Using the 'Ring of Starlight' in the Hermit's Canyon was undoubtedly a suicidal act.
Previously, when he used this special equipment in the Star Corridor, it drew the attention of the stars.
However, at that time, the gaze of the stars was blocked by the power of 'Almighty True Knowledge', thus allowing Lin Xun to summon the 'weaker' Star Spirit.
But in the Hermit's Canyon, when he experienced a knowledge overload, he was shown the message [Here, you cannot glimpse at 'Almighty True Knowledge'...].
Somehow the stars blocked the gaze of 'Almighty True Knowledge'. Even his knowledge overload could not let 'Almighty True Knowledge' see him anymore.
If he were to use the 'Ring of Starlight' again without the gaze of 'Almighty True Knowledge' to protect him, he would instead attract the attention of the stars, and the creatures he summoned might be beyond his imagination.
