According to common logic, with the power displayed by this green fragment in the scene, the aging Lord Guardian Hill should absolutely be unable to approach it.
It was even questionable whether Lord Guardian Hill could survive in the Infinite Sea at that time.
But perhaps it was the green fragment's own choice, a destiny foreordained in the unseen.
In any case, Lord Guardian Hill managed to approach the fragment unharmed.
The fragment radiated brilliantly at the bottom of the Infinite Sea, momentarily freezing the surrounding turbulent whirlpool. Because of this, Lord Guardian Hill could traverse layers of obstacles and reach the green fragment.
Subsequently, although the whirlpool resumed its motion, even more ferociously roaring, it could no longer harm the life-enveloped Lord Guardian Hill.
No matter how time flowed or how the world's Tao appeared and disappeared, it could not affect the [Longevity]-bearing Lord Guardian Hill in the slightest.
This is true longevity!
