"Indeed, your foundation in the Sword Dao is strong. Clearly, you've practiced extensively."
"However, if you aspire to reach the Rainbow Sword Realm, you need to comprehend more about nature's spiritual energy. After all, the so-called Sword Qi Long Rainbow is about using the strength of one-third sword qi to stimulate seven-tenths of nature's spiritual energy. Thus, your opponent isn't just battling with your sword qi, but against the universe itself."
"My suggestion is to prioritize stability after your Foundation Establishment. Don't use Spirit Stones to enhance your spiritual power anymore, but use cultivation techniques to naturally absorb and cultivate nature's spiritual energy. Once you've grasped the realm of the Rainbow Sword Qi, start thinking about raising your cultivation level."
As Chen Mobai spoke, he motioned for Yu Lian to use the Silvery Sky Sword Qi.
"Yes, elder brother."
