The tornado generated by low-realm cultivators doesn't have the terrifying power of natural tornadoes and might not even be summoned.
Lin Yifan's realm is in the mid-stage, neither high nor low, so he should be able to summon a tornado.
After carefully pondering and practicing for more than an hour, Lin Yifan could almost summon a tornado.
However, to be on the safe side, he checked everything once more carefully.
After confirming his understanding was correct, he began to exert his cultivation power to create wind.
As the force rotated, the wind gradually formed, and with the increasing speed of rotation, the wind grew stronger.
"Whoosh whoosh whoosh!"
Soon, the sound of the howling wind could be heard in the secret chamber.
However, just when the tornado was about to form, for some reason, Lin Yifan suddenly lost control and couldn't maintain the rapidly increasing wind speed.
In an instant, the fierce wind collapsed and swept outward in all directions.
