On the first day of June, it rained heavily in the sky, and it was the height of summer again.

The heat in the air was swept away by the heavy rain, and the water curtain was connected to the sky and the earth, and a large amount of rain poured down, and the sound of rain alternated far and near, covering all the noise between heaven and earth.

Wang Bo, the king of the Tang Dynasty, wore armor and walked on the head of the county seat. Raindrops hit the nail leaves with a "popping" sound.

Song Shilun was in the gate tower of the north city of Dai County at this time, looking at the map seriously. The location of the Yongjun army at this time was clearly marked with a red line on the map, and the Youjun army was less than sixty miles away from Dai County.

"Wow—whoa—"

Hearing the sound of wading footsteps, Song Shilun raised his head and saw Wang Bo walking in, with a series of footprints with water behind him.

"Any news from the scouts?"

Wang Bo entered the house, and he didn't even bother to take off his armor, so he asked.

Song Shilun nodded and said, "The news just came back that the front of the Youjun army has been divided into three groups, which are the two camps outside the city and the county seat."

Wang Bo heard this, and snorted coldly: "This prince of Youguo really wants to be beautiful, and with a lot of people, he wants to come to a full flower? and not afraid to shatter his teeth."

Song Shilun smiled and said, "But in fact, there are a lot of people in the Youjun."

Wang Bo wiped the rain from his face and said, "This rain is really timely, herald!"

"Here!"

"Give the order to everyone to take a break from the city to stand guard! Prevent the sneak attack of the Hidden Army!"

"Whoa!"

Wang Bo did not dare to despise the enemy, such a rainy day was very suitable for the attacker.

In the Wubei Academy, the most classic case that Wang Bo learned was that Li Tang's famous general Li Yuxue entered Caizhou at night.

In the eighth month of the ninth year of Li Tang Xianzong's Yuanhe, the Zhangyi Army (Huaixi) Jiedu made Wu Shaoyang die, and his son Wu Yuanji hid and did not mourn, forged Wu Shaoyang to appear in the Li Tang court, claiming to be seriously ill, and asked his son Wu Yuanji to stay behind. The Li Tang court did not allow it, and Wu Yuanji took over the military affairs by himself, and supported the army to rebel against Li Tang. Send troops to burn Wuyang and Yexian, and capture Lushan, Xiangcheng and Yangzhai.

The Zhangyi Army (Huaixi) Jiedu envoy was stationed in Ruyang, Caizhou, located in the Central Plains, with an important strategic position. Since Lee Hee-yeol, he has remained semi-independent. However, Huaixi was surrounded by prefectures and counties under the jurisdiction of the Li Tang court, and Li Tang Xianzong had the capital to crusade against Huaixi, and only by bringing Huaixi, a separatist force, into the sphere of influence of the Li Tang court, could he attack the largest feudal force that was almost independent of the Li Tang court, the Hebei feudal town force.

Initially, Li Tang Xianzong sent Li Guangyan, Li Wentong, Yan Shou, Li Ting and other generals to lead Xuanwu and other 16 armies to fight against Wu Yuanji in Huaixi, and there were mutual victories and defeats, but they failed to shake the foundation of the Huaixi army, and the war entered a tug-of-war.

At the same time, the local Jiedu envoys, led by the Hebei feudal towns, ostensibly supported the crusade of the Li Tang court. But secretly colluded with Wu Yuanji to support and assist.

In particular, Pinglu and Ziqing Jiedu made Li Shidao the most arrogant, and after dissuading the Li Tang court from crusading against Wu Yuanji unsuccessfully, he actually sent someone to assassinate Wu Yuanheng, the prime minister of the auditorium court who was advocating the crusade against Huaixi, and sent people to secretly infiltrate the Heyin Cao Courtyard and burned more than 300,000 horses and more than 30,000 grains of the Li Tang court.

The crusade against Huaixi was unsuccessful for four years, and the financial expenses of the Li and Tang courts were also very serious, at this time internal disputes began to appear, and the main peace faction began to rise. Tang Xianzong chose to persevere, and in view of the unfavorable situation of the war, he made several changes: first, he canceled the crusade against Wang Chengzong, the envoy of Chengde Jiedu, and concentrated his forces to deal with Wu Yuanji in Huaixi; the second is to recall the eunuchs who went to the front line to supervise the war, and resent Pei Du to Huaixi to supervise the war; The third is to send Li Yu to serve as the military commander of the Wu front.

Li Yu is the son of Li Sheng, a famous general in the Tang Dynasty, known for his filial piety, and has served in the Li Tang court for a long time, and has not had many military exploits.

Li Yu was also quite low-key, and when he arrived at the front, he said to the soldiers, "The saint sent me here because he knew that I had a gentle personality, and sent me to appease everyone. As for fighting, it's not my specialty or purpose."

At this time, the officers and soldiers who had been fighting abroad for four years were very war-weary, and the arrival of Li Yu reassured everyone that there were such moderate generals

At least in the short term, there will be no major offensive against Huaixi.

Wu Yuanji also breathed a sigh of relief, there were no more famous generals, a rookie came, he could also take a breath, and the Huaixi Army gradually relaxed its vigilance.

Li Yu went to the camp in the army, shared weal and woe with the soldiers, mingled, and soon won the love of the soldiers. They found that the new Lord was not too cold and very humane. The morale and combat effectiveness of the army have been stabilized and restored unconsciously.

After the officers and troops regained their combat effectiveness, Li Yu began to harass Wu Yuanji on a small scale without revealing the mountains and inconspicuousness. Every time an army is sent, the main purpose is not to occupy the city and plunder the wall, but to ask for someone - Wu Yuanji's people.

Li Yu first captured Ding Shiliang, a general under Wu Yuanji, alive, treated Ding Shiliang with sincerity and invited him as a guest, and finally Ding Shiliang surrendered sincerely.

According to Ding Shiliang's suggestion, Li Yu made a surprise surprise to capture Wu Xiulin and Li You, the generals under Wu Yuanji, especially Li You, who was the first fierce general under Wu Yuanji.

Li You's recruitment of Li You caused a lot of controversy among the officers and soldiers, because in the four-year war of attacking Huai, Li You killed many soldiers of the official army. There was a loud call within the official army for Li You's killing.

But Li Yu still tried his best to resist public opinion, not only surrendered Li You, but also entrusted him with important tasks, and sent people to protect Li You's personal safety.

Wu Yuanji found that the three fierce generals around him were accidentally poached, and he realized that the opponent he was facing was not easy to deal with.

At the same time, the Li Tang court stopped the use of troops against Wang Chengzong, the envoy of Chengde Jiedu, and began to form a siege of Wu Yuanji. Li Tang and Li Guangyan's troops defeated the Huaixi Wu army at Yuncheng and destroyed 30,000 enemies. When Wu Yuanji learned of the loss of Yuncheng, he panicked and transferred all his troops and the defenders of Caizhou to the northern front to reinforce Dong Chongji's defense.

In September of the thirteenth year of Yuanhe, Li You saw that the conditions for a surprise attack were ripe, and said to Li Yujin: The elite soldiers of Huaixi are all in Huiqu and the border, and the guards of Caizhou are all old and weak, so they can take advantage of the situation to smash the city and capture Wu Yuanji in one fell swoop.

After fully understanding the military situation and the comparison of forces between the enemy and us, Li Yu thought it was true, and sent people to Yuncheng to secretly present the surprise attack plan to Pei Du. Pei Du was very appreciative and agreed to send troops.

On the tenth day of October in the winter of the eleventh year of Yuanhe, the wind and snow were blowing, and the rebels relaxed their vigilance. Li Yu took advantage of the weather conducive to the surprise attack, ordered Shi Min to stay in Wencheng, ordered Li You and Li Zhongyi to lead a well-trained death squad of 3,000 people as the vanguard, himself and the prison army to take 3,000 people as the middle army, and ordered Li Jincheng and other generals to have 3,000 people in the rear.

The movements of the army were very secretive, except for a few generals, the whole army did not know the destination of the march and the tasks of the troops, and Li Yu only gave the order to the east.

At night on October 10 in the winter of the 11th year of Yuanhe, after traveling 30 miles east, Li Yu's army arrived at Zhangchai Village, and the defenders were unprepared, and completely annihilated the defenders, including the soldiers in charge of Fengsui alarm, and occupied the outpost of Wu Yuanji Caizhou.

After the whole army had rested and eaten for a while, Li Yu left 500 men to guard Zhangchai Village to guard against the enemy in the direction of Langshan, and Ding Shiliang led 500 men to cut off the bridges leading to Huiqu and other directions to Caizhou, and then ordered the whole army to advance in the wind and snow overnight.

The generals asked where the army was going, and at this time, Li Yu announced that the purpose of this trip: to enter Caizhou and capture Wu Yuanji alive!

The generals were shocked when they heard this, and shouted that Li Yu had fallen for Li You. However, the military order was like a mountain, and there was no turning back from the bow, and the army braved the wind and snow overnight to rush to Caizhou in the southeast.

At this time, the night was cold, the wind and snow were blowing, the flag was broken, and the people and horses froze to death looked at each other. The road east of Zhangchai Village was unknown to no one in the army, and everyone thought that they would definitely die, but everyone was afraid of Li Yu, and no one dared to disobey the order. In the middle of the night, the snow became heavier and heavier, and the army of 8,000 people unconsciously forced a march of thirty-five miles, and finally arrived in Caizhou.

Near the city wall of Caizhou, there was a chicken and duck pond, and Li Yu ordered his soldiers to disturb the chickens and ducks to hide the sound of the march. Since Wu Shaocheng resisted the court's orders, the official army has not arrived in Caizhou for more than 30 years, so the people of Caizhou are unguarded and have not discovered the actions of the official army.

At this time, it snowed heavily in Caizhou City, and the winter night seemed so cold and quiet. Wu Yuanji lives indoors, but it is a different world.

In front of the screen, charcoal burned uncontrollably in the iron basin, reflecting the whole room.

Behind the screen, after a cloud and rain with the concubine

Wu Yuanji fell asleep soundly with his young and enthusiastic body in his arms.

The successive defeats in the Huaixi War could not prevent Wu Yuanji from gaining a moment of comfort and rest on this quiet winter night.

During the fourth watch, Li Yu's army arrived at the city of Caizhou, but the defenders of the city still did not notice. Li You and Li Zhongyi dug the earth on the city wall as a barrier, took the lead, climbed to the top of the outer city, killed the sleeping guards, and left only the night watchmen, so that they could hit the guard as usual, so as not to alarm the enemy.

Now that Li You and the others have succeeded, they opened the city gate to welcome the officials and soldiers. Then, according to the law, they attacked the inner city. When the rooster crowed, the wind and snow gradually stopped, and Li Yu entered Wu Yuanji's outer house.

At this time, someone noticed that the situation was different, and hurriedly came to the door of Wu Yuanji's house, shouting, "General, the big thing is not good, Li Yu has entered Caizhou City."

The soldiers rushed in in a panic, breaking Wu Yuanji's dream.

"Nonsense, Li Yu is still in Wencheng a hundred miles away, it must be a hungry prisoner who ran out to steal things, and kill all those hooligans tomorrow." Wu Yuanji was very unhappy, he didn't get up in the bed, and continued to look for his sweet dream.

The visitor shouted, "General, not a prisoner, but an official army, the outer city has been lost."

Wu Yuanji still didn't believe it, and angrily reprimanded: "Nonsense, it's the soldiers who came back to ask for food!"

The soldiers were helpless, so they had to confirm to Wu Yuanji: "General, it is really the official army, Li Yu's troops!"

Wu Yuanji got up in a rage and came to the inner city tower in his clothes, when he saw thousands of officers and soldiers shouting, "Capture Wu Yuanji alive!" Capture Wu Yuanji alive!"

Wu Yuanji's heart suddenly cooled, and he exclaimed, "Where is this Li Changshi, this is the arrival of the heavenly soldiers!"

On a snowy winter night, Wu Yuanji's most feared opponent in his life, Li Yu, came to his side silently.

But fear is fear, Wu Yuanji still led his followers to resist the official army.

After Li Yu entered the city, he sent people to attack Yacheng on the one hand, and on the other hand, he comforted the family of Dong Chongzhen, the general of Huaixi in Huiqu, and sent Dong Chongzhen's son to surrender. Dong Chongzhi rode alone to surrender in front of Li Yu's army, and Wu Yuanji lost the hope of returning to the defenders of Huiqu.

On the 12th, the official army attacked Yacheng again, and the people of Caizhou rushed to bear firewood and grass to help the official army burn the south gate of Yacheng. At dusk, the city gate collapsed, and Wu Yuanji saw that the general situation had gone, so he had to surrender. More than 20,000 soldiers from Shen, Guang and Zhuzhen also surrendered to Tang one after another, and Huaixi was peaceful.

Wang Bo remembered this example, and wondered if there was any mistake in defending the city, this is a scout dressed in the rain and came in to report: "Acting king, there is new news from the north."

Wang Bo instantly became nervous, and hurriedly asked, "What's the news?"

The scout looked at Wang Bo and Song Shilun and said, "The advance of the Youjun army has arrived ten miles outside the city, and they are stopping to rest the whole army."

Wang Bo directly ordered: "Let people closely monitor the movements of the hidden army, and if the enemy army has any abnormal movements, come and report it quickly."

The scout nodded, and exited in the rain.
