After Ye Fan made such a bold assumption, the next step was to prove it. He had to use his own elemental powers to attempt to unravel the mysteries of the seabed.

He almost reached the deepest trench of the Death Sea. This trench is like the ocean trenches on Earth, several tens of thousands of kilometers deep. What lies beneath it is unknown to anyone. Ordinary cultivators cannot dive to such depths because below the trench, the pressure of the seawater is extremely abnormal; even cultivators above the Divinity Transformation Stage can’t withstand such powerful pressure.

"Stop trying to find anything, you won’t find anything here!" Xuannu said.

Ye Fan continued to exert psychological pressure on Xuannu, making her feel pressure from all directions. By doing so, Ye Fan could find more ways to control Xuannu, because he had sensed that as long as he could control her, the power over space would not be easily unlocked by others. It’s very likely that Pan Gu and Fu Xi have not yet awakened.

Ye Fan thought to himself, "Nuwa isn’t a fool. She knows her cultivation and achievements aren’t equal to Pan Gu and Fu Xi’s. Why would she summon them to awaken and bring her trouble? It’s plausible that Nuwa opened part of the space gateways, like the Immortal Realm gate, allowing people from the Immortal Realm to return to the Mortal World. As for some mysterious forces, they should stem from these space gateways. Could Nuwa’s ultimate aim be to first find the source of the Transcendance Tribulation and temporarily dissolve it into nothingness?"

While pondering these things, Ye Fan began to dive into the seabed. The world beneath the sea was unfamiliar to him, as the surrounding environment was no longer a traditional seabed. Even below the sea surface, the currents were still turbulent, as if the water was boiling. Ye Fan was trying to find a way to prevent these currents from obstructing his advancement.

As for Xuannu, she was dragged along behind him using Spiritual Energy. The two continued to dive deeper into the ocean. Because Ye Fan’s speed was extraordinarily fast, Xuannu was still enduring both spiritual and elemental trials, leaving her unable to sense changes in the surrounding environment.

After about three minutes, Ye Fan swiftly appeared at the seabed with Xuannu.

Upon seeing the seabed environment, Ye Fan understood why the ocean of the Death Sea was so tumultuous. It’s because there truly is a powerful energy source here, an energy source that instills fear in people. When energy cannot be released, it accumulates at the seabed, diffusing into the seawater, causing the water to change constantly.

"How many people can reach such depths after the emergence of the Pan Gu secret realm?"

Ye Fan sensed the intensity of the pressure around him. Here, even the hardest metal had long turned into granules. The sea depth here exceeded Ye Fan’s imagination, and his body’s elements could hardly withstand the pressure. It seemed like this place was pre-set, as the Pan Gu secret realm was created by ten ancient powerhouses. It seemed this setup intentionally prevents ordinary cultivators from entering.

To reach the seabed, even with artifact enchantments, one’s cultivation must be in the Ascension state. But within the secret realm, the highest cultivation can only reach the Transcendance Tribulation Stage, as ascension can’t be completed within.

At such depths, logically, light should have entirely disappeared. But perhaps due to the densely packed energy sources, Ye Fan felt there was a visually detectable glow around him. He had to investigate the source of these energy sources, seemingly coming from deeper underground, indicating there is an underground passageway below the Death Sea’s seabed, although its location is unknown.

"Turn back, you won’t find anything!" Xuannu kept insisting.

Ye Fan ignored Xuannu. Whenever Xuannu’s spiritual power relaxed slightly, Ye Fan intensified the pressure. Despite facing such immense attacks, Xuannu’s spiritual fortitude remained intact, impressing Ye Fan.

"There are some small treasures at the seabed, probably artifacts that sank here, which haven’t turned into powder. It must mean they’re quite remarkable artifacts. But where is the passage leading underground?"

Ye Fan avoided considering other issues. He focused on exploring deeper into the Pan Gu secret realm.

Some matters might be unknown to anyone besides Pan Gu and Fu Xi within the secret realm. Many situations can’t be reasoned with logic, as all space and matter here are artificially created. The only possible exception might be Heavenly Peak Mountain, but its surrounding forces are controlled by Pan Gu and Fu Xi.

As for the underground space under the Death Sea, no cultivator can reach such depths, and what exists there is unknown to anyone. It resembles the Death Sea abyss, where the deepest secrets are known only to its creators.

"The abyss of the Death Sea is Fu Xi’s laboratory. I wonder what lies even deeper here? Could it be Pan Gu’s laboratory?" Ye Fan pondered in confusion.

"Ye Fan... turn back..." Xuannu continued urging.

But at this point, what Xuannu said was of little consequence. In less than a minute, Ye Fan had explored several thousand kilometers around the seabed. After confirming the energy source below, he approached it. The spatial area was roughly only a few dozen kilometers, and Ye Fan thought the entrance might be within this range.

"Whew..."

Just as Ye Fan prepared to continue searching for the entrance, he suddenly felt a strange force swiftly shooting toward him, as if some mysterious power was attacking.

"Serves you right!" Ye Fan shouted, almost simultaneously releasing Spiritual Energy from his hand, directly attacking the incoming force. A massive explosion erupted underwater, creating a vacuum in the sea, but in a short time, the pressure forced the seawater back, restoring the water to its original state.

As for the force, it disappeared in the water, but soon an invisible force continued attacking Ye Fan.

"This is troublesome. Do I have to keep battling this force until I’m exhausted?" Ye Fan was unsure whether to continue facing the attack, but it seemed this force had the capacity to kill him. Cautious, he responded to the attacks one by one.
