Lin Yi could only send his Qi into other people's bodies by using needles, he couldn't do it with his hands.
It seemed that he should let the pig and the purple lightning Beast talk to each other and see how this guy did it. It'd be amazing if Lin Yi could learn it-he'd be invincible if he just injected some pure Qi into his opponent.
But Lin Yi didn't think much of it-were all the practitioners with contracted spirit beasts stupid? Did they not think of this? It didn't seem like it could be done at all.
Shaking his head, Lin Yi started to help Zhihai refine the purple lightning beast's Qi, but only the beast's Qi could be so easily absorbed by Lin Yi. If it was someone else's Qi, Lin Yi wouldn't be able to do it so easily!
Lin Yi could absorb this type of Qi for his own use, but he couldn't do the same for others like fire poison Qi. He had to force it out of his body by wrapping it with Qi, which was more troublesome.
