He Nan and his subordinates took the first step to say goodbye and left, Taicang Cheng Yang Gao and Xu Yaren returned to Qingfeng Restaurant, they went up to the third floor, pushed open a door, and there was a person sitting in the room, Huo Ran was Zhang Hu, a member of the Intelligence Department.

"How's it going, did the other party inquire?" Zhang Hu asked with a smile.

Zhang Hu had already discovered that someone was secretly inquiring about Taicang's grain storage, which was by no means something that ordinary people should inquire about, and his intuition told Zhang Hu that this was very likely to be Jinguo's intelligence scouts looking for intelligence, after all, the real inventory of Taicang's grain was an important secret that only Xiangguo could know.

Zhang Hu set up a trap and arranged for Xu Yaren to brag about his relationship with Taicang, and sure enough, he lured the other party out.

Yang Gao nodded, "The other party asked how much grain there was in stock, but I didn't answer." ”

"Who is the other party, have you investigated?" Zhang Hu asked Xu Yaren on the side again.

Xu Yaren scratched his head and said: "The other party's surname is He, he said that he is a grain merchant, I don't feel like it, I basically know all the grain merchants in the capital, and there is no one surnamed He." ”

"Where do they live?" Zhang Hu continued to ask.

"The surname He didn't say it, but his subordinates said it once before, it seems to be in the area of Daxiangguo Temple."

Zhang Hu was in his heart! With a jump, a carrier pigeon quickly flew past his mind, "surnamed He, Daxiangguo Temple..... ' Zhang Hu muttered to himself, he seemed to think of something?

Bowing his head and pondering for a moment, Zhang Hu slowly asked, "Did the person surnamed He say where he is from?" ”

"He said he was a grain merchant in Zhendingfu."

A smile appeared at the corner of Zhang Hu's mouth, sure enough, he was from Zhending Mansion, why didn't the shopkeeper of the inn want to change places? Probably because the accent is not easy to change.

Zhang Hu nodded, "You continue to go back and wait, it is estimated that they will come to you tomorrow and the day after tomorrow, and listen to my arrangement when the time comes!" ”

.......

A quarter of an hour later, Zhang Hu appeared in Li Yanqing's official room, generally speaking, since Zhang Hu had been seconded to Li Gang, it would be difficult for Li Yanqing to interfere in intelligence matters through Zhang Hu, but this time, Li Yanqing decided to directly intervene in the Intelligence Department and set up Li Gang.

Li Gang's political achievements are to explain to the Son of Heaven, and what he Li Yanqing wants is to put a long line to catch a big fish.

After listening to Zhang Hu's report, Li Yanqing smiled slightly: "Some things can't be based on feelings alone!" You should still make sure, if it's not the innkeeper, wouldn't it be a joke? ”

"Misdemeanor, this arranges people to identify!" Zhang Hu was really a little ashamed, he actually made a mistake in the key link, and he was still the intelligence leader.

Li Yanqing nodded and said, "It's okay to identify, but you can't startle the snake!" ”

"Humble duty understands!"

After a pause, Zhang Hu asked again: "If it is indeed the shopkeeper of He, should he be arrested directly?" ”

"What do you think?" Li Yanqing asked rhetorically.

Zhang Hu shook his head, "Don't be too alarmed, in case there is a fish that slips through the net, it will be troublesome." ”

"It's good that you understand, now we'll just do one thing, be patient."

"Don't bother the capital with your humble position, and leave first."

"Go ahead!"

Zhang Hu retreated, and when he walked to the door, Li Yanqing added: "Block the news strictly, I don't want Li Gang to come to me." ”

"Obey!"

Zhang Hu saluted and left in a hurry.

Li Yanqing came to the door with his hand, he is most concerned about now is not the meticulous work of the Jin soldiers, but the 'pyramid' built by the Jin soldiers, in just two days and one night, it has been built to a height of two zhang, and the terrain in the northwest corner is already high, and now the top of the tower has been flush with the city wall, and then repaired, the Jin soldiers really have to be condescending.

But how to deal with this pyramid, Li Yanqing has not thought of the best solution, Liu Jian suggested that a high platform should also be built in the city, this is a way, but it is too time-consuming and laborious, but Liu Kuan's proposal made Li Yanqing think of a way, although it is not the best, but at least it can be used.

"Is there any news from Young Eunuch He?" Li Yanqing turned around and asked the soldiers.

"No news yet!"

Li Yanqing thought for a while and said, "Prepare the horse, go to the ordnance prison!" ”

.......

Ordnance supervisor is the Song Dynasty is responsible for supervising the manufacture of weapons official institutions, subordinate to the east and west workshops, and the states are in charge of making weapons, flags, tents, things and other weapons and military materials, half an hour later, Li Yanqing and the ordnance supervisor He Fang appeared in the west workshop near the Chenzhou Gate, the west workshop is also called the crossbow workshop, is the ordnance supervisor is responsible for the manufacture of bows, crossbows and arrows and a variety of large-scale defensive weapons of the special office, there are more than 3,000 crossbowmen below.

After the outbreak of the war, the western workshop was working day and night to produce a large number of defensive bows, divine arm crossbows and various large-scale defensive weapons, He Fang took Li Yanqing into a compound covering an area of at least ten acres, which was a workshop for the production of trebuchets.

Although it was night at this time, the courtyard was lit with torches all around, illuminating the courtyard as if it were day, and the parts of various trebuchets were piled up on both sides of the wide yard, and in the middle of a wide open space of four or five acres, hundreds of craftsmen were busy assembling a huge trebuchet, which was the most in history, larger than the giant trebuchet of the Jin Kingdom, with a body size of up to four zhang, and the core of the trebuchet was a throwing rod, which had great toughness and could not be broken.

The throwing rod of this super giant trebuchet is made of an old bamboo that is six feet long, and the workmanship is very complicated, first peeling the bamboo into a uniform thickness, and then soaking the fine scorn in oil repeatedly, soaking it until it is no longer deformed, no longer cracking, and then the first step is completed.

This process alone takes nearly a year, after a year, the strip is taken out, dried in the shade for several months, and then glued with the best glue paint to the thickness of the mouth of the large bowl, and then the outer layer is wound with hemp rope after drying, until the hemp rope is dry, coated with raw lacquer, and then repeatedly wrapped in kudzu cloth, coated with paint, an excellent throwing rod will take at least three years to complete.

He Fang pointed to the three thick throwing rods on the ground and said to Li Yanqing: "It's also good luck, these three throwing rods were made more than ten years ago, and the throwing rods like this one have not been used because they are too long, and they have been placed in the warehouse for more than ten years, but I didn't expect them to be used this time." ”

Li Yanqing said with a smile: "It's because Young Eunuch He remembers that there are these three throwing rods, so he promised me, right!" ”

He Fang smiled and nodded, "It's easy to make a shelf, the key is to throw the pole, and I immediately thought of these three poles." ”

"How far can I throw it after it's made?" Li Yanqing asked again.

"If it's a sky-shattering thunder, it can probably throw about five hundred steps, but it will take at least a hundred people to pull it."

Li Yanqing showed a satisfied look in his eyes, he patted the already built shelf next to him, and said with a smile: "The three trebuchets should be no problem tomorrow!" ”

He Fang ran to ask the supervisor, and came back and said to Li Yanqing: "I asked the supervisor, I still have to install the wheels tonight, put on the pole tomorrow, and debug, and probably it can be completed tomorrow night." ”

"Can all three be done?"

"It should work!"

Li Yanqing was very much looking forward to it, if it could be completed tomorrow night, then they would be ahead of Jin Bing.

........

The next morning, He Nan was pacing back and forth in the courtyard, there was a slight movement outside, he immediately pricked up his ears, he was waiting for his subordinates to ask about the results of last night, his subordinates went out early in the morning, but there was no news so far, which really made him anxious.

At this time, there was a rush of running outside, He Nan hurriedly walked to the gate, and sure enough, there was a rhythmic knock outside the gate, three long and two short, He Nan opened the door, and his subordinates flashed into the yard.

"Why did you go for so long?" He Nan closed the door and asked.

"I went to Taicang with Xu Yaren today, and Xu Yaren went to find Yang Gao."

"And the result?"

Yang Gao was a little hesitant, but he promised to come out for tea at noon, and he was willing to talk to the leader again.

He Nan didn't know the bottom in his heart, and he asked again: "What did Xu Yaren say?" ”

"Xu Yaren asked us to bring three hundred taels of gold, he said that Yang Gao was already a little tempted, if he could see the gold, there should be no problem."

"Where to make an appointment for tea?"

"It's still Panlou Street, but it's the Qingfeng Teahouse next door yesterday."

He Nan thought about it and agreed, "Then let's clean up and set off later!" ”

Half an hour later, an ox cart slowly stopped in front of the Qingfeng Teahouse, there were not many people on Panlou Street at noon, it seemed relatively deserted, most of the restaurants were open for business in the afternoon, due to the siege of the Jin soldiers, the water source of the teahouse was cut off, and the water quality in Bianliang City was not good, so that the business of the teahouse was also relatively depressed.

He Nan carried a wicker box and walked down the oxcart with his subordinates, and the guy hurriedly stepped forward and said with a smile: "Welcome the two guest officers to the small shop for tea!" ”

"We made an appointment, in the private room on the third floor."

"I know, it must be Xu Yaren who booked a room, they have already arrived, two please!"

He Nan and his subordinates walked into the lobby, just as Xu Yaren walked down quickly from downstairs, stepped forward and whispered: "Yang Guanren wants to talk to the shopkeeper He alone about business, and we will wait in the lobby downstairs." ”

He Nan nodded, and said to his subordinates: "You and Xu Yaren wait here, and I will go up and talk to Yang Guanren!" ”

He carried the wicker box and walked upstairs, and the man led the way in front until he came to a private room in the easternmost part of the third floor, "This is it, guest officer, please come in!" ”

He Nan pushed the door into the room, this is the inner and outer coat room, no one outside, he walked into the inner room, couldn't help but be stunned for a moment, only to see two people in the room, he didn't know either of them, one of the strong men stood next to him, and there was a young man sitting in front of the tea table, burly and majestic, He Nan suddenly felt that something was wrong, turned around and wanted to leave, but two big men appeared behind him, holding their arms in their arms, blocking his retreat.

The young man smiled slightly: "If you come, you will be safe, He Shilang, please take a seat!" ”

He Nan's face changed drastically, and he looked at the young man in horror, "You..... Who are you? ”

The young man said lightly: "Under Li Yanqing!" ”
