However, Shen Ning did not expect that Gu Qingze had no interest in the improved version of the ten crossbows.

She lowered her head and thought for a while, then suddenly raised her eyes and said, "I still know that there is a kind of crossbow drawing, which can launch 50 arrows at the same time. It's a pity that the drawing I remember is incomplete, and the specific production method has been lost."

"Five Fifty crossbows? "

This time, Gu Qingze was really shocked. He widened his eyes in disbelief and looked at Shen Ning for a moment.

"Is there such a magic forging skill in this world? I don't believe it. Draw it quickly and show it to me. " He urged impatiently.

Shen Ning, for the first time since she knew him, saw him so restless.

"But master, that drawing is incomplete. Even if I draw it, I can't make it." She deliberately showed her helpless expression.

Gu Qingze glared at her: "I let you paint, you paint, you can't make it, can't you be a teacher?"

He could not hide the excitement in his voice. His hands pressed on the chair were even hotter in their palms and eager in their eyes.

Fifty crossbows! This is fifty crossbows!

Ha ha, if he could make fifty crossbows, he would trample that man under his feet and let him look up to himself forever!

The thought alone made him feel indescribable.

"Well, I'll draw it now."

Shen Ning pursed the corners of her lips, picked up the charcoal again and began to draw drawings.

Although the method of making the 50 crossbow invented by Ma Jun has been lost for a long time, she still remembers some incomplete drawings and draws them meticulously according to the figures in her memory.

Gu Qingze took over the drawing, his face became solemn, he frowned and looked very carefully.

Shen Ning held her breath and did not dare to disturb his thoughts.

Because there are so many missing drawings in this drawing, many key parts have no examples. It is extremely difficult to restore the fifty crossbows from these incomplete drawings.

The ten arrows of Zhuge crossbow are too heavy and clumsy to be used by a single soldier. These fifty crossbows are five times more than Zhuge crossbow. The weight and volume of this arrow box will also be increased by five times. If one wants to launch 50 arrows at the same time, it is just like a dream of heaven and night. It is impossible to accomplish anything at all.

Gu Qingze soon realized this, so his brow became more and more tight, which was a difficult problem that he could not solve at all.

Even if he can make fifty crossbows according to this incomplete drawing, it will become like the crossbow of Zhuge, which is flashy and can't be used!

This makes the pursuit of perfection absolutely intolerable.

"Fifty arrows weigh 20 jin. Even if all the shafts are made of the lightest materials, the arrows must be made of iron. If it is the lightest thin blade type, an arrow must weigh at least 62 Liang, which can no longer reduce the weight. If you add the weight of the arrow case In any case, one can't use it. He must find another way to reduce the weight of the arrow... "

As he pondered, he murmured to himself.

He raised his head and looked at the roof of the house. He thought of every way in his mind, but another one was rejected by him.

"No, this method is not good, I think again, maybe this will work? No, still not. "

Shen Ning listens silently and knows that he is baffled by the weight of the arrow.
