Yale was walking alone while frowning after noticing the weird situation.
After starting to travel alone, he tried to use his Spiritual Sense to detect the presence of his friends, but he failed and didn't detect anyone.
Yale's Spiritual Sense could cover a large area, and not even a Law God would be able to detect it given that Yale used the Origin Path and was also a Timeless Sovereign.
However, the fact that others couldn't detect Yale didn't mean that couldn't hide from him, and that situation seemed like that.
Yale could understand that the groups that he failed to detect were those who were under the protection of those three who rescued them even before Yale' changed the past.
