The more Xie Yu flipped through the "Wood Secrets" in his hand, the more he couldn't help but feel the breadth of the wooden machine in his heart, and he also admired the sage who compiled this book... If it weren't for the real saints, how could there be such a clever skill?

Originally, Xie Yu thought that the difference between the two offensive and defensive techniques was only that, compared with his own defense... The attack three type is to make the structure and construction of the wood machine more flexible and changeable, and also pay more attention to the production process of small tenons... Exquisite... In short, the Tapping Wood Machine is about maneuverability, dexterity, lethality and speed of destruction.

But after reading this "Wood Secrets", Xie Yu's thoughts in his heart were completely opposite... The concept and cognition of woodworking in my mind have been subverted.

It's just imaginative, except for the building boats, wooden oxen and flowing horses, rushing cars recorded in the first chapter... These are still within the scope that Xie Yu can barely understand, and at the beginning of the second chapter, Xie Yu can't understand it at all.

The text is still in seal script, but the special nouns explained in detail really make Xie Yu scratch his head.

Such as gunpowder... Described as a mixture of potassium nitrate, sulfur, charcoal powder... This mixture is extremely flammable and burns quite violently. An explosion occurs if the gunpowder burns in a closed container. When gunpowder is burned, it can produce a large amount of gas and heat.

The volume of gunpowder, which was originally a small solid one, suddenly expands and soars to several thousand times, at which point the container explodes. Such is the explosive properties of gunpowder. A wide variety of firearms can be made by using the burning and explosive properties of gunpowder.

This type of firearm is mainly used to fortify or defend cities.

The gunpowder broke out, the sound was like thunder, the heat reached more than half an acre, the people and cowhides were broken and there was no trace, and the armor and iron were all penetrated."

The production method is: two taels of sulfur, two taels of nitrate, and three and a half coins of aristolochia. The right is the end, mix well. Dig a pit and put the medicine in the tank and the ground. Put the cooked fire together, the marble is large, put it inside, and the smoke gradually rises.

Furlong Cannon: The Furlong cannon (the upper one is the sub-gun, the lower one is the female gun) is composed of the mother gun and the child gun. The female body is slender and has a small caliber, and the body is equipped with a front sight and a light door, which can aim and shoot at long-distance targets. There are gun lugs on both sides of the gun body, which can be placed on the bracket and can be tilted to adjust the firing angle. The rear part of the gun is thicker, and there are long holes and grooves to fill the guns. Similar to small firearms, each mother has five to nine mothers, which can be preloaded with ammunition for later use, and can be loaded into the mother guns in turn to fire during combat, thus increasing the firing speed.

Rifled guns, front rifled guns: also known as rifled guns, are to make the projectile play a tight plug role in the chamber and increase the loading speed, with a spiral rifled gun, using a round lead ball projectile. When fired, the long lead shot can be rotated, and the flight is stable after discharge, which improves the shooting accuracy and increases the firing range.

This device weighs about 4.8 kilograms, 4 spiral-shaped riflings, the maximum range is 914 meters, the projectile is long, the head is egg-shaped, the bottom is hollow, the caliber is slightly smaller, it is relatively easy to fill from the muzzle, and the gunpowder gas expands the bottom of the bullet and embeds it in the rifling to rotate when fired.

And in the third and final chapter of the book... It made Xie Yu's scalp tingle.

Because the text recorded in it is not even a seal script, but a dense square and square, green, fat, red and thin stick script!

Even if Xie Yu is familiar with the classics of the past hundred years, knows the seven languages, and is familiar with the witch culture, he can't find even a trace of familiarity from the words here.

...

It can be said that in the entire third chapter, he can only understand a little picture.

Xie Yu was shocked.

It's no wonder that the master of public loss would say that even he can't fully understand the true nature of this "Wood Secret" until now.

It's a lot of tricks... Xie Yu frowned.

Xie Yu wrote in his womb and began to conceive the compilation idea of the fake book "Wood Secrets"...
