After breaking through to the Heavenly Yuan Realm Late Stage, the next step was the most important one.
Forming the core!
To break through to the Core Formation Realm, the Yin Yang Qi within the body had to reach equilibrium, then merge and condense into a core.
The Innate Yin Sha Qi and Innate Yang Gang Qi Lin Yun absorbed were both the strongest forms of Yin Yang Qi, and that made the difficulty of forming his core even greater.
The stronger the power, the harder it was to control.
The difficulty was like other people merely fusing two ordinary flames, while Lin Yun was fusing two Heavenly Flames—and the two strongest Heavenly Flames at that. As for how difficult that was, just ask Xiao Yan next door! However, the core condensed after such a fusion would also be even more powerful.
Even within the Core Formation Realm, the quality of the core differed. Generally, it was divided into nine stars, with one star being the worst and nine stars the strongest.
What Lin Yun sought was naturally the strongest core.
Therefore, the coming core formation was extremely important and could not be rushed.
Right now, Lin Yun had only absorbed the Yin Yang Qi into his body and had not fully controlled it yet. Although he could attempt to condense a core, there were risks, and if he rushed too much, the quality of the core he formed might be weakened.
Lin Yun did not want something like that to happen. He had already absorbed the strongest Yin Yang Qi, so no matter what, he had to condense the strongest core. Only then would he live up to the system's rewards.
