This is the skill of these scribes.

Obviously, they didn't take it seriously, put the unimportant documents in an insignificant position, and picked them all when the emperor asked. On the contrary, it was like the emperor was too busy to worry about. They brought them in a word.

But it was really impossible to investigate this matter in the current rules of the imperial court. Even Liu Che, who was not very good tempered, just took a breath of luck, waved to the little yellow door in front of him and asked people to move the dusty boxes that were almost sealed to the small hall where he discussed politics.

"Da Da."

With the landing of this heavy box, Gu Zheng's achievements for nearly half a year were finally displayed in front of Liu Che.

As the Yellow gates at the bottom unfolded these drawings one by one, Liu Che, sitting at the top, turned from carelessness to solemnity.

After reading the three types of structural drawings of bows and crossbows painted above, the gullied emperor quickly waved to those who started to roll up these bamboo slips, silk and silk as they were.

He was really relieved when the last bamboo tube was tied neatly.

With a little seriousness, he issued a tight sealing order to all the people in this hall.

Then he winked at Zhang Qian. Liu Che was temporarily relieved until the box was stored in the secret treasury of the imperial court.

"Like you, these boxes still need to be guarded by two people. Now go to recruit relevant personnel such as the University supervisor and master Gu into the palace. I want to have an interview with them."

"Here!"

The leader quickly stepped down and sat in the hearts of Zhang Qian and others who Liu Che started, but they rolled up in a rough sea.

They have excitement, uneasiness, and unspeakable excitement and tension.

Because with the explanation of several drawings handed down by Gu Zheng, they can see through the rough drawings that the advanced nature of these weapons and the importance of them after they are made to defend the cavalry troop.

This is a weapon of epoch-making significance, and it is also a weapon that can control the battle situation of an encounter.

However, all courtiers who have the heart of a strong man are not excited after seeing these weapons?

……

The time passed in a slightly anxious wait. When the simple and honest man with his head down and face was brought to the palace, everyone could not wait for a sound.

"Gu Aiqing, how sure are you to finish what you presented?"

At this time, Liu Che couldn't care about the majesty of the emperor. He leaned over the table in order to make himself closer to Gu Zheng.

The man at the bottom didn't disappoint him. A well-behaved "ten" suddenly settled Liu Che's heart.

"That's good! Gu Aiqing, you are really a hero of the imperial court. You just don't know how long it takes to forge these weapons and how much silver it costs?"

Hearing Liu Che's inquiry, Gu Zheng also understood it for a second. He bowed his head and thought for a moment. According to the exchange rate at this time, he compared a figure of five, but the data he gave about the time of weapon production was blurred by three points.

"If you only make one sample, you probably need the cost described by Weichen."

"However, if the government-run workshops start together and produce various parts in batches, it will be at least half the cost."

"And the time will be shortened to the minimum loss."

"At the end of the process, a familiar craftsman will produce enough standard weapons for thousands of people in about ten days."

"Oh?" Liu Che, who heard the production efficiency, was surprised. With Gu Zheng's words, he went on to ask, "isn't this made of new materials? How can it be more out of work than the weapons forged with old Carburized Materials?"

Hearing this, Gu Zheng smiled and handed over the second forging technique of steel pouring method prepared this morning.

"Your Majesty, this is the weapon steel pouring method just developed by Weichen."

"If we follow Wei Chen's method, as long as we pour new materials on the original standard blade, we can not only save most of the work time, but also save more money for the imperial court."

"Old weapons do not need to be completely eliminated. They can continue to be used only by deep processing on the original basis."

"This casting process will be more in line with the current situation of the imperial court and save your majesty more trouble."

What trouble? All departments' wrangling over military spending overruns.

According to Gu Zheng, if this new skill is combined with old weapons, even the conservative peace loving faction can't say anything against it.

Hearing this, Liu Che was overjoyed, but sitting at the top of the table, he held his happy heart and continued to ask seriously.

"Well, Gu Aiqing, if I want to see the samples of several weapons on this drawing, I need to wait a few days to finish it?"

It's a mule or a horse that always needs to be pulled out. You can't just look at the cow... It turns into bean curd residue as soon as you start, can't you?

Gu Zheng, who stood at the beginning, seemed to know what Liu Che wanted to ask. He arched his hand and answered the emperor's inquiry again.

"Your Majesty, it took me ten and a half years to design the drawings and forging processes of these weapons, and another ten and a half years to forge, melt and assemble all parts."

"Now, behind the minister, there are samples of various weapons that came into the palace with the minister."

"It's breaking the rule that weapons are forbidden in the palace. When Weichen brought them into the palace, they were transported in by dismantling them into parts."

"If your majesty is interested and you are not talented, you can assemble it on site. When the finished product is synthesized, please check it yourself."

Hearing Gu Zheng's reply, Liu Che was really relieved.

He laughed happily and approved Gu Zheng's request for on-site assembly with a wave of his hand.

"What are you waiting for? Come on, Aiqing, let's all come and see how the enemy killing weapon of the Han Dynasty was completed."

After hearing this, his confidants who had been sitting on both sides of Liu Che ran fast, one by two... Surrounded Gu Zheng and the big box behind him.

To say that this little craftsman was also really brave. Under the gaze of a group of young and promising courtiers, he still lined up the parts on the weapon one by one without blushing, beating his heart and shaking his hands, and began to combine the same.

Pang Jianzao was not idle. Following Gu Zheng's instructions, he laid hands for him one by one and handed over the parts.

Such skillful cooperation is a tacit understanding that can only be run in after countless times on weekdays.

The people around looked at the palms of the two people flying up and down. While marveling at the precision of these weapons, they also sincerely admired the craftsmanship of these craftsmen they had never known.

It's hard to say whether an expert can make such a wonderful thing if he is in the other party's position.

Because of the performance of Gu Zheng and Pang Jianzao, the people in this room took back the slightest contempt at the beginning and really treated each other on an equal footing.

"Click"

The people were still immersed in this uncanny assembly. The last part of Gu Zheng's hand was perfectly combined with the bow and crossbow on his arm.

This is a cavalry crossbow, which is more exquisite than the current bow and crossbow system, with three circles.

It has changed from a two handed crossbow to a crossbow that can be fired with one arm.

In contrast, it is self-evident who is more suitable to operate on horseback.

I don't know the power of this crossbow, and what is the maximum range of external launch.

As if he saw Liu Che's question, Gu Zheng took out a bag of crossbows and arrows that had not been opened from the edge of the box again, put them in front of Liu Che and saluted: "fortunately, the cavalry crossbow has been assembled. Please choose the test target location to test the power of the crossbow."

"Well, this should be the case. If you don't follow me to the backyard, let me try the power of this crossbow myself."

The big leaders spoke. What opinions can we have? One or two said yes one after another. Seeing the emperor's majesty snatch the bow and crossbow in Gu Zheng's hand, he ran in the direction of the back garden. Everyone can only follow behind with his robes.
