The Upper Realm.

Shi Lang arrived in the upper realm and stood inside a hall. The hall was made of white marble. It was pristine and flawless. Not even a speck of dust could be found. The most significant change was the purity of spiritual energy. 

The energy rushed through his pores and entered his body. It was completely new, and the young man felt he had never known what spiritual energy was like. He tried to access his space ring but sensed a weird restriction. At this moment, a calm voice sounded, "You will need to be at least in the realm of a Spirit Immortal to access your space ring." 

Shi Lang was confused and looked around. Suddenly, he spotted a figure waving at him from behind a door. Shi Lang was surprised but quickly walked through the door and said, "Senior, can you please tell me where this is?"
