under normal circumstances, it's impossible. Every kind of immortal art and technique has gone through countless years of precipitation in the real world. Countless experts have worked hard to create them. All kinds of immortal art rules interweave perfectly to form a subtle balance. If you want to add even one immortal art rule in it, you will destroy this balance, making the immortal art unstable and collapse.
even universe-grade existences would find it difficult to integrate more rules of immortal techniques, let alone immortal kings. That's something that the Masters of creation researched. However, you might be able to do it with the myriad Dao immortal Sutra and the ten thousand Arts immortal tablet.
