If he could control the heart of darkness, and from there, truly control the entire Underdark, that would be a huge benefit.
This was also the reason why Su mo had agreed to Ye Ying's request to take over the umbriferous Sacred Palace.
As for the Union with Ye Ying!
He still needed Ye Ying to coordinate and integrate the power of the Underdark.
The Underdark world didn't only have the Underdark Sacred Palace, but also countless night God clansmen and other races.
Su mo carefully sized up the heart of darkness. It was well protected by the people of the umbriferous Sacred Palace.
Based on the current situation, the people from the umbriferous Sacred Palace had split into two hiding spots.
One was the ancient spirit Mountain range, where those people protected the darkness Lord.
One was the current group of people, responsible for guarding the heart of darkness.
