Gu Yuzhi is a child whom the Gu Family patriarch rescued and adopted early on, and his birth registration indeed lists his blood type as AB.

However, he has been healthy since childhood, with no hospital stays or surgeries, and rarely went for physicals. Only when he was entering university did the school hospital discover a mistake: he wasn’t AB; he was pure A.

He didn’t think much of it and never bothered to amend the details on his birth certificate, nor did he mention this trivial matter to his family.

Yet, since Bao Gucheng managed to dig out Xi Zuzi’s medical check-up records from childhood, it wouldn’t be difficult for him to find Gu Yuzhi’s school hospital records from back then.

But instead, Bao Gucheng publicly announced his blood type as the fake AB.

Men and women with AB and B blood type combined cannot have a child with O blood type.

Children born to parents with pure A and pure B blood types, however, might be O blood type.

In other words, among everyone present, only he knew clearly that Xi Zuzi had a high likelihood of being his and Sha Sha’s biological child!

Could it be that he, aside from that one wild night at the bar, was with Sha Sha before?

In a flash of insight, he suddenly remembered how Sha Sha gave birth to three sons for Xi Fengnan, binding her to the family entirely, letting her career go to waste, leaving her exhausted and depressed. During that time, Xi Fengnan’s business was booming, and he was constantly traveling, not having the heart to aid her through the hardship of raising children.

Back then, he went to Qingcheng to handle a case for someone, hesitating over whether to secretly visit her, only to unexpectedly learn that she had overdosed on medication during a depressive episode and was rescued in the hospital.

He didn’t hesitate for a second; he abandoned all his tasks and watched over her for three days and nights without closing his eyes once.

He stayed by her side until her life was saved, confirming she was safe before he finally fell asleep.

The length of that sleep he could not recall, but he remembered a long and vivid dream from that time!

What if that wasn’t a dream?

And instead, in their dazed states at the hospital, he and Sha Sha were overcome with... impulse?

Considering the timeline, Zuzi was born precisely ten months later.

If it wasn’t a dream, then he truly committed something shameful, twice!

Gu Yuzhi silently swallowed this overwhelming speculation, clearly knowing this matter must never be mentioned again, not for the rest of his life.

The medical report from the hospital must have already been destroyed by Bao Gucheng by now.

Bao Gucheng quietly covered up his past, not to save him but to protect Zuzi from being judged by the world.

During this period, he frequently felt jealous of Bao Gucheng, thinking that shameless wolf coveted Sha Sha, but now the truth was revealed: the big-tailed wolf in his heart only cared about Zuzi.

Moreover, he was willing to disregard conventions and use any means necessary for Zuzi!

He couldn’t help but feel inferior.

Faced with such a big-tailed wolf, even if the wolf was determined to be with his daughter, what reason did he have to stop him?

His mind cleared up gradually, and he first raised his voice, "Regarding the rumors about Zuzi, not only do we need to debunk them, but I need to find the malicious rumor monger!"

Everyone supported him, "That’s right, tonight’s fiasco, with hot air balloons and paternity tests, was definitely premeditated and disgraced our Gu Family. This person surely has ulterior, dark motives. We can’t foolishly fight amongst ourselves; we must listen to Young Master Gu, thoroughly investigate, and sue them for defamation!"

Shangguan Wanwan pursed her lips and shook her head, pouring cold water on the situation, "This might be hard; you don’t understand legal procedures. It requires gathering a lot of evidence..."

Gu Yuzhi glanced at her and walked towards Yin Hu, "I’ve received quite a few anonymous harassment and threatening texts recently; can you help trace their origins?"

Yin Hu replied, "Professor Gu, why didn’t you mention this earlier? This is quite easy for us to trace."

Gu Yuzhi: "..."

Indeed, why didn’t he trust Bao Gucheng earlier and swallow his pride to ask for his help, leading to the current dire situation?
