"Not good, Yin Xu is catching up again... No, Gui Mu is here too!" Han Li suddenly frowned and said urgently.

"Are they dogs? Why are they biting so tightly! We can't keep running like this. Let's just fight to the death." Baili Yan spat and said.

"I've used up too much energy. My space power can only be used once more to teleport us and create some distance between us and them. But at this rate, it really won't last long," Shi Chuan Kong sighed and said.

"It seems we can only fight to the death here... but the disparity in strength is too great. The odds of winning are a bit low!" Hu San also sighed.

"Don't be so quick to burn your boats. Since Yin Chengquan strictly forbids fighting near this palace, it must be an important place for their Nine Nether Race that can't be easily destroyed. If they're really afraid of hurting something valuable, we might as well go inside the palace and hide," Han Li said, his eyes flashing.

"This method is feasible. Master is still so thoughtful," Ti Hun said, his eyes lighting up with admiration.

The others had no objections, so Han Li and the others quickly arrived at the front of the palace.

Through the layer of light screen restriction, they could see that the two doors of the palace were tightly closed, with two huge, strange reliefs carved on them.

On the left door, the relief was filled with piles of white bones, with skeletons of different sizes and shapes stacked on top of each other, reaching from the bottom to the upper middle. At the top was a fearsome chair pieced together from various bones, on which sat a Nine Nether Race man wielding a huge scythe, his arms open and his face full of intoxicated expression.

On the right door, there were all kinds of terrifying and ferocious beasts, devouring and killing each other, with rivers of blood, giving people a feeling of a strong bloody aura rushing towards them.

Various corpses of terrifying beasts were also piled up to the top of the door, where a strange giant beast in a strange crawling posture was carved. Its body was surrounded by thick smoke, and it had huge pointed horns on its head. A blood basin-like mouth was wide open, as if to devour all the strange beasts, making people feel a little frightened.

"This restriction doesn't look simple. I'm afraid it will take a lot of time to break it," Shi Chuan Kong said, walking back and forth along the light screen outside the palace, looking at the runes engraved on the ground, his brow furrowed.

"There's no time. They're already here," Han Li said, his eyes narrowing.

With that, a dark red light flashed in his hand, and a black light flashed in the palm of his hand, revealing a black long knife.

Hu San glanced over and his gaze fell on the ferocious two-headed fox relief coiled on the knife hilt. The corner of his eye twitched slightly, and he looked at Han Li with a complicated expression.

Han Li, however, had no time to notice his strangeness. Instead, he used his mind to contact Shi Qinghou in the Blood Knife, transmitting his voice:

"Stone Friend, the situation is urgent. I have to borrow your power to break the restriction formation in front of us. Please help me."

"Li boy, I have a premonition that what is sealed inside is probably not something easy to deal with. Have you really thought it through? Do you want to break the restriction here?" Shi Qinghou's voice sounded in Han Li's sea of consciousness.

"The two chasing after us are not easy to deal with either. Time is short, please help me, Stone Friend," Han Li immediately replied without hesitation.

"Alright, since you've decided, I won't say more. You just need to fully activate the Blood Knife to chop at the restriction, and leave the rest to me," Shi Qinghou said after a moment of silence.

"Thank you."

After thanking him, Han Li then gripped the hilt of the knife with both hands, raised the knife, and drew an arc in front of him, holding the knife upright in front of him close to his ear.

His eyes narrowed slightly as he looked at the light screen in front of him, and the aura around his body began to converge rapidly, and his whole body's aura suddenly changed.

Seeing this, Shi Chuan Kong and the others all raised their eyebrows slightly and retreated a few steps, putting some distance between them and Han Li.

The look of surprise and doubt in Hu San's eyes became even stronger.

Only to see that the blood light in the eyes of the two-headed fox relief on the black long knife suddenly brightened, and in a trance, it seemed that the appearance had become a bit more ferocious. Strands of dark red light emerged from the blade, appearing particularly strange.

"Hoo, hoo, hoo..."

After shrinking rapidly, waves of aura stronger than the last began to erupt from Han Li's body, turning into visible ripples of air that impacted all around, shaking the entire underground space so that it echoed constantly.

Inside the passage outside, a black mist carrying the figures of Yin Xu and Gui Mu rushed forward rapidly.

"Not good, they went to the forbidden area and seem to be trying to break the restriction!" Yin Xu said in shock and anger.

"With their combat power, even if they join forces, they won't be able to break the Mysterious Nether Vermilion Bright Array for a while..." Before Gui Mu could finish speaking, a burst of strong vibrations came from the front of the passage.

"Damn it..." Yin Xu exclaimed, and the light in his eyes suddenly brightened.

The speed of the black mist immediately increased by a fold, suddenly flashing to the doorway of the underground space where the palace was located, and happened to see Han Li taking a step forward, waving his arms down, and slashing the long-accumulated knife towards the restriction light screen.

"Rumble"

A violent roar sounded, and the dark red light on the black long knife suddenly brightened, and blood light spewed out from the blade, condensing a huge blood-colored knife shadow that was hundreds of feet long, and fell on the layer of light screen.

It was as if a snow-colored two-headed white fox was lying on the knife shadow, turning its head and showing a ghostly smile at Yin Xu and the others.

In the next moment, a burst of violent thunder sounded.

Countless dark red electric lights burst out from the intersection of the knife shadow and the light screen, turning into an extremely irregular lightning light screen, directly blasting open a huge dome above the palace, revealing a dim sky light.

The dark red electric lights that bounced around, like the long whips of a thunder god, waved wildly, but under the impact of the air waves, they were like holding up an umbrella, and they also opened a layer of thunder and lightning light screen with a radius of dozens of feet on the square, just isolating Han Li and the others.

"It's open," Shi Chuan Kong said, staring at the place where the knife shadow fell, with a joyful cry.

Only to see that on the light screen, the runes were flashing, and the dark light was rippling, and indeed a narrow crack of more than ten feet long was revealed.

"Go, go in quickly..." Hu San said quickly.

Han Li had almost exhausted the fairy power in his body when he swung the knife before. After putting away the long knife, he immediately felt a burst of emptiness in his body.

Baili Yan and Ti Hun stepped forward, supporting him on the left and right, and flew into the light screen.

Seeing that Han Li and his party really broke the restriction, the faces of Yin Xu and Gui Mu became extremely ugly.

The two rushed towards the restriction gap at the same time, but were blocked by the layer of lightning light screen, and could only watch them push open the palace door and walk in.

When the power of the lightning light screen gradually weakened, the crack on the light screen had also closed again.

In the next moment, two rays of light shot from a distance, revealing the figures of Gui Mu and Yin Xu.

"How is it possible? They actually broke the restriction. What kind of immortal artifact is that long knife?" Gui Mu said in disbelief when he saw this scene.

"Now is not the time to say this. Damn it, these people actually escaped into the forbidden area, chase in quickly!" Yin Xu's face was ashen, and he immediately turned his hand and waved.

A black light flew out of his sleeve, but it was a black token, on which was carved a ferocious ghost head, and it emitted wisps of black light all over.

Yin Xu quickly pinched his hands, and the black token suddenly shone brightly. The facial features of the black ghost beast relief on it wriggled, as if it had come to life.

Hearing this, Gui Mu also hurriedly put away his expression and helped pinch the formula to urge the black token.

The light emitted by the black token became brighter and brighter, and the ghost face relief on it wriggled rapidly, expanding by several times, and two dazzling white lights lit up in its eyes, making it look a bit ferocious and terrifying.

Two gray-white rays of light suddenly shot out from the eyes of the ghost face relief and disappeared into the black light screen.

A crack of about ten feet long suddenly cracked on the black light screen, and then slowly split towards both sides.

Although Yin Xu and the two tried their best to urge it, the changes on the black light screen were still not too fast, and it took a dozen breaths before a gap that could be passed through was barely formed.

Yin Xu flipped his hand and put away the ghost face token. His figure swayed and flew into the restriction gap, and Gui Mu immediately followed.

As a result, as soon as the two entered the hall, they found that it was dark all around, and as quiet as before. Han Li and the others were long gone, and had obviously escaped into the depths of the hall.

The two looked at each other and immediately turned into two rays of light and chased after them, but they both tried their best to restrain the fluctuations of their aura, as if they were afraid of disturbing something.

"Yin Xu, this matter is no small matter, do you want to inform the domain lord about this?" Gui Mu asked with a hesitant expression while flying.

"Absolutely not. Don't you know his old man's temper? If he knows that we have let a few outsiders enter the forbidden area, don't even think about living. Have you forgotten what happened to Elder Yin Hou back then?" Yin Xu's expression changed when he heard this, and he immediately lowered his voice and said.

"But if we don't report it, if those people cause any trouble inside, the punishment will definitely be heavier. I'm afraid it will be difficult to die at that time," Gui Mu shuddered when he heard this, as if he remembered something terrible, but said worriedly.

"No. The restrictions in the forbidden area are extremely powerful, even you and I can't break through them. Those people escaped here, seemingly clever, but in fact they are throwing themselves into the net. Let's catch them and deal with them cleanly," Yin Xu sneered contemptuously and said.

"Alright," Gui Mu hesitated slightly and nodded in agreement.

While speaking, the two had already passed through the palace gate and a square inside.

Behind the square were seven or eight smaller palaces, and there were more than a dozen paths in the middle of the palaces, winding to the depths.

The light in the palace was very dim, and the situation beyond a hundred feet was a bit unclear, and it was filled with an invisible force of restriction everywhere, and the divine sense could not be expanded to investigate.

There was still no trace of Han Li and the others here, not even the slightest abnormal fluctuation. It was unknown where the few people had escaped to.
