But the originally good Lei family, but because of a trivial matter, offended a prince who was particularly loved by the king of the Southern Han Dynasty, so it caused a catastrophe. And because this Lei Bin was in charge of a construction project in other places at the time, he was able to escape the arrest of the government with the help of his friends after getting the news. Later, he has been living incognito until now.

After hearing that Gongsun Jian led his troops to attack the Southern Han Dynasty, he realized that his chance to avenge his family had come. Therefore, he rushed from the hiding countryside to the outside of the capital overnight to ask for Gongsun Jian, hoping to contribute to the defeat and destruction of the Southern Han Dynasty by the Zhou army.

After listening to Lei Bin's story, Gongsun Jian couldn't help frowning slightly, he wasn't afraid that the other party was a spy deliberately sent by the Southern Han Dynasty, but he just doubted that a person who was engaged in construction could help him. At most, it is to provide some data on the height and thickness of the walls of the Southern Han capital. But after all, it is still up to his soldiers to fight. And the problem at the moment is that most of Liu Mang's army is stationed on the periphery of the capital, and if he wants to attack the city, he must first destroy the nearly 200,000 Southern Han army.

But Lei Bin's next words made Gongsun Jian and Shi Fangheng, Qian Tuan, and other civil and military ministers who accompanied the inquiry, overjoyed. Because the Lei family knows a secret that even the kings of the Southern Han Dynasty did not know. That is, there is a secret passage in the palace of the Southern Han capital that can lead directly to the outside of the city, which is a back road specially built by the first Southern Han king because of the instability of the regime. Later, because the situation in the DPRK was stable, he gave up continuing to build, but even so, most of this secret passage was built. In the following decades, the descendants of the Lei family secretly built all this passage.

Gongsun Jian asked with some curiosity why the Lei family continued to cultivate this abandoned secret passage. This is a head-killing disaster! And Lei Bin's answer was that when the ancestors of the Lei family followed the first generation of Southern Han kings at the beginning, they knew that the Liu family was not normal, not only with a violent and cruel temperament, but also suspicious by nature. If you work under such a person, you may be unlucky one day. Therefore, the Lei family wants to leave a way back for future generations, once there is danger, the descendants of the Lei family can take revenge at the cost of this, in exchange for rewards from other countries, at least it is also a means of countermeasures.

"Mr. Lei, what you just said is the truth?" Gongsun Jian asked the other party in disbelief.

"Your Royal Highness King Zhou, the villain can swear in the name of my life and the ancestor of my Lei family. What Fang just said was not half a lie. ”

"Then let me ask you, that secret path is really unknown to no one except for your Lei family's descendants. Even the King of the Southern Han Dynasty doesn't know? ”

"That's true. After the first generation of the Southern Han Dynasty gave up the construction, in fact, my ancestors realized that the secret passage might bring disaster to my Lei family. So after secretly telling his sons, he deliberately died in an accident on the construction site. And the old king of the Southern Han Dynasty saw that my ancestor was dead, and later executed a group of people who participated in the construction, but he did not harm my Lei family again. Not long after, the old king of the Southern Han Dynasty also died. Therefore, no one knows about this matter except my Lei family. ”

"How long is that secret passage? How many people can be allowed to pass through in a tie, and where are the exits in the palace? Gongsun Jian asked several questions in a row.

But Lei Bin replied unhurriedly: "The part that was built before can allow five people to pass side by side, but later my Lei family secretly excavated and built only for one person to bend over and pass." The whole secret passage is about four miles long, of which the part that was built before is about less than three miles, and the back of my Lei family repaired it, then changed the direction, in order to conceal and facilitate the transportation of soil, we set up the secret passage out of the city in a very secret position under the embankment of the fork river outside the city. The entrance to the palace is in a side hall in the northeast corner of the palace. ”

"Has the secret passage on the side of the palace ever been blocked?"

"It was really blocked after the shutdown. But later, my Lei family took advantage of their position to work together inside and outside to get through again. And the entrance has been renovated to be very secret, and people who don't know won't notice it or open it. ”

"In this case, this king can send troops to directly attack the palace of the Southern Han Kingdom through the secret passage?" Gongsun Jian asked with his eyes fixed on Lei Bin.

"That's true. That's why I came to see His Royal Highness King Zhou. ”

After listening to Lei Bin's answer, Gongsun Jian closed his eyes and thought carefully, and only after a long time did he open his eyes and look at the people in the tent, including Lei Bin: "What do you think of this matter?" ”

"Lord Wang." Shi Fangheng was the first to reply: "My subordinates feel that this matter is too strange, and they need to be seriously investigated before they can make a decision. It's not that I don't believe Mr. Lei's words, but the current situation can't tolerate the slightest mistake or omission. ”

Gongsun Jian nodded slightly when he heard this, and then looked at the others.

"Your Highness, the old man thinks it's better to send someone to investigate first, and then make a decision." Qian Tuan, the king of Chu on the side, also opened his mouth and agreed.

"His Royal Highness King Zhou, if you don't believe what Lei said, you can send someone to follow me. In addition, the Southern Han Dynasty Palace was originally built by the ancestors of my Lei family, and then the descendants of my Lei family were responsible for repairing and renovating. Therefore, all the buildings and terrain are in Lei's mind, and they can be drawn at any time for the reference of the army. ”

"Oh!" Gongsun Jian suddenly came to the spirit. It's a treasure, and with a detailed map, it's much easier to fight.

"Mr. Lei, then ask you about the topographic map of the capital of the Southern Han Dynasty, and you may draw it?"

"It's a no-brainer. It's just that Lei only knows the location of all the streets and alleys and the city gates, but he doesn't know the situation of the garrison. After all, no one in my Lei family serves in the army. ”

"It doesn't matter, as long as the capital and the palace are accurately mapped." Gongsun Jian stood up with a smile and walked in front of Lei Bin.

"Then please sir draw the topographical map first, and then I will send someone to check the tunnel with you. I wonder what Mr. thinks? ”

"No problem, as long as His Royal Highness can avenge my Lei family, even if it is for me to let Lei Bin die." Lei Bin said with some excitement.

That night, Lei Bin used the pen, ink and paper provided by Gongsun Jian to draw a topographical map of the capital city and the imperial palace of the Southern Han Dynasty. There are more than ten huge sizes, and every corner of the Southern Han capital is clearly marked in detail. Gongsun Jian had to take a look at Lei Bingao. This is a talent!

During the day of the next day, the Zhou army hung up the exemption card and went all out to defend the camp. And Gongsun Jian and the main generals of the Zhou army held a military meeting nervously.

"Ladies and gentlemen, the Southern Han army opposite us is our main enemy at the moment, but once the capital of the Southern Han Dynasty is lost, how much fighting spirit do you think these soldiers outside the city will have? Therefore, I decided to send someone to scout the secret passage first, and then draw up a detailed battle plan based on the actual situation. What do you think? Gongsun Jian looked at the generals in the tent and asked. And almost all of them nodded in agreement.

It would be much easier to break through from the inside, otherwise even if the Southern Han army outside the city was solved, the cost of the loss would not be small. It is not even known who will win or lose in the end.

Xie Wu was the first to stand up and said to Gongsun Jian: "My lord, I will personally lead someone to follow the surnamed Lei tonight." Let's see if the secret passage is a trap and if it is possible for us to use it. ”

"Okay." Gongsun Jian nodded in agreement.

"In addition, Lao Xie, you remember, after entering, check clearly, how many soldiers and horses can be hidden in the entire passage, and what is the situation at the exit, so how long it will take for the soldiers and horses to rush out together, these must be clarified. Do you understand? ”

"Well, don't worry, sir. The subordinates must do a good job. ”

As he spoke, Gongsun Jian turned his head to look at an unfamiliar face and said, "Chen Jia, you have to find a way to sneak into the city to contact your family." Ask if you can get a few sets of clothes for the eunuchs in the Southern Han Palace. There is also the question of whether we have our own people working in the palace. ”

Chen Jia smiled and said, "Lord Wang, you don't need to ask Lord Zhao about this. I'll be able to answer you. I'll be able to get the clothes by tonight. In addition, we bought several eunuchs in the palace and a school captain who guarded the palace. In addition, not far from the side door on the east side of the palace is a stronghold of our intelligence department. There are a lot of blades and other things in it. ”

"Hahaha, good job." Gongsun Jian laughed when he heard this.

"Chen Jia, you have done well in the past two years, and you have suffered a lot in the enemy camp, right?"

"What a hardship! Lord Wang, you see, aren't you all working for the people and our Great Zhou. Chen Jia smiled and said modestly.

"That's right, Lord Wang. I just heard you talk about things. I almost forgot what our Lord Zhao commanded. My lord, I have asked you to entrust you with the deployment of the garrison in the capital. As he spoke, he raised his foot and took out a wax pill from under his boot and handed it to Gongsun Jian.

Gongsun Jian broke open the wax pill, and inside was a note with dense writing on the deployment of troops in the capital of the Southern Han Dynasty.

"Good! This Zhao Changle did a good job. Gongsun Jian slapped the table and smiled happily to everyone: "Didn't Mr. Lei spend a topographic map for us, and now there is the deployment of troops in the city." As long as that secret passage is available, then the capital of the Southern Han Dynasty can be said to be at your fingertips. Hahaha......"

All the generals and officials were overjoyed when they heard this. Immediately, they began to discuss how to fight next. Wei Meng, who was on the side, said angrily: "I said that Zhao Changle's kid hasn't been seen for more than half a year, it turns out that this kid went to the capital of the Southern Han Dynasty." ”

In fact, it wasn't just him Wei Meng who didn't know, except for Chen Jia, who was subordinate to the Intelligence Department, only Gongsun Jian and Shi Fangheng knew about it. And the other ministers of civil and military affairs don't know about it. This is also the task and plan that Gongsun Jian arranged early on. And now it's finally paying off.

However, despite this information, it is up to us to see if the secret passage leading to the palace can be of use.

"Lao Xie, you go back and choose a few white-looking warriors to go with you to scout at night. In addition, I asked Zhao Changle to send someone to cooperate with you in the palace. Turn around and change into eunuch clothes, go out of the palace and check it in detail. The information was brought out again through Chen Jia. No one else has to come back but you. When the time comes, the men who cooperate with the intelligence department in the city will create chaos when we attack. ”

"Hmm. The subordinates got it. It seems that there are more people to bring with them. ”

"Master Xie, you don't need too many people." Chen Jia opened his mouth and reminded: "There are too many people to come out of the palace, and it is easy to be exposed, and we also have some strength in the city, which is enough to create chaos when the time comes." The only requirement is that you can bring some explosives or grenades or something. When the army is attacking the city, it will be convenient for us to blow up the city gates. ”

"Okay, that's fine."

The next day, the Zhou army went out of the camp and fought with the Southern Han army. There were not many people, and after a short fight, Mingjin collected his troops and returned to the camp. Because there is a degree of advance and retreat, it is not that you can't parry the opponent's attack. Therefore, the other side was not given a chance to pursue at all. In this way, the time of the day passed again.
