At this time, Zhang Yuan stood on a slippery hill and quietly watched the thunder continue to crash down, showing the majesty of heaven and earth and the boundless power. Every thunderbolt roared through the sky with boundless heat and infinite power, and Zhang Yuan had a sense of controlling the true fire in his body, and the true yuan was beating for a while. As Shenwu pulled the Yuan Force, there was a huge roar, and his dantian was even more drummed, which made his dantian feel a faint pain.

The night of thunder is a taboo for ordinary cultivators, and the powerful power of heaven and earth thunder is extremely fearful even for cultivators and demon cultivators. But for Zhang Yuan, who is pure fire, the days full of thunder are a good opportunity for him to break through. Zhang Yuan's comprehension is extremely powerful, and he can use the thunder of the outside world to attract the true yuan in his body, which makes his true yuan lively like a ball of vigorous flames, sweeping through his body. In particular, he observed the power of the thunder of heaven and earth, and could also comprehend some wonderful spells and mysteries.

Taking a long breath, Zhang Yuan suddenly sat cross-legged on a huge rock. In his arms, he was holding a medium-grade fire spirit stone the size of a fist polished to a fine light. This is also the reward he got after winning the big competition in the door, the high-grade fire spirit stone, containing a powerful fire aura, Zhang Yuan used a secret method to absorb the inner aura, a continuous and extremely thick heat, suddenly gushed out from the spirit stone, integrated into Zhang Yuan's body. The fire in Zhang Yuan's body was drumming, and a trace of heat continued to spread from his body to the outside of the body, and before the heavy rain could get close to his body, it was evaporated by the heat, and a circle of steam enveloped Zhang Yuan's body, and the water vapor within a radius of several meters was hazy.

A circle of glowing red light emitted from the spirit stone, and the red light was like a living thing, twisting and covering Zhang Yuan's body, enveloping him entirely.

Dozens of meters away, the figure flashed, and several elders of the Hundred Herb Sect, such as the Hundred Grass Dao people and the Spirit Grass Dao people, showed their figures from the rain curtain. Baicao Dao people looked at Zhang Yuan with great appreciation, nodded and exclaimed: "Good boy, you can actually comprehend the change of true fire from the thunder in the sky, and you are really a good child." It's just that Senior Brother Yuncao and Senior Sister Huicao taught him? Practicing outside the mountain protection array, he didn't take precautions at all? As soon as the tone of his voice changed, the Baicao Daoist suddenly smiled: "What a spectacular majesty of heaven and earth!" ”

Several elders of the Lingcao Daoist raised their heads at the same time, looking at the thunder that crossed the sky, and the Lingcao Daoist sighed loudly: "It's really a strange scene!" We are in the Valley of Hundred Grasses, but we haven't seen thunder in many years! The Baicao Daoist said with some remorse: "I knew that this kid was so good, I should have personally accepted him as my disciple." ”

A few old Daoists crooked their eyes and glanced at the Baicao Dao people, you could see that this Zhang Yuan Root Bone was very good, but because of the full fire attribute to give up his qualifications, he was able to quench the fire and save labor and effort, and felt that Zhang Yuan quenched every day, even if there was a spiritual root, it was impossible to make any improvement in cultivation, so he casually threw it to others as an apprentice. As a result, this Zhang Yuan was purely demonic, cultivating Dao techniques in quenching, and the speed of cultivation was rare in the world. Now that I regret it, why did I go earlier? Lingcao Daoist lowered his head and said slowly: "Senior brother, you are blushing when you see that your junior sister has benefited." ”

Baicao Daoren was stunned for a moment, patted his forehead vigorously, and scolded in a low voice: "I'm just sorry for my talent, this time my junior sister cheated and got the best talisman fairy clothes, didn't I see that all the senior brothers were embarrassed to fight with her, and deliberately instructed the disciples not to refine too good pills?" Otherwise, there are still a few good hands among the disciples in Tsing Yi, how could they refine a few different pills? ”

The Lingcao Daoist snorted coldly, and glared at the Baicao Daoist angrily: "The best talisman fairy clothes, that is clearly the magic clothes worn by women!" Senior brother, you take it out to make a lottery, how can we be embarrassed to fight? ”

"Huh? Really? Is that a woman's vestment? Baicao Daoist was silent for a while, and coughed softly: "This, it's an accident!" Isn't it true that there aren't many good things in the warehouse? That's all I can do. ”

"Hey!" The Baicao Dao people immediately changed the topic and said: "Half a year, the eighth layer of the Five Fire Recipes!" The big competition of the disciples actually refined the high-grade and low-grade fire poison pill! This little one! Let's get out of the way with me, don't get hurt on this little guy. Elder Yigan also glanced at Zhang Yuan a few times, just like the Baicao Dao people, and shook his head at the same time, everyone took out a few talismans, laid out a defensive formation, and prepared to turn around and leave.

That's when the mutation took place. In the sky, a huge thunder that crossed the void, tens of thousands of miles long, suddenly swept by, and at the junction of heaven and earth in the distance, a dazzling ball of light suddenly lit up. The Baicao Daoist exclaimed: "Heavenly Thunder Demon Punishment? What kind of monster can cause great changes in the heavens and the earth? This, this ...... "A huge heavenly thunder swept through the void, and large chunks of thunder and fire branches 'crackled' and fell, and the sky was full of dazzling purple lightning and thunder fire.

This extremely fast and incomparable Pure Yang Heavenly Thunder almost broke through all the spiritual energy in the heavens and the earth, and even the Great Mountain Protection Array of the Hundred Grass Valley could not isolate the huge oscillation caused by this heavenly thunder to the spiritual energy. Countless disciples who were doing their homework in the Baicao Valley only felt that the aura around their bodies was suddenly disordered, and all kinds of mixed aura were gushing in and out of their bodies in a chaotic manner, and hundreds of disciples who couldn't control their internal breath spurted blood on the spot and fell to the ground, but they all suffered a lot of internal injuries.

Zhang Yuan was more disturbed. The thunder almost crossed his head, and the loud sound made his heart tremble, and he almost lost his breath. Fortunately, he had the magical lotus seed replenishment root, and his mind was extremely stable, and he forcibly controlled the flow of true yuan in his body. But the thunder swept through the sky, and the surrounding aura was as chaotic as hundreds of tornadoes swept through, which involved the true fire and true yuan in his body tumbling indiscriminately, and it surged to the meridians around his body completely uncontrollably.

'Wow', Zhang Yuan spurted out a mouthful of blood, and there was a trace of red flames in the blood water. He opened his eyes in horror, just in time to see the tail of the giant heavenly thunder sweeping over his head, and a branch of thunder and fire the size of a water tank was roaring and smashing down on his head. Zhang Yuan looked at the thunder fire branch that was getting closer and closer, and was so frightened that he screamed loudly: "My life is over!" ”

A gust of wind rose in the flat ground, and a green dragon wrapped in a wind more than ten meters thick rose into the sky. A soft sound came, and the eight-foot-tall Vermilion Bird brought dozens of meters of red true fire and also soared. The Wind Dragon Firebird circled in the air for a while, condensing into a thick blue and red two-color energy, and with an amazing sound of wind and fire, it greeted the thunder and fire branch.

The Baicao Dao people turned around sharply, and suddenly saw that the thunder fire branch entangled with purple electric heavenly fire smashed into Zhang Yuan's head, and they couldn't help but be frightened, and shouted at the same time: "It's not good!" "Several old Taoists waved their big sleeves at the same time, and they didn't have time to chant the mantra, but with a mouthful of pure true yuan, they danced their big sleeves like a windmill, and set off an iron plate-like wind that swept towards the thunder and fire branch. Huzz', several elders of the Hundred Herb Sect joined forces, and an invisible and colorless wind swooped out, leveling the ground by a full three inches, and rushing towards the sky with countless dust.

The Blue Dragon Vermilion Bird transformed by the previous Fu Formation was the first to meet the thunder and fire branch, and with a loud bang, the thunder and fire branch that was already violent and unstable in nature exploded into a sky full of sparks. Each spark was like an arrow shot from a crossbow, whistling towards the ground, but it happened to meet the sleeve wind shot by a few people from Baicao Dao.

There was a loud bang, and hundreds of gossip purple gold flames flew into the sky like scattered fireflies. However, there was a flame about the size of a fist, which skillfully and skillfully drilled through a wisp of hole in the wind of the Baicao Dao people's sleeves, and just stuck to Zhang Yuan's palm. With a 'bang', like boiling fried pigskin, Zhang Yuan's left hand immediately turned purple, and a purple gold fire that made Zhang Yuan's soul tremble rushed into Zhang Yuan's body.

Purple Thunder Heavenly Fire, this is the purest masculine flame between heaven and earth, only when there are demons in the world that are not tolerated by heaven and earth, will the purple thunder heavenly fire be naturally generated by heaven and earth, and demons will be eliminated. The mung bean-sized heavenly fire stuck to Zhang Yuan's palm contained enough firepower to burn a mountain to ashes.
