Li Yao was certain that at the current stage, apart from himself, it would probably take years for anyone to truly be able to use the Infinite Range Arrow.
Because the Infinite Range Arrow appears to be a skill, but in reality, it is like the Sonic Exploding Arrow, a profound secret of archery.
It involves not merely archery, but also requires special eye assistance equipment to exert a unique Pupil Skill.
Yes, the Infinite Range Archery required a Pupil Skill, because even Li Yao, although boasting the Titan's Eye and enhanced by some equipment attributes, could only achieve precise shooting over hundreds or thousands of yards using a sniper rifle's scope. With a bow and arrows, aside from the skill's range limitation, the main issue was the accuracy.
Of course, powerful Machine Crossbows were another matter.
