Chapter 462 Bald Again
"Got it!" Su Ying finally remembered what it was, a watertight compartment!
"What?" Lu Zhaoshi and Fu Zhong stared at Su Ying.
"First, build two layers on the bottom of the boat. The outermost layer is for water seepage, and there is another layer inside to block it." Su Ying said.
"Hey! This is a good idea!" Fu Zhong slapped his thigh.
"In addition, the inner bilge is divided into several tanks. The water leakage is only at a certain point. After the separation, we only need to drain the water from the leaking tank, which will not affect the normal use of the ship.
Furthermore, the bulkheads also serve to reinforce the hull. With this technology, even larger ships can be built!" Su Ying continued.
Lu Zhaoshi and Fu Zhong were so shocked that they didn't speak for a long time. How come they didn't think of such a simple truth?
Look at Master Su. He claims he doesn’t know how to build a ship, but this watertight bulkhead is so clever!
"You still say you don't understand!" Fu Zhong said quietly, "I should have let you go through the blueprints earlier!"
"It's still not too late to add another layer to the bottom of the ship and add more compartments!" Su Ying smiled.
"Your ship is too big. In addition to the compartments, the bottom of the inner cabin needs to be made of thickened wooden boards with holes drilled through the middle of each board.
Choose old bamboo strips with good toughness, soak them in tung oil, connect the wooden boards in series, fix them on both sides, and fill the gap in the middle with putty.
The deck is also reinforced in this way, making the hull less likely to disintegrate."
"That is to say, we can build large ships with a capacity of more than 2,000 stones?" Fu Zhong stood up excitedly and clenched his fists with joy.
The problem that has troubled me for almost a year has been solved!
Technology is a paper tiger, and many breakthroughs often occur in inconspicuous places.
The compartment technology is very simple. It divides the space into small pieces to prevent the spread of water seepage and reduce the scope of water seepage treatment.
It is simple, but no one has thought of it.
"Well! I have another suggestion for you!" Su Ying struck while the iron was hot.
"What?" Fu Zhong asked humbly.
"Build a large warship called a frigate. In addition to the battering ram and sledgehammer, equip it with a catapult and a crossbow.
The catapult can not only throw stones, but also throw incendiary and explosive firearms - caltrops, to hit enemy ships.
The crossbow can fire giant rockets continuously, and can also fire explosive projectiles..." Su Ying became more and more excited as she spoke.
Rackets and rams are used to defend and prevent the enemy from jumping off the ship when the enemy and our ships are close to each other.
Catapults and crossbows are used to attack enemy ships from a distance.
In the era of cold weapons, a warship with such configuration has an extremely high combat value!
Lu Zhaoshi and Fuzhong looked at her silently, horror in their eyes.
What did they hear? Fire caltrops, rockets, explosive projectiles! Unheard of!
"Cough cough!" Su Ying realized that her mouth was limp again and she coughed twice awkwardly.
"What is a fire caltrop? What is a crossbow? How to make explosive projectiles?" Lu Zhaoshi's eyes were bloodshot and he grabbed Su Ying.
"Hehe, I was just talking nonsense! It was just fantasy! If you study it according to this idea, you will definitely succeed!" Su Ying said embarrassedly.
Fire caltrops were created by the Xixia people during the same period as the Song Dynasty. They replaced the clay pots that held gunpowder with iron pots.
It is spherical in shape, with densely packed reverse thorns like thorns, and a small hole on the top, which is filled with gunpowder and fuse.
The center of the interior is a centering chamber, which contains small iron blocks. When ignited and detonated, the iron blocks will shatter the blades and cause great damage.
The protrusions scattered on the ground after the explosion can also block the enemy cavalry's iron hooves.
You can use a trebuchet to throw several stones at the same time, or you can throw them by hand.
"No, you must be hiding something, Master Su, that's not nice of you!" Lu Zhaoshi knew that Su Ying was hiding something when he saw her expression.
"Haha, you can ask an alchemist to make an explosive drug and put it into an iron ball that looks like a caltrop, and that will be the fire caltrop.
If you want a more powerful one, you can add pieces of broken iron to it, so that when it explodes, it will fly around and hit people, making it sharper than a sword.
The spikes on the shell of the fire caltrop can also injure horse hooves and stop cavalry!" Su Ying had to reveal a little.
"Since you know about explosives, why do you want us to find an alchemist?" Lu Zhaoshi knew that Su Ying had not finished vomiting.
"Alchemists are very experienced, and ordinary people can easily be killed or injured by the explosion when making it!" Su Ying said helplessly.
"Ingredients!" Lu Zhaoshi stretched out his hand.
"One saltpeter, two yellows, three charcoal!" Su Ying gave up struggling.
"Black powder is made by mixing the hoarfrost on old walls, sulfur, and charcoal powder in a ratio of 1:2:3.
Not only can you craft Fire Caltrops, but you can also craft explosive projectiles and fire them with a crossbow!
It can even be made bigger and made into a cannonball, fired from a cannon, and with a bang, it can hit enemy troops and ships hundreds of feet away!
Make it into a small projectile, fire it from a musket, pull the trigger, and you can easily kill an enemy forty or fifty feet away, much easier than shooting an arrow with a bow..."
Blah blah, he talked about a lot of hot weapons derived from gunpowder.
Lu Zhaoshi and Fu Zhong listened with fascination and enthusiasm.
Looking at the swords, bows and crossbows of the defenders in the distance, they suddenly seemed like children's toys.
"There are such wonderful things in the world!" Lu Zhaoshi's eyes lit up.
The Five Prefectures Governor holds the military power of Lingnan Road. If this thing can be developed, then our Tang Dynasty will be...
"This is just an idea. If you continue your research in this direction, you will succeed soon!" Su Ying didn't want to be left here. She wanted to travel and enjoy the scenery.
Although a lot was said and the gunpowder ratio was given, everything else was very general.
Some only know the general idea, while others keep something in reserve.
"Aying, do you think you can..." Lu Zhaoshi looked at Su Ying and laughed.
“Lord Lu, I have told you everything I know. This is just basic data and ideas.
If you are interested, find someone to develop it yourself! If it succeeds, it will be a great achievement! "
Su Ying said, "Friendly reminder, never eat the pills made by the alchemist. They are poisonous and can cause death if taken for a long time!"
"Ah?" Lu Zhaoshi and Fu Zhong were shocked.
"Don't alchemists make elixirs of immortality? Many cultivators take them, and I haven't seen anyone die from them!"
"My Lords, those medicines contain heavy metals like mercury, as well as arsenic, which is arsenic trioxide.
Although the pill is poisonous, the dosage is small and it will not kill people in one go.
Excessive consumption can damage the liver, spleen, and stomach, causing imbalances in the body's heat and cold, hair loss, irritability, and ultimately death."
Su Ying recalled that the ancients were obsessed with refining elixirs and pursuing immortality.
Lu Zhaoshi and Fu Zhong looked at each other, not quite believing it. Refining elixirs has been done since ancient times, and no one has ever heard of them being poisonous.
"Look, you all don't believe it! If the alchemist keeps on fooling around, I'm afraid you'll all be obsessed with it too! That's my fault!"
Well, it's easy to verify this. If the elixir makes people immortal after eating it, then you can feed it to chickens and rabbits. Chickens and rabbits are small, so you can quickly verify its authenticity."
Su Ying emphasized this matter specifically because she was afraid that the emperor in Chang'an would eat it by mistake.
In history, this heroic and divine Khan was deceived by the so-called Indian master brought back by Wang Xuance, a fierce man who destroyed an entire country alone.
Taking the elixir of immortality caused his body to deteriorate rapidly, his temper became bad and he became irritable, and he died at the age of fifty-three.
Those alchemists were accustomed to playing tricks and using sweet words, and the ancients' yearning for immortality made it easy for them to be deceived.
Su Ying didn't want the alchemist to take advantage of the gunpowder and deceive Tian Khan.
I also hope to warn Tian Khan so that he won’t be fooled by that master in the future.
