Chapter 173 Ceres_2
Long before Legion's era of cosmic-scale development, scientists were developing super materials that could replace spacesuits. Space Suits became the solution at the time, offering constant temperature control, insulation, radiation protection, antibacterial, anti-contamination, and antivirus properties, and when paired with other device systems, they made short spacewalks possible.
Now, MSPM Space Suits can provide emergency protection in different cosmic environments and have become a must-have for the wealthy.
Of course, these things are expensive. The most critical synthesis polymer formulas are patented by various corporations. Systems like AVNDS's nanoscale setups are virtually invisible invincible shells to the naked eye.
