Sigrdrifa rushed to the front, spreading her Spirit Force barrier to help Bai Xiaowen block the insect tide.
Fortunately, the passageway was fairly narrow. Sigrdrifa fully expanded her Spirit Force defense, sealing off the entire three-meter-wide tunnel and leaving the insects no gap through which to harass Bai Xiaowen.
The white wave crashed against Sigrdrifa's Spirit Force barrier like waves striking a dam.
"Sigrdrifa, shrink the Spirit Force barrier immediately! Switch from defense to offense!" Bai Xiaowen shouted.
Bai Xiaowen's eyesight was precise. At a glance, he recognized that these tiny insects looked exactly like the giant ice bugs that had appeared on the surface—the Ice Leeches! The difference in size was immense, but they could be regarded as juvenile Ice Leeches.
This meant that the Ice Leech Larvae most likely possessed the adult Ice Leeches' terrifying ability to absorb Spirit Force.
Sure enough, Sigrdrifa's Spirit Force barrier instantly became pitted and scarred, as the massive swarm of Ice Leech Larvae gnawed and siphoned at it, devouring holes of all sizes into its surface.
Sigrdrifa broke out in a cold sweat—if undead creatures could even sweat. She immediately followed Bai Xiaowen's order, contracting her defense while materializing a Spirit-Matter Weapon. This time, she chose a long cavalry saber.
The Spirit-Matter saber slashed out, sending a crescent blade aura carrying tremendous Spirit Force cleaving forward.
However, when the crescent blade aura fell into the swarm of Ice Leech Larvae, it failed to inflict the expected damage. Under the careful observation of Bai Xiaowen's Eye of Evolution, the Ice Leech Larvae actually opened their tiny mouthparts before the incoming Spirit Force attack. Countless mouthparts activated their innate energy-siphoning ability simultaneously!
Although there was a tremendous disparity in energy levels, the Ice Leech Larvae could not siphon away all of Sigrdrifa's attacking Spirit
