As a trade-off, he naturally could peruse the Immortal Techniques left by other Human Emperors.
Leaving a self-created Tier Four Immortal Technique would be extremely difficult for other ascended Human Emperor powerhouses, but for Zhang Jian, it was not challenging.
His Taiyin Refining Form Technique and Dream Traveling in the Void Technique are both Tier Four Immortal Techniques.
Moreover, the Soul Capturing Technique and Cyan Lotus Soul Purification Spell have both reached Tier Four, along with the newly refined Little Heavenly Reincarnation Technique, Golden Crow Fission Technique, Yellow Court Blessed Land Technique, Five Dragons Scripture, Nine Dragon Scripture, Nine Revolutions of the Wheel of Time Sutra, etc., all of which can be quite impactful.
His Lifebound Immortal Technique of Mountains and Rivers reached as high as Tier Five.
