บท 3621: The realm of dragon blood (1)

However, it was not easy for a person who had made the great vow of the heart demon to kill the person who had defeated him. After making the great vow of the heart demon, there would be some connection between him and the person who had defeated him. This connection was not usually obvious, but if the person who made the vow wanted to kill the person who forced him to make the vow, the other party would sense it. It was because of this that very few people who had made the great vow of the heart demon could kill their own oath master and break their heart demon.

If one couldn't break their heart's demon, it meant that it would be very difficult for one's cultivation to improve. This made many people who had made the great heart demon oath very distressed. In the end, a cultivator finally created a method that could improve one's cultivation and even allow one to ascend. This method was the second method to improve one's cultivation after making the great heart demon oath.
