After while heroes reunite in huge circular room. they see man standing in centre of room. Man turns to Heroes and smiles. He looks much like Tora but he is older and has grey hair. Man introduces himself and tells that his name is Lao Shu and he´s also member of the assassin cult. He explains that there´s many weak warriors in assassin cult, few strong warriors who are cults sub-leaders and one supreme leader. He tells that those weak warriors are also known as assassin cult´s minions and every leader has his own minions. Now Rei realises why those warriors they fought were stronger than warriors they fought week ago.
Lao Shu sends two of his best warriors to fight heroes. Betrot and Malc angered by death of their master and they attack warriors with incredible power. Rei and other follow and battle is quickly over. Lao Shu is surprised by Heroes battle power and he starts to power up. Ground shakes and Heroes are ready to face Lao Shu.
Heroes attack and try to hit Lao Shu but he evades all attacks. Malc tries to blast Lao Shu but he swats the blast away. Lao Shu flies towards Malc and kicks him back to wall. Betrot rushes to Lao Shu and punches him as hard as he can. Betrot hits and Lao Shu staggers away. now he´s truly angered and he power ups even more. Betrot rushes him again and Lao Shu simply swats him away. Molluk has been gathering energy since the beginning of battle and now he unleashes his blast. Molluk hits Lao Shu but it hurt him just a little bit but angered him a lot. Lao Shu beat Molluk and looks at Rei and sees that Rei, Satsu and Yarek have gathered power since beginning of battle an now they are powered up. They flight towards Lao Shu and fight him. Lao Shu can´t defend against all of them and takes really good hit from Rei. He flies towards wall and staggers to his feet. Now he´s so angry that he decides to use he´s all power to kill Heroes. Lao Shu beat Satsu and Yarek. He looks at Rei who is gathering strength. He strikes Rei but he evades. Lao Shu continues but he can´t hit. Malc and Betrot fly towards Lao Shu and strike him together in both sides of his head. Lao Shu stands still for a while and then falls to ground.
Lao Shu coughs in ground and tells that his death doesn´t mean anything because there is still nine sub-leaders remaining and supreme leader of the cult is invincible. Lao Shu coughs and dies. Now that murder is solved Malc and Betrot decide to go back to their home and train for Tenkai´ichi Budokai which is held after six months.
