The ancient continent is divided into five regions: east, west, north, south, and middle. The regions are separated by the sea. Among them, there are large countries such as Qi, Chu, Zhou, and Han in the northern region.

In the eighteenth year of Qi Taihe, in the hall of Qi Heng, Emperor Zhang Muhan of Qi and Emperor Zhang Muhan bowed his head and pondered. "Report, 800 miles of weir pass urgently", a soldier crossed the main palace gate, hurriedly rushed to Qi Heng Palace, arrived at the outside of the hall under the steps, the guard took the document and quickly went up more than 100 steps to the outside of the palace gate, the inner supervisor was already waiting outside the hall. Obtaining the paperwork, he hurried to the temple. "Your Majesty", the inner supervisor bowed his head, held the document with both hands and handed it to the emperor. "The weir pass guards Zhao Yongcheng and His Majesty the Emperor, the Chu army raided the weir pass, menacing, no less than 100,000 soldiers and soldiers of the Yanguan Pass, has lost 4,000, although the weir pass is dangerous to defend, but the Chu army is overwhelming, I hope Your Majesty will quickly send reinforcements. The weir guard general Zhao Yong. Emperor He's face was slightly pale, "Liu Sheng, Yuan Zhan, the Minister of Military Aircraft, and others met with him", "The old slave commanded."

The screen pans to another place. In the Xiangwang Mansion, there was a tense atmosphere. Princess Xiang was about to give birth, and Zhang Deyuan, the king of Xiang, was very anxious and walked back and forth outside the house. It's noon, and the sun is exposed. After a while, there was a sound of joy in the house, accompanied by a baby cry. The big stone in King Xiang's heart finally fell. Hurriedly rushed into the house, came to the bedside, held Princess Xiang's hand tightly, and put it on his face. "Thank you, Cher". King Xiang wept with joy. "Husband, where is the child?" An old mother gently holds the baby to the princess. The princess kissed the child's forehead and turned to the prince. "Husband, let's choose a name for the child." King Xiang looked at the child and thought for a while. "It's called Zhengfeng! I hope he is a decent person, sharp, sharp, sharp, and I hope he will be an excellent person in the future. is also the son of the emperor's brother, Zhang Zhengyan. "Well, okay, it's called Zhengfeng." King Xiang motioned to the old mother to take the child away. "Cher, you have a good rest." "Hmm." Seeing that Princess Xiang was resting, King Xiang withdrew from the house.

In the hall of Qi Heng, he discussed with the emperor and a group of military ministers how to deal with the urgency of the weir pass. Emperor He carefully observed the demeanor of the various military ministers, but he found nothing. The old minister Yuan Zhan said: "Your Majesty, the weir pass is the southern barrier of the empire, once it is lost, the imperial capital is in danger." Now we can transfer 30,000 reinforcements from the Longnan Military Region, this time the Chu army raided the Yanguan, why, and whether there is a bigger conspiracy behind us, we have no way of knowing, so we can only do it first. He Diyun ordered the commander of the Longnan Army to make Chen Jun do this quickly.

"Runchen, quickly send Qianlingwei to secretly follow up on this group of military ministers, don't let go of any details, and report to me as soon as possible." "Yes, Your Majesty". Zhang Runchen is the commander of Qianlingwei and the son of Emperor He. Qianlingwei's main job is to secretly protect the emperor and collect intelligence. As for why the Chu army raided the Yanguan, only Emperor He himself knew it.

More than 1,000 years ago, Qi and Chu were great powers in the Northern Regions. But thirty years ago, Emperor Chong of Qi Zhang Wu was mediocre and caused the decline of the Qi State, and after the First World War of Qi Chu and Jingxiang, the Qi State was even more depressed, and Jingxiang was occupied by Chu. Later, Liu Qing built the Southern Han Dynasty, Song Yi built the Northern Wei Dynasty, Liuji Town built Dongwu, and Ma Ying built the Western Shu, all of which were established by occupying Qi territory. The external territory of Qi was fragmented, and after the emperor and the throne, he tried to improve and achieved certain results, especially after the Qi general Tie Xiao thwarted the attacks of Liu, Song, Liu, and Ma, and Qi achieved temporary stability.

In the hall of Qi Heng, Liu Sheng said, "Your Majesty, the Xiangwang Mansion sent someone to report that Princess Xiang successfully gave birth to a little prince, and the King of Xiang named Zhengfeng, so he sent someone to report the good news." "I know, send someone to send some supplements to King Xiang's mansion, so that Princess Xiang can take good care of her body." Zhang Deyuan, the king of Xiang, is the fourth son of Emperor He, who has both civil and military skills, and is valued by Emperor He. He was born with Emperor Lifei, who died shortly after giving birth to Zhang Deyuan, and Emperor He handed Zhang Deyuan over to the queen to raise. The queen's eldest son, Zhang Deyao, is the crown prince and has always excluded Zhang Deyuan. Zhang Deyuan thought of his mother's kindness and didn't care about it. Zhang Deyao is not as talented as Zhang Deyuan, but because Zhang Deyao is the eldest son, he sits on the throne of the prince.

In the sixteenth year of Taihe, Zhang Deyuan fought in the Fuling area and met the minority Mangzhen female Descher. The Mangzhen tribe, one of the few ethnic minorities in Qi State, all have the surname Dishi. Mang Zhen has always produced beautiful women. Descher is a great beauty. Zhang Deyuan married him soon after. Now, Princess Xiang has given birth to a son. Zhang Deyao also has a son Zhengyan, so Zhang Zhengfeng's birth threatens Zhang Deyuan.

In fact, Emperor He's twelve sons, Zhang Deyuan's second brother, third brother and seventh brother all died on the battlefield. The second brother has two sons, and the third brother has no children, so Zhang Zhengfeng is also the fourth. In the early years, Emperor He passed Zhang Deying's second son to Zhang Deyuan's third brother Zhang Deyong, so that he would not have a successor. Zhang Zhengfeng also became attached to the fourth.

In the southern border of the Qi State, Jingxiang and Yanguan were all important barriers to the south of the Qi Empire. Jingxiang is built on the Li River, although it is located at the junction of Qi and Chu, it is prosperous and abnormal, mainly because of the developed water transportation. For thousands of years, major commercial ships must stop when they arrive in Jingxiang, so Jingxiang has the reputation of the world's commercial capital. There's all sorts of weird stuff here. One side of it is close to water, three sides are empty, and a hundred miles behind it is the weir pass. The city wall of Jingxiang is tall, there is the Li River as the screen in front, and there is a weir pass in the back, so it is easy to defend and difficult to attack, but decades ago, because of the negligence of the Jingxiang guard, the Chu army attacked at night, resulting in the fall of Jingxiang, and the later Qi country gathered heavy troops and Chu fought fiercely in front of the weir pass, Qi was defeated, and then Chu occupied Jingxiang so far.

In the city, the prosperity is still the same, people seem to have forgotten the pain of the war, in fact, Chu Zhan Jingxiang did not use cruel officials, but to appease, after all, Jingxiang is an important town, and the economy is developed, and more than half of the residents from other places, if the implementation of the policy of driving out the local people, colonizing the Chu people, it will definitely cause dissatisfaction in other countries.

Four hundred miles below Jingxiang is today's Southern Han, after Liu Qing built the Southern Han, he further consolidated his power, but the Southern Han was sandwiched between Qi and Chu, and the terrain was not good. And there are many people in the city, and if there is a slight difference, the Southern Han will collapse.

The scene shifts to Jingxiang City, where Ah Hao (Yang Zhihao) wanders the streets, occasionally fiddling with slingshots from toy stalls and occasionally looking at seasonal fresh fruits. Ah Hao is a local resident of Jingxiang, grew up drinking water from the Li River, and is now eighteen years old, but because his family is poor, he has not yet married a daughter-in-law, but he has had great ambitions since he was a child, and he wants to be a useful person to the country. As time passed, he also grew up slowly, and he also knew that his country was in decline, and he was living under the rule of the Chu State, and he secretly swore that he would personally drive out these Chu troops in the future.

Suddenly, another teenager collided with him, this person's name was Li Fan, who was about the same age as Ah Hao. Before Ah Hao could speak, Li Fan scolded, "You don't have long eyes when you walk." "Levan is very arrogant. Ah Hao was so angry in his heart, it was obvious that he bumped into me, so if he didn't apologize, he would forget it, but the wicked person sued first. Ah Hao raised his fist without saying a word, and the two fought. It's really not a fight, you don't know each other. A quarter of an hour later, the two were still deadlocked. "Stop, stop, don't fight, brother, you're good, how about making friends." Levan said. Ah Hao was also a little tired, so he stopped, holding back the anger in his heart, "Under Yang Zhihao, dare to ask what Brother Tai is called." "In Xia Lifan, I offended just now, why don't I invite you to drink, as if it is to make amends, how about it." Seeing that he was making amends, Ah Hao put aside his prejudices and readily agreed, "Very good, please." The two came to a restaurant and drank heartily, during which the two talked about their life ideals. "My parents died when I was young, and my grandfather died when I was 10 years old. My parents died under the sword of the Chu people, and I must avenge my parents. I plan to leave Jingxiang in the near future and go to Suzhou, our country, to break through. Ah Hao listened, "Brother, I also have this intention, today we will say goodbye for the time being, when I go home to tell my parents, ten days later, we will set off together." "Good". The two said goodbye.

In the sky of the imperial capital in the distance, a cloud was shrouded, and it seemed that something big was about to happen.
