The blood in Gu Feiyu's body became less and less, his head became groggy again, and it was already difficult to breathe, and he clearly felt that his heartbeat was so weak as if it was about to stop.

At this moment, even Gu Feiyu himself felt a change in himself, looking at the arm looming in front of him as if it was about to disappear in the next moment, and Bai Feiyan's true qi circulation was silently broken, and his body, which had lost its strength support, lay on the grass backwards.

"Brother Feiyu!" Bai Feiyan's eyes were flustered, and he hurriedly shouted, but before he could get up, he saw that his body began to change again.

The looming body finally turned into a book in a ray of light, lying quietly on the grass without moving, and the Blood Devouring Demon Ding still didn't let him go, still absorbing the aura contained in the book.

At this moment, the book was finally no longer silent, and in an instant, the light suddenly flourished, and the two words of the Book of Heaven slowly bloomed with an incomparably dazzling light, impacting the blood-colored suppression of this heaven and earth.

Bai Feiyan looked at this scene in surprise, she finally knew the book she had been seeing from Gu Feiyu, and muttered in her mouth: "Book of Heaven! How can Brother Feiyu be a Book of Heaven?"

Under Bai Feiyan's gaze, the Book of Heaven finally began to bloom with its unparalleled power, and the two words of the Book of Heaven turned into golden light and suddenly attacked, and the pillar of light directly hit the Blood Devouring Demon Ding.

"Boom-" The huge roar shook the earth, and the two mysterious magic weapons collided together in the most brutal way, and the huge wave of spiritual energy spread to all sides, Bai Feiyan was directly knocked to the ground by this force, and an imperceptible flash of light flashed on her chest to protect her.

The old man who had been controlling the Blood Devouring Demon Ding on the side was connected to the giant Ding at the same time, and his chest slammed out a mouthful of blood, and the impact of the aura wave knocked him to the ground, looking at this scene in horror, and when he looked at the book of heaven, there was more madness and greed in his eyes.

Neither the weeds nor the trees around could withstand the impact of such a powerful force, and they fell to the ground one after another, and the huge trees were even more broken off and collapsed, but there were no birds scattered, and they had already been frightened back by the old man's gloomy and cold aura at the beginning of the battle.

After the impact, the dust settled, Bai Feiyan looked towards the two magic weapons in the air, at this moment, the blood color emitted by the Blood Devouring Demon Ding had been completely dispersed by the power of the Heavenly Book, and the feeling of the qi and blood being withdrawn from the body was gone, and the eyes looked at the Heavenly Book occupying one side, and the light at this moment was also weaker after the impact.

The old man stood up with difficulty, watching the Blood Devouring Demon Ding being suppressed by the Book of Heaven, the scarlet blood light was tumbling and boiling in and around the Ding, but it could not spread out, and the anger and impatience in his heart caused the injuries on his body, and he coughed violently.

"The Book of Heaven, it turned out to be the Book of Heaven! If I can subdue it in Yunzhou, who can help me?" the old man laughed maniacally, spitting out the essence blood in his mouth and levitating in front of him, his shriveled fingers full of wrinkles and dead skin pointed at the essence blood, waving rapidly.

As if he was writing something, but what he drew was not like words, at least Bai Feiyan couldn't understand any of them, the strokes were weird, obscure and difficult, like a ghost talisman that made people tremble in their hearts, and with the wave of his fingers, each formed symbol turned from bright red to black mist.

Immediately after that, the old man shouted, pinched the magic trick in his hand, and punched one strange text after another into the Blood Devouring Demon Ding, every time a strange text symbol was punched into the Ding's body, the old man's face was pale and weak, but he still continued wildly.

Seeing this scene, Bai Feiyan wanted to stop it but couldn't lift half of her strength because of excessive blood loss, although the body was full of true qi, but the qi and blood contained the essence of human beings could not be compensated for by true qi alone, and the existence of true qi could only barely make her hold on for a while.

As for stopping the old man, she is simply powerless at the moment, and escaping may be the best time, but how could she leave Gu Feiyu, whose life and death are unknown, and has become a book in the sky.

As time passed, the old man didn't know how many ghost runes he had injected into the ding, only to see that his body had become trembling, even standing was extremely difficult, maybe a gust of wind could blow him to the ground at this moment.

Although the Book of Heaven is mysterious and unpredictable, it suppressed the Blood Devouring Demon Ding as soon as it appeared, but it is always an ownerless thing, and its strength is always limited by instinct when no one controls it.

The Blood Devouring Demon Ding contains the old man's profound cultivation true qi in the outside world, and there is an old man controlling it on the side, how can it be so easy to suppress?

Every time the old man entered a ghost rune like the Blood Devouring Demon Ding, although he was constantly getting weaker, the Blood Devouring Demon Ding in the air was once again full of blood with the influx of ghost runes, and every movement of the old man made its blood more vigorous.

Finally, the power of the Book of Heaven could no longer suppress the blood-colored light of the crazy bloom of the Blood Devouring Demon Ding, and with a bang, the blood light emitted by the Blood Devouring Demon Ding finally broke through the suppression of the Book of Heaven and began to confront the Book of Heaven head-on.

In the sky, the scarlet blood color returned again, and the golden light of the Book of Heaven occupied half of the sky, and the two continued to impact, but no one could help anyone, and they were frozen in mid-air for a while.

Seeing this scene, Bai Feiyan quietly breathed a sigh of relief, but still nervously clenched his little hands and looked up tightly.

When the old man saw this scene, the anxiety in his eyes became even more obvious, there was not much true qi left in his body, although the series of magic tricks just now was extraordinary, but it was consuming his own essence and blood, and the essence and spirit at this time were greatly damaged, which could be described as an extremely crazy method of self-harm.

"Fight!" the old man looked at the two magic weapons that were stalemate in the sky, and said angrily. He naturally knew the power of the Blood Devouring Demon Ding, not to mention that the Demon Ding still contained his lifelong cultivation at this time, even so, just relying on the strength of the Book of Heaven itself to resist to such a point, it can be seen that the power of the Book of Heaven, in order to get the Book of Heaven, he no longer cares about the consequences.

The old man roared heartbreakingly, and suddenly a pair of cloudy eyes became red, and with a "bang", a cloud of blood mist erupted around the old man's body, and the trembling body in the blood mist kept dancing, and a strange and strange sound kept coming out of it.

With the old man's movements, it didn't take long, only a moment, the blood mist suddenly contracted in a moment, and the magic in the old man's hand pinched extremely quickly, only a piece of afterimage could be seen, with the end of the old man's last magic trick, the blood mist that shrank together suddenly pointed out, this blood mist was the vast majority of the essence blood on his body.

The blood mist boiled in an instant, and then it kept changing between tumbling and boiling in the air, and the old man's eyes that had turned into blood red stared tightly, and finally turned into a huge 'death' word, which was extremely huge and bloomed with a huge blood-colored light.

Seeing the word death take shape, the old man laughed wildly, as terrifying as a ghost crying wolf.

Immediately after that, the old man's face was hideous, his blood-red eyes bloomed with a terrifying essence, and he shouted: "Go!" suddenly slapped the huge word 'death' in front of him, and the word suddenly shook, and he rushed towards the Blood Devouring Demon Ding, and hit the giant Ding in Bai Feiyan's desperate gaze.

Bai Feiyan stood there in a daze, biting his red lip unwillingly, watching the blood words merge into the giant tripod but there was nothing he could do.

The old man had lost his last strength after doing all this, and sat down on the grass, but he was not at all disappointed, but looked at the sky with a look of great expectation, not caring about his own situation.

With the huge influx of the word 'death', the Blood Devouring Demon Ding became quiet in an instant, and even the blood light seemed to stop, and Bai Feiyan was stunned.

But before she could be happy, the Blood Devouring Demon Ding became restless again, and the scarlet qi and blood suddenly spread out from the Ding's body, even the Book of Heaven could no longer stop its expansion, and the blood color spread to the sky like a bamboo, forming an absolute suppression, with the blessing of the word of death, the Blood Devouring Demon Ding suddenly burst out with such a powerful power, even the Book of Heaven was difficult to contain.

Bai Feiyan's face changed suddenly, his heart was shocked but there was nothing he could do, the light of the Book of Heaven in the sky was too small, it could only protect the Book of Heaven itself, but how long could it last?

The blood color is even better than at the beginning, filling the world here, and the Blood Devouring Demon Ding has begun to frantically absorb all the vitality around it, and at this moment it is no longer limited to blood, Bai Feiyan was sucked blood again, and his body shook.

The Book of Heaven suddenly flashed with light, as if it wanted to fight back, but it was quickly suppressed by the Blood Devouring Demon Ding again, and the light that had just spread out was once again compressed on the Book of Heaven itself.

This scene seemed to anger the Blood Devouring Demon Ding, and it actually began to burst out with a huge suction, Tianshu staggered and barely resisted, but it was difficult to resist the powerful Demon Ding, and after a stalemate for a while, it was suddenly sucked into the Ding by the Demon Ding.

Bai Feiyan's face was gloomy, and he shouted heartbreakingly: "Don't, Brother Feiyu!" But no matter how she shouted, it was to no avail, and the Book of Heaven was still swallowed by the Demon Ding.

Bai Feiyan gritted his teeth and wanted to do something, frantically wanting to fight, but the manpower was always limited, and only the light in his chest was better.

Subsequently, perhaps sensing the situation of the book of heaven, the book on Bai Feiyan's chest finally began to manifest, Bai Feiyan's eyes flashed, and his body suddenly had endless vitality, as if he was blessed by some power, and finally burst out of his own potential under anger.

Bai Feiyan put his fingers together and sparkled at the Blood-Devouring Demon Ding in the sky, and a dazzling white light rushed to the sky, stabbing towards the giant ding like a sharp sword.
