here is a small clip of me farming chests in CID...
where the chest is when u watch this vid.. it not in the same place... it usually move forwarsd.. but if u just hold left alt down when running you'll see it.. it there is no chest just restart again.. i repeat this 10 times per day. i normally get upto 10/70k per day from it.. depend on the gold / purple items...
