DFS mining

1. I study engineering. There are two routes, one is a small plane and the other is a robot.
I use an airplane because the cost is relatively low and it can be linked to ah. Of course, it won't sell for a good price. Generally, it costs about 30g, but at least it can recover some of the cost. The small plane requires the number of projects, so the other party has to reach the engineering level and is too lazy to do it. At this time, your proct will have a market
if it's a robot, the cost is a little more expensive, but the advantage is that it can be used. It's still very useful for the crazy group. I hope you can't use it. Ha ha
it's recommended that many of my friends use small airplanes

2. It's no use talking too much, and it's LR to pay for it.

nowadays, the blame is not concentrated and there are many people who are strong at it

3. I have a lot of money, and I can't help you
