The Yingke Platform's live stream software can only normally call the phone's built-in camera. Achieving high-definition bobber viewing without any modifications is impossible.
But who is Zhang Yang? He has a trick!
Before starting the stream, Zhang Yang specifically bought an external zoom lens online, which can be attached to the phone's camera with a mount. This way, he can achieve high-definition viewing of the bobber.
The zoom magnification of the external lens is 18 times. Even with the current 7.2-meter long rod, the bobber on the water's surface is still clearly visible.
The only minor downside is the slow speed of focusing on the target, requiring patience to adjust it bit by bit. Then the live streaming stand is fixed, and Zhang Yang can handle minor adjustments, as the bobber's drop point doesn't vary much each time!
Zhang Yang swiftly took out the lens and mount from the toolkit and began the live installation and adjustment in front of the stream viewers.
