The Strange Asiatic Apple Douluo

Following the elevation of her cultivation base, her battle armor was upgraded to two-word armor. She made her battle armor using the usual soul master's method to amplify her martial soul. 

However, she discovered an issue when her cultivation base reached seven rings. 

The Asiatic Apple was of the highest grade out of all poison attribute martial souls. On the other hand, the amplification effect on strong poison from battle armor was not that great. After testing, she discovered that her Nine-heart Asiatic Apple's would be as potent as any poison could possibly be once she cultivated the Title Douluo-rank. In other words, the amplification of her battle armor could only be used to amplify the range of the poison's effects at most, but not the strength of the poison. 

If that was the case, it was of little use to her.
