"Immediately search all the people with the surname Li in the capital, over the age of fifty, both men and women. Then, identify those who have been abroad or have had contact with foreigners. Those on the death list should also be checked."

"Also, you investigate the Warrens family yourself. I want to know whether the current patriarch has an Eastern or Western appearance!"

Bai Chuan was stunned: "Sir, you mean..."

Even though Bai Chuan was smart, he didn't understand what Gu Yibei meant by his sudden instructions.

Gu Yibei raised the corners of his lips and smiled evilly.

He threw the things in his hand onto the table, leaned back in his chair and crossed his legs.

"The Warrens are an ancient aristocratic family in the West, all of whom have Western white faces. But according to Grandpa's description of Nannan, Nannan's father has an Asian face, and Nannan also has an Asian face. This means that on Nannan's father's side, a young man or young lady from the Warrens family married an Asian woman decades ago."

Asians all have oriental faces.

Ji Zhinan's face was incredibly beautiful, so beautiful that it was hard to believe it was natural. It was too perfect, like a work carefully sculpted by God, so perfect that it was hard to find fault with it.

Double eyelids, big eyes, a high nose bridge, a cherry mouth, and more importantly, her facial features are very three-dimensional, with a high-end beauty.

If her father is a mixed-race, Nan Nan has inherited the three-dimensional facial features of the West, but has not abandoned the black eyes and black hair that an Oriental should have.

This also explains why Ji Zhinan is so beautiful.

"Young Master Warrens chose to come to the capital, most likely because it was the hometown of his father or mother."

There are many countries in Asia. Gu Yibei excluded other countries and decided to check China first.

"Also, he's the young master of the Warrens family, but when he met Nan Nan's mother, he chose the alias Li Yuan. When people choose aliases, they often include a word that's very important to them."

In other words, either Li or Yuan, one of the characters is very important to Li Yuan.

Gu Yibei wasn't sure it was Li, but there were countless people with the character "Yuan" in their names, so finding it would be like looking for a needle in a haystack. Although he wasn't sure if they were searching in the right direction, they could only start with the surname Li.

Gu Yibei explained it calmly and logically. Bai Chuan, who was confused at first, immediately understood everything after listening to it.

Sure enough, only the smart Mr. Gu could think of so much.

However, there is one thing that Baichuan cannot understand.

"Sir, I understand you wanting me to investigate the Li family, but... why do you want me to confirm whether the current Warrens clan leader has an Asian face?"

Gu Yibei picked up the phone on the table and checked the time, then stood up and spoke calmly while tidying his clothes.

"The Warrens family has always had difficulty accepting people with skin colors other than white. Li Yuan has Asian ancestry but is a Warren, which is very rare in the Warrens family."

Therefore, if the current chief of the Warrens has a Western face, then Li Yuan may have really died in the civil war that year; but if he has an Eastern face, Li Yuan... may be the current chief of the Warrens.

Bai Chuan looked at Gu Yibei and said, "The Warrens family is too secretive. The current patriarch has almost destroyed everything that happened 20 years ago. He has never appeared in public in all these years, and no one knows what he looks like. It will be difficult to investigate him."
