Several problems about the Stone Gate of Destiny

The reason for deleting SERN data is that the short message sent to the bucket for the first time was intercepted by SERN, which led to the interception of Julun and his party by SERN. The time machine was acquired by SERN.

After deletion, SERN didn't monitor Gunlun, and SERN couldn't control the world without a time machine. Regression beta.

That is, the first message was intercepted, which changed the world line (remember that this message was sent a week ago) and changed the situation at that time. No matter how explosive the text message sent by Gunlun to the bucket is, the bucket will only think that Gunlun's second illness broke out and will not do anything.
