The "Composite Armor" and "Fence Armor" technologies are not too difficult, at least not as high as "Spell Salt".

To explain it simply, composite armor is the opposite of homogeneous armor.

Homogeneous armor is armor made of a single material, such as steel armor, aluminum alloy armor, etc., and the defense is good, but if you want to greatly improve the defense, you can only continue to increase the thickness of the armor.

Composite armor, on the other hand, is composed of more than two layers of protective materials with different properties. Because the protective materials are different, the physical properties of each are also different. In the process of external attacks trying to penetrate, different physical properties will make a big difference, thus interfering with the direction of the attack.

When a shell hits the composite armor, it looks like it penetrates the first layer of armor vertically, but after touching the second layer of armor, it may cause the angle of penetration of the shell to change due to the difference in the hardness of the second layer of armor, or even get stuck directly between the armor.

Composite armor uses this technology to greatly improve the armor defense without increasing the thickness of the armor.

Fence armor is even simpler, in a word, that is, defense in advance, detonation.

The fence armor that is generally mounted on the tank is like a wire bird cage covering the shell of the tank. This kind of existence naturally can't defend against any powerful attacks - with a small hammer, the metal fence can be smashed flat. However, it allows some powerful attacks to burst in force in advance, so as to avoid being destroyed.

For example, if a rocket hits a tank, it needs to pass through the fence before it can hit the tank's actual armor. Although the fence armor is extremely weak, it is also real, and even a small hammer can be smashed flat, and it must be smashed before it can be passed.

And will the rockets carry a hammer with them, ready to smash the fence armor?

Obviously not, so if you want to pass through the fence armor, you can only detonate the explosive power of the projectile body in advance.

In this way, the fence armor may be blown apart, but at least half of the power of the projectile will be wasted out of thin air, and the rest can be applied to the real armor behind the fence armor that has applied various technologies such as "reaction" and "compound", so that it is basically impossible to penetrate.

So, how do you achieve these with spells?

According to Richard's conjecture, it would not be difficult to achieve.

Composite armor can be made using different non-Newtonian fluids, and then the number of layers of composite armor can be flexibly determined according to different combat situations.

Fence armor can be simulated with wind spells, creating an air shield that blocks in front of the reaction shield.

However, just because it's not difficult doesn't mean it can be done easily. Whether it's trying to make a new, qualified non-Newtonian fluid, or testing the best defense data for air, it takes a lot of simulations – without a lot of time, no results.

This needs to be studied with a deep heart.

In addition, the sixth is the improvement and upgrading of the Eden energy system, which is also the last research that Richard wants to conduct so far.

In the Garden of Eden, the lighting system is electric light, oil lamp, and candle in parallel, and the reason for this is because of the lack of electricity. After all, electricity currently relies mainly on lead-acid batteries, which are charged by Pandora with hand-cranked generators.

Therefore, the source of energy is considered mechanical energy, or further, biological energy (the energy in Pandora's body).

In this way, unless Pandora is designed as a generator in its entirety, there will be no great progress to meet the growing demand in the Garden of Eden.

In Richard's opinion, if he could, he could save some trouble by making a steam engine or an internal combustion engine.

However, both the steam engine and the internal combustion engine rely on fossil fuels – the steam engine burns coal, and the internal combustion engine burns oil. Neither of these resources, which are currently widely used in the world, at least on the East Coast, are hard to find. Unless he was prepared to become a geologist and mine owner himself, spending years mining himself, it would be difficult to get a large supply.

How do we solve this problem?

Or maybe the improvement and upgrade plan of the Eden energy system will be postponed for a while?

Lee senses that this question needs to be thought through.

......

Richard was busy, constantly busy, thinking and doing all kinds of research.

And so, by the time I came out of the Garden of Eden again, it was already a day later.

......

Early in the morning, Richard walked out of the Garden of Eden, out of the makeshift cabin, and onto the deck.

Here, Richard saw Jack, the diminutive sailor he had seen earlier, kneeling on the deck, surrounded by a large group of sailors, while Captain Morgan was standing in front of Jack, swinging his whip so hard that he was beating Jack to pieces.

"Bang Bang!"

Jack screamed and begged for mercy: "Boat...... Spare me, Captain, I was wrong, I really know I was wrong. ”

"Do you know it's wrong?" Captain Morgan snorted coldly, whipping harder, and said as he whipped it, "Since you know it's wrong, why don't you do it well?" I transferred you to the kitchen yesterday to help, and let you cook with the rest of the cooks. The first lunch was so bad that it didn't matter, why did the second one get worse, and everyone who ate it had diarrhea! Are you going to poison everyone and kill everyone?"

"No, I just accidentally didn't cook something, so I ......," Jack explained.

"Tribble, it's all quibbles!" Captain Morgan was very angry, and the whip continued to swing, hitting Jack again and again, "Don't you know how to cook, don't you know how to cook things, don't you know how to taste the food yourself, before serving it? Do you know that you made a dinner and made several sailors on my ship still lie in hammocks! Can you do things for them?

"I ...... "Jack was about to say something, but after only one word, he was whipped to the ground by Captain Morgan, and rolled on the ground in pain.

"Bang Bang!"

Captain Morgan had been whipping for a long time, and when he felt tired, he stopped.

Jack was lying on the deck, his clothes were in tatters, and he was covered with wounds, slowly raised his head, looked at Captain Morgan in fear and said, "Captain, you ......"

"Hmph, I'll give you another chance. Captain Morgan pointed at Jack and said, "Now you get out of the kitchen for me and make breakfast for one." If you can satisfy me, forget your mistakes and work hard in the kitchen in the future. If it still doesn't work, hmph, then you're going to hang on the mast for a day today!"

"This!" said Jack, shaking all over.

Captain Morgan's eyes widened slightly: "What, you're not happy?"

"No, no, I'll go, I'll go. Jack struggled to his feet, wiped the blood from his face, and staggered towards the kitchen.

Numerous sailors, first mates, second officers, third officers, boatswain, and Captain Morgan were waiting on deck.

In a corner of the deck, Richard stood, watching. And next to it, there are other passengers watching the excitement. Some of them are from the lower cabins, and the other part is from the upper cabins, and the clothes are slightly gorgeous, and the complexion is better. They were quietly discussing, laughing out loud from time to time.

"I say, I bet you, that poor dwarf sailor, that will surely suffer. ”

"I don't bet on you, because you don't have to say it at all, and I know it's going to be like this. Look at the way that dwarf sailor looks, could it be the ingredients for cooking?"

"yes, skinny and small, I suspect he won't be able to eat, let alone cook. ”

"Not necessarily. The reason why he is so thin may be the reason when he was a child. So, I may eat when I eat, but if I eat milk, hehe, I don't necessarily will!"

"Hahaha, you guy......"

Laughter rang out, and the captain Morgan in the distance listened to it, frowning slightly, but after seeing that it was a passenger, he didn't react much. He has always been cold to passengers, and although he does not treat passengers as rough as members of the ship, he also does not communicate with them. So, after just a glance, he withdrew his gaze, then turned his head to look in the direction of the kitchen, and waited patiently for Sailor Jack to bring him something.
