It's the creature's scale!
Zhong Yue was shocked, he thought, How did the scale broke off? A scale like this strong would have an even stronger owner, so what could break the scales off from it?
As he thought, he was suddenly overjoyed and he quickly rushed toward the scale, Whatever, that has nothing to with me. This scale is definitely a good thing, not to mention its power, just its ability to be able to reflect my flaws and weaknesses will be able to help me improve greatly. This is the best treasure for me to improve myself, my cultivation techniques and skills.
The sun storm has shot the scale out at a great speed, but the Sui Tree wasn't slow either. It has moved like a fish swimming in the waters at a speed increasingly faster toward the scale.
It was hard to get in but way lot easier to get out. It only took half a day for the Sui Tree to exit the sun and enter the space, along with the creature's broken scale.
TN:
Those who are good in the ancient chinese myths should know what these ten suns are already. What a good play the author has pulled out and depicted them in such a way.
For those who weren’t so clear about it:
There was a mythological archer in the ancient days (sometimes portrayed as the god of archery), he is called Houyi, Shenyi or sometimes, simply just Yi. In the ancient Chinese lore, there were once 10 suns that rose from Earth and these suns have take turns and scorched the fields, turning the world into a wasteland. Seeing that the world was suffering, Houyi shot down 9 of the 10 suns, leaving the last one alive.
