Jack lost in 10-20 minutes against sulong Duke 1v1
Lost in minutes vs sukong dukes on the rooftop
That 5 days was because Jack didn't fight dukes at their full power
BTW Jack stamina =/= King stamina
Just cause King is stronger ,doesn't mean he has better stamina.
King ans Queen were never hinted or shown to be stamina Kings
You guys should stop this dumb logic "X is weaker thus all his stats are weaker "
