There is a specific time for concrete to solidify. It usually takes twenty-eight days, and the hardness of seven days is about half of the specified hardness. In this case, the concrete column can only be poured thicker to support the pulling force of several tons of artillery. It is fine to turn the corner, but a hundred steps down the mountain pass is a dangerous place. Fortunately, the Chu army does not need to stick to it for seven days. Once the pouring is completed, the concrete column can be buried and removed. If it attacks again in seven days, the Qin army will not care about the extra protrusion on the ground.

It was precisely because of the seven days of solidification that Chengtong hoped that Lu Chuang could attack today, so that the pass was pulled down within ten days - the pass in front of him was just the first dangerous step to go around from the mountain to the Mianshui. After climbing the Yuanwu Mountain, there was also a mountain ridge from east to west to the top of the mountain. In the name of later generations, the pass was called Qiantong Mountain. If you climb Qiantong Mountain and walk more than ten miles northwest, it is the real Yuanwu Mountain, which is Fengling after Qin. Only after crossing this Fengling, which is two thousand meters above sea level, can the entire pass be considered truly broken.

'The road to Shu is difficult, it is harder than climbing to the blue sky'. Fengling is the highest peak on the road to Qin and Shu. Li Bai couldn't help but sigh so much after passing by; Du Fu wrote on the spot when crossing Fengling: 'The horse's feet are lowered and the tree is approaching, and the peak's waist is facing the sky.... The wall stands halfway on the day, and it is not a single majestic person.'

This path was officially dug in the Western Han Dynasty. Hundreds of years later, the Tang Dynasty was already a major road. However, in the pre-Qin period, this mountain road that was not officially passed was extremely deep. Because the mountains were high and the sun had not yet set, the peaks were surrounded by clouds and mist. The next morning, the mountain stream was blocked with mist. The battlefield of fighting suddenly became a fairyland on earth. Lu Qi, who had never liked sentimentality, was amazed at the changing clouds and fog.

"Report to the brigade, time is coming!" Zhang Han, a brigade Sima, said. Adhering to Sima's responsibility, he also said: "This battle is a good thing."

"Good!" Lu Chuang didn't care much about the good and bad fortune of divination. Good fortune was necessary, and bad fortune was also necessary, but he knew that the soldiers in the brigade were very concerned about this. The news of divination was announced immediately, and the soldiers immediately cheered.

"Ju Jun's Belt?" It is very convenient to stand on the top of the mountain to see the foot of the mountain. After the fog gradually dissipated, Meng Tian personally supervised the formation and must not let the Chu army pull out Motianling.

"Lu Cang." As a counselor of the Ba people, Fan Mu was very familiar with Lu Cang. "There is also the false king Lu Gao, who is a man of many tricks, and it is the harm of my Great Qin."

With Lu Cang's military flag, it is naturally Lu Gao's military flag. Both of them are both fame and rank, and their rank is actually the same as Linwu Jun Pang Nuan, but their fame is not as great as Pang Nuan. At this time, many generals of Chu emerged, and they can be called fame, so they should not be underestimated.

"That's not to break my stronghold!" Meng Gong's words were firm. Before he finished speaking, the sound of drums on the hillside suddenly came out loud, and there was no shelling. The soldiers of the siege brigade holding a large shield rushed upwards.

The people of Ba people were most afraid of artillery. The Chu army abandoned artillery instead of using it. The soldiers of Ba people stationed at the corner did not believe it. When the enemy advanced more than a hundred steps, they burst into cheers and raised their big shields to greet them. When they reached fifty steps, the soldiers who were raising their shields shouted loudly: "Shield!" Hundreds of soldiers suddenly gathered together quickly, and the shields in their hands were stacked to form a thick shield wall. The soldiers either stood or squatted, and all of them hid behind the shield wall.

The city walls are narrow and it doesn't matter. Fighting against the Ba people in Langzhong on the flat ground, the thin tortoise shell formation is not enough. The Ba people have their own Mu crossbows. Back then, they used this Mu crossbow to shoot and kill the Bingjun Ba people who resisted, and helped Qin rule Bashu. This powerful crossbow made of cow horns is equivalent to slashing, and no matter how hard the shield is reinforced, it will penetrate it within a hundred steps.

After all, people came out of the Battle Department of the Grand Sima Mansion. At the suggestion of Lu Gao, the swords, shields and soldiers no longer had any tortoise shell formations. The soldiers' large shields directly formed a thick shield wall to resist the Mu crossbows of the Ba people.

The sound of arrows shooting shields with the sound of arrows shooting. Even if the shield walls are stacked, many arrows still penetrate the shields, stabbing the soldiers holding the shields. It is tolerant to scratch their arms. If they shoot through the shield-holding arm diagonally, some people will scream loudly. No one cares about this kind of scream. If the crossbow arrows can be shot for three rounds at most, the Ba people will rush over to rush. In addition to the large shields, there are also copper axes. When the Chu army quickly dispersed and formed a three-line formation, the copper axes in their hands were already slashed hard.

"Border! Front..." Lu Gao, who was standing behind holding Lu Lijing, heard the shouts of the pawns' commanders, and the third line of formations were not fully unfolded. "It seems that soldiers must be equipped with javelins when siege."

The siege brigade did not use javelins when siege, and mainly relied on short swords to fight. Now, he suddenly switched to the flat ground to fight and rushed to help quickly, and there was no time to transport javelins. At least there was no one today. The Ba people had Mubi. Mubi's like javelins, and they did not want to kill many enemies. Mubi's real function was to bring some chaos to the enemy's formation before the war was fought, so that they could not form a complete line. The Ba people had Mubi's crossbow, so their three-line formation was not fully unfolded; they did not have javelins, so the Ba people rushed over calmly, slashing hard as soon as they came up, and the soldiers were at a disadvantage.

"It's my mistake!" Lu Chuang closed his eyes in pain. He thought of almost everything, but he didn't think of the javelin.

"It's okay. In a moment, the Ba people will lose their power." Lu Gao didn't care about the war in front of him. He understood the Ba people's tactics. As long as he withstands their first wave of offensives, he would be killed by his side later. "Why didn't the woman see you today?"

"You..." Lu Qi wanted to be angry but stopped. The Ba people were martial, and men and women in the tribe would go to fight. After careful study, the Ba people in Langzhong had close relationships with the Zhou people, and their skin was whiter than those of Junba and Yue people. Lu Gao, who was not well-known for his talent, drank too much wine, and his favorite thing was to see the white thighs of those Ba women when the two armies were fighting. The mixture of beauty and blood could stimulate people's nerves more than alcohol, especially among them, there was a tall chief's daughter, probably named Xian.

"Ye! Yes, she is..." Lu Gao didn't see Lu Cang's anger, and his body and mind were all in the small Lu Li mirror. He saw Xian mingling among the Ba people, holding a copper axe to chop the upper edge of his soldiers' shields. What she didn't know was that in order to deal with the Ba people's copper axe, a huge iron border was specially added above the Chu army's large shield, which was enough to deal with the Ba people's chopping.

"Put armor! Get armor for me quickly!" Lu Gao threw down Lu Lijing and shouted, all the left and right were inexplicably.

"What do you want?" Lu Chuang didn't understand what he wanted.

"Snatch a concubine!" Lu Gao, who was helping his servants, said without hesitation that he wanted to steal a woman. He fully understood how the Chu army fought today. Once the Ba people were exhausted, they would be suppressed by their own side. At that time...

"Let it go!" The artillery guards behind him began to bombard the guns as planned. When they heard the sound of artillery, Lu Gao moved even more urgently. Before he could put on his skirt armor, he led his private guards to rush forward. Lu Chuang shook his head helplessly and led people to follow him.

‘Boom-!’ As the cannon sounded, the enemy launched a large reinforcement. The Ba people who were in the fierce battle were inevitably at a loss. Most of them were afraid of artillery. When the cannon sounded, even though the shells had not fallen, they were worried that they would be hit by the shells.

"Switch!" Taking advantage of the situation of the Baren, the commander of the pawns rushed to give the order to change the formation. Chu Zu, who was raising his energy in the back row, just held a big shield and collided with his exhausted enemy, and retreated step by step. Taking advantage of the enemy's retreat and losing its center of gravity, he thorned the short sword in his hand, causing the Baren's front to shrink inward.

Linear tactics are different from spear formations. They do not destroy the enemy but kill the enemy. The enemy will be dispersed to the first level. The Chu army, who replaced the people, only suppressed the Ba people and did not defeat the Ba people. What really made the Ba people nervous was the landing point of the shells. The shells fired by the enemy's artillery soldiers all fell at the corner of the valley, and the trees, earth and rocks were smashed by the shells.

Although this does not hurt them in the battle, they can cut off their comrades' reinforcements and their own retreat. The point behind is particularly terrible. Fighting without a retreat is always frightening. This is exactly Lu Gao's plan. At the beginning, if you don't fire a cannon, you want to lure the Ba people out. After you lure it out, you can block the retreat with artillery, and then you can increase your troops and completely kill the defeat. It's easy to kill the defeat. At this time, if you let it go, the Ba people will naturally flee behind you and take the Ba people in the rear to escape together.

The Ba people were not good at defense, and placed the Ba people at the corner of the valley, which meant that the Qin people below the mountain pass did not care. The mountain pass was the key point of heavy defense. They could rush the defeated Ba people to the mountain pass and take a hundred steps, just to complete the order of Chengtong. Lu Gao calculated everything, but he didn't count that the Ba girl would appear on the front line. She was the daughter of the chief. Could it be that his father was killed by the Chu army?

The enemy formation loosened, and the brigade led Lu Chuang to personally lead reinforcements. The Chu soldiers on the front line shouted, and they had already attacked the Ba people's formation completely regardless of the front line. The exhausted and panicked Ba people could not defend themselves from breaking through the array and detoured behind them. Some Ba people fled, although shells fell like raindrops at the corner; others were unable to retreat, half surrounded by Chu soldiers, and were dragged back, and they could not retreat even if they wanted to retreat. Finally, they were surrounded by the Chu army. Xi Xian, protected by a group of men and women, was among the surrounded Ba people.
