The range of this fire had to be sufficiently wide.
Not tens of meters, or hundreds of meters, but nearly 3,000 miles.
All 3,000 miles along the shore of the lake had to be ignited.
And allowed to burn for an hour!
In such a large area, ordinary methods would not work, not to mention that the water vapor around the lake was so dense that it had turned into mist.
After Su Jingxing learned of this method, he pondered over how to start a fire as he traveled.
Now, there was no need. Once he activated his divine power, Command The Winds and Fire, he could even ignite the entire Copper Lake, let alone just 3,000 miles.
The only thing to worry about was that there were aquatic devils in the Copper Lake and they were very powerful.
If Su Jingxing were to set a fire by the lake for an hour, there was a 99% chance that he would lure the devils out.
