Chapter 221: Famous Across the Country

"That many already? How much money was spent on promotions?"

Upon hearing the news, Li Zhongnan was shocked. There were only five to six billion smartphone users in the country, while the downloading rate of Nan Xue Intelligence had already exceeded one billion within ten days of its launch—a terrifying speed.

Guan Yazhi smiled and said, "Not a single penny was spent!"

Li Zhongnan gasped in surprise, asking, "How did you manage that?"

Guan Yazhi gave a faint smile, "It's simple. We entered into strategic partnerships with several major internet companies, who promoted our product for free."

Li Zhongnan inquired further, "What can we offer them in return?"

Guan Yazhi responded, "The first is traffic, the other is resource exchange. After Nan Xue Intelligence gets enough installations, we can consider prioritizing a series of other collaborations with them."

Li Zhongnan chuckled, saying, "I don't understand all this. You just handle it."
