Yu-Gi-Oh, but using duels to cure problem children!

Bai Luo traveled to a world where playing cards is respected.
And became one of the seven pseudo-Duel Kings at the top of the world? !
Before he could be happy, Bai Luo realized that he only had one set of live twins?
It’s bad, now Zhen De is not worthy of the position.
Just when Bai Luo was worried that he would be killed by the dark duelist that day, he got a system that called itself "Teaching and Educating".
But there is a system that gives out cards as long as you enlighten your heart? !
And enlightening the heart = duel? !
[Mission: Enter the Duel Academy and become a glorious and great people's teacher. ]
[Reward: Satellite Shining·Red Elf]
[Note: Satellite Shining series card tasks will be released later]
You should have said it earlier. I will never lose in a duel!
DUEL!!
By the time Bai Luo came to his senses, he was surrounded by the women.
The card elves were flying around him, and the girls that he had transformed before surrounded him.
Looking at the girls approaching him step by step, Bai Luo couldn't help but sweat dripping from his forehead.
"Wait, didn't they say everything would be fine once we won the duel? What's going on now?!"
