He learned this killing formation from Lian Cang.
In fact, the formation that Lu Ming had set up was not the complete version of the sword whistling Thunder formation.
The complete version of the sword howling Thunder formation was a peak grade level six formation. Even experts at the peak of the spirit sea realm would die if they stepped in. It was extremely powerful.
Lu Ming had spent more than ten minutes in the battle to set it up in a hurry. Naturally, it could not be that powerful, but it was enough to deal with Wang Haotian and the rest.
Wang Haotian, Jiang Taiyou, and the others tried their best to rush out of the formation, leaving five or six corpses in the formation.
"Damn it!" Wang Haotian roared in anger. Not only did he not get the token he wanted, but Wang Kong was also left behind. If news of this got back to the Wang family, it would be a heavy blow to his reputation.
