Happy Trouble

What are elemental techniques? They can be self-created techniques such as Dou Finger, and he would incorporate his understanding of the thunder law to increase its speed and lethality. Or he would add his understanding of the law of thunder and wind to improve the current flashing dash! 

Of course, creating techniques is difficult, and it usually takes decades. But that was for others. Fein had the talent to do that with ease. But that was another project. It would still take months to create one elemental technique, and he can't do that yet with his tight schedule.

After all, Michaels's birthday was approaching, then they still have to find Kidd, and lastly, he had to hunt Jackson to erase the shadow in his heart. 

He doesn't know what happened to Jackson or how strong he was, but with an increase in his strength. Fein felt more assured. This is the reason why he pursues strength. He can only feel rest assured by relying on his own.
