Pi Pa is the 2nd most powerful spirit beast on the FaRam. Am I wrong?

We know that individuals can gain Qi through eating food. This is how Bi De first gained Qi, along with Pi Pa and Chun Ki. We know that even a "vegetarian" can gain Qi from meat containing Qi because Miantao insists that Yin eat every bit of Qi laden food they come across. This gives her digestive issues while refining that Qi.

Pi Pa consumed Sun Ken and at least 2 other cultivators when the might of Fa Ram instructed the Whirling Demon Gang. She was still refining the Qi a week later when Jin gave her some of Meiling's stomach medicine. Now some may say that demonic Qi is not compatible for the cultivation of a member of Fa Ram but demonic Qi can be used. One of Shen Yu's complaints about being called away to the war was that the demons he was fighting were too weak to be refined into a pill.

So what I'm saying is that Pi Pa has consumed a lot of Qi. She rarely leaves the FaRam so is always eating Qi rich food and eating the cultivators was a whole lot more Qi. Wa Shi isn't really a spirit beast but could be argued that he is stronger than Pi Pa because you know... dragon. And perhaps Tigu on account of all the training she does could be rated 2nd. However, I am still convinced it is Pi Pa and we just haven't seen her unleash her full might.
