This prop was acquired by him in that B-grade map, "Death Domain."
It belongs to the globally unique B-grade props.
The effect is extremely powerful.
As long as one wears this prop, their physical fitness will remain at a 5-times amplification over the long term, and if one prays to an Ancient God, one can, after paying a certain price, obtain various powerful strengths.
It is indeed a very powerful prop.
This prop also has an additional effect, which is that after wearing this prop, a buddy called the Ancient God will chat with you nonstop for 24 hours.
Originally, he quite liked this effect.
With Yi absent at times, he could still have someone to talk to. He didn't have many other quirks, except that he loved to chat—a chatty person by nature.
Not speaking for a day made his whole body uncomfortable.
