The ranged attacks instantly unleashed by those King Level Demons failed to harm Lu Cang in the slightest.

As for the Lord Level attacks, Lu Cang blocked them with ease.

Earth Fire, Ten Thousand Vines, Thorns, Stone Arm, Crushing Spike Wall...

Sea of Fire, Ice Burst, Flame Wave, Multi-chain Thunderbolt...

The greatest feature of Tier Two Spells is the Elements.

Offensive and defensive Magic based on various Elements.

Magic manifested from thin air, sweeping through one King Level Demon after another. Everywhere it passed, it was a guaranteed kill.

At the same time, a Sea of Fire carpeted the ground, and various other large-scale spells quickly cleared out the small fry on the field.

In fact, even without the other Magic, just casting a Sea of Fire in front of him from a Sacrifice of 100 souls was enough. Tier Three Lords were completely unable to get close; they would die just by walking through it.

These small fries were basically just delivering souls to Lu Cang.

Lu Cang wasn’t as fast as Chi Cheng, taking about 40 seconds to deal with the thirty-three King Level Demons.

He didn’t move a single step from start to finish.

Even when a few tenacious ones managed to charge over, Lu Cang forcibly pushed them back with Rejection Wind Roar, Resistance Water Ring, Repulsive Tide, Wandering Shadow Swamp, Solidifying Foot Mud Swamp, and Extremely Resilient Rope Vine.

No matter what tricks they tried, they couldn’t get close. The most damage they could inflict on Lu Cang was through sonic and Spirit-based suppression.

Unfortunately, the Demons that could launch Spirit or sonic attacks were the first ones Lu Cang took out.

The ones that survived a few seconds longer posed no threat.

Chi Cheng: "Haha, not bad."

"You’ve got my style from back in the day." As Chi Cheng said this, he felt a little uncertain.

’Back in my day... did I really have this kind of style?’

Chi Cheng mumbled to himself as he went to collect the corpses.

Chi Cheng couldn’t be bothered to collect the Lord Level Demons.

It was a waste of time to spend forever collecting something worth only a dozen or so Gold Coins.

Only the King Level Demons, with a fifty-fifty split, would net a harvest of about one thousand each.

Thirty-three of them meant a profit of thirty-three thousand Gold Coins.

Lu Cang was quite satisfied with this fifty-fifty split.

He could handle these Tier Three Demons himself, but if he ran into a Tier Four Nation Destruction Level one, he would still need Chi Cheng’s help.

As for souls, he harvested 4,122.

’I Sacrificed 5,100 souls... Looks like I’ll have to kill more ant-type Demons. These ones look imposing when they charge over in a swarm, but their numbers aren’t actually that high. They just look numerous because they’re so big.’

’I’ll have to experiment more.’

"Chi Cheng, about my ability to alter Dungeons..."

"I know, I know. I won’t go blabbing."

"I understand this kind of thing."

Lu Cang nodded. "Mm, thank you, Brother Chi Cheng."

The two of them continued on, looking for Dungeons to perform Sacrifices.

As expected of a famous adventurer’s paradise, huh? You could basically find a new Dungeon after walking just a short distance. They were truly endless.

They arrived before a Tier Three Dungeon.

Sacrifice — 10,000 Souls

A Tier Three Dungeon after a Sacrifice of ten thousand souls yielded fifty Tier Three King Level Demons...

’The number of small fries doesn’t seem to have increased much.’

Lu Cang handled this Dungeon by himself as well.

’The soul-collecting specialization is really a huge help. It even helps me keep count, letting me know how many monsters I’ve killed.’

There were 50 King Level ones.

There were 122 Lord Level ones.

The remaining elite and normal cannon fodder were basically the same, totaling only about six thousand or so.

’A Sacrifice of one thousand souls resulted in 10 King Level Demons.’

’A Sacrifice of five thousand souls resulted in 33.’

’A Sacrifice of ten thousand souls only gives 50?’

’The cost-effectiveness is getting worse and worse.’

...

After leaving that Dungeon, they went on to find four more Tier Three Dungeons.

Lu Cang tried Sacrificing six thousand, seven thousand, eight thousand, and nine thousand souls.

He was strictly controlling the variables.

His hypothesis was more or less verified.

Indeed, the more souls he Sacrificed, the smaller the increase in the number of powerful Demons.

After these few runs, he thought.

"Oh! Another Tier Four Dungeon!"

Chi Cheng was visibly excited!

Next, they tried a Tier Four Dungeon.

This time...

Sacrifice — 50,000 Souls

The Sacrifice of fifty thousand souls still made Lu Cang wince. Farming souls wasn’t exactly easy.

But the thought that a single Tier Four Nation Destruction Level Demon was worth over 200,000 Gold Coins quickly cheered him up.

"Brother Chi Cheng."

"This time, can you let me try my hand against the Nation Destruction Level Demon?" Lu Cang asked.

Over the past half-month, he had already fought against Tier Four King Level Demons.

Using only his Mage Class, he could indeed kill a Tier Four Monarch, but as for a Nation Destruction Level... Lu Cang had no reference.

"That’s no problem," Chi Cheng agreed readily.

Lu Cang continued, "If I get into danger, I’ll have to ask Brother Chi Cheng to protect me."

This was the very reason he had wanted to travel with Chi Cheng today.

Lu Cang wanted to experiment with Sacrificing to Dungeons.

But experimenting wasn’t about being reckless; he had to prepare a backup plan to guarantee his own safety.

He had only read about Nation Destruction Level Demons in records, never encountered one. Without fighting one, he wouldn’t know its actual strength.

Moreover, before the actual Sacrifice, Lu Cang had no idea what his Sacrifice would turn the Dungeon into.

Everything he knew was the result of today’s experiments.

’What if the Dungeon’s exit disappears? What if it summons a Demon that surpasses the Dungeon’s original tier? What if a Nation Destruction Level Demon appears and I can’t defeat it? What if I can defeat one, but there are many of them...’

All these unknown dangers required a fail-safe strategy.

If Chi Cheng hadn’t come today, Lu Cang would have chosen to abandon the experiment. He wouldn’t gamble with his own life.

They stepped into the Dungeon.

The sight before him was like a continuous mountain range.

Nation Destruction Level Demons were truly enormous.

It was like looking at a fifty-meter-tall giant wall blocking his path, its four sturdy legs shaking the earth.

’Even if my Punching Pillar or Ice Shuttle Magic hits it...’

’...it would probably be like a mosquito buzzing around.’

And Demons like this...

There were a full ten of them right before his eyes.

Fifty thousand souls had turned into ten Tier Four Nation Destruction Level Demons...

There were also seventeen Tier Four King Level Demons.

Lu Cang swept his gaze over them.

He immediately felt the Elements around him rioting!

BANG!

Using Wind Roar and Tuan Spring, Lu Cang launched himself into the sky.

The ground turned scorching, blood-red!

The area in a five-hundred-meter radius, with his former position at its center, had become a field of pure crimson!
