Zhao Changhe really had become addicted to combat, that bout he scheduled with Lei Zhentang was not just tough talk, he truly wanted to fight.
Even knowing he might not win against someone practicing the Blood Evil Skill, that's just the way a man becomes with Blood Evil raging within him.
Luckily, he managed to suppress that itch for action, or else the red in his eyes would have been impossible to hide.
In fact, wielding the sword and suppressing the Blood Evil Skill meant that Zhao Changhe could only perform at half his normal strength, but Zhao Changhe found it surprisingly enjoyable. It was somewhat akin to the feeling of cutting a swath through the Kunlun Secret Realm, facing all manner of new situations, wracking his brain to apply the skills that were seldom used on ordinary days. That burst of inspiration and clash of passions was difficult to experience amidst the frenzy of the blade.
