Chapter 1640: Besieged on All Sides

Backing out of the Selfless Realm, Ye Yuan's eyes revealed a complicated look.

"Senior, it looks like … there's only this last path that can be taken!" Ye Yuan heaved a sigh and said to Dustless.

Presently, Ye Yuan could already enter the Selfless Realm at any time.

However, under the Selfless Realm, Ye Yuan came up with various methods many times and was still unable to create the fourth layer cultivation method.

Over these 300 years, the methods that Ye Yuan derived were no less than several tens of thousands. But not a single one could work.

Dustless nodded and said, "It can only be like this! These few years, you've attempted countless times before, wanting to open up an inner world, but it just doesn't work. Could it be that this fourth layer cultivation method really doesn't need to open up an inner world?"

Ye Yuan's journey of the heart these few years, Dustless naturally took it into his sights.
