Wren didn't dwell too much on this, he was so hungry that he ate the grilled fish as if he were devouring dates.

Seriously, this kind of secluded life, he can't stand it anymore.

The valley is complete, and some mineral salts have been found for Wren. After making the activated charcoal, Wren barely managed to get a little fine salt out by boiling the salt.

A small amount of fine salt is used to make do with it, and the grilled fish will not be unpalatable, but it will be greasy if you eat too much.

Wren was already looking forward to the carrot and tomato seeds that had been planted earlier.

There was expectation, but not much.

This is not the vegetables and fruits that have been cultivated and selected in the Earth Celestial Empire, and the carrots he dug up before are a little bitter.

It's just that Downs saw Wren's operation of boiling salt, as if he was watching alchemy......

In the days that followed, Wren changed his ways to toss Downs.

"A good memory is better than a bad pen. There's no paper here, so give you a week, and you copy the terms of voltage and electric potential 30 times and engrave them on the stone wall. Wren casually pointed to a black stone wall the size of half a basketball court, and said, "Each word must not exceed the size of a Kaos gold coin, and the depth of the word is about 5 millimeters." ”

With that, Wren dropped a knife.

Downs, under his tutelage, certainly knows how deep 5mm is.

After Wren left, Downs tried to carve with a knife, and as soon as he got his hands on it, Downs realized that something was wrong.

The texture of this stone wall is very strange, and it seems to be a little soft on the outside, but in fact, when the blade penetrates 2 mm, the resistance generated by each 1 mm rises geometrically.

Downs, who was born as an apprentice knight, used all his strength to feed, but he only pierced the first stroke into the wall to meet the teacher's requirements.

"Nope! That's not right! Master's instructions must have a deep meaning! I'm a mage, what do I need a knife for? This knife must have been a trap for the master. Think...... I keep thinking hard! Master first asked me to peel the scales of the fish, then control the fire element to grill the fish, and finally this is the obsidian wall......"

Downs pondered for a while, as if an illusory lamp lit up in his head: "I understand! It was in this way that Master exercised my skills to make my control of the elements more refined. I'm not going to use a knife, but I'm going to use the fingers of the [Electric Claw] to copy the principle 30 times, stroke by stroke! ”

I have to admit that even if a certain master comes in person and asks him to carve with a knife, he will definitely not be able to do the tricks that a guy like Downs who is full of skill and talent can do tricks.

For seven days in a row, Lei Enjing ignored his disciples.

Except for throwing the disciples to carve stone walls, that is, letting the disciples deal with live fish, and getting a hand in kitchen affairs, he did not even teach any new physical principles.

Downs was not annoyed at all, calmed down, and used the electric knife to engrave the Kaos noun explanation seal inch by inch.

Happy times are always short-lived.

These days, Wren has lived a life of eating without having to work, and he is really a little reluctant.

On the eighth day, Downs came to hand in his homework.

If Wren was a true mage, he would be able to see the faint magic emanating from his disciples, and the words on the walls were not carved with a knife, but with an electric knife.

Wren fluffed a sentence: "It's okay." ”

As everyone knows, Tang Si really breathed a sigh of relief in his heart: Master is strict with me, it turns out that I have done this, and it is just a 'okay' comment, it seems that I am not talented, I have to work harder.

Tang Si bowed respectfully: "May I ask Master, what am I going to learn next?" ”

Very abruptly, Wren said coldly: "I'll teach you another law of physics, once you successfully comprehend it, you will be a teacher." ”

Downs' face was full of astonishment, and he said incredulously: "Ah! No, this, Master, is too sudden. I don't think I've learned enough. ”

"Do you think you're still a powerless apprentice in magic?" Wren's eyes lit up.

"I ......"

"Throughout the ages, existences that can master three magic levels above level 1 will be recognized by the world as official mages. As I said, Master leads you through the door, and the practice depends on the individual. Wren put his hands behind his back, his chin raised 45 degrees to the sky, and looked unruly: "First of all, I'm not your official master, I'm just happy for a while, and I'm just pointing you out." And I teach science, not magic, and I am not obligated to train you to be an archmage. ”

Wren pushed Downs out, but after all, he was weak-hearted.

He really didn't know how far he could teach Downs with this kind of hellish way of teaching. Perception is a thing that is not working from time to time. If you can realize the Tao every time, it will be too rebellious.

After all, this broken system has not given a single official magic from beginning to end, nor has it had a single incantation. Since he can't systematically conjure up a set of magic, he, the 'archmage', is easy to goof.

When Downs got stuck and couldn't comprehend anything new, and Wren couldn't teach Downs, that's when it was over.

Moreover, at the beginning, Downs went bankrupt and sold the family heirloom armor in exchange for more than fifty gold coins, and now that Downs is about to become an official mage, Wren has received 'peace of mind'. But if he continues to teach, if Downs really hits the fortune and becomes a legendary high-level mage, it will be Wren's turn to feel a big loss.

Wren didn't know what the prices were outside, since there had never been a mage in the world for a hundred years, the value of a high-level mage should definitely not be equivalent to a set of treasure armor.

Anyway, Downs has become an official mage, and wherever he goes, he has to recognize Wren as a master.

Downs, who was born as a knight's apprentice, really can't squeeze any oil and water.

Rather than being too risky, it's better to stop at the point.

Wren's words made Tang Si's mouth squirm for a long time, he was puzzled at first, and then immediately decided that this was the insurmountable principle of this hermitage archmage. It's not that Master Wren refuses to teach, it's that his talent is too poor to get into the master's eyes.

"Master, I would like to ask, how can I become your personal disciple?"

Wren gritted his teeth and decided to raise the bar high, so that this kid would die: "Wait until you become a legendary mage." ”

Downs's breath quickened.

O legendary mage! It was a presence that had been praised by bards for ages. Sure enough, does it take such a great existence to be qualified to become a personal disciple of the master?

"I, I know. If that day comes, I will prepare a very solemn apprenticeship. Downs bowed deeply.

"Huh! Apprenticeship...... There was once a king who put his whole treasury before me, and I didn't even ask for it, because his children didn't have that talent. "Boasting about not paying taxes, Wren blows straight to the sky.

Anyway, in order to prevent Downs from getting nervous and running over again, Wren desperately added extra conditions to this kid.

Wren didn't believe that this kid could become a legendary mage at the same time, and he also had the ability to hack the treasure house of a kingdom to him.

Tang Si immediately understood: the apprenticeship master can decide whether to accept it or not depending on the mood, but the etiquette must be done sufficiently, at least the wealth of a country's treasury to be worthy of the master's status.

Tang Si didn't know that his master was essentially a layman with money, so he saluted extremely seriously: "Master! I see. Then ...... Please ask Master to guide me in my last lesson. ”
