He took the system to travel to a world where he could practice, but why did he need to hand out coupons?
But the upgraded functions of the system are really great. You can't blame him... After all, after lying in bed for nearly ten years, these things are very novel to him!
The system really gives too much!
So he has to work hard to issue coupons and strive to get people from all the cultivation world to help him upgrade the system!
PS
I'll give you a coupon for the irritable cultivator. If you open it, thank you for your patronage. If you think about it carefully, all the money is gone. The irritable cultivator will become an immortal on the spot.
