As usual, a team came to a place eight or nine hundred meters outside the city, set up a field bed crossbow, and shot dozens of arrows.

It's just that the dozen or so arrows are not meant to shoot people but to distribute leaflets, so most of them flew over the city and landed in the city, and the content of the leaflets is still to persuade them to surrender, this is the homework that Li Yunfei asked the troops to do every day, whether they succeed or not, they can hit the morale of the defenders, and at the same time, they will also let the people in the city avoid the city wall as much as possible, because the arrows will fall at any time, and the possibility of hurting the innocent will be a little less when the city is really attacked. For the bombardment of this information, the Cao army at the head of the city had no choice, all they could do was to scold a few times and let out their anger.

The army was preparing to attack, and Li Yunfei also sent a few very large rocket burst arrows, but this thing has been named a rocket by Li Yunfei, and the bomb has undergone some modifications, adding flying wings and vertical tails, so that the rocket flight is more stable, and this rocket can pierce the thick city gate with one shot.

The rocket is really big, the whole rocket is about one meter eight long, weighs 60 kilograms, the warhead is loaded with six kilograms of refined black powder, the power of the explosion is equivalent to one kilogram of TNT, if you have to say that the power is about the same as 76mm shells, the power of the explosion can not only blow up the city gate, even the city wall can be blown up, just like Xiao Qiao said, as long as the city wall is blown down, the arrow rain washes the ground, and then the army rushes up, Cao Jun can't stop it at all......

"Lord, there is a young man who calls himself Sima Yi, saying that he has a good strategy for attacking the city, and he can help the lord's soldiers take Beiping City without blood." Thirty-nine entered the camp and reported one thing directly.

"Sima Yi?" Hearing Sima Yi's name, he was a little puzzled, and that guy also took the initiative to vote for it, and it was a very serious question whether to accept it.

"Yes, then Sima Yi, is there anything wrong?"

"It's nothing, you bring people in!" Li Yunfei was confident that he could easily suppress him, so he didn't have any fear. It's good that this guy is ambitious, but who is a smart person who wants to go out of the mountain doesn't have some ambition, even Zhuge Liang seems to have a lot of ambition.

"Grass people Sima Yi, I've seen Lu Gong!" As soon as Sima Yi came in, he hadn't seen anyone clearly, but his head had touched the ground.

"You're welcome, get up and sit down!" Li Yunfei waved his hand and said.

"Thank you Lu Gong!"

"I heard that you have a good plan to break the enemy?"

"Back to Lu Gong, the grass people do have a good plan, which can allow Lu Gong to easily take Beiping City."

"Well, so what do you want?" Li Yunfei asked suddenly.

Li Yunfei's question made Sima Yi stunned for a moment, according to common sense, what good strategies should be asked, and then after listening to it, he greatly appreciated his courage, and then recruited him as a staff member...... Why didn't things go on this way?

"Caomin wants to ask Lu Gong to write a handwritten letter and let go of his father Sima Fang!" Sima Yi quickly came back to his senses, if he didn't want anything, he would be suspicious, so he simply made a request, saying that filial piety comes first, and if he does this, this Lu Gong should have a better opinion of himself.

Of course, this is also one of the main reasons why he came to offer advice, his old father has always followed the Son of Heaven, but now he is surrounded by a large army in Shouchun City, and he may have a bad appetite at any time.

"Well, Sima Fang is a person worthy of respect, loyal and upright, I naturally won't embarrass him. If you can really take Beiping City without blood this time, I will count you as a second-class merit, with a second-class meritorious service, the road to promotion as an official in the future will be much easier! Li Yunfei suddenly felt that it would be a great thing if this guy's ingenuity was used to do things for the people.

If you want to talk about his ambition, in fact, this guy is very similar to Cao Cao, if it is a peaceful and prosperous world, he will naturally be a diligent and good official, but when he encounters troubled times, of course people will become extremely treacherous, otherwise he will really not be able to get along.

"Thank you for your appreciation, and the grass people are grateful."

"Well, you're welcome, now let's talk about your good plan!"

"Lord, please look!" Sima Yi took out a scroll, and when he spread it out, it was a drawing of Beiping City, and he could still see a large pond in Beiping City, with a hidden aqueduct connecting the Chaobai River three miles away......

Sima Yi's strategy is very simple, in fact, he went in to plot against Yuan Jun in the city, he and the two Yuan Xi's generals in the city knew each other, and he was confident that he was 100% sure to persuade them, and by the way, he gave them advice, how to defeat Cao Jun, and then he could easily take the city under the cooperation of the outside world. Li Yunfei thought about it and agreed, anyway, it wouldn't be a loss to let him try it. After saying the code and approximate time, Sima Yi also went directly to a rather secret water diversion entrance a few miles away.

To be exact, it was a water inlet, but the water level has changed in recent decades, but this water inlet has been abandoned, in fact, there is a certain danger, such as some snakes, insects, rats and ants or something, but this Sima Yi was also prepared, and he was coated with a legendary snake avoidance, and he directly entered the secret secret passage.

……

"The general doesn't even ask him where this atlas came from?" Xiao Qiao reminded that these atlases are obviously of great military value.

"Nine times out of ten, I got it from his father, his father used to be a big official, and when he escaped from Chang'an with the Son of Heaven, he probably brought a lot of information with him?"

"The general should ask how many of these atlases there are, where they are placed, etc., if we get these atlases, it will still be of a lot of help to attack the city."

“…… It doesn't matter, in fact, sneaking in with the help of a secret passage, there are some miraculous effects for the first time, and doing it one after another is equivalent to giving people their heads. Everyone is not stupid, I heard that people are always infiltrated through secret passages, and they have to quickly find the secret passages in the city to block them or send troops to handle them...... In fact, Sima Yi dared to do this, it was to bully Cao Jun to take over this city for less than half a year, if not, the possible secret passage would have been blocked in wartime. Li Yunfei actually felt that he had miscalculated a little, if this Sima Yi accidentally hung up when he went in, it was likely that the atlas with a lot of reference value would not be found, but he didn't want to admit it in front of the little girl, so he argued.

“…… Anyway, whatever the general said made sense, and he didn't say anything about it in the future. Xiao Qiao turned around and left, looking a little lost, of course, not because Li Yunfei didn't admit the miscalculation, but because Li Yunfei was like Xiaobu, he still didn't accept her last night, so he couldn't help but be a little disappointed.

Another point is that when Hu Yi came to report the situation in the morning, she was outside the military tent, Li Yunfei told Hu Yi to go to the Southern Xiongnu to rescue a talented woman named Cai Yan, which really made her a little uncomfortable, if it was just a simple rescue, of course it was nothing, but the mysterious appearance of the two of them, there must be a problem......

"Aren't you, are you angry?" Seeing that Xiao Qiao left a little depressed, Li Yunfei stepped out and fished people back, and Xiao Qiao also leaned into Li Yunfei's arms.

"How dare you be a concubine!"

“…… Well, I guess you're mistaken, I smell sour. ”

"No, not really...... The general can be a woman for as many years as he wants, but the general cannot abandon the concubine. ”

"How is it possible, it's too late to hurt you, how can I abandon you!" Li Yunfei really couldn't figure it out, why Xiao Qiao was always worried that she would abandon her, and so was the trainer at that step, why didn't such a beautiful and lovely beauty have any confidence?

“…… The concubine has always wanted to change this jealous character, but it has always had little success, and she asks the general for forgiveness. ”

"Look at what you said, who are you jealous of this time, it seems that you are a great beauty next to me!" Li Yunfei said that his hand was also groping on Xiao Qiao for a while, and she could drip out of her blushing face, if she teased Li Yunfei in a few minutes at night, but it was daylight now, so it was really embarrassing.

"No, no, really not, the concubine is going to count the supplies, and the concubine is retiring." Xiao Qiao broke free for a long time before he could be regarded as breaking free of Li Yunfei's clutches, and even his walking posture became a little different......
