"If killing is a sin...then let's have more of it!"
Above Lu Ping'an's head on the huge tree, there were still numerous withered corpses hanging.
Since he had turned over this trump card specifically prepared for the beast swarm and Beast Tamer, he naturally had to use it to the extreme... The ceiling was already densely covered with dry corpses, their life force becoming Lu Ping'an's spoils of war.
The doubled giant tree and its expanded attack range were impossible to avoid. Any obstructions turned into hanging corpses on it.
The reason it was only doubled, and not the extreme threefold, was not that the "ceiling" couldn't be higher and stronger, but because the "load truck"
had reached its limit first.
Noah's Ark is Guan Xinxian's battlefield and also uses the same source of "class doubling" ability, but both have a lower limit (2 times) and a shorter duration.
