Suddenly, a feeling of exhaustion swept through the body. Not that purely physical exhaustion, but mental. Tang Bai only felt that his head was a little swollen and painful at the moment.

Tang Bai, who had studied some magic systems and principles in Harry's world, immediately understood in his heart that this was the reason for excessive mental consumption. Although he didn't use magic in the sense of meaning, he also spent a lot of energy manipulating and constructing just now.

Not to mention the delicate manipulation of the five sawtooth ice trays.

Whether it is a sawtooth ice tray or a simple ice wall, if Tang Bai wants to release it, he also needs to shape the image in his mind in advance. Just like a thinking question, the more complex the topic, the more it takes mental and brain effort to think and analyze. And the more complex the graphics, the more difficult it is to shape.

It is the same as the soreness that consumes a lot of physical strength after exercising, resulting in tired muscles in the body. Mental exhaustion can also lead to a series of sequelae. Tang Bai's current spiritual power is several times that of ordinary people. But after a few minutes of meticulous control, the spirit inevitably fell into exhaustion.

The more focused you are, the faster your energy will be consumed.

Controlling five sawtooth ice trays at the same time, which is almost the limit, and having them make all sorts of completely different movements in the space of the bedroom in a matter of minutes, is definitely a burden on people.

After Tang Bai tried a few more easy attack methods, he dispersed all the ice tools and ice layers that had been shaped, leaving only the fine ice cubes evenly scattered on the floor. After doing all this, Tang Bai put away the golden wand in his hand again, put it back in the mirror world, and fell asleep peacefully on the bed.

got what he wanted, Tang Bai did not leave this world immediately. Instead, he took some extra time to become proficient in the use of the golden wand, and according to the previous agreement, he deliberately stayed for a full number of days before saying goodbye to Professor Diggory.

A few days of practice was not a waste of time for Tang Bai.

In the past few days, Tang Bai has tempered his spiritual power, and if the method is appropriate, he can consume some spiritual power appropriately, which can promote the growth of spiritual energy. If Mellen Watts and Gargerson and the magic books didn't deceive him.

Returning to the main world, Tang Bai began to think about what he would do in the future.

The original purpose was money, to improve the lives of yourself and your family. He had already fulfilled that wish. Although he is far from being a rich man now, the money in his hands is only enough for his parents and himself to live a comfortable and safe life.

What's more, Tang Bai doesn't want it now. His current strength has not yet reached the point where he is not afraid of anything in the main world. The current situation is very good for Tang Bai, who is bent on the fantasy world. As for other derived aspirations, he doesn't want to be too conspicuous when his own strength is not enough to protect his own interests.

The higher the level, the more fierce and dangerous the competition becomes.

Tang Bai had studied the system of magic, but it did not match his own existing power system. So it can only be used as a reference. Despite some effort, he was able to perform most of his magic with his wand in hand.

But if he wants to master the same magic, it will take more time than other wizards. If you want to use it proficiently, it will consume more time. If you can't turn it into a knee-jerk reaction anytime and anywhere, and release it like an arm, then the usefulness of this magic in battle will be greatly reduced.

Harry's world magic, in terms of lethality and utility, except for a few, ordinary people can also do it with the same technology. It's just that magic takes less time and is more convenient.

This kind of magic is fine in a world with a simpler power system, but if it is replaced by a world with a strong power system, how much effect it can play, Tang Bai dare not guarantee. But just from the power of those magic, I'm afraid it's not optimistic.

It is true that the same magic has different powers and effects when used by different people. For example, a fruit knife in the hands of a child is completely different from the deterrent and powerful power of a special soldier.

As long as Tang Bai's strength reaches a certain level, he can ignore the gap between the power systems of the two worlds. This statement does not seem to be wrong, but it only seems to be true. There are too many things in this world that seem to be reasonable but are actually unreasonable.

To give you the simplest and most unverifiable example, but everyone thinks like this in their minds, an immortal cultivator has soared from the lower world to the higher world, can you say that his strength and cultivation methods are comparable to the higher level worlds?

In the world of a higher level of power system, there must be a better power system and cultivation method.

In Tang Bai's opinion, there were only a few powerful and strange effects of magic in Harry's world that were useful to him. But these magic can be considered high-level systems. Learning them and mastering them doesn't happen overnight.

It's like a primary school student, it is impossible to learn the textbooks of junior high and high school at once without any accumulation, and master the knowledge in them. If Tang Bai wants to master those, I'm afraid it will take quite a lot of time.

Most of the other people can only be trapped in one world, so they can only cultivate and adapt to the power system of that world without choice. In Harry's world, those who succeed are called wizards, and those who fail are Muggles and Squibs.

But Tang Bai is different, he can have many worlds to choose from, and the power of the magic mirror is also extremely practical for him. There was no need for him to embarrass himself on this.

Potions system and learning, this is also a time-consuming job. Fortunately, Tang Bai's current entry is not bad.

The cultivation of the clover grass of life and death has now been regarded as a success. As long as it is said that the Fountain of Immortality is indeed effective against the clover of life and death, then the last shackle restriction on reproduction will also be gone.

The elixir made from the clover of life and death grass can also allow Tang Bai to obtain an extremely long life to a certain extent. Similarly, the effect of the clover of life and death grass can also make Tang Bai's physique and bloodline climb rapidly to a higher level.

In the end, the degrading means of attack were now temporarily solved by Tang Bai.

The next step, in front of Tang Bai, was left to figure out the composition and acquisition of divine power, as well as master alchemy.

The first purpose aside, it takes chance and time. It's useless to be in a hurry. The second goal is not difficult to achieve. Although the potions and alchemy systems in Harry's world are somewhat declining, they are still quite sound.

As long as these foundations are still there, given enough time, Tang Bai may not be able to get a glimpse of a higher level of alchemy.

What's more, as long as you collect more alchemy in other worlds and hand them over to Bogin Bock for thorough research, there is a great chance that the declining alchemy system will be greatly improved and improved.
