With Ruan Chengfu's help, Zhao Chongyang accepted Wu Yong's suggestion to treat the nearly 50,000 Annam naval troops differently, leaving those who were at the lowest level, serf-born soldiers and honest soldiers with free status, and transporting those who were full of hatred for the Song people to the Red River Estuary and the ship port to work as coolies.

In this way, after seven days of screening and screening, more than 20,000 Annan soldiers who were willing to serve Zhao Chongyang and them were selected.

In this way, Zhao Chongyang's army suddenly increased to more than 70,000 people. Zhao Chongyang promised them that as long as they marched bravely in the battle and were not afraid of sacrifice, after the battle, they would return their family to freedom and give them more land, so that their children and grandchildren would never be slaves again......

According to Nguyen Thanh Phu's prompt, Li Liangwu's army will arrive in more than twenty days. In order to confuse the enemy, in the afternoon after the surrender of the navy, the whole city was changed back to the banner of Annam, and the city of Annam was allowed to enter but not to leave.

Under the leadership of the locals, Zhou Dong sent countless scouts to investigate the enemy's whereabouts.

At the same time, Wu Yong asked Ruan Chengfu again: "Will the route of the army retreating south go along the Red River Valley?" ”

Nguyen Thanh Phu said that under normal circumstances, they walk along the river valley, and only when they encounter a mountain obstruction, will they take a detour. After rounding the mountain, continue along the river valley. Because there are many towns on both sides of the river valley, and the water transportation is convenient, it is convenient to solve the supply on the spot, and if the time is tight, it is not easy to get lost when marching at night.

So Wu used a plan to ask Ruan Chengfu to take two hundred ships north and find a suitable wharf to intercept Li Liangwu's army. It is said that he was ordered by the king to use a ship to take a part of the army into the city first, strengthen the defense, and give the Song people who were besieging the city the maximum damage, and after the main force arrived, the inside and the outside should be combined to defeat the Song army in one fell swoop.

Zhou Tong and Zhao Chongyang both thought that this plan was very clever, and they could deceive Li Liangwu from 3 to 50,000 soldiers without much effort, so as to reduce a lot of trouble for the big ambush behind. If you are lucky, you can also trick Li Liangwu into the ship and kill him secretly.

So Zhou Dong sent Pang Wanchun and Qiu Qionghu, who had learned the Annam language, to lead 1,000 special combat soldiers to cooperate with Ruan Chengfu's operation. Tell them to do so, and the trip will be a great victory.

Nguyen Thanh Phu and others took 5,000 sailors and 200 warships of the Annam navy, changed into the clothes and banners of the Annam army, and left.

Ten days later, Nguyen Thanh Phu and his fleet arrived at a small town called Stone City, which was an important supply depot for Annam's army. After they waited here for three days, at noon on the fourth day, Li Liangwu's army finally arrived here.

After Li Liangwu settled in the best inn in the town, Ruan Chengfu took two henchmen to Li Liangwu's residence to ask for a meeting.

As an important general of the navy, Nguyen Chengfu naturally recognized Li Liangwu. After the two met, Nguyen Thanh Phu handed over the order stamped with the king's seal to Li Liangwu, and said that the lord remembered that he had worked hard all the way, and now he was only more than half a month away from the capital, and he could go back to the city with the soldiers on the boat to rest for a few days, so that he could continue to fight later.

There was also Brother Wang's holy decree, and it was the naval army general he knew who came to pick it up in person, Li Liangwu really did not doubt it, and handed over the 100,000 army to one of his most reassuring henchmen to manage, and other generals assisted. Then, happily took 50,000 troops on Nguyen Thanh Phu's warship......

Seven days later, Ruan Chengfu, Pang Wanchun, Qiu Qionghu and others marched into Wrestling City with an army of 50,000 people......

After another three days of differentiation and screening, half of the 50,000 captives were left to join the Song army, and the rest were immediately transported away to reduce the trouble of watching the captives. After two major blood transfusions, Zhao Chongyang's army suddenly grew to 100,000.

At this time, a wonderful strategy popped up in Zhao Chongyang's mind, so he called Zhou Dong, Wu Yong, Shi Wengong, Wu Song, Ruan Chengfu and others, and told them the strategy they had just thought of, so that everyone could make up for it.

After listening to his plan, the people thought it was feasible and added to it. At the same time, Zhou Tong said that it is still necessary to make preparations with both hands, on the one hand, according to the plan, and on the other hand, to prepare for an ambush. Everyone thought that the Metropolitan had a point.

Seven days later, in the evening, General Wu Yuanbing, the acting commander of the Annan Army, arrived at Hongsong Town, 30 miles away from the city of Wrestling, with an army of 100,000 troops.

So, the 100,000-strong army camped in a radius of twenty miles around the town of Red Pine. Since they were about to arrive in the capital, dozens of major generals met at night to go to Hongsong Town to find a larger hotel to stay and drink.

It is a small town, built along the river, with only two gates in the north and south. The generals walked outside the north gate and faced a team of Annam troops, led by Ruan Chengfu, the general of the navy.

"Sure enough, General Wu, you have arrived, and the marshal wants you to work hard all the way, so I will bring someone to meet you in the town. The shop in the town has prepared a banquet for the generals. Ruan Chengfu greeted him warmly.

Wu Yuanbing said: "Then there is General Lao Ruan." But are you not besieged in the city? How can there still be time to greet us? ”

"So that the general learned that on the night of the marshal's return, he went ashore in advance here, and then sent two small soldiers to sneak in through the drainage hole of the Water Gate, and make an appointment with the defenders in the city. Under the personal leadership of the lord of the country, the defenders of the city slaughtered from the gates of the city as promised, killing and wounding more than 30,000 enemy soldiers on the spot, and the remaining remnants of the defeated army fled on ships overnight. ”

"Dashuai is worthy of being the pillar of our Annan, and as soon as he comes back, he will beat the Song people to the ground."

"That's, that's. Otherwise, there are several princes, why did he become a handsome? ”

"Haha......"
