Training Instructor from Hell

Because of the super-concentrated bread that Xin made, Rias and her peerages training become easier for them.

They don't need to be tired because they are already full or precisely overflowing with energy.

Because of this, Xin adjusts the training field and adjusts the time inside of that dome. They can train inside for 24 hours while the time outside is only half of the day.

Every day Xin remodels their training program, for example, Rias and Akeno who already upgrade and learn mental training and systematic thinking.

Xin upgraded their training again, he made them battle a Demonic Beast that he finds not far from the Gremory Territory.

It's a Peak Middle-Rank Beast, it is much higher than Akeno and Rias rank but they are still safe because the beast doesn't know how to fly.

But the problem is Xin takes a beast with tough skin, they can't just defeat if they don't think of a good strategy to deal with it.

Next are Kiba and Xenovia, Xin teaches them 'Zanjutsu' or 'Art of the Sword' even Xin doesn't have any experience in this kind of Art, he still has some knowledge in it.

His task for them is to cut a huge boulder using only a minimal force without using their whole strength.

Xin called this 'Will Training' just like what Garp did last time they fought, to imbed their own will into a single move and that is to cut vertical, horizontal or any simple cutting technique.

He even shows them but Xin is different, he uses his palm to break the boulder without any effort and strength, well he really breaks the into dust but what behind the boulder is affected because he can still control it.

He also adds 1000 sword slash training for them if they fail every time they boulder.

Xin then takes Gasper, Gasper training is simple because he knew that Gasper will never go out from the box he is currently hiding, Xin gives him a simple mission and that is to stop the paper crane that he made.

He made a deal with Gasper: he wanted him to stop at least 20 pieces of Paper Crane in the mid-air. If not , he would take him outside without that box he is currently hiding and train with others.

Gasper accepted his offer, he knew that this training is for his own good, but he failed in the very first try so Xin took him outside while he was crying, he let him stop a special paper crane that was flying around him.

This time he made it harder, he needed to stop any crane that would attack him and dodge it before he got hit.

And if he successfully stops and dodge the paper crane 10 times he will give him special blood, blood from the strange flower 'Blood Rose' that can process to a special juice that can be used as a blood replacement for anyone.

He first let's Gasper taste it and just like what he expects Gasper instant like, he even starts to bother Xin to give him some before he starts the training but he stops. He only makes a deal for 10 times successfully dodge for 1 glass of that juice.

Well of course there's a consequence if he is hit 5 times, Xin will take the large glasses that he gave to him and then if he fails again he will take one item from him until he gets naked.

Gasper who's terrified fleas but Xin already imprisons him to a large transparent box so that he can't escape.

He forced him to train of course the deal is still up, he will get something if he successfully finished the task but there some punishment if he fail

Next one is Koneko, this cat is hard to train, she don't trust her own power, she usually relies on her own strength, if not Xin give her bunch of benefits like sleeping together or combing her hair she will never train her 'Senjutsu', 'Youjutsu' and 'Touki'.

Koneko training is simple, Xin only lets him meditate while constantly using 'Touki'. 'Senjutsu', and 'Youjutsu' are still hard for him and Xin needs Koroka to teach her because she already mastered using them.

Koneko said that her Bigsis already told her how to use 'Youjutsu' but she doesn't like training it because of the side effects of it.

Xin wants to ask what kind of side effect she is talking about but she only remains silent while blushing.

Well, in the end, she gives him a special dry fish and goes to Asia and Ravel for their next training.

Asia training is simple, Xin teaches her a new technique because she already mastered making Stamina Ball and healing Ball faster.

It's called 'Healing Blast' and just like its name it's an AOE ( Area of Effect) healing ability.

She only needs to store enough healing energy inside of her and let it explode inside of her surrounding.

Storing the healing energy is simple but Xin adds another level of difficulty for her, he asks for her to store faster and release is faster, meaning Xin wants him to store healing energy in 1 to 2 seconds and explode it fast then continue.

Xin makes a cheat-like healing ability that can spam all the time until the user's energy is depleted.

As for Ravel, Xin did not give her any kind of training, Xin actually wanted to see if he could transform or evolve Ravel Phoenix Power using the Solar Energy Ball that he let her absorb.

For Melan's assignment is to find Issei and lunch sneak attack him from time to time of course if possible give the new version of red bracer to him.

And day continues like hell to Rias and others while Xin becomes a hell instructor for them, but Xin's happy day suddenly starts to get messy.

First is Grayfia wants him to go back to the Clan, after all Staying to another Clan is inappropriate much for a Leader like him who did not have any special thing to do in Gremory Clan than torturing the other.

And the second is Sitri Clan is currently finding him because of what he did to Sona, they did not tell what happened to Sona but they only said that he needed to visit their Clan for some unknown reason.

The third is the Phenex Clan want to take their little princess back, this request is simple but the problem is Ravel doesn't want to go back even Xin is already pushing him out.

Ravel only said that she will go back if his Brother wins against Xin, and she fully understands that things will never happen. She just said it for them to go back and of course, she wants to leave Xin.

And day continues as Xin wants, but next day a big problem arrives, Xin who is currently using the Gremory Clan as a hiding place receives an invitation.

The Young Devil Gathering Party and he will represent his own Clan and that is Fei Clan as the leader.

Xin almost forgot this, but still, the training program is just about to end today and his only problem is who the heck will he attend a party and a peace agreement in this form.

He already tries to modify himself because he can only change his physical appearance, not his age.

And not only that, the people and clan that he is trying to avoid will come to that Young Devil Gathering Party and Xin sure that they will find him there even if he hides.
