The next morning, Tang Yue and Tomcat informed Mai Dong of the news, moments after she woke up.

"Tianzhou… 37?" Mai Dong was surprised. "It's still alive?"

"Tianzhou 37 was launched before Earth disappeared, but for some reason, this spacecraft escaped the misfortune of vaporizing with Earth. Furthermore, it very accurately found its destination. It will arrive on Mars twenty days' time, according to plan."

"I recall that Tianzhou 37 is a cargo spacecraft."

"Yes." Tang Yue had spent hours to calm his excitement to make himself look composed, but he still wasn't able to repress the joy in his eyes. "Just on food alone, that spacecraft has five tonnes worth. There's fruit, vegetables, beef, fish, and even Australian lobster canned food!"

He handed the inventory list to Mai Dong.

Mai Dong began scanning through it.
