Deathfire Academy belonged to the third type, which was open to both kinds of undeads.
However, the conditions for resurrected undeads to enroll in the academy were very harsh. Not only did they need to undergo a death energy test, but they also needed the recommendation of the high-level undead who resurrected them.
Moreover, schools that specialized in dealing with resurrected undead taught very strange content. Most of the content they taught was how to make resurrected undeads submit to purebred undeads.
Shen Yanxiao had also thought about whether she should go to an undead academy or not. After all, a lot of the knowledge there was tailor-made for undeads. Going to such an academy would be much faster than her working behind closed doors. However, because the enrollment conditions were very harsh, Shen Yanxiao could only give up.
After all, she did not have anyone who could recommend her.
