Siheyuan: Doting on Bai Ling, Leaving the Whole Courtyard Green with Envy

Recently, the Xiongnu invasion had been giving Emperor Qin Shi Huang a major headache.

Later, Xu Fu devoted himself to researching the elixir of immortality, leaving Qin Shi Huang depressed and despondent until he finally died in despair.

The Qin cavalry was hailed as the mightiest force in the world. In theory, the Xiongnu, a mere people from the northern frontier, should have posed no threat at all.

But the reality was quite the opposite. The Xiongnu were northern steppe people, skilled with both bows and blades.

This was a small weakness for Qin. The empire had the strength to destroy them, but the stronger it became, the more cautious it had to be.

A decisive battle with the Xiongnu was no wise move. It would only give neighboring states a chance to take advantage.
