I asked you to go down the mountain and get married, not to shock the world!

Jin Man glanced at Mingchuan and knew that this kid must have gained something new on this trip.

He had never been able to help the magic dragon cleanse its marrow before, and this time it was so actively looking for him, it must be about the magic dragon.

Jin Man stood up slowly and threw a wooden plaque engraved with runes to him.

"The quiet room is in the innermost room on the third floor of the library. This wooden sign can activate the formation. No one will disturb you while I'm here."

"Thank you, Elder Jin!" Mingchuan took the wooden sign and bowed to express his gratitude.

"Go." Jinman waved his hand, picked up another piece of candied fruit, and lay back down leisurely.

"Remember to return the wooden sign after use. Don't lose it."

Mingchuan responded and turned to walk into the library.

Walking up the stone steps, the corridor on the third floor was so quiet that only the sound of footsteps could be heard.

The door to the innermost quiet room was engraved with intricate array patterns. He stuck the wooden sign on the door, and the array instantly lit up, and the door creaked open.

Walking into the quiet room, it was empty except for a dark black jade platform for gathering spirits in the center, and spirit stones embedded in the surrounding walls.

The spiritual energy in the air is several times denser than that outside, and there is not a trace of impurities.

Mingchuan nodded with satisfaction, closed the door with his backhand, and placed the wooden sign in the groove beside the door.

The formation in the quiet room was activated instantly, isolating all sounds and spiritual fluctuations from the outside world.

He walked to the jade table, sat down cross-legged, and raised his hand to touch the bracelet on his wrist.

Inside the bracelet, the spirit of the evil dragon was curled up, with a faint black evil aura lingering around it.

Mingchuan took a deep breath, condensed a strand of pure spiritual power from his fingertips, and injected it into the bracelet.

"Get ready. In the next five days, we will begin the marrow cleansing and demon exorcism."

The dragon slightly opened its blood-red eyes, without making a sound, but seemed to respond to him invisibly.

The blood dragon and the fallen dragon also appeared and surrounded him.

Fallen Dragon: "Good fellow, this dragon has been corroded by demonic energy in the Demonic Abyss for a long time. Its condition is even worse than mine and the Blood Dragon back then..."

After a moment of silence, Blood Dragon said, "You must be mentally prepared. His demonic energy may not be completely eliminated in one go. This will be a long battle."

After he finished speaking, he glanced at the fallen dragon and added, "Maybe, like this guy, he will remain as a demon dragon. Only after you gather all nine dragons can you purify our dragon bodies with the Nine Dragon Sword."

Mingchuan was stunned.

No wonder he was wondering why the Fallen Dragon and the Blood Dragon hadn't changed at all after being with him for such a long time.

He nodded. "It's okay. It would be nice if we could first help him remove the large amount of demonic energy from his body so that he wouldn't be disturbed by it. At least we need to make him as energetic as you guys."

"Well, start preparing, I will guide you." said Blood Dragon.

This guy Dulong is unreliable, so I can only watch from the side.

Mingchuan sent a stream of spiritual energy into the bracelet, and that stream of spiritual energy immediately lifted the magic dragon out slowly.

The space, which was not very large to begin with, was suddenly filled with three dragons.

The stench from the dragon is the strongest.

At this moment, its body was wrapped in black air, and it lay on the ground unable to move.

The spiritual power condensed from Mingchuan's fingertips turned into a soft light band, gently wrapping the dragon's spirit body and slowly placing it in the center of the black jade platform.

The spirit gathering formation on the jade platform lit up slightly, and pale white spiritual energy lingered around the magic dragon, but was blocked outside by the black energy on its body, and not even a gap could be penetrated.

"The evil energy has penetrated into the spiritual veins. Forcing it will only hurt it." The blood dragon hovered above the jade platform.

His voice was filled with a certain solemnity. "First, use your Bone-Eroding Ice Flame to freeze the surface demonic energy. Then, use the cold energy of the Ice Soul Jade to pull it away and slowly peel it away."

Mingchuan nodded, and a layer of light blue ice flame appeared on his palm.

This is the bone-eroding ice flame he created after fusing it with the cold air of the Ice Soul Jade. It is a little more gentle and less overbearing than before.

He carefully spread the ice flame around the dragon's body. The moment the ice flame touched the black air, it made a "sizzling" sound.

The black air began to shrink slowly like spring water encountering ice, and no longer spread outward.

"That's it, don't stop." Blood Dragon continued to instruct, "Now transfer the spiritual power of the Cold Marrow Crystal into it. The pure yin energy of the Cold Marrow Crystal can neutralize the demonic energy and help stabilize its spiritual body."

Mingchuan took out a piece of cold marrow crystal from his storage bag and held it in his palm.

Silver light flashed on his fingertips, and he extracted the spiritual power in the crystal bit by bit, and merged it into the body of the magic dragon along the ice flame.

The dark blue spiritual power of the cold marrow crystal intertwined with the ice flame, forming a thin layer of ice on the surface of the dragon's spirit body.

The black air was firmly trapped under the thin ice, like ink trapped in glass, rolling around but unable to break free.

The dragon's originally curled up body trembled slightly, and a trace of pain flashed in its blood-red eyes, but it endured it and did not make a sound.

The fallen dragon looked on impatiently, swishing its tail. "Stop dilly-dallying. Can't you just burn it with phantom flames?"

"Shut up." The Blood Dragon glanced at it coldly. "The demon dragon's spirit body is already weak. The phantom flames carry the power of illusion, which will disturb its mind. Now we can only use gentle methods."

The fallen dragon curled his lips and said nothing more, just staring at the black energy on the demon dragon with a complicated look in his eyes.

He clearly remembered that there was no such trouble when he and Blood Dragon surrendered to Mingchuan before. Blood Dragon was fine and automatically recognized his master.

After being beaten up by Mingchuan, he obediently submitted to him...

Mingchuan's body absorbed the spiritual energy around him for a long time before slowly recovering.

I didn't expect that the dragon would be so troublesome now.

So much effort wasted.

Could it be that the remaining six dragons will also require more and more materials in the future?

When Dulong thought of this, he couldn't help but feel sorry for Mingchuan.

Mingchuan ignored the bickering between the two dragons and focused entirely on stripping away the evil spirit.

He controlled the ice flame and cold marrow crystal spiritual power with his left hand, picked up the ice soul jade with his right hand, and slowly injected the pure cold air in the jade into the magic dragon's spiritual vein.

The cold air traveled along the spiritual veins. Wherever it passed, the spiritual veins that were originally blocked by demonic energy began to tremble slightly, and cracks appeared in the black energy on the demon dragon's body.

"Continue!" Blood Dragon suddenly said, "There's a strand of original spiritual power deep in its spiritual veins that's resisting the demonic energy. Follow the direction of that spiritual power!"

Mingchuan's spirits lifted, and he probed his spiritual power into the depths of the dragon's spiritual veins. Sure enough, he felt a faint but tenacious golden spiritual power.

He immediately adjusted the direction of the ice soul jade's cold air, like diverting a canal into a river, pushing the cold air along the trajectory of the golden spiritual power.

The dark blue spiritual power of the cold marrow crystal followed closely behind, washing away the demonic energy in the spiritual veins bit by bit.

As time passed, the black air on the jade platform gradually condensed into a ball and was no longer as scattered as before.

The fishy smell on the dragon's body became a little lighter, its originally stiff claws moved slightly, and its blood-red eyes became more lively.

"It's almost done. Use the last piece of cold marrow crystal." Blood Dragon said, "Transfer the remaining spiritual power into it all at once and force this black energy out completely!"
