"After you were born, I raised you in Japan." But I found out that he was unusual, too precocious, and could read Chinese and English books without any enlightenment as an infant...

I can only speak Neon language but I can't recognize it...

Although naughty, he is mature in mind.

When he was 6 years old, he was nearly kidnapped but was rescued in time by a bodyguard. At a young age, Karasuma Gaki was vengeful and ordered his bodyguards to kill the kidnapper and burn the house.

He found the kidnapper's residence, ordered his bodyguards to sneak in, and erased all traces of his near kidnapping.

All the details were erased, which made Karasuma Renya see a genius who was extremely suitable for the organization.

When he was 6 years old, he was brought to the base and handed over to Gin for 6 years of training.

Gin really treated Fuuhe's son as his own son and taught him with all his heart and soul.

In the factional struggles within the organization, Gin naturally stands on the side of Karasuma Gaki, and it will be smoother for him to take over the organization in the future.

After obtaining the code name, Karasuma Renya actually did not intend to let Karasuma Gaki carry out missions like Gin. He trained him to enable him to be able to protect himself in the organization.

Later, he was allowed to return to his daily life. Although Karasuma Renya didn't understand why he insisted on going back to school even though he had already mastered those subjects.

"When you first demonstrated [Lin Le Wu You] in the arena, I knew that you were extraordinary, and that your teammates also had extraordinary... talents."

Karasuma Renya suddenly mentioned his skills and teammates, and Karasuma Gaki's body suddenly tensed up, "You sent someone to monitor us?"

"Haha, don't worry, I'm not interested in you kids." Seeing that Karasuma Gaki looked a little nervous, Karasuma Ren'ya smiled.

Karasuma Renya knew about it when he was in Karasumagaki Kuniichi, but he just investigated it privately and did not show it to Karasumagaki in front of him.

"But... you seem different from them." Karasuma Renye looked at Karasuma Gaki with a smile, waiting for him to say it himself.

"Hmm." Karasuma Gaki's right palm released a cluster of sparks, "A little trick."

In fact, Karasuma Gaki's blood and gene samples have been preserved and studied for a long time. The person is smart and healthy, and does not contain any special substances.

"What is this?" Karasuma Renye couldn't understand. Although he pursued immortality, he always believed in science...

"Grandpa, is there any progress in Leia's experiment?" Since Shirley was captured as a successful case study last time, the experiment should have some progress.

Karasuma Renye pulled out a small box from the secret compartment inside the wheelchair. Inside was a capsule that looked the same as APTX-4869. "Indeed, there is. The drug developed by Shirley has a mortality rate of 99.99%. The chance of successfully rejuvenating is too small. Leia's drug, based on hers, has a rejuvenation rate of 50%. Both the appearance and body functions are restored to those of youth."

"50%, so low." There was no way his grandfather would take such a dangerous medicine.

"Haha~ This is already a huge research achievement. Shirley participated in the research for 4 years, but only made a useless poison. Now she is somewhat useful." Wanting to live forever is to go against the will of heaven.

Karasuma Ren'ya waited for decades and spent a lot of money to wait patiently, so even though Shirley had no results after 4 years of research, he still valued her and was very indulgent towards her.

Karasuma Renya has always been generous, and Shirley, who loves luxury goods, used to have an entire closet filled with luxury bags at her residence.

Even her useless sister would buy luxury bags and live in a house provided by the organization.

He even purchased real estate privately in an attempt to avoid the organization's surveillance.

Karasuma Gaki looked at Karasuma Renya, who seemed quite satisfied with the result, pursed his lips, and hesitated whether to say that he could...
