After transmigrating into the villain's daughter, I lie down and win

Jin Yan completed the design and immediately found the eldest princess and her daughter with the drawings.

She handed the things to the eldest princess.

The eldest princess looked at it for a few times, her pupils gradually dilated, and she glanced at Jin Yan in disbelief, then took the drawing over and looked at it with the eldest princess.

"Is this what you did all day and night without closing your eyes?" the eldest princess asked.

Even the eldest princess can see the exquisiteness of this drawing, let alone the "battle-hardened" eldest princess.

When she was young, she liked to dance with swords and guns. After she got married, she often discussed the improvement of weapons with Duke Ding, so she was no stranger to these things.

Therefore, the value of this drawing can be seen at a glance.

Jin Yan yawned, "Well, my grandfather gave me a crossbow arrow before. I was curious about its structure, so I took it apart and wrote down the internal structure."

"And then you made improvements based on it?" The eldest princess also said in disbelief.

If you weren't talented in this area, how could you remember the complicated structure after just dismantling it once?

Not to mention Jinyan is innovative.

Jin Yan nodded, "Listen to dad, something big may happen in Beijing next. He and his brother are in danger. Although my grandfather is in the military camp, he can't guarantee that he will be surrounded by his own people. If this can be done early, it will be better."

We can leave it to them for self-defense, but it’s a pity that the descendants of the Mohist family no longer exist.”

The eldest princess glanced at her confidant, grandma, and soon she went out.

After a while, she approached with a one-eyed middle-aged man.

The eldest princess handed the drawing to One Eye and ordered: "Can we make it in the shortest time according to the drawing above?"

The man glanced at the drawings, and then his eyes fell on Jin Yan.

The handwriting marking the dimensions and introduction on this drawing is clearly the handwriting of the little princess.

Could it be said that this drawing was made by the little princess?

But he didn't ask any more questions, he just said that he could do it.

The eldest princess said: "Then do it quickly."

After the man went down, a familiar figure suddenly appeared in Jin Yan's mind, "Grandma, he..."

The eldest princess nodded slightly, "You are right, he is the descendant of the Mo family around your grandfather."

There used to be many talented people around Duke Ding who were willing to serve the country together, but after years of fighting, many of them were dead.

Those who survived have also been criticized and assassinated to varying degrees due to reasons such as "too cruel methods" and "bloodthirsty".

In order to protect the remaining people, they can only escape by feigning death.

After hearing this, Jin Yan felt mixed emotions.

She didn't ask any more questions, but after knowing that the heir of the Mo family was in the eldest princess's mansion, she went to find him if she had anything to do.

After the eldest princess and the eldest princess knew about it, instead of stopping Jin Yan, they provided a lot of convenience for her to ask the Mohist heirs for advice.

Three days later, the new sleeve crossbows were delivered to Gu Yong and his son and Ding Guogong respectively.

"You said this was made by Yan Yan?" Gu Jinhe looked at the sleeve crossbow handed over by the guard with admiration, and immediately started trying it after he got it.

Seeing Gu Jinhe's finger on the mechanism, the guard was so frightened that he suddenly shouted: "Young Master, be careful!"

Unfortunately, it's still a step too late.

Just hearing the sound of piercing the air, nine arrows had already firmly penetrated into the opposite wall and pillar.

Gu Jinhe, who was unprepared at all, was also hit by the momentum of the sleeve crossbow and staggered back several steps before he regained his balance.

Gu Jinhe's eyes were astonished, and he was about to study the sleeve crossbow, but suddenly there was a chill in his heart from behind.
