My physics masters couldn't possibly be grand mages.

The magic class was much more interesting than Char had imagined—at least more interesting than the classes Einstein had taken.

To be honest, Einstein was hardly a good teacher, especially when explaining certain problems. He would subconsciously omit some steps and then inexplicably arrive at a correct answer.

It's as if it's assumed that Char Aznable knew about this process.

Today we'll actually only have this one lesson, because it takes a lot of time to build, stabilize, and master a magical construct.

Apart from Char and Victor, practically no one in the class succeeded.

So basically, we just tell them to go back and try it themselves.

Einstein and Char took advantage of this free time to attend Potions and Alchemy classes respectively in the afternoon.

These two classes are elective courses.

According to the teacher in class, both alchemy and potions are vast systems comparable to magic, and even much more difficult. Without specialization, one cannot achieve anything significant.

The advantage is that both of these are production units in the magical world, so once you start learning, you won't lack money at all, and you can even earn points more easily than the average person.

Many secular magicians choose to practice one of the systems, but often, it is precisely because they practice other systems that their progress in magic is limited.

To be honest, Xia remembered a book he had read before called "If you can't lead a team, you'll just work yourself to death".

If these secular magicians had united and pooled their resources to train alchemists or potion makers, and then had those alchemists in turn benefit the others who studied magic, the outcome would certainly not have been like this.

Trying to do everything yourself will only result in accomplishing nothing.

Char didn't intend to do that, which is why he chose to bring Einstein into this world.

Einstein was the first, but he won't be the last.

What one person can't figure out, a group of people can figure out together.

What one era cannot accomplish, let people from all eras work together to do.

When human wisdom converges into a mighty river, it will sweep away all obstacles that block its path and flow into the vast universe.

"Click~"

Xia Ya pushed open the door and sat down wearily on the sofa.

The sun was gradually setting in the west, and the afterglow shone on the buildings throughout the valley, giving them a golden glow.

Einstein took out his notebook.

What do you want to eat tonight?

"Eat something good," Xia said, feeling a bit tired and having a strong appetite because he had used a lot of magic.

"The roasted lamb chops we had at the banquet before were pretty good."

Einstein tore a piece of paper from his notebook and wrote down "roasted lamb chops" and "some drinks" on it.

He walked slowly to the fireplace and raised his hand.

"call-"

Flames erupted from his palms, igniting the pile of firewood.

Then he threw the paper into the fire.

The paper instantly twisted and turned into dust.

He picked up the fire tongs leaning against the fireplace and knocked on the fireplace three times.

He put down the fire tongs and sat down on the sofa opposite Xia.

"Do you know what your attribute is?" Xia asked curiously.

He had just used the Burning Hand, which was the first time Char had seen Einstein use it.

"No bonuses, but no effects either, so it must be the fifth attribute, 'emptiness'." Einstein murmured softly.

"Emptiness" does not refer to air, but to the state before the other four elements were created, representing "nothingness, connection, and possibility".

Involving spatial manipulation, time, transfer, summoning, souls...

Although it sounds very sophisticated, the problem is that magic involving this attribute usually consumes a lot of resources, carries great risks, and is extremely difficult to learn, making it impossible to form combat power in the early stages.

Later on... magicians who reach that stage usually have their own ways of using these spells.

Most importantly, the void attribute does not provide any bonus to the four most numerous elemental magic types.

"After taking these classes, what do you think magic is?" Einstein asked.

Xia stroked his chin, thought for a moment, and said, "I think this thing is actually more like some kind of 'technology'."

"technology?"

"It's not like a 'mystical gift' in traditional fantasy, but more like a super technology that can be learned, analyzed, and debugged."

He looked up, his eyes gleaming. "Sir, I think I know who our next helper is."

"Engineering," Einstein uttered a term.

Engineering is the natural manager of technology; its essence is the applied discipline that uses the principles of mathematics, physics, and other natural sciences to design objects.

Magic is the same; it is a discipline that applies the principles of mathematics, physics, and other natural sciences to use magical power to achieve miracles.

They actually have many choices.

Further back, there was Leonardo da Vinci of the Renaissance era. This genius, hailed as an all-rounder, possessed engineering concepts and thinking that transcended his time, spanning multiple fields.

The differences in their eras could be overcome by the computer he brought with him for teaching. Einstein could also teach him. As fellow geniuses, his learning progress would certainly be faster than that of ordinary people.

And there's James Watt, the architect of the Industrial Revolution.

Finally, there's... Nikola Tesla, the revolutionary of the electrical age. A pure genius inventor.

If possible, Char would like to bring them all, but he can't travel to all timelines at the same time, and time travel has a certain cooldown.

"Choose Tesla," Einstein said. "He dedicated his life to studying the applications of various forms of energy, and he must have had a great interest in magic."

Xia nodded; he also felt that Tesla was the best choice.

But after a pause, he continued.

"But it seems like he has some... conflict with you?"

Tesla consistently and publicly criticized relativity, calling it "a fallacy disguised as mathematics."

Until the late 19th century, physics was a fairly intuitive science. From the perspective of everyday experience and common sense, the results obtained by physicists were understandable.

However, with the emergence of new trends in physics such as relativity and quantum mechanics, the predictions of physical theories seem to contradict common sense at first glance.

The older one gets, the more stubborn one becomes, and Tesla clearly could not accept that the equation's result defied common sense.

"He was one of the most stubborn and intelligent people I've ever met," Einstein said. "He didn't accept relativity, but that doesn't diminish my respect for his genius."

He paused, then continued, "Can your abilities take me there?"

Xia thought for a moment, then nodded. "It should be possible."

He can take anyone within his sight on a time-travel trip.

The problem is that the people taken away cannot have a significant impact on history, while these scientists are all people who can change the world.

Therefore, he can only choose a point in time when they no longer produce anything.

This means he can only bring one at a time.

"Take me with you, he's not an easy person to get along with."

Which time point do you think would be more suitable?

"He died in 1943," Einstein said, stroking his chin. "But that day certainly couldn't be chosen; it had to be when he still had some energy."

Char raised his hand and took out the computer from his storage space to start searching.

"His last formal, granted U.S. patent was in 1928, when he was 72 years old."

Although he continued to claim the completion of a "Dynamic Theory of Gravity" between 1934 and 1937, and proposed ideas such as the "death ray" in his letters, he was no longer able to produce any tangible results through patent applications or public publications as he had in his youth.

"Then at the end of 1937," Einstein said without hesitation.

Char slowly stood up, raised his hand, and snapped his fingers lightly.

"Clatter~"
