Yang Chan's Martial Arts Cultivation had broken through to External Refining of Iron Bone Perfection, just as he'd hoped. He had even deployed the Fusion Martial Seal Nine Oxen and Two Tigers, which combined his Ox Demon Martial Seal and Tiger Demon Martial Seal. After feeling the power boost it provided, he didn't try to push it any further.
It wasn't suitable to use such power within the Cyan Yuan Sect. Doing so offered no benefit and risked exposing his true Cultivation.
His Cultivation was his ultimate life-saving measure, and he wouldn't reveal it easily.
Besides, he was only seventeen and had already reached External Refining of Iron Bone Perfection. This fact alone would surely bring him a lot of trouble, and trouble was the last thing Yang Chan wanted.
Displaying an External Refining Copper Skin Cultivation was already impressive enough. Anything more would be a bad thing.
Therefore, he chose to keep a low profile.
