Enzo ventured into the primitive era, chosen as a priest by the Crimson Star tribe and emerging as the leader, awakening numerous extraordinary abilities in the process. 
In order to enhance their way of life, extensive reforms became necessary.
Mystical sorcery and modern technology advanced hand in hand. 
While other tribes still dwelled in caves, the Crimson Star tribe had already gained prominence, constructing sturdy brick houses. 
While other tribes were still using primitive wooden spears and stones, the Crimson Star tribe had forged ahead with iron tools. 
In the midst of other tribes worrying about food scarcity, the Crimson Star tribe was reaping bountiful harvests of various grains. 
Furthermore, they possessed an unparalleled army of totem warriors.
In response, Enzo, embraced by the luscious temptress and leading the enigmatic cat maiden, earnestly expressed, "I truly only sought to improve our way of life. How did I inadvertently elevate the tribe into a divine realm?"

Starting from primitive world, building the strongest divine kingdom

At the boundary of the Dark Night Forest .

Harvey spoke again, "I can see that you have an air of nobility about you, definitely from a powerful tribe. And anyone at the border must know about the external realm. If you say you have no money, who would believe that?"

Enzo asked, "Then would wealthy people choose to sneak across with you?"

This question made Harvey fall silent.

He finally realized that Enzo was not the wealthy person he thought he was. Enzo might be a complete native with not a single Kafen to his name.

Realizing Enzo's true status, Harvey's enthusiasm faded instantly.

But Enzo continued to press, "Harvey, do you know how to get through this barrier?"

The barrier at the border was not limited to the area they were in but spanned the entire boundary. Even if one tried to bypass it by sea, they would still be blocked by this barrier.
