By the time Lu Ning arrived at Lelang City, Yang Ye had already conquered the four strongholds held by the Goryeo on both sides of the Cheongchon River, and sent troops to Pyongyang City.

Following the actions of the Eastern Army of Yang Ye Town, there is also a large thunderbolt battalion that the Liaodong Army has just deployed.

Ten bronze cannons of the Great Perak Battalion, similar to the principle of the so-called Napoleonic cannon in later generations, theoretically speaking, that is, in the Qin and Han dynasties, there was the thinking of later generations, and the dominance of the lord to mobilize resources, this kind of bronze cannon was manufactured without any problem, of course, unlike the real gunpowder era, this bronze cannon can only fire solid bullets, and the power is greatly reduced, but it is a sharp weapon for field warfare and siege.

In addition to the Beijing Garrison Battalion, the two most important border armies of the Shaanxi Western Army and the Liaodong Army have begun to deploy the Great Perak Battalion, with the Shaanxi Western Army having two battalions and the Liaodong having one battalion.

In the Eastern Expedition to Japan, whether to still secondment the Great Perak Battalion of the Liaodong Army, Lu Ning has been considering.

There are ten bronze cannons, and the attack on Dongying's city defense is naturally smoother, and the tribal army is brave, but the siege has always been a weakness.

But if you bring these ten copper cannons over, once the Eastern Expeditionary Army is defeated, the copper cannons will eventually fall into the hands of the Dongying people, which is inevitably a little bad.

Although, invading the territory of Dongying from north to south, the difficulty will be slightly lower.

Speaking of which, it was the powerful Yuan Dynasty, and the failure of several expeditions to Dongying was not only due to hurricanes, but mainly to invade Kyushu in the south of Dongying, which made the Dongying people aware of the great threat, and soon all kinds of scattered forces united to gather the strength of the whole country to defend.

In the case of logistical difficulties, the Yuan people were attacked by waves of Dongying people, and even the archers that the Mongols were proud of quickly ran out of arrows and had to board the ship to retreat, and their Eastern Expeditionary Army never really stood firm.

Although his strategy was from the north to the south, using the excuse of conquering the Ezo people to confuse the Toei people in a short period of time, in addition, the main cities and prosperous areas of the Toei people were in the south, and there were only a few strongholds in the northeast of Honshu Island, and the rest were still the territory of the Ezo people's activities, and the entire Kyushu Island was even more entrenched by the Ezo people.

Therefore, it was inevitably difficult for the Dongying people to find out the intentions of the Great Qi in the early days, and it was even more difficult for them to resist the "invasion" of the Great Qi with one mind, so that the Eastern Expeditionary Army had time to fight steadily and occupy or build a solid stronghold in the north.

But despite this, the Dongying people are not a barbaric land inhabited by tribes, but a country with a long history, a gradually evolving but very stable political structure, and the Yamato nation with a strong sense of ethnic identity, and even like Middle Earth, the He people also have a self-centered barbarian distinction, and the barbarians in their eyes are the Ezo people in the north.

The shogun "Sei Daishogun", who later became the de facto ruler of Toei, has long appeared as a temporary official position, but the current name does refer to the Ezo people in the northeast of Honshu Island and Hokkaido, and even in the past, the Ezo people were all over the four islands, and now they are forced to shrink northward.

The first generation of the Great Shogun was to conquer the Kanto Ezo, which threatened Kyoto.

Nowadays, the Ezo people in the Kanto region have become extinct, but their folk customs naturally have traces of mixing with the Ezo people, and the fierce Kanto samurai group is gradually appearing on the stage of history.

Of course, according to intelligence, the Dongying people today are different from the invasion of the Yuan Dynasty in history, and they do not have much experience in large-scale wars, and even the so-called "joint war", many times, the opposing sides take a one-on-one approach, especially the confrontation between the samurai leaders, which is similar to the Romance of the Three Kingdoms in the Central Plains.

After all, the current population of Dongying, according to later estimates, is only four or five million, and it may even include false statistics of the Ezo people.

It was not until after the Hogen Rebellion, the Genhei War, and other great battles in which the top elites of the Toei competed for supreme power and even created the shogunate, that the bloody massacres of the Toei people began to appear, such as the war, the large-scale military prostitutes, and the scorched earth policy.

But having said that, the bronze cannon is now brought to the three islands of Dongying, and it is not safe after all.

As for why we say Toei Mishima, because of Hokkaido, it is naturally not the island of Toei today.

Even the northern part of the island of Honshu cannot be considered Japanese territory.

……

While thinking about these questions, Lu Ning went to Longgang Town, which is located at the mouth of the Taedong River, a hundred miles southwest of Pyongyang.

Originally, it was just a small fishing village, where the Pu family and the Central Plains traded, and was built as a transit point, and now, it has become a military port of Daqi.

Zhang Bao, the training envoy of the town regiment, also serves as the head of the town's water division, of course, the water division of Longgang Town, is just some small river boats, and his future responsibility is to inspect the Datong River waterway, arrest water thieves, and check and prevent displaced people from crossing the river.

In addition to the Yulin Army, who accompanied Lu Ning to Longgang Town, there were also the Jin family, Empress Xiao, Yi Lazy, Qianqiu Hall and his entourage.

From the time the Jindong Army arrived at Lelang City to prepare for an attack on the Goryeo stronghold, the Goryeo mission was placed under house arrest.

Now the members of the mission who followed Lu Ning to Longgang Town are only Jiang Gongzhen and his son, and the rest of the envoys and their entourage are all imprisoned in Lelang City.

After the Zhendong Army launched an attack on the stronghold of Goryeo on the Qingchuan River, the Park clan of Pyeongju in Goryeo officially united with several local wealthy clans and raised the banner of "Qingjun's side" to kill the traitorous ministers led by Shuangyi around Wang Zhao.

Speaking of which, the cronies around Wang Zhao, Shuangji, Cai Renfan, Wang Rong, etc., who were nominally targeted by the Hao rebels, were all in Seoul.

After arriving in Goryeo, he heard that Chai Rong had died in battle, and he was sick, so he stayed here and was reused by Wang Zhao.

Cai Renfan and Wang Rong also came from Wu Yue to defect, and they were not very ambitious literati in the Central Plains, but when they arrived in Goryeo, they became noble ministers, and they naturally forgot to return.

Speaking of which, Wang Zhao's implementation of the imperial examination system to promote talents and weaken the power of local wealthy clans in the DPRK and China, or even the direct purge of meritorious and wealthy clans later, were all proposed by these ministers from the Central Plains.

Even Wang Zhao proclaimed himself emperor internally, which is said to be the many words of the wings.

And this "head of the traitor" was originally just a small patrol officer in the previous week, following the entourage who was envoying to Goryeo, but now he seems to be the most trusted minister of the lord of Goryeo, Zheng Kuang.

The target of Park Shouqing and others who raised the flag on the side of the Qing monarch was mainly the original ministers such as Shuangyi.

Lu Ning couldn't laugh or cry at this, but now Shuangyi and the others are naturally foreign courtiers, and they do have some talents to help Wang Zhao realize the rapid convergence of Goryeo to the Central Plains system, making Goryeo's national strength gradually stronger, but the more so, the more harmful these people are to Qi people, isn't it?

Therefore, under the pretext of Qi Tianzi ordering an attack on the Goryeo strongholds along the Cheongchon River and an attack on Pyongyang, firstly, to recover the old land of the Central Plains; The second is that Wang Zhao usurped the title of emperor under the bewitchment of the ministers, and also ordered Wang Zhao to escort the ministers and others to Lelang City to ask for guilt.
