Days quickly passed.
Life on the slave trading ship was monotonous and dull, Su Jie spent his time studying the Mysterious Shadow Secret Technique besides occasional inspections.
"Divide!"
In the cabin, Su Jie moved his hands.
The shadow behind him suddenly stood upright, transitioning from a two-dimensional plane to a three-dimensional figure, the pitch-black shadow gaining luster, morphing into Su Jie's form.
Controlled by Su Jie, the shadow agilely ran back and forth in the room, its movements indistinguishable from a real person's.
"It worked."
Su Jie nodded in satisfaction, the shadow now under his control could basically be used in combat.
Although Su Jie's talent was poor, he did not pursue complex variations; having a substitute to take hits was enough to meet his expectations.
As for controlling several shadows at the same time, Su Jie did not even consider such things.
