Zhu Youxiao can wait for the next year to fight again, Nurhachi can't wait to fight again next year, losing the city of Hetuala, he has to seize another foothold, Pyongyang is his goal, he has now organized an army of 50,000 people, of which 10,000 have been quietly transported by Fan Wencheng across the Yalu River. It is very simple for the Jurchens to organize an army, and any young and middle-aged people are all from hunting, and they can fight with a sword, gun, and gun, and it is very fast to organize another 30,000 people immediately.

Goguryeo has now become a fragrant glutton, the Ming Dynasty thinks about it, the Jurchens think about it, and the Japanese people who have crossed the coast also think about it, just when Nurhachi is preparing, the Japanese people have already started, and the intelligence leader of the Japanese country, Yanagi Zongju, has already received the news that the Goguryeo king Li Hui was deposed, as the teacher of Tokugawa Hidetada, he is always thinking about how to make the Tokugawa family get more benefits, as the intelligence chief, he always pays attention to the information of North Korea. When Toyotomi Hideyoshi attacked Goguryeo, the Tokugawa family did not participate in the war because they could not get any benefits in the east, and now the Tokugawa family has obtained the right to rule the Wa Kingdom, and if they can gain benefits while the Goguryeo Palace changes, they can still consider attacking Korea.

Originally, Tokugawa Hidetada inherited his father's ambition and was reluctant to wage war with the Japanese as the principle of strengthening the rule of the Japanese kingdom itself, but he could not help but be bewitched by the militants. Although the four heavenly kings of the Tokugawa shogunate were gone, their sons were still there, and the three sons of the four heavenly kings, Honda Tadamasa, Kamihara Yasumori, and Sakai Ieji, strongly encouraged Tokugawa Hidetada to start the Goguryeo War, and their reason was to save the Goguryeo king Li Hui, who was recognized by the Japanese kingdom, and help Goguryeo restore normal order. Although this reason is ridiculous, it can also fool some Goguryeo people, after all, Li Hui is still the orthodox successor personally appointed by the previous generation of Goguryeo kings.

As a result, the Wa Kingdom also began to actively prepare for war after receiving the Ming Dynasty's reprimand of the Goguryeo envoys. In the last Goguryeo War, Toyotomi Hideyoshi dispatched hundreds of warships, but lost in the joint operation of the Ming Dynasty and the Goguryeo naval army.

At the beginning of September in the third year of the Apocalypse, on the side of the Wa Kingdom in the Tsushima Strait, nearly 1,000 warships of the Wa Kingdom marched towards Goguryeo, and arrived at the city of Busan in Goguryeo after three days of sailing.

When the Japanese thought that they would soon conquer Goguryeo, they were hit head-on, and met their opponents in Dacheng, and the shepherd of Dacheng was Li Hengfu, the son-in-law of the famous Goguryeo anti-Japanese general Quan Li, this old man, like his father-in-law, was a talented person who could write and martial arts. When he learned that the Japanese army was rapidly advancing, he knew that his thousands of people would definitely not be able to resist, but fortunately, Dacheng was located in a mountain basin, and he wanted to delay the speed of the Japanese army's attack first. He first sent people to ambush a large number of fire-setting equipment such as fire mines, trains, and firebirds at the mouth of the basin in front, and then cut off a small river at the exit of the basin and built a dam, and the remaining 3,000 people defended the fortified city, intending to carry out a heavy attack, and then retreat to flood and slow down the attack of the Japanese soldiers.

The Japanese army arrived at Dacheng under the leadership of the forward Sakai Ieji, Li Hengfu had already closed the four gates of Dacheng, blocked the east and west gates, leaving the north gate to retreat, leaving the south gate to lure the enemy, and the people in the city had already withdrawn. Looking at the small town in front of him, the Sakai family sneered again, and the artillery they brought was lined up, and they bombarded the small city for half an hour, and then more than 10,000 people rushed straight over. Since Li Hengfu is prepared, he will naturally not suffer too much loss, but the south gate is not blocked after all, and it has been under bombardment for a long time, and it is a little shaky, but it is not a dead guard, and it is still possible to resist for a while. When the Japanese soldiers approached the city wall, Li Hengfu gave an order, rolling wood, stones, bows and arrows, and muskets fired together, and the Japanese soldiers were killed and wounded by hundreds of people. Sakai Ieji is also a fierce man, and no matter how many people die, he commanded the Japanese soldiers to surge upward wave after wave like a wave, Kankan fought for nearly four hours, when it was about to get dark, the south gate was finally breached, Li Hengfu commanded the Goguryeo soldiers to retreat while resisting, and after leaving the north gate, it was like a complete rout, and the soldiers scattered and fled.

The Sakai family took advantage of the situation to occupy the castle, and when they saw that it was getting late, the Japanese soldiers stayed in the city, after all, the weather was already a little cold at this time, and there were houses in the city, so it was warmer than living outside the city. After a day of fighting, the Japanese soldiers were also a little tired, and soon after they were stationed, they entered the dream, and the tragedy began. In the middle of the night, suddenly a cannon sounded, and the Goguryeo soldiers hidden in the cave of the city wall pushed out the prepared artillery, and there was a fierce bombardment of the city, and in an instant, the entire Dacheng fell into a sea of fire. Sakai Ieji panicked in his sleep, led the soldiers out of Tatsu Castle, counted the soldiers, and lost more than 2,000 people, so he had to be stationed outside the city and wait for Yagyu to reprimand.

When Yagyu Muneju and his main army arrived the next morning, he was furious and slapped Sakai Ieji, and then ordered Honda Tadamasa to lead 30,000 men to replace Sakai Ieji as the vanguard and continue to attack northward. Honda Tadamasa was afraid of falling into Li Hengfu's trick again, because he didn't know how many soldiers and horses Li Hengfu had, Honda Tadamasa held 30,000 people into a group to attack forward, and when he reached the bottom of the small basin, the road became narrower and narrower, and the more the Japanese soldiers walked, the more concentrated the people, and heard a thunder, Li Hengfu's dam in front of him exploded, and the monstrous river flooded along the small basin, so frightened that Honda Tadamasa's face turned white, and 30,000 people were drowned nearly 10,000 people, and the end was worse than Sakai Jiaji.

It was not only Honda Tadamasa who brought bad news to Yagyu Sotsuri, but also the logistics troops who had just walked to the entrance of the small basin were also attacked, and on the narrow road at the entrance of the small basin that spread for several miles, more than 1,000 Goguryeo soldiers threw all the ignition equipment at once to the cart full of grain and *, and in the chaotic sound of shelling, the Goguryeo soldiers rushed over without fear of death, and after a burst of fire, slashing, and shooting, the logistics brigade of the Japanese soldiers suffered heavy casualties and lost more than half of the baggage materials.

Yanagi Zongju never dreamed that the small Dacheng would let his head bleed, so he had to pause and rest, the food could be solved on the spot, and the guns had to wait for the arrival of the mainland, but as soon as the grain robbery happened, the Japanese army was completely caught in the sea of guerrilla warfare, and Li Hengfu's slow plan succeeded.

The news of the landing of the Japanese soldiers in Busan soon reached Seoul, and the newly enthroned Goguryeo king Yi Liang panicked and hurriedly gathered his ministers to discuss and ask the Ming Dynasty for help. At this time, Fan Wencheng's role was revealed, and with his unbroken tongue, he persuaded the Westerners to invite the Jurchens to enter the country to help. As a result, the Jurchens began to legally enter Korea and began to fight together with the Goguryeo, and carried out bloody killings for many years.
