Even though there weren't many people, they couldn't invite outsiders to live here. After discussing with Mr. Thompson, Dong Tianyu wasn't planning on informing any relatives who did not arrive about their situation.
Some may call it ruthless, but it was a situation left with no choice. As different natural disasters kept striking, if Mr. and Mrs. Thompson were still unwilling to move into the refuge center Dong Tianyu had built, he would have to provide more and more supplies to them.
No matter how much he said, whether they were blood-related or they owed him the favor of birth, Dong Tianyu, having abundant resources, would not allow his parents to live their previous life of low living standard despite not having to worry about food and drink.
Ultimately, Dong Tianyu was too indulgent towards his parents. If he was cruel-hearted, he could disregard their wishes and forcibly move them into the refuge center.
