Feng Fan cringed at the ridiculous technique name the moment it left his mouth, but he quickly pushed the thought aside. There was no time to dwell on it, not when he realized the absurd amount of spiritual qi it was draining from his body. The technique itself didn't consume much at its core, but the stronger the affected targets and the more numerous they were, the greater the cost to maintain it.
He desperately drew upon the energy stored within Little Brick, rapidly absorbing spiritual qi to sustain the technique. But even that wasn't enough. 'Did Your Grandma Teach You That?' was burning through his reserves faster than he could replenish them.
'Five seconds. That's all I can hold it, assuming no one dies in the meantime,' he calculated.
If things went according to plan, though, the number of enemies under the technique's influence would steadily drop as they died, lightening the load and extending the time he could maintain it.
