I'm a doctor, I abandoned all the operators

"How can someone like you be qualified to be awarded the title of doctor?"
"With your abilities, we don't even want to listen to your orders!"
"You are just a piece of shit who can only rely on Amiya to take over the command!"
Because he was an ordinary person in his previous life, Chu Yun, who traveled through time and space and became a doctor, was targeted.
Without much command knowledge, Chu Yun had to do odd jobs silently every day, and even had to endure the operators' contempt from time to time, and devote himself to honing himself.
But what Chu Yun didn't expect was that on the day he was betrayed by an operator and died, he actually returned to the days of working in Rhodes Island, not long after he joined.
But this time, Chu Yun no longer decided to treat the Rhodes Island operators "gently".
"Well, Doctor, please come back. If you don't come back to Rhode Island, you will die. Doctor Kelsey is no match for the Regent!"
Huang looked at Chu Yun in front of him with a pleading look, holding in his hand a photo of Amiya being captured.
"Ah, yes, yes, everything you said is right!"
Chu Yun clapped his hands happily and said with a smile
"But I'm sorry, I'm now the leader of the Reunion Movement, the boss of Penguin Logistics, a shareholder of Kalan Trading Company, and Tracys' most trusted aide, so why should I help you, Rhodes Island, right, Rhodes Island's operator?"
Huang: “!”
