A few days later, Chi Heng led the delegation back to Nanzhou, and after meeting the four princes, the four princes were overjoyed and ordered to reward Chi Heng.

However, the advisers around the four princes were quite worried, and the advice was fraudulent, which was a matter of life and death, and the four princes also wanted to order someone to reconfirm.

However, at this time, the Seven Princes suddenly attacked Huiyang City violently, and the Four Princes could only temporarily put aside the confirmation and concentrate on dealing with the Seven Princes.

The four princes overlooked the siege army of the Seven Princes, but there was no Beiyuan cavalry, the four princes ordered people to pay close attention to the movements of the 200,000 cavalry in the Beiyuan, and ordered the soldiers of Tiexiong Pass to step up the city defense in case the Beiyuan cavalry attacked the city, but the spies of Tiexiong Pass replied, the 200,000 cavalry of Beiyuan not only did not attack Tiexiong Pass, but gradually retreated, close to Qin Shangguan of the Seven Princes, and the soldiers guarding the city of Qin Shangguan seemed to have begun to be on guard.

The suspicion of the four princes towards Beiyuan weakened a little, but under the persuasion of the ministers, the four princes were still cautious and did not dare to rashly transfer the troops of Tiexiong Pass.

After three days of fighting, both sides lost a lot of men and horses, and the fourth prince got a secret letter, in which the seventh prince said that the seventh prince ordered the Beiyuan 200,000 cavalry to attack Tiexiong Pass several times, but the commander of the Beiyuan cavalry was unmoved, and also angrily reprimanded the seventh prince in the reply.

Seven or eight Chinese update the fastest ~ computer: / On the second day, the seventh prince gathered an army of 100,000 to attack the east gate of Huiyang City, but the 200,000 cavalry of the northern abyss suddenly turned around and attacked Qin Shangguan, the fourth prince was surprised when he learned about it, and the strength of the seventh prince's siege was also suddenly reduced, and the fourth prince ordered the transfer of 100,000 defenders of Tiexiongguan to support Huiyang City, and launched a large-scale counterattack, forcing the army of the seventh prince to retreat from Jingyang City, and defending as an attack.

The 100,000 troops of Tiexiong Pass joined the siege echelon, Jingyang City became more and more dangerous, the Seven Princes did not have 200,000 cavalry in Beiyuan, and they lost a lot of troops in the attack.

The 200,000 cavalry of the Beiyuan suddenly turned to attack the Tiexiong Pass, the defenders of the Tiexiong Pass were insufficient, in the face of the mighty 200,000 Beiyuan Iron Cavalry and the defenders of Qin Shangguan, when the military information reached the ears of the four princes, the Tiexiong Pass had been broken, and the four princes immediately ordered the army to retreat, and divided the troops to recapture the Tiexiong Pass.

However, 200,000 Beiyuan cavalry into Tiexiong Pass is not comfortable, the four princes in case of accidents, the entire Tiexiong Pass of the people into only bite and gnaw the spirit corpse, the Beiyuan cavalry has never seen such a strange scene, not afraid of the army into the city, even more not afraid of knives and axes, crazy biting Beiyuan's war horses and cavalry, Beiyuan cavalry panicked, resulting in the easy to break through Tiexiong Pass, enter Tiexiong Pass and the people in the pass are entangled and killed, entangled footsteps.

The strength of the Seven Princes is not as good as the Four Princes, and the Four Princes fight, in less than an hour, the loss of troops is more than 1,000 people, looking at the surging soldiers of the Four Princes, the Seven Princes frowned, and shouted: "Where are the 200,000 cavalry of Beiyuan?" The subordinate replied: "The cavalry of Beiyuan has broken through the Tiexiong Pass, and now they are on the way to a roundabout, and they will soon launch an attack on Huiyang City!" The Seven Princes smashed the table with a sword and shouted angrily:" Soon, you open your dog's eyes and see, the enemy army is strong, our army is weak, and if you continue to fight like this, the enemy army will enter Jingyang City!" The subordinates knelt down in fear and did not dare to say more, the Seventh Prince said: "Where is the Praetorian Guard?" The general of the Praetorian Guard stepped forward and said, "Weichen is here!" The Seventh Prince helped up the general of the Praetorian Guard, and said in a serious voice: "Life and death all depend on the general! We must hold it, and as soon as the 200,000 cavalry of Beiyuan arrive, the victory will be ours!" The general of the Praetorian Guard bowed down and said: "I will not dishonor my life!" Put on the armor, pick up the knife and go, a group of golden army came out majestic, like a bamboo, into the army of the four princes, the name of the Praetorian Guard in the Nanzhou army is famous, the army of the four princes saw this army instantly lost most of the morale, the formation was chaotic, the army of the seven princes took a chance to breathe, and the battle line approached Huiyang City one step.

The four princes also know the combat power of the Praetorian Guard, no army in the army is its opponent, in order to deal with this Praetorian Guard, the four princes spent a lot of money, gathered a lot of masters of the rivers and lakes, although these people lack coordination ability, but the martial arts are high, can fight with the Praetorian Guard.

The appearance of the masters of the rivers and lakes temporarily dragged down the advance of the Praetorian Guard and temporarily stabilized the whole situation.

The Seven Princes watched the Praetorian Guards slowly appear casualties, and the Praetorian Guards began to fall, more and more, the Seven Princes hurriedly reprimanded and asked: "Where is the 200,000 army in Beiyuan?" The subordinates trembled and said: "Back to Your Highness, our spies can't get out, and we don't know the specific situation of the Beiyuan cavalry!" More than half of the Praetorian Guards were killed and wounded, and most of the masters of the rivers and lakes of the Four Princes also fell, and the army of the Four Princes slowly began to oppress the army of the Seven Princes.

The seven princes were as irritable as thunder, and the four princes were also stupid and restless. Seeing that the army of the four princes broke through the left flank, they were encircling and annihilating the rear in a roundabout way.

The Seven Princes had already thought of withdrawing their troops to defend it, and suddenly saw that the army of the Four Princes began to retreat, and the scouts who broke out came to report: "200,000 cavalry from Beiyuan are attacking Huiyang City!"

Huiyang City suddenly suffered from the enemy, the army pursued and retreated on one side by the army of the Seven Princes, and on the other side had to face the attack of the Beiyuan cavalry on Huiyang City, most of the troops were not in the city, and the loss of Tiexiong Pass was unexpected, and before the army retreated to support, 200,000 cavalry had broken through Huiyang City, and the cavalry rushed to kill in Huiyang City, and the army of the Seven Princes was in hot pursuit, and the general trend had gone.

Not to be outdone, the four princes intended to fight to the death, but the military heart collapsed, the city shouted and killed countless people, the commander was not guaranteed, many soldiers abandoned their weapons and surrendered, the advance speed of the army of the seven princes was even faster, the four princes knew that the general trend had gone, and they were resentful, and ordered someone to kill Chi Heng, but Chi Heng had disappeared.

The anger hit the internal organs, a mouthful of blood, fainted, and the men of the four princes escaped from Huiyang City with the four princes who had passed out.

At this time, there were a few Nanzhou people kneeling in front of the Seven Princes, fearing to pour out the orders of the King of Beiyuan truthfully, and the Seven Princes angrily reprimanded the King of Beiyuan for their treachery.

Ordered these Nanzhou traitors to be pushed out and beheaded. At this time, the secret letter from the Valley of Forgotten Worries came, and Twilight said: "We have found that the envoy of Zhongzhou has appeared in the territory of Beiyuan! The news in the palace of Beiyuan that the king of Beiyuan has come to feast on the ministers in a few days, and it seems that there is a great joy!" The seven princes scolded angrily, pushed it to the table, and smashed the teacup.

He said angrily: "King of Beiyuan, you shameless villain, hypocritical, you actually conspired with Zhongzhou to plot against the mountains and rivers of Nanzhou, and the whole army attacked the Beiyuan army, leaving no one behind!" The military order quickly came out, and the army of the Seven Princes invaded Huiyang City, and got the order of the Seven Princes, and the generals of the Seven Princes watched the Beiyuan cavalry slaughter the people in the city, recuperate women, burn and loot.

At the sound of an order, countless anger rushed into the Beiyuan army, the Beiyuan army was caught off guard, many cavalry were killed, and the Beiyuan general sent someone to explain to the Seven Princes while organizing cavalry resistance.

The angry Seven Princes were even more angry when they heard that the Beiyuan cavalry had invaded Huiyang City and looted it, but the faint uneasiness made him regain a trace of consciousness, and shouted repeatedly: "Pass my order, stop attacking the Beiyuan cavalry!" Everyone thought they had heard it wrong, and the Seven Princes shouted angrily: "Are you all deaf, didn't you hear my order?" The subordinates left in a hurry, and after a stick of incense, the Seven Princes looked at the war in Huiyang City and still did not weaken and scolded: "What's the matter?" The subordinate said: "Our herald has not come back yet!" The Seventh Prince said: "Send someone again, quickly!" The subordinates went to give the order again, and the time for another stick of incense passed, and the Seven Princes sat down and said, "It's over!" The Beiyuan cavalry was trapped in Huiyang City, surrounded by a large army, and the corpses of 200,000 troops were quickly piled up on the streets.
