"It's great that this place wasn't affected by the war!" Seeing this scene, Immortal Venerable Firejoy's face showed joy, and he breathed a long sigh of relief.

"The area around this hall has been tampered with, it probably won't be easy to enter." Han Li said, looking at the empty void around the palace, his eyes flashing with purple light.

"Indeed, the Two-Yin Micro-Dust Formation of our sect is deployed around here. This formation is one of the most powerful hidden killing formations of our sect. Even an existence in the Grand Luo Realm would find it difficult to detect. Fellow Daoist Li is actually able to sense the existence of this formation!" Immortal Venerable Firejoy revealed a hint of surprise and looked at Han Li's purple pupils a few more times.

"Since Fellow Daoist Firejoy is so confident, do you already have a way to enter?" Han Li retracted his pupil technique and asked.

"It would naturally be extremely difficult for outsiders to enter, but with me here, Fellow Daoist Li can rest assured." Immortal Venerable Firejoy laughed heartily.

Then, with a flip of his hand, a silver jade plate appeared and was thrown upwards. At the same time, he cast a magic spell with his other hand, which flashed and disappeared into the silver jade plate.

Immediately, the surface of the jade plate shone brightly with silver light. With a shake, it transformed into a silver sphere of light, enveloping himself and Han Li.

Immortal Venerable Firejoy chanted an incantation, and after a moment, he pointed remotely at the palace in front with a solemn expression.

The silver sphere of light immediately flew towards it, not too fast.

After flying a short distance forward, the surrounding void buzzed suddenly, and white rays of light, both vertical and horizontal, appeared.

These white rays of light were of various lengths and sizes, spread across an area of about ten miles around the Mantra Palace, rolling and rotating constantly, evolving into various changes.

"The Two-Yin Micro-Dust Formation..." Han Li muttered to himself, watching the white light outside, his eyes flashing with purple light.

These white lights were just the most superficial changes of this formation. The deeper changes were extremely complex. Under the exploration of his Nine Serenities Devil Eyes, countless white light spots of various sizes also appeared in the surrounding space, flashing constantly, truly dazzling and colorful.

But if you looked closely, each of those light spots faintly contained a small, independent world, with mountains, rivers, birds, beasts, blue seas, and blue skies, exceptionally real and mysterious.

Han Li's expression changed slightly upon seeing this.

This Two-Yin Micro-Dust Formation was much more mysterious and powerful than he had imagined.

Although these light spots looked dazzling and mysterious, they were actually connected in some way. If one were to touch them rashly, it would immediately trigger the entire Two-Yin Micro-Dust Formation, and one would be subjected to the full force of this formation's annihilation.

Although Immortal Venerable Firejoy spoke confidently, his expression was still extremely solemn. He quickly made hand seals with both hands, carefully controlling the silver sphere of light to move forward, not daring to make a single wrong step.

It took a full half an hour for the two of them to barely pass halfway.

The situation of the formation in front suddenly changed again, and black light spheres like water droplets appeared, rotating and spreading out circles of black ripples.

As those ripples gradually expanded, the scenery in front gradually became blurred, revealing a strong sense of desolation.

"The restrictions of the formation in the second half are even more troublesome. I need to concentrate all my energy. Fellow Daoist Li must not disturb me." Immortal Venerable Firejoy said to Han Li, looking at the scene in front.

"Don't worry." Han Li naturally knew the importance of the matter and nodded.

Immortal Venerable Firejoy also knew that Han Li was a steady person. He said this to prevent any unexpected events.

He took a deep breath and was about to urge the silver sphere of light to continue moving forward.

At that moment, the black ripples in front suddenly became violently disordered and quickly dissipated.

Those black water droplet light spheres also rapidly shrank several times and激荡 violently. The space in front instantly became clear, and the gate of the Mantra Palace could be faintly seen.

The formation behind the two was the same. All the white light quickly dimmed, and the restrictions also quickly dissipated. It was unknown what had happened.

Han Li was immediately stunned upon seeing this scene.

Immortal Venerable Firejoy was also stunned, but he immediately cast a spell to urge the silver light sphere to move forward quickly. In a few breaths, he passed through the remaining formation area and landed in front of the gate of the Mantra Palace.

"What's going on? Why is this formation suddenly so turbulent?" Immortal Venerable Firejoy turned around and looked at the violently激荡 formation behind him, muttering to himself.

"The core of this formation should be inside the Mantra Palace, right? I guess something happened inside." Han Li said, looking towards the gate of the Mantra Palace.

"What! Could it be that someone has already arrived here before us?" Immortal Venerable Firejoy's face changed upon hearing this, and he also turned around and looked towards the palace.

The gate of the Mantra Palace did not seem very tall from a distance, but the two of them truly felt the grandeur of this palace at this moment, standing at the gate.

The two of them stood at the entrance of the palace, like two small ants, further highlighting the magnificent and spectacular nature of the Mantra Palace in front of them.

Looking ahead, the entrance of the palace was a long passage, but the light inside the passage was very dim for some reason.

With Han Li's eyesight, he could only see a range of a few tens of feet while standing at the door. The deeper parts were shrouded in darkness, giving people a strange feeling of unfathomable depth.

With a thought, he penetrated his spiritual sense inside. The dark passage in front was filled with an invisible force, which unceremoniously bounced his spiritual sense back.

Han Li frowned slightly and looked towards Immortal Venerable Firejoy, with a questioning look on his face.

"Fellow Daoist Li, don't ask me. This is also my first time here. As for the Two-Yin Micro-Dust Formation outside, I only happened to see a diagram of this formation before, so I know how to pass through it." Immortal Venerable Firejoy spread his hands and said.

"Now that we're here, there's no way we can retreat now. Let's go." Han Li pondered for a moment, said a sentence, and then stepped into the palace gate.

Immortal Venerable Firejoy, seeing this, quickly followed closely behind and walked in.

The passage was dark. It seemed that some special restriction had been placed here. No matter what Han Li and the other used for lighting, the light could only emit a range of a few tens of feet.

Beyond this range, everything was shrouded in darkness.

The surroundings were silent, and only the sound of the two people's footsteps echoed.

In the blink of an eye, Han Li and the other walked inside for a quarter of an hour. This passage was longer than imagined and showed no signs of ending.

With the unknown danger ahead, the two did not dare to speed up. Step by step, they walked forward honestly.

It was just that the silent space, and the unchanging stone walls on both sides, made people feel extremely depressed and uncomfortable as they walked through it.

Before long, Immortal Venerable Firejoy's breathing gradually became heavy.

Even Han Li gradually felt a bit of annoyance in his heart at this time, and seemed a little impatient.

At this moment, a subtle sound came from the front, faint and elusive, seeming to be the sound of someone crying.

Han Li's eyes narrowed, and he immediately stopped walking, instantly raising the immortal spiritual power in his body.

But the sound in front suddenly disappeared, as if it had just been an illusion.

"Fellow Daoist Firejoy, did you hear..." Han Li looked towards his side, his face suddenly stiffened, and his voice stopped abruptly.

Immortal Venerable Firejoy, who was originally walking next to him, was now nowhere to be seen and had disappeared suddenly without knowing when.

"Fellow Daoist Firejoy!" Han Li shouted loudly, using a bit of true power. His voice echoed rumblingly, shaking the nearby ground and walls violently.

But there was no response around. Immortal Venerable Firejoy seemed to have really disappeared.

"Could it be that I'm under an illusion?" Han Li's face sank. He immediately ran the vast divine sense power in his mind, but he did not feel anything unusual. It did not seem like he was under an illusion.

"Fellow Daoist Demonlight, you..." He looked towards the Flower Branch Space, and his divine sense contacted Demonlight.

Halfway through the question, Han Li's voice stopped again suddenly.

His connection with Demonlight had also disappeared. The divine sense in his mind seemed to be imprisoned by a mysterious force, unable to leave his mind at all.

Not only the Flower Branch Space, but he had also completely lost contact with the storage magic tools on his body.

Han Li's face finally sank.

Although this situation did not necessarily mean that he had fallen into an illusion, it was obvious that he had been affected by some kind of restriction in the passage.

His eyes flickered and he glanced at the front and back. After pondering slightly, he suddenly walked forward quickly.

He had been in this passage for a long time. Retreating now would mean giving up all previous efforts. Moreover, even if he wanted to retreat, he might not be able to retreat now.

Han Li continued to walk forward. Not far after, a flash of black light suddenly appeared in front of him. A sharp whistling sound rang out, and a black light arrow shot towards him, aimed directly at his chest, with astonishing speed.

Although his vision was only a few tens of feet at this moment, his reaction was extremely agile. He took a step to the side and easily avoided the arrow.

Whoosh!

The black arrow flashed past and disappeared into the darkness behind, without a trace.

"Who's being so sneaky?" Han Li stopped walking, looked towards the darkness in front, and let out a loud shout.

Rumble!

The entire passage trembled violently, and it slowly calmed down after a while. There was no movement in front.

"Putting on an act!" He snorted coldly and continued to move forward.

As a result, just as he took a few steps, the sound of sharp whistling rang out again in front. The dark void in front trembled, and another black light arrow shot out, striking towards his body, with the same speed as before.

A trace of doubt flashed in Han Li's eyes. What was the point of these light arrows of this level? He could avoid them no matter how many came.

Thinking this in his heart, he moved his body and was about to dodge to the side.

At that moment, an even stranger scene appeared!

The only remaining light area around him suddenly flashed and disappeared, plunging him into complete darkness.

A sharp whistling sound rang out, and Han Li groaned and retreated two steps to the side.

The darkness had come suddenly. He was a moment too slow to react and was not able to completely dodge the second arrow. His shoulder was grazed by the light arrow.

He did not know what kind of supernatural power the black light arrow possessed. Although it was only a graze, Han Li felt as if someone had stabbed his divine soul with a red-hot knife, causing him excruciating pain.

"Damn it!"

Han Li suppressed the annoyance in his heart, quickly operated his immortal spiritual power, and waved his hand to emit a blue light, trying to illuminate the surroundings.

But no matter how hard he worked to emit light or sacrifice treasures to illuminate the area, the surroundings were still pitch black. He could not see anything or sense anything.
