Back then, when the various alien races discovered on the True Immortal Battlefields that the Grand Preceptor was absolutely invincible under the same number of Immortal Palaces, they immediately sent experts to assassinate him.
Just like before, when they sent people to assassinate Cao Zhen.
The difference was that Cao Zhen, facing the pursuit of various tribes, disguised himself, gradually developed, and broke through to return at the Peak Immortality Regainment Realm, becoming absolutely invincible in that realm. Naturally, no foreign tribe dared to deal with him on the Immortality Regainment Realm battlefields anymore.
Yet the Grand Preceptor was different; he did not hide from the alien race's pursuit but chose to face it head-on!
In some respects, he was quite similar to Xiang Ziyu.
