Let's head back upstairs and go in this direction.
Go up two steps and look left. You can see enemies and some materials ahead. Don't bother with the door on the left since we don't have the key.
After obtaining the materials, turn back and head up the stairs on the left.
After coming up, there's a new save point. The boss battle is just ahead.
Save your progress, then head left. There are still items to collect on the right; there's a material chest behind the box.
Next, let's fight the boss, Bi Yuan Sect Leader's Remains. He doesn't have any special mechanics, so let's just look at his skills.
Blue Light Attack 1: Pay attention when he twirls his sword; it will suddenly shift into a blue light attack.
Black Light Attack 1: He places his sword behind him to charge up, then unleashes a black light attack.
Black Light Attack 2: He raises his sword to charge with black light, slightly faster than the previous attack.
Red Light Attack: Like many bosses, he likes to leap and flip to perform a red light attack.
His attack patterns are quite limited, cycling through just a few moves, so the difficulty isn't high, though his damage output is somewhat high. After defeating him, you'll obtain the weapon "Tianxuan Bronze Sword".
