Five minutes later, the group went toward the underground nest containing around five hundred magical beasts.

Kai needed to be careful in this area, not wanting to be ambushed by a Protector again, so he relied on Sofia in this matter.

She checked a few times, ensuring there was no ambush or whatsoever with her special instinct, so Kai finally decided to search the entrance of this nest.

It turned out searching for an entrance was harder than she thought because the entrance was a bit hidden.

"Over here." Tasha clapped her hand once and raised her hand, calling the others. They were walking around in the alpine, so it was a bit hard to move around.

It took them around one minute before they could gather in front of a hidden entrance behind a giant rock. It was a rock that blocked their way, but they would find it if one traveled above it. However, none of his group actually flew to the sky in case they found a flying magical beast. If that happened, it would be troublesome.

"By the way, Sofia, do you find anything in our surroundings? Because this battle will be quite big and loud, I am afraid they will attract magical beasts from the surroundings. And as you already know, I can't create a Sound Insulation this big." Kai asked while adding inwardly, 'Without all my magic power of course.'

"Nothing big. There are three groups around us, but all of them are only a small ten to twenty groups. I believe we can take care of them in an instant, especially considering none of them was as strong as the bear earlier." Sofia shook her head.

"Understood. We can proceed then." Kai nodded and entered the underground nest. Darkness immediately surrounded them as it was a bit too hard to see inside this place.

Kai relied on his hearing to react while Sofia used her eyes to see the incoming dangers. Tasha and Ayaka put on their night vision goggles as Michelle didn't really need one. In fact, she was the only one getting stronger in this environment.

They were met with holes from left and right as the group looked at Kai.

Kai thought for a moment and activated his Sound Insulation. The group looked not at him but at their surroundings to ensure there was no blind spot.

He then started explaining their current situation. "We have arrived at the first junction. We can go to the front where we are greeted by fifty magical beasts immediately or go to the left and right, which have ten to twenty monsters respectively."

"We will stick around with you because it will be safer to sweep an underground nest as a team," Michelle suggested without hesitation.

"I agree with her. Besides, my bow doesn't really work here unless we find a big room for me to use this one." Tasha nodded before shrugging as if it didn't really matter. "I can do other things though."

Ayaka and Sofia also didn't have any problem and agreed by nodding their heads.

"In that case, I will go according to my own way as we will sweep every single magical beast from the perimeter before moving to the center of this nest. If possible, I want to make this as a test to see your reaction speed and technique…"

"Are you going to do the thing as you did back then?" Tasha asked.

"Yes. You might not have known it, but I have done similar things with Teacher, so I believe this is a good chance to test your ability." Kai smiled, looking at the four ladies. Kai wouldn't suggest this if Evan were around because Evan wouldn't be able to keep up their movement. But these ladies were different.

They were strong fighters that should have the ability to keep up his movement. The problem would be whether they could or not.

"Sure." Michelle smiled as a dark aura started coming out of her body. This was the technique that enhanced her basic body ability to the utmost limit by using the darkness, so she was pretty sure she could keep up with Kai.

"Interesting." Ayaka was pretty eager to do this as well, considering she had the blood of wildebeest that boosted her speed.

Sofia thought for a moment because she didn't really have anything to strengthen her. Nonetheless, her ability was top notch, so she didn't really mind. "I will do my best. But I am thinking of changing my position."

"Position?"

"I have been supporting you in the back, but now I want to move to the middle because too far from the target will make me lose accuracy in this environment." Sofia nodded.

"Alright. You can do whatever you want." Kai nodded.

"Thank you."

"I will also do the same then." Tasha raised her hand and decided to retract her bow as her hands suddenly glowed. Lightning started flashing around her hands before covering them with this flashy purple light.

"This is…" Kai and the others were confused because this was the first time they saw this.

"You could say that these two gauntlets made of my lightning could function as a pistol. I can shoot up a small Lightning Piercer with this. Although the strength is not comparable to the one with the bow, I will be very versatile by using this to fight in a close environment like this." Tasha explained.

"Sure. If you are confident in fighting with it, I won't say anything. Just make sure you don't endanger yourself." Kai nodded with a serious expression.

"Leave it to me." Tasha gave a thumb up.

"One last thing, because this is not a raid like the previous raid mission, if we make too much noise, the magical beasts might also run to the outside instead of searching for us. When that time comes, I bet they are going to call a reinforcement, so make sure your step doesn't really make a loud sound and don't talk with each other, let alone shouting, so there wouldn't be any sound echoing in the tunnel." Kai sent the last warning in which the rest nodded with a serious expression.

Satisfied with their reaction, Kai decided to go to the left because he wanted an easy sweep.

"Let's go. In this tunnel, we will meet four magical beasts before finding eleven more in a bigger area." Kai pointed to the tunnel and walked inside it.

When everyone entered, he picked up his pace, and the others started running to follow him.

The first monster was a red ant, which they killed in a split second. It continued this way for another three beasts before they reached the bigger room at the end of the tunnel.

Sofia and Ayaka were a bit nervous because they couldn't use their magic because it would create a loud sound. Hence, Ayaka decided to fight with her spear alone during this time while Sofia created a smaller portion of ice like a bullet and shot them toward the magical beasts.

Kai still maintained his speed as he glanced to the back and nodded, signaling them to get ready.

The group's expression turned serious as they stepped inside the room and found eight ants and three hares.

Without a word, Kai leaped toward the magical beasts, wanting to see their reaction speed. Because they needed to match his movement, they would need to understand which magical beasts he killed and which ones they needed to kill. This took a lot of concentration as the girls seemed to react a bit late.

Michelle and Ayaka were in the front and immediately went left and right. If Kai destroyed the middle, they needed to sweep the entire magical beast group from the edge and push them to the Kai, so he could kill more.

Meanwhile, Tasha waved her hands as two lightning arrows flew out of the gloves, piercing through their heads.

Kai saw Tasha taking the first kill and decided to step forward, splitting two ants in front of him into two. At the same time, he used his Sound Blast to push them to the side, creating a weird wave that made the magical beasts stumbled.

He didn't care after that as he made his way before the hares.

Suddenly, the temperature dropped because they suddenly experienced rain inside an underground nest. And it was not normal rain. Instead, it was a freaking ice rain.

The ice cubes looked packed with power as some of them managed to pierce the hares' body. Kai decided to retract one of his swords before using that free hand to create a small shield to block the rain while killing the hare that was under this heavy rain.

Using his Sound Blast again, he jumped from hare to hare, cutting them with his Vibration Sword. And just like that, the three hares just died.

And without anyone realizing it, Michelle and Ayaka seemed to have finished as well, making him impress.

"Great job." Kai nodded while summoning his sword again. "Now we will immediately head to the next place as soon as we clear an area. Make sure you don't have a slight delay… You can even treat it as you are in the middle of magical beast rank where you need to breakthrough by using speed. The moment you stop, the magical beasts will surround you and kill you."

"You are saying a pretty scary thing sometimes." Michelle shrugged before grinning. "I am up for it though."

"If that is the case, we can clear the nest within thirty minutes. That is an achievement by itself, so I will claim the MVP (Most Valuable Person) in this objective." Ayaka nodded.

"No, no. It's me." Sofia raised her hand as if she took pride because she helped Kai defeat three hares instantly.

Tasha only shrugged and glanced at Kai, telling him to start.

Kai nodded and ran again. "Let's go."
