After all, he really didn't have a secret regarding the technique's missing portion, he only wanted to cultivate it for this abstract and easily ignored 'all rivers flow into the ocean' effect that would allow him to connect and Resonate his soul with the dimension Earth was in. He also naturally didn't know the fact that the old man had given him a benefit in allowing him to stay longer.
