Grandmaster Transformation.

[Radiant Light Dragon].

So that's is what martial soul Yu Xiaogang should've had, huh. Life sometimes really throws a curveball at you, the guy was born with a 'defective' martial soul. Not defective per see I would say it was atrophied, or perhaps he didn't have enough energy to awaken it in the first place?

The number of impurities is almost easily three times his volume speaks for itself, besides being born with an "atrophied" martial soul he spent his whole life trying to cultivate it, literal decades he keep absorbing the energy of the heavens and earth to somehow fight against his destiny. But dues to his 'defective' martial soul the only thing he manages to do was gather more and more impurities.

But now after my [Purify], he was cleansed of the impurities that filled his body and martial soul. And something had to fill the gaps the impurities left, so everything was basically filled with the purest soul energy, that triggered his mutated and defective martial soul to "finish" its mutations, and become what it should have been from the start. The [Radiant Light Dragon].

The [Radiant Light Dragon] probably a variation of the [Blue Lightning Tyrant Dragon], which is also the name of the Yu Xiaogang clan.

Now the previously sickly looking grandmaster that carried bags under his eyes had white hair and carried a sickly tone of voice looked like someone in his late twenties to early thirties. His hair is shiny black and he now portrays a healthy complexion. His eyes now showing a fire that I presume was snuffed out previously.

"Gods... This is..."(Yu Xiaogang)

"Incredible? Life changing? An out of the world experience?"(Aizen).

"Yes... [Radiant Light Dragon], I knew [Luo San Pao] to be a mutation of my clan [Blue Lightning Tyrant Dragon] martial soul, but I always thought it was for the worse..."(Yu Xiaogang).

"Well, you could've probably had the same results if you had consumed three to five immortal herbs, maybe if you found one that is specifically made to dig out potential and cleanse 1 or 2 would've sufficed."(Aizen).

"Thank you. Thank you for... this... "(Yu Xiaogang).

"If you want to thank me teach my daughter well. And don't forget about the favor..."(Aizen).

"I won't... But a favor is just too little to..."(Yu Xiaogang).

"Don't be so certain of it yet. Now I have some other things to take care of. Take this month where I will be training Tang San to get used to your evolved Martial Soul, as Tang San master you will have to accompany him to hunt his first Ring after all. You can also use the opportunity to do the same seeing as you have reached level 30."(Aizen).

"Thank You."(Yu Xiaogang).

"Ah before you have an emotional breakdown, please be sure to call someone to clean the room and go take a bath, you stink right now."(Aizen).

"Oh, alright."(Yu Xiaogang).

After that, I exited the school and joined Zu Ling and Allessa and we had some family time. Tomorrow Zu Ling will have school for real and I don't want to stop that part of her life.

The day passed fast while we were having fun, with my [Observation Haki] I was even able to see the scene between Xiao Wu and Tang San. I guess their meeting is fate, I liked their pairing anyway so I don't have much to talk about it.

The next morning after doing my routine I just teleport to Tang San's bedside and say.

"Good morning my student. Let's the spirit of YOUTH burn bright inside of you! Let's go training!"(Aizen).

Both Tang San and Xiao Wu woke up startled. I simply Picked up Tang San and started running away.

"Don't worry little rabbit I will bring your boy friend back eventually."(Aizen).

Tang San seems a little at a loss of what to do, until a stop on a clearing I and some days prior, it is on the forest relatively close to the city. The cleaning had some essential things for training, a huge and violent river, lots of trees on its border made by yours truly, and of course a bunch of dirty.

"GOOD MORNING my student, let us start with your training. But first, let me explain things a bit before anything. We don't wanna you committing mistakes after all."(Aizen).

"...Ok."(Tang San).

"The first step of the training program will be to break you."(Aizen).

"Sure.. Wait, what?"(Tang San).

"Not on this way. I will increase the effect of gravity on your body in a manner that you will always be straining your body just to move, It's something similar to what my daughter has. Don't worry about wounds and things of the sort, I flood your body with Yang Release so you will heal pretty fast. Understood?"(Aizen).

"...yes?"(Tang San).

"Excellent. Now for physical activities, you will keep repeating the Tang Sect katas, and a bunch of other exercises to raise awareness I have devised. I want you to truly excavate all the potential the Tang Sect martial arts left for you. The second part of your physical exercise will be for you to exercise until your mind falter."(Aizen).

"Falter?"(Tang San).

"Yeah you will be healed and revitalized continuously by my Yang Release, but that doesn't mean your mental tiredness will go away, on the contrary, it will accumulate. But that is what I want, I want you to be so tired mentally that you can't think anymore. And when you reach that state you will start to circulate your [Mysterious Heaven Skill], like that I want to teach you to passively always use your cultivation technique. And we will do it with every skill at your disposition, even blacksmithing."(Aizen).

*gulp*

"For food, you will eat everything mixed with poison."(Aizen).

"Why?"(Tang San).

"I want to Raise the strength of your immunity system, poison, acid resistance, and anything negative I can think of. It will be useful principally to increase your mental power and resistance to attacks that are both physical and spiritual. Don't worry, as long as you are not dead I can fully heal you with my Yang Release. My objective here is to make your body the ultimate weapon."(Aizen).

"... I will do it. Bring it on."(Tang San).

"Good Here is your breakfast. Don't puke and eat everything."(Aizen).

What appeared in front of Tang San is a perfectly healthy breakfast, of course, it's filled with poisons and a bunch of other nasty things, but this doesn't mean that it has to look disgusting.

"Huh, it looks like normal..."(Tang San).

"But it doesn't taste like normal, so chomp, chomp. Go eat we have too little time to transform you."(Aizen).

"YES!"(Tang San).

Tang san really did eat everything, he looks kinda sickly right now but a tap on his head with my [Sun Mark] and he was good to go. We started the training and I will not sugarcoat it, it was gruesome for someone young like Tang San, but the visible results he saw daily was something that can't be denied, his body was being thoroughly transformed from something normal to a weapon.

He didn't falter the boy took the training with a will that most of the current Titled Douluo don't have, his body was repeatedly destroyed and rebuild anew. And at the end of the month, the results are visible.

He grew taller and not just a little bit, muscles that had no place in the body of a six-year-old child were highly defined. In the morning he could drink liquid poison like normal water, and eat rotten food without even an ounce of a problem for the body. Tang San has been reborn on a living weapon.

"Now this month of training has finished and you can finally go back and rest for a bit, I will give you three days of rest before we start the hunt for your first soul ring."(Aizen).

With that, I just tap Tang San on his forehead and he is teleported to his dormitory. and then my clone that ahs been training tang San dispelled sending its memories to me.

Now that I prepared my first guinea pig I guess I can at least choose some good targets for his spirit rings, a snake for a first ring is a pretty good one now I just have to find one that is 1000years or a little bit older. Zu Ling's target has already been chosen, so I guess we could all go hunt toguether.
