Yang Song knew there was turmoil beneath the calm surface of the Earth, and after divination, he saw a year after he left Earth, powerful abyssal demons would descend in a large numbers, with a determination to conquer the entire Earth.
The earthlings now were indeed not what they used to be, there were so many powerful warriors now, but it would still not be enough to deal with the abyssal demons.
Yang Song obviously had no time to deal with that, and he didn't want to wait here for one year either, but it was not like there was no way to deal with the upcoming danger either.
There were many methods in his sleeve, for example, he could leave a trace of his Divine Consciousness in a weapon or props, he could also arrange powerful array formations, he could also transfer some of his power to strong people, and so on.
Yang Song took a fancy to a method – the True Clone Spell.
Creation is hard, cheer me up!
