Li Yan also knew that his age was the biggest limitation for promotion.

If you don't encounter Tubo at its peak, there is really no need to worry.

Practicing martial arts, investigating cases, living a comfortable life, waiting to be number one in the world, with full wings, I can kill whoever I want.

I'm just afraid that with such a delay, by the time it can really affect one side's war situation, Datang's military power will further decline.

At that time, one person's efforts are limited.

But then again, the timing makes it seem like there is no hope at the moment.

The prince could not be the real master, Empress Wu was mean and ungrateful, and Li Zhi fell ill and pretended to be dead.

He can't get promoted even if he has made meritorious deeds, not to mention that he really hasn't made any meritorious deeds on the surface.

"How come it's harder to become a fifth-grade official than to kill a first-grade Duke~"

Li Yan sighed secretly, gathered his mood, turned his grief and anger into appetite, and started eating and drinking.

After eating and drinking, he went to the open space in the backyard.

Keep practicing.

With both hands on the left and right, the bow string is taught secretly, and the three strengths are unified.

This case gave him many breakthrough ideas in martial arts. With each move, his skills became more and more refined.

Li Yan was in a happy mood as he was immersed in the gradually increasing pleasure.

It is also the only one that practices martial arts to solve crimes.

At this time, Xu Da came not far away, not daring to disturb and waiting in the distance.

Li Yan slowly gathered his strength and walked over.

Xu Da reported in a low voice: "We found information about the caravan. It belongs to the largest store in Dongshi, and the Dou family is behind it."

Li Yan raised his eyebrows: "Dou's Shop..."

The Dou family is a famous family of relatives.

Starting from Li Yuan's wife, Queen Taimu, to Li Longji's mother, Concubine Dou De, who was secretly executed by Wu Zetian and even the bones could not be found, the Dou family successively married daughters into the royal family and became stronger and stronger, and was later called

"The Tang Dynasty was so noble and prosperous that nothing can be compared with it".

In terms of officialdom, the Dou family is mediocre at this stage. Dou Dexuan, the only prime minister in the Li Zhi period, was asked by Li Zhi about the ancient emperor Qiu when he was conferring Zen on Mount Tai, but he couldn't answer. Xu Jingzong still answered fluently.

However, the family's business is very large, and the goods in the East Market are of high quality and have always been favored by the powerful. The profits are much greater than those in the West Market where Hu merchants are the majority.

Being able to occupy the top spot in a store in Dongshi, you can imagine how rich the Dou family is.

There are even more middle-level officials. The fifth-grade Wannian county magistrate who released Qiu Shenji before was a descendant of the Dou family.

Li Yan fell into deep thought.

What happened in Lady Shu Sanniang's courtyard happened ten days ago.

In just ten days, the woman transformed from the fake mother of a famous prostitute into Dou's shop.

How does this behavior look like a spy?

He reviewed the entire case again and had a vague guess. He immediately thought of the most useful person under his command:
