1. Kill the Elders & Civilian counsel members in the confusion. 2. Send some shadow clones to help the civilians to boost your reputation so your guaranteed the Chunin promotion. 3. Organise and order some of the panicking & confused genin to help the civilians to evacuate to show you have leadership skills to be a chunin. 4. Have the clones copy other ninjutsu from everyone while helping the civilians. 5. Go help jiraiya with the giant three-headed snake at the gate while copying some of his ninjutsu's.
Jiraiya will be there as well. Maybe copy his ninjutsu too? I don’t remember if it was said that he went on to use sage mode during Konoha Crush, so maybe create a clone to pretend be a powerful sound ninja to bait Jiraiya to use it instead? He can also copy the senjutsu technique specific to the toads like Frog Kata!! Moreover, maybe he should rob a few graves since everyone is too preoccupied atm
