The Expert Who Transmigrated into My Body Is a Hardcore Power Gamer, So I Decided to Lie Flat and Live Off Him

I'm a student at the Sanctum.

It's a school built inside a secret realm. Every year, it admits a thousand gifted children from around the world. It has all the world's knowledge and seven teachers. Anyone who earns the approval of all seven teachers and graduates successfully can inherit the entire Sanctum.

But for tens of thousands of years, ha, nobody has ever managed it.

I only came here to coast along, then leave and get a job after graduating. But...

One day, my body suddenly started cultivating against my will. A hardcore power-leveling expert had transmigrated into me! He spends every day leveling up like crazy!

My level keeps shooting up. Whenever he logs off for the day, I use the strength I got for free to trounce geniuses, show off everywhere, and collect admirers, living like the protagonist of the wish-fulfillment novel I'd always wanted.

But one day, he discovered me.

As expected of an expert, he didn't pay me any attention at all. He just made sure I wouldn't interfere with his leveling, then agreed to let me freeload off him!

A full-immersion game suddenly appeared in the world.

To clear it, players had to control the protagonist and help him inherit the Sanctum. They had to pass the tests set by the seven teachers. The game opened once every season, and anyone could participate. The system randomly assigned each player an account in this world: they might become the protagonist's father, a fellow student, or even a passerby who couldn't get into the Sanctum.

But in the thirty years since the game launched, across 120 seasons, no one had ever cleared it.

Because the protagonist was too laid-back! No one could get him to do anything!

Until one day, an account was randomly assigned to the protagonist himself!

The whole world went wild!

Clear it! This time, we're definitely clearing it!

Later, the seven teachers took notice of the expert's excellence.

Luckily, with the hardcore power-leveling expert around, I didn't have to worry about their tests at all.

The bad news: the seven teachers discovered that their excellent student spent half his time every day slacking off.

Ha, it only took a few little probes for me to get exposed! The teachers immediately noticed that their beloved student had me clinging to his leg.

Just as I was about to say goodbye to this wonderful world...

I returned to the moment I'd first entered the Sanctum.

Rows of comments floated past, telling me where to find treasures, where to get quests, where to obtain peerless weapons, and which teachers were the best to pursue. They were all urging me to get to it.

I looked at the teacher on the podium. Beneath his gentle smile, he watched me like a predator. His thoughts appeared as a stream of comments, too.

Come pursue me! Ask me questions after class! Become my disciple! Do closed-door training with me! I've been working for tens of thousands of years, and it turns out it's all because of this kid! This kid is the key to the endless cycle! Damn it! The Sanctum's rules mean I can't break character! If only I'd let this kid scrape by last run! It's over! There's no hardcore power-leveling player this time! We're doomed!

Anyone! Just help him pursue me!

Me: ...No way. I just want to freeload.
