Although the Bone Shield summoned by Chen Yu only blocked for a moment, it was enough for Hiromi Jounouchi, who faced the Vermilion Spear head-on.
In that fleeting instant, thanks to the Bone Shield obscuring Maeda Toshiie's line of sight, Hiromi Jounouchi had already retracted her thrust Crimson Stiletto Sword and switched from a thrust to a block, using the sword guard of the Crimson Stiletto Sword to fend off the flying Vermilion Spear.
However, even though she blocked the spear tip, the force attached to the Vermilion Spear still made it difficult for Hiromi Jounouchi to resist.
Even with the physique of a giant dragon, she had not yet fully unleashed this strength, only using a mere two or three tenths of the dragon's power. Facing the spear thrust by the Warring States military commander, she blocked it, but was still knocked back.
