This black book, which appeared in Bai Xiao's sea of literary knowledge, has a pure black cover and no title.

Moreover, compared with the "Taigong Art of War" and "Taixu Sutra", the black book is obviously one size smaller, and it is very thin, and it is shrouded in a layer of pure black light.

"Another professional book?"

Bai Xiaowen tried to inject spiritual sense into the black book, but when he tried to read it, he found that he couldn't "lift" the cover of the black book with all his might.

Won't open!

Bai Xiaowen frowned.

Unable to open, there are several possibilities. The biggest possibility is that the black book is still in a state of incompleteness, so it cannot be read.

Judging from the comparison between the black book and the previous two professional classics, it is still obvious that although the black book has a high-end style and a high-grade atmosphere, and the pure black light shrouded in it is like a black hole that can swallow the sight, but the black book itself is still too slim, and it is one size smaller.

Bai Xiaowen withdrew from Zhihai, although he was very curious about what was recorded in the black book, but he was not too anxious.

Anyway, Bai Xiaowen has already cultivated two professional classics, and there is no way to cultivate the third one, unless he finds a way to open the three professions, but Bai Xiaowen thinks that it should be unlikely, dual professions are already extremely rare, and the difficulty of the three professions is not just as simple as doubling, to say the least, it has to be increased by five times or ten times, and there is even no way to open the three professions at all.

It is impossible to abolish the "Taixu Sutra", right? Because there is no way to change the original professional classic "Taigong Art of War".

Even if you ruthlessly abolish the "Taixu Sutra", whether this black book can be cultivated is a big question......

Thinking of this, Bai Xiaowen suddenly froze:

[No! This black book is not a professional classic!]

If it is a professional classic, after Bai Xiaowen starts with it, he should get a hint of the cultivation fit, such as the fit with the "Taigong Art of War" or the "Taixu Sutra", to remind whether the evolutionary meets the cultivation requirements.

Bai Xiaowen opened his eyes.

Since the Black Book is not a professional classic, it is similar to the "Grass Sword Soul", a strange thing that is placed in the body of the evolutionary?

The difference is that the Grass Sword Soul is currently housed in Bai Xiaowen's Dantian Qi Sea, surrounding his spiritual power core True Yuan Force Light Ball, which rotates like a satellite, while the Black Book is housed in Bai Xiaowen's Eyebrow Mind Consciousness Sea, which exists on the side of the two professional classics.

Bai Xiaowen had tried to communicate with the Grass Sword Soul with True Yuan Force, but he was able to get a response from the Grass Sword Soul, but he couldn't use it as an attack skill to play out of the body, so he thought that he lacked some kind of precondition, so he didn't do it.

Bai Xiaowen thought about it for a while, and made another attempt, that is, to guide the True Yuan Force into the Sea of Knowledge, trying to communicate with the Black Book, and see if this strange thing could be used by him.

After all, it was his own knowledge of the sea, unlike the confusion spell that invaded other people's knowledge of the sea, Bai Xiaowen was still very careful, and only used a trace of true yuan power to test it at first.

Who knew that this trace of true yuan power, after coming into contact with the pure black light on the surface of the black book, disappeared directly, as if it had been completely devoured!

Bai Xiaowen was shocked in his heart, and immediately looked inward and checked himself, and found that there was no abnormality in his body, but the true yuan power had been consumed by about ten points.

Bai Xiaowen tried again, and this time the output of the True Yuan Power increased to 20 points.

Then, again, he was blacked out and all accepted.

30 o'clock! 40 o'clock!

Bai Xiaowen slowly increased the input True Yuan Power.

When the fourth attempt, after entering 40 True Yuan Force, the Black Book finally reacted.

The pure black light flashed slightly, and then a trace of pure black energy was "spit out".

This trace of pure black energy turned into a small black ball, which circled the black book like a satellite.

Later, Bai Xiaowen tried to continue to communicate with the black book and inject the true yuan force, but he was stunned to find that the pure black energy ball actually produced a strong resistance, preventing the true yuan force from continuing to communicate with the black book.

After all, it was his own knowledge of the sea, and Bai Xiaowen didn't want to engage in a Yuanli offensive and defensive war, so he could only stop.

[What is this pure black energy ball?]

With this question, Bai Xiaowen opened his eyes and began to habitually check himself for the last time.

In this self-examination, Bai Xiaowen suddenly found out that he was tired.

On Bai Xiaowen's personal panel, under the original "spiritual power value", a small column actually appeared.

[Death Power: 10/10]

What the hell is this "power of death"? What about the rules of the spirit world, such a big change in the attribute panel, why don't you come out to report it!

The power of the god of death is very high when you hear the name!

Bai Xiaowen was instantly excited, since it is his own energy, then I should be able to call it too, right?

Bai Xiaowen then tried it.

Then I found out that I was thinking too much.

These 10 points of death power should be the pure black energy ball that surrounds the surface of the black book.

At present, the pure black energy ball will not listen to its own will, that is to say, these 10 points of death power are just good-looking.

Bai Xiaowen shook his head.

When the friends saw that Bai Xiaowen had stopped, they all gathered around and asked what was going on, as if the mask of the face of death had swallowed the bones of the god of death.

Bai Xiaowen shook his head and said, "It's hard to say what happened, but there is no immediate improvement in strength." ”

Here, Bai Xiaowen did not mention the power of death and the black book, and kept an eye on it.

It's not that I'm worried about my friends, it's just that Bai Xiaowen feels that this kind of physical change that has not been detected by the rules of the spiritual world, it is best not to announce it. Perhaps it was the influence of his father Bai Yuantang that made Bai Xiaowen subconsciously always have a strong vigilance against things involving "gods".

Anyway, the Grim Reaper Hand Bone has now been collected.

Bai Xiaowen inserted the Resentful Spirit Banner (unfinished version) into the altar, and suddenly the Bone Mound Circle returned to normal again.

There are still some undisposed remnants of war, which are just right for experimentation.

Without the Death Hand Bone, the Wraith Banner (unfinished version) was changed to the core formation component, and the power of the Bone Mound Circle instantly dropped by more than one level.

The most obvious feeling is that the additional effect of "spiritual power aggregation" has been greatly weakened, and the concentration of spiritual power in this underground palace is rapidly declining.

Bai Xiaowen doesn't care about this, the spiritual power aggregation effect here and even in Chang'an City dissipates, and the concentration of the spiritual energy of the Tang Dynasty in the rest of the places will definitely be able to recover, anyway, it is all stuffy in the pot, and the spiritual energy will not run into the starry sky of the universe.

After devouring the corpse, the black mist produced by the Bone Mound Circle turned into a human form.

The newly produced soul creatures no longer have the strength of an evolutionary, which is about the same level as a level 3 awakener, but the number has increased tenfold, and more than a dozen have appeared at once.

It seems that this is the result of replacing the Grim Reaper's Hand Bone with a Wraith Banner.

"Wait a minute...... These weak soul creatures seem to contain a lot of business opportunities!" Bai Xiaowen suddenly came to his senses.
