There were quite a few people in line; it took half an hour before it was Li Feng's turn.

"Could you please help me look up Li Changlin? Li is the 'Li' in 'dawn,' 'Chang' in 'long,' and 'Lin' in 'forest.'"

"What is your relationship with the person you're investigating?"

To prevent malicious inquiries, anyone looking for someone at the S City base must present their identification and register.

ID card, household registration book, passport, even marriage certificate or student ID are all acceptable, as long as they can prove your identity.

If you really don't have these, there's a missing person notice board outside where you can post missing person ads.

"It's my dad."

Li Fenggang, who was behind him, also saw the process clearly. He immediately took out his ID card and handed it over to the person to show.

The other party glanced at it before nodding and continuing the search.

"How old is he? What is his ID address?"

Li Feng leaned against the window, his palms sweating nervously.

"Fifty-two years old, from Tianxi Town, Wutong County, S City."

The other person typed rapidly on the keyboard, entered a search term on the computer, and finally shook their head.

"The base has no record of this person checking in."

Li Feng's eyes were filled with panic, and he hurriedly gave out his mother's name and his sister's name, but the result was still the same.

He felt disappointed again and began to feel uneasy. If they didn't even have a base in S City, where would they go?

He dared not think about it anymore.

The staff member was also very responsible; based on the search address, he found other people who had registered at this location.

"There are some people at the base in Tianxi Town, the place you mentioned. You can take a look and see if there are any acquaintances you know."

As he spoke, he turned the computer screen so that Li Feng could see it.

"Let me see." Li Feng carefully looked at each name one by one, afraid of missing anything.

Suddenly, he pointed to several names linked together.

"This, this, Li Guosheng, is he an elderly man in his seventies? If so, then I know him."

The staff only showed him a list of names; he had to click on it to see the detailed information.

He turned the computer screen back, checked Li Guosheng's information, and nodded.

"He's 78 years old. He should be someone you know. Do you want to go and ask him about it? He lives at the base."

Li Feng was unwilling to give up on even the slightest clue. "Yes, yes, please tell me his address, thank you!"

Li Feng got Li Guosheng's address. He had been out for quite a while and was worried that Li Yiyuan and the others would be concerned, so he decided to go back first to let them know he was safe before going out to look for them again.
