Chapter 2: The Dragon Lake.
A year has passed since Qi received the flask. He found no use for it, for he could not remove the blocker. His mother made him a leather belt, so he didn't have to carry it in his hands all the time.
His lack of earth bending gained him some enemies. The other children were jealous of his fame, and earth bended at him at every chance. He always came home dirty and covered with sand. His best friend, Buko, was also an earth bender. He was quite good, for Qi shot him a look of envy every time he levitated a rock. Buko learned not to earthbend around Qi.
One day, the bully leader, Tai, was especially angry at Qi after he sent everyone a sugar dumpling that morning.
"Come back here, you coward!" bellowed Tai as he and his possy chased Qi down.
"What do you want with me!" though Qi knew the answer.
"We're gonna teach you a lesson!" and with that, Tai closed his hand into a fist, causing a rock to pop up right under Qi. He stumbled and tripped, right into the bushes, rolling down a hill hidden by shrubs and trees. He could hear laughter behind him as he rolled farther away from them.
He rolled for quite a while.
He stopped rolling. He looked up. A giant stone gate was blocking his way. On the gate were tubes shaped like wavy lines with three swirls on top, like a wave. A water gate. "What's a water gate doing here?" He thought.
Then he realized three trumpet shaped openings were at the beginning of each wavy line, and at the end of each swirl was a sphere. This was not a normal water gate. It was a water bending gate.
For the next few days, Qi tried to fill the water gate with water. It succeeded. When all three spheres were filled, they disappeared in a hole in the wall. After a few moments, the stone gate slowly slid open, revealing a large lake with water.
Pure water.
