The essence of Blood Dao power has already surpassed the Twelfth Tier, reaching the realm of 'Fruit'. It's just that Zhang Chen's skill level is too weak to unleash the formidable power of the Blood Dao.
The Blood God Child is absolutely not something ordinary cultivators of the Yellow Heaven Dao can detect. If it were said that the enigmatic Great Virtuous Master took action personally, Zhang Chen might find it somewhat believable.
Regarding the Great Virtuous Master of the Yellow Heaven Dao, Zhang Chen has always been extremely wary, finding their depth unfathomable. As the founder of a mysterious cultivation system a full jiazi (sixty years) ago, their path is not just the Incense Divine Dao but also incorporates the Yang God Dao. Zhang Chen can hardly imagine how high their cultivation truly is.
Especially since they have been collecting incense from the whole world for a jiazi. To what astonishing level would their strength have risen?
