Netherworld King's plan was a very simple open strategy.
Soon, the commanders and the generals from the other eight branches also realized what was happening, and even though they understood, they had no way to counter Netherworld King.
This was the very definition of an open strategy.
To put it simply, in the aspect of climbing the Shenxuan Fire Tree, Netherworld King could afford to be patient, but the people of the Shenxuan Fire Sect could not afford to delay.
Although they would outwardly suppress the people of the Black Fire lineage together, in the end, only one person could remain on the Shenxuan Fire Tree, and no branch could possibly cooperate with peace of mind.
Therefore, they had to occupy a higher position faster than the other branches, so they could use the more concentrated power of the Fire Dao Law on the upper reaches of the Shenxuan Fire Tree to stop other branches from climbing up.
