Han Du looked at Tu Xinjian a little speechlessly, as an adult or a professor, his reaction was really a bit out of character, of course, maybe he just couldn't help it, it wouldn't be like this under normal circumstances.

"Professor Tu, what's wrong with you?" Han Du pretended to be puzzled and asked.

"Hah...... Ha ha...... It's okay, your parents are my old classmates, and I was not mentally prepared for a while when I suddenly heard that they were missing. Tu Xinjian tightened the thermos cup in his hand, and looked at Han Du again, there was a hint of complexity, he had long felt that exploration was a dangerous undertaking, Han Du's mother followed Han Song to go south and north, he didn't support it from the beginning.

The reason why he has such an idea is that he participated in an expedition with Han Du's parents back then, and since then he has had a psychological shadow on the expedition.

"Professor Tu, I'm here to find you today, and I want to ask you about something unspeakable, I don't know if you want to hear it." Han Du still cut to the chase.

Tu Xinjian: "Say." ”

"That's right, I want to know how my parents decided on a relationship back then, can you tell me?"

Han Du's words were also a bombshell, Tu Xinjian was slowly drinking the water in the thermos cup at the time, and it was all squirting out at the moment.

He looked at Han Du in a daze, wondering if this kid was missing the root scripture and couldn't speak with his brain?

"Professor Tu, I know it's inappropriate for me to say this, but it's been so long since you and my parents happened, you should be able to let go, I have to know how they determined their relationship back then, as for the reason, I can't say, please forgive me."

Tu Jianxin didn't intend to investigate the reason, for him, this was an unbearable past, who wanted to know the reason, and he couldn't answer

"I'm sorry, I really don't know, your parents publicly said that they were together when they were pregnant with you, and they were covered tightly before that." Tu Xinjian smiled wryly.

Han Du was also very surprised, does this mean that Tu Xinjian has been licking the dog for a long time in the middle? Of course, there may be other hidden secrets that Han Du can't know.

Han Du should be more concerned about Tu Xinjian's ignorance of the events of the year, his attention returned to this, and he asked with a serious face: "Can't you provide any clues?" ”

Tu Xinjian sighed in an old voice, hugged the thermos cup and said: "Actually, I was with them every day, and I can probably still feel some abnormalities, if I guess correctly, it should be during that expedition to the Black Gold Desert to confirm the relationship, at that time, there was a sour smell of love that was discovered by me and several other team members and professors, but they themselves did not admit it and did not announce it, and we are not good at getting to the bottom of it." ”

Han Du immediately understood that he could only go to Heijinsha Mi to find clues, but after so many years, could he still find clues there for his parents to confirm their love relationship? However, in any case, he must go to the Black Gold Desert, follow the route his parents walked back then, and maybe find something.

"Professor Tu, do you remember your route in the Black Gold Desert? I'm going to go there again. Han Du asked sincerely, worried that Tu Xinjian would not cooperate.

The professor really looked at Han Du with strange eyes: "You kid, the Black Gold Desert is very dangerous, just run around and be careful that your life is not guaranteed." ”

Han Du: "......"
