Scumbag Earth Tribulation, Extraordinary Bone Structure

The cultivation of the Impenetrable Earth Tribulation Body entered its third level.

If he wanted to train the third level quickly, merely possessing the Four Great Tribulation Powers was no longer enough. He had to take the fusion of Tribulation Powers to a higher level.

And Tribulation Power fusion was truly difficult to train.

Leaving aside compatibility issues such as water and fire being unable to coexist, there was only one question—how many ways could the Four Great Tribulation Powers be fused?

Anyone who had attended high school could blurt it out: C(4,2) + C(4,3) + C(4,4) = ?

Calculate it yourself.

Pairwise fusion was already extremely complicated. Triple fusion was even more so, and completing the fusion of all four tribulations was super complicated. Not to mention that once the Impenetrable Earth Tribulation Body was fully cultivated, another Impenetrable Tribulation Power would be added. Then he would have to go through C(5,2) + C(5,3) + C(5,4) all over again before finally reaching C(5,5).

No wonder so few people could fuse five tribulations into one and cultivate Limitless Tribulation Power. It truly was difficult. Without growing three or five more brains, there was simply no way to achieve it in one stroke.

Fortunately, there were two pieces of good news.

First, the better one became at Tribulation Power fusion, the less mental effort it took to maintain the fusion.

It was like driving. When first learning, one was tense from head to toe, utterly focused, drenched in cold sweat. Just touching the steering wheel was exhausting enough to leave one gasping, and after driving less than two meters, the instructor in the passenger seat would be so hot he wanted to take off his clothes, all while muttering things like, "You turtle son, dumbass, your old man needs a smoke!"
