Chapter 338: The Arrival of the Dark Legion (6th Update)

Ada was still calm and calculating: "I understand now, it seems that the energy of the Dark Heart is too powerful, but for the current Su Yu, it exceeds his bodily limits, the side effects are pretty severe. Prolonged use is extremely dangerous."

In order to fully awaken the Dark Heart, Ada had used up a large volume of her blood. She seemed lethargic at this moment, but she was very excited because she knew that although Su Yu was in extreme pain, writhing on the ground, his life was not in danger.

True enough, after screaming in agony for a couple of minutes, Su Yu's voice gradually faded. He then stretched out all his limbs and lay sprawled out on the ground, fully laden with sweat and pale. His experiences these few minutes were nothing short of a nightmare from hell. Even for someone as composed as him, the pain forced him to squirm on the ground. One could only imagine the intensity of his suffering.
