In short, after the Jiannu army took Ningyuan City, there was no opponent who could be their enemy outside the entire Shanhai Pass, so nearly 200,000 Jiannu troops immediately divided their troops into two ways and rushed towards Shanhaiguan.

Therefore, the situation in Guanning could not allow Xiao Tianjian to continue to attack the north step by step in an orderly manner, so after Xiao Tianjian considered it, he ordered Luo Li to be the vanguard, first crossed the area controlled by the government along the way, and rushed directly to Hejian Mansion and Li Xin, Diao Zheng's middle route army to make peace, and then immediately marched in the direction of Shanhaiguan, not for the purpose of attacking the city along the way, unless they encountered the official army out of the city to intercept, otherwise they would first rush to the Shanhaiguan area and Yan Chongxi and Lu Xiangsheng to make peace.

At this point, Xiao Tianjian did not disappoint Lu Xiangsheng, Xiao Tianjian faithfully fulfilled his promise to Lu Xiangsheng, the grievances between Dazhong and Daming can be temporarily put aside, but in dealing with Jiannu, he Xiao Tianjian should focus on national affairs, he can give up overthrowing the Ming Dynasty first, but he must first resist the Jiannu army to infiltrate the land of Yanyun, and he will not repeat the mistakes of the year.

Therefore, before the Right Route Army entered the territory of Hejian Province, Luo Li led more than 10,000 guards to the city of Hejian Mansion and the Central Route Army to make peace.

As soon as Hejian Mansion was taken, Li Xin, Diao Zheng, Luo Li and other generals immediately left Hejian Mansion in accordance with Xiao Tianjian's order, and rushed towards Shanhaiguan.

Xiao Tianjian led the remaining soldiers and horses of the Right Route Army to continue to attack Cangzhou along the Grand Canal step by step, using the Grand Canal that is still usable today, transporting various strategic materials with countless boats and transshipment to the north to support the duel between the Dazhong Army and the Jiannu Army in the north.

Although Xiao Tianjian was also anxious, he wanted to rush to Shanhaiguan as soon as possible and personally command the decisive battle against the Jiannu army, but he also knew the importance of the Grand Canal for the decisive battle, which can be described as a key battle for the future of the Han nation. And Huang Taiji also clearly announced in Jiannu that after they entered the customs this time, they would not follow the way of entering the early years of the Kou, and retreat to the outside of the pass after a full plunder, this time they would attack the Guannai, and completely occupy the Guannei, if the war went well, they would defeat the Ming and Dazhong Army, and continue to move south, until the entire Central Plains was controlled in the hands of their Jiannu.

This goal is not grandiose, and it also completely exposes Huang Taiji's ambition for the Central Plains, of course, his ambition is also the ambition of many Jiannu chieftains, so Huang Taiji used his prestige and status in Jiannu to encourage all Jiannu, with a must-win mentality, opened the prelude to this southward entry.

But relatively speaking, Xiao Tianjian's side, although he also gathered as many available troops as possible, after all, many places in China have not yet been pocketed by them, especially the southern provinces, the local government loyal to the Ming Dynasty, and they are still eyeing the newly established Dazhong Dynasty and want to restore the dominance of the Ming Dynasty, so he had to be distracted and leave some troops and horses in the south to prevent the Ming forces in the southern provinces from trying to take advantage of this opportunity to restore their rule.

Even in Shaanxi, he had to pay attention to the movements of the thief Li Zicheng, now he and Li Zicheng have completely turned against each other, Li Zicheng's side, will not sit back and watch such a great opportunity, and Xiao Tianjian will not compete for the world, so although the total strength of the Xingtian Army is far more than the Jiannu side, but the strength that can be used for the decisive battle in Jiannu in the north is not more than half of the Jiannu army, and he also has to guard against the officials and soldiers loyal to the Ming Dynasty stabbing in the back, all kinds of circumstances can be said to be not beneficial to him.

But even if this pot of rice is a pot of raw rice, he Xiao Tianjian must eat it, because once Jiannu is allowed to take the lead in the land of Yanyun, if he wants to restore the rule of the Han people in the north in the future, he doesn't know how much manpower and material resources will be spent to drive Jiannu back to the gate again, and it is even more distant to destroy Jiannu.

Therefore, the importance of this Armageddon far exceeds the importance of all the major wars since he rebelled, and it is no longer just a matter of whether he can survive the Great China and the DPRK, but its significance has risen to the level of whether the entire Chinese nation can continue to stand on the top of the world's nations in the future.

In addition, because of the way the Xingtian Army was built and the equipment, it was destined that the Xingtian Army's demand for material supplies should exceed the demand for material supplies of any army in this era.

War is to fight logistics, without perfect logistics supply, the war can not continue, not to mention that when Jiannu goes south to enter the customs, they can have no psychological burden, and completely rely on looting to supplement their army needs, and they don't have to worry too much about things that will lose the hearts of the people, the big deal is that they can retreat to recuperate outside the customs, but he Xiao Tianjian has to consider the problem of people's desire, and when he goes north, he can not rely on capture to supplement military supplies, but rely on the material replenishment in the rear to meet the needs of the army.

In that case, to support the Northern Expedition of 100,000 troops, at least to mobilize several times the manpower and animal power of the army, to provide support for the army, with the current financial strength and manpower of the Great China and North Korea, if this is done, the drag can also drag down the newly established Great China and North Korea, so if he wants to be in this decisive battle, he has to pay attention to the Beijing-Hangzhou Grand Canal, which has become the lifeblood of the future of Great China at this time. Before he established a usable sea force, he could only rely on the Beijing-Hangzhou Grand Canal to deliver various strategic materials to the front-line soldiers to ensure the needs of this battle.

Sometimes Xiao Tianjian himself thinks that if he was left by God in the area of Nanzhili or in the area of Fujian and Guangxi in the south, he would definitely choose to establish a strong maritime force first, and then use sea ships to transport a large number of trained troops to the north and smash the nest of Jiannu, but it is a pity that there is no if, God left him in Shaanxi, where birds do not lay eggs, he can only choose to establish strength in the inland first, and now he can only use this way to block Jiannu from the customs first.

Therefore, Xiao Tianjian has a feeling that time is not waiting for me every time he thinks of these things, and he wants to build a naval force that can cross the sea as soon as possible, and gallop on the sea for the proud world of Great China in the future, and attack the city.

After completing the adjustment, Xiao Tianjian sent Luo Li to set off, and he immediately continued to lead Liu Yaoben and the remaining soldiers and horses on the right side, and launched an attack on Linqing City, Linqing was still a small city at this time, only a county under the rule of Dongchang Mansion, but the Ming Dynasty built five grain warehouses on the Grand Canal in Linqing, so the importance of this small place was highlighted, this is an important node on the Grand Canal, and the imperial court officials have paid great attention to it. Therefore, a group of troops disproportionate to this small city were also placed here, and there were nearly 10,000 officers and troops stationed here, so it took Xiao Tianjian nearly five days to attack Linqing, and the Linqing defenders finally surrendered.

Although the offensive of the entire Right Route Army can be said to be very smooth, as the Right Route Army penetrates deeper and deeper into Shandong, the battle line has also begun to be rapidly lengthened, and it is not very difficult for Xiao Tianjian to lay down the cities along the way, but as the battle line is longer and longer, it has become more and more difficult to protect the transportation safety of the canal.

With the development of the war along the entire Grand Canal, a large number of officers and soldiers were defeated by the Xingtian Army again and again, although many officers and soldiers chose to surrender to the Dazhong Army, but there were also many officers and soldiers who turned around and changed their careers to become rogues after the defeat, and continued to wander and loot all over the Grand Canal.

Although Xiao Tianjian ordered the Dazhong Army Sailors to also transfer into the Grand Canal, responsible for protecting a large number of requisitioned boats to transfer materials, but these water thieves can use the various lakes dotted along the Grand Canal to hide their whereabouts, and constantly attack the Cao boat fleet, these water thieves are not actually loyal to the Ming Dynasty, they are more often out of their own interests, there is no organization and discipline at all, On the canal, they grabbed what they could, and if they couldn't, they set fire to the ships of the Dazhong Army, and it can be said that this kind of sabotage was only out of revenge against the Dazhong Army, and there was no reason at all.

Therefore, their actions caused great damage to the follow-up material transfer and replenishment of the Dazhong Army, the ships transporting materials were robbed or burned one after another, and the boat people who served the Dazhong Dynasty were also repeatedly slaughtered by these water pirates, so that Xiao Tianjian could receive the news of the robbery of the Cao boat almost every day, which made Xiao Tianjian very angry.

Originally, it was very difficult for the newly established Dazhong Dynasty to collect these materials by all means, and it was only through the consumption of a large amount of silver money that they were organized to transport them to the north, but on the way, they were looted by these unfashionable water bandits, and even set fire to them in vain, and the losses caused to the Dazhong Dynasty were so great that it was almost impossible to count them in numbers.

Therefore, Xiao Tianjian often accepted the surrender of the official army, and immediately disbanded it and resettled it to the local area to restore agricultural production as much as possible, but when this situation happened repeatedly, Xiao Tianjian had to change the initial strategy, began to reorganize these surrendered soldiers, sent capable officers under his command, took over these surrendered troops, and instead placed them along the canal, responsible for clearing out local bandits and water thieves, and protecting the safety of canal shipping.

In this way, the number of troops can be said to have swelled again and again during this time, and it also consumed a large number of materials transported north by the Xingtian Army.
