Chapter 5: Veldora.

As we flew through the sky. We soon arrived at the entrance of the cave. Tsubone wasn't even frightened by the massive amount of aura and was even excited. I was also not scared as I had [ Trauma Immunity ].

I was about to slash the door wide open using my sword, but Tsubone noticed my movement and stopped me. She slowly opened the door using her strength and we both entered.

"Mikoto-chan, be careful."

Tsubone already noticed the massive amount of monsters and quickly made countermeasures if ever the time came, of course, it was only IF the time came.

"I know... You should not have followed me." I said as I pulled out my sword.

I noticed a slight presence underneath the ground. I killed it instantly while I was walking and identified it. It was one of Zentsu.

'A bug managed to get passed my radar? Yet Mikoto-chan managed to find it and quickly killed it without breaking a sweat. She will be a great assassin.'

I looked at Tsubone from the side of my eye and she looked pleased and wanted to say something, I ignored her and waved my right hand. She quickly responded and killed all the monsters in front of us in 5 seconds and there were over 100 monsters individually.

"Mikoro-chan. The monsters in this cave are weaker than expected and the ores are pure. Please be careful as we are getting near the Vldora." Tsubine said as she cleaned herself up and matched my pace.

"Then let's move."

I ran straight to where Veldora was sealed and Tsubone followed suit. Just like I had expected, all the monsters were decapitated and even their corpses could not be seen.

'Is this one of her skills? I think it's around the Unique Skill level. Is this how all the butler's power or is it only for Tsubone?'

I knew the power of the Zoldyck clan, but not to this extent. The power she unleashed was more than I could ever imagine.

Tsubone quickened her pace and went in front of me as the Magicules around us were getting thicker and thicker over time.

'This is getting too dangerous. Should I force Mikoto-chan back home?'

Tsubone started to worry as she has never faced a True Dragon and by the Magicule around her, she deduced that they were stronger than her by multiple times.

We stopped and saw a black dragon laying on the floor sleeping and a translucent barrier was surrounding him.

"Stop acting. I know your awake Veldora." I said while Veldora pulled his body up and looked at me with intimidation.

"I am Veldora. Wahahahha." He suddenly screamed making a huge gust of wind go to us.

"The two of you are quite interesting. How are you not affected by my presence?" Veldora asked as he tried to look at what we could do.

"What brings you, humans, here?"

"I'm here to get subordinates and you... Are the best that I could get as of now." I said which shocked Veldora and Tsubone.

"I'm a True Dragon, The so-called destroyer of Nations, The natural disaster of humanity, Veldora, and you want me to become your subordinate?" Veldora asked as he looked angry.

"The Thunder Berd and The Serpent Dragon... You... You know what I mean now don't you?" I swung my sword and cracks of space appeared out of thin air and pure darkness swallowed us as we were teleported away to my domain, [ Plaine of Euthymia ].

'So this is the domain where Mikoto-cha-no, Master Mikoto reside and train... Its... Wonderful.' Tsuboni was astonished but still had a clear attitude.

No one other than myself went inside my domain alive, but this time, it was an exception that even I can't avoid.

"This is my Domain. If you know how powerful the domain is... Then." I said as I looked at him with pure power in my eyes.

"Then how about we create a Soul Corridor?" Veldora asked as he looked at me.

'This is getting too dangerous.' Tsubone knew how dangerous a soul corridor is and quickly interfered.

"You might be a True Dragon, but the fact that the Young Master was named by an Awakened Demon Lord remains."

"Wahahaha~. Then who is this Demon Lord?" Veldora asked with full confidence.

"It is the Demon Lord of King of Darkness and Queen of Darkness," Tsubone said as she smirked.

"You're from the Zoldyck family, arent you?"

"Yes. What about it?" I said as lightning bolts started to appear and Tsubone activated her skills.

"N-Nothing. I just wanted to ask."

"Then do you agree?" I asked as I looked at him.

"Well, being a subordinate is still far-fetched, but if it's a Zoldyck, then why not." Celdora agreed as he looked at me with interest.

"Then..." I was about to say something, but he interrupted me by saying. "In one condition. We make a soul corridor."

'It seems he's not willing to listen.' Tsubone was ready to kill Veldora at his weakest point and Knock me out.

"Alright then." I pulled my hand up and said. "Zect." A magic circle appeared in front of us and half of it was color green while the other color white.

"What is this?" Veldora asked as he tried to see what its use was.

"Didn't you say you wanted to create a soul corridor?" I asked as Tsubone looked surprised, while Veldora was interested in the magic spell itself.

"How do I know it's safe? How about you explain first." Veldora asked as Tsubone calmed down and listened to my explanation.

"I was named by my father and had a soul corridor connected to him. I scanned it over and over again and over the years, I managed to create this spell. Which allows two people to instantly create a soul corridor, so as the two parties agree."

'This, This is... She is a monster... She is no longer a child.' Tsubone was even more impressed by my discovery.

"Zect," Veldora said as he grinned and the magic circle turned green on the other side and then turned blue. The soul corridor was instantly created between us.

A huge flow of mana came rushing at me and new, profound information started to come to my head. I already had the Extra Skill [ Sage ] and it helped a little to arrange the information in my head.

'The pain is too much, even for me.' I thought as I tried to calm down.

I didn't even flinch as I said. "Now, the next problem is that Barrier around you. Do not worry, I already know its abilities. Can I ask something?"

"Yeah, what is it?"

"Are your magicule reserves still coming out of your body?" I asked as I looked at him.

"Surprisingly no."

"Alright. Can you wait here until I find a solution for the seal? I made this small screen to make you see what I'm seeing." I said as a screen appeared out of thin air and a projection of what I was seeing could be seen on the projection.

"Well, I can, but everything?" Veldora asked and I realized what he was talking about.

"Not in bathrooms."

"Ok..."

"This is not goodbye. This simply sees you later." I said as I returned both me and Tsubone.
