All Three Kingdoms Warlords Are My Fathers-in-Law. How Am I Supposed to Fight This War?

(No System, and I'll be drawing some hand-made maps.)

After transmigrating to the Three Kingdoms era, Wei Da becomes Wei Zhongdao. When he opens his eyes, the greatest beauty of the Eastern Han Dynasty is lying in his bed.

As a hardcore striver, Wei Da naturally refuses to lie flat. He spent his whole life working, only to die suddenly from overwork, and he certainly doesn't want to work for those warlords.

Even without a System, he plans to use his identity to build a business in the waning years of the Eastern Han Dynasty. But as he goes along, things take a strange turn.

With his father-in-law among the enemy's hundred thousand troops, Wei Da suddenly has no idea how to fight this battle!

Cao Cao is his father-in-law.

Liu Bei is also his father-in-law.

Sun Jian is his father-in-law too.

Yuan Shao is even his father-in-law.

Even the false emperor Yuan Shu is his father-in-law.

Liu Zhang takes Wei Da's hand and says, "Dear son-in-law, look at that big-eared thief. He stole my Yi Province. How about we join forces and beat him?"

Yuan Shu takes Wei Da's little hand and says, "Dear son-in-law, once I become emperor, you'll be the Grand General."

Cao Cao takes Wei Da's little hand and says, "Dear son-in-law, there's a young woman in Jiangdong who's just come of age. How about we attack Jiangdong together?"

Liu Bei takes Wei Da's little hand and says, "Dear son-in-law, don't listen to them. Hand the emperor over to your father-in-law, and together we'll restore the Han dynasty!"
