"Our ancestor was from the Three Thousand Worlds, and they made their way to earth, but your ancestors were strong and powerful. There was also another group that helped with the attack. They were like the leaders of this universe. The fight extended up to outer space," Yvidie narrated.
He continued, "And then, your people were outnumbered, and they chose to sacrifice themselves to block earth from the Three Thousand Worlds. The seal was so powerful that we're still finding a way to break through it."
"I see." Jacob nodded thoughtfully. It seemed to him that some hidden tribes were also from the Three Thousand Worlds, They didn't want to stay on earth but they were prevented from getting out because of the seal.
