The two of them looked at this high-end tea canister, it turned out to be from the village chief, Qin Shuai said that it was taken from him, Qin Chuan was quite surprised.

Because of this grade of tea cans, how can they appear in a small mountain village, Qin Tuan rarely has this grade of tea cans, it can be seen that the village chief must have made a lot of money or someone gave it away, but how can a small village receive such an honor? There should be something unusual.

Qin Chuan smelled the fragrance of tea, praised it, and said: "I didn't expect the village chief of a small mountain village to have such high-end goods, and Qin Shuai, do you know that it is a special Longjing, how many levels of this tea are there?" ”

Qin Shuai said: "Longjing is generally divided into six grades, and the first-class Longjing tea is characterized by flatness and sharpness, and the color is emerald green and moist, and it smells of a special aroma. The second-grade Longjing tea is characterized by flat and bud edges, which looks clean, and the color is green with emerald, while the third-grade Longjing tea has a clean and green appearance and a pure aroma. The appearance of the fourth-grade Longjing tea is clean and green, and the aroma is pure...... The appearance of the fifth-grade Longjing tea is green and yellowish, and the taste is not mellow. The quality characteristics of sixth-grade Longjing tea are that it is under-flattened and broad, the aroma is relatively coarse, and the taste is very coarse. ”

Qin Chuan smiled: "You are right, it seems that you like to drink tea like my uncle...... However, my uncle's temper is not like that of a tea drinker, and you are very elegant. ”

Qin Shuai smiled heartily and gestured to invite him.

The two of them went to the table to make tea, and while drinking, they looked at a book, which was a book about armor, and Qin Chuan asked Qin Shuai for advice.

Qin Shuai was actually very interested in this kind of ship armor. Legend has it that when neighboring countries loaded metal armor plates on cruisers, naval ships began to be quickly armed into steel behemoths covered in metal armor plates. In one war, the North and the South exchanged ironclad warships for the first time, and the two sides fired hundreds of shells, but they failed to hurt each other until the shells were exhausted. This battle fully illustrates the impact of armor protection on ship design and the form of naval warfare.

Since then, the ship's artillery and armor have developed rapidly, and the offensive and defensive advantages have been reversed several times. When case-hardened armor appeared, just six inches of case-hardened armor was enough to block the bombardment of twelve-inch guns.

But the myth of hardened armor was soon shattered, and the appearance of cap-piercing shells leveled the scales against armor shells.

Until the battleship that relied on giant artillery and heavy armor to win reached its peak, a battleship was equipped with a main armor belt up to 410 mm thick, which could withstand the bombardment of its own 4 giant guns at a certain distance, and the armor protection on the front of the main turret was even 650 mm thick, which was indestructible.

The two of them were very interested in these combat equipment. While drinking tea, he talked about his future ideals, but Qin Chuan felt more and more tired, and he felt strange, because he was very energetic after drinking the coffee-colored drink before, but it was not coffee, he knew it, but logically speaking, drinking tea would become more and more excited, but he was getting more and more sleepy, but Qin Shuai felt that his current state was the state he should be. He had been tossing and turning all night, and he hadn't slept much, and now he was sleepy and tired, but it was normal, so these were two corresponding substances.

Qin Chuan told him that there was still some leftover from the coffee-colored drink he had drunk before on the table, and Qin Shuai arranged for him to rest and go over there to study by himself.

Through his unique observation, Qin Shuai found that this coffee-colored drink is actually a special substance, which is made of a plant material, its taste is very delicious, but it is also drunk by people, some people may not be able to adapt to this taste, Qin Chuan may just like this special taste, so he drank more.

The other soldiers didn't drink so much, so it didn't affect their sleep, but he played a coffee refreshment effect, and the tea just now was a normal tea leaf, so this energy was relative, Qin Shuai actually measured a special element through research. The element is very similar to an alien armor powder.

He couldn't help but think of an alien armored vehicle.

In the First World War, the armored vehicles of the neighbors were pushed into the battlefield, known as the machine gun destroyers, relying on the steel armor plates on the vehicles to break through the battle lines of the Union army with dense machine gun fire. The system of armored vehicles of later periods set the basis for modern army armored vehicles. Tanks with strong offensive and defensive capabilities, self-propelled guns with considerable mobility and survivability on the basis of strong support firepower, etc,...... The armored force system composed of infantry fighting vehicles, which provide protection for offensive infantry, has greatly improved the combat effectiveness of modern and modern armies.

What everyone is looking forward to now is some special equipment, which is used in the current armor of the alliance army, that is, the structure composed of solid metal or non-metal materials on ordinary military equipment and facilities, which can defend against physical attacks of a certain energy and reduce the damage of protected targets. It can be divided into two types: passive armor and active armor.

In terms of passive armor, Qin Shuai has studied less, and he pays more attention to active armor. Active armor consists of automatic detection, discrimination, and attack systems, which play a protective role by intercepting incoming warheads.

Now he can make active armor with some of the materials he has obtained here, and not only does he have to make these, but he also has to make his flying machine, which can be used in the air, and then operate it with his robot.

He returned to the table, the water was still hot, seeing that the tea was still very fragrant, he tasted the tea again, the village chief gave him this is actually a special Longjing tea, this kind of tea is not in this mountain, it is produced in a very far place, and it is just made tea and sent over, so it is worth a lot of money, the locals are high-end gifts to famous families, but there are many in the village chief's house.

When he left that day, the boy took it from the table by the way, and he could catch several such similar items, and the village chief did not go out of his way to select them for him, but took them so high-end and exquisite.

Therefore, this village chief's family must have unknown wealth, and they know a lot of famous families, otherwise this thing will not be in their hands, because Qin Chuan said that this kind of high-end goods are rare even on the side of the head of Qin, and the head of Qin used to spend a lot of money to ask someone to help him buy this kind of thing, so this matter is not so simple. Qin Shuai remembered that he had studied tea. But there are not as many good tea leaves as the village chief in his hands.
