Custom Made Demon King

As his strength rose, the number of souls Roy obtained gradually increased, but at the same time, the consumption also increased.

After spending more than 1,400 souls to create his own demon weapon, Roy only had less than 800 remaining souls. Among them, 600 were the high-grade souls that he had obtained from César. Roy used all of these souls to create Magic Energy Growth Potions.

Thanks to the Magic Energy Growth Potions, Roy’s magic power rose much faster than other demons. After turning the 600 souls into Magic Energy Growth Potions, he gained a total of 712 points of magic power.

From the looks of it, these high-grade souls were best used to make Magic Energy Growth Potions.

After his magic power increased to over 1,300, Roy successfully reached the level of a middle-middle-rank demon. Once he doubled his magic power, he would reach the top-middle rank. At that, he would have to advance to high-rank demon.

However, he would not encounter something as good as the César event every time, so Roy estimated that it would take quite some time for his magic power to double.

As his magic power soared, the magic power nodes in Roy’s body increased again, almost covering his entire body. The circulation of his magic power became smoother, and he could release the frost power of Dark Cold from any part of his body.

Even if Roy did not deliberately use his magic power now, he would exhale cold white mist.

Even places he lived often had a layer of white frost on them. Many moss plants had also withered because of the cold aura that Roy released in his daily life.

Roy was a little confused. He thought that his magic power had grown too quickly, and he could not adapt to this power, causing it to spread out unconsciously.

However, Roy was wrong. Everyone’s impression of the Abyss of Hell was that it was all magma and fire, and it was not without reason. That was because it was really difficult to create a cold environment in this world. Among all the elemental demons, frost demons had always been the rarest. As such, most frost demons would think of ways to create a suitable living environment for themselves.

Roy’s cold aura leaking out was because his body instinctively wanted to transform the surrounding environment! As long as Roy stayed in a place for a long time, the magma and flames in this place would fade away over time, and all plants that liked hot environments would die, creating a withering wintry environment.

During this transformation, the frost power of the frost demon would also become increasingly stronger as it continuously resisted the high temperatures. This was why frost demons were the nemesis of most demons. It was precisely because it was difficult for frost demons to survive in the Abyss, which was suitable for using flames, that they trained their frost power to ultra-low temperatures.

When Roy finally realized this, he allowed the cold aura to disperse reely. He also specially created a thermometer through the system to measure the temperature of his frost power.

He discovered that the lowest temperature of frost power he currently controlled reached about minus seventy degrees Celsius, which was almost the temperature of Earth’s South Pole.

This low temperature was only the temperature when he released magic power slowly. Once he unleashed his full power, the temperature would be even lower.

Roy began to look forward to whether or not he could achieve a low temperature like absolute zero in the future. Hmm… Perhaps it was not possible because absolute zero was the theoretical limit of temperature. The frost demon bloodline might not reach this level, but it did not matter. He could perhaps define and create it through the system.

Although Roy guessed that the number of souls consumed to define absolute zero would be absolutely terrifying, this was still a thought, wasn’t it?

One of the benefits of Roy’s transformation of his living environment was that very few demons were willing to go near his residence. Because the temperature here was abnormal, demons who liked heat would subconsciously avoid it, and Roy had stopped many enemies who coveted his territory.

In other words, in the future, only he would be the one to break open the doors of other demons, and no other demons would break open his doors…

Fortunately, Roy’s cold aura did not lower the temperature of the environment of his residence without restriction. Otherwise, Fat Tiger would have been in trouble. Although he had an ice-attribute head and could withstand the cold, the other two heads were fire or poison, so Fat Tiger was always sleepy when he was beside Roy.

Roy had no choice but to let Fat Tiger go out and play by himself. After fusing with hellfire, ordinary middle-rank demons were no match for him…

Days passed. Other than hunting souls, Roy usually stayed in his residence to design plans.

Among the rewards Edrach had given, there were three fallen souls. Roy used these three souls to complete a dynamic skill design. Considering that he did not have long-range attacks, Roy naturally designed a long-range skill.

Roy named this skill Icebound Strike, and it was released using the help of his demon weapon, Frostmourne.

While waving Frostmourne, Roy injected magic power into it and used the process of swinging his sword to release a crescent-shaped frost beam. The frost beam flew very quickly, and once it hit the target, it would immediately freeze the target.

Depending on the amount of magic power infused into the skill, the flying distance could also change. But generally speaking, fifty points of magic power could let it fly about three hundred meters away, which made it a low-consumption practical skill.

In addition to this skill, Roy also redesigned his demon wings. He added some patterns of demon text and symbols on his demon wings, and these patterns were meant to carry the Halo of Fear.

Roy had found the fear effect of the Eye of Nightmares really useful, so he planned to expand the range of this fear effect. When the demon symbols on the demon wings lit up, it meant that he had activated the Halo of Fear…

After completing these two design plans, Roy’s souls were completely exhausted. However, a month had passed, and Roy’s cooling down period was almost over, so he could go back to another world again to obtain souls.

However, before Roy could move, Fat Tiger returned from playing outside and brought back something strange.

It was a black stone that looked like a lava rock formed after magma cooled. When Roy picked up the stone, he found that there was a shiny gold ore inside the cracked stone.

“This is… gold?!” Roy was a little surprised. He swiped his claws, peeled off the outer layer, and discovered that it was really a piece of gold!

The shape of the gold was very irregular. It had a lot of rough edges and looked like a naturally-formed gold nugget. But the strange thing was that this piece of gold not only had a shiny golden color in Roy’s eyes but also had faint black gas mixed in it!

However, Roy did not discover any special magic power in the gold.

“Strange. What is this black gas?” Roy was confused and asked Fat Tiger, “Where did you find this thing?”

Fat Tiger barked at Roy, turned around, and ran. Roy followed behind as Fat Tiger led him a long distance. They left his territory and finally arrived at a strange mountain range.

This mountain range was full of protruding sharp black rocks, as though the spurs of the mountains were sticking out. Fat Tiger led Roy through these sharp rocks until they reached a cave entrance halfway up a mountain.

The entrance was not big. Fat Tiger easily drilled into it, but Roy had to retract his wings and shrink his body. After entering the tunnel, he walked for a distance and found a golden light in front of him.

When he reached the exit, Roy was stunned!

It was an extremely large empty chamber inside the mountain. What was visible were the sharp rocks that covered the top and the ground of the chamber. But among these rocks, there were a lot dotted with golden light!

Gold! All gold! It was actually a gold mine!

All of the gold here was basically in the form of gold nuggets. They were wrapped in thick or thin rock layers, and the gold that was inadvertently revealed had already dyed the cave golden. It was apparent just how many there were.

To demons, gold was worthless because demons did not use gold as currency at all, so even if there was a gold mine here, no demons would come. Therefore, the gold mine could be considered well-preserved. Roy was naturally dazzled when he saw so much gold.

Damn it. If I had discovered such a gold mine in my previous life, wouldn’t that have been great?

Roy could not care about anything else. He quickly asked Fat Tiger to help him dig out the gold ore. One dog and one demon worked for more than an hour and dug out about a ton of gold ore.

In order to get this gold ore out, Roy had to widen the cave entrance they came in. Finally, he used the system to create a large woven bag to carry the gold ore out.

After returning to his residence, Roy had Fat Tiger carefully spit out hellfire to smelt the gold ore.

In the end, he got a few large pieces of irregularly-shaped gold ingots that weighed more than a total of five hundred kilograms.

However, what confused Roy was that after putting these gold ingots together, the black gas that he saw emitting from gold became even more intense.

“What’s going on? Why does all the gold have this black gas?” Roy was puzzled. “This black gas shouldn’t be something ominous, right?”

Roy did not know that the gold he had dug had a specific name in the Abyss.

Demon gold!

If this demon gold were taken to other worlds, the people of the other worlds would not be able to see the black gas. Only demons could see it.

This black gas was actually a special power. Demons were unaffected, but once the people of other worlds obtained this demon gold, something would be continuously sucked away from them by the black gas… Luck!

Demon gold, also known as the gold of misfortune!
