Feng Luotian wished to get his hand on this Nine Orb World Bracer, not only because he needed to interfere with the enemies' plan but also because he wanted to use it as a war weapon against the race.
Although he was not planning to use it for his own personal gain, it was already in someone's possession. And the people who owned it were the ones who just saved his life. He was not some traitorous ungrateful back-stabbing bastard who would steal something from his benefactors.
At the same time, he wished that he could persuade the tribe leader to forsake the bracer and not go all-out with the enemies because that would cost them their entire race. However, it would be a direct violation of the wish of the latter's father.
