Authority was the only word that Roy could think of currently.

After becoming a demon lord, Roy found that although the difference between demon lords and high-rank demons was only one hierarchy, the feeling they gave him was that they were two completely different beings. Advancing from high-rank demon to demon lord was a qualitative change, so the same logic could apply. The gap between demon lords and demon kings should also be ridiculously large.

Demon lords were called demigods, but demon kings were true gods. As existences like gods, demon kings definitely had some extremely powerful and irresistible power. Roy suspected that this might be the so-called authority.

If his guess was right, and the so-called ‘Gluttony’ ability was Beelzebub’s authority, then he indeed could not easily obtain the power of such authority from the shell.

Fortunately, he was not greedy and did not have the mentality of endless desires. Although he felt that it was a bit regretful, he would not take it to heart after understanding.

Next, Roy and Benia got up and continued to explore this ruin. Since this place was once Demon King Beelzebub’s palace, Roy guessed that there should be a reason why he chose to stay here, and there should be other good things here besides the shell.

Sure enough, in the following exploration, they found a relatively special mineral. This mineral was actually in the space around Roy and Benia, in the rock walls where Beelzebub’s eggs grew!

Benia had only tried to dig out some rocks and found this mineral. They were scarlet crystals sandwiched in the rock. These crystals were very thin and unevenly distributed under the rock walls. Moreover, these crystals seemed to have the ability to store flames and heat. These crystals had absorbed the heat of the magma flowing through the rock walls and then slowly released it, causing the entire underground ruin to have a constant temperature.

Benia recognized this mineral. “This should be flame obsidian, a relatively rare crystal mineral. Don’t look at how the heat released in this crystal is constant. In fact, once you activate it with magic power, the flames and energy stored inside will be instantly released. For demons who are good at using fire magic, it’s very useful. When using fire magic, it can greatly increase the power, and it’s usually used to forge flame weapons and armor!”

Following Benia’s instructions, Roy held a small crystal and infused magic power into it. The next second, his fist erupted with dazzling light, and a layer of blazing flames that burned fiercely covered his entire fist.

This change shocked Roy. He quickly threw the flames away and then looked down at his burnt hand.

Roy had already mastered the flowing brightness flames, so logically speaking, fire magic should not cause much damage to him now. But he did not expect the flames to burn his entire hand black and directly destroy the tissue.

Roy used his other hand to pull off his burnt palm. While regenerating his muscle tissue, he said to Benia in surprise, “These flames are so fierce!? It’s even hotter than Julia’s destruction flames!?”

“It’s just an instant burst of explosive power!” Benia said. “These flame obsidian have been absorbing and storing the heat of magma for thousands of years underground. Although a portion of the heat has been dispersed, they have always stored the remaining portion. The heat accumulated over time is terrifying, and it’s normal for them to exceed the temperature of the destruction flames at the moment of explosion. But these crystals can’t be used as fire seeds to allow demons to obtain new flame power. They can only be used to inscribe runes or engrave magic formations to amplify fire magic. Weapons and armor made of flame obsidian are extremely popular in the Abyss because holding these types of weapons is equivalent to raising the level of your magic attacks and physical attacks, allowing you to better defeat powerful opponents.” “You mean that we can use flame obsidian to forge weapons and armor and then use them to trade with other demons?” Roy understood Benia’s meaning “Well, demons basically don’t have any concept of trade. Even if you want to exchange for souls, you probably won’t be able to exchange for much. But we can trade them for some rare items from other demon lords!” Benia touched the flame obsidian emitting warm energy on the rock wall and said regretfully, “The only problem now is that these flame obsidian aren’t high-grade ores. The crystals are too small, and there’s no way to fuse them into larger crystals. This way, there will be more restrictions when using them to make things.” “It’s probably because of Beelzebub’s insect eggs…” Roy thought for a moment.” Beelzebub left so many insect eggs on these rock walls probably because he wanted to use the heat of the flame obsidian to hatch the eggs… But perhaps because he suddenly encountered something and left, there was no continuous supply of magic power. These insect eggs had an environment of constant temperature, but they couldn’t hatch and eventually turned into fossils.”

“What happened to Beelzebub that he would abruptly leave and leave behind a shell containing powerful magic power and so many eggs? And he hasn’t returned for so long…” Benia asked in puzzlement.

Roy shrugged. “Who knows? With how many years it has been, it’s useless to guess. It may even be just that he has forgotten. After all, to us, figures like Beelzebub are the true tycoons. The shell and insect eggs have immense magic power in our eyes and are a fortune. But to Beelzebub, they’re just insignificant relics, so he abandoned them…”

“I hope so!” Benia was no longer worried about it. “Then, let’s mine the flame obsidian here. Although the quality isn’t high, it’s still a specialty of the territory. We have to find something for those summoned demons to do anyway.”

Roy nodded and did not say anything else. The two of them left the ruins and returned to where Big Black was. Big Black had been waiting obediently. After seeing Roy and Benia return, it carried the two of them back to the surface.

As for the Red Sea Egg, it stayed underground for the time being. There were still many insect egg fossils that the Red Sea Egg had not digested. After some time, Roy should be able to use the Red Sea Egg again.

On the surface, Julia and Fat Tiger were waiting at the entrance of the cave. The earthquake earlier made Julia realize that something might have happened underground. If she had not noticed that it was the magic power pressure that Roy had released, she would have been burning with anxiety. Only after seeing Roy and Benia return safely did she heave a sigh of relief. But then she discovered the increase in Roy’s magic power and asked in surprise, “Darling, what happened? Why did your magic power suddenly… increase so much?! Also, your appearance changed…”

Thus, Roy told Julia what happened underground. When she heard that Roy and Benia had actually found the ruin of Demon King Beelzebub’s palace and found the empty shell that he left behind, even she was shocked.

Back then, Julia had followed Demon King Samael, and she had always been fighting alongside Samael. She had never seen Beelzebub, but she had heard the name of this very famous demon king in many worlds.

There were extremely few cases of demon kings cooperating. It seemed like everyone had the tacit understanding that a king would not see another one. Of course, a demon king like Lilith was an exception. This succubus queen seemed to have affairs with many demon kings…

Julia had never seen Beelzebub before, so she was very curious about his appearance. Unfortunately, the shell had already been absorbed, and she could only imagine it through Benia’s description and Roy’s current appearance.

Someone else had once occupied this territory, which made Roy feel a little regretful. But think about it. The Abyss had given birth to many demon lords over the years, and the probability that others had not occupied the fragment world here was too low. It was impossible to find a completely untouched territory unless he spent a lot of time and patience searching one by one. In comparison, likely only Beelzebub had occupied this territory thousands of years ago, which was already very good.

At least, there were still many things in this territory…

Now, the next step was how to develop the territory. In addition, Roy planned to gradually try to come into contact with other demon lords…
