If His Majesty Li Er's army was about to arrive in Liaodong, it would be three months later. This is also the reason why His Majesty Li Er had to send a vanguard army. Two and a half months were too long. Three months, every extra day was an extra chance for Quan Gai Suwen to level the Goguryeo court.

Even if the vanguard army marched rapidly, the speed of the vanguard army was only two-thirds faster than the army, and they did not have to travel like yesterday. If the army ran to Liaodong in this way, they would probably have been abandoned by just rushing to the road.

The marching process of the vanguard army was very monotonous, and the materials needed by the vanguard army were also sent to various prefectures along the way. As soon as the army arrived, it took a little supply and then set off for Liaodong immediately.

The budget for the itinerary for more than 40 days was relatively accurate, but by the time Li Daozong and Xuan Shijing brought the vanguard army to Liaodong, it was already the end of August.

The climate of Liaodong in August is no different from that in Chang'an and June. If you wear too thick clothes, you will feel sweaty. Pingzhou City is close to the Luan River, so taking a bath is convenient. The Pioneer Army only rested in Pingzhou City for a whole day. Then Liu Hongji wrote to Li Daozong, saying that he would start doing serious business.

The Tang Dynasty's marching in Liaodong cannot be concealed by Quan Gai Suwen, so the army is already on the road. Quan Gai Suwen cannot receive the news, but Quan Gai Suwen must have been unable to understand the position of the vanguard army. Otherwise, Li Daozong and Xuan Shijing will be useless as the vanguard army.

When Liu Hongji's handbook was delivered to Li Daozong, Li Daozong called Xuan Shijing and another deputy general to the tent.

"One day the army arrived in Pingzhou, Liu Hongji's handwritten letter had been delivered to the general. Three days later, at noon, Liu Hongji would lead the navy to attack Beisha City, and let the general lead 5,000 troops from the ground and attack on both sides. The general carefully looked at the map and felt that Liu Hongji's deployment was appropriate. What do you two think?" Li Daozong looked at Xuan Shijing and another deputy general.

"General, can you let the last general look at the map?" Xuan Shijing stood up and bowed and asked.

"Here." Li Daozong pointed to the desk behind him. The desk was placed on it. The map of the desk in Liaodong and Goguryeo.

Obtaining Beisha City is a must-do. If you occupy Beisha City, you will insert a sharp sword into the sphere of influence of Goguryeo in Liaodong. If you keep this sharp sword, you will greatly restrict Goguryeo's actions in Liaodong.

"What? Do Deputy General Xuan has any suggestions?" Li Daozong saw Xuan Shijing staring at the map, frowned, and couldn't help but ask.

"Bisha City is the closest city to the Andong Protectorate of Pingzhou, but after occupying the Andong City, Jian'an City in the south of Beisha City quickly reacted. Jian'an City is a military city in Goguryeo on Liaodong Island. Once there is any movement in Beisha City, Jian'an City will react immediately. We are just a vanguard army. Even if the navy is added, if we fight against the combined forces of the two cities, we will have more strength but not enough strength in the south." Xuan Shijing said: "I don't know what countermeasures did Liu Hongji and the general tell me in this way?"

Hearing Xuan Shijing's analysis, Li Daozong's eyes were filled with some appreciation and nodded to Xuan Shijing: "Yes, Andong City is not far from Beisha City. If he cannot conquer Beisha City within three days, then it is very likely that our vanguard army will fall into the deadlock of the siege of Beisha City and Jian'an."

"And once the war begins, the food and grass of our vanguard army is also a problem. In the final analysis, our number is not large. We go from Pingzhou to Beisha City and pass by Liucheng halfway. We can hoard some food and grass in Liucheng for later use. But even so, even if we go deep into Beisha City alone, even if we can bypass Huaiyuan Town and march to Anshi, how can we ensure that people who do not back Anshi City find the army?" Xuan Shijing touched his chin and thought.

"There is no need to worry about this. When we passed through Anshi, the army changed to a night departure. In this way, we can avoid the spies in Anshi City as much as possible." Li Daozong said: "Now we have arrived in Liaodong. Although the guards are on the road, I believe Quan Gai Suwen has already figured it out. The guards in these cities near the Tang Dynasty in Liaodong must be different from the past. Fortunately, we have three days, even if we march to Beisha City, it is enough."

"General, why don't we go to Beisha City in another way?" Xuan Shijing suggested.

"Change another?" Li Daozong was puzzled. Now that he had arrived in Liaodong, how could he go to Beisha City?

"It requires Lord Liu to cooperate. The navy set out from Dengzhou to Liaodong, so Lord Liu set the time three days later. General, why not let Lord Liu send ships from Dengzhou to Pingzhou immediately. The Luan River flows into Wuhu Sea here. There is a port here. Although it is not big, dozens of ships can still be accommodated. Use ships to transport the 5,000 vanguard troops directly to Beisha City.

"These five thousand vanguard troops are all infantry soldiers, and they are afraid they cannot adapt to the strong winds and waves on the sea. Moreover, the ships are just transporting infantry and have no combat power at all. If they encounter Goguryeo warships on the sea, they will be caught in one go. This move is too dangerous and inappropriate." Li Daozong denied Xuan Shijing's proposal.

"General." Another deputy general said, "I think that it's not impossible for Deputy General Xuan to improve his proposal?"

"What's your idea?" Li Daozong asked.

"Our vanguard army is not water-free, but it does not mean that we cannot take a boat. The last general means that the attack on Beisha City will be delayed by one day. The vanguard army will take a boat to Beisha City first and choose a secret place to rest. One day should be enough to let the soldiers of the vanguard army recover, and then cooperate with General Liu Hongji to attack Beisha City." The deputy general said: "In this way, it will only take a day and a night to let the scouts guard against the spies in the direction of Beisha City, and there is still some time to understand the details of Beisha City."

Li Daozong thought about it for a while, then nodded: "This plan is feasible. I will write a letter to Liu Hongji to cooperate with the vanguard army."

"General, in addition, we have to plan for the reinforcements in Anshicheng." Xuan Shijing said: "It is impossible to shake Anshicheng with the vanguard army. Anshicheng has many soldiers and generals, with tall walls. The city is stockpiled with food and grass in the city. Not to mention the vanguard army, even if His Majesty personally led a large army to attack Anshicheng, it would be impossible to make a decision in one battle. We have to make plans early."
