Nie Guangyi suffered from insomnia.
For a genius, this was an incredibly unbelievable thing.
A genius is someone who sleeps when they want to sleep, and wakes up when they want to wake up.
Those who think such a statement is made up might do well to seriously look into "Da Vinci Sleep."
The reason why Da Vinci was so capable had an inseparable relationship with his adherence to polyphasic sleep.
To be specific, it involved sleeping for 15 minutes every four hours.
After a week, one could save several dozen hours.
The length and quality of life were exponentially increased under the augmentation of this sleep method.
Who said time is fair to everyone?
In his diary, Da Vinci wrote down this wonderful invention.
As for whether he achieved it, that's another unverifiable mystery now.
Unless Meng Xin Zhi once again dreams of Brother Leo.
Say what you will, but Nie Guangyi, despite his age, was tasting the flavor of unexplained insomnia for the first time.
