Su Xin himself cannot use Haki, so naturally he cannot use tasks to enhance Enel's Haki.
"Then we can only enhance physical qualities, or... just use Enel to test and see what effect my Primordial Qi has on him."
Thinking this, Su Xin issued a task.
"Ding! Su Shen has issued a task: Please exercise diligently within two months, and on any day that you effectively exercise for more than five hours, you will receive an immediate reward."
"Reward: 1 point of Strength, 1 point of Physique, 1 point of Primordial Qi. This reward can be obtained repeatedly."
It should be less than a month before Luffy reaches Sky Island. Even if Enel repeatedly earns rewards through tasks, he can only enhance the three attributes by about twenty points at most, and the increase in strength would not be too exaggerated. It's uncertain whether he can defeat Luffy.
