Yu Xiaogang and Tang ling agreed to each other's condition.
Soon the competition began Martial soul debate
Tang ling " You can choose the first topic ".
Yu Xiaogang " Since you are doubting my theories lets start with it, the first topic is that Martial soul quality depends on innate soul power, my theory states that higher the innate soul power the higher the Martial soul quality ".
Tang ling " Then Tang san's martial soul is a Blue Silver Grass and it is known as the most useless martial soul in the world then why is his innate soul power level 10 ".
All the people were shocked and doubtful, started doubting that Yu Xiaogang was a lier.
Yu Xiaogang " It..um..uh it is mutated " he stammered. (He doesn't want to reveal about san having twin martial souls to anyone)
Tang ling " No it isn't, it is not even a Blue Silver Grass, atleast not a common one, but definitely not mutated ".
Yu Xiaogang " Then what is it a totally different martial soul which just looks like it, don't say things which you don't know about ".
Tang ling " Yes it is a Blue Silver Emperor, not a Blue Silver Grass ".
Yu Xiaogang " Don't make up things, I have dedicated my life to martial soul research and there is no Blue Silver Emperor in history ".
Tang ling " There is no Luo san pao either, but there is now ".
Yu Xiaogang admitted defeat and Tang ling won the first round.
Tang ling " For the second topic it is about your theory about soul ring age, according to you the first is 423 years old, second soul ring 764 years old,.... etc, but I say that these are bullshit and the age of soul ring depends on physical development of soul master ".
Yu Xiaogang " No it is impossible as anyone who absorb soul ring more than that age will die of soul power explosion ".
Tang ling " There are people with soul ring more than that age, I am one of those people as well " he reveals his soul rings.
Everyone is shocked as before his soul rings were both yellow when registering.
Dai Mubai knew that there were special methods to hide/fake a soul ring's colour but they were rare and only people with white colour soul ring for the first ring would use it but not people with a second soul ring of thousand years old.
Yu Xiaogang " No, impossible, you are faking it " to which ling used his second soul ring on Yu Xiaogang who felt the power was shocked but still accepted his defeat.
Tang ling " For third round the topic is Martial soul inheritance you can tell me how people's martial soul is determined ".
Yu Xiaogang " Yes, according to my research a person's martial soul is determined by the parent's martial soul there are two possibility, first is if one parent has a martial soul of superior quality then the child is likely to inherit it, second is there might be a mutation which is mostly negative, and if not and both the parents have martial soul of superior quality then the child might get twin martial souls but this is rare ".
Tang ling claps " What you have said is true, but you must know that Martial soul inheritance doesn't just depend on parents but grandparents as well there are many cases but I will tell one, once there was a person from Clear Sky Clan who had a son with a mallet martial soul and was not acknowledged by the clan so he later had a son with Clear Sky Mallet as his martial soul, a mallet with properties of Clear Sky Hammer, there are many cases like this in history ".
Yu Xiaogang was inspired and admitted defeat.
Yu Xiaogang " You are superior to me in Martial soul theory and more deserving of the title of ' Grand master ' than me and I admit that I sto..".
Tang ling stopped him mid sentence " You are my senior in both age and experience, there is a lot for me to learn from you but when I was with san he mentioned about you and when I met you I knew that there was arrogance in your eyes and others training was useless as they must improve in their own strengths and make up for their shortcomings but all were receiving same training which further solidified the fact so I just wanted to curb your arrogance and set you in the right path, please forgive me if I did anything wrong ".
All were shocked to hear his words but Yu Xiaogang realised his fault and also knew that if ling wanted to humilite him he would have easily done it with his knowledge but he didn't and only wanted to show him his wrong doings and his respect for ling in his heart increased.
Tang ling " My identity is something which I don't want to reveal and hope you all respect it, I will reveal it when the time is right ".
Tang brothers along with Xiao Wu went to their dorm room and set down to rest from the long journey.
