Xiao Yan and Xiao Chen's uncle and nephew did not have a long time to join Chen, but compared with the Southern Chen guards in other places, the attitude of anti-Sui loyalty to the Chen Dynasty was more resolute. The two of them were not stupid, so they ordered someone to find a copy of the edict issued by Yang Jian, the ancestor of the Sui Dynasty, and read it carefully word by word, and found that the Sui Dynasty raised troops to attack Chen, and the most direct and main reason listed was to surrender and accept the rebellion, and in the seventh year of the emperor, he indirectly accepted his uncle and nephew to lead 100,000 Hou Liang clan and the people to abandon Sui Dongtou. This also made Xiao's uncle and nephew worry about their own fate after Sui crossed the river to destroy Chen, so he chose the path of trying his best to prevent the Sui army from destroying Chen.

Because of this, when Chen Junfan, who was instigated by Qinglian, rushed to Wuzhou in person, met Xiao Yan, and proposed to him that the three-city coalition army block the eastward advance of the Sui army, Xiao Yan didn't even send someone to Nanyu Prefecture to inform Xiao Chen, so he made the decision for Xiao Yan and readily agreed to Chen Junfan's request.

After personally accompanying Chen Junfan to Wuzhou and forming an alliance with Xiao's uncle and nephew to reject the Sui, Qinglian rushed to the mountainous areas around Jiangsu and Zhejiang in advance to arrange and deploy military forces, and said goodbye to Chen Junfan on the grounds that Chen Junfan refused to be called emperor and stabilized the rear, and did not know where to go.

After Qinglian left abruptly, when Xiao Yan learned from Chen Junfan that the middle-aged man with a slightly fat figure and a kind face who had been with him was Guan Zizi, the big leader of Nanchen's secret spy agency, Yanchao, he sighed in surprise and couldn't help but complain that Chen Junfan did not keep Qinglian behind, so that he could use the huge hidden power of "Yanchao" to help him when the Sui army attacked the city.

In the face of Xiao Yan's complaints, Chen Junfan could not clearly say to him that he would inherit the mantle of the Chen family, and that he would be the emperor in Jiangsu and Zhejiang one day, and he also counted on Qinglian to rush to his place first, make arrangements for him in advance, and reserve a way to retreat, so he only smiled and did not give any explanation.

Just when Chen Junfan personally went to Wuzhou and formed an anti-Sui alliance with Xiao's uncle and nephew, intending to block the Sui army's eastward advance, Yu Wenshu, the governor of Shouzhou of the Sui Dynasty, had already been ordered by the generalissimo of Chen Bingma and Yang Guang, the king of Jin, to lead 20,000 elite Sui troops to the city of Southern Yuzhou. Almost at the same time, the Sui army led by Luocong Gong Yanrong also appeared outside the eastern city of Wuzhou, planning to launch a fierce attack on Wuzhou.

In a day or two, among the three cities along the river that formed an alliance, only the small city of Jinling, which was garrisoned by Chen Junfan's army, was not attacked by the Sui army. In the face of this situation, Chen Junfan behaved quite righteously, he did not wait for Xiao Yan to open his mouth to help him, that is, he ordered his deputy general to lead the three thousand soldiers and horses stationed in the Jin Tomb to pour out, from the flank of Yan Rong's department to carry out a surprise attack on the Sui army, actually took advantage of Yan Rong's headquarters to cross the river and gain a foothold in a small victory, killed nearly 100 Sui soldiers, and forced Yan Rong's troops to retreat for thirty miles.

As a result, the morale of Xiao Yan's troops in Wuzhou City was greatly boosted, and he actually changed his previous defensive position, intending to cooperate with Chen Junfan's troops from inside and outside, attacking back and forth, and annihilating the Sui army of Yanrong's department in one fell swoop, and did not hesitate to dispatch most of the defenders in Wuzhou City, and launched a fierce counterattack against the Sui army besieging Wuzhou City.

Yan Rong was ordered by Yang Guang to lead 10,000 soldiers and horses in his headquarters, as the East Route Army crossed the river to attack Chen's army on the fourth road, and immediately launched an attack on Wuzhou City after crossing the river in the East China Sea.

Yan Rong has always been wild and uninhibited, even in the north when leading the army against the Turkic iron cavalry has never flinched, this time at the beginning of his army across the river, he has heard that He Ruobi, Han Baohu two troops and horses are attacking from east to west, has captured the capital of the Southern Chen Emperor Jiankang City a few days ago, the heart is already holding back the momentum of winning meritorious service, one did not pay attention, outside the city of Wuzhou on the road of the Nanchen reinforcements rushed to the Jinling, the loss of one hundred and ten soldiers is just that, seeing that the defenders in the city of Wuzhou dare to turn defense into attack, almost the whole army went out of the city, couldn't help but feel angry in his heart, and he didn't order anyone to find out how many soldiers and horses the other party had dispatched, so he directly picked up the lance and mounted the horse, and personally led 3,000 cavalry troops to rush over to meet Xiao Yan's subordinates.

The 3,000 cavalry led by Yan Rong are all Yan Zhao's disciples recruited locally after Yang Guang went out of the town and merged with the state, and over the years with Yan Rong to the east and west, he has repeatedly defeated the Turkic iron cavalry with extremely strong combat power, and today in the face of Xiao Yan's troops who are mainly infantry troops, how can they let go of the opportunity to kill the enemy and make meritorious contributions, and followed Yan Rong to rush into the ranks of the enemy army, indiscriminately, cut down when they meet people, kill them when they meet people, live like a group of hungry wolves broke into the flock, and directly killed the Nanchen army dispatched in Wuzhou City to cry dad and call for mother, Leaving behind the corpses of hundreds of his companions, he retreated into the city in disarray.

Unlike Yan Rong, the eastward army led by Yu Wenshu was first transferred by Xiao Chen to the assassin of Nanyuzhou outside the city of Nanyuzhou, and ordered the defenders to snipe tenaciously in the two fences along the river outside the city. Yu Wenshu personally took his sword into battle, led 3,000 death soldiers to attack more than a dozen times in a row, but never broke through the two barriers, and led the army to the city of Nanyuzhou.

When Yu Wenshu failed to attack repeatedly, he led more than a dozen personal soldiers to personally survey the terrain by the river outside the city of Nanyuzhou, and unexpectedly found a flaw in the formation of the opponent's one city and two gates, and then sent the battalion of the navy army on the night of the same day, with reeds in his mouth, and swam from the bottom of the water to the two gates and the city of South Yuzhou, and set fire to the two gates overnight.

When the enemy defenders in the two fences saw that the camp was on fire in the middle of the night, they hurriedly ordered their sergeants to go to the river to get water to extinguish the fire. Yuwenshu took this opportunity to lead 3,000 cavalry troops, divided into two routes, attacked two gates at night, drove the enemy troops who were busy carrying water to extinguish the fire back to the city of Nanyuzhou, and captured two gates.

Xiao Tan in the city of Nanyuzhou learned the news that the two gates were occupied by the Sui army, and knew that it was difficult to hold Nanyuzhou, so he led the garrison in the city to retreat to Wuzhou, intending to join forces with Xiao Yan and Chen Junfan and defend Wuzhou. Unexpectedly, Xiao Chen led the army to retreat to Wuzhou City, which was still fifty miles away from Wuzhou City, when he suddenly heard the sound of killing on the side of the road, and was rushed out by the Sui army who had been ambushed on both sides of the road in advance and blocked the way.

"Brothers who have withdrawn from the city of Nanyuzhou, you have heard clearly, Wuzhou City has now been captured by the Great Sui army, and we are all generals in the city. What else do you want, quickly put down your weapons and surrender to the Great Sui. ”

In the face of the persuasion of the opposing army, more than half of the soldiers under Xiao Chen's command silently put down their weapons and surrendered to the Sui army.

Seeing this situation, Xiao Tan knew that the general trend had gone, so under the desperate protection of several personal soldiers, he chose another path and fled.

Yan Rong used deception to successfully lure down most of the Nanchen army from Southern Yuzhou, that is, he joined forces with Yuwenshu's troops and surrounded Wuzhou City.

Xiao Yan and Chen Junfan in the city heard that most of the soldiers and horses led by Xiao Chen were persuaded to surrender by the enemy army in the middle of the road, and they suddenly felt like crying without tears. After the two discussed, they also felt that if they were defending a lonely city, they would become prisoners of the Sui army sooner or later, so they also followed Xiao Chen's example and led the personal soldiers around them, quietly opened the city gate, smeared oil on the soles of their feet, and slipped away.
