Lucky Brain

Easy. 

It was easier than June thought. 

Some of the questions were recycled from the Chinese version of the show, while some were easy enough to guess. It might also be the reason why Zibo was dominating the game.

June quickly wrote down the answer to the question —"If you planted the seeds of a Quercus robur, what would grow?" 

Zibo seemed to be more aware of his presence after June pointed out the math equation he failed to remember. 

Euler's identity. 

To Zibo, who has seen June's grades circulating online, it seemed like June's correct answers were a combination of luck and coincidence. 

Chul was even more bewildered. Seven rounds had passed with over half of the contestants gone, yet June and Jaeyong were still in the running to become the victor. 

June raised his whiteboard—"Trees." 

"Trees!" Kim San exclaimed. "That's the right answer."
