Qin Ming walked from one end to the other along the corridor, and he had a general understanding of the contents through those door numbers.

Although there are many compartments, they are only subdivided into some categories.

Taking the spirit stone as an example, the spirit stone is directly subdivided into three grades, ordinary spirit stones, high-grade spirit stones and top-grade spirit stones.

In this way, if you want to exchange for the best spirit stones, you can go directly to rooms 8-11. And in these rooms, the best spirit stones are divided into four categories: nature, law, biology and special. Each type of top-grade spirit stone also corresponds to a corresponding room, unlike when you are on the lower floors, where you need to find the one you want to exchange from a pile of things.

After refinement, it was indeed much easier to find something, but Qin Ming was not interested in these changes, what he was interested in was that this layer had something more than the following layers.

In fact, this layer is also true, there are many things that are not found in the following layers. In total, there are 5 categories. They are storage rings, basic skill books, advanced skill books, spiritual power scrolls, and spiritual weapons.

Storage rings must be something very worthy of their joy for those freshmen and some sophomores, but for a person like Qin Ming who has multiple storage rings in his hands, this thing is almost the same as a bad street, so he doesn't feel rare at all when he sees it.

What he was really interested in was the other four new items.

He also knows more about basic skill books, because like his Fire Snake Technique, An Zili's Healing Technique, and Bai Ling'er's Shadow Killing Technique, etc., these are all basic skill books.

Although the exchange price is not very high, it is not low, 100 learning points per book. Whether it is a law system, a natural system or a special system, it is a uniform price.

And it is also divided into two types above: defensive and offensive. There are 5 basic skill books for each category and each attribute that can be redeemed. Three types of attack and two types of defense.

Qin Ming first looked for the skill book of the fire attribute, and found the fire snake technique he practiced on it, which was a skill book belonging to the attack class. As for the other two attack skill books, they are both a bit LOW in their names.

Because one is called fireblowing, and the other is called firelight.

The other two defensive fire attribute skill books are Fire Escape Technique and Fire Wall Technique.

After Qin Ming read these basic skill books, his eyes couldn't help but fall on an advanced skill book placed on top of it.

The level of the skill book is similar to that of the spirit stone, and there are three levels, which are basic, advanced, and top.

The basic skill book, the spiritual power running route, is very simple compared to the advanced skill book, not complicated, and the spiritual power required is relatively low, and the power is naturally weaker. You only need to enter the threshold of the spirit level, that is, to give birth to spiritual power, you can cultivate.

However, the high-level skill book requires the strength of the spirit infant level to cultivate, because the spiritual power required to complete the spiritual energy is too large, and the spiritual body level cannot withstand its consumption in terms of spiritual power reserves, even if it is barely released, he will die violently because of the extreme overdraft of spiritual power.

Therefore, even if someone can obtain a high-level skill book, if their strength does not reach the spirit infant level, they will definitely not dare to cultivate, otherwise they will likely die violently in the process of cultivation.

Of course, although the spiritual power required by the advanced skill book is huge, the power released is also devastating. It's not like putting a few primary psionic abilities in a row can be compared.

This is like the difference between a cannonball and a bullet, even if you shoot dozens of bullets in one go, the destructive power cannot catch up with the landing of a random cannonball. This qualitative gap is even more pronounced especially when faced with very difficult targets.

It stands to reason that Qin Ming's current fire spirit has only just stepped into the threshold of the spirit level, not to mention that the reserves are very small, but they are also very limited, he should not have studied the advanced skill book, but he is not only studying it seriously, but he also has a strong desire to exchange it in his heart.

Because although his fire spirit is not good, his dark attribute is enough to withstand the consumption of this high-level skill book. Not to mention, there is still a slight possibility of the two superimposing.

Even if it can't be stacked, his dark attribute is enough to exert the power of this high-level skill book, and maybe there will be unexpected effects.

If he can master a powerful high-level spiritual energy, then there is another guarantee, after all, in terms of executing events, he will always encounter various unexpected situations sadly, and there is a high probability that he will encounter a lot of powerful sneakies, so high-level spiritual energy is something he desperately needs.

"Yan Yu, this name sounds pretty good, that's it!"

Qin Ming made up his mind in his heart and changed this advanced skill book, but he didn't change it with a slap of his head, but looked at the advanced skill books of other attributes.

However, after weighing it, he still decided to change this advanced skill book of fire attributes, because this exchange is equivalent to being able to use two books. As for the skill books of other attributes, he also had other channels to get them, after all, for people who had already mastered spiritual energy, skill books were just a piece of waste paper.

In addition, not many people know, or even think, that his dark attribute can imitate the spiritual energy of all attributes. A skill book of any attribute is useful to him.

He had actually thought about it, even if it was An Zili's life attribute skill book, his dark attribute could be cultivated. As far as healing is concerned, his dark attribute itself certainly does not have the effect of healing, but it has the characteristics of corrosion and devouring, so it can be used as a devouring technique.

To put it bluntly, his dark attribute is imitation, and what cannot be imitated is exactly the same, in essence, it is still the spiritual energy of the dark attribute, but he can draw a scoop according to the gourd, and achieve the most basic god-likeness. But as far as psionic energy is concerned, it is essentially a form of spiritual power display, so as long as it can be godlike, it can be regarded as a successful imitation of most of it.

Qin Ming still had 50 learning points left in his hand last time, plus the 300 learning points he got this time, there were still 300 points in total, and the price of an advanced skill book was just 350 points, so he just could afford it.

Although there may be better things going up, Qin Ming does not regret spending his studies, because he can't care about the future, and in his opinion, what is most important is now. He has to get through this weak stage before he can have a chance to fight for the future.

It's not that you have to look at things and only stare at the present, of course, you have to think about the future, but just think about it, and you must not be too involved, because people still live in the present after all.

After changing the skill book, Qin Ming looked at the spirit weapon and the spirit power scroll again.

Spiritual weapons are weapons that have been forged by spiritual power, like a sword and hammer, it may be useful to deal with sneaky things, but in Qin Ming's opinion, these are all foreign objects, and they can be considered if they are relatively sufficient to learn, but forget it now.

As for the spiritual power scroll, it is a kind of scroll that stores spiritual power, although it is storage, it is also called a scroll, but in fact it is neither a spiritual scroll nor a spirit stone, but as the name suggests, it is a combination of the two.

The spiritual energy stored in the scroll cannot be inhaled into the body, but it can stimulate the spiritual power above it to make it work and release spiritual energy.

After Qin Ming learned about it, he felt that this spiritual power scroll was very chicken, and the exchange price was not advantageous compared to the spiritual energy scroll, so there was no need to even think about it.
