There was a brazier under their buttocks and a savage mentor waving a whip in front of them. All of them wanted to die.

Shen Yanxiao’s devilish training methods were completely inherited from Xiu. When Xiu was training her, some methods were even more brutal than this.

Now, Shen Yanxiao had finally gotten rid of her teacher and started to ravage these brats.

For the entire afternoon, the naughty brats had been in the horse stance. The promised one hour had directly become three hours! In between, they could only rest for five minutes every forty minutes, and then it was the inhumane horse stance…

God knew who had developed such a torturous thing.

The teenagers, who originally had the mentality of watching a strange mentor, now had a taste of living hell.

Three hours later, they finally got out of hell.

One by one, they fell to the ground. Their legs were so numb that it did not feel like they were their own.

They wanted to cry. If they had known that this mentor named Yan Di was so abnormal, they would not have come even if they were beaten to death. Even if they had to take sick leave, they would run as far as possible!

Compared to the pain of the naughty brats, Shen Yanxiao was also in pain.

She did not expect the physique of the undead to be so bad. They still had time to rest after three hours, but some of the undead teenagers already showed signs of physical exhaustion. If they could not withstand this amount of training, how could she continue with her training plan?

If those teenagers knew that today’s training was just an appetizer and that the real feast had yet to come, would they collectively slit their throats?

Just as Shen Yanxiao was wondering if she should change her plan tomorrow, Kehr came in from the entrance of the martial arts arena.

The group of abused teenagers almost wept with joy when they saw Kehr.

“How is it?” Kehr walked to Shen Yanxiao and asked casually.

This was his first attempt implementing physical skills into the courses of the academy. Previously, he did not appear in order not to disturb Shen Yanxiao’s teaching. He had calculated the time and came over quietly.

Kehr noticed that dozens of braziers were placed at one end of the martial arts arena. The oil in the braziers was almost exhausted, and only a small flame was still flickering in the wind.

Shen Yanxiao shrugged her shoulders. Although she wanted to say that the physique of these naughty brats was too poor, she was not sure if all the undead were like this, so she simply said nothing.

Seeing that Shen Yanxiao had nothing to say, Kehr turned to the students.

“How do you feel today?”

Kehr’s inquiry seemed to have opened the floodgates. The students who had been suffering all afternoon exploded at this moment.

“Mentor Kehr! Mentor Yan Di, she… she hit people!” An undead girl cried like a weeping beauty as she pointed at Shen Yanxiao. Her pair of slender legs trembled. Obviously, she had been squatting for too long.

“Hmm?” Kehr was slightly stunned.

“As soon as she came, she beat up Zhanye and Shile. She even punished us by making us squat on top of a brazier and whipping us!” The more the undead girl talked, the more aggrieved she felt. Bead-sized tears rolled down from her eyes. In Deathfire Academy, there were very few female undeads. Even when other mentors were teaching them, the female undeads would have a certain degree of preferential treatment. But today, not to mention preferential treatment, Shen Yanxiao had seen several times that the girl could not stand steadily and whipped her feet several times, almost hitting her body. She was so frightened that she almost fainted.
