!"

When Zhang Yifan heard this, he hurriedly shook his hand and said, "No, no, no, you're not right!"

Zhu Di: "......"

Although he really wanted to fight, he was not stunned. After listening, he stood on his father-in-law's side, and immediately said to Zhang Yifan: "Yifan, you have drunk too much and are hot-headed, I will ask someone to get you some sobering soup!"

When Zhang Yifan heard this, he didn't want to leave him, walked a few steps, changed to the side of the sand table, and then pointed to the side of the sand table, and then pointed with his hand and said: "There should be a big island here, as long as you quietly accumulate troops here by sea, once there is a war, support Haizhou Wei by sea, at least half of the distance will be shortened, is it enough?"

What he was referring to was Juehua Island outside Ningyuan City in later generations. This island is definitely big enough, and it was used to hoard grain and grass during the war between the late Ming Dynasty and Jianyu.

As a result, when it froze in winter, the wild boar skin led the *** to attack Juehua Island, burned the grain and grass, and slaughtered the soldiers and civilians on the island, which seriously affected the war in Liaodong.

When Xu Da, Lan Yu and the others heard what he said, they were taken aback.

Then, Xu Da immediately remembered, and hurriedly nodded and said, "Yes, there is indeed an island here, if it is used for hoarding troops......

Speaking of which, he didn't say anything, looking at his expression, he was thinking about this possibility.

Lan Yu didn't know about this island, and Zhu Di didn't know either, so Zhu Di asked Zhang Yifan a little curiously, "Yifan, how do you know that there is an island here that can be used?"

"You won't ask, anyone can know if you ask, such a big island, you can't see it if you're blind, and it's a shame that you're leading the sailor, so you don't go to check the situation along the way."

Zhu Di: "......"

After being speechless for a while, Zhu Di simply admitted immediately: "This point is my neglect, my fault!"

As soon as he finished speaking, Xu Da had already thought about it, and immediately said, "If I'm not mistaken, it's indeed a big island. But if you have to accumulate troops in advance, and if you hide your traces and think that you are a surprise soldier, you can't hoard a large army. At most, 350,000 will reach the top. We'll have to go to the island to see how much."

Speaking of this, he was very serious, looked at Zhang Yifan and said, "Even if there are 50,000, if you support Haizhou Wei, I am afraid that you will not be able to have an advantage in terms of troops. Liaodong's *** military strength is around 200,000!"

There was one thing he didn't elaborate on. It is impossible for Liaodong to come out, so although there are 200,000 troops, but when the time comes, the siege of Haizhou City will probably be about 50,000, if you hear that the Ming side will send reinforcements, you may also increase some troops, reaching about 500,000 to 100,000, and the number of troops must be more.

Zhang Yifan listened, but he didn't care, and immediately replied, "Then we must win." It can't all be elite. If there were 200,000 elites, they would have counterattacked a long time ago. The troops we send are elite, and that's enough."

Speaking of this, he saw that Xu Da wanted to speak again, so he took the first step, and immediately continued: "I am already asking people to renovate the ironworks, and the output of steelmaking will increase in the future, and we can equip our elites with stainless steel cuirasses when we go back, and in addition, we will also build a batch of muskets, which are many times more powerful than the current assault rifles." Not only the range, but also the rate of fire will be improved in an all-round way."

Hearing his words, Xu Da couldn't help but be very surprised. And Lan Yu and Zhu Di were already overjoyed.

Compared with Xu Da, the two of them know Zhang Yifan better. Knowing that he said that, that's definitely a good thing!

But who knows, it's not over yet, so I heard Zhang Yifan continue: "In addition, you can also build a batch of artillery, let's call it rapid-fire cannons, the loading speed is at least three times that of the bombardment cannon, and the range will be much shorter, but it is also farther than the bow and arrow, I mean the effective range......

This rapid-fire cannon is actually something that existed in the Ming Dynasty in the original history, and the original name was the Franc cannon, which originated from the Portuguese.

However, the Franc cannon from the Portuguese and copied by the Ming Dynasty is a molecular mother gun, which is equivalent to a cannon chamber

The kind that comes out alone. A female gun is usually equipped with six or seven child guns, and the child guns will be loaded in advance, and the speed will become very fast.

However, one of the shortcomings of this original historical Franc cannon is that the air tightness is relatively poor, not only is it easy to injure the soldiers who fight the Franc cannon, but the firing range will also be affected and become not far.

However, this shortcoming is actually very easy to solve, as long as it is changed to the embedded filling sub-gun method, the airtightness problem can basically be solved.

At the end of the Ming Dynasty, the entire Ming Dynasty system was rotten, otherwise, with the types and configurations of firearms at that time, it was definitely an enemy that could hang cold weapons.

Hearing his introduction, even the steady Xu Da was pleasantly surprised, and immediately stared at Zhang Yifan and confirmed, "Really? Is there such a powerful artillery?"

For people in this era at the beginning of the Ming Dynasty, Zhang Yifan said this, which is a bit unimaginable!

Although Lan Yu believed that Zhang Yifan would create a miracle, he couldn't help but confirm: "This kind of artillery can also easily follow the army in field battles?"

However, Zhu Di did not ask, because he believed that if his brother-in-law said this, he would definitely be okay.

Zhang Yifan, hearing their words, said as a matter of course, "Is this so hard to imagine? Got the Bombardment Cannon, right? In fact, it is to dig out the chamber at the back, and then use a small number of guns, pre-load, and stuff them into this gap to form a cannon that can be fired, it's as simple as that!"

Xu Da: "......"

Sappy: "......"

Zhu Di: "Hehehe!"

Look, the old man should know how smart Yifan's brain is, right?

Zhang Yifan saw that Xu Da and Lan Yu were staying, so he took a step back and hurriedly declared: "Of course, I said that this needs to be built, it will take time to create it from scratch, and it will probably take several months."

Hearing him speak, Xu Da had already come back to his senses, and immediately smiled all over his face, and hurriedly said, "Don't be in a hurry, it's okay to take your time, if you need something, just open your mouth, Beiping doesn't have it, I'll go and ask Your Majesty for it!"

At this time, Zhu Di interjected and said, "We also have to check your island, and then make plans to deploy this war, how can it take a few months, no hurry!"

When Xu Da heard this, he couldn't help but glance at him: This has already been arranged?

Zhu Di obviously understood what his old father-in-law's eyes meant, and replied helplessly: "If we don't talk about this war and don't fight this battle, do you see if we can force Yifan to come up with this!"

When Xu Da heard this, he thought about it for a while, and had to admit that his son-in-law had a point. This big colt really wants to be interested in him, and he will have some wonderful ideas!

Okay, judging from the results of the current discussion, if what the big horse said can really be done, then the elite division of the Ming Dynasty will not fall behind against many times the ***, and the reduction in troops can also make the logistical pressure lighter, which is also beneficial.

Therefore, in the thirtieth day of the Chinese New Year's Eve, several people agreed on the arrangements for the coming year.

Zhang Yifan pounced on the side of the military industry, and first built more powerful guns, artillery, as well as fish floss and meat floss, he also had to take care of them. All in all, it's a logistics-related piece.

Xu Da mainly built the Great Wall and Shanhaiguan and other places.

Zhu Di and Lan Yu, in the spring of the new year, will take a boat to Juehua Island to inspect the terrain and verify the possibility of amassing troops on the island and launching a premeditated Liaodong war. ………………

On the same day, Mongolia *** was not very happy. Even if they have been in the customs for a long time and have been influenced by the Han people, it should have been a festive day on this important day, but this year, there was no festive atmosphere at all.

Gray Mountain and other places were swept by the Ming army, and the news had spread to Liaodong and to the base camp of Nahachu.

Most of these gathered Liaodong *** escaped from the Guannei, and I heard that Naha had gathered a lot of people here, so they all fled to gather so many people.

This kind of defeated general has actually been killed by the Ming army, and it is difficult to make peace with the Ming without an advantage

Army of war.

Naha out of the descendants of Mu Huali, one of the four major generals of the Genghis Khan era, although he was captured by the Ming army, he insisted that it was impossible to surrender, and was put back by Zhu Yuanzhang and was named the left prime minister of Liaoyang Province by Emperor Yuan Shun, and then added as a lieutenant, Kaiyuan King and other officials.

He knew very well how to transform these rabble, did his best, racked his brains, attacked continuously, and slowly united the hearts of the people and the army through small-scale victories. As a result, I didn't expect that just as I was breathing a sigh of relief, there was such a big defeat!
