The nine universes had quite a number of warriors that had ascended to the Divinity but Emperor Heng was the only one to make it back. Soon after his return, he died. He left behind a Forbidden Ground of Elder God and a grand gift.
Sending Relics back from the Divinity could only be done at great cost. Not even God of Sorcerer and God of Barbarian could bear such a cost. Even so, it was not entirely impossible.
Yan Tiangang had sent back some items!
He was the only warrior that sent back Relics to the nine universes and that was also why the Yan Family could become the most powerful family in the nine universes.
Yan Gu had a Relic in his hand and that was sent back by Yan Tiangang for sure. The Divine Resources Yan Gu mentioned was also an item in the Divinity. Divine Resources might be nothing in the Divinity, but it was highly valuable in the mortal world.
