After I've settled things here, I'll return to Luoyang as soon as Huangfu Song arrives.

"Yes, General!!"

Although he was very reluctant to part with her, Lü Bu did not act like a spoiled girl.

After bidding farewell to Zhang Huan, Lü Bu took the map back to his residence and began to silently memorize every marked point, especially the location of Tan Shihuai's lair, which was deeply imprinted in his mind.

After a night had passed and he had memorized the map thoroughly, Lü Bu returned it to Zhang Huan and began training the Bingzhou cavalry in preparation for the upcoming war.

February 20th, afternoon.

While Lü Bu was busy preparing for battle, Tan Shihuai ordered Han Sui to send 5,000 Xianbei cavalrymen, who also disguised themselves as bandits, to a hill fifty miles west of Hulun Lake.

After Li Ru left, Shefu followed Li Ru's plan and dispatched 13,000 able-bodied men to attack the Dingling and Luosha people in the north.

Shefu himself led the remaining seven thousand able-bodied men to guard his lair.

After gathering intelligence on the Northern Wuhuan, the Xianbei cavalry, disguised as bandits, launched an attack on them at night.

Faced with the sudden attack by the Xianbei cavalry, Shefu was caught off guard and was unable to make any effective command. The able-bodied men guarding the camp were quickly scattered and fought on their own.

Although the attacking force consisted of only five thousand men, they were elite troops under Tan Shihuai's command, whose fighting strength far surpassed that of ordinary young men.

This fierce battle lasted until the fourth watch of the night before it finally ended.

In the end, of the seven thousand able-bodied men guarding the Northern Wuhuan camp, four thousand died in battle, and the rest escaped in the chaos. Shefu also died in the melee.

Ordinary herders in the tribe also abandoned everything at home and fled to the border of Liaozhou in the east at the very beginning of the battle.

Thus, apart from the 13,000 able-bodied men responsible for the northern expedition, the Northern Wuhuan also disappeared from the grasslands.
