Life Ring

The ring was made of a dull gray metal, with a green gemstone wrapped by a metallic serpent. 

Peering inside, Sheng Tian found that the space the ring contained carried an abundant amount of life force, the power that can sustain life. 

Any realm must have this energy in order to hold even the most basic of life forms. If not, then everything from plants to magical beasts, mortals and immortals, they would all die within a millisecond without error.

For this ring to possess life force meant that it was a life ring, which can be used to house all sorts of lifeforms, including humans and half bloods, for a short amount of time. The amount of time one can spend inside the ring would depend on the amount of life force contained in it.

The aura this ring emitted was at the Origin grade, and with the amount of life force it contained, Sheng Tian estimated that it can hold over a hundred live beings inside for around half a year.
