The Evolution of a Goblin to the Peak

"You! Are you serious?!" Souta was shocked. He didn't even know that Saya could teach him skills. If he knew this from the beginning then he would ask her.

'Yes, I'm serious. I want to teach you some skills that will help you in your adventure. I'm sure that you will become a great person in the future just like my past wielder, no, even without me you will still become an influential figure. You're a future powerhouse.' Saya said in a serious tone.

'So the past wielders of vajra sword are all big shots. It seems that I have to look into it later so I could gain more information about Saya.' Souta thought as he rubbed his chin.

'Well, I'm sure that you won't let go of me.' Saya suddenly said in a tired tone.

"Of course, you're the best weapon I currently have so even if you don't want it I will use you to slay my enemies," Souta said as a matter of fact.

'You're the first monster who wielded me and the first person I saw that will not succumb to my power. All of my past wielders are great people but they couldn't handle the effects of using my powers. They lost themselves and become mindless people that will slaughter everyone in their sight.'

"Hmm...? So the people that you possessed in the ruin when I first saw you are..."

'Yeah, they couldn't handle my powers. They lost their ability to think after taking in the energy of vajra. The same thing happened to my past wielders.' Saya answered him.

"I see... So why are you in that ruins?" Souta asked a simple question.

'Me? Oh, the people from the Zomus country sealed me in that place but the seal weakened with the passage of time. That ruins was a research lab seven hundred years ago but they abandoned it because the energy of the vajra is corrupting their mind.'

"I get it. So that's the reason why you are in that place. Still, three hundred years ago, huh? My parents aren't even born at that time." Souta understood everything why she was there in the ruin.

Saya's energy was pure of malice and hatred. This was the reason why most of the people that held her lost their mind. Overused of her energy could decrease a person's lifeforce.

"So that's the reason why you told me that you will take ten years of my lifespans when you let me borrowed your power. You calculated my power and the energy that I will borrow, and you came to a decision that I will lose ten years of my lifespan. You said that it was a contract and you will take my lifespan in return for borrowing your energy."

'Yes, I didn't even take your lifespan. The energy that you borrow caused you to lose your lifespan. It wasn't because I took it.'

Souta contemplated for a while before he opened his mouth, "Hmm... Your energy is like poison. Just like an undead's energy. Don't tell me you're undead."

'I don't think it's the right word to use but I also can't deny that I have properties of an undead. Hays... It's a long story...'

"Tell me. I have a lot of time." Souta said.

'I will make it short as I don't want to talk about but since I've decided to support you I will tell you some of my past.' Saya said in a tired tone.

'A long long time ago, I'm the sole survivor of the noble vajra clan. Everyone died except for me so I'm the only person left in my race. I thought that I would be able to revive our clan but the other races treated me badly. Yeah, they killed me. I don't even know why or how but I was filled with anger and hatred at that time.

'The next thing I found was that my consciousness was inside the sword. I saw a man wearing a black robe in front of me. That man was looking at me with disappointment in his eyes. He then left without saying another word.

'Later on, people called me [Vajra Sword Saya]. I became a dark-grade weapon. My corrupted energy turned everyone into a mindless killer. That time, I found that the first man that I saw ever since I woke up was a famous blacksmith and he was also an evil necromancer that brought terror to the continent.'

Souta could feel her emotion in her words. He never heard her like this. Her tone was different from normal.

"Thanks for telling me your past." In the end, Souta could only thank her for trusting him to the point that she told him her past.

'Ufufu, do you pity me now that you've heard my past? What if I'm bluffing and just trying to get your pity? What would you do?' Saya laughed as she asked Souta in a seductive tone.

"I believe in what you said," Souta said strongly. According to the information that he gathered from Cluster before, Ieshi clan vanished and the vajra race was annihilated along with the other dominant race at that time.

'...Anyway, let's stop talking about my past. I will start teaching you right now.'

"...Fine, tell me everything that I need to do." Souta smiled as he gripped the sword in his hand. He wondered how Saya would teach him sword skill.

'Sit down comfortably and close your eyes.' Saya said in a strict tone.

Souta followed her words as he sat down in a lotus position before closing his eyes. This was the best position for him when meditating.

Ohm!

Suddenly, he felt that he was sucked by something unknown. His whole body felt weightless and he couldn't sense everything that was happening around him. He felt that he was in a completely different place.

Nevertheless, Souta didn't open his eyes without Saya's permission. She was going to become his teacher from now on so he had to follow her instruction.

After a while, he heard Saya's words saying that he could open his eyes.

Souta slowly opened his eyes and found that he was in a place. He was standing in the middle of an endless black space with small stars around it.

"What is this place?" He muttered as he looked down. He saw endless black space below him but for some reason, he didn't fall towards it. Raising his feet, he tapped the ground using his shoes. He felt that there was an invisible floor that made it possible for him to stand in this place.

"This is my inner consciousness." Saya's voice sounded.

"Hmm...?" Souta looked up and saw the same red figure that he fought in that underground place. This figure was none other than Saya herself.

"This is my inner consciousness," Saya said once again.

"Why are we here?" Souta asked while looking around.

"Of course, I'm going to train you. I can't materialize in the real world so I had to pull you into my inner consciousness. Before you ask a question why are we here let me tell you something..." Saya said as she stopped Souta from asking questions.

Souta was feeling weird looking at the red figure with no face except for the mouth. 'Is this really the appearance of vajra race? No, no, that's not happening. She just looked like that because of negative energy.' He heavily shook his head.

"People who reach a certain level of strength wouldn't train their skills in an open ground. It was because they have a power to alter the map. Destroying mountains, creating oceans or islands are all possible with people who reach higher levels. Imagine a powerful water user training beside the empire." Saya said to him.

"Yeah, a flood will swallow the empire if something wrong happened." Souta nodded at her as he understood her point. Yeah, if he was a powerful swordsman then his simple slash could generate a powerful shockwave. So he couldn't practice like he usually does.

"That's the reason why most of them will train their skills in their inner consciousness. Do you get it?"

"Yeah, still... This is your inner consciousness...? It's different from mine." Souta said while looking at the glittering stars around the space.

"Of course it's different. I died in the past so my inner consciousness got destroyed. All the stars that you see in this place are all fragments of the spells that I imprinted in this place." Saya explained to him.

"I see... So that's why I've been feeling some energy towards those glittering stars." Souta nodded and he looked at Saya. "So what should we do?"

"Of course, I'm going to fight you in this place. Don't worry I will not kill you because if I kill you here it will affect your real body." Saya said as she raised her finger. "One more thing, one hour in real world is equal to five hours in this place."

"Hmm...? 1:5 ratio. It's not bad." Souta said and tightened his grip on his sword.

"Ufufu, come and attack me." Saya chuckled and a sword formed in her hand.
