Five miles south of Yecheng, the Han army camp.

"General Qiyu, General Zuo Zhonglang has entered Wei County, and the sunset can be reached!" Guardian Accounting Notification.

In the past few days, Tian Yan, the capture general who has been sleepless all night, was in high spirits: "I know." ”

"Report! The state of thistle has messengers into the camp. In other words, the water army of Jiguo has entered Zhangshui. is coming to Yecheng. ”

Tian Yan got up suddenly: "Quickly please enter the big tent." ”

"Whoa!"

Suddenly, the messenger of the country of Ji was led into the account: "I have seen the captured general." ”

"Does the Thistle King have a letter?" Tian Yan didn't care about greetings, so he asked.

"Here is the letter." The messenger took the bamboo tube from his bosom and bowed down to hand it to the lieutenant.

The adjutant general confirmed that it was correct, and this was forwarded to Tian Yan.

Break the sealing mud and unscrew the bamboo tube. Take the paper roll and unfold it. Tian Yan was overjoyed: "The Thistle King is really a hero in the world!" ”

The messenger added: "This time I came with the ship, in addition to the three thousand 'Luan Yu Qiu military tents', there is also an embroidered clothier, and there will be five craftsmen in the museum. Solve the mystery of the mysterious bird for the general. ”

"Thank you for the righteousness of King Thistle's help." Tian Yan saluted solemnly.

The messenger replied: "Without further ado, I will return with humbleness." ”

"Send the messenger."

"Whoa!"

Seeing the messenger of the Ji Kingdom out of the account, Tian Yan couldn't help but read the secret letter carefully. I can't help but sigh: "The trick of the Ji Kingdom is unparalleled in the world!" ”

Zhangshui passes northwest of Yecheng. The port had been captured by the Han army. All the ships were burned. Zhangshui has become an insurmountable moat. Therefore, Tian Yan camped in the south of the city. Zuo Zhonglang will Huangfu Song starry night gallop to help. And he set up camp five miles east of the city. It is a horn with the Han army camp in the south of the city. He also dug deep trenches, put antlers and horses, and cut off the escape route of the yellow turban thieves. And there are many knights of the three rivers under the command of Huangfu Song and the elite warriors recruited along the way. If the Yellow Turban thieves really abandoned the city and fled along the banks of the Zhangshui River. All you need to do is the cavalry and wave the army to cover the kill. The terrain on the banks of the river is flat, and how can the Yellow Turban thieves outrun the horses.

At that time, Henan, Hebei and Hedong were called three rivers. "Book of the Later Han Dynasty: Emperor Guangwu Ji Zan": "The three rivers are not clear. Li Xian's note: "Three rivers, Henan, Hebei, and Hedong." ”

Set up the camp, Zuo Zhonglang rushed to meet Huangfu Song.

"The last general, Huangfu Song, has seen the captured general."

"General Zuo Zhonglang, please get up quickly." Tian Yan also hugged his fists and saluted back: "Please take a seat." ”

"Thank you." The sergeant brought the Hu bed, and Huangfu Song sat down. Hu bed, introduced from the Western Regions, is a sitting with hanging feet, and later generations called "Maza", or "marching chair". In wartime, he was dressed in armor, and it was inconvenient to sit, so the Hu bed was used properly.

"I heard that the Yellow Turban Thief casts magic at night, and he can send fire from the sky. I don't know if there is such a thing? After sitting down, Huangfu Song asked.

"It is true." Tian Yan replied with a smile: "Yecheng is majestic, the wall is high and the city is thick. The Yellow Turban thieves did not come out of the door, and defended themselves according to the city. For many days, I tried hard to defeat the enemy, but I found nothing. Five days ago, when I suddenly heard the sound of the spring at the head of the city, a bird swept down, threw a flowing fire, and set fire to the military tent. After the sergeant was killed by an indiscriminate arrow, he actually burst into flames and fell to the ground, and the poison was even more intense. Most of the military camps were burned down, and even the morale of the army fluctuated. ”

Seeing Tian Yan's indifferent expression, Huangfu Song asked, "I don't know if the general has a way to crack it." ”

"Before Zuo Zhonglang came, the messenger of Jiguo sent a letter quickly, which has relieved my anxiety." As he spoke, he handed the letter to Huangfu Song.

"It turned out to be a man hanging under a big wooden luan." Just one word to break through the sky, mysterious and mysterious things, can be immediately revealed to the world.

"No wonder the Yellow Turban Thieves only attack at night. If this thing is released during the day, why should there be a letter from the king of thistle. Tian Yan sneered: "The Yellow Turban thieves pretend to be ghosts, and they confuse the public with their evil words, so they should be killed to prevent future troubles." ”

"What the general said is very true." Huangfu Song clenched his fists heavily: "The last general is at his disposal." ”

"In this way, please Zuo Zhonglang will guard the camp, and when the ship of the Ji Kingdom arrives, you and I will move forward three miles each. Build ladders and ladders to attack the city on a certain day. ”

"Whoa!"

Nothing was said all night.

Early the next morning.

I saw the water army of the Thistle country across the sea, and poked out of the horizon far away. It rose swiftly again, and was furious in the wind. The Yellow Turban defenders at the head of the city all whispered and looked frightened. The strength of the thistle king, why not say more.

The defenders of the port hurriedly moved the water to block the boats and ships, and let the fleet of the Thistle Kingdom enter the port.

Tian Yan also sent elite cavalry to escort the convoy to meet him. The port is five miles away from Yecheng. If the Yellow Turban thieves dare to go out of the city, they may not be able to fight. But I can see it from afar, but I can't go out. Let the convoy unload the goods and transport them safely back to the camp.

The people on the boat also rushed to meet each other.

"I've seen two generals." The embroidered clothes officer clasped his fists and saluted.

"Strong men are exempt." Tian Yan smiled and said, "Thank you for me." ”

Shi Chang did not leave in a hurry: "When the lord came, I was ordered to pass on the message to the general." ”

"Hurry up."

"The lord said, 'There are also those who are proficient in tricks among the Yellow Turban thieves. The big wooden luan is just one of them, and there must be many sharp weapons hidden in the city. The general must not be left unguarded. In addition, Yecheng is towering, and the moat leads water into it, which is difficult to cross. The well and the ladder are all inadequate. The general may wish to see the model of the various instruments of our Ji State, which may be of great benefit.' ”

"What is a model?" Tian Yan asked.

"Why don't you let the general make a museum and solve the general's doubts." Shi Chang replied.

"So it is, and it is stated in the account."

"Mold, law. Water is said to be the law, wood is said to be molded, soil is said to be typed, gold is said to be Rong, and bamboo is said to be a pipe. A young Confucian scholar, after entering the account, bowed down and replied: "The so-called model is 'imitating its shape with civil engineering'. ”

Seeing that he was full of words, he was very generous. Unlike ordinary craftsmen, Tian Yan asked, "Who is Your Excellency?" ”

Confucian Sheng saluted again: "The mayor of Jiguo, Su Yue, has seen two generals. ”

"It turned out to be the chief of the Ji Kingdom, please take a seat."

"Thank you." After Su Yue sat down, he said again: "Can you present the model of the machine of the country to the general?" ”

"Yes."

Su Yue gave a light high-five. There were artisans of the thistle country waiting outside the tent, and they worked together to carry a lacquered wooden box.

Seeing this, the sergeants in the tent stepped forward one after another to form a human wall. Keeping the two masters in his back, he opened the lid with the Craftsman.

The wooden box was opened layer by layer and decomposed into three cases. Many lifelike miniatures of different shapes are neatly arranged on the desk.

The sergeant picked up the case, looked it up and down, left and right, and confirmed that it was correct, and then placed the case in turn.

"The left is the siege weapons, the middle is the defense of the city, and the right is the field weapons." Su Yue smiled kindly at the two: "Dare to ask the general, do you have something you like?" ”

The yellow turban rebel turtle can't shrink. Defending the city and fighting in the field are not needed. Tian Yan pointed to a model of a mechanism that looked like a warship and asked, "What is this?" ”

"Ladder boat."

"Could it be that there is a ladder inside?" Tian Yan's heart moved.

"Yes, yes." Su Yue nodded lightly.

"What is this?"

"Rush to the city." Su Yue replied again.

After a closer look, Huangfu Song suddenly woke up: "Can it come from the Mozi Beicheng vessels?" ”

"Yes, yes." Su Yue replied with a smile.

Mozi Beicheng Gate lists 12 siege equipment and tactics: temporary chariots, hook carts, rushing chariots, ladders, building trenches (yin, building earth blocks), flooding, assault, cave tunnels, hollow holes (digging tunnels and collapsing walls), ant fu (climbing walls), fénēn (fénēn), and xuanche.

It's just that it's compared to the simple siege weapon created by Mozi. The country of Ji combines the Momen utensils with the unique chariots of the country of thistle. It is a "self-propelled mechanism".

"Did you bring this?" Tian Yan asked, pointing to the 'ladder boat'.

Su Yue smiled and nodded: "It's all on the boat." ”

"Can you demonstrate one or two?"

"Why not?"
