There is not much difference between Qiuci City and the last time he came, there are still no local people, the roads are empty, the population is sparse, the Han soldiers and civilians are concentrated in the south, the front and back of every house are planted with large winter melons, and many people have hundreds of large winter melons on the roofs of many houses, and when they run out of food in winter, they rely on this to survive.

"Guo Yuanjun!"

Guo Song heard someone calling him behind him, and when he turned around, he saw a young general of the Tang Army with a thin and tall figure and dark skin, who looked like he was twenty-five or sixteen years old, but his eyes were very vicissitudes, but at this time his face was full of smiles.

Guo Song felt that he was a little familiar, he thought about it, and suddenly smiled: "You are Xie Tianshan!" ”

The young general said with a look of surprise: "The envoy still knows me?" ”

Xie Tianshan was the guide soldier he met when Guo Song first came to Anxi, and now he has grown into a young and promising Tang Army general.

"Stinky boy has grown up!"

Guo Song smiled and punched him in the shoulder socket and asked, "What is your position now?" ”

"Returning to the envoy, he is now a captain, and he followed Yang Bingma to garrison in Yanji Town, and he only returned to Qiuzi yesterday to do business."

"Not bad! was actually promoted to captain, is the Yang soldier and horse envoy you are talking about Yang Xiaoyan? ”

"Exactly, we are all looking forward to bringing you to Anxi every day."

Yang Xiaoyan was the first scout of the Anxi army to go to Chang'an to report the news, leading Guo Song and three hundred warriors to Anxi, he had not seen him for ten years, and now he is alone.

In fact, Guo Song didn't know that the rank of captain of the Anxi Army was not low, the strength of the Anxi Army was too small, the soldiers and horses were only equivalent to Lang Generals, and the soldiers and horses were the captains below, although Xie Tianshan was young, he was already one of the five captains in Yanji Town.

Guo Song smiled again and asked, "Are you familiar with the end of the city?" ”

"Of course I am familiar, when we were scouts before, the old prince sent us to the end of the city to investigate the enemy, and we stayed around the end of the city for more than a month, and we knew everything over there."

Guo Song smiled slightly: "Then would you like to be our guide again?" ”

"Of course I would like to do it!"

Xie Tianshan suddenly jumped up with joy, he scratched his head and said, "But you have to tell Yang Bingma Envoy, otherwise you will be dealt with by military law." ”

"Don't worry! I'll arrange it so I don't embarrass you. ”

"When will the envoy leave?"

"Set off early tomorrow morning and go to Puchanghai!"

........

Early the next morning, Guo Song led 3,000 cavalry and camel teams back to Puchanghai, and Xie Tianshan also followed all the way.

During this time, the camel team has been transporting grain from Shazhou to this side, and the grain in the Puchanghai camp has reached 100,000 stones, as well as many materials such as fire oil and weapons.

The army was still in intense training, and did not dare to slack off, Guo Song returned to the big tent of the Chinese army, and the soldiers and horses made Li Bing come to report.

"In the past half month, the brothers have mainly trained for night battles, in addition to desert adaptation training, taking soldiers to the desert to march to strengthen their physical strength, and the effect is very good!"

Guo Song nodded and asked, "Is there any news from the Tubo Army?" ”

"Not for the time being, the scouts have been to the end of the city to explore, it is very calm over there, but there are many Tibetan herdsmen found near the end of the city, all of them came from the south after the beginning of spring."

Guo Song pondered for a moment and said, "Leave 5,000 brothers to guard the camp, and another 15,000 people are ready to set off tonight!" ”

"Obey the order!"

In the evening of the same day, Guo Song led 15,000 men to attack the end of the city, two days later, the army arrived in the end of the city, according to Xie Tianshan's suggestion, they stopped thirty miles west of the end of the city, Guo Song ordered to camp on the spot.

In a temporary marching tent, Xie Tianshan said to everyone: "And the city walls of the last city are all built with huge stones, which are very strong, and it is not easy to attack the city, but its weakness is in the city gate, the city gate is made of poplar wood, which is very old, and very dry, easy to be burned, you can attack the city gate with fire, and then open it with a light collision of wood." ”

"Will the defenders of the city block the gates with boulders or sandbags?" Li Bing asked.

Xie Tianshan's face turned red, and he was speechless for a long time.

Guo Song waved his hand and said: "Xiao Xie's idea is very right, attacking the city gate is a wise choice, Li Bing is also right, the enemy is likely to block the gate with sandbags and boulders, then the best way is one word, fast!" Catching the enemy by surprise and giving them no time to block the door requires us to first act at night and then break down the door all at once. ”

"We have prepared two battering rams, and we are willing to fight in battle!"

Guo Song smiled slightly: "And Mocheng is not a big problem, just use it to give us an experiment!"

.........

At the second watch, a 3,000-strong Tang army appeared in the north of the city, about 300 steps away from the city gate, they were prostrate on the grass, and this army could not be seen from the city, and in the rear of this army were 5,000 Tang cavalry.

But tonight's protagonists are five firearms battalion soldiers, to be precise, a large porcelain jar in their hands, this is a porcelain fire thunder from the Shazhou firearms battalion, a total of three, each weighing fifty catties, the shape is like a gas canister, these three have no poison nails in them, they are pure medicine jars.

The five Tang soldiers sometimes ran, sometimes prostrate, gradually approaching the city gate, and there were Tibetan defenders walking around the city, but there were not many of them, and it was estimated that most of them were sleeping.

The five men quickly approached the city wall, there was no moat under the wall, and the five soldiers pressed their bodies against the city wall, slowly moving towards the city gate, and soon reached the city gate.

Five soldiers of the firearms battalion, who had participated in numerous experiments and had extensive experience, first erected a tripod and placed a large porcelain jar on a tripod, close to the city gate.

A soldier threw off the fire fold, the five soldiers nodded, the soldiers directly lit the fire rope, the five soldiers turned around and ran wildly, running more than 100 steps, there was a depression in the grass in front of them, five soldiers prostrate in the depression, covering their ears tightly, and three thousand Tang soldiers also covered their ears.

In a moment, a red flash of fire flashed, and then with a loud bang, the porcelain fire thunder exploded, and the strong shock wave blew a large hole in the city gate.

The 3,000 Tang troops jumped up and shouted to kill the city gate 300 steps away, and the Tubo soldiers in the city were also awakened by the sound of the explosion, and they all got up to prepare for the battle.

The city gate just blew up a big hole, and it was not completely blown up, but dozens of defenders in the city had already fled in fright, and the hundred soldiers who rushed to the front held a crashing wood, they shouted and crashed into the city gate, boom, the city gate was completely knocked open, and three thousand Tang troops were killed, and then ten thousand horses galloped, and five thousand Tang army cavalry killed and rushed directly into the city gate.

........

There were no inhabitants in the city, and at dawn, the Tang army completely occupied the end of the city, and a thousand Tubo troops did not surrender, all of them were killed, and the Tang army also paid the price of nearly 200 casualties.

Guo Song arrived at the end of the city at dawn, and he had been twenty miles away last night, and he had clearly heard the explosion.

There will be no suspense in capturing the last city garrisoned by more than a thousand troops, Guo Song is more concerned about the effect of the first fire and thunder explosion, about one hundred and fifty steps away from the north city gate, Guo Song turned over and dismounted, picked up a piece of porcelain from the ground, and shouted to his own soldiers: "Let's look for it, see if there is any explosive porcelain piece farther away?" ”

The soldiers searched one after another, and soon found more than a dozen porcelain pieces, the farthest was one hundred and eighty steps away, and the data Yang Jun gave him was the farthest about one hundred and thirty steps, but in fact, it was also found one hundred and eighty steps away.

Then the killing range of the poison nail in the porcelain bottle should be not more than fifty steps, but about sixty steps.

Guo Song urged the horse to come to the city gate, only to see that the city gate was blown up an irregular round hole, about one person high, this is still a relatively poor quality wooden city gate, if you encounter the city gate wrapped in iron sheets, the porcelain fire thunder is basically useless.

Guo Song shook his head secretly, the impact of the porcelain fire and thunder was still not enough, it had reached fifty catties, and the city gate had not been blown up.

Guo Song can basically conclude that before the appearance of the iron-shelled fire thunder, the damage to the enemy army by the blast wave alone is not great, and he still has to count on the thousands of poisonous nails that burst out at the same time to play a role.
