At the moment when Ah Hao waved the devil's divine knife, this sentence drilled into Ah Hao's mind without warning. Looking at the blade that was about to swing, Ah Hao didn't know how many times he had seen this scene, countless times he had fought against people, Ah Hao suppressed the other party with the powerful strength of the Devil Divine Knife itself, but this situation has been able to feel obvious deficiencies with Ah Hao's improvement.

"How do you connect the Underworld Technique with the Devil's Divine Sword!" this question first surfaced in Hao's mind.

"Poof!" The black spear would not stop because of Ah Hao's pause, and the huge impact of the spear did not block it, but directly penetrated from Ah Hao's chest, and the pain in his body made Ah Hao's expression change.

The body couldn't stop retreating, but the ghost still had no intention of giving up after the first blow. The spear was returned to his hand, and the ghost still reluctantly lifted the spear and rushed towards Ah Hao, as if it must kill the latter.

Seeing another circle of black dead qi wrapped around this spear, Ah Hao's eyes suddenly lit up.

"The reason why the Devil's Divine Sword and the Underworld are not combined with each other is because the method is wrong. They use this method to connect the weapons in their hands with themselves, and the Devil Divine Sword is not an ordinary divine weapon, so naturally there are different methods. When you think about it, it seems more reasonable.

The blade stood in front of him, and the underworld was running wildly in Ah Hao's body, and Ah Hao used the underworld to suck the dead qi in the underworld, which allowed him to control the devil's divine knife through his mind, which was impossible before, so the problem should be in this dead air.

The operation of the dark spell caused the dead qi around the air to gather in large quantities as if it had touched a whirlpool, centered on Ah Hao. With the gathering of dead air, Ah Hao seemed to be able to feel the devil's divine knife at a certain moment.

"It really works!" Ah Hao said secretly, his eyes looked at the black spear in front of him, Ah Hao reached out and grabbed it, and the devil knife suspended in front of Ah Hao fell into Ah Hao's hand. The same slash fell, but this time, before the blade arrived, the chill that rolled in front of the blade had already slashed the black spear to pieces. When the blade fell, the masked ghost disappeared under the knife without even making a sound.

Looking at the swing of the knife with some joy, Ah Hao looked at the devil magic knife in his hand, but this time, he didn't feel like last time. His brows furrowed together, "Can you only rely on death qi to connect the underworld and the devil's divine sword?" However, it is okay in the underworld, but what about going to the human world?" This question made Ah Hao, who was overjoyed, seem to have been poured with cold water, and instantly regained his calm.

The area of the battlefield of the undead is more than that of the drunken shade, and when he was tired, Ah Hao found a place to rest, because this place is too big, so it is impossible to have ghost soldiers in every place, the more he goes to the back, the more scattered the ghost soldiers are, and the last time he encountered the situation, Ah Hao has also encountered one or two times after that, and he never understood how this ghost thing that is different from the ghost soldiers found himself.

Sitting down against the stone wall, Ah Hao stroked the devil knife in his hand. Since this battle, Ah Hao has been thinking about this problem, he once thought about carrying the death qi in his body, but this method was quickly abandoned by Ah Hao, if he goes to the human world, the death qi will always run out, does Ah Hao have to run back to the underworld to get it again!

"Death Qi has become a medium between the Devil's Divine Sword and the Underworld, so is there anything else that can replace it. Hao thought so. Time passed little by little in Hao's thoughts, but he still had no clue.

"He, how did he do it?" At this time, Ah Hao suddenly remembered the Hades, he is a human being, because when he came to the underworld, death is an important reason why it is not difficult for humans to stay here for a long time, so he created the Underworld, and then how did he connect the Devil's Divine Sword with the Underworld...

With this in mind, Hao let the magic work in his body again. And his mind moved along with the operation of this dark art. Ah Hao looked at the trajectory of the dark art in his body, since the dark art was created because of the death air, then the dark art and the death air must have a certain connection, I didn't find it before, but I didn't find it, now that I have time, and with Ah Hao's deeper and deeper understanding of the dark art, Ah Hao firmly believes that the Hades King at that time should have done just that.

Sitting under this protruding stone wall, the stones above my head seemed to fall at any moment. And Ah Hao's mind has been flowing with the flow of the underworld since he sat down, and the strange thing is that during this period of time, there were no ghost soldiers to disturb him, and the place where Ah Hao sat was not very hidden, although it was not conspicuous, but as long as you pay attention, you can still see it. The magic of the underworld kept circulating in Ah Hao's body, round and round, the first time, Ah Hao didn't see anything, the second time, Ah Hao still didn't find anything, the third time, it was still like this, the fourth time。。。。。。 Even Ah Hao couldn't count how many times the magic had been running in his body, and suddenly, Hao, who was already numb, found that something seemed to be brought out in his body along with the operation of the magic in the process of running the magic technique.

With this discovery, Ah Hao raised his motivation again, and carefully stared at the thing that rotated with the Immortal Technique, this substance was not dead air, but it had a similar place to dead air.

"Could it be! Hades used this to make a connection between the Underworld and the Devil's Divine Sword. With this thought, Ah Hao immediately pulled out this kind of thing from the operation of the underworld. Although there are very few, at least this kind of thing will accumulate in Ah Hao's body with the operation of the underworld, and it can be regarded as a self-made thing, and it can be used at critical moments, no matter how it is said, it is much better than the death of the outside world.

The dark art continues to run non-stop, and every time it runs, Ah Hao will deliberately leave this substance, Ah Hao didn't care about it before, so he didn't find this kind of thing at all, and now Ah Hao's grasp of the dark art is still very superficial, so the speed of the dark art in Ah Hao's body is not fast, if Ah Hao is proficient in the dark art to a very powerful point, he doesn't need to work hard to accumulate this thing.

When there were enough of these accumulated things, Ah Hao tried to let this substance flow into the Devil's Divine Knife...

For a long time, there was no movement, the Devil Divine Knife was still so quiet that there was no reaction in Ah Hao's hand, just when Ah Hao was about to give up, suddenly, Ah Hao saw that the handle of the Devil Divine Knife seemed to light up, and it was fleeting, and it was almost so fast that Ah Hao himself had a hallucination.

However, Ah Hao was sure that he was not wrong just now, and with this situation, Ah Hao continued to input this kind of thing into the devil's divine knife.

"Hum!" As there are more and more such things, the Devil Divine Knife emits a violent vibration, and as the sound sounds, a black and blue light curtain erupts from the Devil Divine Knife's knife body, and the black and blue swept out, as if the vast ocean poured into this undead battlefield, a black and blue light curtain quickly spread from Ah Hao's location to the entire undead battlefield...
