Germany, compared to Cathay, really isn't that large.
Nevertheless, Germany is a country. Especially with the increasingly severe threat of the demon plague in Europe, deep down, Wen Yu wasn't certain if he could truly act recklessly within Germany's borders.
The reasoning was simple. The overall strength of the Demon Tribe far surpassed that of the Human Race. Despite the Level Lock set by the Dominator and Earth's Will, which prevented Demon Tribe members at Level 5 or above from passing through the Demon Realm's Gate, who knows if there are anomalies among them with Level 5 power, like Tang Haofei or me!
The Human Race has Soul Masters and the Son of Earth profession, so why couldn't the Demon Tribe have something like Devil Masters or Sons of the Demon Realm...?
