I changed all gtc to arkm. After thinking about it, after all, there is an AI conference there. So it is better to choose something more stable and have more concentrated firepower.
The disadvantage of gtc is that the dealer is a bit tricky. Although the long-term is fine, I'm afraid I won't be able to hold it. I decided not to ambush anymore, and I lost two or three points and exchanged the arkm.
