This strange force field shape did not follow the principles of fluid mechanics. The water twisted and pushed aside ahead did not spread outward; instead, it was piled up and compressed behind before being released, naturally creating a forward-driving force that propelled the Dragon onward.
This propulsion mechanism was unlike flying through the air, where breaking the speed of sound meant overcoming the sound barrier. Beneath the water, the Dragon easily broke the sound barrier of three hundred meters per second and could continue accelerating. In theory, it had no upper limit.
Using the Distortion Field for propulsion had another advantage: silence! This was a higher-dimensional spatial alteration, with neither the mechanical noise of propellers nor the sound of cutting through water. Naturally, sonar could not detect it.
It could also ignore all floating objects and living creatures in its path, because they would be pushed aside together by the Distortion Field. After the Dragon passed through, whether fish or shrimp, they could continue swimming as if nothing had happened.
Unless the obstacle was too large, exceeding the guiding limits configured for the Distortion Field. For example, if it rammed directly into the middle of an adult blue whale, or challenged the hardness of the seafloor to see whether the Distortion Field could push the Earth aside.
In such situations, the Dragon would simply "crash" to a stop. The boat being destroyed was a minor matter—after all, a Kryptonian could not be damaged by the impact. But there were other passengers aboard now, and they could not withstand the jolting.
After all, the women currently seated inside the Dragon were ordinary flesh and blood. They could not endure such acceleration or the torment of suddenly coming to a stop. To make the gravity-urn-based damping system capable of allowing free movement
