The further you go, the thicker the log is used to support this dark passage, and occasionally you can see the tuyere of the round hole, and I don't know where it leads. Each vent has a rope hanging from it, which is the cable used to pull the outer lid open. I could hear the wind whistling, that is, the wind outlets along the way had been opened by Xiao Ping, and the fresh air was constantly blowing into this long dark passage. I don't know how long I walked, and suddenly Xiao Ping behind me whispered: "Be careful, it's almost there!" ”

Jerub was startled, slowed down, and walked a hundred and ten steps further, and came to a place where he suddenly opened up, and unexpectedly dug a huge dark chamber in the ground, which was enough to gather more than four or five hundred soldiers. On one side of the wall of the dark room, there is another hole in the secret passage, leading to the east city wall not far away, this section of the foundation has already been hollowed out, all supported by several people hugging the thick giant trees, as long as these huge trees are destroyed, and then shaken by the explosion of gunpowder, the city wall will collapse immediately.

The exit of the secret passage was originally a neighborhood inhabited by Han Chinese, and after the people were forcibly taken into slavery, they were vacated as a forage field for the army. Whether it was the Liao army or the Jin soldiers, the army used a lot of horses, even in the city, feeding horses also needed a lot of forage, and most of the courtyards and houses in the neighborhood were full of forage. Forage is not as important as food, and there are golden soldiers guarding the outlying places and the entrance of the neighborhood, mainly to guard and set fire to the forage. The further you go inside, the more inaccessible it becomes, and only the inner Ying placed by the King of Jin is waiting on it.

Nei Ying looked quite nervous, and ran outside to look at it for a while, and then turned back again, watching the palace tent army crawl out of the tunnel one by one. Soon, the small courtyard where the secret passage exit was located was already crowded with people, and Yelubo arranged for the centurion on duty to take the soldiers who came up first to hide in the adjacent courtyard. More than 4,000 palace tent troops came out of the secret passage one after another, scattered in dozens of courtyards nearby, and the Jin soldiers on the periphery never noticed. Yelubo breathed a sigh of relief, this is Changshengtian helping the Khitans, he is sure in his heart, even if something goes wrong under the city wall, with these thousands of strong soldiers, it will not be a problem to capture a city gate.

The thick giant wood supported the hollowed-out foundation, and the Liao soldiers lit the oil of fire, and the wood burned violently and made a crackling sound. The smoke drifted out along an oblique upward air duct. Xiao Ping stood not far away, looking nervously at the underground fire. He was followed by more than a dozen palace tent sergeants, all holding their breath. Everyone's cheeks were smoky and charcoal-colored, and the fire made their clothes and armor seem to burn, and there were beads of sweat on their cheeks and backs, and the air they breathed was gradually running out of enough. If the city wall collapses after this fire, they will definitely be buried alive. The timber burned very quickly, and the structures supported under the base of the wall were quickly burned to pieces. Maybe after a heavy rain, maybe a few really huge stone bullets, this seemingly impregnable wall would collapse like a papier-mâché floor, but for now, it still looks as stable as Mount Tai.

The Jin soldiers at the head of the city did not have any abnormal feelings, some were patrolling back and forth, some were sitting and lying behind the battlements with bows and arrows, and some were bored looking into the distance, smiling and betting on when the Liao soldiers would withdraw. After the battles of Ningjiang Prefecture, Huanglongfu and Shenzhou, the generals of the Jin army knew that defending and besieging cities was not what the Khitans were good at. "Look, there's smoke!" A golden soldier looking at the head of the city pointed into the distance, where black smoke wafted from various vents, which was particularly obvious in the blue sky. The centurion smiled: "There are only Liao soldiers left in this radius, could it be that they are burning the camp tents and preparing to escape?" The Liao army stationed near the tuyere also looked at the gushing smoke curiously, and the military order did not explain what was going on. After a while, the commander of the army gave another order, ready to get on his horse and charge! Prepare to storm Shenzhou City! These two completely marginal military orders, under the long-term and harsh training, the Liao army still carried out them to the letter.

"Let's light the fire." Xiao Ping said in a low voice, he and his subordinates carefully dug out the medicine primer, thousands of catties of gunpowder had already been buried nearby, and the vibration of gunpowder was needed to cause the city wall to collapse. Xiao Ping's eyes remained motionless as he watched the gunpowder primer sparkle and gradually burn into the ground, and he didn't know how long it would take to burn into the powder room. The Liao soldiers behind were already extremely nervous, and if these people had not climbed out before the gunpowder exploded, they were likely to be buried in the collapsed tunnel.

Several people seemed to hear their own heartbeats, and in less than a moment, as if a year was so long, they finally heard Vice General Xiao say: "Let's go up." Only then did he crawl out of the dark passage as if he had been pardoned. Yelubo was already waiting on it, and when he saw Xiao Ping, he asked, "How is it?" Xiao Ping nodded, patted the dirt on his body, and said in a deep voice: "Everything that needs to be done has been done." He has such a temperament that if he is not nine out of ten, he will never say anything full. If it weren't for that, the North Court wouldn't have let him take on the matter. Yelubo and Xiao Ping have been working together for more than a day, and when he heard this, he also nodded, and said in a low voice: "Just now, two Liao dogs came in to inspect and were hacked to death by us, I don't know how long I can hide, I ......"

He wanted to say that if the city wall could not collapse in time, he would seize the city gate, but suddenly he heard a muffled sound of "boom", and the ground trembled violently, and Yelu Bo said with joy: "It is finished!" He and Xiao Ping both looked eastward, the city wall still seemed to be unmoving, Yelubo sighed secretly in his heart, although His Majesty the righteous path had a clever plan, this matter of blowing up the city wall could not be completely controlled by manpower. He ordered all his troops to assemble and prepare to attack the east gate from inside the city, and to signal fireworks to General Xiao Chara outside the city. At this moment, the walls of the city, whose foundations had been hollowed out and the wooden structures that had supported them, had been burned down, collapsed almost without warning, like the sudden collapse of a man who had been standing for a long time.

Under the city of Liaoyang, in the camp of the Jin army, all the generals had grim faces, and Wanyan Di Gu Nai shouted loudly: "Why do you want to retreat, Your Majesty, as long as you let the warriors rush forward for a while, we can take out the iron barrel cannon of Liaogou and capture Yelu Dashi alive, I have already seen his sun and moon flag!" He gritted his teeth, his face was hideous, today, the warriors who were suddenly shelled by the Liao soldiers lost more than twice as many as those who were injured by arrows, and most of them were rushing to the front, the most elite Tiefutu. The two Meng'an were disabled, and since the Jin army raised its army, when has it suffered such a big loss. Although everyone was panicked at the time, now there is a lot of excitement. Iron bucket cannon is also common in the Jin military camp, and it is all relied on to fight Huanglong Mansion and Shenzhou. As long as you know the tactics of the Liao army and take precautions, it is not easy to suffer such a big loss today.

Most of the generals were silent and did not speak, and after Yelu Dashi arrived in Liaoyang, the Liao army seemed to have been reborn, showing unprecedented strength, which was what everyone cared about. There were two or three hundred thousand Liao troops in front of them, and there were hundreds of thousands of men and millions of people in Liao. In the Wanyan tribe, not everyone is only a brave man, but on the contrary, under the Meng'an Moke system, the generals who lead the troops are usually in charge of civil affairs, and all kinds of general affairs must be involved, and non-thoughtful people cannot serve the public, so most of the generals of the Jin Kingdom who can obey orders under the account of Wanyan Agu can see this, such as Wanyan Ci, Wanyan Zongbi and others, thinking about the long-term, are worried.

Wanyan glanced at the seat with his eyes, probably understood everyone's intentions, he sighed in his heart, at this time the Jurchen and the Liao army have presented a life-and-death situation, both sides are the royal driving and personal conquest, and they can't retreat easily, even if the Jurchen army wants to retreat, they must defeat the Liao army to keep it safe, otherwise, the Liao army is mostly light and fast horses, and it will be like maggots on tarsal bones, chasing after them.

"The top priority is still to restrain the artillery of the Liao State," Wanyan Agu said in a deep voice, "Defeat the Liao soldiers, what are the methods?" Out of the corner of his eye, he glanced at Zhao Xingde, who was sitting at the bottom, and the bell must be tied to the bell, Zhao Xingde is now the best artillery person in the gold camp, so he was invited to participate in the imperial tent military meeting that he had never participated in. I saw Zhao Xingde frowning, as if he was preoccupied, Wanyan Agu's gaze turned to Han Ningshuang's body, and then returned to Zhao Xingde, both of them are Han, one has a stubborn personality, although he grew up in the Wanyan tribe, he insists on maintaining the independence of the Han army. The other is the Xia people, what is incorporated into the Jurchen household register, out of the palm of Meng'an Mouke and the like, for ordinary Bohai people, ordinary Han people, it is an extra reward, for Xia people, it is a joke.

"What's the solution," Wanyan Zonghan said in a deep voice, "In my opinion, although the power of this iron barrel cannon is huge, after firing one shot, it takes too long to fill the ammunition, and today's distance of two hundred paces is only enough for the Liao soldiers to fire one more round, and then we can rush into the position of the iron barrel cannon." Then," he looked at the generals and saw that Zhao Xingde's eyes were slightly provocative, "My Jurchen is known for being an iron horse and a hard rush, as long as the warriors are not afraid of death, this iron barrel cannon is not protected by a city fortress, so there is nothing to be afraid of." He had a strong temperament, and he didn't notice that he faintly opposed his father's decision to temporarily withdraw troops today, which made Wanyan Aguda's face sink slightly, but Zhao Xingde smiled slightly and did not refute.

"It's not unreasonable to stick to Han's stupid method," Wanyan Agu's heart moved, and he asked Zhao Xingde: "What does General Zhao think?" Zhao Xingde's expression fell in his eyes, and he knew that the surname Zhao was unimpressed. Since the army was raised in Ningjiang Prefecture, in the past few decades, Wanyan Agu has become more and more cautious as he gets older, and every time he takes an idea, he must listen to the opinions of all the generals in the account, and repeatedly consider the pros and cons before making a decision.
