Someone had clearly thought ahead. They needed a Shugenja to drop part of the pass, to slow down the army approaching. And in the city was a Tensai of Earth. So, a messenger had been sent for the ailing shugenja.
Hachi looked over the walls, at the area that needed to be brought down, and frowned slightly. His studies told him what needed to be done. Sadly, his sensei had never taught him the exact prayers needed. Fortunately, he was skilled enough to do it anyways. He hoped. But, to do so, he had to go out to the actual pass. So, he moved out. There were others, attempting to collapse some of the other passes, but Hachi fell quickly behind, moving slowly.
He didn't need any scrolls for this, and called upon the Earth Kami.
It took a little time to make them understand what he wanted,but he was used to the slow pace of them.
Once they had accepted what he wanted, he actually had to convince them to do it. This also took time, where any hypothetical watchers might have wondered why he was staring at the ground outside the pass, muttering at it for long minutes. However, he cared not about his appearance, but about the results.
Which were that he managed to convince the Earth kami the need to collapse the pass. Now that he had convinced them to do so, it was time to call on the Earth kami to do so. It would be the height of his power to do this, outside of a long-term ritual. Fortunately, he had, in truth, achieved the level of being a tensai. He was the other portions of the passes had dropped, and waited just a touch longer, to allow any in danger to get out of it.
Then, he called on the Earth Kami to shake.
Although he was safe from their rage, the kami of the Earth shuddered, shook, and fought! The last portion of the pass collapsed over the course of a single long minute... while Hachi merely waited, safe from the effects of his prayer.
Once it was done, he turned, and began the slow walk back to the walls. Where he had occasionally been talked to by those outside the walls, this time none of them dared approach the slowly moving figure.
