Qu Jianlei really didn't expect that the other side would give him such a big surprise—the Earth Attribute Technique "Gravity Field"!
He had studied various attribute techniques. Specifically, when it comes to the Earth Attribute, it's substantial enough, but also very cumbersome.
In the books, he had once come across the notion that the Earth Attribute could use gravity to trap enemies, but there wasn't a specific technique detailed.
Because of this, he even discussed with others on Zarif Star about how the Earth Attribute could perform a Gravity Field.
But most people said that it was fine to just listen to that theory; even if such a technique truly existed, it would likely be something only a Supreme could use.
Even the Spirit Fox indicated that this probably involves gravitational fields or even magnetic fields, maybe it's a combination technique.
