The Immortal Technique "Four Seasons Funeral" and "Mahayana" had reached the Ultimate Realm, which also added many insights for Tan Shuchang. He mastered the application of these two types of Immortal Techniques almost to the point of perfection.
Should he face these two types of Immortal Techniques in the future, he could also prepare corresponding defenses in advance.
By then, it could be said that Tan Shuchang's strength had increased dramatically!
And this was all thanks to the great assistance of the Qing Mu Immortal and the two True Immortal ancestors from the Wanchen Immortal Clan. Although the Wanchen Immortal Clan had a long-standing feud with him, they were currently the ones who contributed the most in aiding his cultivation.
It was just unfortunate that, despite the dissipation of three True Immortal Souls, Tan Shuchang still could not glean anything from them. The creation of an Immortal Technique targeting the Undying Nature would still be indefinitely delayed.
