Gu Xun'er was exceedingly brazen.
She came straight to their door and confronted them head-on.
However, it could not exactly be said that Gu Xun'er had gotten carried away. Anyone with a Two-Star Dou Sheng, two Half-Saints, and four Eight-Star Dou Zuns behind them, while their opponent had only a single Half-Saint as their sole guard, would probably confront them head-on.

The other Black Submerging Army soldiers had long since set up a formation around Canaan Academy.
Do not think formations were merely trivial tricks.
From a powerful expert's perspective, it was indeed overestimating oneself for the weak to try to turn the tables with a formation. But formations left behind by the strong were another matter. For instance, the formation left behind by the Tuo She Ancient Emperor could trap Zhu Kun, a Nine Star Dou Sheng. That alone was enough to prove that formations had their merits.

The Black Submerging King was even an Eight-Star Dou Sheng.
Their true strength was certainly not as simple as it appeared on the surface. Formations were one of the trump cards the Black Submerging Army had continually drilled in. A thousand-plus Dou Zongs and several dozen Dou Zuns might find it difficult to trap a Dou Sheng, but trapping a Half-Saint would not be hard.

In other words, Gu Xun'er could not be certain that Zi Yan was with Su Qian.
But there were only so many possibilities.
