In other words, since entering this space, he hadn't taken a single step forward. From some perspectives, this stairway for Su Tu was endless.
Yet, realizing all this, Su Tu didn't show much emotion. Instead, he gazed at the mountain peak and studied the stairs.
Then, he continued to step upward, progressing step by step.
He could feel that everything in this space was sealed off. He couldn't use his body technique, couldn't break through the space. To climb the mountain, there was only this path.
That is to say, this path is passable. Since it is passable...
"Then just keep walking."
This was Su Tu's thought, with eyes devoid of emotion. To him, moving forward, climbing, these were things he must do, like eating and sleeping.
Since it's a necessity, just do it, without any other emotion.
"His disposition is indeed extraordinary. This stairway is a piece of the Dao torn down by the mentors, infinite and endless, seeming like a road, but in reality, it is the heart."
