Many of Liu Chang'an's doubts had already been resolved.
Phoenix blood indeed held an irresistible allure for him. What had happened in Everlasting Palace back then—when Shangguan Dandan had blended among the palace maids to pass herself off as one of them and fish dragons out of troubled waters—had certainly been a contributing factor, but the root cause was the mutual attraction between the most powerful extraordinary lifeforms.
Besides knowing of Liu Chang'an's existence, Tesla had learned of Phoenix's arrival before he had. After discovering that Su Mei possessed the Phoenix bloodline, she began making arrangements.
The reason Su Mei had ultimately been able to give birth to Zhu Juntang was not only the biotechnology she claimed to have borrowed from Tesla, nor merely the essence of Liu Chang'an's blood that had remained in Mrs. Karnstein. At its core, it was because Su Mei herself carried the Phoenix bloodline—perhaps a clone of Shangguan Dandan, or something like one of her feathers.
In other words, even without Tesla's help, now that Shangguan Dandan was here, as long as she was willing to provide some form of assistance, Liu Chang'an could even have a second, third, or fourth child with any other woman.
It would probably consume one of her feathers or something. Liu Chang'an remembered that quilt she had made from countless Phoenix feathers.
If he really could have that many descendants, Zhu Juntang, that little Mie dragon, definitely would not be so arrogant anymore. Every day, she openly declared that Liu Chang'an had only her, this one Mie dragon, as his heir, and that he had to let her ride on his neck and lord it over him.
The only remaining question was whether Phoenix's arrival had been a local event, or an incident involving a traveler from another plane.
