I Can Make Everything Level UP

Uvish knew that Billy would attack one of his sides again since attacking the back would make him closer to the tail, and attacking the front would make him an easy target for the claws or even a headbutt. Also, just as Uvish had expected, Billy appeared on the opposite side of the wound.

When that happened, he created a massive gravitational field that made everything around them sink deep into the ground. Even Billy fell to his knees instantly while he felt his bones cracking, but he won't need to get closer this time.

Billy had never tried that before, but he quickly created a sphere of water mixed with oxygen and Sulfur. After adding a bit of Time Skip's power, a sphere of acid was formed, and he fired toward the enemy. The attack had been so effective that Billy frowned when he saw a hole of the same size as the sphere on the enemy's body.

"HAAAAAAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHH!" Uvish screamed from the bottom of his soul.

"Too bad, you should have added Acid Resistance to your system," Billy said when the effects of the gravitational field wore off. "You might have outsmarted me, but I outsmarted your outsmarting!"

Billy used Absolute Conversion to create Sulfur and regular magic to control water and wind. Some time would be needed for the material to become sulfuric acid, but he solved that with a bit of Time Skip. While the enemy was in agony, Billy fired many others of those projectiles.

"What is that spell… it negates endurance and even magic resistance?" The chaos spirit asked.

It made sense that an acid attack could do such a thing, and Billy never felt the need to learn something similar since it was a pretty nasty attack. Still, Uvish deserved that. Come to think of it, and the poison dragon could use something similar…

Amidst his agony, Uvish created another explosion of mana that sent Billy to the distance. He immediately tried to heal himself with the power of the spirit of life spirit. Still, even so, the wounds were healing very slowly… To think that such an attack would also delay the healing process, Billy had also forgotten about that.

Regardless, Uvish realized that Billy could be more than a little troublesome to him, even in that form. He tried to recall which opponent caused him so much trouble in the past, but all of them were a lot weaker than Billy, and they just overpowered Uvish. The situation was different, so he couldn't rely on his experience to come up with a solution. He had to improvise as well.

In the end, Uvish took the next step and did something insane… He Shapeshifted again, but this time, he didn't turn into something that existed. He actually transformed into something that he thought at the moment. His size decreased quite a lot until he was three meters tall. Still, he didn't look even a bit like a human. His body was grey, and one could practically see the muscles of some parts of his body. It didn't look like they were covered by skin, but they also didn't look unprotected.

Uvish, for some reason, imagined a creature that had a pair of horns that pointed to his front. His body was also being covered in a weird husk-like armor that looked pretty sturdy. His eyes had turned red like blood, and one couldn't even see anything aside from the red… The point of his hands and feet were some sharp-looking claws that looked pretty fearsome… the world demon lord was pretty fitting for his new appearance.

"What the hell…" Billy thought when he landed. "Did he face such a creature before?"

"Most likely… He created that form out of his mind," the time spirit replied. "He didn't face anything like that. Even the flying spearmen and their leaders didn't look that ominous."

"I agree… Still, to think that Shapeshifting could be used like that…" Billy said.

"It can't be used like that… He improved my ability just now," the chaos spirit said.

"Are you for real…" Billy said while frowning.

Billy came ready to fight, but he didn't imagine that the enemy would be improving during the fight as well. That was rather troublesome… He still was stronger than Billy, but if he started to become smart now.

Uvish even made some demon-like wings emerge from his back as if he wasn't satisfied with his form. Instead of Shapeshifting, it was more accurate to say that he was mutating… Either way, that couldn't possibly be good since he was transforming into something that could endure Billy's techniques and tricks.

"Are you ready to accept our help now?" The spirit of order said.

"No way, I already said that I would defeat that bastard by myself. Otherwise, I won't feel satisfied when this ends," Billy said. "Besides, this is getting interesting… I wonder if I can copy him…"

Uvish took his time to get used to that new form. Meanwhile, Billy decided to watch and recover as much energy as possible since that world was filled with mana and life. Besides, it was hard to tell how strong the enemy got with that Transformation or what points he had improved.

After doing some tests, Uvish punched the air in front of him, and the attack created a shockwave that created a fissure on the ground that was five kilometers long. With that shape, he could control his strength a lot better than before…

"This is good… I must thank you," Uvish said. "Not only did you grant me some powerful techniques, but you also helped me evolve myself."

"I didn't grant anything, you stole my body and knowledge, and I didn't help you. I forced you to use your head a little," Billy said. "I hope that you aren't damaging my body while transforming like that. Otherwise, you will pay for your tab with a lot more interest. My wives will get mad and compared to them, your rage is like the fury of newborn cat."
