To Su Ming, the thirtieth Sky had long since ceased to be a sky, but was a blade that was placed horizontally in the sky. The gleaming blade was as bright as the sky, which was why it morphed into thirty skies, becoming a ravine that blocked off all those who were not in Boundless Dao Realm.
It was not impossible to cross the ravine, but if anyone wanted to do it, they would require the resolve to sever their Dao. It did not matter whether the Dao they severed was right or wrong, what was important was their resolve!
Tian Xiu Luo thought he had that resolve. He thought he severed his Dao, but when he saw Gu Hong reversing his own Dao in the end and giving up on everything to help Su Ming complete his Dao, he knew that in terms of resolve, he could not compare.
