20 years gone in the Valley of Peace. Meanwhile, there were no bandits and plunderers. The Furious Five and the Dragon Warrior were no longer needed. In other words, Kung Fu was dead! That was a nightmare for Po.

Po: *sat on one stage of the training hall and was bored* Ech ...

Shifu: *came to him* Panda, I know, that it is hard for you, but you can't sit here all day.

Po: It's so boring, Master Shifu. No bandits, no criminals and no Kung Fu. I wish it would be like as 20 years ago.

Shifu: *sighed heavily* That's impossible. Unless, you make a time travel. But it's impossible. *walked away*

Po: A time travel? Hmmm... *grinned* Hehehehehehe, Tank you, Master Shifu. You are a genius. Hehehehehehe... *went to the flea market*

At the flea market, he went to the Taihu-pig Lupo.

Lupo: Good day, Ex-Dragon Warrior. Don't say anything. I know why you're here. You want to make a time travel.

Po: How do you know it?

Lupo: Hello! No bandits. No Kung Fu!

Po: Okay. Point for you. I will in time 20 years ago.

Lupo: I know what you need. *went to the warehouse and pulled a bottle out* In this bottle is time travel juice. You must drink it and then you will travel to the past.

Po: Awesome! How much?

Lupo: 300 huan!

Po: 300? Well, Ok. *gave her 300 huan*

Lupo: *took the money* But you have to know that...

Po: Okay! Past, I come! *drank and disappeared*

Lupo: *sighed* ...you shouldn't change anything in the past!
