Cultivation is just so scientific!

The view was from a high angle overlooking the land, and what made his scalp tingle was that he didn't see the edge of the world but only the entire Beishu Continent and some islands near the Beishu Continent, beyond which lay the ocean.

Even knowing that this land was vast, he had no idea that a photograph taken from such a high altitude would capture only the Beishu Continent.

At this height, in his previous life, one could have captured the outline of a planet.

What shocked him even more was the curvature of the earth. He had believed the earth was flat, based on the data returned from numerous failed rocket launches that had been analyzed by the IBM z15.

But according to this image, the earth still had a curvature, albeit very slight. If the land beneath his feet was still a sphere, he couldn't even imagine how large this planet must be.

He shook his head, realizing that his original satellite plan had to be abandoned, because based on this image, he needed to overturn all previous space research from his former life and establish a new theory of space tailored to this world.

He was not short on time. Currently in the Foundation Establishment stage, he could live two hundred years, and once he broke through to the Golden Core, his lifespan would extend to five hundred years.

He had plenty of time to reinvent a space theory that conformed to this world, but this would definitely not be achieved swiftly, so he decided to put aside his yearning for space for the time being.

However, there was an alternative method: using drones at an altitude close to the Thirty-Three Heavens, some ten thousand meters up, to set up temporary low-altitude satellites.

Few cultivators were willing to approach ten thousand meters, mainly because it was too dangerous—cultivators' control over such heights was not as precise as his.

Most cultivators did not venture above three thousand meters in the air. Awe of high altitudes began from the early stages of being a cultivator, and only those in the Golden Core stage or higher ever ascended to the Thirty-Three Heavens.

Given the scarcity of cultivators at the Golden Core stage and higher, plus the vastness of the sky, a drone fitted with array formation patterns to conceal spiritual energy fluctuations could communicate with the ground using only the radio waves of the previous era.
