Li Chen's cultivation was actually like walking a tightrope on the edge of a knife.
It can be said that many of his breakthroughs were extremely perilous, especially in the beginning. Without the guidance of his four grandfathers, he almost relied on unconventional methods to cultivate, and there were many times he nearly became demonized.
However, he never spoke of these matters.
His four grandfathers later explained to him that they didn't guide him because they didn't want Li Chen to follow their old path. They had already proven with their own experience that their cultivation path couldn't lead to the strongest route, and that everyone has their own way of cultivation that suits them, and it might not be suitable for Li Chen.
So, Li Chen simply started exploring along his own unconventional path.
However, unconventional paths also have their advantages, at least there aren't so many constraints to limit his thinking.
