[LV5 Spiritual Energy Mine Fusion successful, Nine-Snake Mother Tree acquired Skill LV1 Engraving Seal, acquired Skill Advancement LV5 Crystal Mine Fruit]
The breakthrough information of the Nine-Snake Mother Tree was conveyed to Su Han through the Book of Blood Spirit, the resulting aura providing him with a warm flow of spiritual energy that increased his strength slightly.
It had been seven or eight days since he left Huiyuan City and South City; by his reckoning, the time should be just right for the fusion of thousands of spiritual energy mines to be completed.
"Still no breakthrough?"
Su Han slightly furrowed his brow. Without a breakthrough, he would have to continue with the fusion. Fortunately, there was still a substantial number of Lamp Tree crystals to be fused, and they were in greater abundance than the spiritual energy mines.
