As Yu Kai stepped into the Ancient Star Pattern Hall, he was instantly captivated by the scene before him. Though dilapidated, with mottled walls and broken pillars, the hall still exuded an aura of ancient majesty, as if speaking of a glorious past. The chaotic aura surrounding him, like a gentle mist, wafted towards him, leaving him with an indescribable sense of comfort. Simultaneously, the power system behind him, like a glutton sniffing a delicious treat, rapidly absorbed this chaotic aura. As the chaotic aura poured in, his previously depleted spiritual energy was restored at an astonishing rate.

His eyes were first drawn to the chair on the dais directly in front of him. It was made of some mysterious material. Though battered and peeling in places, its remaining charm was still clearly discernible, instantly recognizing it to be made of some extremely precious material. Yu Kai's mind raced, thinking to himself, if it could be incorporated into the mecha, its defense would surely be significantly enhanced. If used to repair the Moon Spirit Holy Sword, perhaps even its power would be enhanced to a new level. It was truly an exceptional material.

At that moment, the voice of the Devouring Array Beast urged him urgently in his mind, but Yu Kai ignored it and carefully tucked the chair back into his inner space, fearing that any movement would damage the treasure. After stowing the chair, he looked up and saw a vast sea of ​​stars overhead, shimmering with dazzling light, like an ancient and mysterious star map. Each star radiated a unique brilliance, marking the vast area once ruled by this place. Yu Kai couldn't help but feel a surge of emotion. He thought, with so many stars, even if each one contributed only a trace of their stellar power, when combined, he would become incredibly powerful, and he would not be so defenseless before Zhang Daoling, allowing him to suppress him at will.

He concentrated on engraving the appearance of this sea of ​​stars in his mind, hoping that perhaps one day he would be able to visit this mysterious place and explore its mysteries.

Yu Kai withdrew his gaze and began to survey his surroundings. He saw figures of various shapes carved into the walls, most of them blurred and incomplete, like fragments eroded by time, covered in thick dust, as if they had slumbered for countless epochs. Curious, Yu Kai slowly approached and gently touched a portrait of a human figure.

The moment his hand touched the portrait, something strange happened. The entire wall suddenly lit up with sharp rays of light, like blades, slicing through the darkness within the ancient hall. Immediately afterwards, countless powerful fragments of laws burst forth from the figure on the wall like cannonballs.

These fragments of the law were incredibly powerful. Wherever they passed, the air shrieked, as if sliced ​​by a sharp blade. Yu Kai was caught off guard and, hastily channeling his spiritual energy to block the impact, was still struck by one of the fragments, sending him flying. A hideous hole was blasted through his mecha, and blood slowly flowed through the cracks, pooling on the ground in a small, crimson patch.

Blood dripped onto the ground, as if triggering some ancient mechanism, activating a long-hidden formation. Mysterious lines instantly appeared on the ground, emitting a soft, strange glow, like brilliant stars twinkling across the earth. The lines quickly illuminated, spreading outward from Yu Kai at the center, with lightning speed. Finally, they fully activated the surrounding walls. As if awakening from a long slumber, mutilated figures came alive within the mural world. They roared to the heavens, emitting a terrifying and chilling pressure.

Yu Kai was deeply shocked. He clearly felt that if any figure in the mural walked out, it would be enough to shock the entire immortal world. Even if a trace of aura leaked out, it could easily kill Zhang Daoling.

They all seemed to be the strongest people standing at the top of an era, representing the supreme glory and power of that era.

However, these figures that left their mark on the wall world should not have come from the prehistoric fairyland. After all, Yu Kai had never heard of any legends about them.

"Boy, come in quickly, come to this mural world. These figures are all ancient sages from other fairy realms. The imprints they left behind are too old and have gradually dissipated. These fragments of laws are already very weak, which is just enough for you to comprehend. Once they are integrated with your own understanding, your strength will increase greatly." The voice of the Array-Devouring Beast came from the mural world this time, and its tone seemed a little excited, as if urging Yu Kai to seize this rare opportunity, and at the same time hoping that he would rescue him as soon as possible.

Yu Kai knew this might be a rare opportunity to improve his strength, but the raging fragments of laws before him were like a series of dangerous obstacles. If he rashly entered the mural world, his life would be in jeopardy. But when he thought about his own enhanced strength, he would no longer be bullied, especially being able to escape Zhang Daoling's suppression. He gritted his teeth and without hesitation, he transformed into a stream of light, his body moving like lightning, resisting the raging fragments of laws and rushing towards the wall.

Upon entering the mural world, Yu Kai felt as if he had entered a completely different time and space. The aura of chaos here was as thick as substance. With every breath, he could feel the power of chaos flowing through his body. His body, which had just been pierced by the fragments of the law, was rapidly recovering.

He was standing in the center of a vast square, paved with a strange black rock that shimmered with an uncanny luster, as if imbued with endless mysteries. Towering stone statues stood around him, representing the ancient sages depicted in the murals. Their forms varied, some with awe-inspiring expressions, others with profound gazes, as if they were surveying the world.

Above the square, four holy swords, filled with murderous intent, hovered. "Are these the legendary Immortal Slaying Swords of Tongtian Patriarch? Legend has it that when combined, these four swords possess the power to disrupt yin and yang, slay immortals and slay saints. Their blades gleam with an icy light, as if they can cut through everything in the world. The surrounding space is even slightly distorted by the presence of these four swords," Yu Kai muttered, his eyes filled with wonder.

"Senior, where are you?" Yu Kai looked around anxiously for the trace of the Formation-Devouring Beast, but there was no trace of it.

"Boy, stop looking. Your actions just now seem to have activated the inheritance test here. Ever since you came here, they have sealed me directly under the square!" The voice of the Array-Devouring Beast came from below, and his words were full of depression.

"Then what should I do?" Yu Kai couldn't help but get nervous. Facing the tests set by these top powerhouses, he was really unsure and didn't know whether there was any danger or not.

"I don't know either. I didn't know before that this was a temple of inheritance, and it was also the inheritance left by countless powerful people. You better be careful, it's not easy to get their approval." The Array-Devouring Beast spoke in a serious tone, and his words were full of worry about Yu Kai.
