This is not comparable to that of the Du family.

The Qian family, even Qian Yuansi, who was determined to become an official, knew all kinds of machine structures in his own hands.

Looking at such a serious and serious lady, Ping'er's eyes were full of admiration.

So what if it is a woman, her eldest lady is no different from a man.

It was her luck to be able to follow such a master.

On the roof, Annuo, who heard the conversation between the two clearly, pulled the corners of his mouth.

This is a big trouble.

Anyone could have thought that this young lady of the Du family was also a ruthless person. After getting the drawings, she actually memorized all the contents on it.

Now they just snatch the drawings back and it’s useless, unless they directly solve the problem of this young lady of the Du family.

The drawings of this loom are not the most troublesome. What makes Annuo the most troublesome is another design drawing placed by the young lady of the Du family.

It is the latest crossbow drawings from another world, and it is also one of the treasures that the other world has paid tribute to the palace this time.

Even the huge and complex loom drawings were memorized, and she didn't believe that the other party would ignore this obviously more important drawing.

Judging from the following situation, it is obvious that the other party has already recorded the design drawing of the crossbow.

Annuo rubbed his head with a headache.

In order to prevent them from being worn by the emperor before they even developed, Qian Chao put a lot of effort into this.

He selected the six-arrow crossbow, a military item that was the most suitable for the old emperor's wishes, from the treasures just developed in another world, and also included production drawings.

This thing can fire six short arrows in a row, with a fast speed and a long range, which is very suitable for arming the Imperial Guards.

In addition to the six-arrow crossbow, there is also a soft armor that Qian Chao was jealous of when he saw it.

This set of soft armor is woven with aramid newly developed by Annuo. It looks no different from an ordinary underwear, but it can block most weapons from harming the human body.

It has better performance than ordinary armor, but it does not feel as bulky as ordinary armor.

The only disadvantage is that the production process is too complicated, so far there is only one piece in another world.

These two things attack and defend, which can be said that Qian Chao gave this gift very carefully.

But what is heartbreaking is that the thing was stolen before it was delivered, and maybe even the credit would fall on others, and they didn't even have the chance to be wronged.

Because the person below has already studied the drawings thoroughly, she can completely say that this thing was developed by her.

Annuo was on the roof until the candle fire below went out before she sighed and left Qinxiang Garden.

The eldest lady of the Du family came to Taining Mansion and even left several of their treasures. Qian Chao had to be notified of this news.

After returning, Annuo sent someone to return to Xingping Mansion with her handwritten letter overnight.

Early the next morning, Qian Chao received news from Taining Mansion.

After reading the news, he looked heavy.

"Dad, what did the letter say?"

Qian Yuansi, who came to greet him, happened to encounter this scene. Seeing Qian Chao's face darkened, he couldn't help but ask.

Qian Chao handed him the letter: "Look at it for yourself!"

After reading the content in the letter, Qian Yuansi's expression also became solemn: "Why is this woman here?"

After fighting with the Du family for half a lifetime, they have fought with Du Yuehua a lot.

This young lady from the Du family is much more difficult to deal with than his father.
