Before he fought Grek, Chu Nan had actually relied on the data to deduce many specific situations when he fought in his mind. He had even included all kinds of unexpected situations and ensured that nothing went wrong. That was why he had rushed thousands of light-years in three days with Dong Fang's help to take revenge.

Now that Grek's performance did not exceed his calculations, he was naturally calm.

Seeing Grek's palm slapping over, a black aura seeped out from the front of Chu Nan's fist and connected all the black spatial cracks in the space. It instantly dyed the entire space dark and even light could not escape.

Grek immediately discovered that he seemed to have arrived in another space. The spatial energy around him became extremely violent. Even with his powerful strength as a Heaven Control Martial Artist, it was actually very difficult to control it.
