The Jinguang Gate of Chang'an City was within Ye Chang's line of sight, but before, he would not use a telescope to observe this gate, but now it is not, he is ten miles away from the Jinguang Gate, looking at the capital of the Tang Dynasty from a distance.

Bian Ping looked a little lonely, standing beside him, and didn't dare to say a word.

Putting down the binoculars, Ye Chang calmly turned to face him, and when he saw that he was still like this, he couldn't help laughing: "Still unwilling?" ”

"I'm really unwilling, I always feel that I could have decided it in one fell swoop." Bian Pingdao.

"Do your business, don't be in a hurry, and don't think about making a decision in one fell swoop, you must know that these means, after all, are only auxiliary, you can have the first merit, but you can't have the whole merit. An Lushan, a mixed beard, can steal a high position, is it a fluke! Therefore, it is also a matter of duty for you to be driven out of the city if you have no foothold in the city, and why I asked you to make a plan to retreat when the worst is to know that this will be the case. ”

Ye Chang patted Bian Ping's shoulder and comforted the guy in charge of intelligence.

After An Lushan decided to join forces with Shi Siming again, he immediately began to purge the hundred officials in Chang'an City, since he had made up his mind to return to Fan Yang, he naturally no longer had scruples, and all the slightest suspects were arrested, although Bian Ping was meticulous, but he could not face this situation of preferring to kill three thousand by mistake rather than let go of one, fortunately, he had been advised by Ye Chang beforehand, and if there was a discord, he would evacuate immediately, so the loss suffered was not too great. But he had planned to have the officials in the city who were secretly in contact with him surrender the city, but this plan was completely ruined.

Seeing that he was still a little uneasy, Ye Chang said again: "You have done a good enough job, you have to leave some credit for others...... There is another thing, you should pay attention, you contact those in the city who have not yet been exposed, and ask them to pay attention to the protection of Chang'an City. ”

"Lang Jun is worried that An Lushan's dog will jump off the wall in a hurry?"

"That's inevitable, if he can't keep Chang'an, how can he leave us such a good city? Ruining Chang'an can distract me to some extent, and if he concentrates on escaping, he may be able to use this to stop me. ”

"Yes!"

After instructing this, Ye Chang didn't say anything else, he turned back to the barracks and ordered to seize the villages on the outskirts of Chang'an City. An Lushan only symbolically defended these villages, then set them on fire and abandoned them, and the whole army retreated back into Chang'an City.

Bian Ping followed Ye Chang's side and saw that although he was dispatching troops, he was only arranging a siege and did not really start to attack the city. He was a little puzzled in his heart, could it be that Ye Gong wanted to fight a protracted war with the thief?

But he quickly overturned this speculation, because Li Longji's envoy came again.

It's still Zhou Xiangren, his face is full of wind and dust, seeing Ye Chang, he gave a deep salute: "Ye Gong, the sage heard that Ye Gong asked him to prepare to return to Beijing, and sent slaves and maids to spread the word, Ye Gong must not change his plan because of the sage, and should cherish the soldiers first." ”

Ye Chang smiled slightly: "I know the way, since this is the case, you can rest in our army for a few days, and then go back to the saint after watching me break the thief." ”

He sent Zhou Xiangren away with a word, but Bian Ping heard Ye Chang's determination and confidence from it. Ye Chang is clearly absolutely sure that he will be able to break through Chang'an City in a short period of time, since this is the case, then it is impossible to fight a protracted battle with An Lushan.

Sending Zhou Xiangren away, Ye Chang looked at Bian Ping, and said with a smile: "Come with me to meet Xin Jinghao and Yue Xi, the two of them played well in Tongguan." ”

"They've arrived?" Bian Ping said in surprise.

Ye Chang smiled, this guy will also play tricks now, he is in charge of intelligence investigation, how could he not know that Xin Jinghao and Yue Xi are already in the east of Chang'an City, and they have seized the Baqiao and pointed to Chunming Gate.

As soon as Xin Jinghao saw Ye Chang, he immediately bowed down: "Jinghao meets Ye Gong!" I haven't seen him for a few months, is Ye Gong well? ”

"Haha, get up!" Ye Chang pulled him up with a smile: "Jing Hao, you played beautifully in Tongguan!" ”

"It's Ye Gong's clever plan, it's just an executor, anyone can win!"

This guy is humble, but he just called Ye Chang Ye Gong and called himself Jing Hao, which has a lot of meaning.

"Yue Xi, now you know that military affairs are not easy, right?" Ye Chang looked at Yue Xi with a smile again.

Yue Xi's face was ashamed: "Lang Jun is right, now I finally understand why Lang Jun didn't lead the troops with me." ”

Yue Xi is a bit of a military talk on paper, Ye Chang put him on the road construction site for a long time, let him train road construction workers with military methods, originally wanted to increase his practical experience, to help him grow into a civil and military all-rounder, but he trained workers successfully, for his military talent is more conceited, until the battle of Tongguan, thousands of troops and horses, he found that he still took it for granted, the most prominent is the kind of siege explosives he invented, in fact, the effect is not great.

And if it weren't for luck, it would not have been possible to blow up the gates of Tongguan.

"Are you all invited?" Ye Chang asked after a cold talk with everyone.

"It has been selected from the army, one thousand two hundred, ready to come in handy, and there are two thousand people on standby!"

"Good!"

Hearing this news, Ye Chang was overjoyed, he looked at Yue Xi, nodded and said, "It's really good that you can eat a trench and grow wise." That being the case, I will entrust you with the task of completing it within three days—do you have a plan? ”

"There is already a belly case, just waiting for Lang Jun's approval!"

They spoke like a dumb riddle, and Bian Ping was confused, but soon, he figured out what was going on.

Since Chang'an City is the capital of the Tang Dynasty, it is naturally one of the best fortified cities, although strategically speaking, after Tongguan was lost and surrounded on all sides, there is no point in defending the lonely city of Chang'an, but if An Lushan and Shi Siming want to live and die with Chang'an City, if they want to capture this city, it will not only take time and energy, but also cause great damage.

The people in the city will not survive even more!

Therefore, Ye Chang did not plan to attack the city with ants, his plan was very clear, since gunpowder could blow up the Tongguan city gate, then it could also blow up the Chang'an city gate.

It's just that with the lesson of Tongguan, An Lushan must be prepared, and it will not be easy for gunpowder to approach the city wall, and it may have to pay huge casualties.

Therefore, Ye Chang had already planned to let Yue Xi prepare the miners.

In the Luoyang army led by Xin Jinghao and Yue Xi, there were originally more than 20,000 workers recruited from the vicinity of Xiuwu, many of whom were miners who were good at drilling holes and digging pits. Yue Xi selected 3,200 of them, and then prepared sufficient tools to facilitate the capture of villages near the city wall outside the north and east gates of Chang'an, and dig holes in private houses to dig tunnels.

At the same time, trenches were also dug outside Chang'an to cover up a large amount of earth and rock, making preparations for a long-term siege of Chang'an.

3,200 workers took turns to dig, Chang'an is surrounded by plains, the soil is easy to excavate, so the progress is very fast, only three days, the tunnel through the moat, to the city of Chang'an.

In Chang'an City, Shi Siming, who was in charge of guarding the east gate, had a gloomy face, walked under the city wall, and looked at the vats: "How is the movement?" ”

"It's getting louder and louder, not far from the city walls!" The soldier who was in charge of listening next to the vat reported.

The Tang army built a lot of buildings, dug trenches and dug ditches, although they covered up their purpose at the beginning, but the next day, Shi Siming found out that something was wrong, let people dig a pit in the city, put a few large vats upside down in the pit, and let the soldiers with outstanding hearing listen all day long, and sure enough, he heard the movement, and he immediately judged that the other party was preparing to attack!

In the era of cold weapons, attacking cities and cave attacks were not uncommon, Shi Siming had his own countermeasures, he first ordered the listening soldiers to judge the direction of the tunnel excavation, and then dug a trench horizontally in the confirmed direction, and then ordered the soldiers to monitor day and night. No matter how well the Tang army can dig tunnels, it is impossible for the Tang army to rush into the tunnels together, and in the end they will still drill out one by one, and then his subordinates can catch turtles in the urn.

This kind of response is decent, and everyone has done this in the art of war since ancient times. Shi Siming didn't feel at ease when he thought about it, so he asked people to prepare firewood and grass, and if the wind direction was right, he was also ready to make a smoke fire.

Since there is an abnormal movement in the Tang army on his side, how can there be no one on An Lushan's side! An Lushan is now lacking in energy, and it is impossible to personally command the defense of the city, Yan Zhuang, a scholar, can make plans and conspiracies, but it is not easy to really take charge alone. Therefore, Shi Siming also sent people to warn, and An Lushan also sent people to thank the labor army, and the relationship between the two sides became a little closer because of this.

"Now that I've been under the city walls, I've been here for the past two days." Shi Siming muttered.

"It's not bad to be able to frustrate Ye Chang's sharp spirit first." Liu Luogu said with a tired face.

"What you asked you to inquire about, but has it been settled?" Shi Siming asked.

"There are some eyebrows, and someone told me that His Royal Highness the Crown Prince secretly ordered fires to be arranged all over the city to send the dead to guard them." Liu Luogu said: "Looking at the situation, His Majesty has prepared for the worst, if the city is really breached, he will definitely set fire to the city." ”

"What kind of prince is Your Majesty, so far, you still don't dare to talk about him!" When Shi Siming heard the news, he first complained that Liu Luogu still didn't forget the old feelings, but then his eyebrows rose: "That is to say, An Lushan is not even the slightest sure about guarding Chang'an City, he is unwilling to hand over an intact Chang'an to Ye Chang, and he has made up his mind to destroy Chang'an...... No, he's going to run! ”

"Didn't Shi Gong say a long time ago that he was going to flee back to Fanyang?" Liu Luogu was a little unimpressed.

"No, he's going to run away in a day or two!" Shi Siming took a breath of cold air, cursed a few words, and then said sharply: "You immediately want to pass the news to Ye Chang, just say that An Lushan is going to take our backs, and he will set fire to escape!" ”

"What?" Liu Luogu was shocked.

He did have a way to get the news to Ye Chang, but the two sides were mortal enemies, what was Shi Siming's purpose in doing this?

"I will tell An Lushan that I leaked the news to Ye Chang, and let him do it himself." Shi Siming said with a smile: "Since he has a way to get out, he doesn't want to dump us, he wants to die together, and he wants to live together!" ”

After understanding what he meant, Liu Luogu had no choice but to smile bitterly.

After An Lushan and Shi Siming turned their backs, they lacked the least trust between each other, and both sides were afraid that the other party would stab them in the back, so they restrained each other. Although they are no longer fighting on the surface, they are secretly on guard.

Thinking of this, Liu Luogu couldn't help but be discouraged, it was precisely because he seized the opportunity of Li Longji, Yang Guozhong, Li Heng and others to contain each other, so that An Lushan was able to raise things, but now, on their side, they pulled each other back.

Although I was unwilling, I had to do it. Shi Siming passed the news to An Lushan, An Lushan was summoning Yan Zhuang to inquire about the traitors in the city, and after hearing it, he was so angry that he couldn't control it anymore, not only kicked Yan Zhuang in the head, but also directly ordered: "Cut this person down!" ”

Yan Zhuang was frightened, almost urinating, when the warrior came up to clamp him, An Lushan said again: "It's not Doctor Yan, it's this guy!" ”

He was referring to the messenger sent by Shi Siming, who immediately panicked and shouted for mercy, but An Lushan was unmoved, and ordered the warrior to cut it off and throw his head directly into Shi Siming's territory.

Yan Zhuang, who had escaped for his life, wiped his sweat and said tremblingly: "Your Majesty, what should I do now?" ”

"Shi Siming's guy really deserves to be my best friend for many years, if he really understands my thoughts, he must have found clues, and he knows that I want to leave Chang'an, so he threatens me with this, so that I can take him with me!" An Lushan sneered: "It's just that he knows me, how can I not know him!" I cut down his messenger, and he thought I had nothing to do to kill and vent my anger, but he didn't know my true intentions! Now that we are ready, he just revealed the news to Ye Chang, and Ye Chang didn't have time to lay out...... Ye Chang's idea, how I don't know, Shi Siming only said that he wanted to dig a tunnel to attack the city, but I knew that he must have buried the gunpowder under the city! ”

"What!" Yan Zhuang screamed, and then suddenly realized: "This ...... In the past few days, Ye Chang has not attacked the city, but only dug tunnels, which turned out to be to bury gunpowder? ”

"If the Chang'an city wall and Tongguan are generally blown down, how can this city still be defended? I had expected this, so I wasn't prepared to defend it! Ye Chang's attack, it must be in the night of the next two days, he only said that we have not been able to see through the plan, in order to be able to do our best in one fell swoop, we must be arranging the siege now, the whole preparation is completed, the most likely is tomorrow night! I'll break through the siege tonight, leave a burning Chang'an and him, and see if he wants to save Chang'an or my life! Based on my perception of Ye Chang, he must feel that I am now a lost dog, unable to escape his palm, and reduce losses as much as possible, so I must give priority to fighting fires. And there is still Shi Siming in the city, he has to eradicate Shi Siming first before he can put out the fire with peace of mind, and only after he has put out the fire, can he chase me! ”

Yan Zhuang swallowed his saliva and looked at An Lushan, not knowing whether to admire or despise Dao.

After all, An Gong was tortured by injury and illness, and his energy was low, although he was vicious as always, but when he thought about the problem, he couldn't help but take it for granted.

Since Ye Chang has so many designs, how can he be so easy to be broken by him? And Shi Siming and Chang'an City, how long can they stop Ye Chang?

"Have you packed all your things?" An Lushan said again: "Don't bring those bulky things, burn them tonight, only bring gold and silver, I will only give you two hours, you must do it today!" ”
