A couple of things happened the moment I had sensed the horrifying attacks came at me. I activated the 'Forth Boost.'
I had not activated it in the battle since I have got the strength of the Grandmaster, but now, the attacks that are coming at me are powerful enough that I have been forced to burn my essence. As the power of the fourth boost burst out, I had merged it with my internal energy.
A single shield appeared in front of me, buzzing with the power of the fourth boost and internal energy, and at the same time, I had activated the copper cleave and swung my sword back.
Time seemed to slow down in front of me, those attacks coming at me with the speed of sonic felt like they are coming at me with the speed of common man, that I could see every aspect of them and it made the horror in my face deepened further.
