i think they miss a part? WX suppose to consume a pill given by XG..
This series is more accurate to the books than the previous were. In episode 7 you can see Wu Xie swallow a piece of metal, or at least he thinks it's piece of metal. It was during the fight with Pang Zi during hallucination, so he wasn't sure if it was real. In the book it was piece of corpse's belt, he thought he swallowed metallic piece of the belt, he doesn't find out until much later it was the "pill". In the series you're referring to, Xiao Ge takes the pill out of the belt and feeds it to Wu Xie directly, because they were going more into the bromance theme.
