"M-Martial arts?" Lihua was confused. "But Lu Bojing is a doctor.."

Zhao Weisheng smiled. "That's because he has been raised as one by the man you called Yang Mingshen."

Lu Bojing stuttered. "Y-you know about my family?"

He glanced at him. "Yes. I knew your grandfather. Your father too. Lu Geming was your grandfather, and Lu Quan was your father's name. They had assisted me when I was forming the Underworld. The Lu clan was a prestigious family. They have been training in martial arts for centuries. They had their dojos to train students. When I heard about your strength, I instantly thought about them. Only the Lu clan's bloodline descendants had such strength."

His gaze was slightly glassy as he reminisced about the old times.

"Lu Geming and I had similar ideologies. The Jiang family did horrendous deeds in the Underworld. It was absolutely disgusting. Neither me nor Lu Geming approved of this. It was tyrannical. I proposed that we would overthrow them and take control of it. And apart from that, I needed power. A lot of power.." He silently clenched his fist.

Lihua softly said, "To free Grandma and be with her and your children, right?"

He smiled. "Yes. I am surprised she told you everything. It was our tightly-guarded secret, and I believe she would have kept silent about it all these years because I was here."

She sadly nodded.

Zhao Weisheng patted her head. "She must really trust you a lot."

She sheepishly grinned.

Zhao Weisheng continued. "So, we joined forces. Lu Geming, I and the Cheng family. The Yangs at that time were neutral."

Lihua widened her eyes. "You know the Yang family too?"

"Yes. Yang Mingshen. His father must be Yang Cheng, right?"

She nodded.

"I had seen him once when he was a little boy. He was around Weizhe's age. The Yangs didn't outrightly lend us their support. To Yang Yingjie, Yang Cheng's father - the only thing mattered was their own medical research. As long as it wasn't affected and nobody interfered with their business, they wouldn't oppose us. But more or less...they were on our side."

Lihua's mouth twitched.

Why am I not surprised?

Mingshen is utterly selfish and only thinks about his lab and research. It's in the genes!

Lu Bojing asked, "H-How was Grandpa?"

This was the first time that he was learning about his family. He had mixed feelings. As long as he remembered, he had always been alone. No mother, no father. So, he didn't feel any connection with them, nor with the Lu clan even now. It wasn't emotional. He was simply curious about his roots and lineage.

For Lu Bojing, his family started and ended with Yang Mingshen, his benefactor.

Zhao Weisheng slowly said, "Very just. They had joined their skills to perfection. Their strength wasn't a joke."

Lihua wondered. "But how did they become so strong?"

"The strength is not supernatural. It's the way they trained. Have you heard about Yin Yang?"

Lihua sheepishly grinned. "No...Is it some secret technique?"

Qingqing, who was comfortably seated on her lap, looked at her in disdain.

This human can only give wrong answers.

Lu Bojing shook his head. "It isn't a secret technique. It's a concept of balance. Basically, it says that everything in this world consists of Yin and Yang. They are two opposite but complementary forces that need each other to exist. For example, day and night. Anything which is bright, moving is Yang. Anything that is dark, still is Yin. They are opposites. So a day is Yang and a night is Yin. Both are in contrast, but the world cannot function if either of them is absent. Similarly, light is Yang, and shadow is Yin. Shadow cannot form without light, and light cannot shine upon something which isn't dark."

Lihua beamed. "Oh! I understand now."

"Yin Yang is also used in traditional Chinese medicine. Boss had taught me about it. Our bodies also have both Yin and Yang. An illness occurs when either Yin or Yang's flow is disrupted, and the balance between them tips off. Chinese medicine usually restores this balance to treat the illness with acupressure and needles."historical

Zhao Weisheng nodded. "Correct. Yin Yang is also the basis of the Lu clan's martial arts. The balance between offense and defense. They have learned to keep their internal Yin Yang forces in balance as they move. Tension and relaxation must follow the natural course of Yin Yang. They have devoted centuries, practicing martial arts like this. And thus, this practice reinforced their muscles and tendons greatly at their DNA level. Every descendant was strictly told to continue martial arts, and at one point in years, it almost became genetic to be born with such strength."

Lihua brightened. "Oh my God! Bojing, your clan is so cool!"

She took his hands in hers and giggled. "Your hands look so dainty, but they hold so much power!"

Lu Bojing stammered and blushed.

Zhao Weisheng asked, "You say you work with Yang Mingshen?"

"Yes.."

Lihua nodded. "He took him in when Bojing was ten years old."

"Then there are high chances he knows about your clan history."

"Why?"

"Simply because of how the Yang family is. They don't show any meaningless kindness for nothing. He took you in because he must have known about your family. It makes more sense if he taught you martial arts and about Yin Yang."

"He-he did."

"Yes. How could he let you go if he knew that you are a descendant of the most powerful martial arts clan? How should I say this.." he coughed, "The Yang family has a habit of collecting rare and interesting treasures. But you don't have to feel bad about his intentions. You must already know how he is, living with him for years."

Lu Bojing was frightened and furiously nodded his head. "V-very dangerous and mean.."

Though he also greatly admired and respected Mingshen as much as he feared him.

Lihua fumed and hugged him. "Don't be scared of him. I will always protect you!"

Lu Bojing burst into tears with her kindness.

She looked at Zhao Weisheng and asked, "So, why was the Lu clan annihilated?"
