After eating and drinking to their hearts' content, Du Yue put away all the cutlery and rubbish and then looked at He Xing again. He Xing knew what Du Yue was going to ask. "The fourth base is going to start building an underground city. The government has recruited a lot of people to expand the base in the empty area."
The dust produced by the volcanic eruption drifted everywhere. It was unknown how long it would take for it to completely dissipate. The surface was no longer suitable for human life, so they could only expand underground. Building an underground city was the top priority now.
Although Du Yue understood the intention of the base, she also knew that digging out the underground city with bare hands would be a huge project. Du Yue did not think like this because of the base. She just did not want He Xing to move bricks and dig soil every day.
