I transmigrated to ancient times and became a king with a title equal to mine.

Long Bin's letter to Emperor Xiang Lizong of Dongjiang essentially said: "Uncle, we are separated by the river, each fulfilling our duty. This is a blessing for both countries and a good thing for their people. The war instigated by Brother Xiang Yu ultimately ended with your loss of over 100,000 soldiers. I hope you will reconsider, Uncle."

To prevent you from attacking Lishui again, I have dispatched troops with one hundred cannons to occupy the Danyang line. My nephew is terrified of you and has no choice but to resort to this desperate measure. Only by keeping your troops out of the country can I feel at ease. I have no intention of harming anyone, and I hope that your country will not invade again. Otherwise, I swear to fight your army to the death.

Before reading the letter, Emperor Xiang Lizong had already discussed with the Crown Prince that since they could not fight the enemy, the only option was to make peace with the Great Xia.

After reading the letter, the father and son discussed it all night and finally decided to compromise.

Xiang Wuwen said to his father, "We should never send troops again until we have developed cannons."

Xiang Lizong asked, "What should we do if Long Bin's troops refuse to leave Danyang?"

Xiang Wuwen said with a bitter face, "Father, please forgive my disloyal words, but the fault lies with us. Why did my third brother insist on crossing the river to attack the Great Xia? If we hadn't provoked him, would he have been able to cross the river?"

Xiang Lizong was stunned for a long time before saying, "Yu'er was also doing this for the sake of expanding the territory of Dongjiang Kingdom. Let's not mention this matter again."

Xiang Wuwen nodded and said, "Your subject has never liked politics."

"How do you suggest we send Long Bin's men back?" the emperor asked.

"Father, focus on researching cannons. Once the weapons problem is solved, everything will be easy. His troops are isolated and not a threat. I think it's alright to let him stay here for a while longer!"

Xiang Lizong nodded helplessly. He sighed inwardly: Why didn't I have a son like that?

He still wrote back to Long Bin: "My third son, Yu'er, has passed away, and we will not dwell on the past. From now on, Dongjiang is willing to maintain a long-lasting friendship with Daxia. I hope that my nephew will withdraw the Long family army after some time. Otherwise, I will lose face."

Crown Prince Xiang Wuwen ordered Lü Yong to send a message back.

After receiving the mission, Lü Yong detoured to his home in Jiangning, made all the arrangements, and went directly to the Long Family Army at Taizi Mountain.

Song Zhonglin handed over the south bank of the Huai River, which he had seized, to Ma Huaiyuan and Ji Fangkui respectively, and led his troops into the area pre-arranged by Long Bin to hide.

Clear the official road and allow the Henan Army to penetrate deep into the hilly areas of Zhongli County.

Gu Bufan led the Great Xia Yu Nan Army to advance rapidly, and soon crossed the Yellow River and the Huai River.

Seeing his 50,000 troops advance swiftly in five directions, Gu Bufan, standing on the banks of the Huai River, laughed heartily: "If that brat Prince Nan had sent troops to guard the Huai River, how could I have come here so easily?"

Deputy General Shi Laishou flattered, "The Prince of the South is clever. Knowing he can't stop Lord Fan's army, why bother? Besides, he's just the Prince of the South; military power is in the hands of the Marquis of Wanjiang. He can't do anything about it."

Gu Bufan suddenly remembered Li Guixiao.

"Immediately send men to secretly infiltrate Lishui and ask Lord Li to arrest Long Bin. If he causes trouble, you may kill him!"

Gu Bufan had no idea that the Marquis of Wanjiang no longer recognized himself, and that his soldiers had overnight become the personal guards of the King of the South.

What he was even less aware of was that the vanguard of the Southern Henan Army, numbering 10,000, had already been surrounded by Song Zhonglin.

Zong Zhonglin's voice rang out from the tin cannon invented by the Southern King: Brothers of the Southern Army, we are all citizens of the Great Xia. The people of Great Xia do not fight against each other. We must not become tools for the royal family to fight for the throne.

Brothers, many of you have families. If you die here, what will happen to your wives, children, and elderly parents?

After a loudspeaker announcement, several cannon shots rang out, causing an uproar among the troops in southern Henan.

"My god?! What kind of divine weapon did the Southern King's team get?"

"Oh no! We've been struck by lightning as divine retribution!"

Seeing the corpses piled up after a single shell, the morale of the troops collapsed instantly.

"Listen up, commander of the Southern Henan Army! Order your men not to attempt to break out. I'm giving you one hour to consider whether to surrender."

"You're already surrounded by my cannons, or what some people call thunder. You think you can escape? No way."

Vanguard General Gu Dingping, the eldest son of Gu Bufan, had no choice but to send a message by carrier pigeon to his father for help.

The son was surrounded, and several cannon shots blasted down a hundred soldiers.

It was only then that Gu Bufan began to believe the folk legend.

"It seems that the story of Wawa Longbin shelling Xiang Yu is true."

Even a fool knows that the victory of the Prince of Nan at Lishui couldn't be fake; it was just a tool the Empress used to get rid of him.

Since the cannon was so powerful, Gu Bufan felt a little uneasy.

In order to curry favor with the second prince, he brought his two sons and one son-in-law with him on this expedition to Lishui.

In other words, 30,000 of the 50,000 troops in southern Henan were from the Gu family.

Thinking of this, Gu Bufan suddenly felt he had to back down; he couldn't possibly let his own flesh and blood become cannon fodder.

He looked at his third son beside him: "Ding Sheng, quickly save your brother. I will immediately order him to join you in attacking from both inside and outside and break through the encirclement. We will not go to Lishui."

"Father, why don't you have my brother-in-law advance five miles away from me?"

Gu Bufan thought for a moment and nodded, saying, "That's good, to prevent you from getting surrounded as well."

At this point, the old man's heart skipped a beat: Where did Long Bin get his soldiers?

An army capable of surrounding 10,000 men must have at least 20,000 to 30,000 men.

Oh no! He immediately realized that the Marquis of Wanjiang was doomed.

If that's the case, then Long Bin must have taken over Li Guixiao's 60,000-strong army.

Thinking of this, Gu Bufan instructed, "Ding Sheng, finish this quickly. If anything unusual happens, retreat immediately!"

"Father, rest assured, I understand."

Gu Dingsheng and Hua Rushan, the two brothers-in-law, were marching five miles apart.

The tactics that the King of the South taught the monkey were the "encirclement and suppression of reinforcements" strategy of a great man from a previous life.

Now we've surrounded one, but two have come. What do we do?

Several brigadier generals looked at Song Zhonglin.

Song Zhonglin gritted his teeth and said, "Let the reinforcements in front go, but hit the guy in the back."

Half an hour later, the cannons roared, and Hua Rushan's 10,000 men scattered and fled in all directions.

Song Zhonglin hurriedly said, "Use three cannons to fire at the sniper cannons. As long as we keep these 10,000 men in disarray, we can fight again. The rest of you, men and cannons, take down these 10,000 men in the middle!"

When Gu Dingsheng saw his brother-in-law being beaten, his heart skipped a beat. Like father, like son. Gu Bufan was a famous general of the Dog Xia, and his sons were all brave and fierce.

The lieutenant's heart tightened, and he hurriedly said, "General, decide quickly whether to advance or retreat."

"Jin can reunite with my elder brother, but why didn't they beat me? Why did they beat my brother-in-law instead?"

"Not good! Everyone must disperse immediately and break into smaller groups to break out!" Gu Dingsheng said, and he took the lead and ran towards a hillside.

He was quick-witted, but unfortunately he ran into Song Zhonglin, the monkey, and the military strategist of the Southern King.

Just as Gu Busheng's 10,000 men were quickly dispersed, a burst of cannon fire suddenly rang out from the east and west, fireballs flew into the position, sand and gravel flew everywhere, grass and trees flew up, and cries echoed across the land.

Gu Dingsheng turned around and collapsed to the ground, wailing, "Damn Long Yingkun, for your sake in fighting for the throne, you actually lied through your teeth, not only framed the Prince of Nan, but also made our Yu Nan Army cannon fodder? I'll fuck your grandma, you'll die a horrible death!"

After a burst of cursing, he tore off his white robe and wrote in blood: "The might of heavenly thunder cannot be resisted; the Gu family should not become someone else's tool."

After releasing the white doves, Gu Dingsheng fell amidst the gunfire.
