Due to some unknown reasons, the thunder vein had taken an extra month to open, so Xiao Yan trained himself to the max. He was made to circle the mountain within 2 minutes every morning and instead of fighting Wudi and Wugong every weekend, he fought them daily. He was always beaten to a pulp and left in a half dead situation. Thanks to his regeneration, he had his injuries cured. He also training his wind technique as he was trying to combine the lightning energy with his wind energy. This reinforced his speed and attack power as it was as if his speed doubled and his attack power tripled. He created three thunder technique.
First was the thunder Dragon. It was a materialized Dragon from thunder energy that carried a lot of force. It consumed a lot of stamina however but thanks to Xiao Yan's regeneration, that part was taken care of. When he finally got it correct, he destroyed a massive part of the mountain.
The second was the lightning judgement. Xiao Yan used his entire body as a lightning magnet. This technique made lightning energy rain down on him or any place he wanted it to. He had to endure countless strikes to get this technique correct.
Last of them was the lightning body. He cloaked himself with lightning energy therefore increasing his sync with lightning. It was like a lightning armour but stronger. He was now as fast as Chanie if not faster. Not even Ja-El now could counter his speed, was what he thought. He never knew that his classmates had become stronger than before.
Wudi and Wugong had to be surprised. Habaek wasn't this good at creating techniques when he was alive. Although it was because he was a lazy Spirit Lord that didn't like stressing himself, but the guy in front of them was diligent to his training and never lazed out. Wudi sometime wondered what good Habaek did in his past to had gotten such an awesome incarnate.
It was the end of the second month and Xiao Yan was noticeably close to a breakthrough but he postponed his breaking through for today, when the thunder vein was about to open.
Immediately the thunder vein showed signs of opening, Wudi and Wugong casted a big barrier that blocked both sounds and auras from from leaking out. They feared that it would bring unnecessary contenders and that was one thing they didn't need right now.
There was a lot of rumbles in the sky as it felt like the heavens were crying for a change to let down it's contents. A 8 feet Dragon Newt who was gonna become a full fledge Thunder Dragon had seen this and roared loudly. His roar shook the mountain as Xiao Yan looked up. He knew that whatever was there was massive.
"Am I seriously gonna fight that? Didn't you hear the roar?"
"Don't worry. We will make sure you don't die. Right now, you need ten Dragon flames or cores in awaken your Dragon bloodline. So take this as a step to start." Wudi patted his head with a smile.
"When the Dragons starts absorbing the Thunder Vein, he is his weakest. That will be the best time to strike" Wugong thought it would be the right time to notify them.
The trio dashed up the mountain as they were headed to where the Dragon was. They made sure to mask their aura and hide it. When they reached, they saw a really big Dragon with blue lightning sparks buzzing around it. It stood as high up as it looked like an insurmountable mountain. Xiao Yan couldn't help but marvel while looking at this perfect creature, at the same time terrified.
Immediately, thunder began raining down in front of the Dragon as a hole was made with a sizzling hot core buzzing with thunder and lightning energy ascending to the surface. The Dragon went forward to take a look at it.
"It just made a mistake. The core isn't complete. Another huge wave of thunder and lightning bigger than the first is about raining down on him." Wugong said with a straight face.
As the Dragon went forward to look at the delicious looking thunder vein, a huge wave of lightning descended in him. He was in so much pain, roaring so much as he couldn't get out out the thunder.
After and hour or two of immense and non stop thunderstorm, the Dragon was so weak. It forcefully swallowed the core as it started merging with his own core. Xiao Yan waiting for when it had completely merged and the Dragon was about drawing power from the core to heal himself before attacking.
After some hours of waiting, there was a glow in the belly of the Dragon that came out. Two core had merged into one releasing great power. As the Dragon wanted to swallow it, someone snatched the core right from his mouth. It was Xiao Yan.
"Who dares to steal my core? Got a death wish?" The Dragon roared as it started breathing thunder bolts at Xiao Yan who stored the core and started maneuvering his attacks. The Dragon couldn't think as it was already incredibly weak. It was on his deathbed as the core was the only way to cure him. He couldn't regenerate without his core and someone had just stolen it.
[Kurogane]
As Kurogane emerged, the Dragon looked at the sword as he was spooked. He looked at Xiao Yan with anger.
"How did you get this sword? What is a Dragon soul doing in your sword? So you're one of those Dragon slayers heh?" The Thunder Dragon used his strength to demolish the mountain below them but before he could do that, his head was already gone flying in the air as Xiao Yan cleanly chopped his his head off.
"Good work Yan." Wudi congratulated
"That was a good fight." Wugong also did the same.
"It was hardly a fight. The Dragon was already so weak before I got to fight him. I may not have been able to kill him." Xiao Yan looked sad.
"Don't forget that luck is also a power. Just say your luck was good. Now what do we do with the Dragon body?" Wudi asked Xiao Yan. Since Xiao Yan was the one who killed the Dragon, he had the right to do what he wanted.
Xiao Yan wanted to saw they should tear it apart and take what was good but suddenly, there was a surge of power inside him.
"Store the body and use the blood to temper yourself and the magic core" said a voice in his head. It was as loud as countless thunderclaps.
"Let's store the body, but is there a way I can use the blood of the Dragon?"
Wudi looked at Wugong with a shocked expression.
"Hehehe...I don't know how you got that idea but that's what I wanted to remind you. If you use the blood of the Dragon that had a lot of celestial essence, it would increase you celestial qui.
The blood of the dragon was poured around Xiao Yan as Xiao Yan ate the core of the Dragon. Suddenly there was a big power surge around Xiao Yan that made shockwaves which pushed Wudi and Wugong far back with a horrific expression on their faces.
"Fuck.. I'm so fucking jealous of this strong magical energy. Our barrier might break if not taken care of." Wudi gave a wrigly smile.
