A few days later, in the Batcave, Batman was somewhat dumbfounded after hearing Flash's story. "So you nearly destroyed the world?"
Flash nodded with lingering fear. "Yes. If Mr. Wang and Mr. Thomas hadn't helped me make up for my mistake, the world might really have been destroyed."
"Next time you travel through the Timeline, make sure to inform me."
Batman said solemnly. At the same time, he created a new folder in his mind—How to Prevent Flash from Destroying the World?
Above that new folder were others, such as: "How to Stop Superman If He Goes Evil?" "The Threat Wonder Woman and the Amazonians Pose to the World," and "If Iron Man Develops a Smart System That Threatens the World, How Should It Be Destroyed?"...
And the largest folder was named: Why Has the World Had So Many Disasters Since 2013?
Batman had truly worried himself sick for this world.
"Don't worry, I won't travel through time again. If I do, I'll definitely tell you and Mr. Wang in advance."
Flash nodded repeatedly. Then, he took out Old Batman's letter and handed it to Batman. "Mr. Thomas asked me to give this to you."
"A letter from my father?"
Even Batman's hands trembled slightly. He took the letter, opened it, and carefully read the words inside.
Halfway through, Batman could not help closing his eyes. His heart was filled with emotion, and he even felt like crying. Then, he opened his eyes and continued reading. Soon, he saw the final line and froze.

Bruce, get married and have children as soon as possible.
