Thanks to crazy4nc128, and of course true_blue. I really appreciate the good things you tell me.

I saw that they hadn't got there yet, so I decided to go for a ride. I took off my shades and got my bike.
"Hey, what're you doing?"

Tori and Shane just got there.
"Going for a ride."
"Can you even see the track?" Tori asked.
"Yeah. Hey, Shane, hold on to these." I tossed him my shades.
"You sure about this?" she asked.
"Tor, listen," Shane said, "Nothing will go wrong."
"But what about last time?"
"I fixed it all ready."
"Yeah.." But I had already started off.
It had been a while since I've been on this course and I guess I caught an edge, and I flipped, the bike landing on top of me, something burying itself into my chest. I heard screams and gasps, then Tori said, "Nothing will go wrong, huh?"
When they pulled it off, I realized that it was the kickstand of it that had just barely missed my heart, and a broken leg. There was a light shining down on me.
"Man, you okay?"
"Yeah," I said, "Give me a second."
As soon as I had said that, the hurting stopped and the wound closed. I went to get up and Shane offered me a hand up.
"Don't!" Tori said, "You broke your leg."
"It isn't broken any more, look," and I hit it. "See?" I took his had and got up.
"Guys, get back here," Cam's voice said, "I think I did it."
"All right," I said and he teleported us back to Ninja Opts.
"Did you find it?" I asked.
"Yes, and just in time to see your little stunt," Cam said dryly. "Yes, I've found your blood sample, but I still need the rest of the ingredients. Maybe you can help there."
"Yeah, sure."
"Great. Take this vial and fill it with the water. Ten go to the south west harbor, there should be sea weed there. Then go and try to find the ginseng. It looks like this," and he showed me a picture of the plant.
"Okay, be right back," and I disappeared and then reappeared at the spring, and dipped the vial into the waters. Then I went to the south-west harbor and, sure enough, there was the sea weed Cam wanted. I went to the botanical center and found the ginseng.
"Okay," I said, back at Ninja Opts. "I'm back."
"Great, now I need a pot." He went to the back and came back out. Then he dumped the water and blood into it.
"Hey, Hunter, Blake, think you can dry this?"
"Yeah, sure," Hunter said, taking it, then using his ninja powers, he dried the thing easily.
"Good," Cam said as he crumbled it into the pot. It hissed and fizzed from a crimson to a dark greeny color, like forest green.
"Now the ginseng," and that too was fried.
Cam's mixture then turned from the green to a dark blue, almost black.
"One more thing," he said as he grabbed something off the table. "Lemon."
"What's that for?" I asked.
"Just for flavor."
"Oh."
"Let me heat it up a bit," Cam said and he dark blue turned a bright yellow.
He spooned some out into a cup and handed it to me.
"Well," I said, a little nervous, "bottom's up."
I tipped the glass up and quickly drained the glass.
