Elf: Evolved from Little Fire Dragon to Fighting Tyrannosaurus

My name is Lin Xuan.I crossed over and even became a little fire dragon!Fortunately, I woke up the lying flat system, and I can upgrade by eating, sleeping, sleeping, and basking in the sun every day!Unexpectedly, my evolutionary route was different, and I could evolve into a battle tyrannosaurus beast! ?...........My name is Xia Lianxing, a champion-level peak trainer, known as the first genius in history!Reborn 20 years before the extinction of mankind, I must reverse the course of history and save the fate of all mankind!Originally, I thought I had conquered a little fire dragon with unlimited potential.As a result, this guy has no interest in cultivation at all, he eats, eats, sleeps and sleeps all day, and even leans on my lap to bask in the sun!Unexpectedly even so!He seems to be getting stronger at the speed of light too!Before you know it, it has far surpassed the beast!Invincible in the world!Also, why didn't my little fire dragon evolve into a fire breathing dragon?What is that human dragon-shaped elf wearing this golden armor?This is too handsome! ?
