1. Choose the option not to climb the mountain to continue developing the plot.
2. Find the photo on the table in the tent. The woman in the photo has the same glasses as her husband.
3. The heavy rain outside the tent was getting heavier and heavier, and the medical kit they forgot to bring when they left was still nearby.
4. Collect six suspicious points in the next scene, namely their skin color and exchange of clothes, mother's arm and the wound under the silk scarf, father's height and glasses.
5. Then we continued to find four suspicious spots on the husband’s body, including scratches on his face, tied arms, blood stains on his pants, and fragments of glasses on his legs.
6. Two options will appear at the end. You must choose to believe your parents, and then you can successfully pass the level.
