章 971: Potential Location Of Gu Yao?

Lin Mu was truly angry upon hearing the use of the failed experiments. Not only were a lot of humans sacrificed to make the Rebirth blood, even then there was no guarantee and the these cultivation base boosting pills were made.

"Do the ones who take these pills know about it?" Lin Mu questioned.

"N-no… most don't. At least the ones that are not part of the Gu Legion directly don't know. We are not allowed to tell anyone this…~cough~" The man said as he coughed again.

Lin Mu's eyes narrowed as he sensed the further changes in the man's body. 

'Does he not sense them?' Lin Mu wondered.

His senses were fully alert and he would know if the man did anything. Even something as much as a flicker in the heartbeat would be felt by Lin Mu. Thus, he would know if the man ever lied.

But so far, he had been saying everything truthfully.

"How many pills can be made from one of the failed experiments?" Lin Mu questioned.
