The rubber band gun is a kind of classic toy, mostly made of wood or metal materials for the gun body, through a simple design, cleverly using the elastic potential energy of the rubber band itself as a driving force, the rubber band itself as a bullet to fire.

The rubber band gun, as the name suggests, is a toy gun with the rubber band that Xingzhe was familiar with in junior high school as the main power. Unlike a slingshot, the rubber band in a rubber band gun not only powers the gun body, but is also fired as a bullet for the gun.

The flexibility of the band, as well as the limited degree of elasticity, just the right amount to control the "power" of the bullet of the band. This also makes the rubber band gun one of the toys that parents are more at ease than ordinary slingshots and imitation guns that have repeatedly caused tragedies.

The rubber band gun is quite "popular" at home and abroad, especially for the Chinese born in the 70s and 80s of the last century, the rubber band gun is one of the most classic toys in childhood.

Compared with other toys, the rubber band gun has the advantages of strong hands-on, safety, and easy assembly, and more than seventy percent of boys born in that generation have made or used the rubber band gun. After entering the 21st century, the rubber band gun has become not only a kind of children's toy, but also has become a popular collector and model enthusiast because of the memory of the era and the production skills with great potential for improvement.

Traditional rubber band guns are mostly handmade, and most of them are relatively plain in appearance. With the growing demand for the collection and gift of rubber band guns, some manufacturers specializing in the production of rubber band guns have emerged, such as foreign MAGNUM and domestic "Maiji".

Compared with other toy guns, the rubber band gun is safer, which can not only meet the child's playful nature, but also prevent the tragedy, but it is still recommended that consumers must pay attention to the safety of the product in the process of purchasing a toy gun, and avoid buying "three no" products, leaving potential safety hazards

Xingzhe and his classmates have played with or at least touched the toys of rubber band guns when they were children, and there are more self-made ones in the early days, such as simple rubber band guns bent with iron wire or made of chopsticks or wood, and there are also plastic rubber band guns made in batches by professional toy manufacturers, most of which are relatively cheap, with the progress of the times, the production of rubber band guns is becoming more and more sophisticated, the varieties are more and more abundant, and the functions are becoming more and more advanced. Of course, the relative selling price is gradually getting higher and higher.

The gameplay of the Rubber Band Gun is very simple. Under normal circumstances, the head and gear of the rubber band gun are provided with the position of hooking the rubber band, stretching the rubber band, and the two ends are hooked on the gun head at the front end of the rubber band gun and the gear behind the trigger respectively, and the hook is released at one end of the gear when shooting, and the rubber band will be launched due to its own elastic potential energy.

The wood is very easy to make and can be seen everywhere, just find a carpenter to polish it according to the drawn drawings.

The most important thing about the rubber band gun is the rubber band, and what Xingzhe wants to do now is a killing weapon, not a toy gun, so the rubber band must be very elastic, so that the ammunition shot out will be more destructive.

Coincidentally, Lin Xiao knew a craftsman who had a unique skill that could turn animal skins into elastic bowstrings through special processing methods.

It is said that any bowstring made by this craftsman can be sold for a very high price, and it will be contested by the generals, and everyone wants to buy the bowstring made by him.

With the bowstring made by this craftsman, the range of the bow and arrow can be greatly increased, and the penetration power is far from being comparable to that of ordinary bows and arrows.

However, this craftsman does not often make bowstrings, unless he is a friend or he has nothing to do to practice his craft, which is why his bowstrings can be sold for sky-high prices.

And Lin Xiao's bow and arrow skills are very superb, and the requirements for bows are naturally very high, so he got to know the craftsman, and the craftsman is also willing to make bowstrings for Lin Xiao.

Through Lin Xiao's relationship, he got a lot of powerful bowstrings, and with these bowstrings, Xingzhe equipped each of the more than 30 soldiers of the pro-guard team with a rubber band gun S.

The head of the cold iron used for ammunition, Xingzhe deliberately tried it with his own hands, pulled the rubber band of the rubber band gun to the end, and the ammunition shot out was enough to penetrate the armor, but it was still a little difficult to penetrate the shield, but it could already be nailed to the shield like a nail.

In addition, Xingzhe specially exerted his soft grinding and hard foaming skills, and insisted on asking for more than thirty muskets from Qin Yu's hands, and one from the personal guards.

Xingzhe plans to train the rest of the pro-guards as special forces, so the requirements for them are very strict, and the training intensity given to them is not comparable to that of ordinary soldiers.

However, none of these pro-guards gave up, although they all gritted their teeth, they all persevered, and none of them were deserters.

Xingzhe was very happy to have such subordinates, so he took out all the training methods he had learned about special forces and spies, just to train the remaining pro-guard team into another Flying Tigers.

This time to go to sea, the most important thing is the warship, the scale of the warship of the Tang Dynasty is still limited, the draft is limited, and the soldiers carried are also limited.

If you want to transport a large number of soldiers to the neon country, it is inevitable to form a huge naval fleet, and in this case, not only is it very easy to be noticed by the opponent, but the most worrying thing is that the front and back are not coordinated, the warships in the back and the warships in front are too far apart, and if there is an emergency battle, it is impossible to agree to come over in a short time and cannot make support.

However, Datang had a treasure, which Qin Yu didn't want to use, but under Xingzhe's repeated requests, Qin Yu still compromised.

This ship is very huge, and it is simply a giant beast that braves the wind and waves on the surface of the sea - a treasure ship.

According to relevant information, the large treasure ship is equipped with nine masts and 12 sails, and its "canopy, sails, anchors, and rudders, which cannot be moved by two or three hundred people."

According to what Lin Xiao said, this treasure ship is the same as the one Zheng He went to the Western Ocean, but this one has more powerful combat capabilities and should be improved.

According to the British scholar Mills's calculations, the treasure ship has a displacement of 3,100 tons and a load of 2,500 tons. According to the calculations of Chinese scholar Tang Zhiba, the data are contained in the seventh chapter of his book "History of Chinese Ships", the displacement of the treasure ship should reach 5000~10000 tons, and according to the cooperation of Jimei Aviation College, Dalian Maritime College and Wuhan Water Transport Engineering College in 1985, according to the principle of shipbuilding and the Chinese style of wooden sailing ship construction after the restoration of the treasure ship, the largest treasure ship is calculated to have a full load displacement of about 22,848 tons, a square coefficient of 0.43, and a load of 9,824 tons, which should be the most authoritative and true data.

The great wisdom of the Chinese ancestors is impressive, compared to the Western wooden sailing ships have never exceeded 10,000 tons, the 13th ~ 17th century European Caravel sailing ships have a displacement of 2,000 ~ 4,000 tons, 3~4 masts, and the large wooden sailing ships in the West are easy to sink first, seriously affecting the navigation performance, and even leading to the disintegration of the ship in the storm. The emergence of the treasure ship shows that China's shipbuilding technology has solved the problem of hull strength and timber tenon, and such a huge wooden ship can still withstand the stormy waves of the Indian Ocean.
