Gu Chengbai really didn't want to admit this.

But that's the reality.

He sighed and said, "That's right. So later we started paying attention to the movements of the Huo family. After the incident at Pier 9, we rushed there as soon as possible."

Bo Yuting said with a half-smile: "The Huo family is doing something right under your noses, but you didn't notice it. You are really amazing."

Gu Chengbai retorted, "Who said there wasn't any? At least two years ago, we had already found out about the Huo family, but we didn't know who they were at the time. And because of our interest in the underground city, we quickly discovered the artifacts that appeared in the capital, and determined that it might be related to the underground city. We also rushed over at the time, but..."

Bo Yuting continued, "It's just that what you got was a fake, and the Huo family set you up and made it public, so they know that it was you who had been against them all along."

Gu Chengbai's mouth twitched slightly when he heard the sarcastic tone, and he really didn't want to pay any attention to Bo Yuting.

Gu Chengbai saw Lin Wu frowning from the corner of his eye. He was afraid of leaving a bad impression on her, so he quickly explained: "We are not completely led by them! Earlier, after I checked the whereabouts of the Huo family in the north city, I followed the clues and found that they were in Lingnan. The clues there seem to be related to the underground city. I have sent people to investigate!"

Bo Yuting asked, "Is there any progress?"

Gu Chengbai: “………Not yet.”

Bo Yuting: “Oh~~”

Gu Chengbai: “…”

Gu Chengbai said with a dark face: "Because there is a natural barrier in Dayuling Mountain, it is difficult for outsiders to get in and out smoothly! Even the Huo family has wasted a long time there. How can I make any progress in such a short time? Can my people grow wings and fly in?!"

Bo Yuting: “Tsk.”

Gu Chengbai: “…”

After hearing this, Lin Wu said, "I don't care about these for now. What I want to know is another question."

Gu Chengbai hurriedly said, "You tell me."

"Teacher, what's going on?" Lin Wu asked, "You said you learned about the underground city from her, and it was because of her insistence that you kept investigating. But after all you said, what you investigated had nothing to do with her. Why didn't you just ask her what the underground city was?"

This is also a rather strange point about Bo Yuting.

He said, "Yes, I have been investigating for many years because I have no clues and am completely confused. You have such a good information channel as my aunt, so why are you still making slow progress?"

Speaking of this, Gu Chengbai smiled bitterly, looked at Lin Wu, and asked, "Wuwu, when you were in contact with Mom before, did you find anything wrong with her?"

Lin Wu said: "Although the teacher accepted me as a student, she has not yet started to lead me in project research. She just gave me one and asked me to cooperate with other students she taught. A lot of things happened later. If you count carefully, I didn't have much contact with her."

She was puzzled: "I don't know what you mean by wrong."

Gu Chengbai pursed his lips slightly and raised his finger to point at his head.

Lin Wu was even more confused.

Gu Chengbai lowered his voice, "Back then, Mom encountered danger and had a difficult delivery in North City. She almost died in the operating room with you. Later, Mom finally gave birth to you, but the doctor told her that it was...'stillbirth'. She couldn't accept it and was greatly shocked. She was in a trance and disorder for more than half a year after giving birth."

"Dad said that Mom had nightmares every day. When she woke up, she would tell him those things over and over again. She didn't believe that you were gone. When she was severely depressed, she even thought about committing suicide. Later, Dad had no choice but to take Mom abroad for treatment. He found a professional to hypnotize Mom to forget those things. Mom gradually got better."

"Then she rested for another two years before she recovered like a normal person. At that time, Mom asked Dad if he remembered that she was pregnant and where the child was. After discussing with us, Dad told Mom that she went on a business trip to the North City and met the Gu family's rivals, and lost the child in a difficult labor."

Lin Wu was stunned.

This brought Lin Wu back to his senses. After a moment of silence, he asked, "What happened next?"

Gu Chengbai said, "Later, we tried to ask Mom about the underground city, but she had indeed forgotten everything. We were afraid that it would upset Mom and make her go back to her old ways, so we never told her about it again. So we never told Mom about what we investigated, and she didn't know what we were doing."

Lin Wu was a little confused. "If that's the case, why did you continue investigating? Maybe what the teacher said was false. Since she... you don't have to..."

"What if what mom said is true?" Gu Chengbai looked at Lin Wu gently, "What if what mom said is true, and you are not dead, but just kidnapped... For things like this, it is better to believe it than not. Besides, we have to avenge Uncle Tangfeng."

Lin Wu stared at Gu Chengbai blankly, wanting to say something, but when he opened his mouth he didn't know what to say.

Bo Yuting held her hand tightly and said, "If that's the case, forget it. Don't worry, we won't say anything to Madam Chi that would irritate her."

Gu Chengbai hummed softly.

"Oh, there's one more thing," Lin Wuxiang finally found his voice and spoke in a hoarse voice, "Does she...does the teacher have any tattoos?"

Gu Chengbai was stunned: "Tattoo?"

Lin Wu nodded, "Similar to the phoenix, the tattoo will not appear normally, but will appear when the body temperature rises."

Gu Chengbai said in surprise: "No. We have lived with Mom for so many years, and we have never seen her have any tattoos."

Lin Wu asked: "Then you don't have any either?"

Gu Chengbai shook his head: "None."

Lin Wu hesitated and said, "I heard that you have a younger sister, she...she doesn't have it either?" Perhaps this kind of tattoo is passed down to females but not males, so if it appears on the younger generation, it will not appear on the previous generation?

"Are you talking about your sister Si Yin?" Gu Chengbai quickly responded.

Lin Wu said nothing.

Gu Chengbai was not disappointed and said, "Your sister doesn't have any tattoos. Why do you suddenly ask this? Do you have any tattoos on your body?"

Lin Wu hesitated.

Since she was sure it was not a tattoo she was born with, she was a little hesitant about whether to tell Gu Chengbai.

Bo Yuting looked at Lin Wu and didn't urge her. He just said, "If you don't want to talk about the rest, forget it. Shall we go eat?"

Lin Wu was silent for a moment, but finally said, "Yes, I have such a tattoo on my body."

Since Chi Yangzhi is related to the underground city, and the Gu family has been investigating the underground city, it is nothing for her to tell them about her tattoo related to the underground city. Maybe they can help her find unexpected gains.

Gu Chengbo asked in confusion: "Why do you have this tattoo? And you even asked mom about it..."

He thought of something and his expression changed slightly: "Could this tattoo be related to the dungeon?!"

Lin Wu nodded and briefly told him what he had learned from the two survivors of that team.

This amount of information was so huge that it took Gu Chengbai several minutes to digest it all. He was stunned and asked, "So this tattoo is the key to finding and entering the underground city, and it's also what the Huo family has been looking for all these years?"
