Lin Huang got himself a chair and sat on guard outside of Lin Xin's room. He used his Divine Telekinesis to penetrate the wall and was aware of Lin Xin's condition at all times although he was just a wall away from her.
Lin Xin sat by her bed with Life Crystals piled into a little hill under her bed.
She opened her mouth and the Life Crystals the size of a thumb turned into white rays which seeped into her mouth one after another. The pile of Life Crystals that looked like a little hill was getting smaller and smaller at a speed could be seen with the naked eye.
Whenever the Life Crystals pile on the floor finished, she would fill them up from the stock in her Emperor's Heart Ring immediately.
She repeated that for more than ten hours and eventually stopped when it was almost midnight.
