Chapter 150: Observation Room Upgrade

Holding the hammer taken from the workbench, Chen Xin struck the ice accumulation in the shelter repeatedly, unable to avoid feeling exhausted and panting heavily.

Supporting his waist, Chen Xin leaned against the wall inside the shelter and took a deep breath. Although the oxygen content in the shelter was always high due to the oxygen generator and the planting greenhouse, this location was practically considered as external, making him breathless and panting after the ice removal session just now.

Reaching into his pocket for an oxygen bottle, he opened the protective mask on his face, took a few breaths through his mouth and nose, and felt much better before putting the protective mask back on and straightening up.

"Whew, how long will this ice removal take?" Chen Xin couldn't help but sigh. The ice was so thick that the small hammer in his hand couldn't effectively break it, only knocking off some ice fragments with great effort.
