Jiang He might have transmigrated to a world of Qi and martial arts, but the System that he got only provided him with... seeds.

Jiang He had over three hundred foreign pesudo-Overdeities under his command.

A dozen were killed in the battle at the Grand Luo battlefield while sixty self-destructed. Then, after Jiang He encountered the Nether River Patriarch at the entrance of the Grand Luo Battlefield, he had a handful of them self-destruct again.

At the moment, he had 280 foreign pesudo-Overdeities left.

At the moment, they were releasing their auras, sending tremors throughout outer space.

"Enter the Sealing Array and self-destruct!"

Jiang He waved his hand, sending all 280 foreign pesudo-Overdeities into the array.

The thirteen Demi-Saints had just worked together to break down the first layer of the Sealing Array.

Absolutely Vaporized!
