It wasn't that Lin Zhen had never faced swarm tactics before. In fact, he had faced billions of enemies on countless occasions and always emerged victorious with ease.
The problem was that this time was different. Not only could he not kill the enemies en masse in an instant, but they also had the capability to resurrect endlessly, making the situation rather troublesome.
The enemies weren't just any riff-raff, the weakest amongst them were at the peak of quasi-sovereign.
Although Lin Zhen's current strength meant that a peak quasi-sovereign could not truly harm him, they could still gradually drain his power.
Endless depletion would eventually exhaust even the steadiest man.
Once exhausted, he would be beginning his descent to defeat. The Sovereign Strongmen could still cause some minor damage to Lin Zhen, not to mention the Jade Buddha Sovereign had yet to truly take action.
This style of combat was a cycle of death, slowly grinding an individual to their demise.
