Purple flames surged, almost burning the surrounding area of tens of meters into a white expanse. Ji Youfei felt wave after wave of continuous attacks transmitted from the sea of consciousness, and the North Dipper Sword Maru seemed to be exploding one by one in front of his eyes. Until the seventh wave arrived, he finally couldn't bear it, and a mouthful of blood spurted out. He shouted: "He has refined the Xuanji Dan into his body, just like a great demon possessing him! We are not his match, hurry up and retreat!"

  Apart from Mo Zi Chen being somewhat bewildered, the other two people couldn't help but be shocked and amazed upon hearing Ji You Fei's words.

  To know that human cultivators and demon cultivators have a natural barrier due to their different meridian bones, making it extremely difficult for each other's cultivation methods to be universally applicable. From ancient times to the present, there have been cases of demonic beasts who have joined human sects, but never has there been a case of a human cultivator being able to cultivate demon arts and achieve great success through the use of demon pellets.

  Before him, this Taoist priest had clearly reached the stage of building a solid foundation and was at the stage of fake Dan where the golden elixir had not yet condensed. He had already refined the Xuanji Dan and erased the divine soul imprint that was naturally born on top of the Xuan Yue purple crab. Next, as long as he could refine the Xuanji Dan again in the dantian qihai, he would be able to use this to form the golden elixir.

  Of course, this also has its drawbacks, that is, borrowing the Yao Dan to condense the Jin Dan means that in the future, he can only follow the path of demonic cultivation and will never be able to condense into a Yuan Ying.

  In the mortal world, demonic beasts are divided into nine levels according to the standards of the Immortal Realm. They must go through three great calamities. When a demonic beast is first formed, it undergoes the Dan Fire Calamity. After passing this calamity, it can form a demonic core and transform its body, becoming a demon among beasts. At the third level, there is the Transformation Calamity, which transforms the horizontal bone on top of the head, allowing it to take human form and speak human language. Reaching the fourth level makes it almost equivalent to a Golden Core cultivator in the human world. Later, there is the Bone Refining Calamity, which refines the blood vessels throughout the body, transforming its body again and unleashing the divine abilities inherited from ancient times within its blood vessels. At this level, it becomes an extremely powerful demon that can fly through the skies and traverse the earth with ease. In the human world, only a cultivator who has formed a Golden Core and achieved spiritual enlightenment can match it. After cultivating to the ninth level, one can eliminate the last bit of demonic soul within their body, greatly increasing their lifespan and even ascending to the Spiritual Realm. However, in recent years, there have been very few cases of demonic beasts reaching this level.

  This nine-thousand-year-old Xuan Yue Purple Toad King was at the stage of refining his bones when he was killed by the cultivators of Jiuhua Sect. He was almost a half-step Great Demon. The Xuanji Dan on his body naturally had extraordinary power. This Taoist priest obviously had a unique cultivation method, allowing him to merge the demon dan into his own body. With the power of the demon dan, he used the divine ability of the demon beast, and a burst of purple flames spewed out. Ji Youfei and others were not yet at the Golden Dan stage, so they were naturally unable to resist. His Beidou Sword Maru was first broken through. Then, Yu Wei's Vajra Talisman was also incinerated by the fierce fire, turning into flying ash. The flames spread across the sky, engulfing everything, and this ancient temple was almost reduced to ashes.

  At this time, Ji Xue suddenly pointed behind them and exclaimed: "Look, what is that!"

  The light in the eyes of the four people, at this time also saw that, in the place where the originally illusory great hall was located, the illusion broke and the true appearance revealed was actually a huge pit.

  In the center of the large pit, there is a stone railing carved by Han Baiyu. At each corner, there are fierce beasts such as Pixiu, Qilin and lions guarding it. A winding corridor leads directly to the underground, deep and dark, with no visible bottom.

  Judging from its shape and structure, it looked like an ancient tomb. At this moment, everyone's mind couldn't help but recall that legend.

  Ancient battlefield remains?

  In tens of thousands of years ago, the Immortal Realm had a great calamity, and it was after that great calamity that the number of people in the Immortal Realm gradually dwindled. In recent years, it has been extremely rare to hear about anyone ascending to the Spirit Realm. As for Lingshan Mountain, legend has it that it is one of the ancient battlefields left behind after that great calamity.

  It's just such a legend, almost everywhere, not only on the Kunwu continent, but also in the other eight states, it's not uncommon, so when the four of them heard it, they all just took it as a joke and didn't take it seriously.

  But what was presented in front of me was indeed a real ancient tomb.

  It was hidden deep within the highest peak of Lingjing Mountain, shrouded by the Moonlight Illusion Technique, until today, when it was finally broken through by the combined efforts of Xuanji Dan and Beidou Jianqi.

  Ji Youfeng suddenly had an epiphany and finally understood why the Taoist would have murderous intentions towards them as soon as they met.

  It's clear that he had already detected the existence of the ancient tomb, and was just waiting for the complete refinement of the Xuanji Dan to have the ability to open it. Such a great opportunity, he obviously didn't want to share with outsiders.

  It was only then that he remembered why he hadn't heard any news from the people who had received the summons before him. Perhaps they were all killed by the Taoist priest.

  The scattered cultivators are biased, and for the sake of cultivation, they will stop at nothing. The Taoist has lived for nearly five hundred years, and his lifespan is approaching its end, so he can resort to any ruthless means.

  Today is already a matter of life and death!

  The fierce flames rolled in, forcing them to retreat constantly. The three people's magic treasures had all been broken, and the Taoist priest sneered: "Four little juniors, you really don't know your own strength!"

  He has been through many things in the jianghu, his eyes are very poisonous. This brief fight has already revealed that among the four people, the most formidable one is that Ji Youfei. The other two, one has shallow experience and the other's cultivation is insufficient, they are not to be feared. Only that girl who has not made a move, her true strength is somewhat hard to discern.

  However, at this time, he had already taken a strong lead and did not expect them to come up with any tricks.

  He had just refined the Xuanji Dan and couldn't recklessly absorb the demonic energy inside, urging the spell to release another strike. Ji Youfei spat out a mouthful of blood and flew backward, and the one standing at the very front surprisingly became Mo Zichen.

  The Taoist let out a loud roar, his skin puffed up like a bellows, and he looked just like a giant toad. He opened his mouth, took a deep breath, and flames shot out in all directions, surrounding the four people in the center.

  At this time, Yu Wei had already taken out the last talisman, the Divine Movement Talisman. The wonderful use of this talisman was to instantly transport the holder a hundred miles away. If he had escaped at the beginning of the battle, he would have had a great chance of success, but now that his foundation was not yet established and his magical powers were still shallow, it was extremely difficult for him to bring four people with him.

  But even so, he did not abandon everyone and escape. Instead, in the end, he resorted to this extremely slim chance of a move.

  The purple flames had already enveloped Mo Zi Chen's body, and she stood there stupidly, as if stunned, without any intention of dodging.

  I haven't even joined the immortal sect yet, am I supposed to die here? That cheap master of mine, you didn't teach me any magic at all, are you trying to get me killed?!

  A fierce flame was approaching, the Taoist let out a triumphant and crazy laugh, but no one saw that Mo Zi Chen's jade pendant on her chest was shining with soft light at this time. The fierce flames passed over Mo Zi Chen's body, but did not hurt her in any way, instead being swallowed by it one by one.
