As soon as Gu Yong came back, he heard the frightened shouts of the guards.

As soon as he entered, he saw what Gu Jinhe was playing, and his expression became gloomy, "What are you doing?" ”

Gu Jinhe: "......"

Who would have thought that Dad would come back at this time.

He humbly hid his sleeve crossbow behind him, and said cautiously: "Dad, are you back?" What did Your Majesty leave you to say? ”

Gu Yong stared at him with a cold face.

Gu Jinhe couldn't bear his father's knife-like gaze, and handed over his sleeve crossbow.

"This is the sleeve crossbow that Yan Yan sent over, it was improved on the basis of the crossbows she gave her grandfather, my son tried it just now, and the power is very strong, and one of yours is still in the box." Gu Jinhe said.

Gu Yong's face became even more ugly when he heard this, "I know that your sister worked hard to make it, and you are still so wasteful?" ”

“…… I didn't expect so many short arrows to fly out at the slightest touch. Gu Jinhe said honestly.

Gu Yong snorted, his eyes full of dissatisfaction with his son.

But when he got his sleeve crossbow, he suddenly smiled again.

"Prime Minister, there is also an instruction manual here, which was written by the county lord himself." The guard said.

Gu Yong immediately picked up the manual.

He nodded as he watched, apparently getting more satisfied the more he looked.

After reading it, I put the manual back in the box before asking for details.

Hearing from the guards that after Jin Yan returned to the eldest princess's mansion, he designed a sleeve crossbow non-stop, and followed the craftsmen in the mansion to study non-stop, and the old father's eyes instantly turned red.

Those people in the outside world only know that he dotes on his daughter, but how do they know his daughter's intimacy!

Jin Yan wanted to equip the people around Gu Yong with a pair of self-defense weapons, but the time was too short, and there were too few reliable craftsmen, so he couldn't catch up so many pieces at once.

Moreover, for the sake of safety, the crossbow body made for Gu Yong was reinforced with dark iron, and no more iron could be found for a while.

So she soaked in the secret room under the eldest princess's mansion all day long, experimenting with the Mo family, wanting to make a crossbow with leaner materials but higher accuracy and longer life.

"The county lord is doing this now, it looks a little different." The heirs of the Mo family said.

Jin Yan glanced at the semi-finished product in his hand, and admired the other party's eyesight a little, "I just made a little change, and the teacher can see it." ”

Descendant of the Mo family: "That's what I do, even if it's a very subtle change, it can't escape my eyes." ”

Jin Yan kept his hand and said: "This is for a friend, he has been sick since he was a child, his body is weak, and those impulses before are too great, which will bring a great burden to his body, so he made some changes." ”

The heir of the Mo family smiled and said that this friend is really a blessing.

Jin Yan sighed.

Who made Xie Yan grow a good-looking face!

It is destined that Xie Yan has more privileges than others in her.

Two days later, Jin Yan's gift was delivered to Xie Yan's mansion.

Xie Yan was watering in the vegetable shed in the backyard, and when he heard He Ban say that someone from the eldest princess's mansion came, he thought that the eldest princess had some arrangements, so he asked the person to go to tea first.

"Your Highness, it's not the eldest princess, it's the county lord of Changning who sent someone to bring you something." He Ban said.

Xie Yan glared at He Ban after hearing this, "Then you didn't say it earlier!" ”

He quickly cleaned his hands with the water brought by Gonggong Hai, and then looked at the wooden box He Ban was holding with both hands with anticipation and curiosity.

Xie Yan got the wooden box and opened it without the slightest hesitation.

A brand-new sleeve crossbow lay flat in a box, and the slender compartment next to it contained nine short arrows that concealed the cold front.

Under the arrow was a letter, which read: Xie Yan personally opened.
