Hearing this question, Fan Yuantang stood up, extended his right hand and patted Qian Cangyi's head, saying:
"Liang Ping, it's not certain, as long as the external environment doesn't change from now, the box can continue to exist. However, you're not wrong either, because the external environment will change anyway, it's just a matter of time."
Having said this, he glanced at the light gray standing clock on the table. The hour hand was approaching the number 10, and in another 5 minutes, it would be 22:00.
"Go to sleep now, it's getting late, homework can wait until tomorrow. Children need to rest properly; staying up late to study isn't good for your health."
As he spoke, it seemed he remembered something, reached his right hand into his trouser pocket, took out his wallet, and then pulled out a red banknote and handed it to Qian Cangyi.
"Take this, buy whatever you want with it, and if it's not enough, ask your grandfather for more."
