Souta used his Burrow skill to go deep under the mountain. He created a place where he could evolve peacefully.

After creating a wide space under the mountain, he then summoned Yuko who was currently fighting the top fighters of the Great Astley Empire alone.

Ohm!

Yuko appeared beside him and she immediately looked around. Souta notified her before he summoned her in this place. He took out the transmission talisman and called Lydia.

"Souta! is that you?!

" Lydia's voice sounded in the talisman in his hand.

"Yeah, I'm going to tell you something important that will help us. You will free the prisoners of this world. You'll free them from their jails and that will create chaos in this world. It will also help us diverting the attention of the people that were chasing us.

"

He said to her in a low voice.

"Is that so... Then, where are you?!

" Lydia asked.

"I'm currently hiding in the mountain. You don't have to wait for me. Also, don't forget to do what I tell you.

" Souta said to her seriously. This quest was important for him as it was part of the chain quest.

"Okay, I'll do it. But I'm going to rest for an hour or two before I do it.

" Lydia said to him.

The prisoners of this world were inside the territory of the wardens. They were bind and control there. Also, the security of each place was tight so she couldn't sneak inside while she was tired.

Tens of thousands of creatures were being detained in each prison. Each warden had twelve prisons under their territory. It was divided into three ranks. The disaster, calamity, and catastrophe rank.

The people that were detained in disaster prison weren't that strong. Mostly they were just ordinary people. While the strongest vile creatures were being detained in the catastrophe prison.

So for them to create chaos in this world, they had to release the creatures in the catastrophe rank prison.

"That's fine. It's better to do it when you're in your peak.

" Souta nodded his head.

All the core members of the Dark Oculus Legion had transmission talismans. He provided it to them so that they could report quickly if something happened.

"Where are you, Souta? There's news that you died in the battle in the Blackrock City... Tell me what really happened.

"

Alice's voice sounded in the talisman.

"It's a long story but I'm going to tell you that I'm in a world called Prison World, another sub-world. It's under the rule of the people that are attacking that world, the Great Astley Empire.

" Souta paused for a moment before he continued,

"You can go all out and enter the battle. The army of the Great Astley Empire had a machine that could transport you into other worlds so you know what to do?

"

"Yeah, I know so where do we meet?

" Alice nodded and asked. She understood what he wanted her to do.

"To the homeworld of the Great Astley Empire... I'll see you there,

" Souta said to her, and then he ended the call.

...

The warden, two generals, and the commanders were shocked when they found that Yuko suddenly disappeared in front of them.

They were battling that strange bear who had the power of dragon's energy but somehow she just disappeared like a bubble.

"What the?!

"

"The monster disappeared!!

"

There's not even a trace of the bear on the battlefield aside from the lingering dragon's energy in the atmosphere.

"Tsk! We let the traitor escape and we couldn't even kill that bear! Damn!

"

General Asimon gritted his teeth in anger. They couldn't even capture one of them yet the casualties that they've suffered were high.

"They are in this world so we will find them soon.

" General Albert said as he looked at his subordinates and ordered,

"Find those people. Use everything to find them as soon as possible. We can't let the others know that we failed to capture them.

"

Warden Mackenzie looked at them and said,

"I'll lock down the entire down. I'll tell the other wardens about it so they could help us in locating those people.

"

After that, the whole army of the Great Astley Empire spread out to find Souta's group. All possible locations were being observed and examined thoroughly.

Dozens of sh.i.p.s flew in the sky and wandered in every direction hoping to find their targets. Despite mobilizing more than five hundred thousand soldiers, they still couldn't find their target. Well, the Prison World was a large world that has three gigantic continents.

Five hundred thousand people weren't enough. That's why they had to ask the other wardens that ruled this world.

Souta turned to Yuko and said,

"Yuko, go outside and protect this place no matter what happens. Don't let anybody approach this place.

"

Yuko understood him so she went above to guard this place.

After she left the place, Souta closed the whole space and created a barrier to make sure of it.

'What are you going to do?' Saya asked him.

'I'm preparing myself. I felt that I reached the limit of second evolution so I will try it today.' Souta replied to her.

'What?!' Saya was surprised when she heard his words. 'You're going to evolve...?'

'Yes, it's not that surprising since Yuko already evolved and become a Scorching Red Bear.' Souta said while shrugging his shoulder.

'But... Yuko is already a second evolution but you... you just become a second evolution monster. A year hasn't even passed since your last evolution.' Saya was feeling shocked.

She wasn't a monster so she didn't know how it feels when a monster felt that they could evolve. But if Souta said so then it must be right.

A third evolution monster also called as true monster. She didn't know how strong Souta would get after the evolution. He was currently a peak B-rank so maybe an S-rank.

'Please be quiet and I will start now. Let's continue our talk after this.' Souta said to her as he sat down and closed his eyes. The system interface flashed before him.

Race: Mutated Goblin Corruptor

Level: 40

He was currently level 40 and reached the level required for his next evolution. He then looked at the system prompt that he received.

You've reached the level requirement for the next evolution!

If you want to continue leveling up please proceed to evolution!

Do you want to evolve? Yes

/No?

Yes. Souta didn't hesitate to answer.

Race Detected: Mutated Goblin Corruptor!

The system detected six evolution paths available!

Please choose one of the six following evolutions. Warning! The evolution is irreversible. Please choose wisely.

Hobgoblin General

Goblin Shadow Shaman

Mutated Dark Goblin

Mutated Goblin Reaper

Shadow Sweeper

Blood Goblin

There were six available options for him. The first option Hobgoblin General was more on a fighter and brawl type. It boasted great strength among the other goblins. The Goblin Shadow Shaman and Mutated Dark Goblin were suitable for pure mage type. While the Mutated Goblin Reaper and Shadow Sweeper were much more inclined on speed. Lastly, the Blood Goblin has versatile abilities.

Well, Souta guessed that he opened the two mutated evolution paths when he mutated. The other two shadow types must be because of his darkness abilities rising to another level when he acquired Shadow Body when he became a Battle Mage.

The Blood Goblin. He unlocked it by consuming the ingredients that he received from Raeshka. While the other one was the normal evolution path for him.

Blood Goblin was his target and he wouldn't change his mind. He needed to consume the blood of thirty different third evolution monsters just to get it so it was pretty strong. If he was alone he would be having a hard time getting those blood that he consumed.

Selection complete.

Undergoing race evolution.

Boom!

A powerful surge of energy exploded within Souta's body. Electric like energy violently strikes everything around him. After a few moments, the sparks stopped as it became a white light that enveloped his body like a coccoon.

Souta was looking at his system and he didn't even realize that he was already inside his inner consciousness.

'What?!'

He looked around and found all the spells imprinted in this place. He then saw a glow of light thumping a huge amount of energy. Veins spread out and it poured knowledge into his mind.

Monster Orb has been created!

Converting all the mana inside the body into best feram!

Converting completed!

The attribute Mana has been changed to Best Feram!

You've learned Monster Language!

All skills have been upgraded!

Drawing ten abilities from the blood!

Drawing completed!

Please choose five abilities from the ten options below!

This is it. This is what he wanted from this evolution path. The abilities of another monster were in his sight. This was the reason why he wanted to become a Blood Goblin which was pretty average in terms of stats. Well, he didn't need to worry about stats as his Soul Blood Earring will increase it. Also, there were millions of souls out there that could increase his stats by 200 each.
