David heard this, a trace of hope flashed in his eyes.
He immediately sought help from the Spirit of the Code: "Spirit of the Code, can you tell us how to solve this plague?"
The Spirit of the Code was silent for a moment, then replied, "The key to solving the plague lies in finding its origin and reconstructing the mathematical system. However, this process is full of risks and challenges. You must be fully prepared."
David heard this and nodded.
He was well aware of the heavy responsibility he carried and understood the importance of this battle.
He took a deep breath and then said, "Reina, we must cheer up. For our civilization and future, we must find a way to solve the plague."
Reina heard this and also tried to cheer up.
She held David's hand tightly, her eyes shining with firm light.
"David, I believe in you. Let's keep going together!"
In the following days, David and Reina devoted themselves to finding the source of the plague.
