A sealing technique, as the name suggested, was an array technique for sealing opportunities, space, strength, etc.
The sealing technique Han Fei learned could also be called the Spirit Sealing Technique, which could block the flowing of others' spiritual energy.
If the opponent was much stronger, it wouldn't work.
However, if not, the Spirit Sealing Technique would be of great use.
A split second could decide the result of a fight between two overmatches. As soon as Han Fei activated the Spirit Sealing Technique, the two Half-Mermaid geniuses immediately fused with their companion spirits.
One Half-Mermaid threw up snow all over the sky and summoned weird ground spikes, trying to stab Han Fei from the ground.
Another Half-Mermaid took Chen Aochen's three punches, throwing out its golden harpoon in its hand and piercing Meng Guiyi's defense array in an instant.
Zhao Jiayi yelled and rushed towards the open space on the side.
