After chatting upstairs for so long, the downstairs dining hall had long since ended, Lu Xiaoman carried the scooter out of the gate, put the cat in the basket, she stood on the pedal with both feet, and walked back slowly, silent along the way, not knowing what she was thinking.

After returning to the residence, Lu Xiaoman lit the candlestick on the desk in the study, looked at the candlelight and sighed.

[You still have to have electricity to make it, this only relies on fluorescent stones and candles for lighting, where is it like a civilized society. 】

[You've been thinking about this all the way? The big orange cat jumped on the table and wagged its tail softly and soothingly.

[Yes, there is electricity to have everything. 】

[Yes, if you have an idea, do it, what do you plan to do first? 】

[Worship the ancestor first. 】

Lu Xiaoman walked to the window and opened the window, clasped his hands together, looked up at the night sky, and said something in his mouth.

"Master Faraday, please give me the light of your wisdom."

Ye Zhou has a black line on his head, worshipping Faraday in this world? But after thinking about it, I was convinced, if I want electricity, I really have to worship this ancestral master, even if it's just for psychological comfort?

Lu Xiaoman worshipped Faraday very religiously, and worshipped all the great powers in the field of electricity and electromagnetism, and then thought about it, and then continued to worship the master of chemistry for another round.

Mathematics, physics and chemistry are not separated, and there is no separation in any world.

Ye Zhou patiently waited for Lu Xiaoman to finish worshipping the master, and when she left the window and returned to the table, he asked her curiously.

[Did so many masters give you any advice?] 】

Lu Xiaoman really nodded, [Start with chemistry first, figure out the proportion of air components such as hydrogen, oxygen, nitrogen, carbon dioxide, and inert gases, separate the aura in the air, and explore the way to artificially prepare the aura. 】

[What?! Artificially prepared Reiki?! Are you serious? The big orange cat was shocked, and its fur exploded.

[The world is made of matter, including invisible gases and light, as long as it is matter, there is a way to prepare it, and Reiki must be prepared artificially. 】

Ye Zhou rolled his eyes, shook the exploded hair, and returned to the calm cute cat appearance of the eight winds.

[Artificially prepared aura, really only you dare to think and dare to say. Ye Zhou's tail swayed back and forth a little violently, revealing a little real emotion, [Then you need a whole set of tools for air composition experiments, but in the mass production stage, what method do you plan to use? 】

[In order to imitate the method of preparing oxygen, the air is first pressurized to a liquid state, and then the pressure is slowly raised, using the different boiling points of various gases to remove other gases, and finally leaving a purer aura. 】

[This is to extract the aura directly from the air, but now the aura of the wind and sound realm has been thinned, and before we know how the aura is generated, what you need is a preparation method out of nothing. 】

[Matter cannot be produced out of thin air, there must be a source, the thinning of aura must be the destruction of the ecological cycle that produces aura, for example, the photosynthesis of plants produces oxygen, and it is nitrogen that promotes photosynthesis, so adding nitrogen fertilizer to plants helps plants grow, and solid nitrogen comes from lightning and the high temperature of volcanic eruptions. Unlike the earth, the air composition cannot be rigid, but every gas must have a source. 】

[The source of the aura may be the gas overflow of the spiritual vein, and the great world with rich spiritual energy can mine the best spirit stones, and the spirit stones come from the mining of the spiritual veins, and when the spiritual energy is no longer rich, the quality of the spirit stones will also decline. 】
