16th of July, The Day Finally Arrives

If Zhang Heng remembered correctly, Apple's Bluetooth Wireless AirPods were released in 2016.

The Apollo quest was set in 1969. Seven years later, Steve Jobs, Steve Wozniak, and Ronald Wayne founded Apple Computer together. As for Bluetooth technology, it was created in 1994 by the famous telecommunications company, Ericsson. In other words, these AirPods were definitely not a product from this era. So, who in the world was the man calling himself Einstein?

Einstein didn't come to see Zhang Heng because life in Area 51 was boring. He had his own agenda when he came to meet the astronauts preparing to set off for the moon. Other than Zhang Heng, he didn't look for Jia Lai and Bruno. Zhang Heng didn't even know if he was really one of the engineers in Area 51, let alone figuring out why he gave him the headset that way ahead of this time.
