The Yangtze River Delta City group.
A huge building that was made of steel was located on the edge of the coastline of Shanghai's neighboring port area.
The dark gray steel frames constituted the outer wall of the building. The beautiful outline looked like a cradle from a distance, gestating the fire of life and hope.
Its name was the Heart of Asia.
Every inch of steel on its body was a type of special steel produced under the low gravity and low-pressure environment of Mars.
In order to commemorate the population of Tiangong City that broke through the 10,000 mark and the gross production value exceeding the threshold of one billion, China used steel sent from Tiangong City to cast this landmark building.
And it was this building that directly doubled the GDP of the Martian colony the following year.
