The power of black gunpowder is limited, and it is impossible for Xue Shao to make too much in a short period of time. So the big bang didn't actually kill a few people. What really brought the greatest destruction to the Turks was the great collapse of this earth-destroying formation and their new camp in the mountains, and the ensuing collapse of the army and the chaos of men and horses!

After inspecting the tunnel dug by Yu Hongye for the first time, Xue Shao had the idea of the current situation in his heart. Initially, the idea was to bury the explosives under the feet of the old camp where the Turks were located, because there was a ready-made labyrinthine tunnel in the form of a "spider's web".

This may seem easy, but it's hard to actually do. Because the Turks are not stupid, they always keep an eye on what is going on underground. The labyrinthine tunnel was too close to the ground for easy detection.

Despite this, Xue Shao had no other better choice at that time, until Guo Yuanzhen took the initiative to propose a "fraudulent surrender" to delay the army, so Xue Shao "incidentally" gave Guo Yuanzhen another impossible task - to trick him into moving to the western foot of Qingyang Mountain.

The underground passage used by Yu Hongye to transfer materials directly runs through the entire Qingyang Mountain, until the east foot of the Yinchuan Juntun is the exit, which is more than ten miles long. Otherwise, her supplies would have been spotted by patrolling or sergeants on the watchtower as soon as they left the tunnel.

The tunnel winds all the way through, and there are many air holes. The tunnels were dug by professional people, and the holes were designed so that they would not cause rainwater to back up and would not be easily spotted by people on the ground. What Xue Shao had to do was to make full use of these holes to bury explosives, and dig more small passages around the big tunnels to bury more explosives. In order to save as much manpower as possible and shorten the construction period, these small tunnels are narrow enough for one person to climb in at most - and then bury the explosives!

Xue Shao also made two preparations in advance, if Guo Yuanzhen failed, then he could only continue to take the first-hand plan and blow up the original military camp. If the operation is discovered, it can only be an emergency plan of "rapid blasting" by one's own people rushing into the tunnel with explosives...... That's why Xue Shao solemnly selected fifty dead soldiers and signed a life and death contract!

Moreover, this emergency plan is likely to lead to a major collapse of the entire tunnel, thus endangering the Yinchuan military camp itself. When the time comes, half of the military cantonment will most likely collapse and be buried with the Turks!

Xue Shao really can't control how many of his own people will be buried by the Turks, and it is very likely that he will be included, because he will definitely be very close to the blasting point - in order to win this damn war, anyone can be sacrificed, anyone!

Fortunately, Guo Yuanzhen succeeded, so everything was perfect.

After the explosion, the ground of the Turkic camp collapsed like a spider web. Due to the large number of people and horses and the accumulation of materials, this spider-web-like local collapse soon evolved into a large-scale collapse.

The rumbling explosion, the sudden collapse of the ground, plunged the Turks and their horses into great panic and confusion. All order and command lost their effect, and they began to instinctively flee in a hurry!

Just moments after the explosion, some Turkic people who had not completely lost their minds suddenly noticed that many of the "grass and trees" on the top of the mountain above them seemed to be moving. At first, they thought they were frightened out of the hallucination, but it wasn't until those "grass and trees" showed a large red flag of the Tang Army that they suddenly realized - it turned out that there was an ambush on Qingyang Mountain!

Duan Feng, with his thousands of brothers, hid on Qingyang Mountain for a long month and a half, covering his body with a lot of grass and trees every day as a cover, not daring to move, never bathing, and rarely eating hot food, all of them were already like savages. Now, at last, it's time for them to raise their eyebrows. But Xue Shao's order was not to allow them to rush down the mountain to do a big job when they wanted to kill the most, but to use another way to entertain the Turks who were unable to form an army first-crossbow!

Wooden single crossbows, bamboo pole crossbows, and Fuyuan crossbows, these three non-individual giant crossbows, all belong to the "heavy weapons" category of the Tang Army. Because they are inconvenient to carry and difficult to operate, they are generally used for attacking and defending cities or large-scale field battles. The arrows of these heavy crossbows are not made of ordinary arrows to be sharp, but made into the shape of a large shovel or hammer, the main point is that they are heavy enough and heavy enough, so that they can cooperate with the powerful ejection power of the crossbow bed, so that the crossbow arrows can fly far enough and kill enough.

However, today, the crossbows of these giant crossbows that Xue Shao sent to Duan Feng from the tunnel were all replaced with another strange appearance that they had never seen. They grew longer, thicker, and heavier, and seemed to have a lot of stuff in them. The head of the arrow has become much larger, like an iron urn.

Although he was curious, Duan Feng didn't have time to study what was so special about this strange thing. Seeing that the Turks below were in a mess waiting to be slashed, he just wanted to shoot all these crossbow arrows quickly, so that he could go down the mountain and kill them.

The red flag was displayed, and Duan Feng hissed and roared - "Release!" ”

Hundreds of stout iron arrows of strange shapes roared into the sky, and then fell from the sky against the Turkic camp. After landing, it exploded!

Duan Feng and the soldiers were stunned, and then there was ecstasy - good thing!

The Turks suffered even more now, after all, the explosives that Xue Shao buried under their feet were limited, but the bombing attacks from the top of their heads were endless!

He was not killed, but after being attacked by a round of crossbow arrows, he felt the urge to draw his sword and kill himself.

Fooled!

fell on Guo Yuanzhen's evil!

When he moved to the western foothills, the purpose of the expedition was to get rid of the catapult attack launched by Xue Shao "probably". Now it's a good thing, he obediently got into the range of Xue Shao's ballista - who knows how many people he had ambushed on the mountain!

"Removal ——!!"

Although he knew that the order was not of much use, he still gave such an order. Then he took his guards and frantically retreated south. The purpose, of course, is Lingzhou.

At the most critical moment of life and death, Du Xilu did not completely lose his mind. He knew very well in his heart that the defeat was like a mountain, the situation in front of him was difficult to control, and it was impossible to fight back and turn the tables. This game was lost, but Lingzhou still had the last base area, and there were still thirty or forty thousand fresh troops. If you can withdraw as many men and horses as possible from here as soon as possible, and once you join up with the Lingzhou army, you will still have a lot to do!

Under the guidance of Duxilu, a large number of Turks, who had not been affected by the explosion, began to retreat to the south. But many of them fled in all directions, unorganized and blind, southeast, north, west, and north.

Duan Feng was in a hurry!

"Launch, launch, launch! After ejaculating, go down and cut off the dog's head!! ”

Crossbow bolts rained down in the air, blasting black thunder after black thunder in the crowd of the Turks.

"General Duan, the young marshal has an order!" Duan Feng, who was fully engaged, was suddenly awakened by a shout, and when he looked back, it was Guo An who had come to deliver the order in person.

Duan Feng didn't dare to slack off, and hurriedly asked the young marshal what his order was?

Guo An said: "The young marshal strictly ordered that General Duan should not pursue the fleeing enemy troops in all directions, but only sweep the enemy at the western foot of Qingyang Mountain, and be responsible for taking over the enemy camp and collecting prisoners to clear the baggage. ”

"Yes!" Although he was a little puzzled, Duan Feng solemnly promised.

"Farewell." Guo An turned around and left.

"General Guo, wait!" Duan Feng hurriedly stopped him and said with a grin, "Can you tell me, where did my good brother Niu Ben go?" ”

Guo An smiled slightly, "Confidential." ”

Duan Feng didn't say a word, turned around and ran to the side of the ballista and waved the flag high, "Release!" ”

In the military fort.

Guo Yuanzhen and the soldiers who were waiting in formation heard that there were bursts of explosive cars coming from the direction of Qingyang Mountain, and they couldn't hold back their blood. But Xue Shao just refused to give the order to let them rush out, and he was in a hurry.

"Young marshal, when will the order be given?" Guo Yuanzhen has always been calm, and he couldn't help but ask for the third time.

"When the explosion stops, it's fine." Xue Shao smiled indifferently and said, "You shouldn't be willing to die in the hands of your own people, right?" ”

"Okay then......" Guo Yuanzhen smiled bitterly, "Wait!" ”

After a long time, the explosions finally stopped. The red flag envoy on the watchtower also waved a flag, indicating that the friendly forces on Qingyang Mountain had stopped bombing and attacking, and the infantry troops could attack and clear the enemy.

"It's time." Xue Shao said to Guo Yuanzhen, "Take your knife and your people, and go out to clean up the Turks!" ”

"It's been until this moment!" Guo Yuanzhen turned over and pulled out his sword, "Sons, rush out with me and cut off the dog's head!" ”

A cavalry like a wolf and a tiger, followed by a general like a wolf and a tiger, rushed out of the horse of the Yinchuan military tun like an angry wave, and killed the Turks who were defeated by the army.

Xue Shao carried a pot of wine and climbed the highest watchtower in Yinchuan Juntun.

Looking down, black smoke billowed everywhere, flames were raging, people and horses were as small as ants, and the mountains were majestic.

A woman, who was quick and fast, climbed the watchtower and came to Xue Shao's side, grinning and picking up the wine jug, "Please pour the first bowl for the young marshal, the wine for celebration!" ”

Xue Shao smiled indifferently and was noncommittal.

Mei Rakshasa was quite excited, and hurriedly poured a bowl of wine and handed it to Xue Shao.

"Young marshal, please!"

Xue Shao picked up the wine, lowered his head, and stared.

"Look, drink!" Mei Rakshasa was a little anxious, "Could it be that you are still worried that I will be poisoned?" ”

Xue Shao smiled indifferently, "I'm not here to drink." ”

Mei Rakshasa was stunned for a moment and muttered, "Then what are you doing here?" ”

"Respect, thousands of living beings!" Xue Shao raised his hand, and a bowl of wine flew down from the highest place in Yinchuan Juntun.

"If you don't drink, don't mess up! …… I drink! The Rakshasa picked up the flask and drank violently.

Xue Shao glanced back at her, and couldn't help but smile bitterly: Why is it not Taiping who is by my side at this moment? She must have understood what I was thinking.

Shangguan Wan'er must be able to understand.

Well, and Xuanyunzi......
