Chapter 1684

The expressions of Huyan Gudu and the group of Xiongnu guides changed.

They looked at Wu Ying, who was speaking, and at Gao Yang, who was holding a teacup and drinking tea leisurely, and a terrifying chill arose in their hearts.

Beheaded if deviating by ten degrees?

This is too ruthless!

Even Anna and her younger brother An Aza had their expressions turn solemn.

Once these words were spoken, they must be cautious in their words and actions when identifying directions in the future, otherwise, they might lose their lives!

Gao Yang took a sip of tea and said faintly, "Do not think that I am too harsh. I will not treat any meritorious official unfairly, but I hate deception the most!"

"According to the principle of spherical triangles, for every degree of deviation, the ground will deviate by dozens of miles; a deviation of ten degrees is over a hundred miles!"

"The heads that are cut off will absolutely not be cut off wrongly!"
