Impossible Situation
Since the undead kept increasing, the most obvious thing to do was use their numbers against them by forming a small tightly-knit circle. This way only a limited number of the undead could attack them at any point and they wouldn't be overrun.
The guards stood on the outside, standing shoulder to shoulder to create a very basic battle formation with Hao Xuan and Han Rong in the center. Even the two injured guards joined in to provide whatever help they were able to.
Han Rong was still constantly using that golden Qi to replenish the guard's energy and heal any minor injuries that got in the way. He closed his eyes and sat down on the ground with crossed legs.
Hao Xuan could feel an extremely intense orb of energy inside Han Rong's chest.
Compared to Hao Xuan's own Qi that was of all different types with different uses, Han Rong's felt like it was a single entity, something beaming with life.
