It was super tiring going up and down the mountain with Lyuei, she just wouldn't stop talking after I asked about Yesheon, and every time I got tired she'd give me some kind of medicinal pill.
It didn't take away my tiredness, but it gave me the energy to keep going, and amazingly before nightfall I managed to go up and down the mountain about 6 times, which is impressive considering I'm just a regular person.
Of course, all that effort left me with a lot of aches and pains, and on the 6th time I felt really sick from the excessive strain, everything was kind of blurry, I was drenched in sweat and exhausted, and all my muscles were hurting.
Lyuei tried to be cool and did some kind of healing technique that really helped, taking away a lot of the pain, and after that I went to take another bath to clean off the sweat and grime.
