Two Worlds: The Black Wizard Hides in the Wasteland and Evolves Like Crazy

In a world of wizards, Raven transmigrates as an apprentice to a dark wizard and can only cling to life like an ant. One wrong move, and he'll end up as a test subject on an experiment table. Then, by chance, he gains the ability to travel between two worlds. He steps into a wasteland ravaged by nuclear war. On the first day, he's devastated, thinking he's lost his home. On the second day, he discovers that black bread is worth more than gold. On the third day, Raven staggers out of the Red Waves bar, one hand braced against the wall! On the fourth day, he resolves to get back on his feet. On the fifth day, he realizes the world's rotten. Several drifters with knives corner him in an alley, warmly call him a fellow countryman, then ask to borrow some pocket money. Raven fires two fireballs in response, sending his “countrymen” off to enjoy the afterlife. Who knows how many years later, Raven has become a full-fledged wizard by relying on injections. Looking at the devastated wasteland, where all order has collapsed, he sighs and grabs one of the superhumans, refining him in an instant. This book is also known as: Wizards Need Their Shots. If you won't take injections, why become a dark wizard? PS: Two worlds + dark wizard, no knight breathing techniques + wasteland + stat allocation!
