What Zhao Hai didn't know was that the power Lei gang was using was actually a type of technique called mind-reading, a Buddhist technique. This was related to Lei gang's cultivation technique. Although Lei gang's cultivation technique was mainly based on the bloody massacre sect's cultivation technique, many of his cultivation techniques were derived from Buddhist techniques. Therefore, he had really managed to learn this mind-reading technique.
However, this technique was not as magical as the legends said. It could sense a person's thoughts, but this feeling was very vague. If a person was on guard, this mind-connected technique would be of no use at all. Lei gang had used this mind-connected technique to look at Zhao Hai's Dharma power and see what it was.
