Thanks for the chapter!
Surprised Vermeil isn't able to see through the invisibility or detect Lillian like her magic power, shifting in the air or something. Vermeil definitely enjoys flirting with MC. In any case, wonder if Lillian will still be there when potion wears off or when MC gets back. If she wakes up she should just borrow a shirt and pants before leaving through window. Or can go pervert route and borrow some that were used with MC's scent still on them. As for that T-Rex anyone know if that's bone or stone armor? Granted the weight will slow it down but it'll definitely raise the offense and defense along with potential moves. Question is whether the good guy is the one lying on the ground or the bad guy is. Granted it looks bad but Lex may have just put a lot of effort into his studies and magic rather than make a devil's bargain for power as don't know who attacked who first. Guess will find out next chapter.
