In the world of "Covering the Sky," Ye Fan repeatedly invited me to come out of seclusion.

"boom!"

A sea of ​​lightning descended from the sapphire-blue sky, and a terrifying heavenly tribulation engulfed Hua Yunfei in an instant.

The purple sea of ​​lightning evolved into a small world, trapping Hua Yunfei inside.

Instantly, Yao Xi's expression changed. It had only just begun, yet she had already seen the Five Elements Divine Thunder, Yin Yang Divine Thunder, and so on.

This was many times stronger than her heavenly tribulation.

"He's so powerful..." Yao Xi had never fought Hua Yunfei before and didn't know how strong he really was.

One can usually get a glimpse of a genius from the intensity of their tribulation; the more powerful a prodigy, the more intense their tribulation.

Amidst the sea of ​​lightning, Hua Yunfei stood tall in the void. Although he was cleaved in two by the lightning, his eyes shone brightly as he used the tribulation to temper his form and spirit.

An hour later, the tribulation finally ended. Hua Yunfei's body crackled and popped as his physical body rapidly recovered, becoming crystal clear and increasingly solid.

After his divine sense was tempered by the heavenly tribulation, it grew much stronger, and his essence, energy, and spirit were elevated to a new level.

"Let's go..." He landed in front of Yao Xi, his body spotless and his skin clear, like a celestial being descended to earth.

Even Yao Xi couldn't help but take a second look.

Back in the central basin, Hua Yunfei activated the celestial placenta, sensing in which direction the thing that had previously caused its unusual activity was located.

"That's... Divine Source Liquid!"

Hua Yunfei's gaze was immediately drawn to a small puddle as he glanced around.

Ahead was a small puddle, about three feet square, filled with a crystalline liquid that exuded a rich aura of heaven and earth.

Hua Yunfei arrived at the small puddle, his face showing surprise.

This was the first time he had ever seen such a thing. For the Holy Land and the Ancient Aristocratic Families, the Divine Source Liquid was especially important.

This thing can seal away powerful individuals and preserve them as a reserve, which can turn the tide in critical moments.

"This is the Divine Source Liquid? Something that only ancient emperors could refine is everywhere here..."

Yao Xi was somewhat surprised. She didn't understand Source Techniques and had only had doubts before, but she spoke up now.

"There are so many here?" Hua Yunfei asked in surprise.

"Indeed, I took a stroll around here during my cultivation and saw quite a few puddles like these."

Yao Xi replied.

Hua Yunfei thought about it and realized it was normal. After all, it was a Chaotic Divine Land that was a rare sight throughout the ages, so it wouldn't be surprising if any rare treasures appeared there.

Compared to the Mother Qi Source Root of All Things and various immortal metals, the Divine Source Liquid can only be considered an ordinary substance.

"where did you go?"

Yao Xi was somewhat surprised to see that Hua Yunfei had not returned to the low hill in the center.

"Go find something." Hua Yunfei didn't say it explicitly, but gestured for Yao Xi to follow quickly.

"So mysterious..." Yao Xi muttered to herself, but still followed.

After traveling thousands of miles, a rocky mountain appeared ahead, no more than a few hundred feet high and stretching for dozens of miles.

Hua Yunfei was surprised. He used his Origin Technique to observe the terrain and discovered that this place was far more complex than it appeared.

Just then, the placenta deep between his brows trembled slightly, confirming to him that something strange must be going on here.

"How come there's a rocky mountain here?"

Yao Xi landed beside Hua Yunfei. She was tall and slender, like a saint walking among mortals, and her whole being radiated an amazing glow.

Hua Yunfei was shaken. He sensed a familiar aura here and made a guess in his mind. He quickly moved deeper into the stone mountain.

Soon, he discovered a mysterious ancient cave beneath the largest stone mountain. The cave entrance emitted celestial light, was shrouded in chaotic energy, and was witnessing the unfolding of a wondrous spectacle of creation.

"That ancient cave must contain unparalleled treasures!" Yao Xi, who had caught up from behind, exclaimed excitedly.

She was stunningly beautiful, but at this moment she was as excited as a little woman, grabbing Hua Yunfei's sleeve and trying to rush inside.

Hua Yunfei was speechless. This woman usually seemed calm and composed, but in reality, she was a little money-grubber.

He raised his hand and tapped Yao Xi's smooth, white forehead, feigning seriousness as he said, "Don't be impulsive..."

Yao Xi glared at him, but didn't do anything else.

Hua Yunfei summoned the Devouring Demon Jar and slowly approached the edge of the ancient cave with Yao Xi.

The cave entrance is tens of feet high, and inside it is chaotic and turbulent, as if the world is being created, with countless rays of light.

The cave is a hidden world, and no one knows how deep it is.

"What's in there? Can we go in?"

Yao Xi asked nervously and excitedly, her fists clenched tightly.

"Don't move..."

The cave was filled with a primordial aura, and Hua Yunfei knew where he was.

The place where the primordial energy of all things is born!

He had come into contact with Ye Fan's Myriad Things Mother Qi Cauldron, and this place possessed an aura of the same origin.

Clearly, the Ruthless Great Emperor must have found the source of all things' primordial energy in this place, harvested it, and moved it to the Bronze Immortal Palace.

To Hua Yunfei's surprise, the object that caused the strange movement of the celestial placenta between his eyebrows was not in the chaotic cave, but next to the cave entrance.

He searched carefully and finally dug out a small pool about a foot square from a pile of rocks.

A mysterious liquid was flowing in the pool, shimmering with nine-colored light.

Hua Yunfei discovered that the placenta within his body was becoming increasingly active, trying to absorb the mysterious liquid before him.

His expression was somewhat solemn. Could it be that this placenta of heaven and earth truly possesses its own consciousness?

This is not good news.

He carefully sensed it using his Origin Technique and discovered that the impulse originated from within the celestial placenta.

Previously in Zishan, Master Zhang Lin of the Source Realm used astonishing methods to observe that a primordial spiritual root was being nurtured inside the placenta of heaven and earth, which was a gourd vine.

On that naturally formed gourd vine grew a small, green gourd.

Hua Yunfei guessed that the innate spiritual root must need the nourishment of this liquid, which was why it was behaving strangely.

To verify this hypothesis, Hua Yunfei directly extracted a drop of nine-colored liquid and sent it into his sea of ​​consciousness.

"What are you doing?"

Yao Xi, standing to the side, was dumbfounded.

Instead of exploring the astonishing Chaos Cave, Hua Yunfei dug out a mysterious little pool, which seemed unusual no matter how you looked at it.

Ignoring Yao Xi's question, Hua Yunfei was completely focused on controlling the drop of nine-colored liquid as it fell onto the placenta.

With a hiss, like ice and snow melting, or parched earth being moistened by water, the drop of nine-colored liquid instantly merged into the placenta of heaven and earth.

The placenta, the size of a human head, trembled gently, as if it were cheering.

With Hua Yunfei's current source techniques, he is not yet able to penetrate the outer shell of the Heaven and Earth Placenta and see the scenery inside.

However, he vaguely sensed that the innate gourd vine inside seemed to be swaying gently, growing slightly stronger.

Hua Yunfei breathed a sigh of relief. It seemed to be a good thing. This nine-colored liquid could be absorbed as nutrients by the placenta, which could accelerate its maturation.

This discovery greatly excited Hua Yunfei. Normally, such rare treasures would take tens of thousands of years to mature naturally, which is something that ordinary people simply cannot afford to wait for.

Now that there are things that can "force" its ripening, we should naturally pay more attention to such rare treasures in the future.

He guessed that this nine-colored liquid must be a companion spiritual object of the source of all things' primordial energy, since it was right next to the Chaos Cave.
