Sorcerer Manual

Ash opened his eyes to find that he had traveled to a strange nation of many races, and people were kneeling before him.
Before he had time to adapt to the new identity of the Terminus Observer, he was put to jail – as a cult leader.
In prison, controlled by a high-tech chip, he was unable to use violence. He also lost all his memories due to the time warp.
How could he escape from the prison full of ogres, green-skinned beasts, sorcerers, and elves in this strange nation? And how could he survive the legendary Blood Moon Judgment?
"Ding! You obtained a game system – Sorcerer Manual! It includes an illusory world map, which can predict risks and gains, helping you find advantages and trouble, and greatly improve exploration efficiency!"
"Ding! You obtained Deadly Berserker Sword Maiden! You can share all skills and upgrade together with her!"
"Ding! You encountered an Illusory Vortex! Go straight through the heartland of the Illusory Realm and harvest a lot of experience to create the Silver Wing!"
...
Is this the legendary system? It not only gives me free skills, but also a skillful fighter?
Ash discovered that even though he was in the Otherworld, he could dominate his own destiny with the system, and even...dominate the entire Otherworld!
