Brief introduction of Borgikinliemen
At first, Wokuotai was chosen as the heir of Guiyouhan. Wokuotai hoped that he would succeed, but failed because of Toregene's interference. Later, he was killed by Mongo on suspicion of rebellion. Shortly after his death, Mongo also died in Fishing Town, and the subsequent chaos and civil war against Khan directly led to the suspension of Xu Liewu's expedition to Egypt.
