Hua Zhen, Kesha, and He Xi had discussed the possibility of parallel universes in depth before. To be precise, it had been after Kesha's resurrection, when she learned Hua Zhen's secret.
The appearance of something as inconceivable as "crossing over" had further confirmed their theories. During their spare time upgrading Hua Zhen's Sub-Biological Engine, they would often pool their knowledge and make all kinds of deductions about parallel universes.
Hua Zhen's purpose in studying parallel universes was simple: he merely wanted to ease the regret of being unable to reunite with his former family.
Kesha and He Xi had equally clear reasons for researching it. They feared Hua Zhen might suddenly disappear again, just as he had suddenly arrived in this world. If evolving Hua Zhen into the ultimate form of the Main Biological World still could not provide him with sufficient protection, then should he truly "disappear" one day, the two queens could use their research to find him again.
The three of them had invested tremendous effort into it, and their enthusiasm had been considerable. With their abundant knowledge and wisdom, constant hypotheses and verification had indeed yielded impressive results in subjects related to parallel universes.
Yet who could have imagined that, at this moment, the mysterious person would tell him, "So-called parallel universes do not actually exist!"
This completely overturned the conclusions Hua Zhen, Kesha, and He Xi had painstakingly verified over so many years. Naturally, all the results of their research had become meaningless as well.
If, as she said, parallel universes did not exist, then what exactly was the other world called Earth where I lived in my previous life?
Countless questions flooded Hua Zhen's mind, but he could not foolishly ask the mysterious person such things. He could only mull them over in silence.
