Chapter 1: reincarnation
M.C [so your a R.O.B and your letting me reincarnate in tensura as a slime with one power of my choice]
R.O.B [correct, so shall we get started]
M.C [alright, I want the powers of Ji Ning from Desolate Era at his peak when he becomes an Eternal Omega Autarch]
R.O.B [alright, but his power will be scaled down so that you are just the most powerful in the world of tensura]
R.O.B [that's right since you chose Ji Ning's power you will have a sword that you will customize the look with your new body] Author's note: the body and sword's looks are the same as the cover page and he will have the clothes
After M.C customizes his body and sword
R.O.B [ you will appear in veldora's cave when rimuru meets veldora, now off you go]
M.C appears in veldora's cave and wanders around and meets veldora when rimuru learns how to see
M.C [I finally found y'all]
Veldora [and who are you]
M.C summarizes what happened to him
Rimuru [really your also a slime and a reincarnater]
Veldora tells them about the world
after rimuru and veldora go through all their drama and the naming starts
Rimuru [then veldora your last name will be tempest it's another way to say storm]
Veldora [then your be rimuru tempest and he shall be frost tempest]
Frost [well then I could destroy your prison but why don't we have rimuru eat you and analize then the unlimited imprisonment so that we won't have to worry is we encounter in against even if the possibility is next to zero that we will]
Veldora [hmm that does make a lot of sense, alright then]
Rimuru [but if you can destroy it then aren't we already good]
Frost [I forgot to mention but is your predator works the way I think it does then after you analyze the unlimited imprisonment then you should be able the use it]
Rimuru [ohh it makes sense now]
Rimuru eats Veldora and they leave the cave
