The Qi Regulation Technique of the Void Pierce Stage borrows power from the void to produce the Sea of Qi. When one stands above it, their magic power would be inexhaustible so long as the Sea of Qi remains in effect.
The magic power contained in the Sea of Qi beneath King Ying Long's feet had a total amount of magic power of at least ten Void Inquiry Stage experts.
It was somewhat similar to Ning Fan and his lightning diagram. With this technique, even if King Ying Long faces the great army of the Myriad Treasure Pavilion by himself, he would not exhaust his reserve of magic power and avoid being defeated.
No one below the Void Pierce Stage would be able to break his Sea of Qi.
As soon as King Ying Long displayed this technique, even the two lightning lords, Tai Yue and Mo Lei, felt that they had no chance of winning against him.
However, Ning Fan directly broke this technique apart using his Eastern Ocean Bell.
