Qiao Yu: "..."

Alright, now he was certain, the man in front of him was definitely his biological father.

In this world, the only person who could be more infuriating than him was his own father.

"Okay, Dad, let's not talk about this anymore, let's go see Mom." Qiao Yu quickly changed the subject.

"Alright... huh? What do you mean, *our* Mom?" Qiao Anqing was taken aback.

Seeing this heartwarming father-son scene, Irene smiled with relief, then quietly withdrew.

As they approached the cabin, a gentle woman's voice came from inside.

"Honey, is that you and the boy back?"

"Yes, honey, this stinky kid is so tall now!" Qiao Anqing said with a chuckle.

"Great! Just wait a moment, the food will be ready soon!" The voice rang out again from inside the cabin.

Qiao Yu was a little excited, his heart was pounding.

After so many years, was he finally going to meet his mother?

He wondered if his mother looked like his idiotic uncle?

Filled with anticipation and a bit of nervousness, Qiao Yu slowly pushed open the door of the cabin. Qiao Anqing quietly took a few steps back.

The room was filled with smoke, and white fumes were everywhere. Qiao Yu was stunned for a moment, almost thinking he had arrived in the Heavenly Court.

Bai Shixia was wearing a gas mask, unable to see her face, stirring something in a large pot with a wooden spatula. Inside the pot was a large mass of dark, unrecognizable stuff. Even with Qiao Yu's sharp eyesight, he couldn't tell what it was.

"Son! You've grown taller!" Bai Shixia was also a little excited when she saw Qiao Yu, and rushed over to hug him. "You must be starving! Don't worry, the food will be ready soon!"

Qiao Yu: "..."

"It's okay, Mom, I'm not hungry, take your time."

After Qiao Yu finished speaking, he considerately closed the door of the cabin again.

Then he came to Qiao Anqing.

"Dad, is Mom refining pills in there?"

Qiao Anqing's mouth twitched. "You think I've been married to your mother for so long, why haven't I eaten her cooking more than a few times? It's because I don't dare to."

Qiao Yu was silent.

True, who was Bai Shixia? She was the eldest daughter of the Bai family, a top power in the Ninth Universe. She had people to take care of her every need, never lifted a finger, so it was normal that she couldn't cook.

"Then... why do I feel like Mom thinks her cooking is delicious?" Qiao Yu asked the question in his heart.

"Ha! That's easy!"

Qiao Anqing's face revealed an extremely proud look.

"Every time she finishes cooking, I immediately devour everything, not letting her taste a single bite, and desperately praise how delicious it is. Over time, she really thinks she's a culinary genius."

Qiao Yu: "..."

"Dad, you're such a sly old fox."

"Alright, while your mother's food isn't ready yet, ask me anything you want," Qiao Anqing said.

Qiao Yu looked at the slightly overweight middle-aged man in front of him.

"Dad, actually, what you control is the Law of Time, right?"

Qiao Anqing nodded.

Qiao Yu had actually guessed the truth in his heart for a long time. Only by mastering the Law of Time could he explain why his father had been involved in so many events in mythical eras.

"The seal on Kaiji Star, the brain-computer interface chips, were those all your doing too?"

Qiao Anqing nodded, then shook his head again.

"It was me, and it wasn't me. Do you know the famous grandfather paradox?"

"No."

"Simply put, if you travel back in time and kill your grandfather, then without your grandfather, you wouldn't exist, and without you, you wouldn't travel back in time to kill your grandfather, so your grandfather wouldn't die. This is a famous paradox about the Law of Time."

"Basically, even if you master the Law of Time, you can't directly change anything."

"Forget it, it's too troublesome to explain. I'll take you to see it for yourself."

Qiao Anqing raised his hand, and the River of Time appeared before him and Qiao Yu. Qiao Anqing stepped in, and together with Qiao Yu, entered the River of Time.

...

"The most basic curvature in GR is the Riemann tensor, which is formally a 4*4*4*4 high-dimensional matrix, where 4 represents 3-dimensional space + 1-dimensional time."

"The Riemann tensor can be divided into the Ricci tensor and the Weyl tensor."

"Among them, the Ricci tensor describes the space-time distortion caused by matter, and the Weyl tensor describes the space-time itself apart from matter..."

In a complex and precise laboratory, a younger version of Qiao Anqing was writing and drawing in the laboratory, and all of his research was related to the curvature of space-time.

Looking at the complex and appalling formulas in the notebook, Qiao Yu, standing beside the River of Time, suddenly felt that he might not be his biological son.

"Theoretically, the greater the speed of an object, the slower time passes. Once the speed of an object reaches the speed of light, time equals zero, which means time stops! Then... is it possible to achieve faster-than-light speed?"

The younger Qiao Anqing stayed in this small laboratory every day, single-mindedly researching these incredibly profound things.

Qiao Yu watched him work tirelessly for an unknown amount of time. One morning, Qiao Anqing exclaimed in surprise.

"I've done it!"

Qiao Anqing put a bunch of strange and precise instruments on his body, and then activated them.

But instead of traveling through time and space, Qiao Anqing arrived on a strange planet.

Qiao Yu couldn't hold back anymore, because he saw Bai Shiyan when he was young in the picture.

The following story was about Bai Shiyan going to conquer Kaiji Star, and Bai Shixia insisting on following him.

After arriving on Kaiji Star, Bai Shiyan's strength was completely sealed. First, he was beaten up by Qiao Anqing, and then his younger sister Bai Shixia was tricked away by Qiao Anqing.

Qiao Anqing took Bai Shixia to Kyoto University. While studying at the university, the two successfully sparked a romance.

Not long after, they held a wedding and had Qiao Yu after their marriage.

Except for Bai Shiyan, who was drowning his sorrows in alcohol, the next days of their family of three were extremely happy.

But seeing this, Qiao Yu noticed something was wrong.

"Dad, that's not right, is it? At this time, shouldn't you be researching the brain-computer interface and chips that can enter the Reverse World?"

Qiao Anqing smiled.

"That's later. Keep watching."
