On the way back to the school lounge, Harof was discussing with Lin the impact of magic on the curvature of space.

Lin En had been in the field of magic for a long time and had listened to Harov's detailed explanations, so he naturally answered questions fluently. He even brought out the best magic structure proposed by the other party for re-discussion and openly asked about the parts he didn't understand.

As Harof answered the questions one by one, he couldn't help but sigh. Even a three-ring wizard like Lin En had such a deep understanding of the connection between magic and time and space. How could those legendary wizards of the [Arcane Society] know nothing about the optimal magic structure? He really was overthinking it.

Maybe it was just because the questions he asked were too low-level and the other party was too lazy to answer, so he acted so perfunctorily.

Harov thought so, then his expression paused, as if he had heard something, with a helpless expression on his face, but he still spoke.

"I have a friend who is very interested in the glass mirror that can flash and can't wait to have one. Do you still have it in stock?"

Is this friend talking about you?

Lin En looked at Harrov with a strange look. He thought that this legendary wizard, who usually dressed very casually, even unkempt, would not be interested in the glass mirror.

Of course, it may also be due to academic research considerations, or for relatives or children.

Without any hesitation, Lin En handed over the large round mirror that he had removed from the torsion balance device.

"It's twenty gold coins, right? I'll ask Korol to deliver it tomorrow." Harov took the round mirror, said something casually, and then handed it to his side.

Under Lin En's gaze, the round mirror disappeared silently.

Could it be that Harov has something like a storage tool? But why have I never heard of this thing?

Lin En thought about it in surprise, but he didn't ask any questions rashly. After saying goodbye to Harov, he went straight back to the lounge of the school.

He couldn't wait to verify his guess!

After perfecting the law of universal gravitation with the help of the parliament's mobilization capabilities, Lin En had a vague feeling that he did not need more computing power to perform some force field magic.

This is not an unfounded guess, because a wizard's spellcasting can be likened to running a program or solving a very complex equation.

When there are unknown numbers, we can only find the answer by substituting different values ​​over and over again and using the process of elimination.

Now it is equivalent to turning two of the unknowns into definite values. The first is the gravitational constant of the universe, and the second is the space-time curvature of the earth's surface. In this way, the computing power required to release force field magic is reduced by several times.

This is also the reason why Harof and others said that the law of universal gravitation will become the founding theory of space magic.

So during the two days of waiting for the award ceremony, Lin En closed the door to visitors and concentrated on studying the spell model of force field magic.

All other matters were left to Philip and others, and they were asked to purchase a suitable property in Greenridge as the future residence of the Iyeta School.

After all, it's not a good idea to stay in the rest room of the magic seminar every time I come. Although it's quite spacious here, it's not very convenient because there are so many people and too many eyes.

In the six months since arriving in the wizard's land, relying solely on the income brought by the airship and the looting of the manor in Ladakh, he has accumulated nearly five thousand magic gold coins, which is enough to buy a nice manor anywhere outside the prosperous area of ​​Greenriel.

"Magic Missile!"

The next evening, in the training ground, the girl shouted softly, and dozens of flashing magic missiles appeared in the void.

Alok, Pierce and others beside him were not to be outdone. They used the most powerful magic they knew. Several fireballs and ice blades intertwined together, aiming directly at Lin En who was not far in front of them.

However, the latter did not make any movement, and the flames and ice blades were separated by some mysterious force before they touched his body... and passed directly by him and hit the wall behind him.

At first glance, it looked like several apprentices deliberately avoided Lynn and acted as the shooters for the human body outline.

However, Alok and Pierce knew that with a distance of only ten meters and facing a non-moving target, there was no way they would miss!

"Huh~" Lin En did not relax his vigilance just because he easily defended against the attacks of several people. He was even more keenly aware that the magic missile released by Johnny was flying slower than he imagined, and it exploded directly after touching the deflection force field.

There seemed to be nothing inside, but Lin En could sense that the hydrogen content in the air around him was rapidly increasing.

At the same time, Johnny stretched out his left hand and crossed his right hand over his left wrist. That was the starting posture of Touch of Fire!

The weak flame expanded rapidly within a second, and the hot fire stream instantly ignited the hydrogen around Lin En!

Immediately afterwards, a violent explosion sounded in the practice room, and thick smoke mixed with extremely burning flames rushed to the surroundings. Both Alok and Pierce showed horror on their faces. This was almost as destructive as a third-ring magic!

It was the first time they knew that Johnny was so powerful! "Could it be that Professor Lin En was... seriously injured?" Alok stared at the smoke and said uncertainly when he saw no movement for a long time.

How is that possible? Johnny rolled his eyes at Alok, panting lightly, and stopped chasing. Such precise magic coordination consumes a lot of computing power. Even for Johnny, who has become a formal wizard, it is not an easy task.

Amid the billowing smoke, Lin En's powerful voice came out.

"Hydrogen explosion? Interesting... Johnny, you have learned both elements and mathematics very well, but you didn't grasp the ratio of hydrogen to oxygen well. The correct ratio should be 2:1."

After the smoke and dust cleared, Alok and the others discovered that Lin En was still standing there unharmed, not even the corner of his clothes was lifted at all, which made Alok's scalp tingle.

Even an attack close to the third ring of magic couldn't make Lin En move at all, how could he fight? Although it was just an exercise, Alok and Pierce had already felt like giving in, but only Johnny was still full of fighting spirit, she had always wanted to measure the gap between herself and the professor.

"Now it's my turn. Are you ready?" Lin En said with a smile.

Elrod and Pierce swallowed hard, and Johnny was also facing a formidable enemy.

Under the gazes of the three people, Lin En stretched out his hand, and his index and middle fingers trembled slightly, as if he was plucking the strings of a guitar...
