Su Xinyi's eyes lit up, whether it was Yulin Guard or Zhangping Mansion, these places bordering the Tatar had friction all year round, and small-scale battles were unending, causing serious attrition to horses.
She had heard the prince mention this problem before. Even the Ministry of Imperial Stables in the capital had done their best to raise horses and buy them from all over the country. However, it was actually difficult to provide enough horses for border defense.
This was great news for her. She didn't care about exchanging these horses for other valuable items anymore, as her mind was entirely focused on the horses right now.
Her cousin's letters always brought good news instead of bad, so she went on to read Cao Qing's letter. Cao Qing's letter was similar to her cousin's, just with more detailed descriptions of their transactions. She then read Tian Zao's letter, in which he included a letter for Zeng Liang, asking Su Xinyi to pass it on.
