The bombardment continued, and mushroom clouds rose inside and outside the city, setting off a huge shock wave. Even if this is immature**, even if the way of projection is too primitive, the power of the thunderbolt is still enough to make the Tibetan defenders scatter. In all the previous combat experiences, I have never seen such a ferocious siege weapon, such a lethal power.

After several rounds of free bombardment, the inside and outside of the city on both sides of the tower, which was hundreds of paces long, was already in shambles. Black smoke billowed from the city, and the fire burned the city. The city was even more heavily wounded, and most of the thousands of Tibetan defenders gathered on the city walls on both sides of the city gate were killed or wounded. The living ones rushed down to the city with their heads covered, and fled to the city with their hearts broken.

According to the established strategy, after three rounds, all the Shenwei cannons began to adjust their direction, concentrating their projection points within a range of dozens of steps to the left and right of the castle tower. The Tibetan defenders were also able to have a brief respite. The defending general shouted loudly and the defenders on both sides returned to their defensive positions near the city gate, ready to meet the ** melee siege. The Tibetan soldiers ran haphazardly on the blackened and hot city walls, filling the gaps in the emptied city walls under the coercion of their generals.

However, ** still stood in dense formations at the foot of the hillside, and did not launch a siege operation, because the bombardment had not yet ended. Although the thunderbolt is extremely valuable and the number of troops carried is extremely limited, Wang Yuan decided to let the thunderbolt bomb open a bloody path for the army in order to quickly capture the yak city, so that the soldiers can reduce the casualties of the siege. Even if the thunderbolts were so powerful, it was impossible to expose the entire Tibetan soldiers above the city wall to the thunderbolts. The range and accuracy of the Shenwei artillery determined that the Shenwei cannon could not bomb for the purpose of killing and injuring the enemy, and the correct way was to use the power of the thunderbolt to destroy the enemy's city defense and create more favorable conditions for the soldiers to attack the city.

Half an hour later, all the Shenwei cannons had been adjusted, and the Tibetan soldiers on the city had extinguished the fire at the city head, and simply piled up fortifications on the uneven city head with sandbags. However, their frightened eyes saw that the ** general under the city waved the command flag again, and the trebuchets on the earthen platform began to fire at the same time. Dozens of small black dots flew from the high platform at the bottom of the hillside, all in the direction of the city gate tower and the surrounding area of dozens of paces.

The Tibetan soldiers fled in an uproar, and a deputy general defending the city stood above the city tower and shouted loudly at the soldiers who had fled in all directions, and even did not hesitate to slash and kill several Tibetan soldiers who fled around him. However, with a whistling sound, a thunderbolt hit the stone platform where he had landed, and with a violent explosion, the lieutenant was left with only one arm holding a scimitar and flew into the sky, making an arc and spinning and landing under the city.

With the explosion of this thunderbolt, dozens of thunderbolts exploded together in the city tower, left and right, and the sand and gravel flew sideways within a range of dozens of steps to the left of the city gate tower, black clouds churned, and air waves splashed around with iron pieces and gravel, and the armor and bodies of the Tubo soldiers who had no time to escape were pierced by these unknown things, and were overturned and soared by the air waves. The left side of the city gate suddenly became a place of death that no one dared to approach.

The Tubo soldiers on both sides of the city wall were far away from each other, and no one dared to get closer, only watching the ** bombardment of the area around the city gate tower over and over again. Seeing the black smoke of the city wall near the left side of the city gate tower being blown out of one large hole after another, they finally witnessed the collapse of one side of the city gate. The walls, which were several feet high and one foot wide, crumbled under the continuous bombardment of thunderbolts, and half of the mud and rocks began to slide down, opening a huge gap.

This was exactly what Wang Yuan wanted, and the clever use of the thunderbolt cannons that had not yet been completed at this time in the siege was to destroy the city walls. Wang Yuan wasn't sure if the power of the explosion would have been able to do this, but the results of the concentrated bombing had clearly proved useful. Even if the wall to the left of the gate was only half destroyed, it was enough for the siege.

"Prepare for the siege." Wang Yuan shouted loudly.

Song Jiangong promised loudly, but seeing the flag waving, the Shenwei artillery stopped bombing, but at the same time, the soldiers and horses began to charge up the hillside. Dense Jiannan soldiers covered the gentle slope below the city like a tide surging onto the beachhead, although the defenders of Yak City had already set up countless traps and spiked trenches outside the city, but they could not stop the roaring sea of people from the Jiannan army.

After paying a small number of casualties, the ** soldiers crossed a distance of more than 400 steps and rushed to the bottom of the yak city. They rushed up the breaches along the breaches of the collapsed walls, from the smoky slopes of the earth and rock. Before the Tubo soldiers and horses had time to organize an effective defense here, thousands of soldiers of the Jiannan Army had already rushed up from the gap. Some of them entered the city through the gap, and some continued to climb the walls on both sides, and the city and the city were suddenly plunged into chaos.

The result is obvious, ** occupies an absolute superiority in troops, and the 10,000 soldiers and horses of Tubo may be able to hold on, but they can only retreat in a head-to-head confrontation. Seeing that the general situation was not good, the defending generals issued an order to retreat. More than 1,000 Tibetan cavalry followed the defenders and rushed out of the eastern city. The Jiannan army did not chase after them, but only strangled the remnants of the city with all their might.

The battle finally ended within Wang Yuan's stipulated time. In just two hours, the yak city, which had taken all the measures to defend the city, had changed hands. More than 7,000 Tibetan soldiers and horses were killed and wounded, and the rest fled. ** The price paid was more than 1,000 casualties, which can be described as a complete victory.

The generals swarmed Wang Yuan into the Bison City, and when they passed the collapsed city wall at the gate of the city, they were all shocked and speechless. Most of the walls at the city gate are made of bluestone, which is unusually strong. But it was such a strong city wall that was half destroyed by the bombardment of thunderbolts, which shows the power of thunderbolts.

The whole army marched into the yak city to clean up the battlefield and rest, and Wang Yuan led the generals into the city lord's mansion and sat down in the lobby.

Song Jiangong first stepped forward and said: "Such a method of attacking the city has never been seen in this life, and it is more rapid and effective than when the battle of Nanzhao attacked the city of Yang and Ba. Dashuai, with this thunderbolt artifact, what other city does my Jiannan army have to conquer? Why is it indestructible? ”

All the generals echoed and said that this expedition was actually a little drum in the hearts of all the generals, and the defeat of Wang Zhonghe's army in Shibao City made everyone in awe of the Tubo soldiers and horses. This time with the marshal, the marshal chose to attack to the south, which will encounter more powerful and more Tubo soldiers and horses, and the generals faintly feel that this march may not end well. But after today's battle, the confidence of these people was all high to bursting, and they instantly felt that the Tubo people were weak and explosive, and they were not opponents at all.

Wang Yuan smiled and said, "Although the power of the thunderbolt is difficult to resist, you should not think that you can be fearless if you have this thing. In fact, thunderbolts do not guarantee the invincibility of our army, and the limitations of this thing are obvious. Thunderbolts are expensive to build, we have limited what we carry, and more than 400 of them were consumed in this battle, and our army only carried less than 1,000 in total, which has already consumed nearly half of them. If you encounter a fortified city a few more times, you may not be able to use any thunderbolts. ”

"Build, build this thing." One of the generals shouted.

"Speaking lightly, do you know how much a thunderbolt costs? Artificial and medicine together each cost 20 yuan, just now threw 400 pills at once, that is 8,000 yuan. This thing was made by the marshal himself, the court didn't give a penny, and the marshal almost went bankrupt for this batch of thunderbolts, but you said it lightly. Liu Dehai reprimanded.

The general stuck out his tongue, this thing is so expensive, it was 8,000 yuan away from a mess just now. All his belongings are less than 500 yuan together, and his military salary is less than 10 yuan a month, which is a huge amount of money that he can't earn in a lifetime.

Wang Yuan said with a smile: "It's not going bankrupt, but it's really a bit difficult." And that's not the main reason. The main reason is that the thunderbolt is flawed against the enemy, although the walls of the yak city have been blown down, it is only a small city. The walls of Yak City are not too strong. The height is less than one zhang and five, and the width is less than one zhang, and such a city wall can only be regarded as average. If we encounter a fortified city wall built of rammed earth with a height of two zhang and a width of five boulders, I am afraid that we may not be able to achieve success even if we use up all the thunderbolts. Moreover, this thing is indeed miraculous in siege and defense of the city, but it is not very useful in the big battle between the two armies, because it is too cumbersome and time-consuming to install and disassemble. If the two armies fight head-on, before it can come in handy, I am afraid that it will already be a melee. ”

Everyone was splashed with a scoop of cold water by Wang Yuan, and gradually calmed down. What Wang Yuan said is true, although this thing is hugely powerful, it has no small limitations. If the Tibetans and their own side put on a posture to fight head-on, the Shenwei cannon is indeed of limited use. The head-to-head confrontation still relied on the charge of the horse infantry and frontal hand-to-hand combat. I am afraid that before the Shenwei cannon can be launched, it will be approached by the enemy and lose the combat distance, and the next fate will be destroyed.

Wang Yuan didn't want the generals to have the complacent heart of underestimating the enemy before he blew up the limitations of the divine cannon, and the limitations do exist, but the ways to improve them are not without them. ** is not only used to make shells for the Kamui Cannon, but also for use in melee combat. It's just limited to the constraints of technology and materials, and I don't know when there will be a breakthrough.
