Hey guys!

Here is a lineup my friend with only 350k power used to beat level 50 Nature Training Lightning

Although it does require some expensive ninjas (full breakthrough Killer Bee and Sasuke Rinnengan)

use Bee's def/res reduction passive

round 1 after Yagura's standard copy Mabui so you can get immortality for the next 3 rounds and make sure to copy her again every 2-3 rounds (after yagura's standard)

round 2 first use fire main mystery and then Sasuke on Cee

Make sure you always have 80 chakra before using Sasuke's mystery
