Upon choosing this skill, the names of Ziyun and Starlight lit up at the same time in the list, indicating that both pet beasts could be taught.
The ability was plucked from Earth attribute Pet Beast Round Bear but could be taught to Thunder attribute Ziyun and Dark attribute Starlight. Without a doubt, it was a universal, unattributed skill.
If both beasts can be taught, then there seems to be a question of who to teach.
Ziyun currently doesn't have any vision-enhancing skills. This skill does not conflict with its existing skills and can be used as a supplement.
Starlight has Night Eyes, so it has less demand for Insightful Eye, but the possibility of future skill fusion must be considered.
Undoubtedly, this skill can be fused with Night Eyes, and also, as it is a vision-enhancing skill, the success rate wouldn't be too low.
The ownership of a two-stars skill is a minor issue, but Xu Ran saw bigger problems lying within it.
