After breaking through the stratosphere, the Gemstone River had reached an altitude of over fifty kilometers above the ground.
The large Magneto-Europe Stone capable of supplying an entire city was running at full power.
Not only did it completely offset the planet's gravity in the already extremely thin atmosphere, it also let the Gemstone River keep accelerating with a "whoosh, whoosh, whoosh" like a real squid.
Its eight tentacles had nearly vanished from sight, leaving behind only long blue trails of light.
Boom!
Everyone on the bridge was pressed against the backs of their seats by the powerful acceleration.
However, even the weakest of the spacefaring passengers aboard possessed a second-tier extraordinary rank.
Their physical fitness far surpassed the Mortal Limit and was stronger than that of any well-trained astronaut. This little bit of pressure felt no different from a breeze brushing their faces.
Yet, not long after they broke through the stratosphere—
Crackle, crackle.
A sudden burst of flashing light appeared in the bridge's projection. They could clearly see blue electrical sparks crackling across the pristine white hull.
"R-Report, Captain!"
Then the somewhat timid voice of the ship spirit, "Hōshō," sounded in their ears.
"We just struck a powerful magnetic barrier. It clashed violently with the Life Magnetic Field I projected outward, but it will not affect normal navigation."
Evan understood. What they had just hit was likely the invisible, intangible atmospheric "ionosphere."
This atmospheric layer was the primary cause of auroras. Long-range radio communication also relied on refraction through the ionosphere, so it was hardly some great wonder.
Captain Olivia's True Sight Magic Eye had already seen through the nature of this minor incident. She nodded and ordered:
"Continue forward!"
"Yes, Captain!"
Very soon, the Gemstone River broke through the hundreds-of-kilometers-thick ionosphere in a blaze of sparks and
