He Nan was like being poured a basin of cold water from head to toe, and the whole person was cold to the bone marrow, just like a sculpture, he didn't move for a long time, this blow was too big, and the turning point was too sudden.

Li Yanqing looked at him coldly, and saw that he finally came back to his senses a little, so he waved his hand, "Please sit down!" ”

He Nan's mind was blank, and he moved mechanically, like an aging robot, and sat down blankly, at this time, a huge fear enveloped his whole body, he had been exposed, and he could hit the head on the ground at any time, but ..... The other party is Li Yanqing! He.... How could he interrogate himself in person, and still be so polite, gradually, the fear faded in his heart, and he became panicked and dazed.

At this time, a personal soldier came in and served them two cups of tea, Li Yanqing picked up the tea and said with a smile: "The water is not good, it really affects the business of the teahouse!" No matter how good the tea is, no matter how good the tea art is, it can't recover the fatal wound of water quality. ”

"Won't Li Dutong kill me?" He Nan asked in a low voice, he still didn't care about tasting tea at this time.

Li Yanqing shook his head, "It's up to you whether you kill or not, if we cooperate well, then you can continue to be promoted and make a fortune in the future, if the cooperation is not good, you will indeed fall to the ground, and how to choose is up to you." ”

"What does Dutong mean by letting me betray the Jin Kingdom?"

"It's not about betrayal, you are still a courtier of the Jin Kingdom, you can still pass on some information to the Jin Kingdom, but it is up to me to decide what information to transmit, of course, most of the information you pass is true."

Li Yanqing looked at He Nan, and saw a trace of cunning flashing in his eyes, so he lowered his face and said: "Don't be lucky, let alone think that I'm so foolish, I won't kill you, just because you have use value, if you destroy the use value yourself, then you will definitely die, you are a smart person, you should understand what I mean." ”

The trace of luck that had just emerged in He Nan's heart was ruthlessly snuffed out by Li Yanqing, he lowered his head, sighed for a while, and asked, "What does Li Dutong want me to do?" ”

"I just want you to pass on a few pieces of information to Jin Guo for me at a critical moment, that's all, can't you do it?"

He Nan nodded silently, "I can do it, it's just ..... I have to gather intelligence for the Jin country, and even collect important information, otherwise the Jin country will be replaced. ”

"I know that, I said, I'll give you some information, or give you some ways to gather information."

Speaking of this, Li Yanqing threw him a roll of paper, "There are two pieces of information here, one is the grain inventory in the capital, and the other is that I will send you a brand new Iron Fire Thunder." ”

He Nan was taken aback, his eyes widened, "You gave me an Iron Fire Thunder?" ”

"This is actually not a secret, we cleaned the battlefield, and more than seventy iron fire thunders were recovered without exploding, if the golden soldiers had a heart, they should have picked it up a long time ago, besides, even if they gave you iron fire thunder, you couldn't make it."

He Nan sighed, "Li Dutong is right, we seized more than 20 earth-shaking thunders of the Song Dynasty in Yanshan Mansion, and Western Xia also gave us some gunpowder formulas, but after copying them, it was not right, at least seven of the ten earth-shaking thunders could not explode, I don't know which link went wrong, so the highest task given to me by Jin Guo was to get the gunpowder formula and production secrets of the earth-shaking thunder." ”

"Then don't bother, the formula of the earth-shaking thunder gunpowder is the top secret of the Great Song Dynasty, even He Fang doesn't know, your only way is to keep experimenting, maybe one day it can be matched, Xixia also took a year to find a little trick, but the sky-shaking thunder they made is still flawed, as for the iron fire thunder, even the craftsmen in the capital can't make it, otherwise, I will give you an iron fire thunder so generously?"

He Nan showed a wry smile on his face, helpless, he had to nod and say, "I understand, if there is nothing else to do, the villain will leave." ”

Li Yanqing glanced at him and said coldly: "I said ugly things in front, we cooperate well, you have nothing to do, if you dare to disobey yin and yang, even if I can't kill you, I will kill you with the hand of Jin Guo, you can do it yourself!" ”

He Nan was shocked, 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 henchman, and he is also a member of the Intelligence Department, and he will contact you in the future." ”

He Nan took a deep look at Zhang Hu, bowed to Li Yanqing again, turned around and left in a hurry.

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

Zhang Hu pondered and said: "This person is not a Jurchen, but a subordinate of the Liao State, and his loyalty to the Jin State is not high, and he thinks that he is a smart person, he will control the proportions, as long as he is not forced too hard, I believe he will cooperate with us." ”

Li Yanqing smiled again: "Have you ever heard of a double-faced spy?" ”

Zhang Hu shook his head, "I don't know if I am humble!" ”

"It is not only to be a spy for the Jin Kingdom, but also to do things for the Song Dynasty, just like this He Nan, he is the meticulous work of the Jin Kingdom, but he also secretly does things for me, this is called a double-faced spy."

"But such people are also dangerous." Zhang Hu did not agree with Li Yanqing's words.

"The knife can hurt oneself or kill the enemy, depending on how you use it."

Li Yanqing knew that Zhang Hu still couldn't understand something, so he waved his hand and said, "In two days, you give him an iron fire thunder, and then don't contact him again, and you don't need to monitor, just watch from the sidelines." ”

"Obey the order!"

.........

Of course, to report the situation to the leader, you have to leave room for yourself, He Fang promised Li Yanqing to build a super trebuchet at night, in fact, before it was dark, three super trebuchets appeared in the northwest corner of the city wall.

The soldiers came from all directions, surrounded this huge guy and whispered, not only ordinary soldiers, but even veterans who had been mixed for more than ten years were the first time to see such a huge trebuchet.

"This kind of trebuchet is rare!" A soldier asked in a loud voice.

"Rare?"

The old craftsman who was untying the rope sneered, "This is the largest trebuchet since the founding of the Great Song Dynasty, it's not just rare!" ”

The surrounding soldiers exclaimed, and at this time, someone shouted, "All are here!" ”

The soldiers dodged a way one after another, only to see Li Yanqing hurrying over with more than a dozen generals, He Fang hurriedly stepped forward and saluted, "The craftsmen installed it overnight, and it was finally completed!" ”

"Good! It's a credit to be able to finish it ahead of schedule. ”

The pyramid made by Jin Guo on the opposite side has almost been capped, and it can be completed tonight, two or three hours earlier than the other party, that is the chance to win, Li Yanqing immediately said to He Fang: "Reward 5,000 yuan, all the participating craftsmen must have a share!" ”

The craftsmen were overjoyed, and hurriedly came over to salute and thank them, Li Yanqing waved his hand and said: "I have to trouble everyone to work hard for a while, these three trebuchets can't be taken care of by no one, everyone stays!" Keep your trebuchet on the ground, and don't get blown up by your own earth-shattering thunder. ”

Li Yanqing has been dealing with trebuchets for so long, he is also half an expert, after all, trebuchets are made of wood, although they are powerful, they are also easy to damage, especially this super giant trebuchet, it looks majestic, but in fact it is even more unreliable, it is okay to throw earth-shaking thunder once or twice, and there will be danger if there are more, Li Yanqing must let these craftsmen stay and observe the condition of the trebuchet at any time.

The overseer next to him smiled: "Li Dutong rest assured, even if you didn't say that we would stay, this thing is the first time everyone has made it, there is no bottom!" ”

"That's good!"

Li Yanqing immediately let the soldiers disperse, he walked quickly up the city wall, at this time, twilight had quietly fallen, the sun had already set, but the sky was still a pale cyan color, and the 'pyramid' in the distance was shrouded in a layer of black mist, but the outline could still be seen clearly.

At this time, a slender item appeared on the pyramid, Li Yanqing squinted for a moment, it seemed to be a piece of wood, but this pyramid has not been completed, what is the wood to do?

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

I was mistaken, the other party is going to build a platform, of course there will be no more spires, it must be a flat top, I always think about the pyramid, I actually misled myself, needless to say, the other party is now hanging a big log, it must be building a trebuchet.

At this time, Liu Jian walked forward quickly and said: "The humble post is about to report to the capital, the other party has built a high platform, and now it should be building a trebuchet." ”

Li Yanqing nodded, he didn't want to tell his subordinates that he was blind, so he ordered his own soldiers, "Go and find Supervisor Wang." ”

Supervisor Wang's name is Wang Hui, he is the chief master craftsman of the crossbow workshop, a little old man in his fifties, he is in charge of supervising the construction of the super trebuchet, and after a while, Supervisor Wang hurriedly came, "What are the orders?" ”

Li Yanqing pointed to the flat-topped pyramid in the distance and asked, "The other party is hanging wood now, it should be building a trebuchet, I want to know, how much time will it take them to build it?" ”
