On the Gaochang city wall, all the Gaochang defenders are staring at the Tang army under the city as if facing the enemy, after the battle between Gaochang and the Tang army, all the Gaochang soldiers have realized that they really can't beat the Tang Dynasty in actual combat, and now the only thing that can protect them is the Gaochang city wall under their feet, and only by hiding behind the city wall can they bring them a sense of security.

Suddenly, a huge hot air balloon quietly rose slowly from under the city wall, and rose higher and higher, and soon surpassed Gaochang City, you must know that the entire Gaochang City is about five zhang high, this thing has been comparable to Gaochang City, and there is a trend to continue to rise.

"Quick! Shoot it down for me! Although the guard didn't know what this was, he could clearly see that there was a hanging basket under the round monster, and there was even a Tang Army under the hanging basket, and he immediately understood that this must be a new weapon of the Tang Army, and immediately ordered to shoot.

"Whoosh!" The defensive weapons that Gaochang arranged on the city of Gaochang at great expense exerted their power, and for a while, crossbow arrows flew wildly.

However, the hot air balloon was quite far away from Gaochang City, and outside the attack range of Gaochang City, coupled with its increasing height, even the most powerful bow and crossbow in Gaochang City could not hurt it in the slightest.

In the end, the hot air balloon is getting higher and higher, and finally it is directly as high as more than ten zhang, more than twice as much as Gaochang City, even if you stand in Gaochang City, you can clearly see the hot air balloon in the sky.

Seeing an unknown thing, suspended outside Gaochang City, the entire Gaochang City was in a panic, with all kinds of speculations and rumors.

"The shape is like a ball, it can fly into the air, this is probably the hot air balloon that is rumored in Chang'an City, send the order to the people of Gaochang, so that they don't have to panic!" Tang Jun's movement naturally reached the ears of Koji Zhisheng for the first time, and when he came as fast as he could, he looked at the hot air balloon rising outside the city, and waved his hand and ordered.

The hot air balloon in Chang'an City is in an uproar, and it has something to do with the Mo family, and Gao Chang has naturally received relevant information.

"Why did the Tang army raise a hot air balloon outside the city, and what does this mean?" A Gaochang official frowned.

"Judging from the last general, the Tang army must want to spy on our army." One of the generals guessed.

Lu Zhisheng's face suddenly changed, and he exclaimed repeatedly: "It's not good, my Gaochang city defense equipment is also in danger." ”

Sure enough, as soon as Koji Zhisheng's voice fell, a series of whistling sounds hit, only to see the Tang army using trebuchets to attack the Gaochang City Tower, these trebuchets seemed to open their eyes, specifically aimed at the upper city defense weapons of the city tower, and soon the sawdust on the city tower flew wildly, and all the city defense machinery was destroyed.

"Fifty paces west of the castle tower, there are three strong crossbows!"

"Thirty paces to the east, there is a golden sauce pot rack."

Xue Rengui looked up and saw the flag waving under the hot air balloon gondola, and loudly conveyed to the Tang Army's trebuchet the equipment of the Gaochang defenders.

Soon, more than a dozen trebuchets were launched at the same time, and the three strong crossbows on the Gaochang city wall were hit at the same time, and they were immediately torn apart and could not be recovered, and the boiled gold juice was destroyed and scattered all over the place.

"Hit the target, move seventy steps to the west." Xue Rengui received the confirmation of the flag and said loudly, Soon, two four-wheeled carriages carrying heavy objects pulled hot air balloons and slowly moved westward, and the same was true for the trebuchets. Began to follow the Gaochang city wall, destroying the defensive equipment of Gaochang City one by one.

"Hot air balloons! Semaphore! ”

Hou Junji couldn't help but praise the function of the hot air balloon, especially the appearance of the flag, which made the power of the hot air balloon undoubted.

In fact, among the siege weapons of the Tang Army, there are not no siege weapons comparable to hot air balloons, and the weapon nest car that will be used as a supervisor is also ten feet tall, enough to see the whole picture of Gaochang City.

But the nest car and the hot air balloon compared to the fatal flaw, first of all, the nest car is slow to make, it takes half a month to succeed, where is the hot air balloon so fast and convenient, half an hour to the nest car is too bulky once the production is completed, it can not move at all, and the hot air balloon can be easily moved, and then cooperated, enough to destroy most of the city defense weapons on the Gaochang city wall.

For a whole day, on the entire Gaochang city wall, the whistling sound of trebuchets continued, and almost the entire immovable city defense weapons of Gaochang City were destroyed, and the few remaining city defense weapons were all hidden under the city.

When night fell, the entire Tang army camp was cheering, but there was a dead silence in Gaochang City.

"How is the damage to our army?" In the Gaochang Palace, Koji Zhisheng asked a Gaochang general with a gloomy face.

The general stubbornly said: "Back to the king, there are not many casualties among the officers and men of our army, but most of the weapons arranged by our army to defend the city cannot be moved, and they have been destroyed by the trebuchets of the Tang army. ”

Ko Zhisheng's face was embarrassed, Gaochang's troops were weak, and he was already powerless in the face of 100,000 Tang troops, and now he still had the confidence to resist in Gaochang City, which had super defensive power.

And now that all the weapons defending the city of Gaochang City have been destroyed, and the loss of these defense equipment, the defensive ability of Gaochang City has been weakened again, and the chances of winning this war are once again tilted towards the Tang Dynasty.

"The king can rest assured, now the people of Gaochang are united and have the same hatred, even if they lose the weapons to defend the city, they are enough to resist the Tang Dynasty." A general was full of confidence.

Ko Zhisheng relieved his heart a little and mustered up the courage to fight against Datang, but the panic in his heart never lingered, and he fell asleep dimly until midnight.

"Ahh

Ko Zhisheng felt that he was sleeping, and the hot air balloon outside Gaochang City suddenly turned into an eye, staring at him all the time, which suddenly woke him up suddenly.

However, in his sleep, the hot air balloon outside Gaochang City suddenly turned into an eye staring at him in the sky, which made him suddenly creepy and jumped up.

"King!"

The attendants on the side hurriedly stepped forward to put on clothes for Ko Zhisheng, and Koji Zhisheng walked to the high platform, looking at the hot air balloon outside Gaochang City worriedly, this hot air balloon is the eyes of Tang Jun, and has been monitoring Gaochang City.

Suddenly, Koji Zhisheng frowned, and suddenly he found that the fire in the air was getting closer and closer, just when he was puzzled, suddenly an explosion came from the city, and then there was an explosion in the north of the city, taking advantage of the wind to quickly spread into a fire, and the entire Gaochang City was red even in the dark night.

"Someone, go and check, what's going on?" Koji Zhisheng suddenly said angrily.

However, before he could get the report, he saw that the flames of the hot air balloon had come to the sky above the Gaochang Palace.

"Be careful, King!" With the exclamation of an attendant, I saw that a large hall in front of Koji Zhisheng was instantly concentrated with gunpowder, causing a raging fire.

Immediately after a series of explosions exploded over the Gaochang Palace, the entire Gaochang Palace was in a panic, and it was not until dawn that the fire in the entire Gaochang City could be extinguished.
