Lin Yuan was worried, but Xiao Linzi was after all a boy, and a very smart one at that, so she thought it unlikely he would run into trouble.
The only issue was with the children at the tofu shop. They were all little beggars in the past and it was because of Xiao Linzi that they came to work at the tofu shop. Now that Xiao Linzi had left, and these kids had a deep connection with him, even seeing him as their leader, she didn't know if they would still want to stay without Xiao Linzi around.
Lin Yuan went out of her way to ask a few of the children and, surprisingly, not a single one wanted to leave. They said Xiao Linzi, though gone, would definitely be worried about his brothers in hardship and would surely come back to check on them. They wouldn't leave so that Xiao Linzi would have a place to find them when he returned.
