An Explosion

Azief remembers that after going out of that world, he swore to himself that he would never tries to open a portal to go to that world again 

His experience in that world is full of dangers. There were many times when he was there, that he had almost die.

Life and death struggle is almost every day. 

If not because he was patient with the torture he endured when he became a slave and bided his time wisely, he might not have such good luck.

At that time, he did not possess the knowledge that he possesses now. Now, he knows. Cause and effect…..how hard it is to be free from this kind of matter

When he travels through time with his sworn brother, they race each other and the speed and momentum they created was so strong it pierces through the time-space barrier.

And in that moment, the Multiversal Convergence starts. Countless of world suddenly superimposed each other and portals to other worlds and other dimension opens.
