He Nan was like a basin of cold water poured from head to toe, and his whole body was covered with cold bones, like a sculpture, and he didn't move for a long time. The blow was too big and the turning point came too suddenly.

Li Yanqing looked at him coldly, and seeing that he finally came to his senses, he waved his hand, "Please sit down!"

He Nan's mind was blank, and he moved his steps mechanically, sitting down like an aging robot. At this time, a huge fear enveloped his whole body, and he had exposed himself, and he could land on the ground at any time, but the other party was Li Yanqing! How could he interrogate himself in person? He was still so polite. Gradually, the fear faded in his heart, and became panic and confused.

At this time, a personal soldier came in and served them two cups of tea. Li Yanqing picked up the tea and tasted it and said with a smile: "It really affects the business of the teahouse! No matter how good the tea is, no matter how good the tea art is, it cannot save the fatal injury of the water quality."

"Don't Li Du Tong killed me?" He Nan asked in a low voice. He still didn't care about tasting tea at this moment.

Li Yanqing shook his head, "It's up to you whether to kill or not. If we cooperate well, you can continue to be promoted and make money in the future. If the cooperation is not good, you will indeed be the one who will be the one who chooses. The choice is up to you."

"What the governor means is to let me betray the Jin Kingdom?"

"It's not a question of betrayal. You are still a minister of the Jin Kingdom. You can still pass some information to the Jin Kingdom. It's up to me to decide what information you pass. Of course, most of the information you pass is real."

Li Yanqing looked at He Nan, and saw a trace of cunning flashing in his eyes, he lowered his face and said, "Don't be lucky, and don't think I'm easy to fool you. I won't kill you, just because you have value for use. If you destroy the value for use yourself, then you will definitely die. You are a smart person and you should understand what I mean."

A trace of luck that just emerged in He Nan's heart was ruthlessly extinguished by Li Yanqing. He lowered his head, sighed for a while, and asked, "What do you want me to do?"

"I just want you to send me some information to the Jin Kingdom at a critical moment. That's all, can't you do it?"

He Nan nodded silently, "I can do it, but I must collect intelligence for the Jin Kingdom, or even collect important intelligence, otherwise the Jin Kingdom will replace people."

"I know this, I said, I will give you some information, or provide you with some ways to collect information."

Speaking of this, Li Yanqing threw a roll of paper to him, "There are two information here, one is the grain inventory in the capital, and the other is that I will give you a brand new iron fire thunder."

He Nan was shocked and his eyes widened, "Do you give me an iron fire thunder?"

"This is actually not a secret. We cleaned the battlefield and took back more than 70 iron fire thunders without explosion. If the Jin soldiers were determined, they should have picked it up long ago. Besides, even if they gave you iron fire thunders, you would not be able to create it."

He Nan sighed, "President Li is right. We seized more than 20 Song Dynasty thunders in Yanshan Prefecture, and Xixia also gave us some gunpowder formulas, but after imitation, it was wrong. At least seven of the ten thunders could not explode. I don't know which link was wrong, so the highest task given to me by the Jin Kingdom was to get the gunpowder formula and production secret of the thunders."

"Then don't worry. The recipe for the thunder gunpowder is the highest secret of the Song Dynasty. Even He Fang doesn't know. The only way for you is to keep experimenting. Maybe one day it can be made. Xixia took a year to find a trick, but the thunder they created is still flawed. As for the iron fire thunder, even the craftsmen in the capital cannot make it. Otherwise, I would give you an iron fire thunder so generously?"

He Nan showed a bitter smile on his face, and he had no choice but to nod and said, "I understand, if the governor had nothing else, the villain would say goodbye."

Li Yanqing glanced at him and said coldly: "I said ugly things ahead. We cooperated well. You have nothing to do. If you dare to disobey the emperor, even if I can't kill you, I will use the Jin Dynasty's hand to kill you. You can do it yourself!"

He Nan was shocked all over, and he nodded, "Please rest assured, I understand in my heart!"

Li Yanqing pointed to Zhang Hu next to him and said, "This is my confidant and also joining the army of the Intelligence Department. He will contact you on a single line in the future."

He Nan glanced at Zhang Hu deeply, bowed to Li Yanqing, and turned around and left in a hurry.

When He Nan left, Li Yanqing took a sip of tea and asked Zhang Hu with a smile, "Do you think this person is trustworthy?"

Zhang Hu pondered for a moment and said, "This person is not a Jurchen, but a surrendered minister of the Liao Kingdom. He is not loyal to the Jin Kingdom. He also thinks he is a smart person and he will control the right position. As long as he is not forced to force him too hard, I believe he will cooperate with us."

Li Yanqing smiled again and said, "Have you heard of two-faced spies?"

Zhang Hu shook his head, "I don't know about the humble position!"

"It is to be a spy for the Jin Kingdom and also work for the Song Dynasty. Just like this He Nan, he is a detailed worker of the Jin Kingdom, but he also works for me secretly. This is called a double-faced spy."

"But such a person is also very dangerous." Zhang Hu did not match Li Yanqing's words.

"A knife can hurt yourself or kill enemies, it depends on how you use him."

Li Yanqing knew that Zhang Hu couldn't understand something, so he waved his hand and said, "In two days, you can give him an iron fire thunder, and then don't contact him again, and don't monitor him, just watch with a cold eye."

"Abide by the orders!"

Of course, he had to leave room for himself when reporting the situation to his leader. He Fang promised Li Yanqing that the super trencher would be built at night. In fact, it was not yet dark, and three super trenchers appeared in the northwest corner of the city wall.

The soldiers rushed from all directions and surrounded this huge guy and whispered. Not only ordinary soldiers, but also veterans who had been in trouble for more than ten years, were the first time they saw such a huge catapult.

"This kind of catapult is rare!" a soldier asked loudly.

“Rare?”

The old craftsman who was untiing the rope sneered, "This is the largest trencher since the founding of the Song Dynasty, and it is not only rare!"

The soldiers around were exclaiming, and at this time, someone shouted, "The governor is here!"

The soldiers dodged a path, and saw Li Yanqing hurried over with more than a dozen generals. He Fang hurried forward to salute, "The craftsmen have installed overnight and finally completed!"

"Okay! It's a credit to be able to complete it in advance."

The pyramid built by the Jin Kingdom opposite is almost capped, and it can be completed tonight. It can be two or three hours earlier than the other party, which is the chance to win. Li Yanqing immediately said to He Fang: "A reward of 5,000 jin of money, all the craftsmen who participated must have a share!"

The craftsmen were overjoyed and hurried over to salute and thank him. Li Yanqing waved his hand and said, "You have to work hard for a while. You can't take care of these three catapults without anyone to take care of them. Please stay! Keep the catapults a little more carefully and don't be blown by your own thunder."

Li Yanqing has been in contact with the catapult for so long, and he is half an expert. After all, the catapult is made of wood. Although it is powerful, it is easy to damage. Especially this super giant catapult looks very majestic, but it is actually not reliable. It is okay to throw a thunder once or twice with it. If there are too many, there will be danger. Li Yanqing must let these craftsmen stay and observe the situation of the catapult at any time.

The supervisor next to him smiled and said, "Don't worry, even if you didn't say it, we will stay. This thing is the first time everyone has made, it's not a secret!"

"That's good!"

Li Yanqing immediately let the soldiers disperse, and he quickly walked up to the city wall. At this time, the twilight had quietly arrived and the sun had already set, but the sky was still a light blue color. The "pyramid" in the distance was shrouded in a layer of black fog, but the outline could still be clearly visible.

At this time, a slender object appeared on the pyramid. Li Yanqing squinted his eyes and looked at it for a moment. It seemed to be a piece of wood, but the pyramid has not been completed yet. What should I do when pulling the wood?

A thought suddenly flashed through Li Yanqing's mind, and Li Yanqing slapped his forehead suddenly, "Not good!"

I actually made a mistake. The other party wanted to build a platform. Of course, I would not build any spires again. It must be a flat roof. I always thought about the pyramid, but I misled myself. Needless to say, the other party is now hanging large wood and must be building a stone-treating machine.

At this time, Liu Qi quickly walked forward and said, "I was about to report to the governor that the other party had already built a high platform and should be building a stone-treating machine now."

Li Yanqing nodded. He didn't want his opponent to tell him what he was doing, so he ordered his personal soldiers to "go and find Wang Zhengshen."

Wang Zhenggong's name is Wang Hui. He is the chief craftsman of the Crossbow Floor. He is an old man in his fifties. He is responsible for supervising the construction of the super trencher. After a moment, Wang Zhenggong rushed over, "What are the commands for the governor?"
