Gongsun Xiu participated in Liaodong political affairs, and the second step was to incorporate the Xianbei ethnic groups into the army.

After all, Liaodong was managed by the Gongsun clan for nearly fifty years. Not only did it cultivate a large number of troops, but it also integrated the remnants of Xianbei and Wuhuan into the army to consolidate its own power.

Gongsun Xiu inspected the army as usual and was about to turn over the horse, but found that he didn't know how to get on. Finally, with the help of the little men beside him, he climbed onto the horse's back.

He clamped the horse's belly with his legs. The horse moved gently, and his legs could not be clamped. He fell down directly. The young man hurriedly held Gongsun Xiu and said, "Criminal, why don't you ride a horse?"

"It's nothing serious, I still have to ride a horse."

Gongsun Xiu sat firmly on the back of the horse with his memory, held the reins, and rode his horse around a long circle.

It is rumored that Sima Yi is about to arrive in Liaodong, and he is working hard to build fortifications, building high city walls and strengthening stones.

He stood on the city wall, looked down at the city, frowned and said, "How do the enemy attack the city usually attack?"

Yang Zuo was stunned and then said, "Most of them should not use large-scale weapons such as ladders or cannon stone machines. I have ordered people to speed up the production."

Gongsun Xiu shook his head and said, "I don't mean that. Sima Yi's light army is moving in a hurry. It is impossible for him to carry such a large siege weapon. If he comes in person, it may be the first to make the siege weapon."

“That’s natural.”

Yang Zuo said: "It is extremely expensive for people to eat horses along the way. The cannon stone machine is extremely bulky and cannot be carried, so it can only be made on site."

"How far is the launch distance of the cannon stone machine?"

"The lightest stone is probably three hundred steps away."

Gongsun Xiu nodded: "Three hundred steps? Then we will create a weapon that can reach 600 to 700 steps. He can't hit us, but we can hit them."

Yang Zuo smiled bitterly: "Where are weapons in the world that are 700 steps away?"

The cannon stone machine uses the counterweight of the lever principle, tied stones with the end of the rod tip that is more than ten meters long, ejected when the rope is cut off, and throws the thirty kilograms of stones with huge force to a distance of 300 steps.

Gongsun Xiu looked at the spacious city tower and smiled and said, "Of course, as long as I design something, there is still three months left to allow skilled craftsmen to make the move overnight. When the enemy arrives, they will definitely stop Sima Yi from the city."

Yang Zuo was skeptical, but after all, he was the son of the King of Yan. What he should listen to is that there are 40,000 households and more than 300,000 people in Liaodong. If you want to make weapons, there are a large number of people to recruit.

Companion sea channel.

The endless Wei army braved the wind and dust, flags covering the sky, and the dust raised by horse hooves swept across the sky like a yellow dragon.

The old man sitting on the back of a horse had fairy-like and swaying bones, with his long beards on five lines. His eyes were like eagles and wolves. The generals Hu Zun and Niu Jin around him were both frightened and did not dare to speak.

Sima Yi, who was fifty-nine, turned his horse's head and said to Hu Zun beside him: "Shit the soldiers to throw down all the irrelevant heavy burdens and rush to the road with all their might."

Hu Zun nodded and said, "When the Taiwei returned, he had already unloaded unnecessary supplies and crossed the Liao River. The Liao Tunnel was close to him."

Niu Jindao: "Taiwei, Liao Tun must be guarded by heavy troops. It is better for us to send troops to attack. It will take no time to capture it."

Sima Yi chuckled, with a disdainful look: "For generals, avoiding the real and taking advantage of the weak is the way to use troops. With Gongsun Yuan's mind, he must be waiting for my arrival at the main force of the Yan army stationed in the Liao Tunnel. It is expected that our tired army will travel together in a starry night and cannot last long."

After traveling 30 miles a day, the Wei army was tired and difficult, but there were no large amounts of injuries, staff reduction, and local conditions. The Wei army was basically intact, but the place in Liaodong was harsh, with swamps and dangerous shoals everywhere, and thousands of people were still reduced in the middle.

Niu Jindao: "What Taiwei means is that you can't attack forcefully?"

Sima Yi said lightly: "Attacking Liao Tunnel, you cannot attack in real time. You can lead a partial army to pretend to attack and test it. If the main force of the Yan army is dormant in the Liao Tunnel, you will actually mobilize troops to attack Xiangping. Gongsun Yuan was panicked and would choose to fight our army to be captured alive as if he was on his palm."

Niu Jin and Hu Zun were convinced and admired Sima Yi's scheming.

Sima Yi looked up at the sky and sighed: "I just hope the war will end soon."

Since Zhuge Liang passed away, Shu Kingdom stopped the Northern Expedition for nearly four years. Gongsun Yuan rebelled and relied on his own, threatening the border of Wei. Under the coveted eyes of Shu and Wu, the two countries were unable to make any moves.

Now that the opportunity is ripe, Cao Rui believes that since he ascended the throne, nothing has been recorded in history books, so he transferred Sima Yi from Chang'an to Luoyang, leading 40,000 infantry and cavalry to conquer Liaodong to show his power.

As a veteran of the three dynasties, Sima Yi has become the most trusted old minister besides the Cao clan. Otherwise, he would not have been expeditioned to Liaodong at the age of 59.

In Liao Tun City, under the guidance of Gongsun Xiu, the craftsmen completed a bed crossbow.

Of course, he is not a mechanic master. He has completely seen the shape of the Northern Song Dynasty bed crossbow. The explanation of the two hands and paintings and comparisons is implemented step by step by step by craftsmen.

There are three bows on the crossbow on the bed, two are positive and one is negative, the two are positive and the two are positive and the back are negative, and each other is twisted. The arrow is almost no different from a spear, and it cannot be pulled by human power. Instead, it is used to pull the bowstring with a winch, which requires three people to operate at the same time.

Yang Zuo was curious: "Criminal, how did this be used? Can it really kill the enemy seven hundred steps away?"

Gongsun Xiu smiled and said, "You will know it after a try."

Looking for an empty environment, two soldiers turned the winch and pulled the three hard bows completely apart, and the other soldier buckled the huge arrowhead.

The three of them slapped the crossbow with their hands at the same time. With a loud "collapse", the arrows cast like a meteor, leaping one hundred steps, two hundred steps, and three hundred steps in one fell swoop. The force almost did not weaken, and flew straight for seven hundred steps away, and inserted heavily on the earth wall.

Yang Zuo opened his mouth wide and said in disbelief: "This bow is too powerful. Not to mention Lu Cai, even if it is an enemy soldier and horse, he will be penetrated by an arrow."

The archer's range is 200 steps, and the stone siege machine for heavy siege weapons is 300 steps away. This bed crossbow weighs only about 100 kilograms, and the position and carrying capacity can reach 700 steps.

Gongsun Xiu smiled and said, "This is not counting, there are even more powerful ones."

Three soldiers were asked to push the bed crossbow forward three hundred steps, and fired arrows at the earth wall one after another, and fired them at close range, and entered the wall several inches deeper. They shot more than twenty arrows at the earth wall in one breath, and the earth wall was like a hedgehog.

Yang Zuo could not see anything and looked at the prince in confusion. Gongsun Xiu approached the earthen wall, stepped on the arrow inserted into the earthen wall with his feet, and took advantage of the opportunity to grab the arrow above, and climbed into the air by two in three or five times, jumped down gently, and said with a smile: "If you attack the city, this is the best ladder."

Yang Zuo was surprised and happy: "This kind of magical object is really a skillful trick. If it is used to defend or attack the city, it will be invincible."

Gongsun Xiu developed the first bed, which took nearly a month of careful polishing and six trials to complete.
