Lord Of The Nation: Sign-in Discount Artifact At The Beginning

All the people came to the Chaos Continent, became the lords of one party, and participated in the struggle for hegemony among all races.
Fire is the authority of human lords. By signing in to Fire every day, you can obtain population, blueprints, food and other materials.
Huang Yu signed in on the first day and received a discounted artifact.
A batch of discounted products will be refreshed every day for Huang Yu to purchase.
So...
"This legendary weapon only costs 10,000 magic crystals after a discount? Buy it!"
"0.50% off dragon eggs? Give me a hundred!"
"0.0...01% off the extraordinary arms training camp! Is there such a good thing? Come to the bowl!"
...
Since then, Huang Yu and his territory have become famous in Chaos Continent!
