Sun Wukong and Shen Lang were accompanied by another person, Princess Ziying of Ziying Star.
Ziying's identity was revealed by Shen Lang; it seemed that the participants in this Holy Book Academy assessment were all royal members of various planetary races, mostly wealthy or noble, with Sun Wukong being an exception.
Ziying changed her black clothes into dark green, and removed her veil, which was Sun Wukong's request.
Having someone covered in black scarf and clothes was indeed strange, so this was more normal.
The large lake where Sun Wukong and Shen Lang were was precisely the gap of the fourth barrier.
To cross the fourth barrier into the fifth layer area, one must go through the large lake, which housed numerous water monsters, with the monster fish Sun Wukong previously caught being a minor character.
Originally, when they arrived last night, Shen Lang wanted to cross the large lake into the fourth layer area, but Sun Wukong persuaded him otherwise.
