On Friday, the final exams at every institute were declared over. Large numbers of students gradually dragged their suitcases out of the campus gates and stepped into a refreshing winter vacation.
Now that they had some free time, the 493 challengers from the Brain Institute and Bioengineering Institute launched a full-force assault on the difficult problem!
Each class had established a challenger group chat. A crowd of hot-blooded students gathered there to discuss the problem and share the papers they had collected, keeping themselves frantically busy day and night!
But the real problem couldn't be solved through brainstorming alone. The time limit was three days, and two days and two nights soon passed without a single student solving it!
In the early hours of the third day, morale in one of the Bioengineering Institute's group chats finally plummeted.
"I give up. I really can't solve it. I've transferred the hundred yuan to Xia Wansan!"
"Same here. I haven't slept for two days and two nights. I'm about to die suddenly. A bet's a bet—pay up and go to sleep!"
"Don't! There's still a day and a night left. We still have a chance!"
"What chance? It's all a damn blind spot in our knowledge. I've studied for ages and still can't understand the approach to the problem. This isn't something humans can solve!"
"I shouldn't have acted on impulse. My liver's about to explode, and I still haven't figured it out. Is Song He crazy? Final exams are supposed to be a formality, but he actually set such a difficult problem?"
"Why are you all chickening out? Get yourselves together! This concerns the reputation of our Bioengineering Institute! The whole school is watching! We can't lose to the Brain Institute again!"
"Well said! Then tell us, how do we win?"
