Louis just felt goosebumps all over.
Though the Nightmare Sword: Jade is much weaker compared to some subsequent Steel Soul flow martial techniques.
After all, it's only a level 1 martial technique.
But precisely because it's a level 1 technique, there is a chance to integrate basic techniques into every attack, making normal strikes comparable to skills.
This kind of operation, Louis had seen a long time ago.
Instructor Jino's Jino Breathing Technique is a typical example.
By integrating the temporarily explosive breathing technique into daily breathing, one keeps themselves in an explosive state at all times.
To this day, Louis has only managed to maintain the Jino Breathing Technique for 4 hours in a regular state.
It's not that he can't learn it, rather his body's strength is not yet able to support maintaining the Jino Breathing Technique for a long time.
