The appearance of Tongwan Cannon quickly increased the speed and weight of the Tang army's siege.

With the sound of thunder as the iron box falls, their long swing arms ejected in turn, just like the arms of giants that are constantly shaking. The stone bullets thrown by huge centrifugal force can fly out 500 to 100 steps away. It is not as low as the big copper cannon, and it is specially used to defeat the towering enemy towers on all sides of Wancheng.

In just two days, the "Kangdi Tower" in the northwest corner of the city was shot through seven stone bullets. The buildings made of several woods were hit into powder. The Xia people stationed on the enemy building looked at the clouds in despair, and then there was a heavy whistling sound. The stone bullets shot from the huge stone thrower of the Tang people were rolling sharply in the air, flying, piercing through and tearing the flowing clouds, and then accurately smashed into the tall building, making a sound like the sky collapsed and the earth sinking. The broken wooden beams and the remains of the victim were wrapped in stone bullets running around, piercing out from the outside, smashing into the territory in the city, causing even greater casualties.

Kangdi Tower is also a symbol and pride of Tongwan City. Under the heavy impact again and again, the upper and lower layers shaking and dislocating, and finally collapsed and destroyed with a terrifying cry. After the huge smoke and dust spread out, it disappeared in the eyes of the Xia people in the city, only a pile of blood-stained ruins and rubble on the white city walls.

The Tongwan Cannon was easily destroyed, but it was completely impossible for the Xia people to rebuild the enemy building. The Tang people used camps and cavalry to occupy all areas suitable for harvesting and collecting water, and the entire Tongwan City had been surrounded as strong as an iron hoop.

The head of Prince Nixiang, the great king of Shannan, was lifted on a high pole and erected in the front wall. Almost every Xia people in the city could see him when they climbed up.

This is the outcome of the rebels.

Two days later, the corner tower "Flying Sky Tower" in the northeast of the city was also shattered. Fifty Xia people who were sticking to it collapsed with the building, and many people could not even find their bodies.

In this way, the northern section of Tongwan City has no high-level fortifications that can be condescending to stop the Tang people from siege.

What is even more terrifying is that there are two cities in the east and west (Luocheng to the west and inner city to the east). Now, the number of guards and the Pingxia people who rushed in is nearly 40,000, and there are also many cattle, sheep, dogs and other livestock. As long as the Tang army launches a stone bullet from the Tongwan cannon, even if it cannot hit the enemy's corner tower, it will cross the city wall, draw a long arc, and fall into the city. It will immediately be a tragic scene of casualties and injuries: the remains of people and livestock are piled up day by day, and can be cremated at first, but the number will increase. If it continues for a long time, it is very likely that a plague will break out. At that time, Tongwancheng will not survive.

The Tang army surrounded it, even if it did not come in, Tongwan City would have to turn into a hell on earth and destroy itself in the plague.

There are crying summer people everywhere.

They don't know when death will come upon them, but they all know that it's only a matter of time.

I can only wait for the Tang army to give them a second path, and the choice is in the hands of the other party.

Before the emperor came to "watch the hunt", he was in charge of Pingshuo Gate in Wancheng. Moved rats stood under it with compassion on his face, and looked up at the clasp and led his bow to his Xia people, shouting: "Subdue, surrender, surrender under the punishment given to you by the Emperor Tian, ​​and then clear your sins. This is the only way."

On the left side of the mouse, there was Yuan Hui's youngest son Sheng, and on the right side was Zhou Ziping, the envoy of the Tang army's persuasion of surrender.

Behind them, two Tang soldiers were pulling a leather chariot, and there were corpses covered with white cloth.

Soon in Zhenzhu Tower, Yuanhui hugged the body of his eldest son who was coated with lime and was deeply saddened, and in an instant it seemed that he had become ten years older.

Although his youngest son was sent back, for Gao Yue, it was just a cat who changed the captured mouse from the left palm to the right palm.

The trip of Xiaofeng Momo was to persuade him to surrender.

"My Emperor Tang immediately came to the expedition here. After slaughtering Bai Chengzi, he would use the head of Pingxia tribe to build Jingguan, and then face the river to promote the northern border. Now, Mr. Ji came here to tell you before the car arrived, and gave you the last chance to surrender. Bai Chengzi still had the possibility of avoiding the massacre of the city!" Zhou Ziping waved his hand and scolded Yuan Hui, who was sitting in the hall.

Moved mouse's expression was calm and he didn't say a word.

At this time, Yuanhui's hair was loose, and he turned his face to the side, and did not reply to Zhou Ziping for the time being.

"You have no chance of winning. The gang tower collapsed in front of our giant cannons, and the Wuding River was cut off. The city was short of water soon. What if there was some food and livestock? It would only happen sooner. Since entering the city, I have witnessed all kinds of miserable situations. If you truly love the tribesmen, you should ask them to leave the city as soon as possible to surrender. Otherwise, a huge amount of divine thunder gunpowder had been sent here from Mizhi. Ji Gong said that he would dig out the tunnel immediately and use gunpowder to ignite the walls of Baichengzi."

"The wall foundation of Tongwancheng is airtight and the blade cannot be cut into. It is difficult for your gunpowder to collapse them." Yuan Hui retorted lightly.

"Then try it out, but why use the lives of hundreds of thousands of tribe members as bargaining chips? Even if the gunpowder cannot be knocked down, we can still put the rotten corpses of the Xia people who died in the battle on Hei Shuiyuan in the skin pocket of Tongwan Cannon Cannon, throw them into the city like a projectile to inspire plague infection, and you will still have to die, so Tuoba Chaohui, you are doomed to fail."

At this time, Moe Moe slowly knelt down, stretched his hand to Yuanhui, with a gentle look on his face, "Sacrifice is a sacred and noble thing. If you can eventually save the whole city, then in terms of faith, you are still the well-deserved Emperor of the Blue Heaven."

Yuan Hui was lying on the ground at this time, bowed deeply to Zhou Ziping, the Marquis of Yu of the Tang Army, and said, "I am willing to abolish all my names, surrender to Ji Gong, and surrender to the Tang Dynasty, but I hope to treat my Pingxia tribe well."

"Duke Ji has signed with Jia Pushe and Du Menlang to ensure that after Tongwancheng opens the city and surrender, he will not kill a person. However, he will no longer set up prefectures to settle Pingxia Dangxiang, and the entire tribe will be separated. He will be treated as a Qiang household in the Tang family and under the guidance of the government."

Hearing the conditions reported by Zhou Ziping, Yuan Hui's face was tightly pressed against the blanket, his teeth twisted and bitten the blanket felt, his heart was filled with despair and endless humiliation. He said that he was "making a plan under the guidance of the government", but he was actually a slave... As for himself, he was afraid he would leave in disgrace.

The Blue Emperor, so fast, became a falling meteor in history and a dissipating spring dream.

When Zhou Zi Pinghe returned from moving rats and brought back Yuanhui's promise, Gao Yue was very happy, "Go to pass the message again. When the imperial guards arrived in person three days, everyone in Pingxia Dangxiang gathered in the west city, and all the heads of the big surname gathered in the east inner city, and then opened Pingshuo (north), Song (north), Liang (west), recruited the four Luocheng gates of Wei (east), and let the Tang army enter and occupy all battlements, and the enemy building. Pingxia must not have one person holding a military stick, and no one standing on the city. As for Tuoba Chaohui himself, he was the leader of Yuan Ni, and he was tied up and knelt down at Fengyang Gate of the inner city to welcome the heavenly army!"
