"Extreme Challenge" has been running for five years, and the six guests have spent a lot of time on the show.
Since they are all actors and singers, they naturally cannot participate in every episode.
The fifth season of "Extreme Challenge" underwent a major cast change, as Zhang Yixing, Huang Bo, and Sun Honglei had to leave early due to their schedules with other shows and movies.
They were replaced by Reba, Yue Yunpeng, and Lei Jiayin. Although the effect was good, it still could not match the original cast.
Moreover... these three are just too silly...
Reba is adorably dumb, Yue Yunpeng is stiff, and Lei Jiayin is clumsy.
With both Huang Bo and Huang Lei absent, the Extreme Challenge six-member group was left with only the half-sly, half-foolish Little Pig, while the rest were just a bunch of silly people.
The show effect became bizarre—watching a group of 'fools' doing a show made the humor feel too one-dimensional.
