Chương 538: Chapter 249: Treasure Vermilion Bird Tail Feather, Achieving Great Achievement in Body Refinement State! (Two-in-one, 10,000 words)_5

When the simulated energy was sufficient, Su Xing silently recited:

"I choose to bring out Body Refinement Great Achievement cultivation level... as well as the insight of Thunder's Origin (Minor Achievement)!"

As the words fell, a prompt sound came from the simulator.

[You have successfully brought out Thunder's Origin Insight (Minor Achievement), spending 1.5 billion points of energy, with 35.53 million points remaining.]

As the prompt sound ended, two streams of mysterious energy surged into Su Xing's body.
