Ghost Doctor Xue stared, the whole person was stunned, and just wanted to say something, at this time, Lao Liu Tou suddenly put the purple talisman in his hand on the seven-star Longyuan sword, and quickly pinched a few fingers, the purple rune, "poof" was blazing, not only the purple rune was burning, but also the seven-star Longyuan sword, with a bang, followed by a purple flame, Wu Feng ate two ancestral grandfather's pills in a row, The seven-star Longyuan sword only glowed with a purple bright light, but Lao Liutou's purple rune made the seven-star Longyuan sword burn, and it was worthy of the purple rune drawn by the world-famous rune three uniques, which actually stimulated the potential great power of this seven-star Longyuan sword.

This kind of talisman takes a lot of effort, and it takes three or five years to draw such a powerful talisman, and some even take longer, and the power contained in it should not be underestimated.

The seven-star Longyuan sword was completely ignited, the buzzing sound was loud, the purple flame wrapped the old Liu Tou in a mysterious atmosphere, and the surrounding area was transparent, looking at the sword in his hand, the old Liu Tou laughed, and praised again in his mouth: "Good sword!" It's really a peerless sword, you can help the old man, let's kill this thousand-year-old blood demon together, and restore peace in the world! ”

"Roaring ......"

The sword seemed to understand Lao Liu Tou's words, and suddenly let out a desolate and majestic dragon roar, which made people's hearts tremble, and even Lao Liu Tou was startled.

However, Lao Liu Tou quickly calmed down, a resolute look appeared on his face, he turned his head to look at Ghost Doctor Xue and Wu Feng, and said solemnly: "Old man Xue, the old man will go first, you take care of that kid Wu Feng!" ”

After that, Lao Liu Tou raised the Seven-Star Longyuan Sword in his hand, and at this moment, Lao Liu Tou's figure suddenly became extremely tall in the eyes of everyone, and Ghost Doctor Xue felt a kind of momentum from his body, and at the same time, he had a very bad premonition in his heart.

Ghost Doctor Xue was about to say something, but was interrupted by the sound of Old Liu's spell.

But seeing that Lao Liu Tou pointed at the sky, he shouted majestically and solemnly in his mouth: "Nine Heavens Xuanlei, lead it with a sword, Huanghuang Tianwei, thunder axe is not tolerated, I use my blood body, turn it into a powerful spell, kill demons, and save the common people......"

With the sound of Lao Liu's incantation, all of a sudden, the wind was raging, the mountains and forests were howling, and above the sky, dark clouds were thick, lightning and thunder were roaring, with Lao Liu Tou as the center, and an invisible gang qi spread out to the surroundings.

Ghost Doctor Xue heard the sound of Lao Liu's spell, and then he understood, it turned out that Lao Liu Tou wanted to use his life to combine with that talisman to trigger the Nine Heavens Xuanlei and kill the thousand-year-old blood demon, this is a very powerful spell, even if it is a top master in the rivers and lakes, such as the head of Maoshan and the like, he does not dare to use such a big spell lightly, this is simply going against the sky, it will inevitably lead to fire, no matter how high your cultivation is, you will be subject to a huge backlash, nine out of ten will not survive, Not to mention that Lao Liu Tou is such a humble cultivator, there is no difference between sending him to death.

If it weren't for the purple talisman that Old Liu Tou took out, it would have been impossible to trigger the Nine Heavens Xuan Thunder.
