Although Yang Tongwen had never entered martial arts, he was good at accepting new ideas and admired Wei Sheng who captured Haizhou. Wei Sheng invented the thunderbolt cannon, which was filled with iron cylinders, stuffed with gravel, and placed on the gun truck. In the event of an enemy, it can shoot 200 steps out of gravel and kill and injure the enemy.

Wei Sheng built dozens of artillery carts, which were pushed by two people when marching, and lined up for a week when camping. The enemy is at a distance and is bombarded with artillery; When the enemy approaches, the axe men will fight from the formation. With new firearms, Wei Sheng led his troops to repel Wan Yan Liang's army of 100,000.

Yang Tongwen has done a lot of research on the Haizhou battle case, and has formed his own set of theories in fighting tough battles. When the ancestor Yang Shengtai rebelled and attacked Wenxi Village, he took the lead in using artillery bombardment first, and then infantry attack, and Yang Tongwen carried it forward. Yang Tongwen concentrated all the artillery and opened fire fiercely at the city of Suzhou, and the city wall was blown into gaps everywhere, the city gate was blown to pieces, and debris was scattered everywhere.

How do you cross the moat? You can't fly over, can you? Yang Tongwen was thinking about it again. Suddenly, he thought that the bamboo raft in his hometown could solve this problem. He immediately dispatched a part of his soldiers to quickly cut wood and bamboo in Shangzhong, ordered the craftsmen to tie them side by side, and threw them into the river, as if walking on the ground.

Under the cover of artillery fire, the infantry easily entered the city on bamboo and wooden rafts, and after a fight, occupied the city, and the drawbridge slowly landed on the moat.

Yang Tongwen waved the flag, and tens of thousands of cavalry rushed into the city, followed by the light firearms battalion. Under the heroic fighting of the soldiers, the city was breached in less than an hour.

After the city was broken, Shao Hongyuan's troops, who had been standing still and watching the excitement, entered the battle and cleaned up the mess. Under the attack of the Song army on both roads, the Jin soldiers suffered heavy casualties, and only the defender Moli Mutuo escaped with a small number of Jin soldiers, and Suzhou was recovered.

The conquest of Suzhou greatly encouraged Xiaozong, and he personally wrote to the imperial edict to reward the soldiers: "Recently, the border newspaper, Chinese and foreign encouragement, there has been no such victory in ten years!" He was awarded the title of commander of Li Xianzhong's opening of the palace and the three divisions and the front of the palace, and promoted Li Xianzhong to Huainan, Jingdong, and Hebei to recruit envoys, and controlled all kinds of soldiers and horses. Shao Hongyuan was the deputy envoy, and the position was under Li Xianzhong, so he felt very faceless, and expressed to Zhang Jun that he refused to accept Li Xianzhong's moderation, and the confused Zhang Jun accommodated his request, and Shao Hongyuan was even more unscrupulous.

However, the contradiction between the two generals on the front line tended to intensify, and Li Xianzhong and Shao Hongyuan had serious differences on the issue of the reward of the Suzhou treasury. Shao Hongyuan planned to open a warehouse to reward the soldiers, but Li Xianzhong disagreed, only rewarded the soldiers with cash, and moved the army out of the city. At that time, the army of the Southern Song Dynasty was full of arrogant soldiers, and once they were instigated, people's hearts immediately floated, and the contradiction between Li Xianzhong and Shao Hongyuan became deeper.

On the 14th, Li Xianzhong and Shao Hongyuan joined forces to attack Fu Licheng, Li Xianzhong defeated the Jin army that withdrew from the city to meet the battle, broke through the north gate, beheaded thousands of Jin troops defending the city, and conquered Fu Licheng on the 16th. Li Xianzhong recommended Yang Tongwen to Zhang Jun as the marshal of the capital and took over Shao Hongyuan's soldiers and horses, Zhang Jun thought that Yang Tongwen was still young, so he won a few battles, which was not enough to convince the public, and vetoed Li Xianzhong's suggestion.

On the 18th, Xiaozong's edict ordered Shao Hongyuan to be controlled by Li Xianzhong, because Shao Hongyuan was not satisfied, he changed his order to Shao Hongyuan and Li Xianzhong to divide the headquarters, resulting in the Song army having no commander and fighting separately, which seriously weakened the combat effectiveness. Yang Tongwen was very depressed, he obviously saw Shao Hongyuan's conceit and weakness, but he was helpless, his hope of an exceptional promotion was a trivial matter, Shao Hongyuan was so small-hearted, and if he made mistakes again and again, it would definitely lead to a catastrophe.

As early as after Yang Tongwen conquered Hongxian County, he saw the potential crisis of the Song army, and wrote to the military department, requesting that 50,000 Miao soldiers be quickly mobilized from Shiqian County (Yang Jiajiang Military Base) and put them under his command. Zhang Xuan presented the fold to Song Xiaozong, but he didn't expect Emperor Xiaozong to say: "A little martial champion actually came to command me how to fight, I don't know how the sky is high and the earth is thick!" Yang Tongwen's request was categorically rejected.

After being hit continuously, Yang Tongwen was disheartened, and thought: Without my Yang general, Song Ting wants to restore the Central Plains, so dream of it! The son of heaven of the Zhao family is ten thousand years old, ten thousand hairs! If you don't change the dynasty or the general, without you Emperor Zhao Family, my Yang family general can't live? The east is not bright, the west is bright, and when this battle is over, I have to think about my future.

On the 21st, the Jin general Fushi Lie Zhining led more than 10,000 elite horsemen to counterattack Fuli from Suiyang (now Shangqiu, Henan), Shao Hongyuan wanted to kill Li Xianzhong, and retreated without a fight. Li Xianzhong fought alone and repelled it. The next day, the Jin army added tens of thousands of troops to attack Li Xianzhong's troops, and Li Xianzhong asked Shao Hongyuan to send troops to attack together.

Shao Hongyuan has always been obsessed with the reward, deliberately did not move, wandered in the city, and spread gossip, saying cool words: "On this hot day, it is not cool to shake a fan, let alone fight hard under the big sun!"

As a result, the atmosphere in the Song camp inside and outside the city was dull, the discipline was lax, and the morale of the army was shaken, which was not a good sign!

Li Xianzhong outside the city fought alone, Yang Tongwen led his pro-army and cavalry to attack back and forth, and killed more than 5,000 gold soldiers.

Soon, the main force of the Jin army of 100,000 arrived and launched a fierce attack on the Song army, the enemy was outnumbered, and the artillery was without shells, so it had to fight in close combat. Li Xianzhong's troops, which had no advantage in artillery fire, were defeated and had no choice but to retreat into the city. The Jin army continued to increase its forces and attacked the city again, and Li Xianzhong ordered the Song army to shoot back the Jin army with a strong bow. The Jin soldiers left behind countless corpses and retreated into the woods outside the city.

That night, Zhou Hong, the commander of the Jiankang Chinese Army, beat the drum and shouted for the Jin soldiers to attack, and then fled with Shao Hongyuan's son Shao Shixiong, the commander of the Sima Army in front of the palace, Zuo Shiyuan, and the commander Li Yanfu.

Seeing the discord between Li Xianzhong and Shao Hongyuan, Zhang Xuntong and Zhang Shiyan, the commander of the Ma Military Division, the commander of Chizhou and Zhang Yuan, the commander of Jiankang Mansion, saw that Li Xianzhong and Shao Hongyuan were not in harmony, and they also led their troops to flee, and the Song army collapsed without a fight.

On the 23rd, the Jin army took advantage of the situation to attack the city, and Li Xianzhong led his troops to kill more than 2,000 enemies, and finally it was difficult to prevent the Song army from being defeated.

Shao Hongyuan was afraid of the war and wanted to flee, and Li Xianzhong was afraid that it would be difficult to defend alone, and sighed: "God doesn't want to calm the Central Plains? Why bother to thwart this!" So under the cover of night, Li Xianzhong also led his troops to retreat, and before he could go far, the rumored Song army collapsed on the whole line, and the military equipment was lost on the way to retreat.

On the 24th, the Jin army found that the city of Suzhou had become an empty city, and pursued it, and the Song army was defeated, with more than 4,000 people beheaded and countless people drowned. The Jin army, which did not know the details, also suffered heavy casualties and did not rush to pursue, and the Song army gained a foothold on the front line of the Huai River.

Suzhou governs Fuli County, so the history of the war is called "the battle of Fuli". More than 100,000 Song troops were defeated in Fuli and fled back to the Huaishui area in embarrassment, dealing a heavy blow to Song Xiaozong's ambitions. He began to vacillate between war and peace, and demoted Zhang Jun to the Jianghuai Xuanfu envoy, supervising the Lianghuai defense line to resist the Jin army's southward advance.

In June, Xiaozong asked the lord and sent a representative Tang Siwei to make a comeback, and in July he made him the right minister. At the same time, the ministers of the main battle faction, Zhang Tao, Xin Ciying, Wang Shipeng, etc., successively went out of the court. In August, Zhang Jundu was reinstated as the governor of Jianghuai's military horses, and adopted Tang Sihui's suggestion to send Lu Zhongxian, an envoy from Huaixi to the Jin army camp to negotiate peace.

In November, Lu Zhongxian brought peace conditions from the Jin State: the Song Emperor and the Jin Emperor changed the relationship between uncle and nephew, the Song Dynasty returned the four prefectures of Hai, Si, Tang, and Deng that were preparing for war, returned the Jin people who had surrendered to the Song Dynasty, and made up for the New Year's coins since the end of Shaoxing (due to the southern invasion of Hailing, the Southern Song Dynasty stopped the New Year's coins to Jin).

The Southern Song Dynasty had a fierce debate about the war and peace, and finally Xiaozong decided to continue the peace. In December, Chen Bokang resigned due to illness, Tang Si retired to the left minister, and Zhang Jun was the right minister.

In the first month of the second year of Longxing, the Jin Dynasty sent another letter, but the asking price was too high and the tone was too big. The right servant shot Zhang Jun to oppose the peace, and asked to move the capital to Jiankang, in order to enter the army, Xiaozong played the quasi-performance, and passed the edict to stop the peace. At the instigation of the main battle faction, Xiaozong removed Lu Zhongxian from the list of unauthorized permission to the four states, arranged Chenzhou, and sent Hu Fang to envoy Jin Ying, threatening that the Song Dynasty refused to return the four states, and the peace talks reached a deadlock.

Xiaozong ordered Zhang Jun to inspect the two Huai, prepare for war with all his might, and prepare to fight with the Jin army. Tang Siwei was deeply uneasy, and he argued vigorously, rejecting Zhang Jun, the main battle faction, and entangled the party to attack Zhang Jun "in the name of garrison, but not necessary for defense, and in the name of governing soldiers, and the soldiers may not be fine." The unassertive Xiaozong urgently summoned Zhang Jun to the court in April and removed him from the post of right minister. Four months later, Zhang Jun died on the way out of Beijing, and Xiaozong completely fell to the side of the Lord and the faction.

In June, Xiaozong ordered Hu Beijing to make Yu Yunwen abandon Tang and Deng Prefectures, but Yu Yunwen refused to carry it out, so he was removed from his post and demoted to Pingjiang Prefecture. In July, the Song army in Hai and Sizhou retreated. In September, Xiaozong ordered Tang Si to retire from the Jianghuai military horse, and Yang Cunzhong (that is, Yang Yizhong, who was given the name Cunzhong by Song Gaozong) assisted Tang Siwei, who knew nothing about military affairs, as the deputy governor.

Who is Tang Siwei? Qin Huizhi's fellow party also, he secretly communicated with the Jin people and asked the Jin army to force peace. In October, the Jin State sent troops to invade the south again, and Wulu sent his servants to disperse Zhongyi's army to the south, easily breaking through the unprepared Song army's Lianghuai defense line.

In November, Chuzhou, Haozhou, and Chuzhou were lost one after another, and the Yangtze River defense line was once again in an emergency. Tang Siwei advocated abandoning the two Huai, retreating to the Yangtze River, and negotiating peace with Jin as soon as possible.

At this time, Xiaozong heard that the Jin people were talking about the price of peace, so he said angrily: "If you want to kill the country, you will not submit to it." The ministers of the DPRK and China were indignant and condemned Tang Si's crime of withdrawing troops to negotiate peace. The Southern Song Dynasty's anti-Jin call rose again.

In November, Xiaozong dismissed Tang Siwei and relegated him to live in Yongzhou. Seventy-two people, including Zhang Guan, a student of Tai, asked Tang Sihui and his fellow party Wang Zhiwang to behead him, and Tang Siwei heard the news on the way to the debasement and died of shock.

Chen Bokang was once again appointed as the left minister to preside over the overall situation. However, the Song army was repeatedly at a disadvantage, and Xiaozong, who was not strong on the battlefield, had to send Wang Tuan as an envoy to negotiate peace with the servants.

Seeing that the goal of forcing peace by war had been basically achieved, Emperor Wulu of the Jin State stopped the offensive and resumed the negotiation of peace.
