This run is the only run in the game that I know of that is actually easier to pull off in musou mode. Guan Yu and Zhang Fei are the only two officers that can spawn in the closest position to the enemy commander, the previous record was set by Zhang Fei however Guan Yu is much faster despite not even being that great himself at speedrunning. However, the weird part is if you use Guan Yu in free mode he will spawn much farther away than in musou which is why I had to go through 6 missions before attempting this. On a side note I do believe this can be cut down further as this was only my first try.
