Throwing a tower is a siege machine that throws stone projectiles, so named because it looks like a staircase.

Its core principle is similar to that of the catapult used by the Tang Army, which uses the principle of levers and centrifugal force to throw stones or other heavy objects forward.

In Guo Rong's opinion, the cost efficiency ratio is slightly lower than that of Tang Jun, and the accuracy is poor, but the power is large enough, and sometimes this thing is not accurate, but it will bring a greater threat.

Guo Rong had seen this thing when he was in Qiuci, but the same thing could play a completely different role in Qiuci and in Longshan.

The area is desert for fifty miles, and it is difficult to find a large stone.

And this is the mountainous area of Longshan, that is, the Liupanshui of later generations, the stone is not too much, and it is almost inexhaustible for catapults or throwing buildings.

In less than a day and night, a full twelve buildings were thrown away, and the Tubo people really brought an accident to themselves.

Looking at the soldiers of the Changying Army around him, and then at Meng Qian, who was both civil and military, Guo Rong was glad that he stayed.

Meng Gan is definitely a master in the field battle, and his physical condition is even more at the peak, whether it is himself or Li Rui is not an opponent one-on-one, but Meng Gan fights too little in the city defense battle.

There is no doubt about the professionalism of the Changying Army engineers, but the wooden fence is not a rammed earth and stone wall after all, and it is impossible to resist the impact of two or three hundred catties of stones in any case.

In the face of the boulder, the armor and iron armor on the long tassel sergeant can only maintain a whole corpse at most, and there is no guarantee that it will not be smashed into a meat patty.

Although Guo Rong had already ordered everyone to disperse at the moment he saw the Tubo people throwing the building, there were still Changying sergeants who were constantly hit at the Schrödinger-like hit rate of throwing the building.

Of course, more stones still smashed on the fence, and after a few rounds of projectiles, under the impact of more than 100 boulders, there were many gaps in the double-layer fence built by the sappers.

Two watchtowers were directly hit, and the moment they were hit, sawdust flew sideways, and the crossbowmen guarding them died directly on the spot.

At the same time as throwing the building and starting to shoot, the infantry of the Tubo people also began to follow, but it was not the Tubo soldiers who walked in the front, nor the siege equipment.

Rather, it was some old and weak women and children in ragged clothes and armed with simple weapons, who had been taken captive.

Seeing these old and weak women and children, Guo Rong shook his head gently, in this era when there are no gunpowder weapons, there are really no new tricks in siege warfare, and driving people to attack the city is almost the favorite way of foreign races, and there is no one.

As for why these captives and forcibly conscripted people would willingly attack the Tibetans, although Guo Rong did not stand on the watchtower, he believed that there must have been a large number of Tibetan foot soldiers with sharp blades standing after these old, weak, sick and disabled.

In fact, the left-handed fellows, dressed in heavy armor, with a shield in their left hand and a spear in their right, followed them closely.

A few hundred paces away was not too long even for the elderly, weak, women and children, and when they were less than two hundred steps away from the outer wall of Camp No. 1, the war drums of the Tibetan army were beating loudly.

The Tibetan heavy infantry that followed closely behind them began to accelerate, and then used the spears in their hands to frantically chase and kill the old and weak women and children who were left behind.

After the blood, the killing, the screams, the wailing, the old and the weak, the women and children also seemed to be suddenly activated, screaming, howling, and began to charge forward frantically.

Seeing this scene, Guo Rong no longer hesitated.

Ci is not in charge of the soldiers!

No matter who they were before, where they came from, and now they appear in front of their own formation, they can only be enemies.

As Guo Rong gave an order, while carefully dodging the stones, the three hundred crossbowmen began to shoot.

The distance between the two sides was two hundred paces, and in the first wave of crossbow arrows, at least fifty people were crossbowed, and there was no even the most basic leather armor, and the old and weak women and children could not block the edge of the crossbow arrows at all, and fell directly to the ground.

There are only two fates for those who fall to the ground, they are trampled to death by the follow-up people, and even if they are lucky enough to escape the stampede, they are killed by the follow-up Tubo people.

Stepping on the corpses of these arrow-hitters, more old and weak women and children charged forward frantically in the frenzied slaughter of the Tibetans behind them, and on the way they were greeted by stones and thistles.

In less than 100 breaths, these old and weak women and children were sharply reduced to less than 800 under the crossbow arrows of the Changying army, the stones with Schrödinger's general hit rate, the scattered and irregular iron thistles, and the slaughter of the Tibetan heavy infantry.

However, under these frantic charges, the lucky ones whose eyes were red had already rushed to a place less than sixty steps away from the outer wall of the Changying military camp.

At this time, the archers who had been waiting for a long time also opened their bows, and for a time the arrows and crossbows rushed at the front, and the old and weak women and children fell in rows.

After dodging bows, crossbows, stones, and thistles, the three hundred lucky men made it to the outer walls of the camp.

However, the deep trenches, the sharp bamboo sticks and wooden thorns inserted in the trenches, and the wooden walls more than a foot high, finally stopped their tracks.

However, before they could hesitate for long, the Tibetan heavy infantry following them had already stabbed out their spears.

In the end, the lucky one's lucky journey came to an end, and the trench with countless bamboo sticks and wooden thorns became the place where their bones were buried.

More than 2,000 old and weak women and children used their lives to open up a channel for the Tubo people to attack, and at the same time consumed at least 10,000 crossbow arrows and 6,000 bows and arrows of the Changying army.

With the sound of tinkling gold, more than 300 Tubo heavy infantry, who had oppressed the old and weak women and children all the way, carefully dodged the crossbows and bows of the Changying army and slowly retreated.

Behind them, more than a thousand tired and ragged young men had been pushed up, while behind them were more than eight hundred elite Tibetan crossbowmen armed with bows and crossbows.

Behind the crossbowmen were thousands of heavily armoured Tibetan heavy infantry armed with hidden spears.

"Whoa, whoa!"

Horizontal knives, obstacle knives, Shangma, Sobo, Hupai, Gusi, Jiare, all kinds of Tang knives and Tibetan knives, hundreds of wooden shields, and hundreds of pieces of chain mail were thrown in front of this young man.

"Put on these armors, pick up weapons, pick up shields, rush to the Tang army camp opposite, kill all the Tang troops, and you will live!"

"You ......"

A bow shot pierced the speaker's throat, and blood splattered in an instant.

"I repeat, rush to the Tang army camp opposite, kill all the Tang army, you can live, otherwise!"

After the words of the Tibetans, the heavy infantry with spears strode forward, and the spears suddenly hit the chests of those young people.

Gradually, the first person picked up the chain mail on the ground,......

"Hahaha, Boss, the road has been opened for you, rush to the Tang army camp opposite, kill all the Tang troops and you will live!"

Raising his hand to look at the person who put on chain mail, held a blade, and walked up on the wooden pier, Guo Rong's expression was extremely solemn and serious, he was also driving the people to attack the city, and he also had a rank, and the person in front of him was definitely not ordinary among the Tubo people.

"Meng Qian!"

"General Zhonglang, take out the Eight Bull Crossbow!"

"Now? This is just the beginning of the war! Two days to go......"

"There are no two days, Duan Lao Fox is right, any accident on the battlefield can happen, today we have encountered hard stubble, we can live until dark and we will make it!"
