In the afternoon, Xue Jing observed that "Twin Lifes" on the panel flashed back with a pale golden glow and conducted further experiments, from which he drew some conclusions.
"The usage time is about 20 seconds, and after it's fully used up, it takes about six hours to cool down to 20 seconds..."
"The cooldown recovery is ongoing at all times. Suppose I use one second of 'Twin Speed', leaving 19 seconds, one-twentieth of six hours is 18 minutes, meaning I will fully recover to 20 seconds of usage time after 18 minutes."
Xue Jing derived detailed usage data from his experiments.
Unfortunately, the usage time of level 1 Twin Lifes is just too short; he had to calculate his resources carefully.
"Speaking of which, practicing the Coiling Dragon Art is also an 'action' that can be accelerated with 'Twin Speed'."
"This could directly double the efficiency... but the current duration is still too short; I'll worry about it later."
