And as soon as Ye Muchen returned to the study, he sat down at the desk, and Beiyu came out of the shadows, put the secret weapon that Ye Muchen handed over to him last night on his desk, and lowered his head to report respectfully.

"Master, my subordinates have searched the entire imperial city, and found that no one in all the ironshops and iron bureaus has produced this kind of boomerang, but I got the news from a blacksmith who made iron, and he said that it was two days ago that a woman took a drawing and asked him to build it."

"Woman?" Ye Muchen stretched out his hand to pick up the red boomerang, observed the peculiarity of the boomerang with his eyes, and asked, "Do you know the name?" ”

"No, the woman didn't say her name." Beiyu's lowered eyes flashed with a fluctuation, "However, the subordinate asked the blacksmith to describe the woman's appearance and found that it was the same as the female master...... It's very similar. Ye Muchen glanced at him, "It's just similar?" ”

"In order to be more accurate, my subordinates asked people to draw a portrait of Miss Su to show the blacksmith, but the blacksmith immediately said that the heroine was the woman."

After Beiyu finished speaking, he secretly looked at Ye Muchen with his afterglow, but he didn't see the slightest surprise on his face! It's about being happy.

Ye Muchen seemed to be super satisfied with the title of hostess that Beiyu said.

He looked at such a master, remembered the events of last night, a strange light flashed in his eyes, and after thinking about it, he took out the rolled paper from his chest and handed it to the table.

Ye Muchen glanced at it.

Drawing?

Beiyu replied, "This is the blueprint of the mistress to build this boomerang for the blacksmith. ”

Ye Muchen's eyelids moved, he reached out and picked up the paper, and asked lightly while pulling out the ribbon on the paper: "Didn't she already get the boomerang, why is this drawing still with the blacksmith?" ”

"This boomerang is not easy to fight." Beiyu said, "Master, you can take a closer look at the drawing, this kind of boomerang looks almost the same as an ordinary boomerang, in fact, it is not, every turnaround port, cutting point, and tip is actually a hidden mystery, and the more you look at it, the more you will feel that it is not simple." ”

"Although the blacksmith has been making iron for decades, it is said that it is the first time he has received such an elaborate boomerang list, this kind of boomerang, although the blacksmith is experienced, but he can only play one a day."

Ye Muchen didn't rush to spread out the paper after pulling off the ribbon, Wen Yan lifted his beautiful eyelids and carefully observed the boomerang, and asked, "This is the first one?" ”

"Yes." Beiyu said: "There is only such a thing in the hands of the heroine." ”

When Ye Muchen heard this, his lips curled without a trace.

It turned out that this was the first one, no wonder the girl was so nervous last night.

Beiyu didn't know what he thought, and he looked up and was about to talk to Ye Muchen, but he caught a glimpse of the corners of his slightly curled lips without commenting.

He was stunned for a moment.

Master, this is ...... Laughed?

He thought he was wrong, he couldn't help blinking his eyes, and then looked at Ye Muchen, but found that the corners of his lips really curled up a beautiful arc, although it was shallow, but the master was really smiling......

His heart was turbulent, and he secretly wondered how long he hadn't seen his master smile?

When Beiyu was staying, Ye Muchen asked, "How many fights does she need?" ”

"The hostess knows that this kind of boomerang is very difficult to fight, and she is afraid that she will not be satisfied with the blacksmith's shot, and she is afraid of losing silver, so she ordered ten first."

That girl is quite smart!

I really don't want to eat at all.

Ye Muchen thought so, his eyes were still staring at the boomerang, and asked, "That girl is satisfied with the dart made by the blacksmith when she takes the boomerang?" ”

Ah, girl?! This kind of affectionate title can actually come out of the mouth of his own master?

Beiyu was greatly taken aback by Ye Muchen's name Su Jin, although he couldn't hear anything except his tone, but this title alone was enough to shock!

Could it be that this title is only for a moment...... Say it in passing?

"Nope." Beiyu remembered the blacksmith's words and couldn't help but smile, "It is said that he is not satisfied at all. ”

"Not satisfied at all?"

"The blacksmith said that the female master was so angry when she saw the dart he played that she wanted to smash the head of the blacksmith, and scolded them for not beating the dart like that, and refused to give the blacksmith the money for this dart."

Ye Muchen's eyes flashed: "Four are not like? ”

The blacksmith said, "The shape is different, the size is different, the weight is different, and the details of the dart body are not cleverly made, resulting in a tenfold decrease in the power of the whole boomerang." ”

"Is it a tenfold drop?" Ye Muchen's eyes shattered into a deep light.

"Yes." Beiyu saw that Ye Muchen hadn't opened the drawings to look at them, and couldn't help but say: "Master, my subordinates have taken a look, in fact, this dart is exactly the same as the drawing, there is nothing wrong with it at all, I don't understand why Mrs. thinks this dart is not well made." ”

Ye Muchen listened, put down the dart in his hand, and opened the drawing.

The blueprint is lifted, and a lifelike boomerang jumps. The drawing was very wide, a small boomerang blueprint, and she used more than a meter of paper.

Still, she didn't mean to waste paper, because the space of the paper was used very thoroughly, and it was almost full of stuff.

A boomerang is drawn in the center of the drawing, and the paper is surrounded by a high degree of decomposition of each part of the boomerang, and when decomposing, not only the thickness, width, dense point, tangent point, and angle of these parts are marked, but also the force on it during the rotation is also annotated......

Looking at the annotations on the drawing, the more he looked at it, the tighter his brows tightened, and his lips pursed tightly.

Beiyu rarely saw Mu Chen's expression like this, and couldn't help but look over: "Master, is there anything wrong with this drawing?" ”

Ye Muchen: "No. ”

He was telling the truth, not only did he not find the slightest mistake in this drawing, but he discovered a lot of new things on this drawing—something they had never tried before, but it was enough to be shocked at first glance!

Beiyu listened to Ye Muchen's words, his face slightly shocked, "Can't you find a trace of error?" ”

Ye Muchen didn't answer, thought about it, re-rolled up the drawings, handed them back to Beiyu, and said while staring at the boomerang: "That blacksmith is really not good-made, and the power of this boomerang has indeed greatly decreased." ”

"Ahh Beiyu was dumbfounded,

"That ......"

"You show the drawings to our people and let them try to build a few of them. Look. ”

Beiyu took the drawings and bowed his head: "Yes!" ”

Beiyu originally wanted to run errands, but when he saw the dart on the table, he couldn't help but suggest: "Master, this dart body is red, as a hidden weapon, this color is too obvious and too public, and it is easy to be detected by the enemy when it is launched. ”

Ye Muchen didn't answer, but said, "You can ask people to try to create a few iron black ones, and compare them with crimson." ”

"Yes."
