From a distance, Yoru saw several silhouettes plunging from the magic circle and landing amidst the zombie horde.

"Ah... it was 13 that came out earlier, right?" Yoru was a little unsure.

[Yeah, 13. How about you joint the attack now]

"Wait a minute. They're not moving. We'll jump in if they do." Yoru looked a little worried.

[Individual Yoru Kagami Level up]

"Opss,,, level up again. Let's just wait until I'm lvl 10 maybe."

[Okay then. And judging from the status of the pawn that came out earlier. Looks like nothing has changed]

"That's good then. They didn't get any stronger. That way, dealing with them would be easier."

Yoru didn't do anything because Pawn didn't do anything either and just stood looking at Yoru. Yoru looked a little relieved by what happened now. But he was also still a bit worried about the Three creatures hovering under the magic circle.

"If it's like this, pawns won't be a problem. However, those three will still be a problem."

[Perhaps our troubles will be more than they should be. You see the lvl that Bishop has. He was already lvl 50. Meaning he was on the verge of evolution. If the Bishop was already at that level. How about Queen and King. You can imagine that isn't it]

"Yeah. And here maybe I'll only be level 50 too, so I'll only be on par with Bishop." Yoru looked worried and nervous.

Yoru thought with all the zombies attacking now. The chances of him leveling up were only to lvl 50. So, he still wouldn't be able to become an opponent for the Queen or the King.

[Maybe we need to evolve yourself faster than we should]

"Evolution? Can I really able to do that?" Yoru calmed down a bit as he had a solution.

[Yes. And with my help. You can evolve today. If we can exterminate all the zombies attacking now]

[Individual Yoru Kagami Level up]

"What must be done if I want to evolve?"

[First. You must reach the highest lvl human could be. That is 50. Second, you have to modify your whole body. Only those two conditions]

"Then we can... Wait a minute. Modify the whole body? Didn't we not yet touch the heart and brain?"

You might be reading a stolen copy. Visit Royal Road for the authentic version.

[I can help you to finish the modification process faster. If you are already lvl 50. The amount of mana you have will be more then right now. So I can use more mana for the modification process. And with Undying Body. I don't have to worry about your body being destroyed. It is just. This process will be very painful. Because basically. I will destroy your heart and brain again and again]

Yoru immediately got goosebumps hearing the explanation from System.

"Is there another way?"

[No. That's the only way we have if you want to evolve quickly]

Yoru looked deep in thought. He considered all the possibilities that could happen.

Elsewhere, before a magic circle appears above the zombie horde. Saeko seemed to be enjoying what was going on.

"Saeko, don't go too far!" Shirley shouted a reminder.

Saeko then stopped and looked around her, she saw Shirley was slightly away from her position.

"Sorry." Saeko answered while running towards Shirley.

"Huhf, I know you can't wait to complete your mission and these zombies are all weak. But don't let your guard down. The more zombies we kill, the less room we can move because of the many corpses scattered around. So it will be more dangerous too. Not to mention later if pawn suddenly…” Shirley stop talking because she felt something was off.

"Shirley? What's wrong" Saeko was confused why Shirley suddenly stopped talking.

"Nothing, I just feel that something is wrong." Shirley then looked at Yoru who was floating and saw Yoru focused on the sky above the zombie horde.

'What is in that place?" Shirley curious why Yoru looking at that place.

Seeing that, Shirley also focused in the same place.

"Saeko, can you cover me for a bit?" Said Shirley with a serious face.

"Hmm... Okay..." Saeko then went into a bit of a rage again. But this time she didn't advance too far.

Shirley suddenly shook uncontrollably. She herself was confused by what had happened. Until finally she saw a fairly large magic circle appear in the sky above the zombie hordes. And she became very anxious and frightened when something came out of the magic circle.

"What kind of monster is that?!" Shirley shouted.

Saeko immediately turned towards Shirley after hearing Shirley scream. And when she saw Shirley looking somewhere, Saeko also looked in the same direction and was surprised by what she saw.

"That thing is as strong or maybe stronger than Yoru." Saeko said.

Shirley immediately turned towards Saeko after hearing what Saeko said. "You can feel it?"

"Maybe not as sensitive as you are. But as someone trying to be a master. I know that he is not an ordinary creature. Especially with the shield on his back, I'm sure he's pretty strong. I might die with just one hit." Saeko looked disappointed with herself.

"Yeah, Yoru might not be able to fight that creature." Shirley looked really worried.

However, the worries of the two of them were heightened when another being stepped out of the magic circle.

Both of them suddenly stopped moving because of the unbearable fear. Because their bodies stopped moving. Zombies can immediately approach the two of them and attack without any resistance at all.

However, when the two of them were almost injured by a zombie attack. Three katanas suddenly appeared and killed all the zombies near them.

Both of them were surprised by the katana that suddenly appeared and floated near them. Both of them realized what was happening and looked at Yoru. However, Yoru was still focused on the two beings under the magic circle.

The two then looked at each other and nodded their heads.

"Looks like we don't need to think about this." Saeko said.

"Yes, we better focus on all the zombies here." Shirley looked a little calm.

"Maybe if I can complete my mission. I'll be able to fight them a bit." Saeko sounded excited, but she herself still wasn't sure if she could fight them.

"I think it's still a bit impossible." Shirley tried to be a little realistic.

"You think so too?" Although slightly disappointed, Saeko seemed to smile slightly.

Both smiled after realizing what the money had to do with them.

But that smile disappeared when something so sinister emerged from the magic circle.

"That one, we don't need to think about it anymore." Shirley smiled forcedly.

"Yes, that's certain. It's highly improbable." Saeko also smiled even though she had to.

"We really can't help it." Saeko looked disappointed.

"If we survive after this. We need to force Yoru a bit to train us to make us stronger." Shirley seems to have a new determination.

Saeko nodded her head. "And now. We have to finish off all the zombies here faster." Saeko smiled sadistically.

"This time I won't say much. Let's just clean all this as fast as possible." Shirley looked very serious.

After that. The two of them rampaged and finished off the zombies at a speed that was incomparable to before.

[Looks like Saeko and Shirley are having a bit of fun there]

"Yeah, actually, what happened to the two of them?"

[Maybe because the appearance of Bishop, Knight, and Rook made them excited and want to get stronger]

"They don't have to do all that." Yoru looked a little confused.

[Because they probably hope to help you]

"Sigh... But if they try too hard, I'm just afraid that they will ruin themselves." Yoru said a little worried seeing Saeko who was slashing zombies non-stop and Shirley who was using her magic to blow up all the zombies around her."
