Although Yu felt that his health was not serious, at the insistence of his mother-in-law and two younger sisters, he was asked to take leave and stay at home to recuperate.

The two deans came to visit him early the next morning, and the matter of asking for leave was decided in a few words between his mother-in-law and the two deans. According to his current situation, the practice of the magic system is basically self-study and practical classes.

It doesn't really matter whether he participates or not. He can already wait for graduation. According to the two deans, it would be no problem to give him a long-term leave of absence after the exchange meeting of the five major colleges is over.

Fortunately, his mother-in-law immediately rejected the proposal for him. There was still one week left before the opening of the exchange meeting of the five major colleges, so the rest time was set for five days. The two deans agreed happily, but they looked obviously worried.

It seems there are still many concerns.

From the two deans, Yu learned about the situation of the last battle. The three black-faced magic tools turned out to be the latest model of demon-hunting weapons. He unknowingly became the test subject of the new type of demon-hunting weapons.

! What was summoned by the superposition of the three black faces turned out to be the clone of the artifact Demon Hunting Crown, and Eragon’s last weird move turned out to be the soul-eating technique of the Demon Hunting Crown!

Fortunately, he was protected by the rune placenta, so he was safe.

The two deans did not explain much, only that all this was the instruction of the Nalan Yi people, and now the entire Nalan family has been expelled from the college.

Yu didn't know why Nalan Yiren and his brother were targeting him so much. In his opinion, it probably had something to do with his status as a "sinner"...

This matter has now come to an end, and his life is normal except that he does not have to go to the academy.

Although it is extremely rare to face ultra-level magic equipment like the Demon Hunting Arms, he is more aware of the limitations of the "Scroll School"! He also understands why the "Scroll School" is synonymous with "mediocre" in the eyes of the world!

He was still capable of fighting in the duel with Nalan Yimin, but the battle with Yihu was already the peak of his current strength. Even if he could continue to improve and be able to draw a seven-star level primary formation, his combat effectiveness would still be at a loss.

It is difficult to achieve a dramatic increase!

Although the number of primary formations is huge, they are all simulations and applications of classic spells. The gap in offensive and defensive capabilities is not outstanding, and the upper limit of combat power is also very clear! It is simply not as good as the infinite growth fusion like "Fire Tornado"

Magic, or a highly adaptable martial skill like "Gang Body"!

What's the point if you just use "superposition", "yuanli micro-management" and other means to purely pursue the improvement of offensive and defensive capabilities? In the face of true power, those means are just icing on the cake, or clever tricks!

Therefore, we still need to develop exclusive moves!

In the final analysis, his "Yuanli Bomb" is the pursuit of maximizing contact with black and white Yuanli! He also has some ideas.

One idea is to combine multiple ancient weapon formations together to form a "power bullet chain" connected end to end. After hitting the target continuously, the power may increase significantly.

The other is to improve the ancient weapon formation diagram and make the elemental bombs rotate like an elemental centrifuge!

However, these two ideas are completely unrealistic!

The former requires fine time control, just like Grandpa He's nursery, which belongs to a composite formation system. The design of the central sub-array has long gone beyond the scope of primary magic engineering!

Not to mention the latter, the elemental centrifuge must be accelerated to 100,000 times to separate the third elemental force. This is even more impossible in the field of primary magic engineering!

After thinking hard, he had no choice but to give up temporarily, logged into the magic network, took on many tasks in one go, and started swiping furiously.

The tasks in the Junior Magic Maker section are now even easier for him. He has completed all the thousands of tasks in just a few hours. His crystal power reserves have increased again and are about to exceed the two thousand mark.

If the primary formation materials in his hand were not used up again, he could continue to use them.

But in contrast, the bounty tasks in the forum were also completely empty. After he took those tasks, the other tasks were also quickly snatched up. Even if he still had the materials, the new ones were added in just a few hours.

There are not many tasks.

He had no choice but to stop. His body was not very tired. The slightly slanting sun lazily climbed into the window. The room looked a little dim. There was still some time before dinner, so he felt a little bored for a while.

At this time, the inheritance library shook slightly, seeming to call him over.

The bead on the top of the study room has disappeared, and the signs of damage in the past are no longer there. The study room seems larger.

When I stepped into consciousness, the study room was filled with heavy fog!

The rows of bookshelves were obscured by the mist, leaving a faint outline that seemed to be stretched far away.

A small group of faint light was near the door of the study room, and a single desk was placed inside, obviously waiting for him.

Yu was very confused and walked to the table and sat down. The tabletop suddenly flashed, and a large piece of paper and a pen appeared.

Yu took a closer look and saw a line of large characters at the header of the page - "Introductory Exam Paper for Elementary Demonology (Difficulty: Seven Stars)".

…Is it possible that the knowledge I learned before is just a preparation for getting started in the field of elementary magic engineering?

…That knowledge is obviously much more profound than the courses in the academy…

Thinking of how complacent he was after chewing up all that knowledge, he couldn't help but feel ashamed! But he immediately became excited - as long as he passed this exam, the true science of magic would be unveiled!

The test paper seemed to be able to detect his mood, and the test questions were revealed one by one.

The first question lit up first, seeming to urge him to answer:

"Briefly describe the principle of the earth magic 'Primary Gravity'. If the human world is a uniform sphere with a radius r, try to compare the effects of the spell on the ground with that at a height of 1 kilometer."

This first question is not easy. It is worthy of the "seven-star difficulty"! Yu's expression is serious and he is becoming more and more cautious!

The principle of the earth magic "Primary Gravity" is actually very simple. It is similar to "Stoneskin" and "Rock Armor". They both use earth magic to simulate the shape of rocks. The difference is that "Gravity" is used on the opponent.

It just uses the weight of the rock form to affect the opponent's actions.

"Elementary Gravity" is quite difficult among elementary magics. It is a magic between four and five stars. However, due to the strength of elementary professionals, the rock form is not solid and the effect is not significant, so it is rarely used in actual combat.

, If Yu hadn't really finished all the previous knowledge, and he had also drawn the "Elementary Gravity Technique", he might not even be able to answer this first question!

...Hmm...This is a mechanical question. According to the law of universal gravitation of Master Fa Shen, gravity is the gravity of the human realm...The question sets the human realm as a uniform sphere for the convenience of calculation...According to the laws of classical mechanics, force is equal to mass times

In terms of acceleration, gravity is mass multiplied by gravitational acceleration... The magic effect at high altitude and on the ground is only different in gravitational acceleration, and gravitational acceleration is inversely proportional to the square of the distance. If other parameters are the same, the magic effect at high altitude will be reduced to two

The ratio of squared distances!
