At the time, Tian provided an update via satellite phone, noting that the team had already reached a depth of over 100 meters.

Due to the rising daytime temperatures, Tian and the team could only drill at night, and they made up for the sleep in the daytime, so for the final month of the expedition, they didn't see daylight.

Some members of the 21-person team left the expedition early, due to the harsh environment, but not Tian.

Upon his return home last month, he was 10 kilograms lighter, and his skin displayed a deep tan.

Collectively, the team had successfully managed to extract over 530 meters worth of ice core samples, which will be subdivided into multiple segments to facilitate the ongoing research conducted by Tian's team, as well as collaborative institutions both domestically and internationally. Additionally, a portion of the cores will be preserved for future research.
