After Ye Zhi's explanation, Gu Yu was suddenly opened, made several clips in one breath and sent them to Ye Zhi, and also took a pen to record its principle and production process, and had the posture for further research.

However, what made Ye Zhi more at ease was that Gu Yu quickly made the wooden plaque she needed, and it was beautifully made and the font was beautiful, just like a work.

"Come, little brother Ye, let's give it a try!" Gu Yu handed the wooden card to Ye Zhi.

In the large room where Ye Zhi specializes in making utensils, there are wood chips and tools all over the floor, in order to let Ye Zhi try the effect, Gu Yu also specially made a wooden sign and placed it five meters away.

Ye Zhi picked up the wooden card, and sure enough, there were three small buttons at the top of the wooden card, and at the lower end of the word "BMW", there were three inconspicuous small pinholes.

Ye Zhi understood, pressed a button, and immediately a silver needle flew out, so fast that it directly hit the wooden board and embedded it.

"Awesome!" Ye Zhi was the first time he had come into contact with weapons in ancient times, and he was extremely happy.

This kind of can be regarded as a secret weapon, even if she is sent by the old man to walk the dart in the future, she can use this to deal with people when she encounters thieves and steals things.

Of course, if you don't like anyone in Yucheng, it is also very convenient to poke his chrysanthemum directly!

"I used to use a bowstring to eject hidden weapons, but today I was inspired by your spring, little brother Ye, a spring is installed in it, you press the button, and the spring inside will shoot out a silver needle, I didn't expect the effect to be better than the bowstring!" Gu Yu was also extremely happy, this was a breakthrough in his career, and the person who brought him a breakthrough was Ye Zhi.

"I really didn't choose the wrong person!" Ye Zhi nodded appreciatively, she can still make a living in the production of small things, and further research and even drawing inferences really requires talented people to make them perfectly.

At first, she was still guiding Gu Yu on the side, but then she was so bored that she went to the pavilion to take a nap, but she didn't expect to wake up from sleep, Gu Yu had already made the horse card, and it completely achieved the effect she wanted.

What a genius!

"Thank you, Brother Gu Yu!" Ye Zhi got the baby, he was very happy, and it was rare to have a little sincerity in thanking him.

"I want to thank you!" Gu Yu took the pen, wrote and drew in the notebook, and hurriedly wrote down his production experience, "Brother Ye, if you have any ideas in the future, come to me more, it's really enjoyable to work with you!" ”

Ye Zhigan laughed twice, this feeling of being cheap and selling well, and gaining trust after getting a baby-

That's cool, isn't it?!

Outside the door, Ah Ping had already obeyed the order to bring the horse to Ye Zhi, Gu Yu and Ye Zhi hurried over and fixed the wooden sign on the horse's head with a clip.

The wooden plaque is just the right size and is fixed in the middle of the horse's head, which does not cover the horse's eyes, but also exposes the buttons and three pinholes on it.

Gu Yu's little servant walked over, saw the two big characters on it, and couldn't help laughing.

"There is such a flamboyant wooden sign, for fear that others will not know that this horse is a good horse!"

Ah Ping glanced at him and spoke for his young master.

"Ma is not arrogant, how can he be worthy of my young master?"

She can complain about her unsuccessful young master, how can this person match?

According to her observation, this wooden sign is definitely not so simple as swaggering, the young master has a lot of flowery intestines, and it is still around!

Ah Ping rarely spoke for himself, but Ye Zhi was moved, and said to Gu Yu:

"Brother Gu Yu, I forgot that my little guy Ah Ping also got a horse, and I will ask you to make a wooden sign another day, with the word "Mercedes-Benz" written on it, and a circle below is divided into three parts......"

"Young Master, I don't need it!" When Ah Ping heard this, he was about to cry, the BMW wooden plate was hung on his own young master, and her horse was hung with the Mercedes-Benz wooden plate, wouldn't she Ah Ping also be on the Yucheng news list?
