Darius looked at Rudra and had to admit that he was the most fundamentally stable and unpredictable opponent he had faced in his entire life.
Rudra was able to go toe to toe with two stronger tier 5 warriors with one of them being the strongest demon general in the entire kingdom of hell and he was not going easy on him at all.
If it were a fair one vs one fight , he was not sure if he had the confidence of killing the enemy which was saying a lot as in the past 200 years the only opponent to have given him any real pressure was the devil Lucifer himself.
He himself was at the peak of tier 5 and on the cusp of breaking through too but the tier 6 promotion test was not something that he could handle which was why he was stuck at the tier 5 realm since such a long time.
To be called the strongest mortal was not an overstatement when describing Darius, yet he still feared facing Rudra alone!
