Afternoon.

Thrandis Cottage.

In fact, most of the things in the house are there, and I haven't been passive much.

After all, Thrandis was a full-fledged mid-level mage, and he was very powerful.

Until she was officially brought in, the ordinary guards would not dare to touch her things.

So, after a little repair, in just half an hour, the hut was back to its usual order.

The second floor of the cottage.

Thrandis, who had already bathed and changed clothes, wore a soft and warm thick cotton dress at home, sat hunched on a thick leather chair, and held a delicate afternoon dessert specially prepared by Lawson in his hand, and enjoyed it beautifully.

"Ah~~ This is a beautiful life."

Clean, warm, no worries about money, and a good apprentice who takes care of you, it's just flawless.

After a few bites of dessert to fill his empty stomach a little, Thrandis looked at the hard-working apprentice who was drying his dress by the window.

"Rosen, my dearest apprentice, everyone has vices, and so do mentors."

"Mentor: I'm lazy, withdrawn, not good at housework, averse to socializing, and incomprehensible. The only advantage is probably a slight achievement in spells. ”

"Of course, this achievement is not very high, and it will soon be surpassed by my dearest apprentice."

Rosen shrugged his shoulders and said he didn't have that much ability.

"Mentor, my spell-casting ability is only 4 stars, and you are at least 20 stars, which may be a height that I will never reach in my life."

Spellcasting ability is a very difficult thing to practice, even more difficult than increasing mana, and the higher the number of stars, the more difficult it is to improve. In the later stage, not to mention improving one star, a little improvement is a huge progress.

This is not only introduced in the book, but also Rosen's practical experience.

Thrandis grinned.

"My dearest apprentice, don't be discouraged, it's terrifying enough to grow from ignorance to a low-level mage in just two months, and to have a four-star spell casting ability."

After laughing, she became a little more serious.

"You're my only apprentice, probably the last."

"As your mentor, I will naturally teach you all my knowledge, including techniques for training spellcasting abilities."

Rosen's heart fluttered because this was exactly what he was asking for: "Mentor, I will study with all my might." ”

"I have no doubt about that, and I believe that you will do your best in a very short period of time, and even surpass me."

"For example, several extraordinary spells you've created have been eye-opening for me. Especially the flying arts, I can't even understand it. ”

After a pause, she looked at Rosen with sparkling eyes: "My apprentice, can you solve the doubts of the mentor?" ”

Lawson nodded without hesitation: "It's natural." ”

Having already dried his clothes, he took out a pen and paper from the table, wrote down the structure and principle of the lightning rush spell on the paper, and presented it to Thrandis with both hands.

"It's a four-star spell."

It was also the most complex spell Rosen had ever created, and it was written on four pages.

The snow-white and unstreaked snow paper was grabbed by the mage's hand and suspended in front of the young mentor, who was eating dessert and reading at the same time.

Looking at it, the action of eating dessert gradually slowed down, and even stopped, and almost all the spirit fell on paper.

Originally, she thought that she could easily understand it, because among the spells she mastered, there were many 7-star, 8-star, or even 10-star spells.

But soon, she found that although she could easily see the structure of the spell, she did not understand the principle of the spell.

After a few minutes, she decisively gave up her own exploration and asked directly.

"My dearest apprentice, your spell has stumped the Mentor, and that's a remarkable achievement."

Rosen chuckled in his heart: 'Expected. ’

Because the world's understanding of the material world is still superficial, there is a huge cognitive barrier to those slightly deeper knowledge on the earth.

Of course, it can actually be explained in layman's terms.

He looked humble: "Mentor, this is the inspiration I gained when I observed the falling apples. ”

"Oh?"

Thrandis looked directly at Lawson, wondering what the drop of an apple could have to do with a spell.

Rosen went on to explain.

"Mentor, have you noticed that when the apple falls from the tree, when it is still in the air, it is intact from beginning to end, and only the moment it hits the ground, the skin will be broken by the stones on the ground."

"Hmm~~ yes."

Rosen continued: "That would be very strange. Because when the apple falls, the speed is getting faster and faster, why is it undamaged? ”

"Because the speed doesn't change fast enough."

Thrandis guessed.

Rosen shook his head slowly: "At first, my mentor and I had the same idea, but I soon found out that this was not right, because it did not correspond to reality. ”

He scooped a spoonful of the rich milk cake from the dessert box on the table, and with a twist of the spoon, he let it fall to the ground with a 'snap' sound.

Then he asked, "Mentor, have you noticed?" ”

Thrandis thought for a moment, and shook his head dryly.

"I didn't find out."

Rosen reveals the mystery.

"Mentor, the milk cake is so soft that even if you touch it lightly, it can leave a mark on the surface, but when it falls, its shape is almost completely unchanged."

"If the damage to an object is caused by a speed that doesn't change fast enough, where is the limit between speed and slowness?"

Under Rosen's guidance, Thrandis finally began to break down the inherent knowledge barrier.

"So, it's not the speed that changes that causes the breakage, it's because ....... Why? ”

She had an inspiration in her mind, but it was vague and difficult to describe in words.

Rosen gave a straightforward answer. "It's because the speed of each part of an east and west changes at different speeds."

"In other words, the speed doesn't change evenly enough!"

This sentence was like lightning, and it split the fog in Thrandis's mind at once, and made her conscious world clear.

She gasped: "Ah~~ It's the breath of truth!" ”

After being shocked, she immediately followed Rosen's explanation all the way to it.

"Because some accelerate fast and some accelerate slowly, they tear each other apart. Because of the tear, it breaks, that is, damage! ”

Rosen immediately sent a rainbow fart.

"Mentor, your comprehension ability is truly enviable."

Thrandis's cheeks were slightly red from the slap of the sycophants, and she was a little embarrassed.

"My dearest apprentice, when you flatter your mentor in the future, you should pay attention to the strength, if the strength is too heavy, the mentor will also be shy."

After Rosen's explanation, she thoroughly understood the principle of the spell of Extraordinary Rush.

"So, you're simulating a fall?"

"Yes, first quickly fall down to speed up, drop almost, and then quickly throw up to slow down."

"In my imagination, I fell very fast, and in the blink of an eye, I could drop 100 meters."

"Of course, I can't really fall this far, because I will hit something, and it will break bones and tendons, and even fall to death on the spot."

"In the end, because my knowledge of magic is limited, and my mana is too thin, I can only accelerate to the level of a low-level peak warrior, and no matter how high it is, it can't be even."

It's uneven, then it will really break the neck.

Thrandis took the dessert in his mage's hand and clapped his hands gently.

"Ah~~~ My dearest apprentice, I have to praise you for your wisdom in discerning the truth. Compared to this kind of wisdom, the realm of mana and spell-casting skills are just low-end skills. ”

Lawson shook his head: "The last skill in the master's mouth can easily destroy me." ”

"That's right, so you still have to stick to hard work."

She couldn't help but admire: "Ah~ My dearest apprentice, I am now very much looking forward to your growth, maybe in the near future, you will shine brightly in the entire golden land." ”

Rosen humbly bowed his head: "Mentor, it's not a good thing to hold a little sparrow to the throne, it will be flattened by a real big man!" ”

"Hahahaha~~"

Thrandis couldn't help laughing, and sighed after laughing: "Hey~ You're always so sober." ”

After speaking, her face was solemn: "This lightning rush is not powerful, but it is extremely valuable. Its principle has opened up a whole new path of magic. ”

"Writing a spell paper with this spell and submitting it to the Mage's Guild is enough to get you quite a good reputation. Do you want to pay it? ”

Rosen asked rhetorically, "Does the tutor think I should pay it?" ”

Thrandis thought for a moment and nodded.

"Fame may be a burden, but it is also a protection."

"The big guys will crush an ordinary bug without any psychological burden, but if the bug is made of pure gold, they will love it. If it's made with flawless gemstones, it's even more careful. ”

Rosen said: "Mentor, my knowledge of spells is all taught by you, without you, I would not be where I am now, let alone this spell." If I do write this paper, I hope you are the first author. ”

"No, the first author is you, and I'm not one of those unscrupulous mentors who like to usurp the wisdom of their apprentices. I'm honored to be the second author. ”

In this case, Rosen nodded: "As you wish, mentor." ”

Putting away the spell papers, Thrandis picked up dessert and ate it again.

Lawson began to clean up the flattened milk cakes on the floor.

As he cleaned up, the title of 'King of Neverwinter' suddenly flashed through his mind.

With a move in his heart, he asked, "Mentor, the real culprit involves a powerful evil spirit, does it need to be reported to the Mage Guild, or even the Pure World Sanctuary?" ”

Thrandis nodded: "I have to report it, but we have to wait until we deal with it."

"Why take such a risk?"

"My clever apprentice, there is still a bounty on the real murderer, the bounty is already as high as 200 crowns, don't you plan to make a fortune?"

Lawson understood, and spread his hands: "What a reason that people can't refuse." ”

'Hee-hee~~'

Thrandis smiled lightly, and after eating dessert in a few bites and wiping the corners of his mouth, his face became serious again.

"Okay~ The mentor now knows my dearest apprentice very well, and it's time for my dearest apprentice to get to know the mentor well."
