Li Fan blinked his eyes, switching Qiongqi's night-vision capable eyeballs. He saw that within the carved out, perfectly squared stone chamber hidden within the mountain, there was a statue of a Xuantian goddess. Beneath the statue was a stone casket, which indeed was empty—likely the sword box had been hidden inside it before. On the outside of the stone casket was a mathematical puzzle.
'Xuantian's sword intent speaks, heh heh, boy, try solving it yourself, eh? Solve it and you can become my disciple. I'll even pass on to you two sets of sword scriptures for fun.'
Li Fan sweated, he had just intended to leave a note saying he was here and nothing more, could it be that he still couldn't escape the fate of doing math puzzles? However, fortunately, he also had a foundation in mathematics. After some calculating with his fingers, he managed to solve the problem in about the time it takes an incense stick to burn.
