520: Enter the Demon Tomb

Inside the entrance of the Tian Mo Tomb was a space so vast it was unimaginable.

From the outside, it looked to be only tens to hundreds of kilometers in area.

However, the moment Guo Feng entered, he couldn't see the end of it, and the sky was layered upon layer, easily tens of thousands of meters high.

Up and down, everywhere were pitch-black mountains, large swamps, and pitch-black metal tower-like structures.

At a glance, they were densely packed, so numerous that he couldn't even count them.

"These are all formations, one formation after another, requiring an infinite number of Devils to activate! How powerful a magic treasure must this be? If it were truly activated, it wouldn't be something any single person could do, unless they were a Grand Unity Golden Immortal. My heavens..."

Guo Feng was completely stunned by what he saw inside the Tian Mo Tomb.

This was a magic treasure, capable of being used to slay enemies.

Yet, it was also a place for nurturing Devils, where an endless supply of Devils could be bred.

It was also a massive space, a dwelling that could accommodate tens of billions of people.

Of course, ordinary people couldn't live here at all.

It was too terrifying, too much like the underworld!

"If I subdue this Tian Mo Tomb, not only can I achieve Grand Devil Dao Great Perfection, but I can also possess a supreme treasure. Aside from the Ninefold Haotian Pagoda, no other supreme treasure can compare to this Tian Mo Tomb."

He already understood the value of this Tian Mo Tomb. "I must refine it. The 72 Tianmo King Tombs await me!"

With a thought, he flew towards the sky, carrying a dense demonic aura, heading for those seventy-two incredibly massive 72 Tianmo King Tombs.

From a distance, he looked like an peerless Devil King, and no other Devils noticed anything different about him, as the Grand Devil Dao itself could create Devils.

However, he also knew that once he revealed any other aura, billions of Devils would surely rush over and tear him to shreds.

With so many Devils, even a Heavenly Immortal or Profound Immortal might not be able to handle them.

Before long, he had already surged into the sky, only a few kilometers away from the 72 Tianmo King Tombs.

With a thunderous roar, a massive Devil formation, shimmering with endless demonic energy and swirling with countless Devil runes, began to rotate like a giant millstone.

A powerful formation had activated, and its rotation speed grew faster and faster, forming a massive vortex.

Dozens of mortal rank ninth-grade Devils that were close by were pulled directly into it before they could react, torn apart and exploded alive, transforming into the purest demonic energy that merged into the grand formation.

"What a powerful formation! If my strength were a little weaker, I would have been ground to dust in an instant."

Guo Feng felt the terrifying and immense suction force. Fortunately, his magic power was strong, possessing the strength of nearly three hundred Immortals, and even just by circulating the Grand Devil Dao, he managed to stabilize his body.

However, the suction force continued to increase, seemingly endless.

He understood that this grand formation was meant to block any living being, including other Devils, from entering these Tian Mo King tombs.

He didn't know if it was a test or a defense.

"What if the formation is stronger? I still have to go in."

He also knew that he couldn't waste time; he had to refine this Tian Mo Tomb as quickly as possible and then block the Devil Wormhole.

Otherwise, everything would be too late.

With a thought, he circulated his supreme demonic energy, transforming it into the Grand Devil Protection Light, and like a beam of light, he directly plunged into the grand formation.

The moment he entered, he first felt the terrifying tearing force, constantly depleting his Grand Devil Protection Light, consuming magic power frantically every single second.

Even if he wouldn't be instantly ground to death, if he didn't replenish his energy, he wouldn't be able to last even ten breaths.

However, the space within this grand formation was hundreds of thousands of kilometers wide!

This was a formation with spatial folding; from a distance, it appeared to be only a few kilometers, but inside, it was hundreds of thousands of kilometers.

Moreover, there were endless lightning bolts and black spatial cracks inside.

Teleporting within it wasn't a reckless charge; he had to be extremely careful.

Boom, boom, boom...

He had just resisted the immense tearing force of the formation when black spherical lightning bolts, like a torrential downpour, surged towards him.

He quickly unleashed black Grand Devil Hand Seals with both hands, clashing with the spherical lightning bolts, causing space to explode and lightning to detonate.

Within the entire formation space, it was as if nuclear weapons were undergoing fission, utterly terrifying.

"Fortunately, I have restoration fruit. Although restoration fruit can no longer fully restore me to peak condition instantly, especially my injuries, ten restoration fruits can still restore all my magic power."

Guo Feng couldn't help but secretly rejoice. On one hand, he had to use the Grand Devil Light to resist the tearing force of the formation.

On the other hand, he had to constantly unleash Grand Devil Hand Seals to blast away the pouring spherical lightning.

The consumption of magic power was so immense that an ordinary person would be drained in an instant.

He was also continuously eating restoration fruit, which allowed him to keep moving forward.

Whenever he found an opportunity, he immediately teleported ten thousand li.

The journey was extremely perilous; one misstep, and he would likely be doomed forever.

The difficulty of refining this Tian Mo Tomb was simply inconceivable.

Fortunately, he was currently earning ten thousand spirit stones per second, equivalent to a hundred million in revenue per second.

He could eat restoration fruit as he pleased.

He would teleport whenever he found an opportunity, and when he saw spherical lightning, he would slap it away and detonate it.

Finally, after an unknown number of restoration fruits and an unknown amount of time, he shot out from that hundreds of thousands of kilometers wide area.

As soon as he exited the formation, he felt a sense of exhaustion; it had been too dangerous.

"This formation is too terrifying. I don't know what kind of grand formation it is. Hundreds of thousands of kilometers in area, it's simply boundless. For an ordinary person driving a car, without eating or drinking, at a speed of two hundred kilometers per hour, it would still take half a year. It's too outrageous!"

After coming out, he took a deep breath, adjusted his state, and allowed his mental strength to recover somewhat.

Then, he suddenly seemed to turn to stone.

Before him was a vast, indescribable expanse of tombs and giant projections.

There were seventy-two of them, each tomb estimated to be tens of kilometers in area.

Upon each tomb sat a black giant with a unique physique, cross-legged. They should be the predecessors of the Tian Mo Kings, all in a state of closed-eyed meditation.

However, at a glance, they no longer seemed like Devils; there was no terrifying or negative feeling, but rather a profound, dark divinity.

"Master, these are not Tian Mo King Tombs; at the very least, they are Tian Mo Emperor Tombs!"

At this moment, Li Hunyuan's extremely astonished cry came from within the Qianlong Immortal Sword.

"Tian Mo Emperor?"

Guo Feng was startled; his classification of Devils was still a bit muddled, but he also sensed that the owners of these tombs must have been extremely terrifying existences in their lifetimes!
