The Young and Vigorous Eighth Prince

Duo Layue's children were already four years old, almost five. She had lived in Dayan for three months and returned with a bulging belly.

During this period, in addition to Duo La Yue Er's visit, Luo Yun Xian and Li Chang Le also took time to visit Jiang Fan. They all left with pregnant bellies in the end.

In the past three years, each of Jiang Fan's four wives gave birth to a child. Jiang Fan now had several more pairs of children.

Not long after Duo La Yue Er returned to Bei Meng, Bei Meng was invaded by the Jurchens. After being forced into the Northern Barbarian Land by Silla, the Jurchens found a bitter and cold place in the Northern Barbarian Land and survived.

But they were unwilling to stay in such a cold and bitter place and wanted to counterattack. However, after hearing that Silla was destroyed, they gave up the idea of ​​counterattack.

After all, they had just recovered their strength, and they might not even be able to defeat Silla, so how could they defeat Dayan, which was more powerful than Silla.

That was the Great Yan that destroyed Silla in just a few months, so they set their sights on Northern Mongolia.

They thought that if they could occupy a part of the Northern Mongolian grassland, Northern Mongolia would be helpless against them. You know, the cavalry they trained now are almost invincible.

What they were most proud of was their cavalry. They had had several conflicts with the Northern Mongols, and they always won.

Therefore, they came up with the idea of ​​plundering the Northern Mongolian grasslands, but the cavalry of the Northern Mongolian grasslands were indeed no match for them, and the large tracts of grassland bordering the Jurchens were all taken away by the Jurchens.

The tribes in Northern Mongolia passed the message of seeking help to the royal court of Northern Mongolia. After receiving the news, Dora Yue'er wanted to gather cavalry to launch a counterattack against the Jurchens.

But after thinking about it, he still opened his mouth to ask Jiang Fan for help. The Northern Mongolian cavalry would probably be no match for the Jurchen cavalry. If they suffered heavy losses, the Northern Mongolians might really take advantage of the situation and rise up.

But she knew Jiang Fan's methods and strength, and she believed that as long as Jiang Fan took action, the small Jurchen tribe would be doomed to failure.

After receiving the letter for help, Jiang Fan did not go out in person. A small Jurchen tribe was not worth his effort. After all, his main task now was to develop Dayan.

He sent out Chu Chengren, the third son of the Chu family. Now, Jiang Fan had a lot of generals available, including the Seven Tigers of the Chu family, the Five Tigers of the Ning family, and the generals he selected from the White Robe Army.

Any one of them can easily defeat all foreign enemies. Chu Chengren led 100,000 people to the border between the Northern Mongolian grassland and the Jurchens, which is the Taigurle Mountains not far from the Hezhou Pass.

The 100,000 men were all selected from Hezhou Pass, so there was no need to worry about acclimatization. When the army set out and arrived at the Taiguler Mountains, they encountered the vanguard of the Jurchens.

They were looting a Northern Mongolian tribe of tens of thousands of people. At that time, there were more than 10,000 Jurchen cavalrymen, who killed tens of thousands of Northern Mongolians without them having the ability to fight back.

Chu Chengren sent out 5,000 cavalry to harass the Jurchen cavalry, luring them into his trap, and then used the Maxim army to surround and kill them, and more than 10,000 Jurchen cavalry were completely wiped out.

The Yan army led by Chu Chengren did not suffer any casualties. After the battle, Chu Chengren was filled with emotion. With such a powerful weapon in hand, Great Yan could easily conquer the entire world, let alone destroy the Jurchens.

After destroying the Jurchen vanguard, Chu Chengren rushed all the way towards the Jurchen habitat. The 100,000-strong army was unstoppable and the Jurchens had no power to resist wherever they passed.

It took Chu Chengren only two months to capture all of the nearly one million Jurchens, and the more than 200,000 manpower of the Jurchens were also disintegrated.

According to Jiang Fan's idea, Chu Chengren moved the Jurchens to the Central Plains, and then left some of them there. In addition, he moved a group of gold diggers from the Central Plains to where the Jurchens were.

Although the place where the Jurchens lived was harsh and cold, it was rich in minerals and had many untapped resources, so it was not a completely useless place.

With the rapid development of Dayan, the people of Dayan also began to flock in all directions.

It is a barren land to others, but to the people of Dayan who have broadened their horizons, it is a land of wealth with gold everywhere!

After the Jurchens were annihilated, Jiang Fan had already successfully developed welding machines and welding rods and put them into mass production. The research of giant steel ships was also put on the agenda.

After several years of development and improvement in steelmaking technology, Gatling guns were produced.

Navigation technology has also been greatly improved. Jiang Fan chose a sunny early spring day and led 200 warships, 300 supply ships, and 200,000 troops and logistics personnel to Japan!

The war to destroy the Japanese has begun! Chu Chengxiong and Chu Chengrui are accompanying them this time, while Chu Yan'er, Su Yuqing, Zhong Ling, and Ning Xinyu stay in the capital.

Qing Lingxiu followed Jiang Fan to Japan. At this time, Qing Lingxiu was already 20 years old and she had many suitors, but she was stubborn and did not accept anyone's pursuit.

Zhong Ling also knew what Qing Lingxiu was thinking, so after telling Chu Yan'er about it, Chu Yan'er didn't say anything, but arranged for Qing Lingxiu to be taken care of by Jiang Fan.

A mighty fleet of five hundred ships headed towards Japan. The reason why Jiang Fan scheduled the departure time in spring was because he was afraid of the impact of the monsoon and the occurrence of hurricanes.

With the current bearing capacity of wooden giant ships, a hurricane of level 8 or 9 could tear the giant ship apart. Even a steel giant ship could capsize.

Unfortunately, there is currently no satellite that can predict the weather. Even with the experience of veteran seafarers, it is impossible to accurately predict the occurrence of typhoons.

Therefore, it is of course best to sail on the sea to avoid the hurricanes in summer and autumn. Jiang Fan does not want to invade Japan and eventually destroy the country.

The current steam-powered warships can sail over a thousand nautical miles, or even more. Mechanically powered ships that are more powerful than steam power are not yet possible.

Once the steel warships are manufactured, they will have a longer range with the use of fuel-powered steam. Jiang Fan's fleet departed from Dinghai Island, about 1,500 miles from Japan, which is about 750 kilometers. If converted into nautical miles, it is about 400 nautical miles.

Therefore, it is no problem for a steam-powered giant ship to make a round trip to Japan. If it is assisted by sail power, the use of coal can be further saved, and even two round trips can be made without any problem.

The fleet was sailing on the sea. Although Qing Lingxiu had received seasickness training, the long-distance voyage still made her feel uncomfortable, and her pretty face turned pale.

Seeing her like that, Jiang Fan could only accompany her on the top deck to enjoy the breeze and slowly let her get used to sailing on the sea.

Qing Lingxiu was indeed a martial artist, with the strength of a first-class master, so she adapted to the sea voyage after a few days. Qing Yucheng, who was following beside her, also adapted quickly.
