"Some trouble. Xie Yan said. "According to the news sent back before, we have a relatively clear understanding of the arming situation in Tongguan. However, if these 5,000 people join, the arming situation will inevitably change, and the time left for us will be very short, and there will be no time to make new deployments. ”

"Mo Zhi is right. Lin Ning said. Xie Yan was silent, and after getting acquainted with each other, Lin Ning commensurate Xie Yan with words, and seemed closer. "So I don't think we can let these 5,000 people into Tongguan. ”

Jiang Wei took a closer look at the terrain from Chang'an to Tongguan, shook her head slightly, and said, "The time is not very easy to control. If we want to intercept these 5,000 troops halfway, we have to attack before the Zhenbei army engages the Shu army, when the main force of the Zhenbei army has not gone far and may be killed at any time. We're going to be caught on both sides. ”

Xie Yan raised his eyes and glanced at Jiang Wei carefully, and said with a slight smile: "What the lord thinks should be to take advantage of the time difference in news transmission to wipe out all the five thousand reinforcements in the middle of the road, so that the Tongguan side thinks that the reinforcements have not yet arrived, and the main force of the Zhenbei Army thinks that the reinforcements have arrived in Tongguan safely." It's just that our army is so close to Tongguan, and Tongguan will definitely be aware of any move......"

Xie Yan raised his eyebrows and looked at Lin Ning, but found that Lin Ning still had an indifferent smile on his face, and he couldn't help but be stunned.

Lin Ning pointed to Tongguan and said: "We not only have to fight the time difference, but also fight psychological warfare." ”

Her hand began to draw the path of the additional troops from Chang'an, and said: "We will advance the time of attacking Tongguan, make the frontal battlefield a little bigger, and actually feint to preserve our strength." After the start of the war, the reinforcement of troops will inevitably speed up the march to Tongguan, and when they arrive here, they will inevitably camp, because there is no suitable place to camp after here. ”

"We're ambushing right here. She laid out the sand table of the terrain, and after a few discussions, they all felt that it was very likely to be completely annihilated.

"It's still that problem, as soon as there is any change in our place, Tongguan will send a message to the Zhenbei Army and the reinforcement of troops. Xie Yan always felt that there was a big loophole in this plan, and he didn't know why Lin Ning just turned a blind eye to it.

"So we don't move. Lin Ning looked at Xie Yan with a playful gaze. "Who said that it must be my Yanzhou army that ambushes and increases troops?"

"Could it be that the lord will still scatter beans and become a soldier?" Xie Yan sarcastically replied to Lin Ning.

Lin Ning smiled: "It's not possible to scatter beans into soldiers, but fortunately, we have allies." The war on the side of Bingzhou is over, and the 5,000 cavalry of the Xianbei tribe and the Tuoba tribe who have taken refuge in Youzhou have not yet made an inch, and they took the initiative to ask Xuan Che to come to support, which is so beautiful but disrespectful. ”

"No wonder...... The ambush location you choose is open and suitable for cavalry charges. Jiang Fei was silent for a long time before he spoke.

Xianbei was originally a nomad, and the 5,000 cavalry who came to support from Bingzhou were good at riding and archery, but because there was no room for cavalry to play much in the war in Bingzhou, while the ability was buried, the strength was also completely preserved.

The cavalry marched fast, cutting directly from the Sizhou border to the rear of Tongguan, and there was still time to rest for two days after coming.

"It turns out that the lord already knew that there would be reinforcements, and he deliberately hid it from us. Xie Yan accused Lin Ning of his bad behavior.

"The lord just wants to see how anxious you look. Jiang Wei knew too much about Lin Ning's bad nature, and pointed out the facts that made Xie Yan depressed.

The moon is dark and the wind is high, and everything is silent.

At the time of the third watch, a beam of sky-high fire suddenly rose in Tongguan City, and most of the red firelight could be seen in Tongguan City.

"The granary is gone!!" A mournful cry accompanied by a rush of gongs, after alarming most of the city, it was transmitted to the Tongguan Governor's Mansion.

The lieutenant of Tongguan, who was asleep, got up in his clothes, rushed out of the door, and shouted to the soldiers outside the courtyard: "What are you still doing in a daze! Come with me to the east of the city to put out the fire." ”

The soldiers responded in unison, took up weapons and torches, and rushed out of the mansion with the captain.

One of the personal soldiers holding a torch always followed the side of the Tongguan Commander, and under the firelight, he looked at the unarmored back of the Tongguan Commander, and a trace of sharp light flashed in his eyes.

West of Tongguan City. The patrol guards crossed one by one, and the two guards stopped at the intersection of the patrol lines, looking at the fire in the direction of the granary, their eyes full of worry.

"I don't know what the fire is, but if we really burn all the food we have, then we will have a hard time in the future. One of the guards whispered.

The Zhenbei Army was very strict in governing the army, and the guards did not dare to let the soldiers hear the conversation between the two of them, so as not to shake the morale of the army.

Another guard also lowered his voice when he heard this: "This water, the fire must be extinguished by cellar water and well water, and I am afraid that in the future, it will have to be river water." ”

"There's still no order for us to put out the fire?"

As soon as the words fell, a high-ranking guard came on horseback, ordered half of the guards at the west gate, and said, "Follow me to the granary." ”

The guards who had not left stood on the city wall, and when they saw that the defense near the west gate was much weaker in an instant, they couldn't help but feel a faint sense of unease in their hearts. He looked into the city, and suddenly saw a pillar of fire suddenly rising in the direction of the eastern city, and the sound of popping came after a long time, and the roots of his ears were numb.

"Dongcheng...... Not good! Armory!" The guard's face suddenly turned pale. The only thing that can be burned like this in the direction of Dongcheng is the armory, and the armory not only has non-flammable swords and armor, but also winter cotton clothes and bedding.

Although it was now wartime, every soldier was armoured and swordsman, so that some of the ordnance was spared. However, the military resources in the armory are still something that the Tongguan defenders cannot give up, and they must send someone to save them.

"Not true. A chilling fear struck him. It is certainly not a coincidence that the granary and the armory caught fire at the same time overnight, and it must have been a traitor in the Tongguan garrison.

Tonight's ignition of the granary and armory involves the forces in the city, with the purpose of ......

The guard turned and ran to the other side of the wall, and saw a burning rain of arrows falling from the sky like a meteor shower, reflecting the night sky in a fiery red.

"Enemy Attack !!"

The guard's hoarse roar pierced the sky, ending with a cluster of arrows passing through his throat.

Outside Tongguan City, Lin Ning stood on a high place and overlooked, only to see the firelight everywhere in Tongguan City, and the torches formed a long dragon to swim back and forth in the city. Outside the West City Gate, the catapults and crossbows of the Yanzhou army projected the weapons of harvesting life on the city wall outside the range of the bows and arrows of the Tongguan defenders.

"News came from the reinforcements from Bingzhou that the 5,000 additional troops from Chang'an had been wiped out at the ambush point. ”

After listening to the news of the pro-soldiers' loud report, Lin Ning's eyes did not have the slightest joy.

"Tongguan, didn't you say that it was just a feint, why did you change your mind in the end?" Xie Yan shivered in the evening breeze in a wide cloak, and looked at Lin Ning, who was still immobile in thin armor, and felt that her expression was becoming more and more elusive.
