A level 35 Phantom Demon not only gave him powerful Star Power, but also increased his spirit power by 82 Hertz!
As expected...
Contracting with soul-type Guardian Beasts with powerful spirit powers is indeed a good way to enhance one's spirit power!
Previously, he had consumed 6.85 million system energy to increase his spirit power by 324 Hertz.
Unless there is a large surplus of system energy, it would be better to find ways to help the Phantom Demon level up more.
Increasing one Combat Power Level and one Species Level would probably raise his spirit power by over 160 Hertz!
"Xiaofan?"
The Lame Grandfather waved his palm in front of Chen Fan: "Are you alright?"
"How did you contract that Phantom Demon?"
"That's too risky!"
Chen Fan came back to his senses, smiled and said: "Fortunately, Lame Grandfather helped me suppress the malicious thoughts... I'm fine now."
