Qin Feng's method was simple.
With the means currently at his disposal, if he wanted to deal with the Successors of the Limit Break and Secret-Peering Grand Authorities, he could only wait—wait for a Time-Space Gate to open in one of the Blueprint Worlds under the Blue Star System while the other side's Time-Space Gate opened at the same time.
Then Temple Master-level experts from their side would board a Time Lightship, allowing Qin Feng to catch them on the Old-Day Battlefield...
But that depended far too much on luck.
Qin Feng still didn't know how to make Black Plum Big Li's luck attribute take effect on a specific target.
At least for now, Black Plum Big Li's luck authority hadn't unlocked any targeted luck effects.
So Qin Feng could only rely on other means.
Namely...

Through the Myriad Phenomena Divine Lamp, he could borrow access to many other Grand Authorities, and Qin Feng still had seven free uses left!
Through the Tracking Grand Authority, I can track down a specific target's exact spatial coordinates.
Although my current attributes and Divinity Limit aren't enough for me to directly track other Grand Authority Successors, tracking players from their Blueprint Worlds would be a breeze.
First, I'll track a Temple Master-level expert from their Blueprint World who's visited the Old-Day Battlefield, obtain their exact spatial coordinates, then use Extreme Love or some other means to control them...
Then I'll have them investigate the Secret-Peering Grand Authority Successor's exact spatial coordinates, and I can use the Disaster Grand Authority to bombard them to death from afar!
Clearly.
The Tracking Grand Authority wasn't very useful in Highest Heaven, because tracking a target who was also a Grand Authority Successor required an
