When Sun Ying saw the rockets shot from a distance, he was secretly surprised. In just a quarter of an hour, Fulong Pass was lost. Has the Tang army prepared sufficient siege weapons? It seems that he can only count on the giant wood formation three miles away to block a Tang army's charge.

Three miles away, hundreds of big trees fell on the official road in a row, completely blocking the official road. There was only a three-foot passage at the edge of the backing mountain. This was the escape route of the Zhou army in Fulong Pass. Dozens of soldiers poured tinder oil over the big tree. At this time, a rapid sound of horse hooves came from a distance, and two hundred Zhou soldiers fled. A mile away from behind, Li Xuanba took the lead and led hundreds of Tang cavalry to chase him.

A soldier rushed forward and shouted, "Go from the side, there is a passage!"

The cavalry team immediately narrowed, and the cavalry rushed through the narrow passage one by one. At this time, Li Xuanba had already reached two hundred steps away. The last soldier ran through the tumbling wood. The soldiers were ready to move several big trees over and block the uppermost passage. A soldier lit the tinder of the big tree at the same time. The flames suddenly ignited and spread rapidly, igniting more than a dozen big trees on the outermost side first.

At this time, Li Xuanba arrived. His war horse was afraid of the fire, and he retreated and kept screaming. How could he not rush forward? Li Xuan was so doomed that he had no choice but to curse.

While retreating, the Zhou soldiers kept moving big trees to block the passage. The soldiers also began to set fires. Hundreds of big trees covered the road more than a hundred feet in a row. In just a moment, the raging fire engulfed the official road that was hundreds of feet long. The smoke filled the sky and the flames were everywhere. Even the shrubs on the mountains on both sides were ignited by the fire.

Soon, Changsun Shunde led a large army to fight. The scene in front of him stunned everyone. They stood hundreds of times, watching the fire dragons rage in front of him, and a fire ignited on the mountain.

"Strange, what's going on?"

Changsun Shunde began to be confused. The army just now was actually cavalry, but the defenders of Beidi County did not have cavalry. What kind of army is this?

The fire was not gradually extinguished until noon, and the fire on the mountain was extinguished because it did not affect the woods. The mountain was bare and black, which was shocking.

At this time, Li Shimin also led an army of 10,000. He was shocked when he heard that the road to the north was blocked by a fire and urged him to come forward to observe the situation immediately.

At this time, hundreds of Tang soldiers were cleaning up the big trees that had been burned into coke, tied them directly with iron chains, dragging them into the valley and river next to them.

Changsun Shunde reported to Li Shimin: "The brothers have no casualties at present, but have only delayed their trip for half a day."

Li Shimin frowned. Who was the other party? What's the point of doing this?

At this time, General Qin Qiong whispered: "Your Highness, I think that this is only one purpose, which is to delay time."

Li Shimin suddenly woke up and looked at Changwu City that was faintly visible in the distance. He was even more confused. Could it be that the army in Changwu City was not the Tang army?

In fact, Li Shimin considered this issue. The Zhou army closest to Beidi County is in Yan'an County. If the Zhou army from Yan'an County comes to Anding County, even if the defenders of Shangjun and Beidi County cannot resist it, there will be beacons coming.

Of course, if a surprise soldier of more than a thousand men went south, the defenders of Beidi County and Shangjun did not necessarily know, but what is the point of doing so?

It was because he thought that the Zhou army was meaningless to do this that Li Shimin did not consider that the Zhou army would come, but if it were not for the Zhou army, who would it be? Could it be that the Tang army of Beidi County surrendered to Li Yuanji and was ordered to block himself in Anding County?

Li Xuanba next to him shouted impatiently: "I guess it's nonsense! You'll know who it is after you hit it?"

Everyone laughed, and it was true that this was true. Li Shimin smiled and said, "The third brother is right, don't guess, clear the road quickly."

Soon, hundreds of big trees burned into coke were pushed off the cliff by Tang soldiers. They laid another layer of soil, which made the soldiers unable to feel the scorching heat of the land.

With the order of Li Shimin, the army continued to advance and rushed towards Changwu City three miles away. However, when Changwu City was still one mile away, Li Xuanba suddenly pointed at the flag on the top of the city with a sledgehammer and shouted: "Second brother, what kind of flag is that?"

Li Shimin also saw it, and his heart sank. The big flag fluttering in the wind was clearly the black dragon and red flag of the Zhou army.

On the official road north of Ding'an County, Beidi County, a cavalry composed of 5,000 people rushed south quickly under the leadership of General Luo Shixin. After receiving the emperor's order, Luo Shixin immediately sent troops south. In order to gain time, Luo Shixin's troops were divided into two groups. He personally led 5,000 cavalry first, and then general Sun Changle led 20,000 infantry to go back. Each soldier only carried five days of dry food, tried to streamline equipment and facilitate marching.

When the cavalry team passed by Ding'an County in a mighty manner, Luo Shixin ordered the soldiers to shoot a letter to the city. The army then bypassed the county town and continued to march southwest. The emperor gave him the order to kill Changwu City before dark. It was noon now, and there were still 120 miles away from Changwu City. As long as you seize the time, you can basically complete this task.

But Luo Shixin was also worried that the defenders of Changwu City could not support him. He did not wait for the reply from the garrison of Ding'an County, but the army continued to advance.

Ding'an County is the county seat of Beidi County. There are 5,000 Tang troops stationed in the city. The main general was Wei Song. He was born in the Jingzhao Wei family and was of the same clan as Wei Yunqi, the Minister of the Great Zhou Dynasty. His official position in the court was the General of the Central Army, but Li Shimin also appointed him as the General of the Cavalry of the Tiance Prefecture. At this time, Wei Song stood on the top of the city and watched the five thousand Zhou army cavalry head southwest along the official road.

Wei Song didn't know that Changwu City had fallen into the hands of the Zhou army, but he knew that the Zhou cavalry must be heading for the King of Qin. His premonition was getting stronger and stronger. The final decisive battle was about to begin, and the letter in his hand proved that his premonition was correct.

The letter reads: "General of the Right Guard of Zhou, Luo Shixin, Duke of Song, to General Wei Song." It turned out to be a letter written by Luo Shixin. Luo Shixin was among the five thousand cavalrymen. Wei Song certainly knew that Luo Shixin's position in the Zhou army was ranked first. General of the Right Guard, and Luo Shixin personally led his army south, which means that a major battle will take place.

"General, what should we do?" a general next to him asked in a low voice.

Wei Song looked at the letter, which said that if he was willing to surrender to the Zhou army, tens of thousands of troops would arrive soon. He could surrender to the rear army. If he was unwilling to surrender, he would also ask him to remain calm.

Wei Song sighed and said, "Don't act rashly for the time being, look at the situation before talking about it."

Several generals agreed that if a little wrong step is taken at this critical moment, their destiny will be completely changed. Being cautious is the king.

The bloody battle in Changwu City has been going on for nearly two hours.

The terrain of Changwu City is slightly higher, with a gentle slope from bottom to top, about 300 steps long. At this time, the slope below the city west seemed like hell, and the ground was burned to black. Hundreds of soldiers who had no time to withdraw from the first attack were killed in the sea of ​​fire, and their bodies were burned to black charcoal.

The second and third attacks also left countless corpses. The slopes were covered with corpses, and dozens of broken ladders fell into the soil, but more were soldiers who died in battle, with more than 2,000 people.

Some were curled up by the fire, and their bodies were beyond recognition. Some were pierced by spears, their faces were filled with temporary pain, some were missing heads, and some were incomplete.

Everything was shocking. Even Tang Jun himself was unwilling to attack in Xicheng, but moved the battlefield to Beicheng.

In fact, Li Shimin could have gone around the city and rushed directly to Chang'an, but Li Shimin saw that there were only more than a thousand defenders on the top of the city. If he couldn't even take down this small city, it would seriously affect his credibility.

More importantly, Li Shimin's dignity made him unable to turn a blind eye, and he had to take down this strong city.

Li Shimin waved his sword and said, "Transfer my order, and the army will attack again!"

The Tang army's attack began, and the fierce drums sounded again, and another three thousand Tang army entered the siege battle. This was the fourth siege.

A long siege ladder appeared, and red flags flew on the city. The chief general Sun Ying issued an order to go up to the city. Five hundred soldiers preparing for war in the city rushed to the top of the city and joined the fierce battle.

The Tang army under the city organized 5,000 crossbowmen to cover the army's attack. The arrows were like rain, shooting towards the top of the city, which made the Zhou soldiers unable to raise their heads. Zhou soldiers were constantly shot and fell from the top of the city screaming.

With a loud bang, gravel splashed everywhere, and a siege ladder mounted on the north city. Then more than ten siege ladders mounted on the city wall one after another. Thousands of Tang soldiers rushed up like ants, chopped with knives, stabbed with spears, shot with arrows, and rushed to the city wall desperately.

The rolling wood and stones on the city were smashed like hail, and the sword slashed the spear, and the flesh and blood flew everywhere. The Zhou army soldiers used the steel fork to defend the city to cross the ladder and pushed it outward. A long siege ladder was pushed out and turned backwards down. A terrifying shout came from the ladder.
Chapter completed!
