Hiding near the Blood Demon Gate, which had become a sea of fire, Huo Hai flipped through the books of the Blood Demon Gate and began to read it. Before leaving, Huo Hai also looted all the space items on the upper floors of the Blood Demon Gate.

I believe that even if I miss something, these guys will carry it with me. The more he looked at it, the more helpless Huo Hai became. I don't know who created the secret cultivation method of this bloody sect, but most of them are very evil things. Killing directly with your own hands is already the most common one. There are also some more complex.

For example, devouring the blood of living beings in large quantities, and some secret methods such as torture and then killing people, and so on. If there are enough people for them to kill, their strength can improve very quickly.

It's a pity that the secret method of the Blood Demon Gate can only raise people to the Spirit Emperor realm at most. If you want to continue to improve, you can't do it by relying on this method. His own murderous qi and blood qi exceeded the level of his own spiritual power and spiritual suppression.

When the time comes, once they are counterattacked, none of these people will have a good end. Of course, they won't care too much, because the secret method of the Blood Demon Gate requires too many killings. Even if they had been killing for so many years, none of them could reach the seventh-level Spirit King, let alone the unattainable Spirit Emperor realm. It's really a sect that is evil from the root.

Huo Hai shook his head and continued to look at these things, Huo Hai had no intention of cultivating. Similarly, Huo Hai didn't think about destroying it. In the future, maybe it will be of any use, Huo Hai thought to himself.

After all, this is also a shortcut to cultivation, Huo Hai wondered, can he go to the Vast Land Empire when he can do it.

Continue to read, when he opened a red book, Huo Hai finally felt a light in his eyes: "The bloodthirsty magic knife, collected the essence blood of all living beings to condense the ......" Huo Hai finally found the relevant information of the blood blade.

"It turns out that this thing is called the Bloodthirsty Demon Knife, and it looks like this, it's really an evil weapon. Huo Hai finally knew what this thing was made of. It turns out that the blood of the entire mountain exists for this knife. Almost every once in a while, the blood collected from all over the country would be sent to the headquarters and then poured into the mountains.

Through the spirit array arranged on the mountain, the amount of power in the blood is absorbed, and then used to refine the bloodthirsty magic knife. This knife was originally made of ordinary materials, but with the absorption of a large amount of blood, the material has completely changed.

At this time, the quality of the long knife has reached the peak of the lower grade of the prefecture, and it is about to enter the middle grade of the prefecture. It's a pity that the Bloodthirsty Demon Knife is not something that ordinary people can use at all, even if it is a person from the Bloodthirsty Sect.

The magic knife is naturally very demonic, as long as someone picks up this knife, they will be eroded by the negative force contained in the knife body. When Huo Hai took it before, if it weren't for the help of the Divine Technique, maybe he would have been killed and occupied in his heart.

However, this bloodthirsty demon knife is not useless, because it is actually a rare growth type weapon. With the continuous killing, the more and more powerful masters are absorbed, the stronger the power of the Bloodthirsty Demon Knife will be, and theoretically, it can even be improved all the time. As for how far the final height can reach, it is not up to Huo Hai to guess.

The Blood Demon Sect rarely fights with people, because their own strength is not too strong. Therefore, it is just to use civilian blood to hone this bloodthirsty demon knife little by little. For thousands of years, this knife still has not reached the middle grade of the prefecture.

Moreover, no one in the entire sect dares to use it. Originally, this knife was the most powerful means used by the Blood Demon Gate to die with a strong enemy, but I didn't expect the special spirit trick of the Blood Demon Gate to cause the murderous aura on everyone's body to be very strong.

After reaching the most luan, he was killed by Huo Hai, and no one even thought of using the bloodthirsty magic knife. This bloodthirsty demon knife finally came into his own hands. It is also recorded in the books that if you use the Bloodthirsty Demon Knife for a long time, you will eventually become completely integrated with the Demon Knife. Although its strength will be greatly improved, it will become a machine that only knows how to kill.

Whether he can come to his senses or not, no one knows what to do, even the person who invented the bloodthirsty magic knife has never thought of this problem. Perhaps, since the birth of the Bloodthirsty Demon Knife, no one has really used it.

Huo Hai shook his head, and his heart was even more jealous of the Bloodthirsty Demon Knife. It's better to throw this thing away in a corner. God knows if this thing has any effect on his spirit worm. Huo Hai didn't want to leave any hidden dangers in the future because of his negligence. Even, Huo Hai also set up a formation in the inner space to isolate the breath of the bloodthirsty demon knife.

Although this bloodthirsty demon knife is more evil, it does not have its own spiritual intelligence. Without the control of its owner, the Bloodthirsty Demon Knife was quiet, like an ordinary long knife. After doing all this, Huo Hai breathed a sigh of relief.

Putting down the matter of the magic knife, Huo Hai continued to watch. After all, the spiritual formula he really needs, Huo Hai has not found it yet. After this battle, Huo Hai became even more eager for the secret method of cultivating murderous qi.

Who knew that the people of the Bloody Gate would actually contain so much murderous aura in their bodies. Killing an ordinary disciple is also as much murderous aura as killing hundreds of low-level spirit masters, otherwise how could Huo Hai be temporarily eroded by murderous aura.

Huo Hai could feel that the murderous red ball behind him was about to reach its limit. If it weren't for Huo Hai's efforts to suppress it with his own spirit and spiritual power, he would have controlled it. Maybe one day, this thing will completely explode.

Such a terrifying murderous aura now makes Huo Hai feel like he is cocooned. If it completely broke out, Huo Hai was sure that he would definitely not end well. Becoming a murderer is already a good thing.

It was precisely because he had been controlled by murderous qi several times that Huo Hai hated this feeling even more. That kind of muddy, I don't know anything, and I don't even know that someone died in his hands, Huo Hai really doesn't want to try again. If you accidentally hurt your friends and family, it will not be enough to atone for your sins.

The relatively ordinary books, when Huo Hai finished reading them, he didn't find them, because most of them were secret methods for collecting blood qi and murderous qi, and then using them to improve his strength. For Huo Hai, it was really useless.

The secret methods cultivated by the high-level of other sects were of no use to Huo Hai, until he saw the most difficult ones, and Huo Hai finally found what he wanted. Huo Hai, who originally thought that he was about to find what he needed, finally breathed a sigh of relief.

"Condensation Technique, the secret method of the Bloody Demon Gate, hehe......" Huo Hai sneered in his heart, in the eyes of the people of the Blood Demon Gate, it is the partial door, and in Huo Hai's opinion, it is the real righteous path. Condensation is about condensing one's own evil energy.

In fact, the murderous aura itself is also a kind of evil qi, but the murderous aura is generated on living beings, and it is produced along with killing, so it is distinguished from ordinary evil qi. Condensation is a secret method that collects a large amount of evil qi and then condenses it. Because the Blood Demon Sect does not have its own perfect gathering of murderous energy, it is similar to the secret method of the Blood Condensation Sutra.

What's more, the evil qi required for the Condensation Technique is too much, so the Blood Evil Sect will regard the Condensation Technique as a kind of side door. This bloody sect is really going the wrong way, and Huo Hai has nothing to say about this kind of sect.

The so-called Condensation Technique actually has two different cultivation methods. One of them is to collect a large amount of evil qi and then use it to condense weapons. The higher the quality of the weapon you put into it, the better the tempering effect will be. In the same way, the more evil qi is consumed in this way. In fact, the Bloodthirsty Demon Knife is a method that evolved from the Condensation Technique.

It's just that the Bloodthirsty Demon Knife is not like the Condensation Technique, which is condensed with the evil qi on a person's body, so it will not be controlled by anyone at all. The weapon tempered by the Condensation Technique is powerful, but it is also absolutely under the control of its master.

The disadvantage is that it can only absorb the evil energy provided by the owner, and cannot absorb other things to improve itself.

This method, although Huo Hai was excited, he didn't like it very much, the murderous aura on his body was indeed very strong, but it was impossible for Huo Hai to take the initiative to absorb a large amount of murderous energy. It has a lot of murderous energy, but sooner or later it will be used up one day.

Huo Hai was more inclined to the second method of refining, which was the method of refining the soul of evil qi. First of all, you have to collect a lot of evil energy, and after that, you have to find the soul of a powerful creature. This creature must at least reach the ground level, after the soul itself has undergone transformation. Preferably the kind of creature that is born with a strong bloodline, and can even regenerate its intelligence in the future.

The method of killing qi refining souls actually consumes more murderous energy, but it can permanently solve Huo Hai's own problems. The stronger the soul essence, the stronger the strength in the future. The murderous energy consumed is also more.

Even if this murderous soul dies in the end, the murderous spirit will dissipate, and it will not return to itself, let alone eat itself, such a bottomless pit is really the best way to clean up one's own murderous energy.

Huo Hai decided that he must find a stronger soul, and whether he can no longer be disturbed by murderous aura in the future depends on this. Although this kind of murderous tempered soul may grow into a powerful helper to help him in the future, Huo Hai doesn't care. In fact, it was enough to have spirit worms, and Huo Hai really didn't care about the other helpers.

After watching it carefully a few times and making sure that he had memorized all the cultivation steps, Huo Hai carefully put away the Condensation Technique, and then continued to look at the other secret methods. The Condensation Technique was very good, but Huo Hai wanted to continue looking.

With the foundation of the Condensation Technique, when Huo Hai continued to look at other cultivation secret methods, he didn't have much burden in his heart. The result was similar to what Huo Hai thought, the other secret methods of the Blood Demon Sect were almost not very suitable.
