Go to arcade or practice mode. Select Shujinko with all of his special moves. When on stage, do the move "Throw Spear" (Scorpion's Spear move). When you bring your opponent to you, press the D-pad in the opposite direction of your opponent + Y, then immediately do the same pop up after that. You should have done that only two times. Next, immediately press Right + B, X(2), L, B(2), L (the "Big Slice" combo). This should give you a 10-hit combo and most of the time 49% damage.
