In the following period, Xu Nian was completely immersed in his insights.
His understanding of gravitational waves also became increasingly clear.
Soon, he discovered that he could actually use the earth attribute element to unleash the ninth level gravitational wave.
With this breakthrough, he was overjoyed.
The nine levels of gravitational waves had been fully comprehended.
Next, as long as he could merge these nine levels of gravitational waves together, he would be able to form the gravity space domain power.
But just as Xu Nian was ready to continue his insights, his allotted time came to an end.
The Profound Argumentation Tower automatically transported him out.
Of course, as Xu Nian exited, Tyrant also chose to come out.
"Brother, surely you have gained quite a lot in this day?" Tyrant said with a smile.
"I did gain something. This Profound Argumentation Tower is indeed amazing. One day inside is equivalent to a year in the outside world," Xu Nian said with a sigh.
