Yingbao: "Once I've finished opening the meridians for Nuannuan, Jiang Jie, and Jiang Wu, I'll make a trip to the Immortal Cultivation World."
Otherwise, they won't have enough spiritual power for cultivation, and opening their meridians would be for naught indeed.
Xuanwu: "Very well."
The master should indeed take a trip, for a fragment of the Divine Pupil is in possession of someone in that world. As long as it is retrieved, the master's strength can be restored to 99%.
A month flashes by.
The spiritual medicines in the Divine Mansion gradually mature. Yingbao left behind a batch of seeds, began harvesting the medicinal materials, then followed the prescription to prepare the body-forging, meridian-opening tonic.
Opening the meridians is extremely painful. It involves using spiritual power to clear all the spirit veins in one's body, allowing the spiritual energy to flow smoothly, and finally condensing one's spiritual root in the upper, middle and lower dantians.
