When this phenomenon repeated itself a hundred times in a regular manner, Meng Chao finally realized that the Ancients were using a mysterious weapon to deal with the beast horde.
He originally thought that it was something like a cell disintegration cannon.
Through the ultra-high frequency vibration, it triggered the resonance of all the cells in the carbon-based life form.
Then, with the resonance that was constantly magnified, the complete life form was reduced to divided cells.
However, whether it was the compound eye of the ancient insect or Meng Chao's own super vision, they could all see objects on a bacterial level.
Even if they were instantly broken down into cells, it was impossible that there were no signs at all. Not even the slightest trace could be observed.
Meng Chao observed the disappearance of hundreds of insect-type monsters.
However, he could not find the reason for their disappearance.
