Well, giving insights was only one aspect of this Eternal Dao Lotus, so it would be still useful for him in a lot of ways.
He had to find a way to take it. Leaving it wasn't an option. Holding it was equivalent to holding multiple Primordial Origin Treasures in terms of Dao insights.
He closed his eyes. It was hard to look away from it since he knew its worth, but right now he couldn't do anything, so he would not show much interest towards it.
He had to find a way to break this detection array without alerting anyone.
It was almost impossible to do it, as he had to find exact nodes and destroy them at the same time.
Given that this array was a Grade 8 detection array, it was but a foolish dream to do so. The only way he could think of taking the Eternal Dao Lotus away was to pluck it while letting himself get discovered and teleporting away before anyone in the sect could react.
