Although the goal of the battle was to support Liaodong, Liu He also knew that the enemy army must be tightly sealed along the way, especially the sea route from Qingzhou to Liaodong, and the other party must have laid heavy troops, so it is almost impossible to reach Liaodong directly.

Although with the combat effectiveness of the Han army, even if Liu He's 200,000 troops fought against the coalition forces of different races alone, they would eventually be able to win, but Liu He did not intend to do so, because a direct hard encounter would cause his own side to suffer heavy losses, Liu He did not want his loyal and brave soldiers to suffer more losses, and the most clever thing in the war was to exchange as few losses as possible for as much victory as possible.

Therefore, after discussion, Liu He decided to adopt the strategy of encircling Wei to save Zhao, leading the army to attack the empty Baekje in the rear, and then using Baekje to attack Goguryeo.

Of course, the most important thing is that Liu He's army has a very strong mobilization ability, mobilizing 200,000 land and water troops in just one month, and advancing from Dongnae to Baekje by water, it will take two days at most, which is almost equivalent to a month in advance, Liu He can successfully attract the forces of Goryeo, Silla and Jurchen as long as he defeats Baekje within a month, which will greatly weaken the pressure on Liaodong, not to mention, Liu He has already received news before the expedition, Zhao Yun's injuries are basically stable, Although it is not possible to lead the army to fight in a short period of time, it is still no problem to deploy defenses and boost morale, so the current situation in Liaodong City is basically stable, even if you count the forces of Goryeo, Baekje, Silla and Jurchen, it will be no problem to hold on for another two or three months. Without these four tribes, Liaodong would only face Xianbei's forces alone, and if nothing else happened in this situation, as long as Zhao Yun's injuries were completely healed, he might even launch a counterattack, let alone defend.

This means that as long as Liu He is sure that he will destroy Baekje in a short time, this expedition to the east will be invincible.

So Liu He's army of land and water marched to the mouth of the Baekje River.

Baekgang Estuary is the name of a sea area called Baekchon River in the coastal area of Baekje, Baekgang Estuary is the port where Baekje landed from the sea, which is also the largest port in the Samhan (Goguryeo, Silla, Baekje) area, and most of the trade between the Han and the Han Dynasty in the past was through the Baekgang Estuary, but later the Samhan and the Han declared war, and the trade naturally ended, and now it has become the largest military port in Baekje, otherwise it will be connected with Silla and Wa Kingdom at sea.

Since it was a military port, it was naturally indispensable to garrison troops, and there were 50,000 naval troops stationed here, including 20,000 in Baekje, 10,000 in Silla, and 20,000 naval troops in the Japanese Kingdom, with a total of more than 5,000 large and small warships.

In fact, the commander of the three-Korean coalition army, Eulji Moondeok, had already prepared for Liu Hehui's landing from here, so he stationed heavy troops and sent the first general of Baekje, Hei Natsuno, to personally take command.

In addition, there were also Silla's general Daibo, Shimazu Yoshihiro of Wa Province and others as deputy generals.

Liu He naturally knew that Heiya Changyuki was a very famous general in history, and Jiebo and Shimazu Yoshihiro were not unknown, so he did not relax his vigilance in his heart, but carefully formulated a battle plan to destroy the enemy in one battle.

However, the problem now is that Liu He's army does not have a commander who is good at surface warfare, but fortunately, Xue Rengui can be familiar with water warfare without a teacher, and Lu Su and Sun Shangxiang are also very proficient in water warfare.

So Liu He proposed that Xue Rengui be the commander of 20,000 naval troops to be responsible for luring the enemy, and generals such as Huang Zhong and Sun Shangxiang who were good at sniping were responsible for sniping and killing enemy generals, and the rest of the generals were responsible for ambushing.

"Xue Aiqing, as long as you can successfully lure the enemy army to the sea twenty miles outside the mouth of the Baijiang River, you will be considered the first merit!"

When making the plan, Liu He didn't forget to say this to Xue Rengui.

However, at this moment, Guan Yu on the side spoke: "Your Majesty, Weichen is also familiar with water warfare, and is willing to lead the army to be responsible for luring the enemy. ”

Liu He suddenly laughed in his heart when he heard this, he naturally knew that Guan Yu cared about Xue Rengui on the surface, but in fact, he was not convinced by Liu He's appointment of Xue Rengui as the commander in the army, so he wanted to compete for credit.

In fact, what Liu He wants is for Guan Yu to take the initiative to stand up, because as Guan Yu said, Xue Rengui, as the deputy commander of the three armies, is indeed not suitable to lead the army to lure the enemy, Liu He originally considered letting Guan Yu be responsible for luring the enemy, but he knew that Guan Yu was not satisfied with Xue Rengui, if Xue Rengui made a decision directly and ordered Guan Yu to fight, with his temperament, he was likely to refuse directly, even if he took the order to go, it would definitely violate the military order and bring unnecessary losses to the Han army, so Liu He deliberately proposed to order Xue Rengui to lure the enemy to achieve the radical general.

Now that Guan Yu really stood up, Liu He was very happy in his heart, but on the surface, he said: "Although General Guan is familiar with water warfare, after all, he has the experience of fighting along the river, and he is not suitable for sea combat, not to mention that the general is now old, and I am afraid that he is also a little powerless in combat......

Guan Yu has always been proud, where can he stand such words? Immediately said proudly: "Please rest assured, if the old minister is unfavorable in this battle, he is willing to be dealt with by military law!" ”

"In this case, then let the general lead the army to lure the enemy, and the general must remember that this battle is only to lure the enemy, but not to fight with the enemy......"

"Your Majesty, rest assured, the old minister knows that he will definitely let the enemy obediently come to the ambush site. It's just that the terrain is open, and the enemy can easily discover our whereabouts, even if we lure the enemy over, they will definitely look away, what use can it be? ”

Guan Yu looked puzzled and asked Liu He.

Liu He said with a confident smile on his face: "Old general, you just have to go, when the enemy arrives, there will be a sudden fog there, and there will be no trace of our army at all, and the old general will only listen to the sound of drums, and then he can lead the army to launch a counterattack." ”

"Is it really going to be foggy?" The puzzled look on Guan Yu's face was even worse, and he muttered.

Liu He didn't respond to this sentence, but just said: "General Guan, you just lead the army to lure the enemy, as long as the enemy arrives, it will be your first merit, if there is no fog at that time, it is my fault, and I will be fully responsible." ”

“...... Since His Majesty said so, the old minister obeyed the order, and this trip will definitely not disappoint His Majesty. Guan Yu arched his hand at Liu He, took the military order, and then deployed to lure the enemy.
