Only a handful out of the dozens who had entered the tomb remained alive. Their cultivation was generally high, allowing them to resist the invasion of the yin energy.

"Since all of you are going to die anyway, you might as well help me!" The ghost immortal broke free from his fight with Tang Yang and charged at the other immortals on the ground after Yin energy invaded their bodies.

A ghost claw pierced their bodies and extracted the energies within. This allowed the ghost immortal's aura to rise, advancing to the ninth-level Heavenly Immortal Realm.

The number of cultivators decreased even further. Only Liu Wuxie, Tang Yang, Deng Jun, Shi Minghuo, and the ghost immortal remained. The ghost immortal had used only a few breaths to advance successfully to the ninth-level Heavenly Immortal Realm.

Right at this moment, the Gloomwood and the Yellow Springs Water charged toward Liu Wuxie, releasing a tide of yin energy that froze the surrounding space. Even breathing became difficult as the air began solidifying.

A faint smile appeared at the corner of Liu Wuxie's lips. He had been wondering how he should collect the treasures, and they had delivered themselves to him. This instantly saved him a great deal of time.

The Sky Devouring Divine Cauldron released a powerful suction force. The black hole began spinning like a massive vortex, exerting a terrifying pull, and the Yellow Springs Water and the Gloomwood could not withstand it as they flew into the cauldron.

White beads hovered above the cauldron. After the cauldron devoured the three treasures, they began fusing and concentrated further under the cauldron's suppression.

Each white bead contained the power of the Gloomwood, the Yellow Springs Water, and the Limitless Ice.

Deng Jun finally realized the gravity of the situation. "Stop him! We can't allow him to succeed!"

He had initially planned to use the power of the Gloomwood and the Yellow Springs Water to kill Liu Wuxie. But the situation had reversed, allowing Liu Wuxie to use the three treasures to break through to the fifth-level Heavenly Immortal Realm.

Deng Jun and Shi Minghuo charged over, launching a pincer attack to stop Liu Wuxie from refining the treasures.

The ghost immortal looked at Liu Wuxie before turning to the massive coffin. He immediately gave up attacking Liu Wuxie and charged toward the coffin.

Tang Yang tried to stop him, but by the time he reacted, it was already too late. The ghost immortal had already appeared before the coffin.

The ghost immortal attacked with his ghost claw, grabbing one side of the coffin and trying to pry it open. He exerted a great deal of strength, but the coffin stood unmoving. After all, how could he possibly open such a heavy coffin lid with his strength alone?

"Ghost Immortal, we can open the coffin together after we kill Liu Wuxie!" Deng Jun yelled, urging the ghost immortal to come over and help them deal with Liu Wuxie.

The ghost immortal only hesitated briefly before charging toward Liu Wuxie.

"Senior Tang, step back!" Liu Wuxie said. He knew Tang Yang could no longer take part in the upcoming battle.

He left the refinement of the Gloomwood and the Yellow Springs Water to the Sky Devouring Divine Cauldron while he focused entirely on the fight. The joint attack did pose some trouble for Liu Wuxie at first, but only because he had to divert part of his attention to collecting the treasures.

There was barely any mist left in the surroundings, with most of the three treasures devoured by the Sky Devouring Divine Cauldron. Liu Wuxie could now fight without any restraint.

The moment he attacked, he resorted to the Divine Eternal Fist, imprisoning Shi Minghuo and Deng Jun in place. Then again, Liu Wuxie's combat strength had undergone a drastic transformation after his breakthrough.

He had yet to fully absorb all of the Snowcloud Fruit's energy, with some of it still lingering in his body. He drew upon that remaining energy and fused it into the Divine Eternal Fist.

The mostly restored Fire Ancestral Talisman also began channeling its terrifying fire-attribute energy into the Divine Eternal Fist.

The entire chamber lit up as bright as day. A terrifying surge of fire-attribute energy gushed out and suppressed the ice-attribute energy. The moment the ghost immortal got close, the wave of energy sent him flying, leaving him in shambles.

"This is impossible! You're only a fourth-level Heavenly Immortal. How can you possibly possess such heaven-defying combat strength?!" Deng Jun yelled. He could no longer maintain his composure after realizing Liu Wuxie's combat strength was comparable to that of high immortals.

Even in the celestial realm, Liu Wuxie could be considered a monstrous prodigy based on his talent.

"You garbage can all die!" Liu Wuxie roared. He had no intention of sparing anyone, regardless of whether it was Deng Jun, Shi Minghuo, or the ghost immortal. They all had to die. From the moment the ghost immortal attacked him, Liu Wuxie had already marked him as a dead man.

When the Divine Eternal Fist came crushing down, the entire chamber began shaking violently. Even the enormous coffin trembled slightly as a narrow opening appeared in its lid.

The punch struck the ghost immortal's chest, and he exploded into a messy blood splatter upon contact. The Sky Devouring Divine Cauldron then devoured him.

Next came Deng Jun, who also could not withstand the force and exploded.

By the time everything came to an end, only two people remained in the chamber. Deng Jun, Shi Minghuo, and the ghost immortal had all died.

Deng Jun and Shi Minghuo had no remains left. Liu Wuxie had made sure to sever their past and present to prevent any possible leakage of information from the mortal realm.

Only the immortal's avatar projection of the Grand Unity Sect remained a concern. No one had seen him yet, which probably meant he had returned to the celestial realm. Fortunately, the Grand Unity Sect's avatar projection most likely did not belong to the same group as Gan Xingzhou's.

With a loud rumble, the black hole vanished. All the white beads flowed into the desolate world, allowing Liu Wuxie's cultivation to race toward the fifth-level Heavenly Immortal Realm.

Tang Yang could only watch with envy from the side. He had witnessed Liu Wuxie go from the first to the fifth-level Heavenly Immortal Realm in just a few days. Meanwhile, he had spent countless years cultivating to his current level. This made him look pathetic in comparison.

"Senior Tang, prepare to make a breakthrough!" Liu Wuxie injected close to a hundred white beads into Tang Yang's body. He naturally remembered Tang Yang's kindness in helping him hold back the ghost immortal earlier.

Moreover, the energy in the three treasures was too massive for Liu Wuxie to absorb by himself.

"Thank you!" Tang Yang said gratefully.

As soon as the white beads entered his body, he immediately broke through his bottleneck and sped toward the eighth-level Heavenly Immortal Realm.

Over the years, those around Liu Wuxie had benefited greatly, including the Heavenly Dragon Sect's elders.

Time slowly passed, and their auras finally calmed down after two hours. Liu Wuxie had successfully reached the fifth-level Heavenly Immortal Realm, while Tang Yang had advanced to the eighth. When Liu Wuxie and Tang Yang exchanged a glance, they both smiled broadly.

Liu Wuxie found more than ten thousand immortal stones inside Deng Jun's and Shi Minghuo's interspatial rings. But aside from immortal stones, there were no other treasures. It seemed they had likely left their other belongings in the celestial realm before descending.

"Wuxie, what should we do now?" Tang Yang asked, now following Liu Wuxie's lead. He knew he would have died without Liu Wuxie.

"Open the coffin," Liu Wuxie said. He wanted to know who was in the coffin. The tremor from the earlier battle had already forced a small slit in the lid.

"Forgive me for my actions. I have no intention of offending you," Liu Wuxie said. He bowed to the coffin, as the dead deserved respect, regardless of their identity. Opening the coffin of the deceased was disrespectful, no matter how one looked at it.

However, with formidable enemies ahead, Liu Wuxie had to do everything possible to raise his cultivation. In such extraordinary times, he could only resort to extraordinary means.

Tang Yang also stepped forward immediately and bowed in respect.

Only then did Liu Wuxie walk over to a corner of the coffin and send his divine sense inside. After verifying that there was no danger within, he worked with Tang Yang to slowly open the coffin.

The coffin was incredibly heavy, and the two expended considerable effort before they managed to open it, revealing the interior.

"This is strange. Why aren't there any corpses inside?"

Forget the corpses; there wasn't even clothing for a cenotaph burial. Everything reeked of strangeness, and Liu Wuxie only saw a few books, leaving him confused.

As Liu Wuxie reached out to retrieve the three books, Tang Yang tactfully stepped back. The latter had already made a breakthrough in his cultivation. He was already satisfied with his harvest, and he knew that the treasures in the coffin had nothing to do with him.

A person had to know contentment and avoid greed. As someone who had lived for hundreds of thousands of years, Tang Yang naturally saw through matters like this more thoroughly than most.

While he knew Liu Wuxie would likely agree if he asked to share the treasures, his status would inevitably drop to the lowest point in Liu Wuxie's heart.

When Liu Wuxie opened the first book, it did not contain any heaven-defying immortal art but a biography. He read it for more than ten minutes before imprinting all the contents into his mind.

After closing the book, Liu Wuxie mumbled, "I didn't expect Madame Mystic Yin to be buried here."

"Wuxie, who's Madame Mystic Yin?" Tang Yang asked.

"A legendary woman," Liu Wuxie replied. He closed the book and did not explain in detail, as those were secrets of the celestial realm. It would not benefit Tang Yang to know too much.

Back then, everyone in the celestial realm knew that Ning Chou had pursued Madame Mystic Yin, but fate kept playing tricks on them, and they never ended up together.

When Liu Wuxie flipped through the second book, it contained Madame Mystic Yin's cultivation insights and records of some immortal arts. But the power of these immortal arts was ordinary, roughly on par with the Divine Eternal Fist.

"There are several immortal arts recorded in this book. You can take a look and learn as much as you can," Liu Wuxie said, tossing the book over to Tang Yang.

Tang Yang received the book as if it were a treasure and immediately flipped through it. He only chose one and did not even look at the others.

Seeing this, Liu Wuxie nodded in satisfaction. It was not that Liu Wuxie was being petty with the immortal techniques, but that Tang Yang would not be able to digest them if he bit off more than he could chew. It would already be impressive if Tang Yang could master one immortal art.

As the saying goes, a jack of all trades is a master of none. For most ordinary people, devoting all their effort to one immortal art was better than dividing their attention between two. Moreover, time was limited, and unlike Liu Wuxie, Tang Yang lacked the Heavenly Dao Book, making it impossible for him to absorb its contents in such a short time. Thus, devoting all his attention to one immortal art was undoubtedly the most practical choice for Tang Yang.

Then again, how many people could restrain their temptation and greed? Most people who obtained such a book would wish they could memorize everything inside. But greed was the greatest sin among cultivators, and only those who could keep their greed in check could become powerful experts.

When Liu Wuxie picked up the last book, his eyes shone brightly when he saw the four characters on the cover.

Liu Wuxie looked at the book with excitement. "The Divine Mystic Yin Needle! It's actually the cultivation manual for the long-lost Divine Mystic Yin Needle!"

Ordinary immortal arts could not catch his eye, and only top-tier immortal arts could draw his attention. Since he could not use the immortal arts he had mastered in his previous life, as doing so would expose his identity, he had to forget everything from the past and start over. That would be especially true once he ascended to the celestial realm. He could not afford to reveal anything about his previous life there, or he would face endless pursuit.
