First of all, when you come to the corona, you will see three stone pillars with white ore inside. Then we use the bow and arrow to hit the three targets, and the mechanism on the stone pillar will hide the ore. After hitting three targets, you can press and hold the "M" key to replace day and night. After the replacement, we will find that the target in the stone pillar appears again. Next, three attacks on the gem on the far right can untie the corona.
