As Mu Bai approached the place where everyone was fighting, the people present were fighting hard, and they didn't attract much attention from others. As he got closer, Mu Bai walked around as he took out a handful of blank runes from the storage bag, bit his fingers, and kept carving blood-colored runes on them.

With the continuous carving, the blood continues to merge into the blank runes, and the runes are made in the blink of an eye.

The downside is that the sigil can't be preserved for a long time, but at a cost of ...... His cultivation, as the rune was formed, was gradually decreasing, and even his hair was becoming a little gray, and he stopped when his cultivation fell to the eighth level of the spirit induction, only one step away.

And the blood cultivation sigils, there are hundreds of them, suspended in front of him, but these sigils are not used for attack, but for defense. Let hundreds of runes form a defensive formation, cross a large realm in a short period of time, and have the defense of the Great Perfection of Soul Building.

Because he knew that if it was used to attack, at most he would have a full force blow of the Great Perfection of Soul Building, but this full force blow would be far from enough. But if it is used for defense, it can drag the humanoid demon beast on the opposite side for a while and a half, but the price is unbearable for him.

Looking at these runes that were vaguely related to himself, Mu Bai's expression gradually turned cold, he no longer hesitated, and with a wave of his hand, hundreds of runes were all thrown towards the two sides fighting in the field.

Looking at the throwing of the rune, Mu Bai's right index finger swallowed the spiritual power, crossed the palm of his left hand, and a piece of blood gushed out of cultivation, and the seal of his right hand, the blood gushing out of the gushing out instantly condensed into a blood ball, and the blood cell divided into hundreds of blood-colored fine silk threads, extending to the throwing rune, and in an instant, the blood ball and the rune were connected together.

The index finger of his right hand pointed at the blood cell, and those sigils were arranged in an orderly manner according to the array, falling in the middle of the two sides in the field, and shattered instantly.

After the blood cultivation talisman seal shattered, one by one the blood-colored talisman appeared, connecting those tiny silk threads, emitting bloody light, forming a blood-colored protective shield, enveloping all the disciples and elders in the field, and in the blink of an eye, they blocked both sides.

The disciples and elders of the various sects originally didn't pay too much attention to Mu Bai, but as Mu Bai cultivated his own blood, he made more than 100 runes on the spot, and the subsequent scenes, until the shield was formed, everything was seen in their eyes, and they all showed shock.

The blood cultivation talisman belongs to the forbidden technique of the rune spirit master, but the price is too great, and they know very well what the price of the rune spirit master is for using the blood cultivation rune seal.

Seeing this, all the humanoid demon beasts were also slightly stunned, and without the order of the tall humanoid demon beasts, they did not hesitate to attack the blood-colored shield frantically. With the crazy attack of the humanoid demon beast, every time he attacked, Mu Bai's face turned a little pale, his hair would be grayer, and his cultivation breath would be weaker.

Elder Fu Tian of the Yuqing Sect glanced at Mu Bai deeply, as if he wanted to remember him, took a deep breath, and no longer paid attention to the demon beast opposite, but his expression was gloomy, and he suddenly shouted, waking up everyone present, "All the elders and disciples, do your best to export spiritual power and fuse the last demon soul essence. Once successful, it will be the death of the other party!"

Hearing Fu Tian's shouting, everyone did not hesitate, put away the magic weapon, completely ignored the side, encouraged the spiritual power of the whole body, brought up the clothes and swayed, from the dantian, the spiritual power continued to flow through the meridians, surging into the palm, and instilling it towards the golden altar in mid-air.

The red light in the eyes of the tall humanoid demon beast flickered wildly, and he waved his big hand violently, "All the demon warriors obey the order, in order to speed up, for the plan of the Black Law Lord, the time has come for you to dedicate yourself to the Black Law Lord, rush!"

After the order of the tall humanoid demon beast fell, all the humanoid demon beasts suddenly went crazy, their expressions were hideous, and they rushed towards the blood-colored light mask regardless of life and death, and in the process of impact, the meridians of the whole body reversed, and there was a humanoid demon beast first, spurting blood from its mouth, and slammed into the light curtain.

With a deafening, earth-shattering roar came out, and the demon beast exploded itself as it crashed into the light mask...... And the red light mask, with the self-explosion of the demon beast, fluctuated violently, and seemed to be about to burst at any time.

Mu Bai's complexion changed slightly, he suddenly raised his right palm, and slapped it at his heart without hesitation, and immediately a piece of heart and mouth essence blood spurted out of his mouth, turned into a blood arrow, and shot towards the blood ball in front of him, as his heart and mouth essence blood merged, the blood ball instantly became twice as large.

Immediately after, wisps of essence blood passed through the thin thread and passed to the blood-colored protective shield. And the protective light shield that absorbed the essence of blood, the blood was even better, and the violent fluctuations gradually stabilized, and finally stood quietly in the field, protecting everyone.

And his cultivation breath also fell to the eighth layer of the spirit attraction with the spurt of this mouthful of essence blood, but even the cultivation of these eight layers was extremely unstable, and it seemed that he would fall towards the seventh layer at any time, and his hair became gray because of this, and gradually changed to snow white.

And all the people of the various sects in the field, seeing Mu Bai's crazy approach, they also went completely crazy, and at all costs, they frantically urged the spiritual power in their bodies, risking the risk of their cultivation falling, overdrawing their origins, and instilling spiritual power into the golden altar.

On the other side of the light curtain, the sound of the self-explosion of the humanoid demon beast at this time kept ringing, and every time it sounded, the fluctuation of the shield would be more violent. And the blood cells that were constantly flowing towards the shield also became smaller at this time.

In less than a moment, after a humanoid demon beast in the early stage of spirit building exploded, the shield suddenly broke through a fist-sized hole, but at this time, the hole was constantly healing.

But immediately after, the sound of two demon beasts in the early stage of spirit building sounded, and the fist-sized hole suddenly expanded with the power of self-explosion, instantly breaking a large hole that could accommodate one person in and out.

And Mu Bai inside the shield, with the appearance of this big hole, the blood ball in front of him was completely consumed, and the blood-colored defensive shield also completely collapsed, turning into nothingness.

Seeing that the shield disappeared, all the people of the sect were a little pale, and the tall humanoid demon beast was excited, leading his subordinates to rush to everyone first, and when he passed by Mu Bai, with a wave of his hand, he waved Mu Bai, who had cultivated to a big fall, vomited blood and flew upside down, rolling and falling a few zhang away.

The tall humanoid demon beast didn't even look at him, he was in a hurry at the moment, before the golden altar completed its absorption, he led his subordinates to interrupt all the people who were instilling spiritual power into the golden altar.

Leading its subordinates, it looked at the golden altar in mid-air, its expression became more and more anxious, and it frantically attacked the people around it.
