Try switching to earth main and use the same team. It it much easier to do 140 with that team.

Follow exactly this video: https://www.youtube.com/watch?v=752g_juqQYg I can't exactly remember since it's been too long for me doing 140 but I believe you need kurenai to have a lower health than lee, which is why she was attacked instead of your lee.

I'm sure you know how to make kurenai's health lower than lee but if you don't just remove just remove some life magatama until the health is lower than lee's.
