From the current situation, this measure should be able to exert some effect.
The [Magic Energy Thermal Ball] is continuously consuming mana, generating a heat field that gradually warms up.
This field does not have a fixed range or shape, it's merely a zone of warming.
It will also be affected by external weather, just like now, under a medium-sized sleet.
The warming field's range further shrinks, and the warming speed barely keeps pace with the dissipating speed.
The area behind the cargo hold is all wet, including the water droplets that have accumulated on the warriors.
In such conditions, trying to make the warriors feel warm is impossible.
The Heat Ball can only play its maximum role in a relatively enclosed environment.
However, as long as it can slow down the loss of heat, it is already enough for Zong Shen.
The heat converted from magic energy will replace a portion of the warriors' body heat loss.
