Chapter 4: Life Vs. Lives

My meal is coming and those girls, their minds are slowly slipping from their bodies, while those pathetic creatures crying over their lifeless soon to corpse. It makes me sick. The giant Python smiled as he felt the vibrations of his fat and completely overbearing little brother. The fat panda enter the cave took a deep breathe and yelled into the darkness of his home.

"Let them go Slits!" Po was always trying to get him to do the right thing. It was quite an annoying fact of life, being adopted be the same noodle-loving goose. His brother stepped into his home unannounced again. Behind his brother were vibrations of another creature following him from a distant, about 4ft tall and its arms were longer than its legs. It must be a monkey, with some sort of insect riding on its shoulder. How cute. He brought reinforcements, typical little brother. He couldn't help but laugh at the panda.

"Let them go now. I know you did something. Poisoned them or hypnotized them or whatever you did, fix it now! " Po was so busy talking to the darkness of the cave, he didn't even notice that Monkey, Crane, and Mantis followed him to the cave and was watching from a tress. The giant snake just smiled before turning from his work and said

"Go?...Let who go…you're not making any sense." Po looked furious.

"What did you do to Tigress and Viper?" Po was completely in the cave now he didn't care that one wrong move would make him dinner for the monster he called brother.

"I must have done them a favor, who names their kid Tigress and Viper…Sound like a stripper's name." Slit moved over to the desk where all his experiments were being tested. His 70ft long body made it hard to move around in the cave.

"Why are you doing this? What do you want them for? Do you enjoy making people feel awful? Why would you risk everything dad and I did for you?" Po glared up at the pitch-black creature that was hard to see in the dark cave. He was breathing hard. "Why did you do this?"

"I needed them for medical reasons." He coiled up his body trying not to smile.

"Bull! When I was eight, you set me on fire and you said it was for medical reasons. You really think after that, I would let you for use that stupid excuse on my friends?"

"Of course, it makes prefect sense."

"I'm not playing these stupid games with you. What did you do to Tigress and Viper? How did you do this to them and why? "

"In order alright, I poisoned them using a twiddle leaf, you use the right ingredients it makes a very dangerous poison. How? By putting it in their food. You really shouldn't buy your food from a farmers market; you never know what you are really eating. I fix the gene in the plant so that it's only harmful to female tigers and snakes and since this 'Tigress and Viper' are the only ones in the whole valley I knew I wouldn't miss my target. Tell me Po what did you cook them for dinner last night?" Slits said with an evil smile.

"I…I cooked the usual noodle soup with dumplings…Oh no."

"So tell me Po is a dumpling made of?"

"Twiddle leaves…" Po was so ashamed, his cooking was the reason Tigress and Viper were dying in their own beds. Master Shifu was going to kill him. "I'm never cooking again."

"Oh sure you will, how else am I going to blame you so all the trouble I get into? You know in 2 thousand years I've been alive you are the most helpful idiot I've ever used. I really should thank you someday. "

"Why? Why did you do this to them, they never did anything to you." Po was freaking out. His own brother was using him to kill his friends.

"Because the Valley of Peace is full of idiots. I knew the doctors in this so called village wouldn't know what was wrong with those girls and the farmers won't noticed a young terrified girl putting power onto the twiddle leafs they were selling. It was the prefect plan."

"You scared a young girl to deliver the poison, Why Slits? Not once have you told me why." Po didn't know whether he wanted to kill him or make him suffer first. They didn't say anything for a long time.

"I need the tree snake's venom." Slits finally

"For what? You've got your own."

"Python venom and viper venom are two completely different things. My venoms too strong for this and that waste of scales is the only other snake in the area." Po never knew anything Slits said it was like he was speaking a different language.

"So what's it for?" Po asked still not convinced.

"Medical Reasons." Slits said with a smile

"No seriously, you've never cared about other people you only like being a doctor because of the thrill you get when you fix a problem no one else can. They could build monuments to your self-centeredness."

"You say the sweetest things."

"Tell my what you're going to do with these girls or as the Dragon Warrior I'm going to have to turn you in and you'll go to jail for attacking members of the Furious Five." Po said not in the mood to deal with his brother's little games anymore. Slits busted at laughing, he rolled his head up with joy.

"You? The Dragon Warrior, they picked you…" Slits was laughing so hard he fell backwards. "We're all gonna die."

"Are you done?" Po was getting annoyed

"Not yet" He continued laughing until the moment passed "Okay I'm done."

"What are you doing to these girls Slits?" Po wasn't going to ask again he was getting very angry, very fast.

"I need their DNA. That tiger has a gene in her body that isn't in any other tiger. Gene 14. And as a said before my venom too strong for the excrement so I need her venom." Slits said moving towards his desk picking up a folder with his reach in it.

"For what? Why you need the venom and Gene 14?" Po asked, "What's so important you'd risk everything you've work for?" Slits didn't answer. He was deep in thought. When he finally snapped out of it and moved deeper into the cave to an entrance that leads to a narrow opening. In the opening was a bedroll with a small tiger cub that was sleeping in a ball under the cotton blanket. The poor cub was shriving even though it was about 90 degrees in the cave. He keep sniffing the air like he had a cold, but his nose was dry and he was crying in his sleep.

"Chewy got worst. I need the DNA and venom to save his life just like I did when he was born. So Oh great Dragon Warrior you have a choice. You can send me to jail for attacking your worthless friends and let poor little Chewy die or you can let me go to the Jade Palace and get what I need to save our dying little brother's life." Po was so confused.

If I let him save Chewy what would happen to Tigress and Viper, if we lost Chewy dad would be so heartbroken, I be heartbroken. But I can't lose Tigress and Viper then Monkey and Crane would be heartbroken, not only that they be so made at me. And Master Shifu he'd kill me, but as the Dragon Warrior don't I get say in this? "Well Dragon Warrior are you going to let me save your little brother or do you care more about your replace friends then your own family?"

"I…I don't know."
