In April, the officials of the Great Song Dynasty sent envoys to recruit Liu Jiyuan and the soldiers defending the city, but the soldiers defending the city refused to even report it, and directly shot him back with a random arrow. Zhao Jiong felt humiliated, and put on armor overnight to urge the generals to attack Taiyuan, day and night. Liu Jiyuan, the lord of the Northern Han Dynasty, mobilized the people in the city to pick up the arrows shot into the city by the Song army, and purchased them for ten cents per arrow, and actually collected millions of arrows. In May, the hearts of the important ministers of the Northern Han Dynasty began to fluctuate, first the Northern Han Xuanhui made Fan Chao claim to go to war, but in fact he tried to surrender and was mistakenly killed by the Song army, and then the Ma army commanded Guo Wanyue to surrender, which was accepted by Zhao Jiong.

Since then, the Northern Han court ministers in the surrender of the discussion bee, only the previous advocate of the surrender of the Song Dynasty Liu Jiyuan's brother, the Jianxiong Army Festival made Liu Jiye insist on not surrendering, Liu Jiye said, if the war is not started, the Han lord Natu surrendered to the Song, it is not a bad policy to protect the people, but the army has been fought for nearly four months, both sides have suffered heavy casualties, once surrendered, although the ministers of the Han clan can be preserved, the possibility of the Kaifeng soldiers slaughtering the city full of hatred in the east of the river is great, so for the sake of the people of the city, when the city is insisted on defending the city, the Song army will run out of money and food, and it will be withdrawn. At most, the jade is burned, and it is better than the big guy who is killed after the disarming and surrendering. Most of the soldiers and civilians in the city agreed with Liu Jiye's statement, but Liu Jiyuan, the lord of the Han Dynasty, was surrounded and lobbied by the ministers who wanted to surrender day and night, and gradually became moved.

The Song army gradually detected some movements in the city and began to consciously strengthen the attack on the southern city wall defended by Liu Jiye, but the Jianxiong army was the best elite soldiers in the north. In order to dispatch elite troops to stop the counter-assault of the Yang cavalry, he has personally stationed himself in the siege hole dug under the city wall for several days, and has been directing the soldiers to attack upwards without sleep. Zhao Jiong was originally supervising the battle in the west of Taiyuan City, which was directly approaching Liu Jiyuan's palace city, and when he heard that the battle in the south was even more tragic and the soldiers suffered heavy casualties, he put on heavy armor and wanted to go to the siege cave to direct the army to attack the city. Cai Hanqiong was shocked when she heard this, and rushed back from under the city wall despite Yashi, crying and advising the officials to take care of the dragon's body, so that Zhao Jiong dispelled this idea.

In the city of Taiyuan, picking up the arrows shot into the city by the Song army, exchanging them for copper coins from the Yamen Xu officials, and then buying some subsistence food has become the normal life of the people in Taiyuan City. After Cai Jiuyan defected to his son, because of the perennial shortage of soldiers in Daibei, Cai Chengxiang, the head of the Jianxiong Army, bought a house for him to live in Taiyuan City, Cai Jiuyan took Juan'er to stay in Taiyuan. The imperial court soldiers pressed the border, the Jianxiong army returned from Daibei to help, and the family was reunited, but Cai Chengxiang was guarding the city wall every day, and the military salary and military rations were not distributed for many days.

At this moment, Cai Laohan and Juan'er were hiding in a dilapidated house on the street without an owner, waiting for Song Jun's arrow rain to sparse out.

After these days of running, Juan'er is no longer too afraid of traveling in an environment like arrows raining down, Cai Jiuyan is also a veteran oil, and he actually deduced the approximate time when Song Jun's arrows ran out based on the experience of the past few months, and took Juan'er out to pick up undamaged arrows at this time.

"Grandpa, why are there so many arrows in the imperial court?" Juan'er waited for a long time, but did not see the rain of arrows sparse out, and couldn't help but look at the people who were picking arrows behind the street houses under the rain of arrows with some envy. Liu Jiyuan's reward for an arrow was ten copper coins, and a thousand copper coins could only be exchanged for a bowl of gruel in today's Taiyuan City.

As soon as she finished speaking, there was a sudden loud noise, Cai Laohan shouted, "Not good", a hundred-pound stone bullet smashed through the roof, and fell to the ground less than half a foot away, smashing the ground into a big crater more than three inches deep. For a while, the house was full of dust and choked people's ears and noses, and Juan'er was so frightened that she stood on the ground and couldn't speak. Cai Jiuyan was afraid that she would be frightened, so he coaxed: "Don't be afraid, where the stone bullet has fallen, God has lit it, and it is rare for a stone to fall again." ”

At this time, there were several screams on the street, it turned out that the arrow rain of the Song army suddenly became dense for some reason, and a few people who picked up arrows couldn't dodge, and they were hit by several arrows, and they couldn't bear the pain but shouted loudly, so that their skills were even more ineffective, and they were repeatedly hit by arrows, and they rolled on the street for a long time and then lost their voice.

Juan'er looked at this scene with trepidation, and finally couldn't help it, and began to cry in a low voice. Cai Jiuyan's mother-in-law died early, pulling Cai Chengxiang is relying on the stick to produce filial piety, the ancient precept that men shed blood without tears, seeing her crying, only sighed, and waited until the Song army's arrows finally thinned out, according to the hour, about a wave of arrows were used up, and when they were waiting for the continuation of the baggage, Cai Jiuyan did not call Juan'er, walked out of the house alone, and carefully selected those arrows that were not damaged. Before long, Cai Laohan felt some noise behind him, and when he looked back, it was Juan'er who also followed, she didn't have the strength to pick up the arrows that shot into the cracks in the bricks and stones and the beams of the house, so she could only look around for the arrows that happened to hit the roof tiles at an oblique angle and bounced off the ground. Seeing that Juan'er still had tears on her face, like a flower-faced cat, but she bit her lip tightly, Cai Laohan sighed again, and reached out to pick up a few arrows that had been inserted into the people who had been shot dead.

On May 6, the fourth year of the Taiping Rejuvenation of the Kingdom, after nearly five months of resistance, the former privy deputy envoy of the Northern Han Dynasty and the left servant shot Ma Feng to carry himself into the palace, crying bitterly and persuading Liu Jiyuan to surrender. Liu Jiyuan, out of the same concern as the Uighur Jingqiong Khan of Hexi, did not consult with the city generals, and sent Xue Wenbao, a messenger, to deliver a letter of surrender to Zhao Jiong that night.

Zhao Jiong was overjoyed when he heard that Liu Jiyuan, the lord of the Han Dynasty, was willing to surrender. At this time, due to the desperate resistance of the soldiers and civilians in Hedong, the casualties of the forbidden army were more numerous, Wang Tingyi, the head of the inner and outer Mabu army, and Shi Hanqing, the commander of the palace in front of the envoy, was seriously injured and died, and among the rest of the generals, Cai Hanqiong, Jing Si, Hu Yanzan, and Han Qi were also seriously injured.

Zhao Jiong immediately went to the north of the city, feasted Xue Wenbao in the city, accepted his surrender, and ordered him to bring an edict to Liu Jiyuan to show comfort and allow him to enjoy wealth and prosperity. Zhao Jiong promised to exempt Liu Jiyuan from his crimes, and gave him a jade belt and 3 gold and silver saddle horses, 500 taels of gold, 5,000 taels of silver, and 2,000 pieces of Jincai. He also appointed Liu Jiyuan as the special advancement, the inspector of the school, and the general of the right guard, and the prince of Pengcheng County, and appointed Cai Yun, the prime minister of the Northern Han Dynasty who had made meritorious efforts to persuade him, as the palace supervisor and Ma Feng as the young government supervisor. In exchange, Liu Jiyuan surrendered the next day, that is, on the morning of May 6, and immediately opened the gates on all sides of the city and allowed the forbidden army to enter the city.
