The gap between the Sixth Rank and Fifth Rank was so wide that not even Jiang Li, a cultivator whose every Dao Fruit was unique, could bridge it.
Perhaps when Jiang Li attained perfection with the Sixth Rank Dao Fruit and fully integrated it, he might be able to do so, but as for now, it was absolutely impossible for him to kill a Fifth Rank using only the Sixth Rank's power.
Assuming he relied solely on his own strength and did not borrow the power of heaven and earth.
The natural world was full of all kinds of forces. If one could understand their principles and use them to their advantage, they could accomplish many unbelievable feats.
Just like how Jiang Li previously summoned the wind and clouds, causing the heavenly phenomenon to change.
If one forced it with True Qi, it would consume a tremendous amount, and even a Fifth Grade practitioner would have to use a Dao Fruit Divine Power to achieve this.
