The ice crystal tunnel was full of traps, to begin with.
There were boulders, crossbow bolts, quicksand, holes, poison gas, and all sorts of other traps.
Liu Yan was powerful, and his body was extremely agile, but he believed that without the map of traps, even he would not be able to pass through the ice crystal tunnel safely.
As for the secret realm's map of traps, one could only obtain it from the enchanted puppets with special methods.
Without Liu Yan's heaven-defying talent Divine Extraction, it would not be that easy.
As for the enchanted puppets from before, they had all been stored by Liu Yan in his storage ring, making it even more impossible for the others to obtain them.
Thinking of this, he took out the trap materials that he had kept previously and returned to the ice crystal tunnel, rearranging them one by one.
At the same time, he added some spice to these traps.
