The Martial Emperor originally planned to stay in Zone 421 and wait for his massive army to arrive, intending to ambush the Underworld King at an opportune moment. However, after calming down, he realized the orders he had issued were reckless. Consequently, he rushed back to Demon City.
On the way, he called every Ninth Realm God of War under his command, ordering them to reach Demon City as quickly as possible. He had no choice; he was genuinely worried that the Underworld King would incite them to rebel. Keeping them by his side was the only way he could feel at ease.
"You actually arrived before I did!"
