Zhao Xie said: "There is Lao Qing's family, Zhao Guo needs a crossbow to resist the attack of the Xiongnu and Han army, and the method of this production needs to be kept secret and not leaked." ”

The repeater crossbow is large in size, and is not suitable for offensive warfare and sports warfare, but is suitable for defensive warfare, ambush warfare, and blocking warfare where the soldiers are in a fixed position.

Speaking of this, Huang Tingjing's expression became serious, and he said: "The king, the ministers can try their best to study and make weapons, and I hope that the king will invade other countries less and kill less in the future, and it is the people who suffer from war!" ”

Zhao Xie said: "The widow also doesn't like war, but many wars can't be avoided. For example, Liu Bang invaded other countries, who can convince Liu Bang not to invade! In the face of such people, Zhao Guo can only actively prepare for war, rise up to resist, and defend the homeland with one heart. ”

Huang Tingjing was disgusted with Liu Bang, agreed with the king's statement, and said again: "The king, in addition to needing weapons to defend the country, the minister also hopes to improve farm tools so that the people can farm better. Some of the ink scholars specialized in irrigation and farming tools, and the minister invented a water-inducing irrigation tool powered by water flow, and then drew it and presented it to the king after returning to the Zhaoxian Pavilion; There are also people who make improvements to the existing 'Rakwan', and when they come to Xiangguo, they will definitely be presented to the king. ”

The Mohists were concerned with the working class at large, and were more interested in the study of agricultural and handicraft tools than in military equipment.

Zhao Xie smiled, and took three more pre-drawn drawings from the bookshelf.

Huang Tingjing took a look, and his eyes instantly lit up.

The first drawing depicts a "keel car", also known as a "rollover". This is a scraper-type continuous water lifting machine, the planks with water are connected or looped with wooden tenons to draw water, which can be driven by hand, foot, ox turn, water or wind, generally set up by the river or pond, and take water for land irrigation.

The second painting depicts a waterwheel, which is annotated as "Water Drum Cart" and explains the corresponding principle. Lay a hard pile on the shore first, make a big wheel, rest the shaft of the big wheel on the pile fork, when the big wheel water board is excited by the water flow, drive the wheel to rotate, the water cylinder is filled with water, turn the top of the wheel, the cylinder mouth is tilted downward, the water just pours into the trough, and flows along the trough to the field. This kind of cylinder car can be watered day and night without stopping to water the ground, without the power of people and animals.

In ancient times, the country was founded on agriculture and attached great importance to agricultural irrigation and water conservancy facilities.

At the end of the Shang Dynasty, humans invented the orange tree (a simple water extraction machine using the lever principle) and the bucket. After the keel car was invented, with the continuous progress of mechanical technology and continuous improvement in the axle, the simple car was invented.

In the original history, the keel car appeared in the Eastern Han Dynasty, and the simple car appeared in the Tang Dynasty.

The drawings in the third chapter depict a plough, annotated as "Curved Plough".

During this period, oxen ploughing tools were iron mouth plows. This kind of plough is a straight plough tip, the upper part wears a horizontal wood as a handrail, the lower part is inserted into the bottom of the plough and wears a wooden board to block the mud, and one end of the plough bottom is equipped with a triangular pointed iron, which belongs to a kind of straight plough.

When ploughing the land with a straight plough, turning back is not flexible enough, the soil is laborious, the historical Quyuan plough was invented in the Tang Dynasty, and the Zhao Xie drawings painted belong to the plough in the Song Dynasty, which is improved and perfected on the basis of the Quyuan plough in the Tang Dynasty, so that the plough is shortened, curved, reduced in the amount of strategy, pressing and other components, the plough body structure is more lightweight, flexible to use, and the tillage efficiency is also higher.

Looking at these three drawings, Huang Tingjing couldn't calm down for a long time.

The irrigation tool he just said to King Zhao that he invented was the keel car in the drawings, but it was only a rough prototype and needed to be perfected before it could be put into use; The keel car drawn in the drawings is more complete in structure than what he invented, and as long as it can be manufactured according to the instructions, it can be put into use.

For the Quyuan plough and the simple car, in his eyes, it is even more ingenious.

"Huang Aiqing, the Mo family cares about the suffering of the people, and the same is true for the widows, making these three tools to improve production efficiency and let the people farm better, isn't it in line with the Mohist ideology! The widow hopes to get the help of the entire Mo family, just to better benefit the people! ”

Huang Tingjing was so excited that he knelt down to Zhao Xie.

"I'm Wang Yingming! Blessed are the people of the world! ”

After speaking, he kowtowed to Zhao Xie again, which was the first time he knelt down and kowtowed to someone. The king of Zhao in front of him can not only care about the people, but also have inventions and creations and tax policies that are really beneficial to the people, and he is willing to kneel for such a king.

Juzi is completely subdued, this is exactly what Zhao Xie wants to see, and today is a major success.

"Aiqing invites you to stay in Zhao to serve, which is to benefit the people."

After Huang Tingjing stood up, Zhao Xie said again: "The widow has decided to set up a new department, named the 'Technology Department', with the same status as the five departments, specializing in science and technology, and you are the secretary of the Technology Department." ”

The Mojia Juzi is relatively well-known in this time and space, and represents the entire Mo family, and it is not inappropriate to give Shangshu the position at the beginning, which is not inappropriate because of practical needs.

However, the official position is available, and the official rank can only be the minimum configuration of the position of Shangshu - from the third grade, and gradually improve after the actual merit in the future, and the knighthood can also be given to ensure that there is enough room for promotion.

As for the establishment of the Ministry of Technology, Zhao Xie had this idea early on: Population, science and technology are the most important productive forces, and it is necessary to vigorously develop science and technology, including military science and technology and various civilian science and technology, to promote the development of productive forces.

Huang Tingjing respectfully accepted the official position, said that he would go all out, and said again that what he was good at was mechanical construction, and there were people in the Mo family who studied iron-making technology, and he would be notified to come as soon as possible.

He then specifically stated what the main characters of the Mo family were, and their respective areas of expertise, so that Zhao Xie could arrange suitable positions as appropriate.

The two disciples, Gongsun Pili and Gan Li, both have certain achievements and can also be awarded certain official positions.

Shusun Tong served as a squire, but after he returned to the Zhaoxian Pavilion, those Confucian scholars became even more vigorous in front of the ink scholars.

The officials of the Ministry sent Huang Tingjing back to the Zhaoxian Pavilion, his official position was higher than that of Shusun Tong, and finally made the Mo family raise their eyebrows, and Gongsun Pili and Ganli were very happy.

The next day, Zhao Xie officially issued an edict at the court meeting, announcing the relevant decision. This includes the appointment of Sun Shutong and Huang Tingjing, as well as the formation of a technical department.

After the Mojia has corresponding people who are good at smelting technology come to Zhao Guo to take office, Zhao Xie will appropriately provide various smelting technology principles such as steel frying technology according to the actual situation, so as to comprehensively improve the technical level.

Of course, some techniques must be kept strictly secret to ensure Zhao's technological superiority over other opponents.

No matter which school of thought people are, in terms of personnel appointment and evaluation, they will be treated equally, even if they are Mo and Confucian, they will be of great use and small talents, if they do not have the corresponding talents, they can be ordinary officials as appropriate, and if they are not competent, they will still be cleared out.

Through Huang Tingjing and Sun Shutong, Mo and Confucian scholars rushed to Xiangguo one after another, sending talents to Zhao State, and Zhao State was renewed, showing a new atmosphere.
