Chapter 635: If the caliber were even slightly smaller, I wouldn't feel at ease.

Walking inside the huge seed vault, everything was suffused with a science fiction hue.

It was like stepping into a massive spaceship carrying humanity's hope, fleeing into the universe, with the sounds around being monotonously terrifying, only the hum of the cooling machines at work.

Removed from human settlements, it was also free from the maelstrom of war and other unstable elements.

The remote location, harsh climate, and being home to polar bears were disadvantages for human habitation, but these factors kept the "seed vault" safe from various external threats.

The perennially frozen ground was perfectly suited for the long-term storage of seeds, unaffected by temperature fluctuations. The air in the vault was replaced once a year during winter, but if for some reason that couldn't be done, the permafrost would still keep the seeds fresh for decades.
