A Semi-Divine Artifact!

The more golden liquid there was, the less pressure Chen would have to endure. Chen Feng was clear about this point. 

The Flying Rainbow Phantom Sword trembled repeatedly as it continued to absorb the golden liquid. Chen Feng's forehead was also filled with dense beads of sweat. He was enduring the pressure. 

Chen Feng could sense the Flying Rainbow Phantom Sword within the golden liquid. It was as if the Flying Rainbow Phantom Sword had reached some sort of limit.

The Flying Rainbow Illusionary Sword continued to transform as it continued to absorb the golden liquid. Chen Feng could clearly see tiny patterns flickering on the surface of the Flying Rainbow Phantom Sword. The patterns made the sword look extremely ancient.

As the Flying Rainbow Phantom Sword transformed, Chen Feng clearly felt a dense pressure enveloping his heart. His heart thumped slightly. 

However, Chen Feng did not panic.
