Often, it took Qin Feng several months to completely cleanse a single star system that had been converted into a steel fortress and deliver the final blow.
Refining the Machine Soul Core afterward also required a considerable amount of time.
By the time he had completely absorbed over thirty of these star-level Machine Soul Cores, Qin Feng's power underwent a truly explosive surge!
The height of his Immortal Tower had skyrocketed from its initial 70,000 light-years to a terrifying 700,000 light-years!
Seven hundred thousand light-years!
This scale far exceeded the scope of an ordinary star system. Even some massive galaxies with vast territories only had diameters of this magnitude.
Of course, this was only the Immortal Tower's true height within the Subspace.
If it were projected into the physical Cosmos, a giant tower spanning an entire galaxy wouldn't actually appear. Such a sight would be too exaggerated and would violate the fundamental laws of the Cosmos.
