Keeping a Diary at Hogwarts, I Somehow Become the Chosen Savior

Jesse transmigrates to Hogwarts as a new Slytherin student. Just as he's feeling anxious, he awakens a Diary-Writing System.

As long as someone believes what he writes in his diary, he can earn rewards.

For his first diary entry, he receives phoenix bloodline, greatly increasing his charm and magical power and granting him the ability to be reborn from the ashes.

For his second diary entry, he receives an invisible beast bloodline, greatly increasing his charm and magical power and granting him the ability to turn invisible.

For his third diary entry, he receives a phantom beast bloodline, greatly increasing his charm and magical power and granting him the ability to cast illusions.

The fourth entry... the fifth entry...

With his Diary-Writing System, Jesse becomes the hidden ruler of the magical world.

Let's set a modest goal: kill Voldemort and become the third Dark Lord!
