Li Younan carried a walkie-talkie and after saying a word to Liu Li and Zhizhi, he continued to climb upwards.
As the altitude increased, the air thinned, and the drone's power and battery significantly diminished.
Although the drone Li Younan bought was the top of the consumer-grade models, it still didn't reach professional or industrial levels.
And with Galongla Snow Mountain's peak altitude surpassing 5,000 meters, the drone struggled to fly but still barely kept up.
In fact, upon reaching this point, the distance to the summit wasn't very far.
As he climbed higher, the mountain, permanently covered in snow and glaciers, had a snow depth unseen at the bottom.
Li Younan had to pick solid glacier spots to climb upward, making his way from the front ridge to the side ridge, reaching the col.
At this point, the slope had become much gentler, continuing along the ridge line upwards, and in a few hundred meters he could reach the summit.
