Which episode is the combination of Obserro and Saiwen?

What episode is the combination of Obselo and Saiwen? The fourth set of fighting in bosman.

Among the many forms of oberman, there is one that combines the strength of Severn and Ciro at the same time, and that is oberman's brave form (also called parent-child form). So what is the combat effectiveness in this form? Today we will talk about it.

Oberman's brave form is the form that appears in super Oberman fighting, and the finale is the finale. In the play, Obi was defeated when he used the triple form against the necromancer. Later, in order to make Ou Bu fight to the next level, Ciro and Saiwen specially trained Ou Bu.

Ciro created a special space with a glorious form. Saiwen trained Obou for ten years, and then Obou got Saiwen's card. After the integration and transformation, Obuchi's brave form appeared. He has three darts on his head. Finally destroy the necromancer.

Generally speaking, Obi-Wan's brave form is the finale of the play, and it also defeats the undead wizard who has not even destroyed Obi-Wan's triple form. This can show that the combat effectiveness of this form of Ou Bu is higher than other forms.
