# Chapter 092 Back then
"Is it warm?" Bai Yan asked in a low voice, his eyes fixed on the hot tea in Cheng Yu's hand.
Cheng Yu nodded and took a sip of tea. The warmth of the tea spread across his tongue, with a hint of sweetness. "Hmm."
When Yu Lan saw Bai Qinghan come in, he immediately stood up, like a student being punished by the teacher.
Wow wow wow, why is Bai Yan’s father here too?
He had heard about Bai Qinghan's deeds before, so when he actually saw him, he felt timid.
"Luo Qi, go play with Dabai first, and the rest of you come with me." It was his doing that Yu Lan and Li Hengyu appeared in the manor.
Bai Qinghan took the six of them up to the third floor and walked through the corridor to the end. He took off the ring on his ring finger. The pattern on it matched the eyes of the snake vulture statue on the table.
The moment the ring was pressed, a crack opened in the wall behind the table.
?
Bai Yan and Bai Lishu looked at each other and could see shock in each other's eyes.
They had lived here for more than 20 years and had no idea that the Bai family had a secret door.
However, they were curious before why there was a sculpture of Bai Qing Hanqi Beast in the house. It was so weird.
Bai Qinghan did not explain immediately, but took them into the mysterious space.
The moment the last person steps through the door, the wall automatically returns to its original state.
Warm yellow light poured down, dispelling the darkness in the room and making the entire space suddenly bright.
There are several bookshelves placed around the room, and various books are neatly arranged on the shelves.
There was a large round table in the center of the room, and on the table was a red crystal the size of an adult's fist.
"This is..." Bai Yan walked over and looked at the crystal carefully.
The surface of the crystal sparkles with an alluring glow, and through the thin surface, one can seem to see the deep texture inside.
Cheng Yu was attracted and stepped forward. His purple eyes trembled slightly, and his pink and white fingertips fell on the protective device outside, forming a sharp contrast with the enchanting red color.
It's his.
"These are Cheng Yu's tears, or to be more precise, his energy." Bai Qinghan's voice was a little hoarse.
No one expected to get such an answer.
"How is this possible? Even I have never cried such big pearls." Yu Lan looked at him in disbelief.
Only clams that have lived on the seabed for tens of thousands of years can raise it.
"This crystal is mixed with Cheng Yu's blood, so it's so big. The Bai family has kept this secret for a thousand years." Bai Qinghan didn't know at first.
This secret was revealed to Cheng Yu shortly after he was born, just before his father passed away. That was also when Bai Yan had just arrived at the Bai family.
Bai Yan hugged Cheng Yu, and he leaned quietly in his warm arms, his expression indifferent, showing no sadness or joy.
"Cheng Yu was not born to his parents, but was cultivated in an artificial womb through gene transfer experiments." Bai Qinghan said.
Li Hengyu looked puzzled. "I've speculated about this before, but the gene transfer experiment isn't complete yet, is it? And isn't the incubator still being researched for in vitro embryo culture?"
If these two experiments had been successful twenty years ago, wouldn't the current scientists' research be a joke?
Bai Qinghan flipped through a photo. The background looked like a laboratory, and a sleeping baby was lying in a small cabin.
"Is this... my sister-in-law when she was a child?" Bai Lishu judged based on the baby's hair color in the photo.
Bai Yan's jaw was tense, his lips pursed into a line, and no one knew what he was thinking.
Bai Qinghan continued, "It was indeed imperfect back then, but the energy of the crystal was disappearing bit by bit, and at that time a special person appeared, so they decided to take a gamble."
The result was naturally that the bet was right, but Cheng Yu's body functions were not complete.
His body was so weak that his vital signs could only be maintained by instruments. Later, Li Qingzhu joined the experiment, and it took nearly a year to stabilize him.
"My dad also knows about this?" She always thought that her father was a son-in-law of the Bai family.
Bai Qinghan rolled his eyes at her before speaking, "Have you forgotten what your grandfather's family does?"
After hearing this, Bai Lishu realized that her grandfather's family was engaged in biological research.
In fact, Bai Qinghan was deceived by Li Qingzhu's gentle temperament at the beginning, and he immediately assumed that he was a young master from a scholarly family.
Bai Qinghan was worried that Li Qingzhu's family would not allow her to have anything to do with the Bai family, which was known for its fighting and murderous nature, so he took her back to the Bai family.
Unexpectedly, when the head of the Li family came to visit the Bai family and saw his son, he realized that his alpha was this member of the Li family.
The two families had already had an engagement, and he even felt that Li Qingzhu was deliberately not telling him.
Let’s get back to the topic.
"Then why didn't you bring Cheng Yu back to the Bai family at that time?" Bai Yan asked the question that had always been on his mind.
When Bai Qinghan knew this secret, he also asked his father, and the answer he got was that he could not interfere with his growth.
No one can interfere before Cheng Yu turns eighteen, unless his life is in danger.
Later, it was Li Qingzhu who told him that a member of the Li family had once returned from the future through a wormhole, and that special person was this member of the Li family.
Under certain special circumstances, wormholes can form a space-time vortex, through which humans can travel to different points in time and even explore other space-time dimensions.
Bai Lishu pointed at himself and asked, "So that's why you weren't surprised then?"
When she brought Bai Luoqi back and told Bai Qinghan about this, he looked calm, and she thought she was making too much of a fuss.
"Yes, that's why I said you are very lucky. It is very dangerous to travel through a wormhole, and not everyone can be safe." Bai Qinghan was really grateful at that time. Maybe it was destined.
The universe is so vast. It not only contains the ten major galaxies where humans live, but also some places that cannot be reached by current human technology.
The space-time vortex will not exist forever, which means that there will not always be special points for traveling through time.
That person tried at least hundreds of thousands of times before he could accurately return to another point in time in the same dimension.
As Bai Qinghan spoke, he entered numerous passwords to unlock the crystal's protective device. Only then did they see a palm-sized black box next to the crystal.
"This is a memory chain storage box, and inside it are the memory chains of Xiaochengzi and Xiaoyan." The voice was cold and ethereal.
But once again it was beyond everyone's expectations.
"mine?"
Bai Yan didn't expect that there was something about him in this.
"You don't remember anything before you were six years old, right?" Bai Qinghan just asked him.
It was true, but Bai Yan just thought that he had suffered some injuries in the black market and had forgotten about them.
And he remembered that Bai Qinghan had told him the same thing.
"The gene transfer experiment back then was only used on Cheng Yu. As for you following that Li family member back from the future to this time point, you were separated from him when you first came here and were sold to the black market by human traffickers."
Bai Qinghan searched for a year before he found him on the black market.
