Amina was still a cold and icy beauty. During Amina's process of protecting Louis IX to join the Holy Roman Emperor Frederick II, Holy Roman Emperor Frederick II had already experienced her power.&& At that time, it was her son Prince Eunqi's doubting the effect of the pistol. As a result, after four gunshots, everyone was shocked by the power of the pistol.

When I recalled it, I decided to cooperate completely with Zhao Fubo's Chinese Empire at that time. Although they could not get the weapon, the Holy Roman Emperor Frederick II remembered the sharp state of that weapon clearly. At the same time, I still remember the Amina in front of me, because it can be seen from her cold eyes that she did not mind killing anyone, of course, she might have to besides her lover.

It can be seen that almost everyone was a little afraid of her. At this moment, several weapons were quickly assembled under her insistence. Zhao Fubo began to introduce them to the Holy Roman Emperor Frederick II and his son one by one.

"This is called Caesar's continuous crossbow shooting. If this thing comes here, it will be considered a return to its hometown. It is Roman technology!"

Holy Roman Emperor Frederick II opened his eyes wide and looked at the thing in front of him. Its crossbow body was completely made of bronze machinery. There were two replaceable wooden boxes on both sides of the crossbow shot under the crossbow arm, and the things below were covered by wooden boards and could not be seen at all. The three people sitting in the circular chassis began to pedal the cranks of the bicycle, and the entire crossbow body moved like a European crossbow bow.

It is necessary to explain that European crossbows do not require pedaling strings like those of the Song Dynasty at that time. In the Roman era, they used a push-type crossbow body. That is, two sections of the crossbow body, fixed the crossbow string in advance, and then pushed the slave body connected to the crossbow arm to slide forward, so that the crossbow string can be good. If you are interested, Zhao Fubo's actions in this weapon are that he used bicycle sprockets and tooth belt transmission methods. The operation of the entire crossbow can be completely controlled by the shooter's trigger.

The bicycle sprocket system makes the entire launch process heavy and labor-saving. The two people on both sides are ammunition hands, putting the crossbow arrows in the box in the position so that the entire system can operate continuously. I believe this is easy to think of machine guns, but this thing is fast, but the range is closer. It effectively kills 100 to 150 meters, which is a special adjustment for the rate of fire. However, its range is indeed something that can form a rain of arrows. According to the test, it can shoot 30 times per minute. I believe everyone has already thought of the possible density.

This may cause people who are unaware of the inside story to worry about how powerful such a weapon would be. For Europeans and Arabs, such weapons are powerful enough, but for the Yulin Army of the Song Dynasty, this weapon was eliminated just after the shooting meter was made. Because a weapon of Martin's radiometer in Huaxia Island, the firing rate at the same range can be terrifying.

The reason for using a continuous crossbow bow instead of a crossbow is that this will allow the trigger fuse technology to remain mysterious to Europeans. If you don’t know how to trigger fuses, you have to explore a lot if you want to create a real cannon. The projectile ignition and launching was something that happened when the cannon first appeared. It was then lost. The trigger fuse was a technology that only appeared hundreds of years later.

Although everyone has seen the situation of the Yulin Army's crossbows and bombings, no one can understand what the fuse looks like. As for the future, it would be strange if scholars and craftsmen can be without them.

When the Holy Roman Emperor Frederick II and his son looked at the continuous shooting weapon and kept shooting out the arrows, they were shocked when they listened to Zhao Fubo's "30 shots per minute". Because this thing is a weapon for killing people, it doesn't look very small, even if they are pretending to be a big country, they can run around. If there are not many heads at the city and 20 walls are arranged on each side, then 600 arrows will fly down from the city every minute, which can almost eliminate the defenders' archers.

This is not surprising. In front of the shooter, there is an iron ring with several concentric rings. There is no need to ask about it, which is the sight. With this thing, the shooting of the crossbow arrows has become more accurate. However, the range is really closer. Even if it is on the tall city wall, its effective killing is only 100-150 meters, which is far lower than the maximum killing distance of 250 meters when the pulley bow is shot. But the advantage is that this thing is dense enough. If you dare to concentrate and charge under the city, facing this kind of thing, you will almost die!

"We need to build a few small fortresses outside the urn, so that they need to form mutual covers, and they can also directly protect the urn. The most important thing is that their passage will be located underground. In other words, the other party wants to surround them to cut off those small fortresses, which is just a dream!"

Zhao Fubo's arrangement was actually just an old way to get a mountain carving. Digging ditches underground and covering logs and soil, but it became an underground passage. However, during construction, the entire ground must be covered with a camouflage net and leaves. Even if there are spies from the Pope in the city, there is nothing to see. The slaves who are all from Corsica and are sent back to the island after construction, which can keep these passages and fortresses in a relatively confidential state.

Now you can imagine that when the enemy outside the city attacks the city, facing small fortresses like artillery towers and the rain of arrows shot from the city, the difficulty can be imagined. Of course, in addition, the city walls are also equipped with a shooting base of "reincarnation cannons". This kind of thing will provide firepower and damage of 300 to 500 meters. After entering 200 reals, it will be in the attack range of bows, crossbows, "grenade launchers" known as "conscience cannons" and "shocking thunder". I believe that when you reach the 100-meter range under the city, death will be shrouded in the entire city like dark clouds.
