"Ben does have an idea, but it's hard to say if it will work out, and it will take at least a month to get ready. www.biquge.info"Chai Zaiyong is a cheerful person, and when he saw the two of them asking, he didn't hide his selfishness and said in a deep voice: "When I was serving as an assassin in Gwangju, I saw these remnants of the Caizhou army running rampant in the countryside and killing the people. In addition, at that time, Jianghuai was initially decided, and the king did not want to cause more trouble in order to maintain the stability of Gwangju, so the matter of Gwangju was dragged down like this. ”

"However, Ben Jiang felt that with the temperament of these remnant generals of Caizhou, I was afraid that there would be chaos in the future; Therefore, in order to prepare in advance, more than two years ago, Ben General sent someone to dig a tunnel from outside the city to the city. ”

"Unfortunately, in order not to be detected by the rebels, Ben will be very secretive when digging the tunnel, but this will also delay the speed of the excavation. After two years, this tunnel has now been dug under the city wall. At our original pace, it may take more than a year to dig it through. But now that the troops have come to the city, the speed of digging tunnels can naturally be faster. If you look at it at a normal rate, it may take a month to dig it through. Chai Zaiyong said with some regret.

"A tunnel that will soon be dug under the walls?" Qin Pei and Li Yu were surprised and delighted, they didn't expect Chai Zaiyong to do nothing in Gwangju on the surface, and secretly he was about to dig a tunnel, which really surprised them.

The method of digging tunnels into the city is not new, but this method is not only time-consuming and labor-intensive, but in wartime, the defending side often has someone responsible for listening to the underground to prevent the enemy from digging the tunnel. Therefore, when there is no way, the besieging side will not use the means of digging tunnels.

However, in peacetime, the monitoring of the underground is much more relaxed, but correspondingly, because the right to use Chai Zaiyong has long been hollowed out, there are many Caizhou people around him to monitor him, so in order not to be discovered by them, Chai Zaiyong only sent a small number of people to dig, and the efficiency is naturally much lower, and it took more than two years to dig under the city wall.

However, for others, digging tunnels is not completed until they are dug into the city, but for today's Huainan army, they only need to dig under the city walls.

"General Chai, are you sure that this tunnel has been dug under the city wall?" Qin Pei sat up straight and asked solemnly, and Li Yu on the side also looked serious, obviously very concerned about this issue.

Chai Zai recalled carefully for a moment, and then nodded: "Yes, Ben will be able to confirm." At the beginning, the general also went to measure it himself, and according to the length, the tunnel was at the foot of the southern city wall. It's just that General Qin and Li Yuanjun, I don't know why the two of you are so interested in this issue? ”

Li Yu and the two glanced at each other, and couldn't help but smile on their faces.

"General Chai has been staying in Gwangju for the past few years, so he must not know much about the current Huainan army, right? It's just that the general may not have heard of anything else, but black powder must have heard of it, right? Qin Pei said with a smile.

Black powder has always been Huainan's secret weapon, and its most important thing is the best ratio of its three ingredients, as long as this ratio is not leaked, even if the enemy can get the actual black powder, it is not of much use.

Therefore, compared with the Suzhou cannon that has long been circulated and imitated by some forces, black powder is not only easier to keep secret, but also more secretive, although all parties know that there is something in Huainan that will make a loud noise that shakes the earth after it is ignited, and then the city wall will suddenly collapse; However, for this secret weapon, everyone only knows that it is called black powder, but they don't know what it is.

Although there are also black powder used in the military by various forces in this era, there are natural deficiencies in the formula, not only the amount of carbon and sulfur is too much, but also a lot of ignition is added, after ignition, it can only cause deflagration, but can not cause explosion, which is inconsistent with the characteristics of Huainan's black powder; In addition, the name black powder is still appearing for the first time, so although some people associate it, they can't confirm it in the end.

And although Chai Zaiyong is also a general of Huainan, he has stayed in Guangzhou for a long time, and he knows no more about black powder than the generals of other forces, and at this time, after listening to Qin Pei's words, he couldn't help but ask in a surprised voice: "But what General Wang Maozhang used when he broke through Runzhou?" ”

"Yes, it is the secret weapon that General Wang Maozhang used to break through Runzhou!"

At the beginning, in order to quell the rebellion of Tian Yan, Yang Wu had stored a large amount of black powder in advance, enough to go to the Xuanzhou city wall after the collapse of Runzhou City, but later Tian Yan went out of the city and died in a battle and was not used.

This time, Yang Wu specially ordered Qin Pei to bring enough black powder, a full 3,000 catties, to blast the city wall at the right time.

To blast, you need to dig a hole under the city wall, which is also the most troublesome point, but I didn't expect that firewood reuse has been completed for them.

Qin Pei and the others were overjoyed on their faces, and told Chai Zaiyong their thoughts, and Chai Zaiyong knew what was going on.

On the same day, the three of them entered the tunnel again to measure, and confirmed that the tunnel was indeed excavated at the foot of the city wall, so they returned to continue discussing the battle plan, and finally decided to launch a siege battle that night.

Late at night.

Although the rebels in Gwangju were all remnants of the original Caizhou army and were the real tiger and wolf division, after so many years of comfortable life, the former elite of a hundred battles had also degraded a lot, not only was Qin Pei a little panicked when he led the army to the city quickly, but also many preparations for defending the city were not done well throughout the day.

As the leader, although Wang Yan was a little uneasy in his heart, he didn't think much about it, after all, although the Huainan army was in a hurry, it was impossible to launch a siege battle so quickly, so he just urged everyone to complete the preparations for defending the city as soon as possible.

Just as Wang Yan and several other rebel generals were discussing countermeasures, a report suddenly came from outside that the Huainan army was assembling under the city, and it seemed that they were preparing to attack the city.

Wang Yan felt a little incredible, the Huainan army came from afar, not to mention that the soldiers were tired, but the siege equipment was not built, how to attack the city? Could it be that they built the siege equipment in advance and brought it with the army?

He hurried to the city tower, only to see the Huainan army outside the city holding torches lined up 800 steps outside the city, but there was no further action, as if waiting for something.

"Firewood has been used in Gwangju for many years, so it won't be any internal response, right? Ready to open the gates tonight? Wang Yan guessed, and hurriedly sent people to inspect the other gates, and personally led people to inspect the vicinity.

However, what awaited them was not an internal response, but an earth-shattering loud noise, in the roar, the city wall of Gwangju collapsed, and the Huainan army took the opportunity to launch a tidal attack, and after half a day of fierce fighting, finally took the outer city on the morning of the next day, completely surrounding the rebels in the inner city.

That night, after an afternoon of rest, the Huainan army attacked again, and finally broke through the inner city and completely wiped out the Gwangju rebels.

Since then, the Gwangju rebellion has been put down in just six days, and when the news broke, Huainan was shaken.
