When Guo Ziyi and the other generals heard that Zhang Xuān had finally issued the siege order and was about to use firearms, they couldn't help but let out a sigh of relief, and their eyes faintly danced with a light of excitement.

Regarding the huge power of firearms, especially the sky-shaking thunder, Guo Ziyi and others have witnessed and looked forward to it.

In Guo Ziyi's view, if Zhang Xuān was willing to put all the 5,000 sky-shaking thunderbolts he carried into Wuhai City, the Tubo army and horses would inevitably be disheartened and suffer heavy casualties.

But Guo Ziyi and others also knew that the cost of making this firearm was high, and Zhang Xuān easily refused to use it, so no one dared to suggest the use of firearms in person.

Zhang Xuān's clear gaze slid over the generals one by one, knowing everyone's thoughts, and couldn't help but sigh secretly.

Hua originally did not want to use firearms too much, so as not to cause some kind of psychological dependence on the Tang army, and virtually reduce the morale and combat effectiveness of the Tang army. But in order to avoid a large number of casualties, he couldn't take care of much.

If you are tired of taking Wuhai, Shaliuhe will be at your fingertips. And then wave the division to occupy the entire Baihai region, you can extend the entire Liangning Prefecture outward, a radius of four miles ♀ is a vast, abundant water and grass of fertile land, Zhang Xuān is planning... It's been a long time.

If this batch of firearms can be exchanged for this land, it will be worth it∨ Hao thought silently, and waved his hand resolutely and said loudly, "Okay, each prepare!" Shen Shi moments the army to attack the city! ,,"Everyone, can we include this fertile land under our feet into the territory of the Tang Dynasty!" Ben Shuai Xiao everyone worked together, at all costs, to take Wuhai City as soon as possible, and then our army tǐng into the Shaliu River, with lightning speed, to break through Gyatso's lair! ，

"Go to war! , Zhang Xuān struggled to shout, his voice was very hoarse.

He already had a cold, and his throat was unbearable when he shouted so loudly.

"The handsome is mighty, and the last general will fight to the death! ，

"Take Wuhai City and raise the prestige of my Tang Army! ，

Guo Ziyi and the other generals bowed solemnly and bowed to Zhang Xuān.

Guo Ziyi led an army of 10,000 to attack head-on, while Nan Jiyun and Lei Wanchun divided their troops into 10,000 and were responsible for attacking the city from the west.

Dozens of large catapults that had just been assembled appeared in the empty field in front of Wuhai City and in the west, and the Tang army also pressed up as a whole, and the Tubo sentinels on the city tower who were looking forward to observing immediately reacted, the Tang army was about to start a siege!

The sentry blew a piercing horn.

Gyatso led the Tibetan generals to rush out of the temporary headquarters on the city tower, looking down at the Tang army under the city, and their faces became solemn and nervous.

The Tang army finally couldn't hold back and wanted to attack the city.

The Tibetan soldiers rarely had this kind of experience and experience in defending the city, and they were inevitably a little apprehensive.

Gyatso, on the other hand, stared at the dozens of large catapults that appeared on the front and west, his brow furrowed.

Raba leaned over and lowered his voice and said, "My lord, this is the Tang Army's catapult, which is used to attack the city. The skin was filled with large boulders that flew into the city and caused casualties. ，

"Please excuse yourself! ,, Gyatso nodded, "Pass the order, all the soldiers should take precautions, and order the city to close the door and not go out, so as not to cause unnecessary casualties." I don't believe that just a few catapults and a few stones can break my Wuhai City? Joke! ,, If it is an ordinary catapult, although it will cause some damage to the city, it will not affect the defense of Wuhai City. As soon as the Don army began to attack the city, the catapults could only stop, otherwise they would only injure themselves

But what Gyatso never dreamed of was that the Tang Army's catapult was not an ordinary catapult, after Zhang Xuān's suggestion and countless experiments and transformations by craftsmen, this new type of catapult not only has a longer range and more explosive power, but also the stone bullet is mixed with infinitely powerful sky-shaking thunder, this kind of damage and destructive power is incomparable.

There were fifteen catapults on the front and west, which was all that the Tang army carried on this expedition.

Several Tang soldiers operated the catapult in tacit understanding, and behind the catapult, there were rows of Tang soldiers holding siege equipment high and waiting solemnly. The order for siege warfare had been issued, and the mobilization before the battle had boosted the morale of the whole army, waiting for the rain of firearms and bullets to show their might.

A catapult can shoot five projectiles at a time, and one of them is a thunderbolt. The use of the Sky-Shaking Thunder in this way is also Zhang Xuān's arrangement, so that the Sky-Shaking Thunder can be saved as much as possible and its power can be wielded.

After the soldiers were equipped, Nan Jiyun suddenly waved the military flag in his hand.

The whimpering trumpet sounded, broadcasting dàng four fields.

Given the order, the soldiers operating the catapult on both sides unleashed the first round of bullets at the same time.

The rain of bullets in the air roared, drawing a breathtaking arc in the air, shooting down towards Wuhai City.

Most fell on top of the towers, while a few went deep into the city.

The Tibetan soldiers hid in their bunkers, nervously looking up at the stone bullets that broke through the air and the indistinguishable sky-shaking thunder caught in them, and before they could react, an earth-shattering explosion reached their ears

The smoke was filled, sparks were flying, and the towers were trembling slightly.

There are many bunkers that were hit by stone bullets, which is lucky, those bunkers that were directly hit by the sky-shaking thunder, and the Tubo soldiers hiding in them were directly killed in Huangquan, and they were blown up beyond recognition.

The city tower was blown out or smashed out of small potholes, and a single round of bullet rain attacks shook the entire Wuhai City. Whether it was the soldiers on the tower or the civilian slaves in the city, all kinds of screams and vibrations came and went.

Importantly, some of the houses had already caught fire due to the explosion, and sporadic fires began to glow in the city.

Gyatso was so frightened that he rushed out of the bunker to check the situation despite the dissuasion of the generals, and saw that the city tower was in a mess, and the watchtower had been blown up in half.

"My lord, be careful! ,,Two Tibetan soldiers swooped up, pressing Gyatso under him, not far from the left side of Gyatso, a sky-shaking thunder and a stone bullet fell to the ground almost at the same time, and with a bang, the sky-shaking thunder explosion also blew up the stone bomb in all directions, and the huge impact and explosive force suddenly overturned the city wall on one side.

Most of the shrapnel from the explosion penetrated into the two soldiers protecting Gyatso's body, and the two of them suddenly screamed and howled, and the blood flowed into Gyatso's body under him, and his body twitched violently, and gradually stopped moving.

Gyatso faced Sè like land was rescued by the soldiers and hid in bunker.

"What is this, and how is it so powerful? , Gyatso said in a trembling voice.

A trace of fear flashed in the eyes of Raba beside him, and he said in a low voice, "My lord, the junior general heard that Stanley was defeated by Zhang Xuān, the governor of Longshuo, in the city that day, and he suffered a big loss from the Tang army's firearms...," My lord, the Tang army's firearms are so powerful and long-lasting, I am afraid it will be difficult for our army to insist on defending the city

,, Rabah lamented.

Gyatso's face twitched, and he punched the wall of the bunker so hard that blood oozed from his fists.

In fact, the casualties in Tubo were not as heavy as Raba imagined, but the shock of the earth-shaking thunder was too strong, which had already made the Tubo soldiers frightened and the army's morale scattered.

The catapult fired two rounds and then retreated.

This is Guo Ziyi's order. This siege battle was commanded by Guo Ziyi, and Zhang Shu no longer interfered.

Guo Ziyi unexpectedly realized that the shock and blow of this stone bullet and earth-shaking thunder to the Tubo military horses in Wuhai City far exceeded his imagination. In order to achieve the maximum effect, he ordered the catapult to cast a round of 30 Sky-Shaking Thunderbolts every quarter of an hour.

In Kwok Ziyi's plan... , after casting 300 sky-shaking thunders, the Tang army began to attack the city.

Compared with the panic and despair of the Tubo military horses and civilian slaves in Wuhai City, the Tang army outside the city did not take advantage of the struggle, and the voices shouting victory were higher and higher. The stronger the lethality of the sky-shaking thunder, the more confident the Tang army will be.

If it is a continuous cast of xìng, the Tibetans may grit their teeth and get through it. But somehow, Guo Ziyi actually adopted this method of fixed-point and timed strikes, with a strong sense of attack, which was almost a catastrophic nightmare for the Tubo people.

A rain of bullets set off a storm, and while the Tibetans were nervously waiting for the next round of attacks, the Tang army fell silent. But when the Tubo people calmed down a little, a new round of bullets came again. In this cycle, the psychological defense line of the Tibetan soldiers alternated between nervous waiting and fear and panic, and fell step by step.

In Wuhai City, there are already fires, and many houses are on fire, and the flames are soaring to the sky.

On the high slope, Zhang Xuān looked down, couldn't help laughing, he looked back at Xiao Shisanlang, "Brother, this Guo Ziyi is really bad, such a thunder that shakes the sky, attacking the heart is better than attacking the city, it's really wonderful!" ,, Xiao Shisanlang also laughed loudly, "Soldiers who surrender without a fight, in this way, the Tubo people must be disheartened and have no intention of defending the city, and it may be possible to retreat without a fight!" ，

"If so, of course the best. , Zhang Xuān smiled and waved his hand, "Needless casualties have been avoided, and these sky-shaking thunders are worth it." ，

Just as Guo Ziyi continued to organize the bullet rain attack, there was already great chaos in Wuhai City. The Tibetan magnates in the city, each with their own soldiers, gathered under the tower in panic, shouting for Gyatso to open the city gate and let them escape.

In the chaos, there were many sī soldiers who clashed with the Tubo soldiers.

The earth-shaking thunder that fell from the sky shook the heavens and the earth, these Tubo people have been frightened and ♀ are simply invincible divine weapons, the Tang army has this kind of weapon, how can Wuhai City be able to defend it. Rather than staying in the city and waiting for death, it may be better to rush out of the north gate under the protection of the sī soldiers, and there may be a chance of survival, because the north gate is not attacked by the Tang army. @。
