In an instant, the man with the mustache felt a chill run through his entire body.
Everyone present were researchers and staff with little understanding of the Martial Arts Dao, but as the person in charge of such a significant event, the man with the mustache had a reaction far exceeding others.
"Something's happened!"
The man with the mustache roared in his heart. Whoever dared to infiltrate this place must have some means, and he knew his own abilities in the Martial Arts Dao—taking action was like a mantis trying to stop a chariot.
He reacted swiftly and was about to shout in anger.
"Third Uncle, Fourth Uncle!"
However, just as he uttered these four words, a power unimaginable suddenly surged through his heart and spirit.
The man with the mustache, although not weak in heart and spirit and having reached the Tier Three height, found himself overwhelmed like a fragile boat in a storm by that force.
Whoosh!! Whoosh!!!
