"System, how did Rimuru gained his vision?" I asked as I was as blind as a mole.
["It was with the use of {Magic Sense} that Veldora gave him, but you can just use your Reiatsu sense, that I will fix it to act as the {Magic Sense}."]
Using it, I began to see things.
'I never thought I'd be so happy to see things again. Hmm? My body has changed.' I looked at me.
["Your body has adapted to the Host's needs."]
My body was black instead of blue. Shrugging my non-existent shoulders, I decided to search for Veldora.
'Hmm. Veldora must be in the deepest part of the Cave... Or Dungeon.' I thought before going to the path that went deeper and deeper.
Until I reached a huge lake.
"Now the issue is getting across the lake. Rimuru passed it after he acquired the {Water Propusion} skill." I concentrated and jumped in the water, then I swallowed a lot of water and spit it using my mouth, sending me through the lake.
[{Water Propusion} Skill added.]
I used this skill to get across the lake, aftet doing this, I fell down and saw a huge dragon.
'So this is Veldora. He is way bigger than the anime showed.' I looked at the Veldora.
"Cna you hear me, small one?" Veldora asked.
"Yes, I can." I said while looking at him.
Oh~. You are not scared by my apparance. This is nice. I haven't had a visit in three hundred years, since it was the time I was sealed." He lamented.
"Hmm. Who are you?" I asked.
"Let me introduce myself. My name is Storm Dragon, Veldora. I am one of the only four True Dragons that exist in this world." Suddenly he began to laugh.
'What is so funny?'
"Hey, you are curious. Slimes usually are low-ranked monsters that don't think, but you have self-awareness. Are you Unique?" He asked.
"Unique?" I asked myself out loud, trying to remember what it means.
"Unique refers to beings that possesses extraordinary abilities." He answered my rhetorical question.
"Yeah, you can say that I am something like that." I said. "Now, you said that you were sealed-." I was interrupted.
"Hah! Glad you asked. It was three hundred years ago. I sort of turned a town into ashes by mistake. So someone came looking to slay me. It's certainly true that I underestimated my opponent a bit..."
'I'll let him tell his history. Poor guy, he is a Dragon King and really prideful, but was kept here for three hundred years.'
"... I started putting my full strength into the battle partway through, but I still lost. You may be wondering if I am so strong and still lose, my opponent was strong..."
'I was not'.
"... And it was. It was someone known to the humans as a hero blessed with divine protection. She overpowered me with her Unique Skill, {Absolute Severance}. And then, she sealed me using {Unlimited Imprisonment}. The hero called herself a Summon." Veltora finally finished his history.
"So you have been here for all this time?" I asked.
"Yes. And I am pretty bored." He said after he became depressed.
"So... Why don't we become friends?" I asked, expecting him to lash out.
"What?! A mere slime proposes friendship with me, the feared Storm Dragon?!" He screamed.
"Forget it, then." I said before turning to walk away.
"W-Wait! D-Don't go! No one said I didn't wanted to!" He screamed while turning his face.
"So... What do you think?" I asked.
"Yes, well... If you insist... I guess I'm willin to think about it." He said while placing his claws together, like he was embarassed.
'A true tsundere. I escaped from a yandere, straight to a tsundere. I guess this is a preparation to when I meet Mikasa.' I thought before jumping forward.
"Then it is decided. From now on we are friends." I said.
"W-Well, all right. I'll be your friend. You'd better be grateful!" He said.
"Hey, friend. I may have a way you get you out of here. It will require me to keep you inside my stomach, making my skills weaken and possibly destroy the {Unlimited Imprisonment}. What do you think?" I asked.
"..." He became quiet.
"..." I became quiet.
"Hahahahahahahahahaha!" He laughed really loudly. "That sounds intereting! Please, do it!" I'll entrust my entirety to you!" He said.
"Then let's-." He interrupted me.
"Wait, let me give you a name. To indicate that we stand in the same level. As you don't have a name, the name I give you will be a blessing. The name you give me will be a family name. So give me a cool name." He said.
"*Sigh*. What about Tempest?" I asked since it was the same name Rimuru gave him, it should please him.
"Tempest, you say?!" He screamed.
"Don't like it?" I asked.
"It sounds fantastic! As of today, I am Veldora Tempest!" He exclaimed. "And you will be Kuroku Tempest." He said.
"Okay. Then I shall eat you." I said before I used the {Predator} and swallowed him up.
["Would you like to analysis the {Unlimited Imprisonment}?"]
"Yes." I said while nodding my non-existent head. "Now I have a personal Dragon to guard my Kingdom."
'And great... Now I have to eat all this grass and magic crystals I can find in this gigantic cave since they can be useful. *Sigh*. This is going to be a long grind.'
