The Witcher: Son of the Planes.

Five years flew by.

In addition to the mandatory tasks issued by the academy, Colin has been studying all the knowledge he can under Lina's dedicated teaching for the past five years.

Helen and Nora have made considerable progress, but it seems that one is more interested in doing experiments, while the other is more interested in doing business? Oh, this is putting the cart before the horse.

After five years of study, Colin finally caught up with the knowledge reserves of apprentices of the same ability. He also participated in many experiments. Colin and Helen even bought a set of experimental equipment on their own. They can now make some basic potions and gadgets. Finally, he is no longer called a newbie.

The contact with Edith was smooth and frequent in the first year. Helen seemed to have no idea about it, but they lost contact in the next four years. Colin didn't know what was going on. He always wanted to visit the North, but firstly, he had no reason to go, and secondly, he couldn't go unless he left the college.

Colin has always maintained good relationships with Connie and her siblings, as well as Marcus, Don Quixote and others.

During this period, friends from the underground world contacted Colin many times to buy food. Later, Colin simply handed over the business entirely to the Jade Collar Shop outside the college.

Colin had also asked his cheap father-in-law, Baron Richard, to look after his parents. After hearing the news that they were safe, he felt relieved. He would go back to see them after his strength had further grown.

After several years of study, Colin's understanding of magic has improved a little, but the greater progress came from an experiment, an experiment he experienced personally.

A year ago, he finally understood why Boggs had that expression when he became his apprentice. He was still deceived by Teacher Lina.

Although the academy prohibits experiments on the natives of the wizarding world, voluntary ones are not included, with the exception of dark wizards, because their group simply ignores the laws of the wizarding world.

Colin still couldn't resist Lina's temptation. When she taught him a lot of spellcasting techniques, especially the techniques that could shorten the time of his compound spells, he only considered it for less than a minute before agreeing to become an experimental subject.

Lina's experiment was to carve some kind of magic circle on his body, and his compound spells were also connected to this magic circle.

In this regard, Lina did not lie to him. According to Lina, she had already experimented on sub-humans many times, and the chance of failure was less than one percent. Colin was skeptical about this, but things had come to this point, and he could only hope for success.

Finally, the magic circle was successfully carved, and Colin could also feel that the speed of mobilizing his own magic power was obviously much faster than before. It was indeed much faster to cast spells, and it was not much slower than some single spells. Colin's strength had indeed improved.

There are still some useless materials on Earth. Probably only part of the content of Lina's experiment was recorded, so Colin couldn't learn from her even if he wanted to. He can only do it later.

Colin luckily survived a mandatory mission half a year ago, but his temporary teammates were disabled by Warcraft and their way forward seemed almost blocked.

Thanks to Colin's experiment, he was able to deal with the monster with his calm response and steady and quick spellcasting.

After learning the meditation method from teacher Lina, Colin's mental power grew to 16 points in just five years.

He had finally reached the limit of a high-level wizard apprentice. Now he could be called a quasi-level wizard apprentice and was only waiting for the next step of promotion.

Most of the rewards from the college competition five years ago have been used up, leaving only a bottle of high-level mental power potion. This potion is most effective when used for the first time, so Colin has never been willing to use it, thinking of using it for the next step of promotion.

But this potion alone is far from enough. You must know that the starting mental power of a formal wizard is 20 points.

He didn't know how others made the breakthrough, but what Teacher Lina told him was that if he kept compressing his mental power until it couldn't be compressed anymore, he would naturally be able to advance.

During this time, Colin also flipped through a lot of books on the subject in the library. The contents were all kinds of strange. Some of them seemed reliable, but upon closer inspection, they were still not acceptable.

If he fails once, the next breakthrough will be much more difficult. Colin only wants to succeed once.

While looking up information by chance, Colin found a very niche book in the library, which talked about the method of compressing mental power.

Colin felt that it must be the blessing of the goddess of luck, as if he had found a pillow just when he was sleepy.

After borrowing it, I opened the book and was a little disappointed. It was a lot of nonsense. I felt that the person who wrote this book must be a slacker. I don't know how many merit points he got by handing in this book?

Fortunately, after reading this book, I finally summarized three methods to stimulate the growth of mental power.

The first method is to continuously cast spells until the magic power is exhausted. After long-term practice, the upper limit of mental power will naturally increase.

Colin knew about this method without even having to look it up, but the growth effect was very weak. It could be used as a routine measure, but it was not very meaningful.

The second method is to integrate into the blood of the Warcraft and use the powerful blood power of the Warcraft to break through the shackles.

Colin had heard of this method before, so let's just consider it as an alternative plan. However, I don't know where to find a powerful monster for the moment, so I can ask the teacher for help.

The third method is to refine a blood-burning potion. It is said that when a person officially breaks through, it can stimulate the growth of mental strength by burning his own blood power, thus achieving the effect of breakthrough.

There is a method for refining this kind of potion in the book, and it looks like it is not difficult to refine. Other materials are available on the market, but the main ingredient needed is the heart of an underground bat, which can only be found in the underground world.

Colin was a little tempted, he had friends in the underground world and was not unfamiliar with it, but the recent mandatory mission was about to arrive, so he needed to complete this one.

Although Helen has been studying and practicing hard, and is not slow compared to her peers, she is a little hesitant about Colin's obsessive practice attitude.

Life is not just about cultivation, it is also about himself and Nora. Could it be that he and Nora can no longer satisfy his curiosity?

Do you want to pull Connie into the water?

However, Colin, whose thoughts were completely different from Helen's, was thinking about going to the underground world.

Colin, who didn't want to waste time, finally found Teacher Lina. On the one hand, he asked about the three methods, and on the other hand, he paid a considerable price (merit points) to find someone to replace him and carry out the mandatory task.

Fortunately, this kind of situation does exist. The academy only requires the task to be completed, and sometimes it will turn a blind eye to who it is.

After successfully avoiding a mandatory mission, Colin finally discussed with his family and set out on a journey to the underground world alone again.
