The Master of the Realm of Books was also visibly moved.
He knew that although he was at the fourth step of annihilation and in control of the Realm of Books, with numerous experts present here, he was well aware that if he were to fight with Chu Yuan, even if he could expel this man, the Realm of Books would still suffer immense damage.
If it was possible not to fight, it was best not to.
What he most dreaded was, how exactly had this individual found the Realm of Books?
Despite employing his countless wisdom, he could not figure out the reason.
He was confident that even immortals seeking the Realm of Books would cause a great disturbance and he would have ample time to respond; it was not as if Chu Yuan knew the location of the Realm of Books and could enter simply and easily.
And without understanding this point, he felt heavily troubled in his heart.
