The fire was shining under the night sky, and the shouts of killing shook the sky.

Bonfires and torches glow against each other, and this outlying area suddenly becomes a vibrant city.

Meng Fan stood on a high place and looked down on such a scene.

If you look at it from the eyes of a poet, the world is so magnificent that it is completely worth writing and writing, but he is a bloody battle for life and death.

In order to improve the efficiency of gathering, he deliberately hung up the soul flag, and only collected the Tang Dynasty soldiers, and Tuyuhun and Tubo people were still scattered.

】

Without mercy and emotion, Yan Guogong couldn't think of any good way, the generals of the past dynasties used their lives to fill in, and killed until the flesh and blood flowed like a river, and the enemy had no strength to resist, and then took over this military stronghold.

The shouting and killing continued for half the night, the Tubo people in the stone fort were exhausted, and the Tang army and the Tuyuhun people were in conflict, and no one was willing to fill their lives into the bottomless pit like a moth to a fire.

If only there were cannons.

It is true that the power of thunder is no worse than this, but this cause and effect, Meng Fan does not want to bear it.

What's more, when the two armies are fighting, the national fortune and evil spirit are impacted, and it is difficult to exert the Dao method.

After thinking about it, Meng Fan suddenly came up with an idea, he ordered the prefectures and counties of Longyou close to this place to provide gunpowder-

In fact, this thing appeared very early, and during the Spring and Autumn Period and the Warring States Period, simple gunpowder had already appeared.

And the alchemist just used it as an alchemy, because the emperors of later generations, all of them wanted to seek immortality, and gathered many alchemists to find medicine, and gradually, people knew that mixing sulfur, saltpeter, and charcoal together and igniting them could play a violent burning role.

Of course, the early gunpowder did not serve a military purpose at all, and it had to be improved to make it black.

What the Taoist ancestors discovered, Meng Fan will not purify?

It's just not as powerful as the afterlife.

With the first batch of processed raw materials delivered, an area of the barracks became a testing ground.

[Gunpowder attacked, the sound was like thunder, the heat reached more than half an acre, people and cowhides were broken and there was no trace, and the armor and iron were all transparent]

According to the records of the civilian officials of the army, although there is an exaggeration, it has indeed reached the level of being able to be put into use, which makes the generals excited.

To be honest, Meng Fan regretted why he didn't think of this method earlier, he could sacrifice thousands of his own people less.

And after finding the right ratio, the states and counties were asked to collect poisons, arsenic, sulfur, grass black, croton, wolf venom, a series of things, anyway, whatever is poisonous.

When these things are mixed into spheres, they are mashed and mixed with old paper, hemp skin, charcoal powder and other materials, and then mixed into a lake and applied to the surface......

Datang version of chemical weapons.

It is perfect for dealing with Tibetan livestock.

What kind of humanitarianism can you talk about with aliens who invade the land and commit killings?

Unfortunately, difficulties will always arise.

Going around, any place that is in a safe range, the catapult faces the problem of insufficient range.

But there are always more ways than difficulties, and after some discussion, it was finally decided to build a few dirt mountains by the Huangshui under the cliff, and when the time comes, get the catapult up and launch it condescendingly, which will increase the limited distance!

As for how high the mound should be?

Trigonometric function.

Meng Fan also experienced the happiness of being a scholar, and the mathematics knowledge of junior and senior high schools, combined with the records about the stone castle in the dossier, quickly formulated the relevant values.

The Tubo people don't know about the big killer weapon of gunpowder balls, but just a large catapult is enough for a headache, but they are condescending, and there is no way to take the construction site - the technology is really limited, although they have secretly learned some craftsman skills, and they can also make ballistae catapults, ladders and other equipment, but the quality is not flattering, and the range is greatly reduced, so they cannot threaten the construction site.

If you want to stop the craftsman from continuing the construction, you can only come out of the square platform and solve the problem with melee combat.

Outcome...... Taking advantage of the thick night, the Tubo people really sent a team of dead soldiers.

However, they came too late, and they couldn't do anything about the dirt mountain that had already been repaired, and the fire couldn't be burned at all.

So, these guys lifted the thick wooden pillars to crash, trying to knock down the dirt and mountains like attacking the city gate, but the soil of the military important place was extremely compact, and no matter how they collided, they didn't bounce it.

At this time, the nearby defenders also killed in time.

Finally found a way to fill it without human life, and it has been delayed for so long?

Are you kidding!

After some fighting, the stubborn Tubo people were either killed or maimed, and the idea of destruction was completely eliminated.

On the day of completion, the Tang army also held a very solemn sacrifice to worship the gods.

At the foot of the mountain, horses, cows, sheep, chickens, dogs, and pigs were put on six animals, and five grains, flowers and fruits were presented, and then, the people led by Yan Guogong knelt down together and worshiped in front.

After worshipping, Meng Fan unfolded the manuscript paper written by Lou Shide and read in a deep voice:

"On the second day of the first month of the third year of Fu Weiyi Feng, Li Jinxing, the Duke of Yan of the Tang Dynasty, would like to sacrifice the five grains and fresh fruits, and tell the emperor and the earth, Haotian God, the five emperors of Shenzhou, the Yellow Emperor, the Yan Emperor, the Shaohao Taihao, and the sun and the moon...... Shibao City was built in Sui, which is no different from the Han Dynasty ......"

What does it mean to be famous?

The sovereignty of Shibao City is unquestionable, and this place is the indisputable sacred territory of the Tang Dynasty.

Lou Shide wrote emotionally in the memorial text, warning future generations not to forget the hardships of their ancestors who overcame obstacles and opened up territory in the bitter cold land, which also boosted morale, after all, everyone participated in the battle of justice!

After reading the sacrificial text, Meng Fan was slightly immersed in the sacrosanct atmosphere of the article, and then, wearing a spotless white robe, he took the blood of the animal, knelt and dripped it into the copper basin containing the wine in front of him.

Generally speaking, sacrifices of this specification, except for the Son of Heaven and the prince, are all used by others as trespassing, except for the soldiers who participated in the national war.

Everything is ready!

The Tuyuhun people who were watching the ceremony not far away felt that Tang Jun had become different.

In this way, the prelude to the war began again.

Datang is responsible for using catapults on the dirt mountain, and when it is necessary to rush to the square platform, it is still carried by the Tuyuhun people.

As the war drums rumbled a few times, the sound of tooth ache caused by the violent friction of the wood was heard, and then black smoke billowing fireballs flew into the sky.

At first, the accuracy was not good, there was a certain deviation, and after some adjustment, it became more and more accurate.

Especially after the gunpowder was ignited, a brilliant and dazzling light was ignited in the roar, and eight heavy catapults were thrown in turns, sending the gunpowder balls over continuously.

Not much.

Smoke rose everywhere.

It lasted intermittently for more than an hour, and the stone city located on the cliff was now full of smoke, as if it was shrouded in fog.

Seeing this, the generals became comfortable, and Li Jinxing, the old and serious Yan Guogong, couldn't help but lose his temper, looking back and sneering:

"There is arsenic, sulfur, grass black, croton in this smoke, and almost all the poisonous things in the northwest, enough for them to drink a pot."

"That's right, Jiuru."

"What the hell happens if you smoke these things?"

Meng Fan thought for a while, and said suddenly: "At least the mouth and nose bleed, vomiting and diarrhea, and the worst is poisoned and died." ”

Blacktooth Changzhi laughed: "It's best to poison all these dogs and rats, let's send someone up to take over the city." ”

"Yes, Stone Castle? Iron Blade City? ”

Wang Xiaojie was not reserved at all, stroking his lush beard and smiling: "But Er'er." ”

When the stone-throwing cart stopped, the Tuyuhun marched in formation and rushed up the only path up the mountain.

The city below has been temporarily abandoned by the Tang army, and the two square platforms, one large and one small, have long been devoid of enemy soldiers at this moment, and these guys have either been blown up or shrunk to the top of the mountain.

Meng Fan and the others stared at the top of the mountain, expecting the result, but unexpectedly, after the Tuyuhun soldiers rushed up, they immediately encountered resistance, all kinds of things rolled down, and many slaves who were used as cannon fodder were knocked and rolled over.

From a distance, it looks like an avalanche, many people fall off the cliff, their limbs are still in mid-air, and then they fall at the foot of the mountain, and they are immediately lifeless.

There was a lot of noise, the Tuyuhun people withdrew, and the heavy stone-throwing trucks started working again.

"With so much poisonous smoke, how can these Tubo people still survive?"

"I guess I covered my mouth and nose with a damp cloth, so I survived for a while." Meng Fan didn't care, and said seriously: "Let's continue to smoke them for a while longer, the number of poisonous fireballs is enough." ”

"It's nothing to delay for a few more days, there are many craftsmen in the army, so it's a big deal to order people to continue to transport materials from Shancheng, and it's too late to do it temporarily."

Catapults work in turns, poisonous fireballs one after another, almost day and night.

In addition, there are strong bows and crossbows displayed at the intersection below the square platform, as well as various traps, just to prevent the Tibetan defenders from rushing down from above.

After a night, not only was the smoke on the top of the mountain filled, even the Tuyuhun soldiers guarding the mountain pass could not bear it, they also smelled the pungent smell, some of them had poor resistance, and immediately bleeding from the mouth and nose, and a lot of discomfort followed.

At first, the Tuyuhun people who were used as cannon fodder could still cover their mouths and noses with a damp cloth to hold on, but people always had to breathe, and this method could not completely filter the poison, and finally the Tuyuhun soldiers guarding there received the evacuation order.

Those who are on the edge are like this, let alone the central position?

Meng Fan cast the spell again, and the wind blew for two hours, and the Tuyuhun soldiers went up again to take the lead, and they all wrapped their heads and faces with wet cloths, and charged towards the top of the mountain with trepidation.

This time, he did not encounter any form of resistance at all, and after a while, he saw the general in front of him report that he had broken through the stone castle city.

Most of the Tibetans in the city were poisoned, and the rest of the people hid in a closed stone house, blocking the ventilation holes with various strips of wet cloth, so they survived, but they could not organize defenses.

After the Tuyuhun soldiers went to the city, these remnants of the Tubo soldiers were surrounded and could not get through, and after finding that the general trend had gone, they chose to disarm and surrender.

At this point, Shibao City once again fell into the hands of the Tang Army, and after a few years, the flag with the name of the Tang Dynasty was inserted back on the top of the mountain.

In addition to the beginning of the war, there were large-scale casualties, there was not much bloodshed in the later period, the siege of the city for several days, the dead and wounded soldiers were only more than 100, and all of them were Tuyuhun people, and on the Tibetan side, more than 200 people were killed in the battle, more than 600 people were poisoned, and finally nearly 100 people were captured.

A full battle of thousands of people can block tens of thousands of troops.

It sounds incredible, but that's the way it is, otherwise, Stone City wouldn't be so famous.

After some discussion, these captives were beheaded in public, leaving only the generals who defended the city in Tibet alive, intending to escort them back to Chang'an to invite merit.

Meng Fan was full of interest, climbed the castle and looked down on the mountains, only to see the rivers and mountains in full view, and his heart was wide, but he had no culture, and he didn't want to plagiarize the chapters written by later generations of literati, so he just stared.

Lou Shide, who is not high in official position now, but is destined to be the prime minister in the future, said on the side: "If it weren't for Jiuru's quick wisdom, creating poisonous fireballs, and using clever schemes, I'm afraid that more than 10,000 people would have to die to take this city." ”

"Yan Guogong has ordered someone to report the war to the draft, and the first merit should be undoubtedly Jiuru."

Hearing this, Wang Xiaojie also said: "The military advisor has unparalleled clever plans, and the mystic law is profound, and when he is the first in this battle, the court will inevitably be a marquis." ”

"Poor people are dedicated to serving the country, and fame and fortune are just clouds on the horizon."

Meng Fan shook his head and said humbly.

Next, more and more people stood on the top of the city, silently looking at the surrounding scene.

The mountains are undulating and the rivers are long.

It is undeniable that it is indeed inaccessible and desolate, and it is not an exaggeration to say that birds do not, but when it comes to strategic position, it is indeed very important.

Now, they have taken the stone fort, and in the future, the Hexi and Longyou regions will be connected, the security of the southern part of the Silk Road will be greatly improved, and the trade between the Tang Dynasty and Central Asian countries will become more and more frequent.

In addition, the fertile soil of Longyou will become the granary of the country......

And the Tubo people, before recapturing Shibao City, the soldiers could no longer reach the Tang army fortresses in Hehuang and Longyou.

In addition, the young Khan king of Tuyuhun rejoined the Tang Dynasty, and the fortifications in various places were greatly strengthened, and the Tubo people had basically no hope here for ten years.

In the past years, the famous general Xue Rengui of the Tang Dynasty was defeated in Dafeichuan, almost the whole army was annihilated, and the losses were incalculable, which affected the luck of the Tang Dynasty for decades.

When going on the expedition, they were forced to invest far more troops than in the past, which not only affected the Longyou region, but also caused the people's livelihood in Guanzhong and Hedong to wither, constantly consuming national strength.

And now, their victory in Stone Castle City is bound to have a far-reaching impact that will also last for tens or hundreds of years, and people of insight in the imperial court will definitely be able to realize what it means to win in the northwest region since the second to third year of Yifeng, this time period.

The fact is not unexpected, with the news of the victory of Shibao City, it was introduced to Chang'an by the soldier Pegasus, and before the marching chief Li Jingxuan's recital arrived, the imperial court immediately issued an edict, and passed the military division Meng Fan into Beijing to face the saint.

When the cold winter came, the army would not be used until the beginning of spring, and in addition, the king's order was difficult to disobey, so he set off very decisively.

The number of troops is still sufficient.

The hardest stone city returns.

The method of how to make a poisonous fireball was also taught to some high-ranking generals.

To tell the truth, even if Meng Fan does not return to the battlefield after the beginning of spring, Datang will still win one after another, after all, no matter how backward the black powder technology is, after being assembled on the catapult, it can also form a dimensionality reduction strike.

But...... Before leaving, he left the spirit banner and black talisman behind, and continued to gather the heroic soul.
