Actually, all of Season 9 is set in the future. Upon arriving in the future, it is revealed that the Justice League was unable to change anything because there was nothing on Earth that could counteract the fortress's reactivation. It is learned that the fortress must be revived, and its answer is that someone must inherit the knowledge here. Without objection, the inheritor painfully accepts all the knowledge. The universe will continue its course, and it's impossible to completely disrupt it. However, the birth of a new life could cause a mission error since it cannot be tracked. To prevent this, a decision is made to go back to before its conception, become pregnant with it, and then lead it to another planet where a more powerful monster can bind it. Thus, Seasons 10 and 11 follow.
