Inside the mansion 

Frank looked at the barrier with a sly smile.

"Begin," Frank instructed.

[Activating the chaos star disintergration technique]

The technique specializes in destabilizing anything that operates on the foundations of heaven and earth energies.

That meant that there was close to nothing it couldn't destabilize.

"I wonder who created such a powerful skill," Frank pondered as he watched the system do its thing.

Time slowly went by.

On several occasions, Frank grew nervous about the old man's eventual return.

But he didn't stop

He had a goal in mind.

Soon enough

"shheee"

The energy barrier went down.

"go!!"

Frank didn't ponder anymore. He moved at his maximum speed towards the door into the old man's house.

He didn't know if the old man would have a way of knowing if the energy barrier was down, so he had to be fast. All he needed was a clue to the faceless mercenary companies' base of operations.
