Dong Zhuo is from Xiliang, so what is his relationship with Marten, the satrap of Xiliang?
Xiliang area is a treasure trove of geomantic omen and a battleground for military strategists. This place is rich in good horses, and the cavalry in Xiliang area is also the most powerful cavalry regiment in the three countries. Ma Chao once led troops to defeat Cao Cao in Xiliang area and almost captured Cao Cao alive. It was fortunate that Cao Cao cut his beard and escaped from Ma Chao's gun.
After Cao Cao took power in the Han Dynasty, he always regarded Xiliang area as his own menace. But this place is too far away from Cao Cao, and Cao Cao has bigger things to do, so he has always ignored Marten in Xiliang area. After Cao Cao's defeat in Battle of Red Cliffs, he began to clean up his home front and the west cool area, and regarded Marten as a thorn in his side.
Cao Cao came up with a wonderful plan. He asked Marten's army to attack Sun Quan. Marten's only way to attack Sun Quan was through Cao Cao's defense, so Cao Cao Can took this opportunity to get rid of Marten. If there were no leaders in Xiliang area, Cao further carried out the plan of eliminating Han Sui and Ma Chao. Your home front can be guaranteed, and the whole plan is designed seamlessly. Cao Cao is also implementing it step by step.
