Kapitel 2222: Until Death Do Us Part

After a while, Ye Jian asked in confusion, "Why haven't there been any letters for four years?"

"That's because our country conducts research on missiles and satellites in secret. In order to keep it a secret, all the scientists involved in the research are not allowed to leave the research base easily, let alone contact their families casually. They live in isolation," Xia Jinyuan replied Ye Jian with a respectful tone for these researchers. "It's normal to not receive or send out any letters for four years."

Ye Jian was in awe.

Li Jinnian knew that Xia Jinyuan was speaking up for him. He nodded slightly to express his gratitude. "Grandfather and Grandmother are both in research and development. They rarely come home. They don't know anything about my mother and uncle. It's normal for the two of them not to receive any letters from their children in a year.
