In the next moment, the Gathering Spirit Formation suddenly lit up with a gleam, a surge of scorching force burst forth, and billowing heat waves spread and instantly swept over an area of dozens of miles.

The Fire Attribute Spirit Qi within the Extreme Fire Realm began to boil uncontrollably, and the surrounding temperature rose sharply.

The white flames, originally only a few meters in diameter, suddenly began to expand, doubling in an instant.

The Gathering Spirit Formation used for stabilization immediately became unstable, on the verge of collapsing.

Yuan Ming glanced and understood what was going on.

The Fire Attribute Spirit Qi within the Extreme Fire Realm was not as abundant as in the Spiritual Treasure Space, unable to maintain balance with the Earth Core Purifying Fire. The solution was simple, increase the Fire Attribute Spirit Qi within the Extreme Fire Realm.

"First, do your best to stabilize the formation, you only need to persist for a moment." Yuan Ming instructed, then immediately moved to a nearby low-lying area.

He raised his hand and grasped at the void, a giant black hand appeared out of thin air, grasping fiercely towards the ground.

Within a few breaths, a deep pit of dozens of miles was carved out of the Extreme Fire Realm.

Subsequently, Yuan Ming went to the Red Fire Lake, directly connecting the Extreme Fire Realm with the Fire Lake, establishing a mana-condensed channel between them.

Under his guidance, the lake water started to flow swiftly into the Extreme Fire Realm, filling the deep pit he had just excavated.

As the lake water gurgled in, the pit quickly filled up, and large quantities of lake water overflowed, eventually forming a lake of dozens of miles in the low-lying area.

And as this lake gradually formed, the temperature across the Extreme Fire Realm continued to rise, and the Fire Attribute Spiritual Power contained within this small realm also increased rapidly.

Seeing this, Yuan Ming withdrew the Gathering Spirit Formation, moving the Earth Core Purifying Fire over, placing it back at the center of the lake.

The white flames gently floated for a moment, showing no signs of collapsing, settling down peacefully.

Yuan Ming observed, feeling relieved, and turned his gaze to Dian Xiaosan.

"You should know what the Earth Core Purifying Fire is used for, right?" Yuan Ming asked.

"I have heard that within the Zhu Rong Sect, there is a cultivation Fire Pool, containing this very Earth Core Purifying Fire. The cultivators of the sect receive the purifying fire baptism in the Fire Pool to break through the bottleneck of the Zhu Rong Heart Technique, advancing to the Perfect Realm." Dian Xiaosan nodded.

"That's correct. I want you to undergo the purifying fire baptism to achieve a breakthrough." Yuan Ming nodded.

Yuan Ming's talent in Fire Control was quite average, so choosing to let Dian Xiaosan break through first while he learned through the Stealing Heaven Tripod was the most efficient approach.

Hearing this, Dian Xiaosan was initially excited but soon calmed down.

"The purifying fire baptism of the Zhu Rong Sect is not merely being engulfed in flames, nor is it achievable only with the Zhu Rong Heart Technique. They also have special secret techniques for assistance. Without this secret, using the Earth Core Purifying Fire for baptism is akin to seeking death." Dian Xiaosan shook his head and smiled bitterly.

"Isn't it just the secret technique for the baptism? I can tell you that." Yuan Ming smiled.

Dian Xiaosan was startled at first, then seemed to realize something, looking at Yuan Ming in disbelief.

If the Zhu Rong Heart Technique was already a closely guarded secret of the Zhu Rong Sect, then the secret technique used to break through the bottleneck of the Zhu Rong Heart Technique was even more central to their core secrets.

Is it really something that can just be obtained so easily?

Dian Xiaosan thought of this and calmed down again, filled with doubt in his heart.

"When breaking through the Zhu Rong Heart Technique, you need to first prepare a Heart Fire Inheritance Array, and then..." Yuan Ming didn't pay attention, carefully describing the breakthrough process he saw in Yan Jue's memories to Dian Xiaosan.

The more he listened, the more alarmed he became, his expression turning from initial doubt to seriousness, then shock, and finally to sheer joy.

"According to this method, it might actually be possible," Dian Xiaosan muttered to himself after a long time of coming to his senses.

"The secret technique I taught you, you should carefully comprehend it. To maintain the existence of the Earth Core Purifying Fire requires a lot of Fire Attribute Spirit Qi, and although this lake can sustain it for a time, it is not a long-term solution, so you need to start breaking through quickly." Yuan Ming glanced at the lake water and said.

When he completes his own breakthrough, Yuan Ming himself might also need to use the Earth Core Purifying Fire for breakthrough, so time was of the essence.

"I understand." Dian Xiaosan immediately nodded.

With that, he closed his eyes, meticulously reviewing the information on the baptism Yuan Ming had given him, carefully analyzing every detail of the secret technique.

A moment later, Dian Xiaosan opened his eyes again and said, "I can start attempting now."

Hearing this, Yuan Ming was overjoyed, immediately taking out various Magic Artifacts for arraying, arranging them around the lake. Soon, a Heart Fire Inheritance Array was set up.

"You can begin." Yuan Ming said.

"The time needed for a breakthrough is hard to estimate. If it takes too long, can the Earth Core Purifying Fire be maintained?" Dian Xiaosan raised his concern after some deliberation.

After analyzing the baptism breakthrough process in detail, this was his only worry.

"You can rest assured about this, I will search for more treasures containing Fire Attribute Spiritual Power in the Secret Realm later, continuously feeding them into the lake to ensure a constant supply of Spiritual Power, preventing failure due to insufficient Spiritual Power." Yuan Ming promised.

Dian Xiaosan heard this and hesitated no further.

He formed seals with his hands, performing the secret Zhu Rong Sect's Burning Body Technique, enveloping himself in his own flames. Using the Heart Fire Inheritance Array as a guide, he activated the Zhu Rong Heart Technique, and leaped into the white flames at the center of the lake.

The Earth Core Purifying Fire surged and closed in from all directions, wrapping him in its center.

At this moment, Dian Xiaosan was like the wick of a flame in an oil lamp, engulfed by fire yet unharmed, completing his purification under the burn of the Earth Core Purifying Fire.

Yuan Ming watched for a while; seeing him calm and unscathed, he then left the Shura Palace and came outside.

At this moment, Wulu and Nan Shangfeng had also finished their Breathing Control, waiting for a long time.

Yuan Ming and Nan Shangfeng discussed a few words and decided that Nan Shangfeng would travel together with Yuan Ming and Wulu.

The three promptly set off, continuing their journey, and soon flew out of the Fire Lake range.

But just then, a golden light rapidly descended from the high sky in the distance, the tunneling light receding to reveal a delicate figure landing gracefully in front of them.

Upon seeing the visitor's appearance, Yuan Ming and the others showed expressions of surprise.

The visitor was a sixteen or seventeen-year-old girl, astoundingly beautiful—wasn't it Wu Yu?

But looking at the person before him, Yuan Ming couldn't help but frown.

This girl, whom the Great Demon Kings of the Ten Thousand Demon Country all obeyed, appeared before them—what could be the reason?

Externally, her attire was as before, still that dignified and luxurious golden robe, but the aura emanating from her now seemed much weaker than before.

Yuan Ming noticed her cultivation had returned to the Returning to Void Peak, as if reminiscent of their first meeting at Black Tiger City.

"Fellow Daoist Wan, I've come over this time..." Wu Yu began, but was interrupted by Yuan Ming.

"You're not the main body, are you?" Yuan Ming asked.

Upon hearing this, Nan Shangfeng couldn't help but show a look of surprise, scrutinizing Wu Yu carefully.

"That's right, I am just a clone; the main body is elsewhere." Wu Yu paused slightly and calmly admitted.

Yuan Ming nodded and gestured for her to continue.

"I've come to see you this time to ask you to fulfill the promise you made back in the Ten Thousand Demon Mountain Range," Wu Yu continued.

Yuan Ming naturally remembered this; he had promised to help her if he could as gratitude for Wu Yu's kindness back then. He hadn't expected her to ask him to fulfill it now.

"Fellow Daoist Wu Yu, you are quite the strategist. You've been setting me up since our first meeting at Black Tiger City. Did you anticipate the current situation back then?" he said calmly.

"Back at Black Tiger City, due to certain reasons, I had to hide my identity, and I hope Fellow Daoist Wan won't mind," Wu Yu said, bowing solemnly to Yuan Ming.

Seeing this, a trace of surprise flashed in Yuan Ming's eyes.

Wu Yu was the Empress of the Ten Thousand Demon Country, and although the one in front of him was just a clone, she actually bowed to him? Could he really wield such influence?

"Fellow Daoist Wu Yu, you're overdoing it. We are old acquaintances, and if we set aside our Human and Demon Clan positions, we're friends. However, I'm just an ordinary loose cultivator, with limited abilities and not much I can do to help you." He chuckled, speaking vaguely.

"Fellow Daoist Wan, you have already broken through to the Dharma manifestation Stage, with exceptional strength, and will undoubtedly become famous in the Chuyun Realm. Why undervalue yourself?" Wu Yu said with a smile, tidying her sideburns.

"Fellow Daoist Wu Yu, flattery is unnecessary. Since I made the promise, I won't renege on it. Just tell me what you want me to do. As long as it doesn't involve siding with the Ten Thousand Demon Country against my clan, I will give it serious consideration." Yuan Ming dusted his sleeve and asked directly.

With Dian Xiaosan's casting, the Spiritual Power within the Extreme Fire Realm's Fire Lake was being continuously consumed, and he needed to quickly find Fire Attribute spiritual materials to replenish it. He had no time to chat idly with Wu Yu.

"Rest assured, Fellow Daoist Wan; I have no intention for you to betray the Human Clan. I only ask that you ensure not to attack the demons of the Ten Thousand Demon Country while in this Spiritual Treasure Space," Wu Yu smiled and said.

"If that's all, it's no problem. However, the premise is that the demons of the Ten Thousand Demon Country also cannot attack me. Otherwise, I will choose to retaliate," Yuan Ming said in astonishment, pondering slightly before speaking.

"Of course," Wu Yu relaxed, smiling.

"If that's the case, then let's leave it at that. We still have treasure hunting to do, so we'll take our leave." Yuan Ming said, flying ahead.

"Fellow Daoist Wan, please wait; I have something else to tell you," Wu Yu suddenly called after Yuan Ming.

Yuan Ming stopped in his tracks, looking over suspiciously.

"Actually, the Ten Thousand Demon Country has discovered some clues about this Space Spiritual Treasure we are in. As a thank you for not attacking the cultivators of the Ten Thousand Demon Country, I am willing to share this information with you," Wu Yu spoke on her own.

"Please, Fellow Daoist, do tell," Yuan Ming slightly furrowed his brow, replying.

"The origins of this Space Spiritual Treasure may very well be the legendary Three Realms Immortal Boat," Wu Yu said.

Upon hearing this, Yuan Ming froze slightly; it was the first time he had heard this name, and a sense of perplexity filled his heart.
