Baibuqa presented Khurjahus with the strategy for this operation, including the timeframe for ending the war and the benefits that could be gained from it.

Subsequently, Hurjahus sent 60,000 cavalry south into the territory of the Naiman tribe.

Bai Buhua said privately, "This Hurjahu is really stingy. He only sent 60,000 troops. He must still have worries in his heart, fearing that we are no match for the Song army."

Yi Nanchi said, "Having 60,000 troops is already quite good; the Kereit tribe has very strong fighting capabilities."

"Father, I have another plan, but I don't know if I should tell you?"

"speak!"

"Besides getting Hurzahus to send troops, we also need to find Yelü Dashi. He's the one who caused us so much trouble, so we need to get him to send troops too."

"Yelü Dashi is currently hiding in the northern desert. He has always been cunning, so it is unrealistic to ask him to send troops at this time."

“Yelü Dashi must be with Khabul Khan in the northern desert. We can make a request to Khabul Khan (Temujin’s great-grandfather): if he wants to continue to be the king of the steppe, he must act in accordance with the rules of the steppe. At this critical moment, we should no longer provide shelter to Yelü Dashi.”

"Khabul Khan is a man who values ​​his reputation highly. He cares deeply about his glory as the King of the Steppe. Now that the steppe is being challenged by the Han people, it is inappropriate for him, as the King of the Steppe, to hide in the northern desert. I am willing to go to the northern desert to ask Khabul Khan to send troops to fight against the Song Dynasty together."

Yinanchi thought about it for a moment, but he wasn't sure if he could succeed, after all, Khabul Khan was the most powerful man on the grassland.

Besides facing the Song Dynasty, his greater crisis came from the pressure from the Jin Dynasty on the eastern front.

Coincidentally, he and Yelü Dashi shared the same goal, so they came together.
