Survival Game: Call Me an Honest Businessman

[Leveling up + No romantic pairing + Thrilling read]
All of humanity is drawn into a survival game, and Li Zhi changes his profession ahead of schedule to become a "merchant".
Starting from a stall in the most primitive orc market, he gradually grew into a well-known cosmic merchant.
Other races: "What a cunning businesswoman! A cunning businesswoman like no other in a century! Not only is she shrewd, but she's also incredibly skilled in combat! Who would dare refuse to do business with her?!"
"Slander! Utter slander! I have always adhered to the principles of honesty and integrity in business, treating customers with sincerity!"
"Including robbing the Beast Alliance, the Qilin Clan, and the Mountain Giants?"
"How can a businessman's actions be considered robbery?"

Li Zhijue's awakened talent "D Card".
D card: Press the D key on your keyboard to refresh and generate five cards.
Copy cards, resource cards, blueprints, one-time talent items, equipment... Li Zhi's Origin Card?
Origin Card: The core of power's origin, its use can enhance strength and break through bottlenecks.
— Three identical cards can be combined to upgrade the card.
Li Zhi: They can become stronger by training at home and fighting in the training grounds, unlike me. I worked hard to get cards and finally managed to get myself to a three-star, five-cost, oh no, SSS-level human. It was all thanks to my own efforts!

The centennial rating is approaching.
The victor is king, the loser is slave.
Humanity is now being drawn into the rating system.
All races were indifferent; with only a dilapidated, leaky floating wooden house, humanity was destined to be nothing more than a resource, cannon fodder, and slaves.
Until one person transformed the floating wooden house into Noah's Ark.
All races: Impossible! How could humans obtain such high-quality materials?!
Li Zhi: If the quality isn't enough, I'll make up for it with synthesis. My deck has no limit!
