ah
heres how
1 go trial forest any level
2 back attack a monster
3 go back to engine scan 1
4 back attack again a monster scan 2
5 then attack again a monster scan 3
after that i think 1-3 address will shown up
get the first 1 and then freeze it to 1000
if you finish the dungeon with perfect star it works
if not do the same process
