The jade box was lustrous and felt warm to the touch.

Wang Chen tried to open the box directly but found that the lid and the body seemed to have fused into one, making it impossible to lift.

Although brute force could sometimes work miracles, he felt that if he tried to force it, he would likely destroy this treasure.

After some thought, Wang Chen decided to inject a thread of mana.

He was extremely cautious, fearful of triggering any potential restrictions, so he controlled his power very steadily.

However, when Wang Chen's mana entered the jade box, it was like a mud ox disappearing into the sea, without even the slightest sound or sign of movement.

Could this be another piece of junk?

Wang Chen felt somewhat dejected and attempted to inject a greater amount of mana.

As a result, the jade box instantly emitted a faint red light, and the box itself began to heat up slightly.

There's a way!

Wang Chen immediately increased the mana input to thirty percent.
