After fusing with the Totem, Meng 37 felt better than ever before. As for the hateful eye in the Totem, there was actually some mention of it in the secret technique that taught him how to deprive Totems.
The eye was said to be the hatred of those who had their Totems stolen away. From now on, each time he further advanced his Totem, he would be disturbed by the hate contained inside, which was a consequence of depriving someone else's Totem.
Of course, there was also a certain benefit to this hatred, as each time Meng 37 utilized his Totem, this hatred would also appear to disturb the minds of others, which would act as an extension of his combat prowess.
"I was able to kill you when you were alive, and you can only support after you're dead" Meng 37 declared with a cruel expression, sensed the overflowing power of his Totem, then happily smiled.
