"System, upgrade my Dragon's Roar Technique for me!"
As soon as Li Zhongnan's voice fell, half of the Gold Mine snatched from the Taihua Dynasty vanished in an instant.
Seeing this, Li Zhongnan secretly scoffed at the In-app purchase system, then proceeded to check the status of his Dragon's Roar Technique.
"Roar!"
An evil dragon's roar echoed, causing the entire system space to shudder thrice.
The power was absolutely astonishing!
Li Zhongnan, seeing that his mere shout had already caused the system space to tremble uncontrollably, could imagine if it was used against an opponent, it would probably blow up the opponent's own father.
Although this money was spent, it was well worth it.
The In-app purchase system may have been a bit of a rip-off, but it would never cheat him in this regard.
After upgrading the Dragon's Roar Technique to the max level, Li Zhongnan thought and returned to the outside world.
"Ancient Celestial Fiend, call Frost over."
