The main difference between a Twin Martial Souls Soul Master and a normal Soul Master with a single Martial Soul lies in the fact that when Twin Martial Souls Soul Masters switch between their Martial Souls, their soul power quickly fuses with that particular Martial Soul.
Now that Huo Yuhao's spiritual power is sufficiently strong, he can even use both Martial Souls at the same time under certain circumstances. The method of using both Martial Souls simultaneously involves merging part of his soul power with the second Martial Soul, while maintaining the fusion of the rest of his soul power with the first Martial Soul.
This state cannot last long, often only allowing for one or two uses before he must choose just one Martial Soul. Yet, in actual combat, such a method could undoubtedly allow Huo Yuhao to utilize both Martial Souls more perfectly.
