章 423: The Mysterious Box

Cook Barn did not dwell on this point. He shifted his gaze and pushed his wheelchair forward.

"You've done well during this period. The Dark Knights and the survivors have joined forces to deal with us. The army has suffered repeated setbacks. The improved potion you developed has helped us a lot..."

As he spoke, Cook Barn came to a wall in the reception room. He stretched out his palm and pressed it against the wall.

"I believe that the Dark Knights cannot stop our rise."

"Click..."

A hidden secret door was opened.

"This place used to be one of the secret research institutes of the Meteorite Company. After the disaster came, I brought it with me to transform this place."

Behind the hidden door was a long main passage.

Cook Barn pushed his wheelchair into the passage.

Fang Heng looked at Ni Shengtao and controlled the Tyrant form to follow him into the passage.
