When Han Qiu was setting the array, Zhang Ruochen took out all 172 swords from his Storage Ring.
"I can wield 172 swords at the same time if I use Sword Defending Technique. When fighting multiples savage beasts, at the very least, I can still use this technique to inflict serious damage on them. Of course, that would mean exposing my Heart Integrated into Sword Realm. Is Han Qiu really trustworthy?"
After pondering for a while, Zhang Ruochen put the 172 swords back into the Storage Ring and decided to keep his Heart Integrated into Sword Realm as a secret.
After meeting Chi Yao and Chen Xier, he had gained an even deeper understanding of not to judge a book its cover. Although he had nothing against Han Qiu, he still thought that he ought to keep some secrets to himself and not to show his hand to others.
It was never wrong to leave himself a way out.
