Cairo didn't waste the chance he had made. His Nightmare Worms have a strong effect on the soul, it can lower his enemies' fighting capabilities by a lot
However, it still has one major flaw. When Cairo first uses the worm to Davin, the worm was noticeable and was easy to discover. It can easily sneak up on the enemies but once the enemy felt that something is wrong with them and inspected their bodies, they would discover the worm
Unlike before, the worm cannot be seen by the naked eye anymore. However, it was still not that hard to find the worms if one tried to look for them
Thus, Cairo only has a limited time. He doesn't have even a single second of it to waste. Fortunately, he already deactivated his sand armor that gave him a faster speed. He easily reaches the weak but numerous acolytes
