The Undead Half-Plane was Xu Tianming's safe house. Whatever he did there, those peeping toms in the God Realm would never see it.
With a flash of light in his hand, the lead box Shadow Douluo had personally given him appeared in his palm.
"Purple Imperial Heaven-Extinguishing Dragon's Spirit Bone. Let's see what it is."
He reached out and unfastened the clasp on the lead box, opening a narrow crack.
It was only a narrow crack, yet it made Xu Tianming's entire body freeze in place.
An incomparably surging aura burst from the gap, instantly making the surrounding space seem to solidify.
The aura was overwhelmingly domineering and violent. Even Xu Tianming, whose physique and spiritual power had long reached the level of a Title Douluo, was somewhat affected.
It took a full quarter of an hour before Xu Tianming finally opened the lead box completely.
An object that looked nothing like a Spirit Bone lay quietly at the center of the box.
The Spirit Bone was entirely purple-black, its surface exceptionally smooth. It looked like a heart-shaped scale.
It was as thick as an ordinary adult's arm, and a strange light flashed across it at regular intervals, as though it were a living creature breathing.
That overwhelmingly domineering and violent aura came from this very Spirit Bone.
"What a tyrannical Spirit Bone..."
Looking at the Spirit Bone before him, Xu Tianming could only be certain of two things.
First, this was the highest-quality Spirit Bone he had ever seen. It was even superior to the seven-hundred-thousand-year right arm bone Snow Empress had sacrificed to him.
Second, this Spirit Bone most likely did not belong to the six standard Spirit Bones. Judging by its shape, it should be some kind of External Soul Bone.
