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

Since entering this tomb, everything that has happened has been strange.

Whether it's the secret manuals left by the Underworld Emperor, the legends of those demonic cultivators, or the intelligence from the righteous path, they are all far removed from the true situation in this tomb.

So much so that Lin Feng couldn't figure out what exactly had happened.

"There's no Yin Pill, but there is a Myriad Spirits Banner. I wonder what the Underworld Emperor's purpose is."

After saying that, Lin Feng fixed his gaze on Wanlingqi.

Without any spiritual power being activated, simply by gripping the flagpole with his hand, a surge of resentment that went straight to the heart made Lin Feng's heart tremble.

However, to Lin Feng's surprise, he did not sense the main soul on the Myriad Spirits Banner.

This means that although the Myriad Spirits Banner contains extremely strong power, it is essentially an unclaimed object.

Since that's the case, Lin Feng naturally wants to try and see if he can control it.

"call!"

Lin Feng took a deep breath and muttered to himself.

"Surrounded by formidable enemies, survival is uncertain; we have no choice but to take a gamble!"

After saying that, Lin Feng took out the jade pendant and began to try to inject spiritual power into the Myriad Spirits Banner.

Spiritual energy surged from Lin Feng's dantian and continuously flowed into the Myriad Spirits Banner.

However, the Myriad Spirits Banner was like a bottomless abyss, devouring everything without any control over Lin Feng.

"Fine, let's try using the remnant soul of the Underworld Emperor again!"

Lin Feng summoned the remnant soul of the Underworld Emperor again, and used it as a medium in an attempt to control the Myriad Spirits Banner.

It moved!

As the power of the remnant soul of the Underworld Emperor entered the Banner of Ten Thousand Spirits, the originally chaotic and random resentment within it began to circulate in a regular manner.

A vast aura of resentment, carrying with it boundless oppressive power, spread outwards.

This space was not large to begin with, and this oppressive force had nowhere to go, so it crashed around in the confined space. If it weren't for the two puppets protecting him, Lin Feng would probably have been injured first.

"This! Such immense power!"

"My cultivation is too weak. Even if I obtained a magic weapon of this level, I would not be able to control it accurately."

"Even so, it also proves that this thing is indeed ownerless, otherwise it would be impossible for me to control it."

"We need to be careful and try again to see if the Myriad Spirits Banner has any other effects!"

Lin Feng didn't understand why the flag left behind by the Underworld Emperor had become ownerless, but since it had fallen into his hands, he should accept it. Otherwise, it could only be called a celestial destiny.

This Myriad Spirits Banner has been nurtured in the tomb for a thousand years, so its power is undoubtedly formidable. As the core of the entire tomb's formation, it should also have some other effects.

Lin Feng, wanting to survive, could only place his hopes on the Myriad Spirits Banner.

Thinking of this, Lin Feng summoned both remnant souls of the Underworld Emperor.

Under the combined manipulation of the two remnant souls, Lin Feng finally managed to figure out the formation under the Myriad Spirits Banner.

It turns out that all the yin energy in the entire tomb, including the isolated space, was controlled by this Myriad Spirits Flag.

This means that as long as Lin Feng is willing, he can use the power of the Myriad Spirits Flag to open the entrance to the tomb.

Of course, he could also open the connection between this small space and the tomb.

Having confirmed this ability, Lin Feng couldn't help but sneer.

"These old bastards want to use me as a sacrifice, then I'll lure them into a trap!"

After saying that, Lin Feng began making his arrangements again.

Meanwhile, deep within the tomb, Venerable Xuanming and the others were already getting impatient.

According to their plan, Lin Feng was thrown into the small space where the Yin Dan was located, and he should be devoured soon.

But after waiting for a long time, they didn't hear a sound. For a moment, these old guys couldn't help but start muttering to themselves again.

"Has something gone wrong again? Why is there still no news?"

"That Yin Pill requires a living being's blood sacrifice. Lin Feng has already gone in, so he should have been devoured by now. Why hasn't there been any reaction yet?"

If it were someone else who was sacrificed, they wouldn't be in a hurry.

Having dealt with Lin Feng for so long, they still didn't know if he had any other treasures or any other extraordinary encounters.

Fearing that things might change if they waited too long, Venerable Xuanming stepped forward and addressed the others.

"The place where the Yin Pill is stored is a combination of multiple overlapping spaces. If the physical body enters, the pressure will be immense. But we can't just wait here idly. I think we should work together to protect me, while I send a wisp of my divine sense in to investigate."

These old fellows all had their own ulterior motives, and they wouldn't take any risks. Therefore, Venerable Xuanming had no choice but to compromise and ask everyone to work together to protect a wisp of his divine consciousness. Without having to bear any risks, these people agreed.

"Okay! Let's do it this way!"

Helpless, Venerable Xuanming could only separate a wisp of his divine thought and ask everyone to release their spiritual power to enhance it, preparing to enter the space where Lin Feng was to explore.

However, at that moment, the small space and the entrance to the tomb suddenly shook, and the previously isolated spaces were connected.

"This! Could it be that the Yin Pill has already devoured Lin Feng?"

"Why is there no reaction at all?"

Filled with doubt, the group walked to the entrance. After confirming that there was no danger, they quickly agreed to go in and take a look.

"Gentlemen, the spatial turbulence here has disappeared. We should go and check it out as soon as possible."

"To prevent any unforeseen circumstances, we should all stand together!"

After reaching an agreement, everyone entered the entrance together. After passing through a dark and chaotic area, they entered the small space where Lin Feng was.

"Lin Feng!"

As soon as they entered, they saw Lin Feng sitting on the coffin.

"You're still alive?!"

Lin Feng looked at Venerable Xuanming and the others, and said with a cold smile.

"You're all still alive, so how can I die?"

Venerable Xuanming stepped forward and said with a gloomy expression.

"Lin Feng, where's the Yin Pill?!"

Although Venerable Xuanming hated Lin Feng to the core, he knew very well that everything he did was for the Yin Pill.

There will be plenty of opportunities to take revenge on Lin Feng later; right now, we must find the whereabouts of the Yin Dan.

The old men approached the coffin, yanked open the lid, and found it empty; there was nothing inside.

They instinctively assumed that Lin Feng must have taken the Yin Pill, and they all questioned him.

"Lin Feng, what exactly is going on? Where is the Yin Pill inside?!"

"Hand it over right now!"

Lin Feng smiled calmly, a hint of sarcasm in his eyes.

There was no Yin Pill in here to begin with.

"From beginning to end, all the information you received was completely wrong!"
