The news of Li Kun's hanging made Zhu Youzhen silent for a while.

According to the current development, it is unlikely that he will hang himself. But you don't have to hang yourself in that situation!

Isn't it good to cross the sea south and throw yourself directly into the arms of Daming's father? Isn't it trivial to help you hit Amin?

But people are dead, and there is no point in talking about it anymore.

Korea was a vassal state of the Ming Dynasty, and it was justified in sending troops to help the Li dynasty.

This battle must be fought, and the key is how to fight.

"Li Qing, how do you think you should attack North Korea now?" He summoned Li Banghua, the secretary of the military department, to hear his opinion.

"It is better to be sooner rather than later, at the moment Amin's foothold is not stable, and his foundation among the people is still weak, we can send troops against North Korea under the banner of putting things right."

"I know this, how many troops and horses are appropriate to send at the moment?"

"It should not be too much, North Korea is far away, and it is not easy to make up for it. But it doesn't work if it is less, and the art of war is cloudy: ten will surround it, five will attack it, and multiple it will be divided. Without the city, it will not be able to take it. The minister thought that at least fifty thousand. The North Korean soldiers are not to be worried, and the most important thing to pay attention to is the 10,000 Eight Banner soldiers under the command of Amin. ”

Zhu Youzhen nodded. Fifty thousand is a modest number. Siege warfare is not the same as field warfare, even if your firearms are sharp, the casualties will definitely not be less. He considered how to minimize the casualties of his own soldiers. During the Wanli period, although the aid to Korea and the Japanese war were victorious, it also greatly damaged the vitality of the Ming Dynasty. At present, the domestic situation is very good, and we cannot bury the good situation that we have created with great difficulty. Winning the biggest win at the least cost is the result he wants most.

He sent people to call firearms experts Bi Maokang and Sun Yuanhua.

"Old Bi, do you have any new research results recently?"

"Back to Your Majesty, the minister has been working on the rear-loading musket, but there has been no progress for the time being."

Bi Maokang shook his head and replied.

Zhu Youzhen looked at Sun Yuanhua again.

"What about you?"

"Back to Your Majesty, there is no progress in the minister."

Zhu Youzhen nodded and asked the two to go back temporarily.

Even if the research direction is correct, the research results will not come out in a short time.

He found Song Yingxing again.

"Do you know how to make explosives?"

"I know a thing or two."

"I'm talking about the kind of high explosives."

"Your Majesty is talking about TNT, right?"

"Huh? How do you know? ”

"In the chemistry book given by His Majesty, there are also black powder and white sugar."

I have this in the chemistry book I gave you? Why am I not impressed at all? Even add some sugar to Da Yin Wan knows?

"Can you make TNT?"

"Yes. Toluene can be made by nitrification. The three-stage nitrification process is the fastest and the lowest cost. But there's a catch. ”

"Speak quickly!" Zhu Youzhen is a little anxious, and he has difficulty finding me!

"Toluene is nitrified into MNT in the first stage of nitrification, and MNT is nitrified into DNT in the second stage of nitrification, and the third stage is not to be said."

"Why?"

"I'm afraid of being crabbed."

......

"And what is your problem?"

"I'm afraid the amount made by the minister alone is not enough for His Majesty to use in the war."

"Do you know what I'm going to do?"

"Yes! Your Majesty. ”

"I've sent someone to help you."

"Thank you, Your Majesty."

Seeing that the problem was solved, Zhu Youzhen felt relieved for a while. As long as the mind does not slip, the method is better than the difficulty.

The soldiers of the Beijing camp are in full swing preparing to set out for the expedition. An important figure came.

Or rather, three.

Plum?? and his younger brothers Li Hao, Li ?.

On the day of the fall of Seoul, they quietly left the city under the escort of the guards, all the way to the west, and crossed the sea by boat. Landed from Weihai, and then came to the capital.

For the collapse of this country and the death of the prince of Joseon, Zhu Youzhen naturally wanted to summon him.

"I beg your majesty to make the decision for my father! Be the master of the Korean people! As soon as he met Li Kou, he bitterly stated the sins of Amin and others, and hoped that Zhu Youzhen could make decisions for him.

"The prince doesn't need to worry too much, I have already decided to send troops to Korea, and I will send troops soon. In the middle of the time, he drove away Jiannu and returned a bright and prosperous country to North Korea. I still need the prince to go back to preside over the overall situation! ”

"Thank you, Your Majesty!"

Li Kou was overjoyed when he heard this, especially when he heard that His Majesty had asked him to go back to preside over the overall situation. Didn't he say that he was going to be king?

The three brothers stayed in the capital, and Zhu was taken care of by the inspector and treated each other with courtesy.

After nearly half a month of overall scheduling.

The eighth day of June

50,000 soldiers of the Beijing battalion were ready to go.

This time it was Zhang Weixian's son Zhang Zhiji who led the troops.

For Zhang Zhiji, this is the first time in his life that he has commanded so many soldiers and horses, and his heart can't help but be a little agitated.

Onigiri reads a book

It was still outside the Desheng Gate, and after Zhu Youzhenkang's impassioned speech, they set off.

This time, the Beijing battalion still sent the main force of the three major battalions.

20,000 infantry in five military battalions.

20,000 musketeers of the Shenji Battalion.

10,000 cavalry of three thousand battalions.

With Zhang Zhiji's order, 50,000 soldiers and 10,000 people who escorted grain and grass drove out in a majestic manner.

This trip went all the way to the east, passed Yongping, and went out of Shanhaiguan. Then along the coast of Ningjin, through Gaizhou, Dingliao, arrived at the Yalu River.

The trip was more than 1,500 miles and took more than a month.

July 16

The army finally reached Zhenjiang Fort. Here they planned to cross the Yalu River and attack Uiju.

The 50,000-strong army marched mightily in Liaodong, and Huang Taiji naturally did not know it, at first he thought that the Ming Dynasty had sent troops to fight him again. Later, it was found that judging from their marching path, they were not coming for him, but for Amin.

I'm happy to hear it, and he's willing to hit Amin.

He decided not to send troops for the time being and waited for the opportunity to move. Maybe there will be a sandpiper and a clam to compete with each other, and the fisherman will profit.

It turned out that he was thinking too much, and soon he received the news that Zu Dashou and Mangui's 10,000 cavalry appeared outside Liaoyang City. So angry that he smashed all the bowls, when this is his own back garden!?

He immediately ordered troops to encircle and suppress, but the order Zu Dashou got was only to contain Huang Taiji, and there was no need to attack the city, so naturally there was no need to fight him, and once again swept around with cavalry. was so angry that Huang Taiji jumped to his feet, but he was helpless. had to order the people outside the city to enter the city and defend the Liaoshen defense line.

At this point, the situation on both sides has been completely reversed from the Ming army stubbornly defending Ningjin before its own change to Jiannu stubbornly defending Liaoshen. Jiannu's control of the north of Liaoyang existed in name only.

Huang Taiji knew that Daming sent troops, and Amin, as the person concerned, naturally would not not know.

He immediately found his first strategist, Fan Wencheng.

"Sir, I just got the news that the 50,000 soldiers and horses of the Ming Dynasty will arrive at the Yalu River in a few days. What should we do? ”

Fan Wencheng also muttered a little in his heart, why did he come so soon. The people I sent to the court to ask for the seal brought so much gold, silver and jewelry, and it didn't work at all? Even if it drags on for a year and a half. When did the officials of the Ming Dynasty become so incorruptible?

"Your Majesty, since the Ming Court has sent troops to attack, we naturally can't sit idly by. This time the Ming army is attacking the city, and we are defending the city. As long as we hold on to the city, it will not be easy for the Ming army to capture it. In addition, we can spread rumors in the city that the Ming army will slaughter the city when it enters the city, fan the people in the city to participate in the city defense, and increase our defense strength. And the Ming army came on a long journey, and it was naturally difficult to supply, as long as we dragged it out for a month or two, the Ming army could not attack for a long time, and it would inevitably collapse without a fight! ”

Amin nodded, and what Fan Wencheng said seemed to make sense.

"How many troops will you send to Uiju?"

"5,000 warriors of the Eight Banners, and another 10,000 Korean soldiers. The minister is willing to lead the army in person. Fan Wencheng's face was righteous and awe-inspiring, he was really loyal and courageous,

"Eh~ How can it be done! If Mr. doesn't give advice by Lonely's side, Lonely's heart is really bottomless. When it comes to war, just send someone else. When Amin heard this, he firmly disagreed.

"It's... All things are at the will of the king. Fan Wencheng knelt down and saluted, but a smile appeared on his face.

However, it was said that after Zhang Zhiji led the army to the Yalu River, he immediately ordered to cross the river. Stationed five miles outside the city of Uiju.

The strategic purpose of this time is not only to kill people, but most importantly, to recapture the city occupied by Jiannu and drive away Jiannu. Therefore, it is necessary to fight steadily and gradually encroach.

Zhang Zhiji took out a telescope to observe the situation in Yizhou, and found that the city wall was crowded, and it was clear that he was planning to hold on. Zhang Zhiji fell into deep thought.

He sent soldiers to reconnoiter the situation outside the city of Uiju, and in the early morning of the next day, launched an attack.

He also did not send infantry to attack the city, and directly ordered 500 Italian guns to bombard the city, and the defenders who bombed it were hiding behind the female wall and did not dare to show their heads.

Then he sent a banner of soldiers in armor and quickly touched the city gates.

At the head of the city, the person in charge of guarding the city was a Jiala Ezhen of the Eight Banners, hiding behind the female wall and looking at the fifty infantry wearing armor, and asked the people around him suspiciously.

"These dozens of people touched it, what do you mean?"

"I don't know!"

"What do you see on their backs?"

"I don't know!"
