Even though this was an important battle, Theo still experimented with his new ability. It couldn't be helped since this Inverted World was the only ability that was effective against the slime.

Theo had another plan that could allow him to inflict some damage on the slime. Clone Theo stomped the ground with all his might, releasing a surge of wind pressure to the top of the slime.

'Ascension Step, Tenth Step!' Theo even used the Mirage World to imbue the Wind Power, making it look like the Wind Emperor himself was the one that used this technique.

The torrential wind was so violent that it looked like it could penetrate the ground easily. But for the slime, this was something easy to handle since he had both Dissolve and Devouring Power.

The wind was disrupted, losing some of its energy. However, Theo persisted in it and pushed through.

At the last moment, Theo changed the wind's attribute with the Inverted World from a raging wind to one filled with Disintegration power.

This was the same disintegrating wind the Wind Emperor once had. It could disintegrate everything, including the Devouring and Dissolve Power. So, it should be effective against the slime's body as well.

But before the wind could touch the slime, a translucent barrier appeared. The barrier formed in all directions, isolating the wind from the outside world.

When it touched the barrier, it began disintegrating everything around it, albeit only limited to the barrier.

"Do you think it will work the way you intended to? You are thinking too highly of yourself, Theodore Griffith." The slime seemed to be annoyed and angry. Theo had done a lot of things to him, including being the biggest contributor to removing his body.

Theo couldn't help but smile when he heard that remark. "Of course, I'm not underestimating you. I know that you can stop my attack just fine. But"

The slime suddenly felt a huge fluctuation of Magic Power. He suddenly shifted his focus from Theo to the Goddess of Death.

That was right. The Goddess of Death was preparing something this whole time. He forgot about her for a second.

However, if he took a closer look at the situation, he would realize that Theo had made him forget about her. First, he distracted his attention before using the illusion so that the energy around her and other things couldn't be sensed by the slime.

When he saw the Goddess of Death, he couldn't help but feel something beyond this world.

Hel's blood-red eyes flashed and emitted killing intent that was so strong that it released a small shock wave that sucked all the lives of everything around her. The trees withered in an instant, the boulder turned into sand, and the soil became dry.

The world around her felt like they were not allowed to live anymore.

When she clapped her hands, a huge red gate appeared on her back. The gate reached as high as two hundred feet. Just from left to right, it stretched for at least fifty feet.

Even Theo, in his dragon form, couldn't help but feel chills down his spine, making him return to the human form if he didn't want to get caught in the attack.

"Afterlife Border," Hel muttered the name as the Death Avatar behind her moved toward the gate.

This tiny skeleton was placing both hands on the gate before it began releasing the black Magic Power that gave him enough strength to push the gate.

"!!!" Theo's body trembled instinctively as he couldn't help but mutter, "Is this seriously an A Rank Skill? No, I'm afraid that the gate itself is an A Rank Skill, but that skill is connected to something even more ridiculous. As expected of Hel, I can still learn a lot from her even after all this."

When the gate was opened, there was a red eye from behind the gate. Because it was only opened slightly, they could only catch a glimpse of it.

But when they saw this eye, Theo's soul was trembling as though the eye was sucking the life out of him. Even the slime seemed to be corrupted from the eye as multiple black spots began to form on the slime's body.

There was a huge black cross appearing out of nowhere.

The slime noticed the positioning and realized it was a cross that marked him. It was no wonder that he was the one most affected by this power.

He hurriedly used his power to disintegrate the cross while forming multiple tentacles around the gate. Some of them captured the Death Avatar, while some hurriedly closed the gate.

*Clang!*

Theo gritted his teeth, never thinking his reaction speed would decrease tremendously from that eye alone.

At the same time, the Goddess of Death seemed to be unable to do anything when the gate was still there. It was an overwhelming technique, but the risk was also huge. And because she used all the Magic Power she harvested from all the dead on this land, it was clear that this was something she could only use once.

However, the power could easily be seen.

The slime had to excrete all the rotten parts from his body. Just from that attack alone, he had to expel at least ten percent of his body.

With this, they managed to weaken the slime even further. The slime was also still shocked by the power Hel was hiding.

'As expected of the Goddess of Death, one of the strongest Goddesses in the mythology. And according to some sources, she didn't leave Helheim during Ragnarok because she had to take care of all the souls because of Ragnarok. I wonder what would happen if she took part in that fight?'

Theo gulped down. However, the excitement was cut short when Hel suddenly spat a mouthful of blood.

"Gah." Hel's face became pale. Theo hurriedly visited her to check her condition. "Are you OK?"

"Yeah. I used a bit too much power That technique was a double-edged sword, you see" Hel sighed.

"Though, what is that eye? I feel like it's alive" Theo sucked a cold breath.

"Alive? You couldn't be more wrong. That is death itself." Hel smiled with a pale face.
