Much like the methods used by native creatures of the Youyun Plane to erupt with power in moments of crisis, creatures of the Wizard World and other planes possessed such methods as well—and in even greater variety.
For mages like Saine, they could burn the magic power and Mental Strength within their bodies to take a great leap forward in strength over a short period.
However, the consequences were extremely severe. Ending up with atrophied Mental Strength was already considered a fortunate outcome.
In more serious cases, it was not unusual for them to suffer a direct drop in level or die suddenly. (P.S. A mage's physique was famously frail.)
Knights could likewise overdraw the power of their bloodlines and cells, trading away their vitality for a brief eruption of strength.
Naturally, the consequences of doing so were also grave.
Either their bloodline would permanently dissipate, or they would suffer a drop in level, or remain in an extremely weakened state for a long time to come.
At least they did not need to worry, as mages did, about accidentally kicking the bucket.
Lunna and Nataya naturally had methods to risk their lives as well, but the target of the explosive technique Saine had developed through his research in the Youyun World was fat.
If the human body were compared to a flame, with the flame's temperature representing one's strength.
Then, to make that flame burn more fiercely in a short time, the right approach was to keep throwing firewood into it.
The explosive displays of ordinary knights and mages were equivalent to throwing their Mental Strength, magic power, bloodline power, and vitality into the fire as fuel.
Doing so could indeed make the flame burn more fiercely, but the price was burning themselves away.
Fat was a high-density aggregate
