When they learned in private that the woman who taught them was actually Liu Wei's wife or concubine, they were incredulous.

It's astonishing that the woman of a Han Dynasty prince could actually show her face in public and teach people to read.

Driven by curiosity, and also captivated by Cai Yan's talent and beauty.

The two listened attentively and learned a great deal about Chinese culture.

Yuwen Lie studied very diligently.

Until the spring of this year, Yao Guangxiao dispatched Liu Du and Li Su to lead troops eastward, and Yuwen Lie was also summoned to accompany the army and was also asked to advise on military affairs.

Knowing his status as a prisoner, Yuwen Lie dared not offer any opinions to Liu Du and Li Su.

Li Su was somewhat more lenient with him, but Liu Du, who was also a Xianbei, was even less friendly towards him.

Now, Liu and Li's army launched a surprise attack on Gaoliu City, overwhelming the Xianbei guards with a barrage of arrows until only a few remained.

Liu Du, however, asked Yuwen Lie to comment on the arrow, as he couldn't just casually offer his opinion.

"General Liu, General Li, the fire outside Gaoliu City is rather sudden. We should send troops to investigate first."

"I deduce that there are other troops nearby!"

Yuwen Lie reminded him.

However, he couldn't be too explicit, for fear of touching Liu Du's sensitive nerves.

During the past six months that Yuwen Lie had been in Hetao, he was well aware that Liu Du was already the brother-in-law of the King of Yunzhong.

"There are other troops? Heh, Yuwen Lie, you're overthinking it!"

"If there were still any soldiers, the broadswords of my Doyan Three Guards would be itching for a fight!"

"The city is almost completely wiped out. Order the entire army to enter the city!"

Five thousand archers formed a rearguard, while three thousand guards led the way into the city.

There were not many surviving Xianbei soldiers in Gaoliu City. The Han Chinese people who were hiding at home noticed the situation and spontaneously called on their friends and family to go out into the streets and run to the city walls.

Upon seeing the densely packed crowd below the city, all of them yellow-skinned and black-eyed, bearing the banners and armor of the Han people, he was immediately moved to tears and quickly opened the gates to welcome them.

Li Su and Liu Du were overjoyed, so they ordered 3,000 Duoyan guards to enter the city first, while 5,000 archers would hold the line outside, and then enter the city.

"Tonight we'll drink hot wine and eat mutton in town, hahaha..."

Liu Du walked to the city gate passageway and burst into laughter, as if he saw a beautiful woman holding a cup of wine and feeding him. His hand unconsciously slipped under the woman's skirt.

Suddenly, screams of agony came from behind:

"Oh no! Someone's attacking!"
