As people who know both Karasuma Renya and Kuroba's surnames, both of them know what this means.

Hakuba figured out why he had been investigating the Karasuma family before but could never find any clues.

It’s because I simply made a mistake in the direction of my investigation!

Karasuma does not represent a family at all, but the patriarch of a family!

And the surname Black Feather, could it be that Black Feather?

The figure of that person could not help but appear in Bai Ma Tan's mind.

At this time, Qin Zhibo, who realized that something was going wrong, quickly asked, "What happened next? How is the family?"

The researcher continued: "Later on, the family grew stronger and stronger. On the basis of 'Kuroba', descendants extended surnames such as 'Kuroiwa', 'Kurosaka', and 'Kurosawa'."

Kurosawa?

Qin Zhibo suddenly remembered that Gin's real name was Kurosawa Formation.

In other words, these situations are very likely to be true...

The origin of Kuroba's surname is Karasuma Renya?

No, it might just be a coincidence.

After all, Kuroba is not a very uncommon surname in Japan, and it certainly does not all come from this.

Qin Zhibo could only convince himself in this way.

But the more you convince yourself in this way, the easier it is to form a psychological hint in your heart and you have to pay attention to it.

Once the surname Kuroba comes from Karasuma Renya, then Kuroba Toichi, Kuroba Kaito...

Even Kudo Yusaku and Kudo Shinichi are both of Kuroba's blood, but they just changed their surnames later.

And not only Kuroba, but also Sera...

Damn it!

Is there any way to confirm whether this is true?

Suddenly, Qin Zhibo had an idea and thought of a way.

He quickly asked Mary, who was also thinking blankly next to him: "Where is Noah's Ark?"

"Noah's Ark..." Mary responded, "I put it in the car."

"Get it right away, I need it urgently!"

Seeing Qin Zhibo's serious expression, Mary did not dare to delay and walked out of the ward quickly.

After a while, she brought back the computer and USB flash drive.

Qin Zhibo turned on the computer, and an artificial intelligence AI in the image of Hiroki Sawada popped up on the computer desktop.

"Hiroki, you remember that you developed a DNA tracking system before, right?"

Sawada Hiroki nodded, "Yes."

"Can you still use that system now?"

The current Sawada Hiroki is the result of lightweight code, and many unnecessary functions have been deleted.

However, after thinking for a second, Sawada Hiroki still nodded, "It's okay..."

Qin Zhibo: "How to use it?"

Hiroki Sawada: "As long as the DNA data is sent to me, I can perform DNA tracking. Even if it spans hundreds of years, I can track the target's ancestors."

"On the contrary, the DNA of their descendants can also be inferred from the blood of their ancestors."

Hiroki Sawada's words made Mari and Masumi Sera look shocked.

After getting along with each other for the past few days, the mother and daughter have already felt that this AI's ability in data analysis is at least a thousand times better than humans.

But they didn't expect that AI could actually track human DNA.

However, Sawada Hiroki is not bragging.

He developed a DNA tracking system during his lifetime. By chance, he obtained a blood sample from Jack the Ripper and traced that Jack's descendant was his adoptive father Schindler, which led to his murder.

"I don't have to go through the trouble of tracing my ancestors. I only need to compare the DNA of two people..."

…

Half an hour later, Qin Zhibo appeared at the private hospital where Conan had stayed.

After explaining the situation to the doctor whom Kudo Yusaku knew, Qin Zhibo successfully obtained Conan's blood sample.

In order to develop an antidote as soon as possible, Kudo Yusaku asked the doctor to save some blood samples while Conan was injured.

After getting the blood sample, Qin Zhibo returned to St. Thomas Hospital.

And Mary here has also drawn blood.

Under the arrangement of the hospital doctor, their blood samples were sent for DNA testing.

After getting the DNA test report, Qin Zhibo first analyzed it with his naked eyes.

Judging from the paper test report, the identities of the two are not related, and there is no possibility of any relationship.

Mary on the side also breathed a sigh of relief when she saw the contents of the report.

She had just learned the reason for conducting this test from Qin Zhibo.

Assuming that the mother of Karasuma Renya, the boss of the black organization, is Sera and her offspring is Kuroba, then the offspring of the two must be related in DNA.

Now, the paper report given by the hospital has denied this possibility.

Next, let’s look at the so-called “DNA tracking system”.

When Qin Zhibo "fed" the data from the two DNA reports to Noah's Ark, the little figure of Hiroki Sawada on the table entered a state of thinking with his eyes closed.

Qin Zhibo and Mary were also sitting in front of the computer respectively, waiting with serious faces.

At this moment, time stretched infinitely in the hearts of the two of them.

They are like candidates waiting for college entrance examination scores to be released, staring at the screen motionless.

Especially Qin Zhibo, he didn't even dare to think about what it would mean if it were true.

Karasuma Renya is the common ancestor of Sera and Kuroba...

Although Qin Zhibo doesn't believe that Conan or Mary and others are "black", if this was part of Karasuma Renye's plan from the beginning, it would be very scary.

With Karasuma Renye's ability, she might have some bloodline control ability...

For example, Mary's sister, Elena, is now a member of the organization.

Could this be because...

Qin Zhibo was a little afraid to continue thinking about it.

All the answers can only be left to Sawada Hiroki to reveal.

…

The wait this time was very long, both in terms of the level of inner suffering and the reality.

After waiting for 15 minutes, until the computer keyboard became hot to the touch, Sawada Hiroki slowly opened his eyes.

"The results are out..."

"According to the results of the DNA tracking system, the probability that these two blood samples have a common ancestor is..."

"84.7%."
