Huh? Feng Jun noticed the anomaly and froze for a moment, carefully recalling the flow of spiritual energy just now and the hand seals he had used.
After a while, he cast four more Falling Thunder Techniques in succession.
With the fourth Falling Thunder Technique, the same thing happened again. His spiritual energy dropped by another twenty percent, and a boulder the size of a door panel in the distance exploded with a bang.
"Congratulations, Senior!" Yu Changqing called out loudly. "The spirit art has manifested! Remember to exhaust your spiritual energy."
So this was how he was supposed to exhaust his spiritual energy. Feng Jun finally understood. No wonder. Casting over six hundred Falling Thunder Techniques every time before replenishing my spiritual energy would have been rather tedious.
In fact, this was the more normal situation. Although techniques cultivated during the Qi Refining Stage consumed little spiritual energy, Qi Refining Stage cultivators did not have much spiritual energy to begin with.
It was perfectly normal for several spirit arts to drain one's spiritual energy completely. Moreover, the Falling Thunder Technique consumed more spiritual energy than ordinary techniques. The booklet had noted that long ago.
Feng Jun felt that using five incomplete Falling Thunder Techniques to exhaust the spiritual energy in his body was the proper reaction a spirit art ought to have.
While the memory was still fresh, he cast the Falling Thunder Technique several more times. Of the three attempts, two succeeded.
However, he still failed to control either one. One rumbled more than a hundred zhang above his head, while the other... blasted a chunk off the boulder Yu Changqing had been standing on, a piece as large as a compact car.
Yu Changqing was terrified out of her wits and shot away forty or fifty zhang.
