Lifespan Loot Boxes: From the Start, I Get an Ancient Corpse King Serpent

【Prove the Way Through Slaughter】【Open Snake Boxes With Lifespan】【One Heroine】 This is an age of invasion by countless races! Hundreds of years ago, the countless races invaded, and snake boxes descended upon the world. People must spend their lifespan to open a snake box, then use their own blood to form a contract with the snake inside. Only then can they gain power. In this age, some people open a box and find a Space Snake. Time may be absent, but space reigns supreme! Others find a Gun God Snake and become legendary gun immortals! Still others find a Thunder God Snake and become the very embodiment of lightning! Of course, great rewards always come with great risks! Some people open a box and find a Corpse Tide Snake. When they try to seal a contract with their blood, it turns on them and brings disaster... After transmigrating, Lu Bei was instantly thrilled! Wasn't this the otherworld he had always dreamed of? And he'd discovered that he seemed to have a bit of a cheat ability! He could actually see what kind of snake was inside each box! 【A Lifespan Snake is hiding in this box. It should be fairly easy to contract with. Afterward, you will gain 2.5 seconds of lifespan.】 【An Erotic Snake is hiding in this box. It should be fairly easy to contract with. Afterward, women will become succubi, while men will become CD men.】 【An Ancient Corpse King Snake is hiding in this box. The contract is extremely difficult (but due to your transmigrator constitution, contracting with any snake will be no trouble at all). Afterward, you will gain the bloodline of an Ancient Corpse King.】
