C20 Moxibustion!

After arranging everything, Sacred Xuan leaped into the air and arrived at the mouth of the spring. Although it wasn't big, it was still okay for him to sit there.

Sacred Xuan sat cross-legged at the top of the spring, his lips moving slightly. After chanting some incantation, the mist formed by the Void Spirit Spring started to revolve around him, enveloping him completely. Sacred Xuan saw this and couldn't help but smile slightly, the effect was better than what he expected.

"The Spirit Gathering Method that Grandpa Wu Guang taught is really useful. However, perhaps the spiritual energy here is already abundant. Now that the problem of the supply of spiritual energy has been solved, the beast's inner core will be next." Then, his spiritual will stopped at the item in the storage ring that Wu Guang gave him. With a slight thought, the item appeared in front of him.

It was a pitch-black box covered with unknown ornaments. There was even a piece of yellow paper glued to the box.

Saint Xuan indifferently looked at the talisman, then remembered Wu Guang's words, "Cultivators call it a pill formation, but to put it bluntly, it is to compress the spiritual energy within the body into a purer solid. On the other hand, the body refiner cultivates elemental energy, which has nothing to do with the five elements, but is also not able to compress the spiritual energy within the five elements. Furthermore, the body refiners think of a method to condense the internal core of a demon beast.

Thinking of this, Sacred Xuan couldn't help but feel a deep admiration for the person who had created this method. In his opinion, this was simply defying the heavens, but thinking about it, cultivation was originally a method to defy the heavens.

Then, Sacred Xuan cautiously stretched out his hand to take away the talisman.

"Hiss ~ ~" The moment the symbol paper was removed, a gust of cold air blew over. Sheng Xuan felt as if he had fallen into a cave of ice, his entire body almost freezing over.

"What the hell is this inner core of a demon beast? It's actually so strong!" Sacred Xuan was shocked, but then he began to get serious again. At this critical moment, he didn't have time to think about what sort of pill this pill was; he had to refine it!

Sheng Xuan didn't dare to hesitate. With a serious expression, he took out his purple eyes and carefully observed the change in the box. He opened the box with all his might, and a black light shot out from it, blurring Sheng Xuan's vision. But when he saw what was inside, his face filled with shock.

Inside the opened box lay a black pearl. A black dragon's shadow coiled around it, emitting waves of chilliness. But, rather than calling it chilliness, it was more sinister. This was because the Sacred Xuan could sense the danger from the beast core.

"This is the Demon Dragon Pill!" There was still a shocked expression on Sacred Xuan's face. After all, this was the first time he had seen the dragon clan's inner core since he was born.

"But why is there evil energy inside this pellet?" Sacred Xuan felt a faint resistance in his heart. He knew that this was because the purple pupils were the purest of objects, and he was naturally resistant to this sort of evil charm.

However, he still stretched out his hand to grab the dragon core. As soon as he held it in his hand, he felt a bone-piercing chill invade Sheng Xuan's internal organs. His Diamond Protection also seemed to sense this evil intent, and without waiting for Sheng Xuan's chant, it automatically ran out to help him resist the cold.

Sheng Xuan's eyes were filled with seriousness as he stared at the pill. Gritting his teeth, he opened his mouth and swallowed the pill as Wu Guang had said.

"Ah!" As soon as the dragon core entered his body, the moment it entered his dantian, Sacred Xuan's body suddenly felt an explosive pain. It was a good thing that he had been cultivating the Diamond Protection for so many years, so he was able to resist the pain.

The dragon core was quietly suspended in Sheng Xuan's dantian. With a quick thought, he circulated the elemental energy in his body, attempting to infuse it with the dragon core. However, he was met with an obstruction from a large amount of energy.

Clenching his teeth once more, Sheng Xuan increased the infusion of elemental energy. The spiritual energy in the spirit spring surrounding him also began to rush into his body, immediately forming a ball of spiritual energy and pouring into the pill.

Sheng Xuan didn't dare to stay idle either. Clenching his hands tightly, he retracted the Diamond Protection inner strength, protecting his internal organs to prevent himself from suffering heavy injuries.

"Using the demon core as a guide, we use the spiritual Qi of Heaven and Earth to help the demon core, infuse it with Essence, and force the demon soul out to refine it." As Sacred Xuan silently recited these words, he could feel the resistance from the Dragon Core. His eyes suddenly turned purple.

"Roar!" Suddenly, a dragon's roar could be heard from inside Sheng Xuan's body, carrying a hint of anger.

"Has the pill begun to resist?" Sacred Xuan's lips dried up and he shook his head. Then, he tried to mobilize the soul force within his body to strike at the dragon core in an attempt to force out the dragon soul within. However, the dragon core began to spin on its own, forming a protective barrier around itself.

"I don't believe that I can't refine you!" Sheng Xuan was infuriated. It was true that at the peak of the dragon core, he wouldn't be able to compete with it, but the dragon core that Wu Guang gave him had already existed for thousands of years. Even so, the amount of demonic spiritual energy left would be insufficient.

While Sheng Xuan was at his wit's end, his gaze suddenly fell upon the wooden sword …

"Can I use this sword?" As if skeptical, Sacred Xuan picked up the wooden sword. But, he also realized another problem, and that was how to use it!

Sheng Xuan bitterly smiled, his dantian was still in great pain. He quickly gathered his spirit and concentrated on dealing with the dragon core in his body.

At this moment, the dragon core underwent another change, and a layer of black energy appeared around it. The moment Sheng Xuan's spirit energy touched the ring, it also turned black, then spread out until all of his meridians were dyed black except for the purple royal vein. Even the surface of his body had turned completely black.

"This is a backlash!" Thinking of this, Sacred Xuan couldn't help but be greatly shocked. This was bad, too much fun. It had to be known that the backlash the body refiner suffered during the tempering of the core wasn't a joke. It was similar to a cultivator's possession.

But at this very moment, another change occurred. The wooden sword that hadn't moved at all suddenly turned into a sword ray that pierced toward the dragon core inside Sheng Xuan's body. Moreover, within his body appeared a different cyan colored meridian.

"What's that?" A dragon vein? " Sheng Xuan suddenly realized that this was the Azure Dragon bloodline that his mother had mentioned earlier.

As soon as the wooden sword entered Sacred Xuan's dantian, it instantly exploded into a ball of fire. Sacred Xuan couldn't help his pupils from shrinking, "My wooden sword!"

However, when he saw it clearly, he was relieved because the wooden sword didn't explode. There was only a lot of fire coming out of the sword and it was actually roasting the dragon core.

Seeing this, Sacred Xuan couldn't help but bitterly smile, "Are you planning to roast the dragon core?"

"Xuan'er, listen to me. This Dragon Core was left behind by an ancient devil dragon." Suddenly, an ancient voice called out, causing Sacred Xuan to be stunned, "Grandpa Wu Guang!"

The voice continued, "This is a small spell that I sealed in the wooden sword to help you force out the Demon Dragon Soul. However, after forcing out the Demon Dragon Soul, you will have to rely on yourself.

Following which, waves of green light flowed out from the green dragon vein and attached onto the dragon core. It seemed that they were still absorbing the energy of the dragon core!

At this time, Sacred Xuan could only quietly watch from the sidelines, because he couldn't move a muscle.

Under the dual attacks of the dragon vein and the wooden sword's flame, the black hue of Sheng Xuan's body began to fade back into the dragon core. Then, a dragon roar came from inside his body, and an inky black dragon appeared in front of him.

"Demon Dragon Soul!" Sacred Xuan stared at the dark black dragon soul in front of him, his eyes burning with fervor, "Good heavens, he's finally appeared!"
