With the Mysterious Wind Explosion Technique, Luo Cheng's speed skyrocketed.
In just one day, he had left the Running Horse Plain.
During this time, Luo Cheng finally understood why the Mysterious Wind Explosion Technique, despite being such a formidable secret technique, was only rated as a Five-star Top Grade!
The fundamental reason lies in its excessive consumption of Essence Energy, making it a heavy burden.
Each time Luo Cheng cast it, it consumed nearly one-tenth of the Essence Energy in a single Essence Energy Mansion!
For an ordinary Awakening Vein Realm cultivator, their total Essence Energy wouldn't even allow them to sustain ten casts.
As such, the practicality of the Mysterious Wind Explosion Technique was significantly reduced.
In a single battle, being able to use it two or three times would already be considered impressive!
Such a drawback naturally prevented its grade from being any higher.
However, Luo Cheng had no such concerns.
