“Uh…”

After a brief moment of stunned silence, Qiaomu smiled and said hello, "I'm meeting again, Sister Paqiusha."

Padyusha: “…”

"It's not yet seven o'clock, can I read a book here for a while, right?" Qiaomu asked.

"Please." After Pachisha said, she ignored Qiaomu and continued to find the book in front of the bookshelf.

After receiving the approval, Qiaomu felt relieved and began to select books he could use.

It is worthy of being the largest library in the Northern Divine Realm. Some pharmacy books that Qiaomu could not find before were available. There are all kinds of books here, and there are even many books that Qiaomu has never heard of, but are of great help to refining medicine.

Really came to the right place!

After carefully selecting a few books, Qiaomu came to the reading area in the museum, found a seat to sit down, and began to study with all his attention.

This study took several hours.

After Qiao Mu felt physically and mentally exhausted, his consciousness was a little blurred, and his learning efficiency was greatly reduced, he stopped.

After standing up and moving his body, Qiaomu noticed that Padyusha was sitting at another table and staring at him.

“Um…”

Qiao Mu realized something, took out the communication crystal and glanced at it, and immediately smiled apologetically, "I'm sorry, I didn't expect it to be nine o'clock in the evening, I forgot to look at the time."

"Are you interested in the production of potions?" Padyusha asked.

"Yes, I'm learning this knowledge." Qiao Mu replied.

"good."

Padyusha nodded, "If it's pharmacy, it's OK to watch it here for a while."

"Then thank you sister Padyusha."

Qiao Mu thanked him, and then wondered: "Just why can you stay in the museum if you learn how to make medicine?"

"I used to be a pharmacy teaching teacher in school."

Padyusha retracted her gaze at Qiaomu and began to fiddle with a bunch of messy objects on the table. "I'm quite pleased that someone is so enthusiastic about pharmacy."

"So that's it." Qiao Mu smiled.

He really likes this thing very much when he learns pharmacy. It’s purely because after learning how to make pharmacy, he has the chance to increase the strength of the reincarnation person several times!

How could this not be crazy?

Unexpectedly, because of this, Padyusha also gained a wave of favor!

This was an unexpected surprise.

The reason why I stayed in the library to read books instead of copying the content of the book back to the dormitory to read it is that Qiao Mu also had the idea of ​​making friends with Padyusha.

Originally, he planned to see if he could talk to Padyusha, but he didn't expect that as soon as he read the book, he forgot about this matter.

at this time.

Seeing the pile of objects that Pachisha had fiddled with, Qiaomu couldn't help but be stunned, "Are you... connecting the circuit?"

"Um?"

Hearing this, Padyusha looked up at him again and frowned, "Do you know this thing?"

"A little understanding of one or two."

Qiao Mu smiled, sat opposite Padyusha, and then guided: "You connect this wire to the positive pole on the left side of the bottom of the light bulb, and then this wire..."

Seeing that Qiaomu seemed to understand very well, Padyusha followed his actions skeptically.

After a while.

The wires that should be connected have been connected, but the simple light bulb still didn't respond.

"Why isn't it light?"

Padyusha narrowed her eyes, "Are you just playing with me... playing with me?"

"I'll take a look."

Qiaomu touched his chin, then pulled the pile of light bulb objects in front of him and carefully checked it.

A few seconds later, he found the problem and smiled, "No wonder, this thing cannot be powered by magic crystals, you have to use a battery."

"Battery?"

Padyusha wondered, “What?”

"Uh, don't you know? Then why are you doing this light bulb..."

Qiao Mu was about to ask how to make the light bulb, but suddenly he found that the light bulb felt something wrong and was a bit too light.

"Wait a little longer."

After thinking about it, Qiao Mu began to dismantle the light bulb in his hand, and then found that the light bulb had only a shell, and there were no electronic components inside.

"You can only be so bright."

Qiao Mu looked at her helplessly, "The most important thing about the technology side is not the appearance, but the inside. It is useless to just imitate the appearance."

"So how can I make it light up?" Padyusha frowned.

"Forget it, I'll make a sample for you."

As Qiaomu said, he began to create various materials needed for the light bulb out of thin air.

Filament, glass lampshade, battery, wires and so on...

After a few minutes.

A small light bulb was assembled.

Qiao Mu pressed the switch, and the light bulb instantly lit up an orange-yellow light, which was extremely conspicuous in the entire slightly dim library.

"It's really bright!"

Padyusha's eyes were full of surprise, and she approached the light bulb and observed carefully, like a curious baby.

“How did it do it?”

Suddenly, Paqiusha raised her head and looked at Qiaomu and asked.

"Uh, let me think about how to explain it to you."

Qiao Mu thought for a while and said: "After turning on the battery, the current will flow from one of the contact points to the other and then to the line and filament. A large number of free electrons in the current of the solid conductor line move from the negative charged area to the positive charged area. The jumping electrons of the vibrating atoms may be temporarily pushed to a higher energy position. When they fall back to their original normal position, the electrons will release additional energy in the form of photons, and then..."

"Speak human words." Padyusha's face turned cold.

"Simply put, it is the same as converting electricity into light, which is to convert magic into light."

Qiao Mu explained: "The transformation of magic into light depends on talismans, formations, etc., and the transformation of electricity into light depends on various physical knowledge."

"What are the specific knowledge!"

Padyusha's face was full of desire: "Teach me!"

"This... I still have to learn knowledge about medicine, I'm afraid I don't..."

"I'll help you with pharmacy."

When Padyusha said this, her face was full of confidence, "No one in the entire Northern Divine Realm knows pharmacy better than me."

"oh?"

Qiao Mu raised his eyebrows and smiled slightly, "Come on, no one in the entire northern divine realm understands physics better than me!"

As he said that, he stretched out his hand, "Then, help each other?"

"I will cooperate with you for now."

Paqiusha thought for a while, reached out to hold Qiao Mu gently, and then asked in confusion: "Talk about it, how did you learn these things? You shouldn't be old, right?"

"This one."

Qiao Mu sighed, "Learn these things, we will start from when the sunset that day, when I was hit on the head by an apple that suddenly fell down…"

Padyusha: “…”

...

It's late at night.

Qiao Mu returned to his dormitory, his face full of fatigue.

It is really not easy to teach a deeply rooted student who has no foundation and is also influenced by the magical concept.

He feels powerless to teach calculus classes to elementary school students.

I really can't teach you!

but.

If you don’t know how to teach, you have to teach!
