"However, I can use other mental cultivation methods to form a pill fire!" This was Lin Yi's second time talking to boss Bai in private, and he could tell that boss Bai valued him a lot. Lin Yi didn't hide anything and told him that he knew other Arts!
Plus, Lin Yi didn't care that he knew that Yu Panhu was eavesdropping outside. He'd pretty much fallen out with a lot of hidden houses already, and the fact that Lin Yi was a refiner wasn't a protection for Lin Yi. He'd already done what he needed to do with Yu Panhu, and whether it was the competition or the cauldron, he'd made it worth it. Even if Yu Panhu found out that Lin Yi wasn't a refiner, he'd regret it and wouldn't be able to do anything to him.
"Oh? Using other mental cultivation methods and pithy formulas to condense the pill fire?" Boss Bai's hope was reignited after hearing Lin Yi's words."Show me your alchemy fire!"
