“30 billion years...”
Qin Mu shook his head. There would definitely be an error if the dragon qilin used this method to measure the growth rings of the Great Black Mountain, but the error wasn’t too big. However, the number of 30 billion years still gave Qin Mu a fright.
One had to know that the number of 30 billion years only referred to the age of the Great Black Mountain. Apart from the Great Black Mountain, this black tree had fifteen other ring-shaped mountains!
If those ring-shaped mountain ranges had similar growth rings, wouldn’t it mean that the growth rings of this black tree was an unimaginable astronomical number?
The entire black tree was incomparably huge, and it was many times thicker than the origin tree. Moreover, it was even older than the origin tree, and the age of the Earth Mother Yuan Jun was only a fraction of its age!
