I am the son of the Dragon God in Douluo Continent.

A few hours before the meeting, Xu Xingyu and Gu Yuena quietly arrived above the Mingdu Imperial Palace.

Using their divine senses, the two concealed themselves directly above the palace, looking down at the magnificent building that symbolized the highest power of the Sun and Moon Empire.

The Ming Dynasty Imperial Palace is magnificent, resplendent, and unique in its architectural style.

Towering city walls surround the vast palace complex, with the main hall standing in the center, surrounded by meticulously arranged gardens and flowerbeds.

The palace roof, covered with golden glazed tiles, still shimmered slightly even in the dim moonlight.

In front of the tall city gate, there were two rows of neat and orderly guards, solemn and dignified.

The palace was surrounded by a high-tech soul-guided protection system. Concealed soul-guided turrets, sensitive detection devices, and multi-layered energy shields formed an impenetrable defensive line.

With the addition of the Imperial Dragon Soul Master Corps guarding the palace, this place is arguably the most heavily guarded location in the entire Sun Moon Empire.

Anyone attempting to enter the palace without permission will either be immediately detected and intercepted by these security systems, or captured by the Imperial Dragon Soul Mentor Corps.

Looking at the palace before her, Xu Xingyu commented with a hint of admiration, "This defensive system is quite impressive, far surpassing the defenses of the palaces of the other three kingdoms."

"Looking at these security systems makes me want to upgrade the security at our Qiling Tower headquarters."

Gu Yuena chuckled softly, her voice carrying a hint of confidence: "However, it is still useless in the face of divine sense."

Xu Xingyu smiled helplessly at this: "There's nothing we can do. Items that can isolate divine sense are extremely rare in places like Douluo Continent where the spiritual energy is weak."

"Moreover, in the entire Douluo Continent, besides you and me, there is no one else who can cultivate spiritual power at the divine sense level. Di Tian may be able to, but he has not yet reached that level."

In response, Gu Yuena said, "Actually, Di Tian reached the level of divine consciousness a long time ago, but he suppressed it to avoid attracting too much attention from the divine realm. Of course, his spiritual power is still relatively weak compared to yours."

"Oh, I didn't know that was the case?"

After chatting for a while, the two began their journey here.

Their divine senses were simultaneously activated, completely concealing their auras. They easily evaded all the protective systems and quietly infiltrated the palace.

After entering the palace, they carefully inspected various areas.

They carefully explored every palace, every courtyard, and even the most secluded corner.

However, despite using their divine sense to analyze every part of the palace, they still couldn't find anything suspicious.

Just as they were feeling somewhat disappointed, Xu Xingyu's communicator vibrated. He took it out and saw that it was a message from Wang Dong'er.

The message read: "Senior Brother He Caitou has provided clues about a secret realm hidden deep within the palace. This secret realm seems to be the source of the jade-colored crystal that you obtained before, Xingyu. The specific location is provided in the attachment."

Xu Xingyu glanced at the map in the attachment and a hint of surprise flashed through her mind, because according to the map, the secret realm was located underground in the palace.

Although he and Gu Yuena had not yet personally gone to see the underground area, their previous divine sense detection had not shown anything unusual about the place.

Seeing this, Gu Yuena felt a strange unease and turned to Xu Xingyu, asking, "What should we do? Should we believe him?"

After thinking for a moment, Xu Xingyu said, "Let's trust He Caitou for now. Without the help of our Qiling Tower, he won't have the power to take revenge on the current Sun Moon Royal Family."

"And even if he might have other intentions, the seed of the Sun God's premonition that I gave him is enough for me to take his life at any time."

"Then I'll do as you say."

Following the map attached, Xu Xingyu and Gu Yuena carefully navigated through layers of guards and protective systems, finally arriving at the entrance to a hidden underground passage.

They entered the passage and descended the narrow, deep stone steps. The walls of the passage emitted a faint fluorescent light, reflecting an emerald green hue.

The further they went, the more they could sense a strange energy fluctuation in the air.

When they finally arrived at the location indicated on the map, a spacious underground hall appeared before them.

In the center of the hall stood an emerald-colored altar, surrounded by a complex and ancient array that seemed to be no match for any soul-guiding array in the present day.

The altar was inlaid with countless crystal-clear emerald-colored gemstones, radiating a dazzling light.

"This place..." Gu Yuena frowned, sensing the distortion and instability of the surrounding space. "The space here seems to be distorted by some kind of force."

As Xu Xingyu stepped into the altar, she suddenly felt the Dragon God bloodline within her begin to throb uncontrollably.

He could feel a strong resonance, as if the altar was echoing his bloodline.

The emerald-colored gemstone on the altar then lit up, emitting a dazzling light.

"It seems the altar is responding to my bloodline," Xu Xingyu said softly.

"But isn't this a place only those who have possessed the Purple Emperor Annihilation Dragon Martial Soul throughout history are allowed to enter?" Gu Yuena said, filled with doubt. "The Purple Emperor Annihilation Dragon and the Dragon God are mortal enemies. How could a place related to it welcome someone like you, a possessor of the Dragon God's bloodline?"

Who knows?

Just then, the emerald light on the altar grew stronger and stronger, eventually forming a dazzling pillar of light that instantly enveloped Xu Xingyu and Gu Yuena.

Before the two could react, they were swept into it by the powerful spatial force.

The moment the two figures vanished, an old man deep within the palace suddenly opened his eyes. "This spatial fluctuation? Could it be that something's wrong with the secret realm?"

At that moment, the man in the wheelchair next to him asked in surprise, "Elder Kong, are you sure? Not only is the outer perimeter of the secret realm heavily guarded, but the condition for entering the secret realm is that only those who possess the Purple Emperor Annihilation Dragon Martial Soul can enter."

The old man, known as Master Kong, narrowed his eyes slightly, sensing the subtle changes in the air. "That's right, such strong spatial fluctuations only occur when the secret realm opens. It seems that those who enter the secret realm are no ordinary people, having managed to bypass its restrictions."

"Your Highness, please allow me to lead some people to the teleportation altar in the secret realm to see what exactly happened."

The man in the wheelchair was Xu Tianran. He originally had something to discuss with Kong Deming, the only level 10 Soul Master of the Sun Moon Empire, hoping to bring him into his camp, but he didn't expect this to happen.

Xu Tianran nodded, his expression solemn. "Elder Kong, please be sure to bring me along. You also know that to enter the secret realm, one must possess the Purple Radiance Annihilation Dragon Martial Soul."

"And in the current palace, only I have the purest Purple Radiance Extinction Dragon bloodline flowing through my veins. Without my help, you can only watch helplessly from the altar."

"This... Your Highness, but your safety..." the old man said hesitantly.

"It's alright. I believe that with Master Kong around, no enemy can hide from us." Xu Tianran said confidently. "Moreover, the secret realm is the foundation of our Sun Moon Imperial Family. If we lose the secret realm, the loss to our Sun Moon Empire will be severe."

"I understand. Then I apologize for my rudeness."

After saying this, the old man picked up the person and wheelchair together, then transformed into a silver streak of light and headed towards the location of the secret realm.
