Lord Guotin then quickly flew to Yichen and said concernedly: "Kid, since we have taken all the treasures here and didn't leave a single thing for them, this time, they will be enraged and directly come to fight off with us."
"Mn..."
Yichen fell into deep thoughts there.
Indeed, his master was right. If they didn't leave any treasures for them then they would be enraged much and directly come to fight with them.
Furthermore, the two useless treasures that he left made those three old monsters occupied with them and hadn't appeared until now.
This showed that they needed the useless treasures and also didn't dare to confront him head-on which was also to say they feared that he was much more formidable than all of them.
On top of it all, the time taking them to obtain the treasures and to reach there was quite much, that was also to say, those three old monsters weren't able to take away those treasures so easily.
