Lara's expression changed slightly. "Without my help, it's impossible for you to open the vault."
Tyrion casually looked at her and said offhandedly. "There's no need for you to worry about it, I will figure it myself."
Lara's beautiful face was expressionless as she stared at him with some sort of glare. It appears this vault was very important to her than which is more reason for Tyrion to keep it to himself.
"70-30, that's the least I can go, if you still don't accept it, then you shouldn't blame me for being ruthless." Her face turned cold as she radiated massive amount of waves from her body, she was actually prepared to fight I've eit with Tyrion.
Tyrion tilted his head and a smirk formed in his lips. "You actually want to fight me over the vault? It seems it's more important to you than I thought. Alright, 70-30 it is only on one condition."
"Which is?"
"I get to choose among the loot first."
