After learning the Spirit Skill·Candlewick Trace, Du Yu conducted a thorough experiment.
It proved that as long as the candle flame burns, no matter how far Du Yu goes, he can receive messages transmitted by the other party.
Even in the Otherworld!
Even when Du Yu enters the Sea Realm, he can feel it when Xiaoyan extinguishes the flame in the Red Bamboo Courtyard.
It's truly like a temporary contract has been signed between a person and a flame.
After all, when Du Yu and his Demon Pet are inside and outside the Mountain and Sea Bell, they can still communicate through the contract.
Purely from the perspective of "transmitting information," this Fire Spirit Skill is incredibly powerful!
Although the transmitted information is very vague, Du Yu only knows there are living beings passing by and can't figure out exactly what they are.
But bear in mind, this is merely the Second Level·Unyielding Silver Quality Candlewick Trace!
