Just as Bai Zhenzhen was fiercely battling with numerous Qi Refinement masters, Zhang Yu also planted the Heavenly Spirit Root into his Dantian, initiating the fusion between the Spirit Root and his physical body.
What Zhang Yu chose this time for his Foundation Establishment was the Qi Sea Spirit Root.
Fu Ji said, "Different Spirit Roots have very different effects after Foundation Establishment."
"Using a combat Spirit Root for Foundation Establishment enhances combat power more rapidly, but in the long run, it's not as promising as cultivating a Spirit Root."
"However, once you complete Foundation Establishment, you'll need to fight, so some pure cultivation Spirit Roots aren't very suitable for your current situation."
"Thinking it over, the Qi Sea Spirit Root is most suitable for you."
Zhang Yu agreed with Fu Ji's suggestion.
