I haven't seen fireworks.

That's right, Shengu Jingyun wants to make gunpowder.

In fact, TNT is better and the technical content is not high, but Kamiya Keiyun doesn't know it. He only remembers mononitrate, disulfide, and charcoal.

I don't know the specific ratio, but it's not a big problem. He is still in school, and the knowledge has not been returned to the teacher. Especially after practicing the "Quiet White Lotus Sutra", his memory is getting better and better. Many forgotten things in previous lives, I can recall it now.

So, just list the chemical formula and calculate it.

黑火药爆炸方程式为2KNO3+S+3C→K2S+N2+3CO2

钾的原子质量为19，氮为14，氧为8，硝石加起来就是（19+14+8*3）*2=114

硫为16，碳为12，所以硫的质量为15，碳为12*3=36.

The final ratio is 114:16:36

That is 7.125:1:2.25.

Shocked, the gunpowder formula passed down is wrong. It should be 7 nitrates, 1 sulfur and 2 charcoal?

No, in fact, the recipe handed down is not a problem, but the unit is different.

The proverb was formed during the Anti-Japanese War. The scales used at that time were 16 taels. Use this scale to take 1 catty of saltpeter, 2 taels of sulfur, and 3 taels of charcoal.

If there are modern time travelers who don't understand this cause and effect and only listen to proverbs, then the ratio of 123 will definitely not make gunpowder.

Making gunpowder is a dangerous job, and Kamiya Jingyun definitely can't do it by himself. It would be unjust if he was killed by the explosion, and Kamiya masonry would have to be done.

All the ingredients of gunpowder are in the earth classification, which is also normal.

"I shouldn't be called Shengu Shigong. Is it too late to change my name to Shengu Nobel?" Shengu Shigong asked a little aggrieved.

Shen Gu Jingyun ignored him, first ate the root ginseng and returned to Lan, and when he was almost back, he created another clone.

It is not safe to study paraquat, so we still have to separate ourselves.

Familiar with the family, let him choose his own name and image.

"Although paraquat is poisonous, there is no separation between medicine and poison, and its harm to weeds is not fake. If it is promoted, the benefits should outweigh the harm. So I am not a sinner who studies poison, but a good remedy for the world. Saint!" The new avatar said: "There just happens to be a character who can cure diseases and kill people, which is more in line with my identity, and I will be called Shengu Bianque!"

After saying that, Kamiya Bianque transformed into a doctor wearing a green robe and a square scarf.

Shengu Jingyun nodded, although the level of this avatar is still a thousand miles away from Bian Que, but Bian Que can be targeted!

Watching the two avatars enter the research room, Shen Gu Jingyun came to the farthest room and sorted out his memory.

He had to find a better way to use the technique of one qi transforming three cleansing.

"I have three clones now, Shen Gu Shi Gong, Shen Gu Yun Xiao, and Shen Gu Bian Que."

Among them, the stone worker is responsible for the earth escape, and there will be things like blasting in the follow-up, which belong to the top-ranked legal fighters.

Yunxiao is responsible for wind escape. He moves quickly and has control. You can refer to Feng Nu to design a wind escape and revive the monsoon. This is an auxiliary.

Bian Que is responsible for medical ninjutsu and poison spells. He is a team-oriented mid laner. He still lacks an ADC and a jungler..."

Kamiya Keiun knew that chakra also had electric properties, didn't Hatake Sakumo do the same?

I can even develop the wind attribute that I don’t have. Electricity should not be a problem. Electricity can develop skills such as electromagnetic guns. Ninjas are fast and can avoid bows and arrows, but can they avoid electromagnetic guns that are several times the speed of sound? ?

"The amount of chakra can't stand it, bear with it!" Jingyun Shengu shook his head, maintaining two avatars at the same time has exceeded his upper limit of chakra, and it is still done by eating ginseng.

He always feels that the medicine is only three parts poisonous. Ginseng can be used, but it cannot be used every day. That is to say, during this period of time, Ken Shimura is under pressure, so he is doing this.

And if there are more clones, there will be less chakra that can be used for Qi training, which will definitely affect the progress of Qi training.

Kamiya Keiyun still knows how to measure, and Qi training is the foundation. If he learns more about Chakra in the future and can use Chakra to extend his life, it will not be about studying whatever he wants to study.

It's enough to master one or two things about chakra attributes. Now to focus on this is to ignore the basics and not distinguish the priorities.

Calm down and enter a meditative state.

Kamiya Keiyun's consciousness appeared in front of Bailian again.

Looking at the empty, dark world around him, he thought of a skill.

Memory palace.

The memory palace is a way to build a memory palace and archive all memories in different categories from front to back.

This method does not come from Xianxia, ​​or fantasy novels, but from reality.

During the Wanli period of the Ming Dynasty, an Italian missionary named Matteo Ricci came to China to carry out Catholic activities in China. The term "God" and the title "God" were started by him.

But in addition to being a missionary, he was also a mathematician, historian, geographer, and linguist.

Matteo Ricci translated Euclid's "Elements of Geometry" (the first six volumes) together with Xu Guangqi and others, and together with Xu Guangqi and Li Zhizao translated "Tongwen Suanzhi", "Measurement Methodology", "Won Rong Comparison" ", these are quite well-known mathematical works.

He also made a map himself, which is the "Kunyu Wanguoquantu" currently in the Nanjing Museum. This map puts Asia in the center of the map for the first time.

He translated "Four Books" into Latin for the first time. He also produced the first Chinese-Western dictionary in history, "Common Questions and Answers", and he even pioneered the phonetic notation of Chinese characters with the Latin alphabet.

This is a real boss who has learned both Chinese and Western cultures, and has had a profound impact on both worlds.

So, why is this big guy so awesome?

Because he himself has a photographic memory.

As for how he did it, Matteo Ricci wrote in his book "Records of the Western Kingdom: Ming Yong Chapter": "Use the image of the original object and the image of the ability to place them in each place sequentially."

Memory, when broken down, includes common daily knowledge, important but not commonly used proper names, real experience, imagination and conjecture, and memories that are both true and false. You can follow their order and importance, as Houses are generally located in various locations.

Depending on the situation of each person, the size of the house will also vary. A small one may be a hut, while a large one may be a real palace.

Later, Yale University professor Shi Jingqian (UK) wrote the book "Matteo Ricci's Memory Palace" based on Matteo Ricci's experience and works, describing in detail how to construct a personal memory palace.

I bought this book when Kamiya Jingyun was in high school, but because the description was too fantasy, I threw it away after reading it once.

But now, with the space for meditation, Kamiya Jingyun found that he seemed to be able to practice the Xianxia version of the Memory Palace.

However, his train of thought is different from that of the memory palace.

Because this book was written in 1984, when computers were not yet popular, this technique is called a memory palace instead of a memory folder.

When it comes to retrieving information, the computer storage method is naturally more advanced and easier to use.

Just think about it and you will know, is it easier to find books according to the brands in the library, or is it easier to search on the computer?

Kamiya Keiyun has no intention of managing his memory. He has a good memory now and will not forget easily. He is also reluctant to put the memory in a folder.

If you seal it up like that, will you still be yourself?

Shengu Jingyun only wants to create folders for Shengu Shigong, Shengu Yunxiao, and Shengu Bianque.

However, the folder is in the form of a card, and printed on the card are the commonly used images of the three of them.

In this way, every time Kamiya Keiyun summons the corresponding character, he only needs to use this card to combine with the body's energy to generate chakra and then release it outside the body.

After the avatar dissipates, the returned spiritual energy Shengu Jingyun will not integrate it into his own spirit, but let it re-form a character card.

As for doing this, will the avatar have its own personality, will it rebel, will it overwhelm the host?

This is naturally impossible, because the basis for the existence of the clone is the ontology, and the spiritual power it constitutes also originates from the ontology.

In short, it is something Kamiya Keiyun made up in his mind. As long as he wants to, he can destroy it in a single thought...

Of course, this is Kamiya Keiyun. If others practice according to Kamiya Keiyun's method, will they develop a second personality, a third personality...

That's not certain.

Jingyun Shengu thought about the three character cards and colored them.

Shengu Bianque has just been born, has nothing, is white, and is a 1-star card.

Although Shengu Yunxiao has mastered Gao Tianchangge, it is not that strong, and it is also a 1 star.

Kamiya Masonry, on the other hand, can perform earth-type ninjutsu well, is easy to use in production, and is not too weak in combat.

It can be rated as two stars.

Still white.

"The name One Qi Transforms into Three Pure Ones is not appropriate..." Kamiya Jingyun looked at the three cards in front of him. This is not the same style as One Qi Transformation into Three Pure Ones. After all, One Qi Transformation into Three Pure Ones means three of himself.

"Great summoning technique? Summoning thousands of troops? Ever-changing scenes?"

Shen Gu Jingyun waved his hand, making a gesture of swaying the card between two fingers.

No, this method should be called: Yuanling Yuchi (chi, just mark it casually, I don’t mean to think that you can’t read it)
