Thanks for the chapter!
MC is acting like an arrogant idiot. He's focusing too much on granny without taking a good look at the SP(?). She's gotta have enough skills to be able to handle the small fry while Granny protects Li and only moves in to take care of any big guns while the SP watches Li and their back. In any case, I bet whoever is on the plane is someone important enough to warrant one of the family members picking them up while trying to avoid attracting attention with a big crowd. Guess we'll find out after the duel.
