A barrier is set up above Medicine King Valley, preventing anyone from entering from the air or using sword flight within the barrier's range.
The opening of the Lianxin Realm is also the only time Medicine King Valley opens its gates wide.
After entering the valley gates, one must first traverse an extremely long mountain path before entering the valley proper. The scenery inside the valley is completely different from the outside. Outside the valley, the four seasons are distinct, with bitter winter lasting a full five months of the year, whereas inside the valley, it is like spring all year round, and the temperature hardly fluctuates much.
