Nuwa was not exaggerating.
There were many types of advanced technologies integrated on that special service spaceship of the aliens. Those technologies could be used as points of references.
For example, there were material technologies, reactor technologies, engine technologies, artificial intelligence programming technologies and so on.
There was even a miniature gravity field generator. When the device was started, it would generate a gravity field within a small area. Thus, gravity could exist in the interior of the spacecraft. This definitely belonged to the realm of futuristic technology.
In addition, a quantum communication device was installed in the alien spaceship.
