Three Kingdoms: A Ten-Thousandfold Return, Starting with Conquering Jingzhou!

After transmigrating to the end of the Eastern Han Dynasty, Liu Yao becomes the eldest son of Liu Biao of Jingzhou.

After dealing with his elder brother Liu Qi, who tried to kill him, he obtains the Ten-Thousandfold Return System.

Whenever he gives any item to a famous figure from the Three Kingdoms, he receives a return gift.

[Ding! You gave Xing Daorong a fine horse. Returned: 100 Ferghana horses.]

[Ding! You gave Zhuge Liang a bowl of plain rice. Returned: 10,000 bowls of tomato and egg rice.]

[Ding! You gave Huang Zhong a long saber. Returned: 10,000 refined Mo sabers.]

When Cao Cao prepares to lead his army south, he sees the Black-Armored Army, the Mo Saber Corps, and hundreds of thousands of troops behind Liu Yao, and is left utterly stunned.

Liu Yao: "Cao Mengde, if you'd come any later, I'd have been getting ready to march north."
