To be honest, the ability displayed by the clone really exceeded Roy’s expectations.

Logically speaking, this clone was cloned from one of Roy’s arms. Even if he had abilities, he should have displayed the abilities of his frost demon bloodline. But Roy did not expect that just an empty shell of Beelzebub would completely suppress his bloodline in the clone, causing the abilities displayed by the clone to be vastly different from his.

Even to the extent that, because of his formidable magic power, this clone was not at a disadvantage when fighting Roy…

F*ck, is a demon king really that strong?

No wonder Beelzebub didn’t destroy this shell. As long as he could find enough materials and a method, this shell really could create a powerful clone.

From the way the clone fought, Roy could roughly guess what kind of demon Beelzebub was. In addition to having a powerful regenerative ability, Beelzebub should be one of the rare demons in the Abyss who used wind magic.

Of course, he should still have dark magic abilities. Needless to say, Roy believed that his clone should have also inherited them. If he continued to attack him, he might use them.

After withstanding the air vortex shot by his clone, Roy was about to fight back, but at this moment, Benia’s anxious voice came from behind. “Darling, stop quickly. Don’t continue probing!”

“Huh? Why?” Roy looked back at her in puzzlement.

At this moment, Benia’s situation was indeed serious. In the wind blade storm just now, she had lost a lot of blood, and blood covered her entire body. Even with her recovery ability, she could not recover from her injuries in a short time. She was half-prone on the ground and said solemnly, “I remember something. Beelzebub has another title in the Abyss… the King of Plagues!” “You mean…” Roy’s eyes widened when he heard this title.

Benia nodded. “Yes. I suspect that the reason why Beelzebub uses wind magic is that he can rely on the wind to spread his plague and virus. If you continue fighting with your clone, he may activate his ability to use the virus. Although this place is tens of kilometers underground, no one can say for sure whether it will spread to our territory. You have to know that Beelzebub’s virus is a powerful disease that even demons aren’t immune to…”

Benia’s words made Roy have to take it seriously. He also had a virus in his body, the mutated T-Virus. But just because he had the virus, it did not mean that other viruses would not infect him.

Ordinary viruses that could infect humans certainly did not work on demons, but how could Beelzebub’s virus be so simple? The probing could only end here. What abilities did the clone have? He could wait until he fused with his clone before slowly exploring, but he could not let him use them here. He put away Frostmourne and raised his palm at the clone. “Okay, stop!” Although the clone had retaliated against Roy’s attacks, in the end, the clone was still a part of him, so after he gave the order, the clone hesitated for a moment before obediently landing on the ground.

Of course, Roy caught the hesitation of the clone and narrowed his eyes.

It seemed to be true. Although his clone only had a soul fragment, he would still slowly obtain independent consciousness. Perhaps he would gradually become a second Roy after some time.

Roy could not allow this to happen. He felt that he had to fuse with his clone as soon as possible, so he ordered his clone to stand in front of him.

Roy looked straight at the clone, and the clone looked at Roy silently. After a while, Roy said, “You should be able to understand what I’m saying now, right? Then you should understand that we are one, and I will always be the main body. This is something you can’t change!”

Roy was right. He, who had the system, was forever the absolute main body. This was a fact that the clone could never change. As a clone with Roy’s soul fragment, he naturally knew this.

Seeing the clone nod, Roy heaved a sigh of relief. For insurance, when I want to create a clone in the future, it’s best to establish a loyalty contract beforehand. While thinking, he said to the clone, “Fuse! Everything is to make us stronger and better survive in this world!” The clone did not resist Roy’s order. He nodded and stood on the other side of Roy, and they both used Fusion together.

Just like the clone of Uriel’s soul, Roy had given the Fusion skill to the clone when he first created him, so the clone naturally knew how to use it. Although the clone’s form was different from Roy’s main body, it did not matter, and they could still fuse. Fortunately, the clone had not existed for long, so his self-awareness was not too strong. He still obeyed the orders of Roy’s main body, so when he used the Fusion skill, he completed it meticulously.

In the back, Benia did not know what Roy was going to do. She only looked at Roy and his clone in confusion as they made the same strange movements together. When their fingertips and tail tips poked together at the same time, a burst of light suddenly illuminated the entire underground space, making Benia unable to look straight at them.

After the light dissipated, Benia found that Roy’s clone had disappeared, leaving only Roy standing there. Moreover, his current appearance was different from before.

On the demon wings behind Roy, the strange patterns on the clone’s cicada wings had appeared. At the elbows of his two arms, two shiny serrated bone blades were embedded at the back of his elbows, looking as though Roy was holding two scimitars upside down.

In addition, Roy’s demon horns had become much thicker and longer than before. These demon horns were gradually becoming like a crown as they surrounded Roy’s head and stood upright. These were the most obvious three changes, and the place that Benia could not see was Roy’s eyes. Under Roy’s switching, his demon eyes would have a complex compound eye structure from time to time. Of course, this structure was very detailed, and it was usually impossible to tell without getting close and looking closely.

What Benia saw now was naturally Roy’s modified appearance. Of course, he could not allow other insect-type demon structures to appear on his body, especially those disgusting bristles. So the moment the fusion succeeded, Roy modified his appearance in the system space. After retaining some functional structures, what was left was his original appearance.

“Ah!!!” Roy suddenly shouted and released all his magic power. In an instant, a magic power pressure that suffocated Benia almost pressed her down again.

The ground was trembling because of Roy’s magic power, and a large amount of rubble fell from the top of the cave. Then the entire underground space began to shake violently, as though an intense earthquake was happening!

This vibration spread to the surface dozens of kilometers away. In Frostfire City, some low-rank demons who were still building buildings screamed when they were hit by the rocks falling from the earthquake and fled in panic. The middle-rank demons and high-rank demons stared at the ground in astonishment. They could feel that something terrifying was underground. Even more scared were the demon worms moving underground. When they felt Roy’s surging and terrifying magic power pressure, they immediately shrank themselves into balls and hid in the tunnels they dug while shivering. On the other side of the inside of the mountain, the waiting Big Black was the same. Its colossal body meekly curled into a ball, dug a hole on the ground, and hid its head.

Benia’s eyes were full of extraordinary splendor as she looked at Roy floating in the air in adoration. She could roughly guess that Roy had fused with his clone, but such an immense increase in magic power after fusing was something Benia did not expect. Moreover, judging from Roy’s current appearance, he seemed to have gained some of the abilities of his clone after the fusion.

As expected, after the magic power stopped bursting, his entire body suddenly split into millions… no, tens of millions!

At the cost of spending three million souls, Roy reduced the size of the original insect clones of the clone again. From a few centimeters to a few millimeters, the number of clones instantly increased by ten times!

If he had invested some more souls, he could have made them smaller, but he felt that this scale should be enough. Tens of millions of tiny Roys was equivalent to changing from a swarm of flies into a swarm of mosquitoes. When they flapped their wings and flew together, the entire underground space resounded with hair-raising sounds. This swarm of clones was like a dark cloud as they constantly changed their surface area in the air, looking very spectacular.

In Roy’s perception, he could feel that these tens of millions of little Roys had the same consciousness connection. This was a very strange feeling, as though the entire group was sharing a consciousness.

At this moment, Roy suddenly understood the feeling of the Queen of Blades, Kerrigan…

“I…

“… am the Swarm!”

From today onward, this ability will be called Heart of the Swarm! Roy thought…
