His condition worsened

The door to white lotus chamber was swang opened before someone came in with their wobbly legs. Right after the youth closed the door back, he collapsed, his wobbly legs giving away on their own. 

At least, Wang Li Jie managed to finish his meal without his own condition getting noticed by the immortal and mistress Wang. But if it was just the throbbing pain of his core like before, the youth wouldn't end up collapsing like this. It was because there's another problem came up with his weak body on the way back to his chamber.

 At a certain place on his way while Wang Li Jie was walking back to his chamber, enduring the throbbing pain of his core, his chest tightened all of a sudden before a chilly sensation started to spread through his whole body.
