Theo had regrouped with Ava and took off from the ground, flying back to the top of the hill to get enough distance to observe the enemies.

"…

" Theo pinched the bridge of his nose while seeing how all the zombies came out.

"Doesn't this mean there are numerous undead in this valley?

"

"Kyu?!

" Ava tilted her head in confusion.

"I mean, the fact that ten more are coming out means there are still more zombies hiding underground.

"

"Kyu!

" Ava suddenly came to a realization and looked at the valley from the bottom of the hill to the horizon. They were supposed to go in that direction, but it also meant they needed to cross numerous zombies hiding underground.

"Right… There may be thousands of zombies inside. If all of them come out at once, it's gonna be troublesome.

" Theo sighed.

Luckily, the zombie seemed to have short sight since they couldn't find him on this hill despite him openly showing his appearance. Like the Zombie Warrior, they should have a certain level of perception that could sense and see their surroundings.

"Kyu?!

" Ava looked at Theo with a curious gaze.

"Kill them huh… It's easier said than done.

" Theo thought for a moment.

"To be honest, I am not sure whether I can handle ten monsters at once. No, even eight monsters will seriously put me into trouble. You can take two and kill them, but you need time from me.

"

Ava looked down, feeling that the situation was trickier than she expected.

"I have spent a week to come here. And I'm planning to spend one week each in Mystic Valley, Big Sin Valley, and Lambert Lake before returning home. In that case, how about this? I will kill those zombies here for a week. If we can't annihilate them, I will use my Telekinesis to go from one hill to another, looping around this place until we reach the Big Sin Valley.

"I am not sure myself, but I don't think the zombies can go out of this place or the humans would have experienced the zombie disaster.

"That's why we will kill at least three hundred monsters in the span of three weeks.

" Theo looked down.

"For now, we need more information regarding the monsters.

"

"Kyu, Kyu!

" Ava jumped to the ground before tapping it a few times.

"I don't understand.

" Theo shook his head in confusion.

Ava suddenly scooped the dirt and threw it.

"So you want me to use the dirt? No, you want me to use my Telekinesis to throw a giant chunk of dirt at them?

"

Ava nodded a few times, confirming Theo's guess.

"It's not possible. First of all, I don't think it's going to be that good as an attack. As for the distraction, it won't give us too much time. Hence, we need a different plan.

"Also, due to the limitation of our stamina and Magic Power, I think fifty to a hundred zombies a day are good enough. It should allow me to level up three times a day. It's going to be a bit slower in a few days because my level will be approaching their levels, but I don't think that's a disadvantage.

"My power will certainly reach a level where I don't need to be afraid of these zombies anymore.

" Theo thought for a moment and stared at the entire valley.

"I have an idea.

"

"Kyu!

" Ava blinked her eyes with excitement.

"I need your cooperation. Instead of you fighting two of them while I'm fending off eight of them, we are going to fight together. In other words, you are going to kill more than two while I'm supporting you.

" Theo smiled.

"Kyu?!

"

"Yeah. You are going to be in the front. I will support you from behind before killing them when the time is right. Of course, I'm going to kill more… Do you think you can defeat me?

" Theo smirked.

"Kyu, Kyu!

" Ava pouted and looked away as if she didn't agree with that statement.

"Alright. The battle is on.

" Theo smiled.

"For now, I want you to wait for my signal before moving forward. I am assuming that the zombies have a certain range of perceptions, making them aware of our presence.

"In other words, as long as we don't reach their range, we won't call more zombies. With this strategy, we can handle three to five of them at a time, allowing us to kill a total of fifty to one hundred zombies per day while conserving enough Magic Power.

"

Ava nodded, agreeing with Theo. She hopped back on his shoulder as if she would wait there until Theo gave a signal.

Seeing her cooperation, Theo's expression became serious as he took another look at the zombies' movements.

"Let's go.

" Theo used his Telekinesis again to bring them down the hill.

As soon as they stepped on the ground—a hundred feet away—three zombies suddenly turned around. The others only did the same after the three zombies made such a reaction.

"…

" Theo narrowed his eyes, taking note of their reaction while leaping back to avoid waking up other zombies.

There were three Zombie Warriors, one Zombie Mage, two Zombie Archers, and four Zombie Knights, so he knew this would be a tough battle.

"Our targets are the Mage and Archers… The ones with the staff and bows on their hands.

" Theo said and summoned his clone.

"Kyu!

" Ava nodded a few times.

"I will be taking you to them, so be prepared.

" Theo smiled as he released his Magic Bullets, summoning a total of forty Magic Bullets.

He and his clone pointed those bullets to the front as the four Zombie Knights stepped forward with their shields.

Theo released the Magic Bullets straight as if he had no intention of defeating the zombies since all they needed to do was put their shields in front.

That was what the zombies did while running forward with the Zombie Warriors following right behind them.

Theo waited for a bit more until they were only six feet away from him. When all of them tried to plunge their weapons at him, Theo finally used his Blink, carrying Ava to the Zombie Archers and Mage.

"Now.

"

They arrived right next to them, preparing to launch their attack.

"It's killing time.

"
