There were no 12th generation power cores in Base No.6, one of the reasons why Ji Xinghe had not been able to upgrade. However, 11th generation cores were available. Starting from the 27th generation federal standard-type mecha, all mecha were equipped with this engine as standard. Of the 50,000 active mecha in the federation on the alien planet, more than 20,000 were of the newest models, including the 27th generation standard-type model.
The production of the 26th generation standard mecha had ceased, and they were now only in use like many discontinued cars still running on the roads. Performance lag was an issue, but the bigger problem was the inability to afford new ones. What was available had to be used, like it or not.
