Liu Wei didn't know that Nanpi's secret had been leaked, and Chen Zhi naturally didn't tell the principal about his troubles, and after getting Xu You, Liu Wei asked him to integrate the forces of the Xu Mansion in case of accidents.

The stunned officials in Yuan's mansion slowly woke up, but they had already been detained in separate rooms, unable to speak to each other, let alone allowed to exchange information, and these officials were stupid and did not know what was going on.

After Liu Wei got the news, he called Lu Yin and whispered a few words in her ear.

Lord, this man has no ability, why do you value him so much? ”

Guo Tu is the blessed general in Liu Bian's heart, so Liu Biao is ready to let Lu Yin find an opportunity to let him go, just like in Dongjun.

"Everyone has their own abilities, and you can't underestimate people." Liu Wei was working on the large Xiangyang cannon recently, so he showed the drawings to Lu Yin, pointing to the dense components and said.

"Everyone is like the parts of this paper, and when these parts work together, the power is terrifying."

Lu Yin pouted, and when she saw that there was no one in the room, she twisted her waist, "Lord, don't be too tired, I've been studying these boring components every night lately, and what about watching Yinyin dance?" ”

Liu Wei remembered his promise at this time, and sweated profusely, so he had to coax Lu Yin softly, asking her to go to Gao Hao and others first to release Guo Tu.

The historical Xiangyang cannon was already terrifying, and the ordinary city could not withstand a saturation attack under the ravages of the Xiangyang cannon.

However, after seeing Huguan, Liu Wei thought that it was necessary to build a more powerful Xiangyang cannon, the kind of Xiongguan built with mountain stones, and it was difficult for ordinary Xiangyang cannons to cause serious damage to it.

Although Liu Wei is proficient in history, he does not know how many passes in the late Han Dynasty were built with whole mountains and rocks like Huguan, and if two or three giant Xiangyang cannons can be built, then there will be no obstacle to attacking the city and plundering the land.

The Xiangyang cannon is so powerful, because the cannon body is set up reasonably, and the gear chain rotates and saves effort, and here it uses the lever and gear technique handed down by several Greek Archimedes.

Archimedes once said, "As long as you use the support skillfully, the longer the lever, the greater the strength, give me a fulcrum, and I can pry up the whole earth!" ”

Such mathematical and mechanical principles, whether Guo Jia, Jia Xu, Zhou Yu or Pang Tong are not proficient, in the late Han Dynasty, only this Liu Wei exclusive, no other semicolon.

As for the interaction between gears, eccentric wheels, connecting rods, and rotating shafts, Archimedes also has a brilliant discussion, focusing on lengthening the barrel and adding linkage gears, which can fire larger stone projectiles and hit farther. ”

However, if the gears are added, it is necessary to fine-tune the mechanical structure of the entire Xiangyang cannon, otherwise the iron chain made of fine iron will not be able to withstand it, and even if it can be used, it is estimated that it will fall apart after a few shots.

Once Jizhou is occupied, Liu Wei's pace of conquering the world will start, build two or three giant Xiangyang cannons, withdraw them to transport them with the army in peacetime, and put them under the city in wartime, which is more deterrent than 100,000 elite soldiers.

I have seen the modern wars in the United States and Israel, science and technology guide the operation, and what tanks, missiles, and the Republican Guard are just floating clouds.

……

Guo Tu was kept alone in a small room, and he didn't know what was going on until now, and he sighed from time to time, and he had the heart to ask the soldiers outside the door about the situation, but no one paid attention to him.

In the middle of his sleepiness, the door opened softly.

Guo Tu was about to get up and was about to speak, but he saw that the person who came was dressed in night clothes, wrapped himself tightly, and pointed to his lips and made a silent gesture.

His heart suddenly warmed up, and Guo Tu obediently stopped moving, and looked at the masked man with hopeful eyes.

"Nanpi has been captured by He Feng of Zhongshan County."

Hearing that it was He Feng's doing, Guo Tu actually smiled, although he had dealt with him several times, but thinking of his glorious impression in his heart, this personal safety should be guaranteed.

Sure enough, I heard someone say softly: "I am under the command of General Wenyuan, immediately send the adults out of the city quietly, don't make a noise, it will not be good to alarm others." ”

Guo Tu thought about Zhang Liao's various kindnesses to himself in Qinghe County, and couldn't help but shed tears and nodded fiercely.

followed the masked man out of the door, and saw several soldiers falling outside, the two of them tiptoed out of Yuan's mansion without much effort.

A carriage was already waiting in the alley outside the mansion gate, and the masked man helped Guo Tu into the carriage and lowered the curtain, which was a long sigh of relief.

"There was no danger, and I finally rescued my husband."

"Tu also often misses General Wen Yuan, and I can't wait to talk to him as soon as possible, and get drunk." Guo Tu said excitedly.

The carriage moved, and the masked man pulled down his mask, revealing a shrewd face.

"In Xia Sui Yu, Mr. will be sent out of the city, Jizhou can't stay, Mr. can go to Qingzhou to join the eldest son."

Guo Tu didn't expect Zhang Liao to help him think of a way out, and he frequently agreed when he heard the words.

"With Yuguanzhi, when Mr. arrives at the eldest prince, he can pay close attention to the situation in Jizhou, once Yuan Gong has something...... The eldest prince became the only backbone of the Yuan family. ”

Guo Tu listened to the blood boiling, He Feng and the lord of the war, this is to fight for Jizhou, the use of means is understandable, once he gets out of trouble, tell the situation to the eldest prince, show absolute loyalty to the eldest prince, this position will be unbreakable from now on.

The third prince must be over, and the dispute between the princes is over, Guo Tu believes that even if He Feng can defeat the lord, he will not be able to swallow the tens of thousands of horses of the lord, and the eldest prince will definitely be reused by the lord in the future.

Thinking of this, Guo Tu couldn't wait to ride on Dapeng and immediately flew to Yuan Tan's side.

……

Letting go of Guo Tu is a nail planted by Liu Wei in the middle of the Yuan group, if Yuan Shao can be completely defeated in this battle, if not, Liu Wei will not be stupid to deal with Yuan Tan now.

Although Yuan Shao lost the battle of Guandu, his strength was not weaker than Cao Cao, and the reason why he was easily pacified by the small eyes was that the two sons fought for power after Yuan Shao's death was the main reason.

If Yuan Shao hadn't died of illness, it was up to him whether Cao Cao could take the north, as long as Yuan Tan, Yuan Shang, Yuan Xi, and Gao Gan did not have civil strife, plus Wu Huan's help, whether it was troops or logistics, Cao Cao was still at a disadvantage.

Yuan Shao died, these two sons had no use value, and Yuan Shao lived, Yuan Tan and Yuan Shang must live, so that Yuan Shao not only could not become strong, but would only slowly decline.

Xin Ping, Feng Ji and these people all like infighting, Liu Wei is ready to see the results of this battle and then deal with them.

……

Chengping, Yuan Shao's camp.

Pang Tong's defense was really good, Chun Yuqiong and Gao Ran led the troops to come, Yuan Shao had more than 20,000 men and horses in his hands, and attacked for several days, and Chengping City stood still.

Guo Jia in the back sent countless small forces to harass the logistics of the Yuan army, which made the Yuan army very nervous, fearing that Guo Jia would suddenly attack the camp.
