Zhang Bin was not worried about Little Lucky Star being discovered, because the Thunder Pool naturally generated miraculous talismans.
Moreover, the talismans in his Thunder Pool were exceptionally unique, as they could contain the Orange Thunder.
Therefore, even cultivators with extremely powerful clairvoyance abilities can't penetrate it.
As for Divine Sense, it naturally couldn't enter. When the passage opened, the thunder would burst forth, or absorb it inside.
Then it would immediately close.
Also, any Divine Sense not belonging to him entering the Thunder Pool would be destroyed by the thunder.
So, as long as Little Lucky Star doesn't come out, no one would know Zhang Bin has such a magical pet.
In fact, not only the Thunder Pool but also the Dragon Pool has the same capability; the enemy's Divine Sense cannot enter.
This is because equally miraculous talismans on the Dragon Pool's walls allow it to have spatial properties, producing water and ice.
