As the Demon King, I Infiltrated the Hero Academy

As a subordinate of the transmigration goddess, Lu Fei had an agreement with her.

That is, as long as he reasonably sent 1000 people to another world to transmigrate using a truck, the goddess would go on a date with him and let him do whatever he wanted for a day.

With his performance finally completed, Lu Fei didn't expect the goddess to go back on her word and have a colleague send him to heaven using a truck to complete his quota.

When he woke up again, he had arrived in a continent of swords and magic.

With the benefits of a second transmigration, the strongest Demon King template was activated.

To understand his predicament, Lu Fei embarked on a journey to master martial arts and magic to their extremes and break through the void.

In this life, he vowed to cultivate to become the world's strongest, break through the world's barriers, and return to give that untrustworthy goddess a good spanking.

However...

Things were becoming increasingly strange.

Various lolis and beautiful girls around him were always hindering his cultivation...

When would he be able to ascend to the God Realm at this rate?

For the sake of his cultivation plans, Lu Fei had no choice but to hide his strength and try his best not to be bothered by trivial matters, but... would things really proceed as he thought they would?
