The fire is shining brightly under the night sky, and it is really lively to the extreme. Piles of bonfires and little torches reflect each other, as if a vibrant downtown suddenly rises on the ground in this remote place. The people worked in two shifts, even at night, and began to build three earthen mountains.

Xue Chongxun stood on a hillside and looked down at the lively scene, feeling that this lively scene seemed to be full of poetry and picturesqueness. If you look at it with the eyes of a poet, it is true, the heavens and the earth are so magnificent; But in fact, the current Yiqiē is not poetic at all, it is just a life-and-death struggle between two civilizations for living space.

There is no mercy, no emotion, and the brilliant night is just because Xue Chongxun and the others feel that it is more practical to try to use long-range attacks. If you use human lives to fill it in a different way, and the flesh and blood will flow like a river, I am afraid it will be more able to express the essence of this game.

At this moment, I saw a figure coming up from the bottom of the hillside, and the guards standing there did not stop him in the slightest, and he must be an acquaintance. When he got closer, Xue Chongxun really saw that it was Wang Changling.

"It's a good view." Xue Chongxun said very casually. However, Wang Changling hugged his fists unhurriedly and saluted, which was very polite.

Wang Changling's body was not as good as Xue Chongxun, and he was a little tired when he climbed up, so he took a long breath and said: "This place is difficult to attack, and it is difficult to expand it, and no matter how many people there are, it is useless." Thirty miles of narrow land, the terrain is dangerous...... Whoever controls this place will be able to control the Hehuang and even the Longyou region between applause. ”

Xue Chongxun smiled bitterly: "So such a big city can be famous in the government and the opposition, if we capture Shibao City this time, it will definitely be famous all over the world." ”

Wang Changling said: "This city is known as an iron blade, and if there are hundreds of troops in the city, there will be no casualties of 20,000 or 30,000 people...... If the lord's tactics can be effective, it should be called a miracle. ”

Hearing this, Xue Chongxun's mood improved, a smile appeared on his face, and he looked at it with expectant eyes, his heart was full of anticipation. I hope that those gunpowder balls can work and take Shibao City smoothly, so that they can obtain an extremely important strategic place for Datang without spending too much national strength, and return to Chang'an!

…… The dozens of miles from Xishixia to Yaoshuigou were busy, the war had begun, but it had not begun to tear apart, and the people on this side of the Tang Dynasty only cared about building mountains day and night. The main force of the coalition army was stationed on the Huangshui line in the east, and did not squeeze in, and their role was to prevent the Tibetan reinforcements from coming from Shibao City to lead the siege of the city to be annihilated.

However, Tubo was defeated at Jishi Mountain only a few months ago, and it is estimated that he has not yet eased up, and he did not transfer a large army to fight for Shibao City again.

The construction site of the three artificial earth hills was less than 200 zhang away from the stone fort, and the Tang people had already calculated that as long as the height difference was reduced, this distance would be within the range of the heavy catapults. Although they learned some craftsman skills from the Han people, and they can also make ballistas, catapults, ladders and other equipment, but the quality is not complimentary, and the range is greatly reduced, and it is completely impossible to reach 200 zhang, and the accuracy is even worse. If the Tibetans wanted to stop the construction site from continuing, they could only come out of the square platform and solve the problem with melee combat.

Xue Chongxun accepted the Jiannan Army's general's construction and transferred 200 infantry troops to be stationed at the bottom of the cliff for defense. It's useless to deploy too many troops here, so you can only arrange them vertically in the valley and can't open them at all, and you can resist 200 people for a while, and if something happens, you can temporarily increase troops from behind.

At this time, there were no cranes and other equipment, and the speed of repairing the work was really slow, even if it was rushed day and night, it was busy until June in the blink of an eye. The two sides confronted each other in the valley of Yaoshui for a month, and did not even fight a single battle.

Finally, in mid-June, the first battle took place one night. The Tubo people probably couldn't bear the Tang people Xianbei people to repair the fortifications under their noses, and a repair was more than a month, they took advantage of the moon and the dark wind from the square platform to try out to destroy the fortifications, and it happened that the Tang army defenders had nothing to do for a long time to paralyze carelessness, so that their sneak attack succeeded. When the Tubo army came over, the 200 Tang troops had not yet formed a battle formation, and they did not resist at the moment.

Under the scuffle, some of the Tubo people rushed to the foot of the three artificial earth mountains, where there were only a few Tuyuhun slaves who carried the soil and worked as coolies, and they had no resistance, and they were immediately killed and scattered and fled. The Tibetans sprinkled oil on the wooden frames and labor tools, set fires, and burned the wooden things to the sky. But they can't do anything about the dirt mountain that has been repaired, and at this time, there is no explosives and they can't blow it up directly, so they can't find a way to destroy it in a hurry.

So they lifted the thick wooden pillars to crash into the mountain, trying to knock down the earth mountain like hitting the city gate, but the Tang people's construction method was based on the solid earth, and the soil was rammed very strong, and it would not move for a while after being hit.

Xue Chongxun also heard the news of the raid, and immediately ordered Zhang Wulang to transfer troops to quickly reinforce him, and at the same time joined up with Tuyuhun and asked him to transfer Tuyuhun troops to continue to follow up with the follow-up troops.

Zhang Wulang transferred three regiments of cavalry and quickly rushed to the stone fort, and a fierce battle broke out immediately, and the Tuyuhun army behind also came, filling the narrow valley to the brim, and sure enough, there were too many people.

Xue Chongxun climbed to a high place to see the situation on the battlefield, but he couldn't see it clearly at night, he only saw the fire flashing in front of him, and heard a noise in his ears, anyway, the fight started. He was also a little anxious in his heart, mainly because he didn't know much about construction, and he didn't know what kind of damage the earth mountain could withstand, if the construction site that had been worked hard for more than a month was completely destroyed, wouldn't he be busy?

He asked Zhao Si from the workshop: "Will the earth city you built collapse?" ”

But Zhao Si judged that this person was most afraid of taking responsibility, and Xue Chongxun also knew it for more than a month since they got along. As expected, Zhao Si said hesitantly: "There is no problem with the materials and structure, and it will not collapse generally, but if it is artificially destroyed, it is difficult for the lower officials to say......

If this is ambiguous, Xue Chongxun can't tell what the situation is. Of course, Zhao Siju will not pat his chest and guarantee: he is an engineering student, and he is only responsible for construction, anyway, it is none of his business if the earthen city he built does not collapse by himself; It is the responsibility of the garrison to be artificially sabotaged, and it is his business, of course, Zhao Si can't be sentenced to be the black pot for others.

Xue Chongxun frowned, and his heart was very depressed. If the previous achievements are wasted, it is not just a matter of delaying time, the coalition army of nearly 100,000 people on the shore of Huangshui in the east, mainly Tuyuhun people, will have to eat and drink how much food and drink every day! This battle is a fight for national strength, so that the Tuyuhun people are so consumed, and their little territory may not be consumed.

After he realized the strict nature, he immediately wrote an order in his own hand, ordering Zhang Wulang: to repel the enemy army and recapture the construction site within half an hour.

Zhang Wulang was supervising the battle behind the officers and soldiers of the third regiment of Jiannan in front, and after receiving the letter from the herald, he unfolded the paper and looked at it under the firelight, Xue Chongxun's handwritten letter, and he immediately realized the seriousness of the matter.

He looked up and saw that the front was densely packed with people, and swords and guns flashed brightly in the firelight. Originally, it was the cavalry that came to reinforce them, but now they all dismounted to fight, because the place was too small for the infantry army to be densely arranged.

The subordinate general next to him said: "The place is too narrow, and it will take too much time to unleash." ”

Zhang Wulang said angrily: "The herald orders the front army to advance, kill the bloody road, and those who take a step back, the captain's team is all beheaded!" ”

The war drums beat in the sound of killing and screaming, and the cavalry of the Tang Army who dismounted were still wearing heavy two-gear armor, and it was impossible for the dense formation of people to even turn around, what other martial arts tricks could be said at this time? There is no place for you to compare at all, you will be stabbed when you see someone, or you will be stabbed by someone, you can only carry it hard, and there is no place to hide.

Some generals shouted loudly: "Stand firm even if you die, don't fall...... this situation, and when you fall, you will be trampled into pulp.

Arrows flew overhead, and no one knew when an arrow would pierce into the flesh from a thin part of the armor on his body. Everyone's eyes widened, most of them had fear on their faces, what kind of death was nonsense, risking death to move forward was just a duty, and retreating was just a crime.

Fortunately, the combat effectiveness of the Tang army was really stronger than that of the Tubo people, and the equipment was also better, and the shape was already obvious.

When the sky gradually whitened, the Tang army finally recaptured the construction site, and Tubo retreated to the square platform. The Tuyuhun soldiers behind did not come in handy, and at this time they were ordered to pursue, and followed the Tubo rout to rush to the cliff path...... The result was obvious, it was smashed back by a mess of rocks and wooden ballistas, and many people died, and they died inexplicably.

Zhang Wulang walked to the construction site to take a look, fortunately, the three dirt mountains were still standing high there, but the wheelbarrows, wooden frames, ladders and other things around were all burned to the ground, and the embers were still emitting green smoke.

Xue Chongxun then came to the construction site to inspect and saw that the fortifications had not been damaged, so he breathed a long sigh of relief. It's not a big deal that the tools are destroyed, it's just a matter of transporting them from behind.

There was still a smell of burnt and bloody in the mist, and many corpses were scattered in all directions, broken swords and broken spears were inserted crookedly in the soil, and the army was silently carrying the corpses and cleaning up the battlefield.

Xue Chongxun asked coldly: "What about the person in charge of guarding the construction site, is he dead?" ”

At this time, a general with his hair in a messy bun and wearing armor hurriedly rushed to this side, and before he could reach the ground, he was stopped by Xue Chongxun's guards and confiscated his saber.

"The last general is careless and misguided, and the sin deserves death!" The general hurriedly fell to his knees.

"You're so right." Xue Chongxun waved his hand, "Drag it down and cut it, and the first level will pass on the three armies!" ”

Four or five sergeants immediately pounced, knocked him to the ground, grabbed his arm, and left. The general's face was desperate and he couldn't say a word...... His own sin deserves death.

Within a moment, a "click" was heard, and the general's head rolled into the ground. Xue Chongxun looked around at the officials and generals and said: "The construction site is almost completed, whoever derelicts his duties and makes a mistake will cut him!" ”G
