Chapter 467: Breath of the World Tree

As Shion's confusion grew she said nothing and simply continued to watch. Since she couldn't understand why such a skillful alchemist would create a long-lost potion that wasn't relevant to the situation Shion decided to keep quiet and look at what would happen next.

After she was done mixing the potion Lara looked a bit disappointed, the quality of the potion was barely acceptable. Still, she had no choice since the materials on hand were less than desirable, she was even forced to use her own blood as a replacement material to create this poor-quality potion. 

In one of Lara's past incarnations, Evangeline was a genius alchemist, who later became the greatest of alchemists. She was one of the few mortals that could challenge Old Gods and actually win. She was considered by most of the ancient alchemists as the pinnacle.
