You're a Bit of a Hellish Pet

Lin Bei fell to the ground, and in front of him was a world dominated by spiritual pets! Flying in the sky, running on the ground, swimming in the water, raising and controlling pets is the mainstream of this era! However, Lin Bei, who was unfamiliar with the place and was working 996 a day, was so poor that he couldn't even afford a toad leg. Looking at the hundreds of millions of spiritual pets on the street, Lin Bei swallowed. If you don't have enough life, then you have to die to make up for it! An underworld system that should have been buried long ago, a group of underworld pets dug up from nowhere! I have to say, your book is also a bit underworld!
