"Using this machine, you can travel through time and space?"
"No."
"???"
"But you can rely on the power of nature to carve a gap in the river of time when the Temporal Tide causes ripples."
Shen Qingxi explained to Li Mumu, "You know the concept of a gravitational slingshot, right? Artificial spacecraft use fuel to boost in space, but the speed doesn't increase significantly. However, if the gravity of a planet itself is used like a slingshot, you can accelerate and catapult yourself."
"The working principle of this Gonggong Engine is quite similar to that."
"Are you sure this thing can actually be used?"
"Not quite sure."
"So you want me to be the guinea pig?"
"No, the first time has to be myself. Only I can understand the depth of the machine I created."
Shen Qingxi pointed to the operating platform next to them, "I'll give you three days to read, memorize, and understand the operation manual I wrote. In three days, we begin the first cross-time experiment."
