Chapter 21: You Must Not Hide Anything from Your Senior Martial Sister

Not until he stepped onto the deck after leaving the cabin did Luo Yan still agonize over it.

"How could it be used like this?"

"Why was it used at the Marrow Cleansing Rank?"

Even without acceleration, the Marrow Cleansing Rank would only take about ten years; the Refining Mansion Rank could easily take more than two hundred years, and that's just for the Third Grade Golden Core requirement!

Since there's such a strong capability, why the hell didn't they use it to improve the grade of the Golden Core, damn it!

"You don't really believe it, do you?" the Kunlun Mirror said somewhat helplessly.

"Why shouldn't I believe it?" Luo Yan directly countered, "If it's fake, then I've lost nothing; but if it's true, the loss would be huge, okay?"

He said through gritted teeth:

"I'd rather she was just bluffing; otherwise, if this happens a few more times, my blood pressure is definitely going to explode."
