The Nirvana Dao behind Ye Chen was gray. It was three hundred meters long, but three thousand meters wide. It had clearly evolved to its limits!
The Immortal Sword Principle was dark black. It was also 300 meters long, and 2,000 meters wide. It was undergoing a transformation, and its aura was gradually increasing.
When a Dao was 300 meters long and 3,000 meters wide, it would reach its limits, after which it would evolve into the embryonic form of its Great Dao.
At that time, it would be 3,000 meters long and 9,000 meters wide. From there, he would continue to perfect the embryonic form of each Great Dao, refining every part of it until it became a true Great Dao. When that happened, he would reach the Semi Divine realm.
The stronger his Daos grew, the stronger Ye Chen's life force and soul power would be. Furthermore, the growth of each Dao required time and effort to nurture.
