In a fight against beings that were an entire realm above yours, what exactly would you do?
Others would either run for their lives, and those more proficient would use experience and genius to outsmart these stronger enemies. In the case of Noah, he had no need to run for his life nor even outsmart his enemies- he chose the most direct route of force!
Yes, they were more powerful than him, with their bodies covered by the immense energies one could only feel from an actual star. But as long as he could withstand this power, he could use something that they and nobody else in this Novus Galaxy had- immense reserves of mana unlike anything ever seen before.
With the use of two Authorities, he was able to withstand their dreadful attacks. Now, he would do the one thing that he could to slowly begin tearing down their defenses, and he would do it by no other way than fully utilizing his unique ability and simply spam his skills!
RUMBLE!
