Actually, it's quite simple.
Wei Cheng had switched to the Method of the Agile Swallow.
He had previously unleashed eighteen iterations of Immovable Golden Bells, followed by the Path of Non-Contention, and finally the ultimate phase of the Immovable Golden Bell.
This extraordinary campaign drained all his Moving Mountain inner strength.
If it had been any other Moving Mountain profession, this would be the equivalent of total exhaustion.
But Wei Cheng had switched to the Method of the Agile Swallow in a second's time. As Xu Shan and Liu Sui were burned to a crisp and as Yu Liang and Mei Renli made their move, he rose in the wind, surpassing Xu Shan's agility, vaulting over the fire sea, and catching up to the flame giant.
The entire process came together smoothly and in one breath.
This was possible only because he mastered the second level of the Method of the Agile Swallow.
