Tai Yu did not spend much time looking over the blueprints.
While the various parties were "going through the procedures," he mainly sought to understand the situation, asking about the causes and consequences of the previous conflict and the "technical malfunction" until he had a fairly complete picture.
The chain of cause and effect was clear and simple.
It was because Zuo Can, whose fate remained unknown, had last been located in the Gray Blue Eye Demi-Plane. Then, during the subsequent investigation and questioning, the management here—including Shi Fan—had all spoken vaguely and failed to provide a clear explanation.
On top of that, the other suspect, Wei Su Yi, had taken her "little lover" and fled to the Qiankong Star System. With the murder of a direct-line descendant still unresolved, the Zuo Family, a God-Favored Family no less, could not swallow the insult. They had therefore called upon their connections in the Myriad Gods Hall and the Supreme Council to establish an investigation team and come here to investigate the case.
They called it an investigation, but it was practically an expedition to demand an accounting. No matter what, they intended to make Shi Fan give them an explanation.
Shi Fan's account had never changed: she claimed that she had not been at the scene at the time and had only returned afterward to clean up the aftermath. As for Wei Su Yi, Shi Fan had asked her before, and Wei Su Yi had said she did not know.
Besides, Wei Su Yi had indeed come with only her "little lover" at the time. Given the strength the two possessed then, they were simply not enough to threaten Zuo Can and the two Celestial Domain bodyguards at his side.
The Zuo Family had actually believed that explanation for a time.
