Back at the prefect's mansion in Guantao, Guo Jia said to Han Zhan: "Lord, don't look at Yuan Shao's army now stationed in the south of the city, but if we station the entire army in the city, he can surround us, and then our army can only sit and wait for death."

When he heard Guo Jia talk about the issue of food and grass, Han Zhan said thoughtfully: "Yuan Shao's tens of thousands of troops consume a lot of food and grass every day. As long as we send a team of people to plague his food routes. As long as the Yuan army lacks food, the morale of the army will be unstable sooner or later. We take the opportunity to attack it and will be able to fight and win."

"Lord," Zhao Yun heard this and hurriedly stepped out to suggest to Han Zhan: "You can send Han Sheng's cavalry to harass the Yuan army's grain route. The Yuan army's grain transport soldiers were all infantrymen. Even if they were large and powerful, Han Sheng's cavalry could escape unscathed."

"General Zilong said this very well," Guo Jia immediately expressed his support for Zhao Yun's statement. "Prince Huang's cavalry once defeated the Yuan army. I believe that the Yuan army soldiers were afraid of them. If they took action, they would achieve twice the result with half the effort."

Han Zhan agreed very much when sending Huang Zhong's cavalry to harass Yuan's army's food route, but he considered that although Huang Zhong was a powerful general, he still lacked strategy, so it would be great if he could send a counselor to accompany him. He glanced at Guo Jia next to him and immediately denied his thoughts. Not to mention that Guo Jia had to stay by his side and help with advice; even if he could be allowed to attack with Huang Zhong, his small body would probably not be able to withstand the long-distance attacks of the cavalry. If he was tired of it, he would have suffered a great loss.

Seeing that Han Zhan had not made any statement for a long time, both Guo Jia and Zhao Yun seemed a little embarrassed. Both of them thought Han Zhan did not agree with his statement. Just as they were about to retreat to the queue, they suddenly heard Han Zhan asking: "How many days do you think the cavalry should carry dry food with you when they attack?"

"Jia thought it only took three to five days of dry food," Guo Jia quickly replied, "Even if the dry food is exhausted, you can eat it from the enemy."

After confirming the cavalry attack, Han Zhan continued to say: "Fengxiao, to defeat the Yuan army, there must be attacking and defense. Huang Zhengwei led the cavalry to harass the Yuan army's food route, which is considered an attack; if you don't know how to defend, how should you abide by the law?"

"Lord, Yuan's army has not attacked the city today. In Jia's opinion, it must be building siege equipment in the camp. Once the equipment is complete, it will attack in large quantities." Guo Jia said confidently: "Our army only needs to build siege equipment to block Yuan's army's offensive."

Han Zhan knew a little bit about siege equipment, but he really didn't know what the city guard equipment had. So he humbly asked Guo Jia: "Fengxiao, I wonder what city guard equipment we need to build?"

Guo Jia took out a roll of drawings, placed them on the table in front of Han Zhan, and said to him: "My lord, please see, this is the city-guarding equipment we are going to build."

Just as Han Zhan looked down at the drawings, everyone in the hall also surrounded him, wanting to see what kind of city guarding equipment Guo Jia was planning to build. Seeing everyone around the table, Guo Jia began to explain.

The first thing is a car crash. It is a tool used to hit a cloud ladder. A collision rod is tied to the frame, and the front end of the rod is inlaid with iron sheets. When Yuan Jun's cloud ladder approaches the city wall, pushing the collision rod can destroy or knock it down.

The second piece is the fork rod. It can not only resist the Yuan army's use of ladders to climb the city, but also be used to kill enemies who climb the city. When the Yuan army's ladder approaches the city wall, use the horizontal blade in the front of the fork rod to resist the ladder and push it down; or wait for Yuan soldiers to climb halfway through the division, use the fork rod to push and chop down the ladder. The horizontal blade in front of the rod can cut off Yuan soldiers' arms.

The third piece is the flying hook. It is shaped like an anchor, with four sharp hook claws tied with iron chains and then connected to the rope. When Yuan Junyi is attached to the foot of the city and is about to climb the city, he will accidentally jump into the crowd and kill several people at a time.

The fourth piece is Yasha. This weapon uses elm wood one foot thick and one foot long as rollers, and is nailed around it with "reverse beard nails". The nail head is exposed with five inches of wood surface. Wheels with two feet diameter are installed at both ends of the roller wood are connected to the winch. When Yuan Jun gathers at the foot of the city, he throws himself into the crowd and stirs the winch to crush the enemy to death.

The fifth piece is a wolf tooth pat. It is made of elm wood into a dustpan shape, 5 feet long and 4 feet 5 inches wide, with 32oo wolf tooth nails nails on it. The nails are 5 inches long and 6 taels heavy, and the nails are 3 inches out of the wooden surface. The knife with a sharp blade is embedded on all sides, and the knife is 1 and a half inches into the wood. There are two iron rings in front and behind the wooden surface, tied with ropes and hung on the chariot at the city. When Yuan's army attacked the city, they first hang the wolf tooth pat, and then fell heavily to the attack. There are sharp blades on all sides of the pat, which makes the enemy soldiers unable to resist.

After hearing Guo Jia talk about five types of city guarding equipment in a row, Han Zhan finally found a kind of equipment he was relatively familiar with. This wolf tooth patter was quite similar to the nail boards in later generations. Falling from a high place was simply a nightmare for the soldiers siegeing the city.

The sixth type is the door-blocking knife. It is a kind of equipment used to block the city gate when the city gate is broken by Yuan’s army. There are 24 steel knives installed on the front knife wall. When used, push the car into the city gate hole, which can kill the Yuan army and prevent them from rushing into the city.

The seventh type is the flail stick. The flail stick is two wooden sticks, one long and one short, connected with chains or ropes. When Yuan Bing climbed along the ladder to the edge of the city wall, he used the flail stick to hit him, and he could shoot them down from the ladder.

After introducing seven types of city guarding equipment, the civil and military personnel around the table dispersed one after another. Guo Jia stood up and asked Han Zhan: "Master, due to limited time, we cannot make all the equipment. I wonder which ones do you plan to make first?"

Han Zhan thought for a moment, then said, "I think I'll make a batch of fork rods, wolf teeth slap, and flail sticks first." After pausing for a moment, he added, "The Yuan army is powerful, and we cannot ensure that the city gates are not lost. The door-squeezing knives are also made, so we must make at least two in each city gate."

"As for your order!" Guo Jia agreed and retreated and entered the queue.

Although Guo Jia introduced himself to seven types of city-guarding equipment, Han Zhan felt that it was far from enough to block Yuan Shao's attack. He stood up straight, walked backwards with his hands behind his back, thinking about what other killer Yuan Shao would use?

But after thinking for a long time, he didn't think of anything, so he stopped and asked Gao Lan: "Captain, tell me, how did Yuan Jun feel busy when he was sieging the city?"

Gao Lan thought about Han Zhan's question and answered out of the list: "When you say lord, when Yuan's army attacked the city yesterday, they used swords, shields and hands to form a formation under the city, and their archers hid behind the scenes. The dense rain of arrows made our soldiers unable to look at them, so that Yuan's soldiers began to climb the city, so we rushed to fight."

Gao Lan's words reminded Han Zhan of Yuan Shao's battle at Guandu, and he relied on tens of thousands of powerful crossbowmen to defeat Cao Cao's army and fled in a panic. He also piled up soil mountains near Cao's camp, built high platforms, and suppressed Cao's army with arrow rain. Thinking of this, Han Zhan turned his head and asked Guo Jia: "Fengxiao, I remember there is a kind of siege equipment that allows archers to shoot arrows on it. What's the name?"

"Go back to the lord, call me Jinglan!" Guo Jia also showed a grim expression on his face when he heard Han Zhan talking about this kind of siege equipment. He murmured: "The Jinglan is three meters high, and a pulley is installed below. You can shoot arrows on the city wall from a high place while moving to cover the soldiers climbing the city wall."

When Dian Wei heard that Jinglan could actually move and shoot arrows, he couldn't wait to ask Guo Jia: "Mr. Guo, I wonder what kind of city guarding equipment our army can use to deal with it?"

Guo Jia looked at Dian Wei, shook his head gently, and said helplessly: "Person Dian, Jia has no good way to deal with Yuan Jun's well railing."

"The well railing is a moving arrow tower. Although archers can be deployed to shoot arrows around, it also has a fatal disadvantage, which is its slow movement." Although everyone was at a loss, Han Zhan had already taken measures to deal with it: "We can dig pits far away from the city walls and dig them densely, so that Yuan Jun's well railing will not be able to pass."

Regarding the method proposed by Han Zhan, Guo Jia frowned and thought for a while, then raised his own question: "Lord, if the pit dug can block Yuan Jun's well railing, the project volume is quite large."

"The main attack direction of Yuan's army is in the south of the city. We only need to dig more earth pits in the south of the city." After Han Zhan told Guo Jia what he thought, he ordered Gao Lan: "Capital Captain, please organize manpower overnight and dig more earth pits in the south of the city, so that Yuan's army cannot use the well railing to deal with our army."

"I will obey the order!" Gao Lan quickly agreed, "I will take my troops and the people of this city to dig a hole outside the city."

When everyone dispersed, Han Zhan called Guo Jia and asked, "Fengxiao, although Huang Xiaowei is extremely brave, he is still slightly inferior in strategy. I am worried that if Xin Ping, Feng Ji, Shen Pei and others use tricks, he may suffer."

Guo Jia also agreed with Han Zhan’s concerns: “What the lord said is very true. Xin Ping, Feng Ji and others have made great strategies, and Han Sheng is indeed not their opponent.” He said this, stopped and thought for a moment, and then suggested to Han Zhan: “The convoy of Xun Gongda and the Xiahou Captain escort food and grass will be half a day behind us. The lord can send someone to take Xun Gongda here overnight and ask him to send troops with Han Sheng tomorrow. How about it?”

"This is a good idea." Han Zhan nodded repeatedly after hearing this. He turned around and shouted outside: "Come here!"

Following the shouting, Rob walked in from outside, saluted Han Zhan, and asked respectfully: "What are the lord's instructions?"

Han Zhan ordered to him: "Suppose twenty cavalry immediately and rush to the camp of Xiahou Captain overnight, and let Mr. Xun come over overnight. No mistakes are allowed!"
