As the number of clashes increased, Xiao Yan gradually became familiar with these Energy Bodies. The duration of their battles had decreased from dozens of exchanges at the beginning to fewer than ten now. He could even deal with some of the weaker five-star Energy Bodies within three exchanges.
"The amount of energy required to advance between Dou Zun levels is indeed far too immense. The energy I've absorbed during this period would be impossible to attain in even a year outside!" Xiao Yan continued.
"Mm!"
Hearing Xiao Yan's words, Gu Xun Er nodded before saying, "Brother Xiao Yan, your rapid rate of improvement right now is because your cultivation is roughly equal to—or even somewhat below—the strength of these Energy Bodies. Later on, if you want to keep improving this quickly, I'm afraid you'll have to obtain higher-grade Energy Cores!"
Gu Xun Er's meaning was very clear. Four-star Energy Cores and those below them were no longer of much use to Xiao Yan. From here on, he would have to obtain as many five-star and six-star Energy Cores as possible.
As they continued onward, Xiao Yan and Gu Xun Er encountered two Energy Bodies with six-star strength. The moment she saw them, Gu Xun Er became excited. Compared to five-star Energy Cores, six-star Energy Cores would provide a far greater boost to Xiao Yan's strength.
Gu Xun Er swiftly made her move, even using Heavenly Flames. She ended the battle in an extremely short time and obtained two six-star Energy Cores.
"Brother Xiao Yan, these are for you!"
After obtaining the two six-star Energy Cores, Gu Xun Er handed them to Xiao Yan without the slightest hesitation.
"Xun Er..."
Seeing Gu Xun Er hand over the two Energy Cores, Xiao Yan had wanted to refuse, but the words stopped
