Thousands of rebel camps were frozen in the sea of ice, like hard rocks, and there was no intention of retreating from beginning to end.

Yan Lie let out a long sigh, "It seems that today's battle is inevitable!"

"It's not that it's inevitable, it's that we're going to win. Yan Feng said excitedly, clenching his fists, "To win beautiful!"

Yan Lie looked at his son who was a little too out of the box solemnly, and admonished: "The battlefield is not a child's play, now that you are the commander of the Shence Army, you are even more responsible for the rise and fall of the imperial court, you must not act rashly!"

Yan Feng shook his head, "Father, until this moment, I haven't felt scared at all. I'm only now realizing that I was born for war. Even if I die today, I will live very quickly, and I will not regret it at all!"

Yan Lie looked at this excited son and hammered his forehead with his fist. This mischievous son inherited his youthful courage and ruthlessness, and he doesn't know if it's a good thing or a bad thing.

"Order, Dali Temple Qing has arrived!" a voice came from afar.

"Order, Dali Temple Qing has arrived!" the voice seemed to be a little closer.

"Order, Dali Temple Qing has arrived!" the voice was close to the city gate.

There were constantly soldiers shouting and giving orders, and they were all in touch, and the news of the imminent arrival of Liu Yu, the secretary of Dali Temple, was transmitted to the city tower where Yan Lie was personally stationed.

Yan Lie didn't care about the heavy armor on his body, and walked down the city tower quickly with his son to welcome the arrival of Dali Siqing.

The soldiers guarded the city wall for six days, and they had long been eager to see through this savior of Chang'an City. They stood at the head of the city, in the watchtower, and under the city walls, and they all focused their eyes on a horse galloping on the official road.

Liu Yu rode a red-maned horse, rarely put on full-body armor, galloped under the gaze of tens of thousands of Tang troops, and finally turned over and dismounted in front of Yan Lie, Yan Feng's father and son.

Behind him, one cart after another. The convoy was personally escorted by the three provinces of Hubu Shangshu and Liu, and the car was filled with iron chains, which weighed tens of thousands of catties, and the tired horses and mules who pulled the cart were panting and humming, and the hoof prints under their feet were very deep.

After all the convoys in Liusan Province arrived, they were followed by a convoy escorted by Pei Yuan, the secretary of the Ministry of War. The carts contained firewood and grass for unknown uses, as well as barrels of sealed kerosene.

Liu Sansheng and Pei Yuan came over to see Dali Siqing, Pei Yuan looked at the barrels of fire oil, his face couldn't help shaking, and said: "Lord Liu, this is the last inventory of our military department, you have to save some use!"

Liu Yu laughed, "It is not easy for Pei Shangshu to raise materials, and he is quite grateful in his heart. He saw that Liu Sanxing's face was a little unhappy, and he hurriedly said: "Liu Shangshu has made a great contribution to building this 60,000 catties of iron chains, which makes me very admired!"

Liu Sanxing felt comfortable after hearing his words, and a smile appeared on his face, "Which dare, which dare, it's just to serve the imperial court." As long as Dali Siqing gives an order, even if he goes to the knife mountain and the sea of fire, he will not hesitate to do so!"

Pei Yuan, the secretary of the military department, glanced at Liu Sanxing, and said to Liu Yu: "Lord Liu, this time you have lost all your old capital, you have to take some responsibility!"

He stretched out his hand and pointed into the distance, only to see that behind the carts loaded with firewood, grass and oil, there were countless cattle, donkeys, mules and horses, and other livestock, as many as a thousand.

Liu Yu was overjoyed when he saw it, and said loudly: "With these things, I will wait for today's victory to be decided!"

He didn't stop doing anything, and immediately arranged for everyone to divide the work.

In less than half an hour, the thousands of oxen, horses, and mules each pulled into a cart, which was filled with firewood and grass drenched with fire oil, and with sharp knives mounted on the axles on both sides. Strangely, there are also four chains placed inside each cart.

Seeing this, Yan Lie seemed to have an understanding in his heart, and asked, "Lord Liu, are you going to emulate Tiandan's Fire Bull Formation during the Warring States Period?"

Liu Yu smiled and nodded, "That's right!"

Yan Lie frowned, "But the ice is slippery, these livestock are estimated to slide to a large area as soon as they leave the city, and they can't become any climate, unless they ......"

His eyes suddenly fell on the hooves of the animals, and he found that all of them were equipped with a strange style of horseshoe, "This is also a horseshoe?"

"Yes, there are spikes under the horseshoe, so they can be non-slip on the ice! In addition, the military department has prepared a pair of non-slip espadrilles for each soldier, which will be delivered soon. Liu Yu nodded.

These non-slip horseshoe and espadrilles were secretly made and made by him to Pei Yuan using materials from the warehouse of the military department, so that they could come in handy today.

As for letting the Shence Army guard 300 blacksmiths to build chains in the houses north of the city, it is just a means to hide people's ears. But even if it's a means, it's still useful. In this regard, Liu Yu has already made arrangements.

"The humble official immediately ordered all the soldiers to change into espadrilles, so the reason why the Bahe River outside the city burst its embankment was intentional on the part of the adults?"

The reason why Dali Siqing ordered him to guard the city gate was to wait for the weather to become cold.

The weather is suddenly cold, the Bahe River bursts, the ice outside the city, and the non-slip horseshoe, linking these four things together is a big plan, and all of this is under the control of Dali Siqing.

Yan Lie looked at the Dali Siqing in front of him, only to feel that this twenty-three-year-old young man's heart was unfathomable, which made him feel a little scared.

Liu Yu gave an order, the war drums beat on the head of the city, and the Chunming Gate slowly rose. Many people drove thousands of cattle pulling carts to the city gates.

The rebel camp reacted quickly, and the leader Huang Chao quickly organized more than 600,000 horses close to Chunming Gate after hearing the war drums on the head of the Tang army.

Due to the slippery ice surface, these soldiers of the rebel army dismounted one after another, lined up into a fish-scale formation used in foot combat, and formed a phalanx of more than 600,000 people, each protecting six large chariots that looked like behemoths, and slowly approached in the direction of the Chang'an City Gate.

On the Tang army's side, it was just a cup of tea, and more than a thousand cattle pulling carts soon poured out of the city gate, standing in the cold and bleak autumn wind in the wilderness outside Chang'an City.

Liu Yu stood at the head of the city and gave orders, and the people under the city quickly took off the four iron chains from the carts behind the livestock as if they had been rehearsed, and tied them to the surrounding carts in one place.

These chains are not only soaked in fire oil, but also wrapped around all kinds of sharp blades, making them as difficult to reach as thorns.

But in an instant, a thousand carts pulled by livestock formed a huge array through iron chains.

The horn sounded, and the people lit the firewood and grass in the cart with fire folds, and the fire spread rapidly along the oil on the iron chain, burning into a sea of fire. The thousands of animals pulling the cart couldn't stand the heat behind their butts, and screamed and rushed in the direction of the rebel array.

At the same time, Yan Feng, who had been waiting at the gate of the city, finally got the military order passed down by Dali Siqing, and led 20,000 Shence army cavalry to rush into the cold wind outside the city.

Yan Lie looked at the raging fire in front of him, took a deep breath of the cold air in late autumn, and felt extremely comfortable in his heart. He pulled out his saber with a bang, and it was not until this moment that he really found a happy way to live his own life.
