The 19th episode of the travel variety show 'Go to the End! Solo Tour' on Channel S and Channel E will reveal the cast embarking on a 'merit-building' project on the eve of the Paektu Mountain Heaven Lake tour.

On this day, comedians Kim Dae-hee, Kim Joon-ho, Jang Dong-min, Yoo Se-yoon, and Hong In-gyu visited Yanji, China. Kim Joon-ho personally introduced a restaurant serving Yanji naengmyeon, which had taken first place at a world naengmyeon competition, and the members enjoyed a meal of buckwheat naengmyeon and guobaorou together.

After the meal, the members checked the weather for the Paektu Mountain Heaven Lake tour scheduled for the following day. When they heard there was a 35% chance of rain, concern spread among the members. In particular, Kim Dae-hee emphasized the need to verify the sincerity of the 'merit-building' efforts.

Meanwhile, Hong In-gyu revealed that he had gone to donate blood. Kim Joon-ho then raised doubts about whether it was an act just for the show, and Hong In-gyu, protesting his innocence, unveiled a photo certifying his blood donation.

In addition, Yoo Se-yoon gave massages to the staff. Kim Joon-ho lightened the mood by joking that while Jang Dong-min usually carries the staff's luggage, he only does so for pretty women.

The outcome of the Paektu Mountain Heaven Lake tour and the 'merit-building' project can be seen in the 19th episode of 'Go to the End! Solo Tour,' airing at 9 PM on the 10th.
