I, a centenarian, sweep through the gates of immortality.

Venerable Xuanming's hatred for Lin Feng was almost overflowing.

Before the person even reached Lin Feng's side, a surge of powerful spiritual energy swept towards him.

If it weren't for the two puppets protecting him, Lin Feng would probably have been crippled on the spot.

As Venerable Xuanming and the others drew closer, Lin Feng couldn't help but gasp.

"If they fall into their hands, who knows how they'll be tortured."

Lin Feng glanced at the spatial rift, gritted his teeth, and quickly made a decision.

"I'd rather be torn to pieces by the spatial turbulence than suffer their torment!"

Having made up his mind, Lin Feng didn't hesitate for a moment and jumped down.

The spatial turbulence was so intense that Lin Feng's physical body was completely unable to support it.

Left with no other choice, he took out the jade pendant and used the power it had absorbed during this time to protect himself, and then summoned the little Pixiu.

"Little guy! Help me!"

The little Pixiu, clinging to Lin Feng's waist, was also in great pain from being torn apart by the spatial turbulence. However, the divine beast's body was far superior to Lin Feng's, and it managed to withstand the strain, even having the energy to heal Lin Feng.

With the combined effect of the jade pendant and the small Pixiu, Lin Feng finally survived. He felt his body falling rapidly, struggling and turbulent for a long time before finally landing.

"This is?"

Lin Feng looked around blankly. He was shocked to find that the space he had fallen into was extremely small. It was pitch black all around, and he couldn't see anything. The only thing he could see was a dark blue coffin in front of him, and billowing yin energy was constantly seeping out from the cracks in the coffin lid.

"Could this be the coffin of the Underworld Emperor?"

"Legend has it that after the Underworld Emperor passed away, his body was completely destroyed in order to preserve the Yin Elixir, wasn't it?"

"And what's inside this coffin?"

Despite having countless doubts, Lin Feng dared not open the coffin rashly.

He thought the coffin had been turned around several times, but then he discovered that there was actually a bone-revealing mirror placed directly in front of it.

Looking closer, Lin Feng discovered that he could actually see through the mirror.

They observed everything that happened inside the entire tomb.

He saw that the disciples of those prestigious sects were gathered together and receiving treatment.

Meanwhile, Venerable Xuanming and the others were gathered around the spot where Lin Feng had just disappeared, discussing the matter animatedly.

A cold smile played on Venerable Xuanming's lips as he spoke with a smug expression.

"Hmph, Lin Feng finally got in!"

"That old scoundrel, the Underworld Emperor, thinks his scheme is brilliant—how laughable!"

Upon hearing Venerable Xuanming's words, Lin Feng's heart tightened.

Was it all part of their plan that I was forced to jump in?

At this moment, Liu Yi of the Fengtian Sect laughed.

"The Yin Gate was placed outside, and nine bone-revealing mirrors were left behind, clearly indicating that they were waiting for someone to open the grave!"

"This is clearly a conspiracy; they're actually waiting for us to fall into their trap. How ridiculous!"

Venerable Xuanming said coldly.

"According to the Underworld Emperor's original plan, all of us would become sacrifices for his Yin Pill."

"Only Nascent Soul experts like us can help him achieve perfect Yin Core."

"Unfortunately, he miscalculated; we won't fall for it."

"Next, the Yin Core will only devour Lin Feng. However, Lin Feng's cultivation level is insufficient to perfect the Underworld Emperor's Yin Core. We can take advantage of the incomplete process of devouring Lin Feng to take the Underworld Emperor's Yin Core out!"

"Once we leave this isolated space, the Underworld Emperor's Yin Core will be at our disposal."

"Haha, this is truly heaven's help!"

"Originally, obtaining the Yin Pill would have required paying a heavy price, but unexpectedly, Lin Feng actually killed the Underworld Emperor's possessor and now possesses two remnant souls of the Underworld Emperor. This has saved us a lot of trouble!"

Everyone agreed, and at the same time turned to look at the small space where Lin Feng had just jumped down.

"To have obtained the Yin Pill, Lin Feng's death can be considered worthwhile!"

Because the space was completely folded, they couldn't see Lin Feng clearly, but Lin Feng heard their words perfectly.

At this moment, Lin Feng's face was ashen, and he was drenched in cold sweat.

He originally thought that since the appearance of the Tomb of the Underworld Emperor, he had had many extraordinary encounters, which were all due to the opportunities provided by Heaven.

Unexpectedly, even his absorption of the remnant soul of the Underworld Emperor was within the calculations of those old guys.

"What a clever scheme!"

Lin Feng felt a little desperate. If what those old guys said was true, wouldn't he be doomed?

He can't get out now, and even if he did, Venerable Xuanming and the others wouldn't let him go.

If he stays here, the Yin Elixir in this tomb will devour him.

Either way, we're doomed!

"What should I do?"

"The Yin Elixir in this coffin will devour me. Am I just supposed to surrender?"

Although Lin Feng felt desperate, he was never one to sit idly by and wait for death.

Since the Yin Pill is destined to devour Lin Feng, why doesn't Lin Feng take the initiative to attack?

Lin Feng still has the jade pendant in his hand. Perhaps the jade pendant can absorb the Yin Pill in reverse!

"There's no other way but to try again using this jade pendant."

"Since embarking on the path of immortality, this jade pendant that I have always carried with me has never failed me."

"Let me show you what I'm capable of today!"

Lin Feng was actually feeling uneasy, after all, it was the Yin Pill of the Underworld Emperor. He was unwilling to risk such trouble unless absolutely necessary.

But he has no other choice now.

Lin Feng suddenly walked up to the coffin, slapped it hard with his right hand, and knocked the coffin lid off.

A torrent of black evil energy surged from the coffin, like a black river, instantly engulfing the entire space.

Lin Feng, resigned to his fate, forcefully dispelled the black demons before him and stared intently into the coffin.

He wanted to find that Yin Pill.

However, no matter how long Lin Feng groped around in the coffin, he couldn't find any Yin Pills. Instead, he grabbed a piece of wood.

"wood?"

A piece of wood as thick as a human arm was grabbed by Lin Feng and lifted high. In the black mist, a large flag was emitting black mist.

"What! What is this?!"

"There's no Yin Elixir! All the Yin energy has gathered on this flag!"

Only then did Lin Feng see the three large characters on the flag.

The Banner of All Souls!

Although Lin Feng was not a proper demonic cultivator, he had taken a look at the secret manuals left behind by the Underworld Emperor during this period.

I have also gained some understanding of things like the Ten Thousand Soul Banner and the Ten Thousand Spirits Flag.

This is a magical artifact used by demonic cultivators. It is nourished by the spirits of those who died unjustly, making it extremely insidious. At the same time, it contains immense power and is a magical artifact that many demonic cultivators pursue throughout their lives.

However, Lin Feng couldn't understand why the Underworld Emperor would leave this magical artifact behind.

According to previous predictions, the Underworld Emperor's plan to nourish the Yin Pill was aimed at achieving rebirth.

But what use is it for him to keep this magical artifact now?

Even if this magical artifact has been nourished to its fullest extent, it is already dead.

With these doubts lingering in his mind, Lin Feng muttered to himself.

"That's so bizarre!"
