Li Bo's father had a strange face: "This is all Guo Ge'er's idea? He usually looks like he is smiling, why does he have so many strange ideas in his stomach? Even those of us who fight are not as many as his ghost ideas." ”

Carpenter Zhou next to him sneered: "Ghost idea, Lao Li, have you ever seen Brother Guo'er's real ability! Come on, I'll show you a good thing!"

Li Bo's father followed Carpenter Zhou and others to the carpenter's workshop warehouse, opened the door of the warehouse, and saw a few small workers under Carpenter Zhou, assembling a few long wooden poles and a bunch of steel parts.

Without waiting for Li Bo's father to ask, Carpenter Zhou said: "This thing, Brother Guo calls it a cannon, it is a peerless weapon for attacking cities and attacking enemies from a distance!"

In fact, this is a stone thrower, and the principle of the stone thrower is relatively simple, so under the guidance of Guo Dalu, Li Dayan and Zhou Carpenter quickly made a few fights, and secretly dragged them to the open space of the back mountain to try a few shots a while ago.

The projectile used in the stone thrower is not a common stone bullet, but a pottery bullet, which Zhao Kang and other potters use to roll the clay into a round ball and put it in the cellar to fire.

The process of making this clay bullet is much simpler than that of stone bullets, and the weight can be controlled more precisely, making it easier to aim.

The surface of the pottery bullet is hard, and once it is smashed on the ground and shattered into countless pieces, it is like shrapnel, and it has great lethality when smashed on the light infantry without armor protection. Even if an enemy is wearing armor, if he is hit by such a bullet, he will suffer from an internal wound and vomit blood.

This stone-throwing tool is not dragged by manpower, but similar to the seesaw structure, one end is the bamboo basket where the pottery bullet is placed, and the other end is placed on the accurately measured steel block, when casting, first use manpower to pull the end of the bamboo basket to the end, buckle it with a mechanism, and then place the pottery bullet, according to the direction of the enemy, load the steel ingot of different weights at the other end, and then aim at the direction of the enemy, hit the mechanism with a sledgehammer, the end of the stainless steel ingot sinks suddenly, and drive the pottery bullet at the other end to be thrown out.

This kind of shooting method, although a little more complicated, but can be relatively accurate aiming, Guo Dalu after the test firing, but also compiled the most coarse shooting table, different distances, how much weight of steel ingots to place, direction and angle, there are references. Although this cannot be compared with the modern artillery firing table, it is already an absolute high-precision weapon in the Great Li Dynasty.

Seeing these unheard-of militaristic weapons, Li Bo's father was even more confident in defending Houlong Village.

Outside Houlong Village, Yu Dazhong was commanding his subordinates, shouting all the way, not like an army, but like a circus, only to see the people under the palace gate and the rivers and lakes holding high the pine torches, crowded at the front, the monsters guarded Yu Dazhong in the middle, a few little demons howled while walking, only the Fanren mercenary group marched quite strictly, and was in the final battle.

Yu Dazhong has been pampered since he was a child, and he is a rice worm to say that it is ugly, where does he know what is the way to march and fight, if it is not for the bearded businessman to remind him, he doesn't even know that he should set up an ambush on the mountain road leading to Yinxian County in Houlong Village. In his opinion, as long as he took these horses and horses, rushed into Houlong Village in a swarm, and slashed and killed, everything would be done.

It's a pity that the girls in Houlong Village are all bigfooted, which is really not in line with Yu Dazhong's taste. Such a big-footed girl is sold to a brothel, and no one wants it, at most she will be a rough girl. Yu Dazhong has seen several female dolls of Li Ruhai's family, what kind of big girl and second girl, they look a little beautiful, but when they look at the big feet under the cloth skirt, they immediately make people lose their appetite and appetite.

Yu Dazhong's mind was full of dirty thoughts, and the bearded man next to him suddenly said: "Palace Master Yu, cross the small hill in front of you, it is Houlong Village, do you want to reorganize the team?"

Yu Dazhong waved his hand indiscriminately: "What kind of team, just rush over." ”

The bearded man was about to say a few more words, when he suddenly felt something strange under his feet, and he held up the torch to shine a photo, but saw that there was a large white circle on the ground, and in that large circle, there was a white dot, but he did not know what it was used for? He half-squatted down, touched the white thing, but found that it was lime.

This white circle and white dot are like an extremely large arrow target, encircling half of the centaurs in it.

The bearded man was stunned, what is this thing for? Is it the ghost of the people of Houlong Village?

He turned his head and whispered to the mercenary leader, "Be careful, step back." ”

The mercenary leader nodded and gestured, and the mercenaries under him quietly took a few steps back, leaving the white circle range.

At this moment, when I heard a whirl, something crossed the top of everyone's heads, and with a bang, it smashed on the ground, and suddenly a burst of rubble splashed everywhere, smashing on the bodies of the people leaving the palace and the people in the rivers and lakes, and everyone drew out their swords and brandished, "What the hell?" "Ouch, my body hurts so much, I bleed! I bleed!" "It's rubble! Someone threw gravel at us!"

Everyone held torches and took a burst of random photos, but they did not find any sneak attackers, only to see some broken pottery shards scattered on the ground, as if some clay pot had been broken, and it was the ceramic shards that hurt people, the edges of the shards were extremely sharp, and the people who were hit were cut out of large and small wounds.

Everyone was disturbing, and behind the hill bag, Chen Qingdai and Li Boer were directing the villagers to manipulate the stone thrower.

The second girl was nervously calculating next to her, and she shouted: "The distance is still a little short, increase the weight of some ingots, and correct the azimuth--"

It turned out that the people of Houlong Village used the curved shooting ability of the stone-throwing tool to hide behind the hill bag and attack, and used the trigonometric function and other methods taught by Guo Dalu to calculate the enemy's position and launch an over-the-horizon long-range attack. The white-gray round target on the ground was drawn by Chen Qingdai and used as a reference.

Erniu's math was the best among the children in the Yixue class, and at this time, she bit her lip lightly, frowned and calculated carefully, and soon calculated the new trajectory.

As soon as a few numbers were reported, Li Boer and Chen Qingdai, holding a triangle board, a steel ingot that had been weighed in the morning, and other things, quickly adjusted the stone thrower, and Chen Qingdai waved his hand: "Three salvos!"

Knock knock, sledgehammer hit the bolt heavily, the bolt bounced open, the other end of the steel ingot counterweight, suddenly sank, the other end of the bamboo basket was raised high, the pottery bullet burst out of the air. (To be continued.) )
