The water-blue tunneling light swiftly crossed a large area, ultimately disappearing in a secluded corner.
This place is a valley.
However, it is not where He Song's medicine garden is located.
All the way, He Song traveled via the Blood Escape Skill, but didn't directly land in his herb garden.
Instead, he landed hundreds of miles away and then moved forward through the Earth Tunneling Skill towards the location of his medicine garden.

On one hand, he acted cautiously to prevent being tracked back to his medicine garden.
On the other hand, it provided better concealment and reduced the likelihood of his destination being discovered by others.
Thirdly...
He stayed underground for a while and found no one was following.
Once He Song was sure no one had trailed after him, he resumed the Earth Tunneling toward his medicine garden.
