if i can kill you once, i can kill you a second time

"what dangerous method?" leng rongrong and tang luo said in unison.

at this time, there was no other way. even the most dangerous method could be tried.

it was a last resort.

"i have a special weapon here that can raze this place to the ground ... i asked for it from your second father, chen lan, last time. perhaps it can blow lord fourth unconscious." nan si said.

leng rongrong: " ... then you're going to drag us down with you. to die together? "

" that's why i said it's a dangerous way, " nan si said. " it can make everyone faint. we'll see who wakes up first. "

"get lost!" " damn it! " tang luo cursed.

" no, i have another way. i heard it from qin ruyan. he used to treat an amnesiac patient and used a method to restore his memory. "

nan si said in all seriousness.

"what is it?" leng rongrong dodged mo linyuan's attacks while looking at nan si in anticipation.
