The size of the Demon Slayer Seal can be freely controlled with Lu He's mind, as large as a mountain, or as small as a fingernail.

And now, the Demon Destroying Seal in Lu He's hand is the size of a thumbnail, the Demon Destroying Seal is boxy, the top is a horizontal long sword statue, and the lower base is engraved with two big characters of Demon Destroying.

Lu He didn't have time to carefully study the Demon Slayer Seal at this time, he just held the Demon Slaying Mark in his hand, then took a deep breath, and slowly walked towards the prohibition in front of him.

At this time, Lu He's body was only the size of a peanut, and this Demon Destroying Seal also became smaller with the changes in Lu He's body, and it was a treasure that could communicate with Lu He's mind like the Xuanbing Sword.

Although it is said that this is the best spiritual weapon exchanged in the Treasure Pavilion, it is not clear whether it is useful or not, so when he touched the prohibition, Lu He's heart was still quite nervous.

The lilac prohibition was like a faint air at this time, and Lu He's body was not hindered in the slightest, so he passed through the prohibition directly and came to a stone gate.

This stone gate is very tall, about thirty meters high, and the construction is very rough, there is an adult finger thick ground clearance below, Lu He's body at this time is like peanuts, so he walked directly into the gap under the stone door, but it saved the trouble of opening the door.

Passing through the stone gate, Lu He's heart was secretly glad that this size Ruyi was really a good supernatural power, and today, if it weren't for the big and small Ruyi supernatural powers, then Lu He would have passed the ban with the Demon Slaying Seal, but looking at the stone gate in front of him, he could only look at the door and sigh, because if he opened the door, he would definitely alarm the Blood Demon Venerable inside.

The size of the wishful supernatural powers, the transformation of the body and the transformation of the supernatural powers, the demon destroying seal, the jade plate, the invisibility charm.

These five things are indispensable, and without any of them, it is impossible for Lu He to easily blend into this stone gate.

At this time, there was a huge stone room in front of Lu He's eyes in the stone gate, and in the center of the stone room, there was a huge jade bed, which exuded a faint fluorescence, which obviously had a healing effect.

And on the jade bed, a majestic figure was sitting cross-legged in it.

Blood Demon Venerable!

What the Blood Demon Venerable presented to Lu He at this time was his main body, which was like a human race, with a green face and fangs, and a pair of fleshy wings on his back.

At this time, the Blood Demon Venerable's eyes were closed, a pair of fangs poked out of his lips, and between breaths, the sound of whirring wind sounded in the stone room.

Lu He held his breath and stared, standing motionless, just quietly observing the Blood Demon Venerable.

The Blood Demon Venerable's body is more than ten meters tall, which may also be the height he deliberately controls in order to adapt to the size of this stone room, if it is outside, his body will only be even larger.

And the Blood Demon Venerable's pair of blood-red claws were placed on his knees, and there were two blood-red light clusters on top of the claws, and the dark red blood mist in the light clusters was entering his nose with his breathing.

It was clear that the Blood Demon Venerable was healing right now.

Lu He's heart was beating fast, this can't be blamed for his poor psychological quality, it is really that the breath and coercion on this Blood Demon Venerable are too terrifying, the breath of the Purple Mansion Realm is perfect, even if Lu He's current strength can compete with the high-level monks of the Purple Mansion Realm, but when he encounters a strong man like the Blood Demon Venerable who has been in the world for thousands of years, he still has no power to fight back.

Even, because of nervousness, Lu He felt that his legs were a little weak at this time, and his arms were a little stiff.

Of course, this was completely different from the situation when Lu He first saw the Black Dragon Holy Lord, when Lu He saw the Black Dragon Lord at that time, he was so frightened that he stiffened and didn't dare to move.

Lu He quietly observed the time of approaching a stick of incense, and determined that this Blood Demon Venerable was using his spiritual sense to heal his injuries, and then he slowly breathed a sigh of relief.

But Lu He didn't spit out this breath of relief, he hadn't breathed since he entered this stone room, just because he was worried that because of his breathing, there would be an unusual breeze in this stone room, and a strong person like the Blood Demon Venerable was very sensitive to the changes in the breath and air around him, and it was easy for the Blood Demon Venerable to find out.

In short, for a monk like him, not breathing for a period of time had no effect.

The time for a stick of incense had come, Lu He no longer hesitated, slowly took out his Xuanbing Sword, and then slowly floated towards the Blood Demon Venerable.

Yes, Lu He is floating, and he uses the power of the Tao to support his legs.

In order to be afraid that his speed would be too fast and the wind and waves would be excited, Lu He took half a pillar of incense to move forward a hundred meters.

At this time, he was less than a hundred meters away from the Blood Demon Venerable.

At a distance of 100 meters, the fourth-order madness supernatural power can exert a strong effect.

Of course, this kind of attack effect is only to use qi, use the power of sword qi and Dao to hurt the Blood Demon Venerable, if the distance between Lu He and the Blood Demon Venerable is close enough, and use the Xuanbing Sword itself to cut the Blood Demon Venerable, then it can exert the perfect effect of the fourth-order madness supernatural power.

However, the gap between the two is not very big, not to mention that if Lu He is too close to the Blood Demon Venerable, he is also worried about being detected by the Blood Demon Venerable.

Sometimes, the strong man has a premonition of a crisis in his heart, even if he himself is not aware of any crisis, but his instinct will make him feel uneasy.

But now all the minds of the Blood Demon Venerable are repairing the wounds in their bodies, and they are not as sensitive to the changes in the outside world as Lu He imagined.

In Lu He's eyes, there was not the slightest murderous aura, and it was as calm as a pool of ancient wells.

Fourth-Order Crazy Divine Power!

At this moment, a heaven-shattering sword qi slashed out from the Xuanbing Sword in Lu He's hand, slashing straight at the Blood Demon Venerable's body that was more than ten meters high.

The Blood Demon Venerable didn't react at all, and his body was split in half by Lu He in an instant.

Refreshing!

Lu He appeared, his body became more than ten meters tall like the Blood Demon Venerable, and the Xuanbing Sword in his hand also became ten meters long.

Lu He stepped out and instantly appeared in front of the Blood Demon Venerable, looking at the corpse on the ground that was split in two, and sneered: "Blood Demon Venerable, you didn't expect this day, did you?"

"Who are you!"

The Blood Demon Venerable was furious, and roared angrily: "Do you know who this seat is? You dare to sneak attack this seat, the eldest brother of this seat is the lord of the Henglan, and the master of this seat is the first earth of the demon clan, you are tired of it?"

"Hahaha!"

Lu He raised his head and laughed wildly, how happy his heart was, and the hatred for many days came out at one time, is there anything more comfortable in this world?

Without saying a word, the Xuanbing Sword in Lu He's hand slashed out dozens of swords one after another, directly breaking down the corpse of the Blood Demon Venerable into small pieces one by one.
