It's not that they didn't want to find a backer, it was mainly that the profits and value of black oil were so immense that they indeed had to be cautious.
After all, it was common knowledge that Ye Corporation would never allow strategic resources like black oil to fall into the hands of outsiders. Thus, the majority of the local production capacity had been seized during the ceasefire. Ye Corporation's fleet had also been constantly scouring the Asteroid Belt, searching for these secret refineries and severely cracking down on black oil smuggling.
Whether it was the fleet or the Security Bureau, or Takamanohara and other companies, naturally, they also didn't want to be strangled by Ye Corporation and have the local black oil supply monopolized. Otherwise, the prices would skyrocket, and in the event of actual combat, one side with oil and the other without would be powerless.
