Urn City, Hou Tower.

Huangfu Song and his generals arrived on time.

Su Yue will talk about the law of change in the formation of the mechanism that he has found in detail.

"The rail road is criss-crossed, all over the streets and alleys of Yecheng. Each 'trap' in the array can move up, down, left and right, in all directions. It is a 'Tian' shaped trajectory. With so many 'organs', there must be 'cardinals' in the middle. ”

Huang Fusong understood: "The so-called 'cardinal' is like the 'order flag' of the military array. ”

"Yes, yes." Su Yue nodded slightly: "The organ formation is also a military formation." It is nothing more than replacing the soldiers and horses in the formation with all kinds of weapons. Soldiers and weapons are hidden in the mechanism to kill the enemy. ”

Huangfu Song can see through one point: "Just break through the heart of the formation and destroy the 'cardinal', this formation will be self-defeating." ”

"Exactly."

After pondering for a moment, Huangfu Song said again: "Dare to ask the chief officer, how to find the 'cardinal'." ”

Su Yue said: "The general is calm and don't be impatient, and listen to me slowly." ”

"This array is all over Yecheng. It is not an exaggeration to say that it is a city of organs. The thieves consumed all the iron in the city in one winter, just to cast the 'rails' and 'organs'. The organs that walk on the track are divided into five categories: attack, defense, trapping, obstacle, and confusion. Corresponding: floors, walls, que, miscellaneous, doors. The so-called high and low shots, all watchtowers, corner towers, warehouse towers, and the like, are all hidden killing machines, and they are 'attacking weapons'. All walls, walls, domains, and fences are all 'guards'. Whoever sees a high tower on both sides, there will be heavy soldiers around it, and it is a place where a trap is set, so it is called a 'trap'. Anything that obstructs the passage of baggage, wooden boxes, sacks, pyrewood, groceries, etc., is an 'obstacle'. Where you encounter the house door, the inner door, the Lu door, the city gate, the lane door, are not entered, this is the 'confusing device', the direction of the entry is lost, and the square inch will be chaotic. ”

"Attack, defend, trap, obstacle, confusion; Floors, walls, que, miscellaneous, doors. Huang Fu Song took it to heart, so he asked: "But where is the 'cardinal' hidden?" ”

Su Yue nodded lightly: "The so-called order is forbidden, and the 'cardinal' is to dispatch in the middle and give orders." In this way, all the organs in the array can operate properly and without mistakes. Analogous to a military formation, the one who conveys the order is either a command flag or a horn. Such as chirping and wolf smoke, after all, they can't escape the word 'sound and light'. The general may wish to think for a moment, did he hear strange sounds or see unusual lights when he rushed into the city that day? ”

Huangfu Song shook his head: "I have never heard of it, and I have never seen it." ”

"That's what we can't figure out." Su Yue frowned and said: "With such a large array, how can you transmit news to each other, so that you can toss and turn, like an arm command, seamlessly?" ”

While pondering, a lieutenant suddenly spoke: "Returning to the general, it is intermittent to hear some out of tune in the sound of the piano. ”

"Oh?" The speaker has no intention, but the listener has the intention. Su Yue asked urgently: "Did you really hear the sound of the piano?" ”

"You can't be wrong." The captain said: "My little sister is quite fluent in pronunciation, and she knows a little bit about it. But what I heard in the city that day was intermittent and did not form a tune. ”

"In this way, the inferior have heard of it." Several lieutenants spoke one after another.

Thinking about it carefully, Huangfu Song also nodded: "There is indeed the sound of the piano." As everyone said, it is intermittent and uncome. Therefore I did not listen carefully. ”

"I see." Su Yue said with a smile: "No wonder there are no flags, bronze mirrors, ringing didi, and so on in the city." The thief uses the 'same kind of movement' to communicate the ear! ”

"What is 'like-like motion'?"

"'Homogeneous motion', also known as 'harmony with the same law'." Su Yue was about to elaborate, but suddenly sold a pass: "This city can be broken!" ”

"I want to hear about it." Huangfu Song hurriedly clenched his fists.

"The general only needs to be so ...... so"

Counting out the chief officials of the Ji Kingdom, Huangfu Songyan can not believe it: "Thank you Changshi for your help." The city must be grateful. ”

Su Yue returned the salute solemnly: "It's all for my Han Guozuo, and the lower officials don't dare to say thank you." ”

Without further ado, Huangfu Song went to prepare for war.

Su Yue summoned Dian Wei and said in his ear: "Tomorrow, we will wait and enter the city with Zuo Zhonglang." Zhonglang will be in the light, and I will wait in the dark. While the Yellow Turban Thief and Zuo Zhonglang were fighting, they had no time to care. Disguised as a group of Yellow Turban thieves, we searched for the location of the 'cardinals' in the city. This is a strategy to capture the thief and capture the king. ”

"Hmm!" Dian Wei nodded roughly: "Looking for the 'cardinal' is bothering Su Gong." Kill the thief chieftain and hand it over to so-and-so! ”

"Okay." Su Yue smiled happily.

That night, several amphibious vehicles landed from the port. Pulled by oxen into the urn city.

Early the next morning.

The gate, full of the flesh and blood of the thieves, slowly rises. Huangfu Song is a man with horse armor and a shield. The knights of the Three Rivers were led to escort several machine cars, and the fish came out.

"Drumming!" Huang Fu Song gave an order, and the sergeant in the car immediately moved the spring.

The drums of war rumbled in the car. The name of this car is "War Drum Boat Car". Originated from the Jili drum car. It's just that compared with the Jili drum car of "beating the drum for one mile and ringing the bell for ten miles", the wheel of the "war drum boat" can beat the drum once every turn, which is driven by the animal power in the car, and can beat the drum and sound the gold all day long.

Several boats rang at the same time. For a while, the sound of drums shook the sky and was deafening. Both inside and outside Yecheng can be heard.

It was so noisy, but there was dead silence in the city.

"The attack and defense are trapped, and the walls of the building are chaotic." Huangfu Song silently recited the cross mantra and waved his sword: "Kill!" ”

"Kill—" The Knights of the Three Rivers raised their shields and ran up with a kill.

Seeing the Han army rushing towards him, the mechanism that was integrated with the buildings in the city immediately shot random arrows. but was blocked by the knight's shield and equipment.

"Arson! Huangfu Song roared angrily. The man borrowed the speed of the horse and threw the oil urn in his hand vigorously.

Knights followed suit. A device disguised as a city building was splashed with oil.

The rocket came from behind, and the trap burst into flames.

As Su Yue said. In order to reduce weight, the mechanism is mostly made of wood. Just in time for arson. And in just one winter, the thieves couldn't forge enough enamel armor pieces to resist rockets in their busy schedules.

In the blink of an eye, the five-story market building was burned into a large torch. Smoke billowed out, and the Yellow Turban wrestlers hidden in it were on fire. The ghost cried wolf and jumped from the top of the building. Fragmented, brains burst and died, abound. Many were choked to death by the smoke before they could escape.

The houses and institutions in the city are real and fake. Spliced with each other, forming a whole, there is no way to distinguish.

But it is impossible for the entire house and a street to be full of organs. It must have been a wall, a building, a door, something like that, that has been transformed into a mechanism.

However, how to distinguish is a difficult problem.

With Su Yue's cross formula, Huangfu Song was able to successfully distinguish between the real and the fake. Do every shot must be targeted. is the key to victory.

Of course. It is also possible to set fire on all sides and burn the entire city to the ground. The problem is that if the city is set on fire, the people of the city will be burned together with the Yellow Turban thieves. Indiscriminate, no different from thieves! After the war, not only did he apologize for his crimes, but also affected his soldiers and soldiers to receive military law.

But then again. If Huangfu Song really can afford the notoriety of "butcher", he will set fire to the city. Burn all the people of Yecheng to ashes. Or when attacking a city again, it will be much easier. Knowing the fate of the people of Yecheng, the people in the city will no longer dare to collude with the Yellow Turban thieves and sit still.

Hearing that the official army is besieging the city, they will definitely flee without mentioning it.

Now, even if he doesn't learn to slaughter, Huangfu Song is making rapid progress.

One after another, the organs disguised as buildings in the city were set on fire by the Han army. The Yellow Turban Lux cried for his father and called for his mother, burned a human-shaped fireball, jumped down on all sides, and died of blood.

Half of the city, thick smoke billowed and obscured the sky.

But in an inconspicuous corner. There was a group of yellow turban thieves, quietly touching a warehouse building standing on the corner of the street.
