Just as he was worrying, he suddenly felt as if his eyes were deceiving him, and saw a huge black spot appear before him. When he could see clearly, his eyes widened. Because what was flying towards him was no longer arrow feathers that could be blocked by shields, but massive wooden stakes.
The wooden stakes were as thick as columns, flying straight at them.
Zuo Jiang almost instinctively stood up, deflecting arrow feathers while running back, but as he was dodging, all around him he heard constant wailing.
Upon closer inspection, it turned out that these giant wooden stakes weren't just a single piece; they were mixed in with the arrow rain, and flew whooshing into the soldiers gathered in shield formations. Originally, these shield formations were impenetrable, but under the impact of the wooden stakes, the soldiers were blasted away like worms.
