Level: Search for Shangri-la

This is my second release level. I participate in Advent Calendar 2021, but in fact, this level is not for Christmas. It took so many years for me to build this, and yet I've not completed it. At such time, I notice this event, and suddenly I decided to participate.
There are three levels. The last part is not included. I'm going to create the final one around 2023...maybe...

Because this is not for Christmas, it is a bit hard level..

Story:

Lara heard that there was an entrance to Shangri-la in the deep mountain of Tibet. Lara smell the adventure and departed in the afternoon of the day.
