King of Constructs

Construct is the greatest discovery of the Federation. It contains geometry, mathematics, materials science, etc. It is knowledge and power. Xie Hui, whose knowledge of the new century was only a game trailer, traveled to the Federation and couldn't help but look up to the sky and sigh: "Where is my golden finger?" But no. Our ancestors told us that we can make enough food and clothing by ourselves. Xie Hui decided to grab a golden finger back.
