Chapter 501: Southwest Soldier King

Yin Yang Blast, which Han Sen had practiced for so long, was finally put into use.

Yin Yang Blast was invented by Professor Bai as a method of using strength, and it could be used by people of any status.

Han Sen's conversion rate of the yin force had reached over 95%. Initially, he thought it might take some extra work to get rid of Tie Yi. After all, the yin force could not hurt Tie Yi when his limbs were struck. Only when Han Sen hit Tie Yi where the inner organs were located could Han Sen manage to injure the vulnerable organs.

However, unexpectedly, Tie Yi was so confident in his fitness and Super Diamond Body that he did not try to block Han Sen's punches at all, which saved Han Sen a lot of trouble.

Since it was merely a contest, Han Sen did not have any murderous thoughts. Otherwise, if he had hit Tie Yi's head, Tie Yi would have become an idiot if he was not killed outright.
