Liu Bei took Guan Yu and Zhang Fei to leave the white horse.

Zhao Yun got the news and led the soldiers to leave Yecheng and go with them.

Regarding Zhao Yun's departure, Yuan Xu always felt as if something was missing.

secretly installed Hu Ban, and he was also worried that if Zhao Yun made a mistake by Liu Bei's side, someone would take care of him.

Yuan Shao's military order has been issued, Yuan Xu did not delay much, and led the White Horse defenders to Guandu.

Cao Jun built a thunderbolt car, and Yuan Xu was still on his way to Guandu.

On the dirt slope, feathered arrows shot from the towers.

The archers of the Yuan army aimed at the Cao army within the range, and the arrows were almost missed.

Cao Jun was shot by a bow and arrow, and he didn't dare to raise his head.

Some of Cao Jun just wanted to look up at the tower, and they were shot through the head.

With their bows and strings, the archers of the Yuan army were shooting comfortably, and more than a dozen strange-shaped carts appeared in front of them.

The cart was crawling on the ground, like a giant scorpion, with a long tail in tow.

In addition to this, the sides of the car are spread out like wing-like partitions.

Most of the arrows fired by Yuan's army at the cart were blocked by partitions.

Cao Jun, who was pushing the cart, hunched his waist and marched forward step by step under the cover of the partition.

Seeing that he was only half a shot away from the tower, Cao Jun stopped.

The Yuan army on the tower kept firing arrows, and from time to time one or two arrows fell from the Cao army behind the car.

The big car launched by Cao Jun is the thunderbolt car built by Guo Jiadu.

Although the shooting accuracy of this car is high, the range is greatly limited due to the short power arm.

The two sides lined up their troops, and the thunderbolt could play a great role, but it could only look at the city and sigh when attacking the city.

The towers of Yuan Jun are mostly made of wood. Although the range of the Thunderbolt is short, the accuracy is accurate enough!

You only need to advance a certain distance to collapse the tower.

The archers of the Yuan army on the tower did not know the power of the thunderbolt.

One by one, they put their arrows on the bowstrings. Aim at Cao Jun to launch.

Cao Jun, behind the thunderbolt, put the boulders on the catapult. Aim at the Yuan Jun Tower and project it.

The boulder roared out and crashed against the tower,

How the timber-framed towers withstood the bombardment of boulders.

With the sound of wood cracking, the tower collapsed.

Watching the battle from afar, Yuan Shao was taken aback when he saw the towers collapsing under the bombardment of Cao Jun's boulders!

"What is this?" Pointing to the thunderbolt in the distance, Yuan Shao asked.

"The fifth prince built a catapult in Qingzhou." Guo Tu said: "This thing is quite similar to it, but it is much shorter, and it can be pushed forward compared to a catapult!" ”

"Cao Jun has this thing. How can our army match it? Yuan Shao said: "Quickly send an order to Xianxin, asking him to come to Guandu as soon as possible, without any delay!" ”

A Yuan soldier left in response.

Baima is not very far from Guandu, and when Yuan Shao gave the order, Yuan Xu was less than 100 miles away from Guandu.

Knowing that Cao's army had used strange weapons, Yuan Xu didn't dare to delay at all, and urged the horse to speed up.

By the time he arrived at Guandu, Yuan's towers had been destroyed, and only piles of broken timber remained on the dirt slope.

Cao Jun uses a thunderbolt. Yuan Shao didn't dare to underestimate it, and immediately arranged troops to defend it.

Seeing the collapsed tower on the dirt slope from a distance, Yuan Xu entered the barracks and asked where Yuan Shao was. Rushed straight over.

"Father!" Seeing Yuan Shao, he bowed down and made a big salute.

"It's just in time!" Hearing Yuan Xu speak, Yuan Shao pointed at the soil slope: "Cao Jun launched the ancient monster thing today. Destroy all the towers of our army. ”

"Dare to ask my father, how is this thing?"

"From afar. Like a giant poisonous scorpion. Yuan Shao said: "The scorpion tail can throw boulders, and the tower is destroyed by boulders!" ”

"What is the distance of the stone?" Yuan Xu asked again.

"Not far!"

"That being the case. This thing will travel! ”

Yuan Xu didn't see the thunderbolt, but he could tell its characteristics, Yuan Shao asked, "Is there a way to break the enemy?" ”

"Institutions should be systematic!" Yuan Xu said: "Since Cao Jun has launched this thing, our army can also build a mechanism to destroy it!" ”

"Catapult?" Yuan Shao asked.

"Father Mingjian!" Yuan Xu said: "The catapult arm is too long, although it can project boulders remotely, but it has no accurate head. It's not a great thing to deal with! ”

Yuan Shao didn't ask any more.

From Yuan Xu's words, he saw that there was a way to deal with it.

"Leave everything to Xian Xin!" Yuan Shao said.

"Thank you, father!" After thanking him, Yuan Xu immediately returned to the barracks and drew a map of the mechanism.

The thunderbolt was put into the battlefield, and the Cao army advanced all the way, but the Yuan army was fortified everywhere but was unable to resist at all.

The situation on both sides has almost fundamentally reversed.

The Yuan army, which had a large number of people, was powerless to fight back under the advance of Cao's thunderbolt car.

The news of Yuan Xu's arrival in Guandu soon reached Cao Cao's ears.

At the beginning of the Qingzhou battlefield, Yuan Xu took the lead in using catapults, and Cao Cao certainly did not dare to underestimate it.

He immediately gathered the people to discuss what to do.

"Yuan Xianxin came to Guandu, with his whimsical ingenuity, or there is a way to break my thunderbolt, what do you think should be done?"

"Cao Gong!" Guo Jia got up and said: "The thunderbolt is a sharp weapon for marching, and it is not easy for Yuan Xianxin to break it. ”

"What Feng Xiao said is true, but it's just ......"

Cao Cao said for a long time and didn't say any more.

It has been a long confrontation with Yuan Jun at Guandu, and Cao Jun has always been on the defensive.

Before the Thunderbolt was put on the battlefield, Cao's army had several counterattacks but never returned.

Yuan Xu came to Guandu, in case he broke the game, it would not be an overnight thing for Cao Jun to find his advantage!

"If Yuan Xianxin has a way to break the thunderbolt, he has his own way to deal with it!" Guo Jia said: "Master Zun once passed on some craftsman skills, and it has always been useless to fight, but this time he can help Cao Gong!" ”

With Guo Jia's words, Cao Cao was relieved a lot.

"The matter of the construction agency is not too late!" Cao Cao said: "Fengxiao is another artifact, which can be made in advance in case of emergency!" ”

"No!" Guo Jiaying is done!

Back in the barracks, Yuan Xu pondered a way to break the enemy.

From Yuan Shao's account, he has a general understanding of the performance of the thunderbolt.

He also found Yuan Jun who had escaped from the battlefield and inquired in detail about the projection effect of the thunderbolt, and Yuan Xu knew that this object could throw boulders while traveling.

It's not difficult to build a thunderbolt of the same performance, but it's hard to build a mechanism that restrains him.

After thinking about it again and again, Yuan Xu finally picked up the pen and drew it on the paper.

The curtain was lifted.

Yuan Shao entered the tent accompanied by several staff members.

Hearing that someone had entered the account, Yuan Xu raised his head.

Seeing that Yuan Shao was coming, he hurriedly put down his pen and greeted him.

Bowing down, Yuan Xu said: "I don't know if my father is coming, and the child has not been far away, please forgive me!" ”

"I just came to see if there was any way to break the enemy." Yuan Shao said and came to the table.

Picking up the half-drawn drawing, he asked Yuan Xu, "What is this?" How to defeat the enemy? (To be continued.) )
