Luke was in the cave spreading his water qi out in a push motion and then when he let go of it he got flung to the other side of the cave hitting the cave wall and creating cracks all over the wall.
'Ouch, I wasn't expecting that, using my qi like this makes it a lot stronger than before.'
Luke had been training for a couple of days with no breaks. He could now make a blade a couple of inches wide, and it would go through the whole wall without stopping, and he could send himself flying if he wanted to, he also was doing something else. When he would create the water blade that was a couple of inches wide, he could condense it into a blade as small as when he began his training, but the power of this little blade was not to be messed with. He was also doing some more creative things with his water, he made a bubble around himself with dense water, which made a force field of such. He also started trying to make bullets out of the water qi, but he wasn't able to make one powerful enough yet, he was also wondering if there was a way to store water bullets if he were to ever need them for a gun of sorts.
After throwing himself against the wall he felt as though something was watching him, he turned around quickly and made a shield out of water in front of himself very quickly, he wasn't able to cover his whole body because of the limited time.
CLANNNNNG!
A very big explosion of power occurred when the attacker hit his shield and the water qi around him was dancing as if they were excited.
He was holding the shield together with all of his might, but it was about to break and when it did he heard a voice.
"It seems you have been practicing well, but you're lacking in speed when creating shields. If I were really trying to kill you I could just use another one of my tentacles and attack you from behind and you would have no defense."
"Huh, it's you mentor? You really scared me I thought I was a goner when my shield broke. I'm impressive am I, I really am good at this element thing."
"Tch, When I first started training I was already able to make a triple force field around me in no time, you on the other hand can even make one in seconds. Don't get cocky when you really aren't all that good."
"What, and I thought I was doing pretty good."
"It doesn't matter you will get to that point in due time. It is time for your second lesson, this time I will be showing you some techniques."
"What kind of techniques?"
"Well first we will start with a swimming technique, being able to run away is as important as being strong. The technique I will pass on to you is called, 'Swimming Bullet'. It is really simple and you should be able to do it even as a beginner realm cultivator. First, you need to shape your body like a sharp arrow, or bullet in this case."
The whale then look his tentacles and moved them so that they were super straight and touching in the middle, then he moved his posture in a way that he started to look like a straight arrow, "Second, you have to position yourself in the way you want to go because one of the downsides of this technique is that you can't change the way you are going mid swimming."
He change the way he was facing to the only exit in the cave, "Now when you are ready you will use the water qi around you and explode it in a way that propels you forward!" After he said that Luke could see the water qi near him vibrating like crazy, and after a second a huge explosion happened near him and he was flung outside of the cave spinning like crazy and going extremely fast and Luke heard him say one last thing before he got too far away, "NOW YOU DO IT, I WILL TEACH YOU YOUR NEXT LESSON WHEN YOU FINISH!"
Luke was watching him flying in the distance with sparkling eyes, it was too cool!
"I need to try this now! I want to go that fast too!" Luke started to remember the steps you had to take to activate it, first he took his 2 separate fins and stuck them together, and then combined them to look like a twist drill. Next, he put his two paddle-looking fins next to his body as tight as he could and then changed his poster to look similar to the whale, he was already facing this cave exit so he didn't change his position.
Finally, he started to excite the surrounding water qi so much that they were about to explode, and after trying his hardest to explode the water qi, it finally started to detonate, but that was just it, an explosion.
BOOOOM!
A huge explosion started but Luke didn't propel forward like the whale but instead was still inside of the cave on the ground covered in injuries, twitching on the floor.
"WHAT THE HELL WAS THAT! THAT SNEAKY WHALE, HE MUST HAVE EXPECTED THIS! NEXT TIME I SEE HIM I'LL GIVE HIM A NEW ONE. Still, I'm sure that I did something wrong, it must have to do with the way that the explosions went off. If I recall correctly, the whale said something about exploding it in a way that pushes him forward...that stupid whale! How am I supposed to understand it when you give next to no contexed.'
A couple of minutes later.
BOOOOOM!
Another explosion sounded and Luke was left on the cave ground injured and twitching again.
'This is going to be a painful training session.'
