Tenku asked Kaede to dig the ground using her abilities after the girl killed the last goblin. He wanted to bury the monsters' corpses, fearing someone would find them and cause panic. Tenku didn't want that to happen because it would disrupt his vacation in the Arashiyama bamboo grove.
After Tenku and Kaede buried the goblins' corpses, they returned to Setsuka and the others. Kaede had contacted her best friend and asked for their location. But in the middle of the way, Kaede suddenly asked Tenku to slow down because she wanted to enjoy the beautiful scenery of the Arashiyama bamboo grove in winter.
On top of that, Kaede had also told him that Setsuka would be waiting for the two, so they did not need to rush. Of course, that was just an excuse for her to be alone with Tenku and spend more time with him.
