This is destined to be another lengthy research.
Afterwards, Sunan looked at the pitch-black branch beside him.
This branch is named the Black Key, which, as the name suggests, is the key to open the Black Forest.
During this period of research, Sunan has roughly mastered how to use the Black Key.
At the same time, he also discovered that the Black Key is constantly and slowly absorbing energy particles from the surrounding air.
It is estimated that it will take about three years to fully charge.
Based on this, Sunan speculates that the Black Forest is likely similar to the Tower of Starlight, opening only once every while.
And the next opening time of the Black Forest is most likely three years later.
"I hope it gives me some surprises."
Sunan murmured to himself, his eyes flickering.
After the incident with the Tower of Starlight, he no longer harbors any illusions about so-called wizard heritage.
