Liu Song Hanque

Chapter 401 Knowledge is Power
The manufacture of the bed crossbow is not complicated. It is basically a superposition of kinetic energy, adding more elastic potential energy together and converting it into stronger kinetic energy to drive the bow and arrow to fly out to attack the enemy.

Strong kinetic energy also requires harder materials to withstand, and the arrows used to match the bed crossbow naturally cannot use ordinary crossbow arrows that are as slender as chopsticks.

There is no time to forge heavier arrows now, so Liu Yizhen swung his hand and loaded the spear most commonly used by soldiers.

It's just that the center of gravity of long weapons held in the hand, such as long spears and spears, is at the front of the weapon, and the front-heavy and rear-light structure is not suitable for the long-distance flight of weapons. Block weights balance its weight.

"It should be almost there."

A rush-made bed crossbow combined with a modified spear made their combination look very cheap.

But beauty and ugliness are never the first choice of weapons!

"Get out of the way, let me do it first!"

Pushed the bed crossbow out of the small black room, and asked three soldiers to pull the winch, but found that they couldn't pull the bed crossbow's bowstring at all.

This discovery caused the artisans who helped Liu Yizhen and Xue Andu to make the bed crossbow to look at Xue Andu in surprise.

Because Xue Andu was the only one who wound it inside just now!

In other words, Xue Andu alone was stronger than three ordinary soldiers!

"Humph!"

Xue An completely forgot how he screamed in the small dark room just now, and now he stretched his neck like a proud rooster to accept their praise.

Two more soldiers came, and with the joint efforts of five soldiers, they used the winch to tighten the bowstring of the crossbow on the bed.

The crossbow string that was pulled to the limit was filled with dangerous luster at the moment, and just by looking at that terrifying deformation, one could tell that it contained energy that shocked the world.

And the three ferocious "guns and arrows" on the bed crossbow also showed their fangs, staring at the distant shooting range.

"Get out of the way!"

Once again ordering the soldiers within the attack radius to get out of the way, Liu Yizhen personally stood behind the bed crossbow holding a huge hammer.

To release such terrifying kinetic energy, it is naturally not like ordinary crossbows that can be shot by moving your fingers, but rather requires a considerable amount of energy to pull the trigger to completely release the power of this mechanical monster.

Holding the sledgehammer, Liu Yizhen slowly raised it up to the top of his head, then focused on the trigger of the bed crossbow.

"Give me—go!"

Liu Yizhen slammed the trigger with all his strength, and with an earth-shattering bang, the entire bed crossbow was bounced tens of inches high, and the three arrows on it naturally disappeared.

"Bang bang bang!"

On the shooting range in the distance, several targets piled up with wood were directly blasted, and debris was scattered all over the sky.But the few guns and arrows were gone.

"Your Majesty! General! Here!"

Several soldiers on horseback ran quickly, found the three shot arrows, and reported to Liu Yizhen in pleasant voices.

Liu Yizhen stepped on the crossbow on the bed, stretched his neck to see the position of the gun and arrow, and began to estimate secretly in his heart.

"Almost five hundred steps!"

Five hundred, although it is not as good as the giant crossbow recorded in "Hou Han Shu", which can reach a thousand steps, but it is definitely enough!

Because there is no catapult in the world that can hit five hundred paces!
After all, the catapult is a siege tool, and its kinetic energy will not be completely converted into forward force, but to make the shell do work upwards, which will undoubtedly consume a large part of the converted energy.

But the crossbow does not have this loss, the guns and arrows it sends out are all straight, and they can fly as far as they can, and the range is naturally much greater than that of the catapult.

"Strength works too."

It can shoot wooden targets, and of course it can also shoot wooden catapults.

"There are still some problems with the accuracy."

After all, the bed crossbow was made in a hurry, without a lot of debugging by the craftsman.

Those guns and crossbows were also temporarily modified, and the style was actually very unaerodynamic.

This caused the guns and arrows, which were obviously in the same direction, to fly [-] steps away, one was in the west, the other was in the east, and the other was inserted crookedly between the two.

but……

Who cares?

After seeing the power of the bed crossbow, Yuan Gouzhi's eyes widened. He kept stroking the bed crossbow with both hands, and kept shouting "Miao, Miao."

The eyes of An Jie and Zong Cui, who were observing on the side, also brightened. They looked at each other, feeling aggrieved that they were about to come out but couldn't pierce the layer of paper for a long time.

"It's been said in "Ming Li". After all, the two of you are also scholars who passed the imperial examination. Why can't you even remember this?"

It was Liu Yizhen who helped them pierce the window paper, which made An Jie and Zongxi suddenly realize.

"Having learned the knowledge in this book and being able to use it are completely different things."

As he said that, Liu Yizhen personally explained to them the way elastic potential energy is transformed into kinetic energy and the factors that affect its transformation, and he was short of writing a formula and pasting it on their foreheads.

The two listened fascinatedly, even Xie Hui and Yuan Huzhi, who had never studied "Ming Li", were engrossed, wishing to engrave everything Liu Yizhen said in their hearts.

"I actually thought that "Ming Li" was an enlightenment reading, and I was really looking at the sky from a well!"

There seemed to be shame on the faces of the two of them, while young people like An Jie and Zong Xi looked at Liu Yizhen with reverent eyes.

If anyone says that reading is useless in the future, the two of them will definitely use this bed crossbow to nail the person who said this to the wall.

Reading is useless?Reading is useless, can you make this kind of bed crossbow?
Just when Liu Yizhen was leading a group of graduate students to attend class like an old professor, only Xue An, a low-achieving student, was a little absent-minded and didn't know what to say.

"Xue Andu! Do you understand?"

Xue An, who was suddenly named, nodded quickly, and then saw the familiar smile on the corner of Liu Yizhen's mouth: "Now that I understand, I will entrust you with the task of transforming the bed crossbow!"

"No... huh?"

Under Xue An's shocked eyes, Liu Yizhen directly slapped his ass and walked towards the camp.

"If you can't do it tomorrow, you will be dealt with by military law!"

Xue Andu: "..."

When he turned his head to look at An Jie and Zong Que, they also left shoulder to shoulder and said they were going to help Zhu Xiuzhi and Liu Yuanjing repair the wall.

Xue An looked at Yuan Huzhi, only to see Yuan Huzhi raised his arms and immediately turned his head away, obviously still grieving over Xue An's twisting him forcibly to heal his wounds.

As for Xie Hui...

Staring at the title of "Chen Jun Xie's", even if Xue An was killed, he wouldn't dare to bother Xie Hui!

"They're all bad guys!"

"..."

"They're all fucking bad guys!"

Xue An wanted to cry without tears, picked up a bowstring, and thought carefully with his strong brain.

"What the hell is this thing for?"
