Although the Doctor of Truth on the Collapsed Star Railroad is given out for free in version 1.6, it is not free upon being online. There are some conditions. Players need to open the jump in the Doctor of Truth event in the card pool in version 1.6 before they can receive it.
Answer: The reason why I didn’t receive the Doctor of Truth from the Collapsed Sky Railway may be because I didn’t meet the conditions .
1. Players need to open the jump in the Everything Flows event in version 1.6. This jump has not yet been opened, so they cannot receive it.
2. Before the end of version 2.1, complete the development mission Azure Star - a moment of peace in the universe . If the card pool is turned on, the task has not been completed.
3. Then players need to ensure that their account has unlocked the email function.
4. Finally, you can receive the Doctor of Truth in the mail.
