For the first time, Du You discovered the numerous functions of his Mucus Swamp spell that he had previously overlooked.
It was able to burn, and the burning rate was very fast. Moreover, copious amounts of poison would erupt during the process of burning. Du You did not know how powerful it was, but the scope was definitely as large as that of high-level magic.
After all, the range of his Mucus Curse was already quite extensive. The poison it spread could cover an area several, or even a dozen times, larger.
He was not sure about the strength of the poison once it spread out. His Mucus Swamp possessed rather potent poison. Without specialized antidote or poison resistance, creatures of his own level intoxicated by it would hardly be able to resist. As for those of lower level, like the soldiers disguised as robbers last time, they were immediately poisoned to death.
"Hehe, that's correct." Du You chuckled awkwardly.
