"The two rules were established by the Cultivators of the Heaven's Origin Sector at the cost of thousands of people's blood.
"Hundreds of years ago, when the human beings of the Heaven's Origin Sector first started exploring the Occult Orbs on a large scale, the federation nearly collapsed because of the looting of the secret treasures.
"The flourishing and doom of Red Dragon Legion had a lot do with the Occult Orbs, too.
"So, we decided not to reveal all the information of the Occult Orbs to the public. Even many Cultivators knew little about them.
"Occult Orbs, secret treasures, ancient arts… They can be catalysts to push our civilization forward, and they can also be tinder that burns our civilization to the ground."
Li Yao knew exactly what Shangguan Ce was talking about.
