Touru was in the Liangshan continent. There are 108 star general unleashed in the continent every 108 years. They came from the Liangshan maiden and their goal is to ascend to the maiden mountain. Every star general represent a star in the sky.
In the Liangshan continent, a genius is defined by a star master who is capable of signing star duel covenant with two star general. The star duel is a death game where the star master and it's star general participated, all of them fought against each other and only with will ascend to the maiden mountain and get their wish.
In the vast forest between the border of azure dragon territory and vermilion bird territory, a man and a woman was walking talking in the depths of the forest. The woman looked stunning with her beautiful face and curvy body while the man looks average.
The man and the woman was none other than Touru and Wu song.
It's been a week since Touru arrived in this world. He already checked the system if he could return back to dxd world. And unfortunately the system lied to him, it needs atleast six months of time to be use after arriving to other world.
"Say where are you going?" Touru asked Wu Song.
"I'm going to gather the material needed to upgrade my star weapon" Wu song answered.
"That's boring" Touru said while following her.
"Then!! don't follow me!!" Wu Song said loudly.
"I say you're a very short temper girl, no person will sign a contract with you" Touru said.
"I don't need a master, I alone will be enough" Wu Song said sternly.
"Hais... Well, if you want a star master just asked me and I'm willing to become your star master" Touru sighed and said to her.
Swoosh!!
"Whoa!!" Touru jumped backward as a sword slashed in his earlier position.
"So, that's your motive all along" Wu Song said coldly.
"Calm down, if I really want you to become my star general you will easily become my star general as I could use force" Touru said as he raised both of his arm.
Wu song calm down after she heard what he said.
'He's right, if he want he could easily subdue me and become my master' Wu song thought and she put her star weapon away.
"You.. Just wait till I upgrade my star weapon, I'll beat you to death" Wu Song said before turning around and continue walking.
"I'll look forward to that day" Touru replied as he followed her.
'Hmm.. If I'm not wrong Lin chong was the one who thought Su xing how to cultivate star energy in this world. So probably Wu song know it too.' Touru thought.
'I wonder if she will teach me how to cultivate star energy' Touru thought as he looked at her back.
****
"And why do you think that I will teach it to you?" Wu song said.
"Hmm, because if you don't teach me then I have no choice but to use force." Touru smirked at her.
"Grrrgh, then try it" Wu song gritted her teeth in anger. This man is always bullying her just because he's stronger than her, and how could she face the other sister if her dignity as a harm star was trample by this man.
"Okay, let's do that" Touru said as he stood up and black energy covered his body. 'I'll just use her once again to increase my proficiency in dragon slaying magic' he thought.
The two of them fought once again. Of course like last time Touru beat Wu song. Despite that Wu song was unwilling to teach him. She even said that even he kill her hear she wouldn't tell him how to cultivate.
One after a lot of persuasion that Wu song reluctantly teach him.
****
Half a year have passed by quickly. In this three months Touru cultivated the star energy up to the Nebula early stage. There are six major realms that was known in this world and that is the Stardust, Nebula, Galaxy, Supercluster, Supervoid, and lastly the Annihilation realm. Every major realm consist of three minor stage the early, mid, and late stage.
Currently Touru's star energy reach the Nebula early stage. This stage was enough to become the student of those large sect here in this world.
Touru also help Wu song gathered the materials she need to upgrade her star weapon to two star. Her star weapon now was already a two star star weapon and they already found some materials she needed to upgrade it three star.
"Even though, we haven't sign a contract it feels like I've become your master" Touru said.
"Huh!! Who become my master?" Wu song said. Last time when she upgraded her star weapon to two star she challenged him but like last she suffered an utter defeat under his hands.
Though, Touru have a hard time against her he didn't let her see it on his face. He used his dragon slaying magic and soul force at the same time greatly increasing his battle power with that he managed to beat her. A star general with a two star star weapon is enough to buy time against Supercluster early stage but it still wasn't enough to defeat a Supercluster early stage cultivator. They we're stronger than Galaxy late stage but weaker than Supercluster early stage.
That day she swore that one day she will defeat her and regain her dignity as a powerful star general.
She is the heavenly harm star Wu song the rank 14 heavenly star and she's the previous overlord of the star duels. And now she was being beaten by this man. How could she tolerate it.
"I think I will go now Wu song" Touru said to her.
"Go? Where?" Wu song said. She was confused.
"I will go around and explore this liangshan continent" Touru said while looking at the sky. He stayed at her for half a year and they haven't met a single human in this past few months. He want to go out and know if the timeline already start. If that happen Touru have a reason to complete his mission and slaughter those cultivator.
"Eh? You will leave?" Wu Song asked blankly. She's used to his presence in her journey. He was the only one who she could talk to normally and he's different from those people she met that looked at her like a treasure.
"Hou~ don't tell me, you dont want to leave" Touru said teasingly.
"Hmmph!! I don't care" Wu song said. This man really....
"Then, goodbye Wu song" Touru said as he slowly float in the air.
"Eh!! You're really going to leave" Wu song exclaimed.
"Of course" Touru nodded.
"Oh?! Right, you haven't tell me you're real name" Touru said as he smile to her. He saw her looking straight at him and it seems she didn't want to say anything.
"It seems you don't want to tell me. We will meet again in the near future" Touru smile bitterly and said. He turned around and began to flew away but he heard a soft voice.
"Wu Siyou, that's my real name"
