Arc 5Broken Blade Mountain
Chen Mu led the Sword Guardian Battalion in a series of battles that helped save Absolute Sword City, but the Sixth Prince tried to seize his rune weapons afterward. Back at Heaven-Questioning Pavilion, Chen Mu learned new fate and time techniques and gathered with his battalion at the Mission Hall.
- Chen Mu formed the Sword Guardian Battalion and established a fortified base on Broken Blade Mountain, equipping its squads with rune weapons.
- When the Otherworldly Demons attacked Absolute Sword City, Chen Mu led the battalion in destroying their supplies and holding the mountain against Bo Zhu and three Demon Kings.
- Chen Mu launched further raids against the demon army, then led the battalion toward the city during the final assault as Guo Tao and Kong Yu made desperate sacrifices to help them break through.
- Chen Mu's Demon Core Bombs shattered the enemy's morale, and Long Xiang killed Bo Mu before the Valiant Dragon Army drove the demons away.
- Chen Mu treated the wounded battalion, but the Sixth Prince tried to take his weapons and arrest him until Elder Ming intervened.
- Elder Ming recalled the Heaven-Questioning Pavilion disciples, and Chen Mu distributed spirit stones to the battalion before leaving with them.
- Elder Ming gave Chen Mu inheritance jade slips, and Chen Mu studied the Eye of the Seer and Time Stasis before the Mission Hall summoned the training mission participants.
- He Xiao mocked Chen Mu over the attack on Absolute Sword City, while Chen Mu's battalion companions gathered at the Mission Hall and unsettled him.
