Previously, Zhang Yanhang thought that if there were enough Third Tier Permanent Teleportation Channels to clean up consecutively, it would still require the most ideal conditions to achieve this. However, amusingly, Niger simply doesn't have that many Third Tier Permanent Teleportation Channels for him to clean. Fortunately, he managed to achieve this with the Fourth Tier Permanent Teleportation Channel.
Of course, it was just briefly achieved, as he could finish cleaning in at most twenty minutes, so it's not long-lasting enough.
Tens of thousands of various monsters surged towards Zhang Yanhang like a tidal wave, but as soon as they approached him, they fell to the ground like mosquitoes sprayed with insecticide, quickly crashing down onto the sand dunes, scattering large amounts of sand.
