About the quest
Du San in Ape City is not himself: a snake man bit him and he has gone mad. You track down the snake men, turn their venom into a ticket to Kun Lun and bring back a powder that cures him. Task Master Chang gives the reward at the end.

Walkthrough
| Step | What to do |
|---|---|
| 1 | Accept the quest from Task Master Chang in the Job Center. |
| 2 | Talk to Du San, then find General Judd. He explains that snake men bit Du San and asks you to take revenge. |
| 3 | Hunt the Snakemen in the west of Ape City until a Venomous Fang lands in your inventory. |
| 4 | Give the fang to Pharmacist Dong. He draws a Red, a Green and a Blue Toxin out of it. Combine Blue first, then Green, to be teleported to Kun Lun (see the table below). |
| 5 | In Kun Lun, right-click the 7 stones to collect 7 powders within 5 minutes, or you are sent back to Ape City. Right-click any powder to merge them into Rainbow Powder. |
| 6 | Bring the Rainbow Powder to Du San. He recovers at once and sends you to Task Master Chang for your reward. |
Toxin combinations
Only one order works. The other mixes just play a funny effect on you, so you can try again.
| First + second | Result |
|---|---|
| Blue + Green | Teleport to Kun Lun (correct) |
| Blue + Red | You are poisoned |
| Red + Blue | You recover |
| Red + Green | You grow strong |
| Green + Blue | You float |
| Green + Red | You turn into a zombie |
