Pursued by the Heavenly Dao, first level up in the courtyard.

Reading, practicing martial arts, honing skills, and occasionally going fishing became the daily routine of Qi Bing.

Since Jia Dongxu was still alive, Zhang Cuihua didn't dare to act recklessly. At most, she could take advantage of the situation and try to gain some benefits.

Why make a scene even when it's unreasonable? Why summon Lao Jia at the drop of a hat? Does Jia Dongxu have no dignity left?

Nowadays, the courtyard houses are generally harmonious, and there are very few trivial disputes.

Bang Geng was only born not long ago, and the Jia family's house is enough for now.

Qin Huairu and Jia Dongxu wanted to buy one or two houses, but they didn't have the money.

Zhang Cuihua had money, but she was unwilling to spend it, and the plan to buy a house fell through.

In the mountain villa of the Xuanhuang World, Qi Bing looked at the rows of airplanes and fell into deep thought once again.

"It would be great if certain bolts, nuts, chains, and the like on different aircraft could be interchanged."

The industry in Xia Kingdom is in its initial stage. The similar equipment in factories in various places comes from overseas. The corresponding parts of many similar equipment have different standards and cannot be interchanged.

I recall a video I saw in a past life where someone's car fell into a ditch, and when the tow truck arrived, they discovered that the bolts didn't fit.

If the bolt holes are the same size, the bolts carried by the trailer can be used for various brands and models of vehicles.

Qi Bing's thoughts became clearer and clearer, and he decided to suggest to his superiors that a universal standard be formulated.

Bolts, belts, nuts, chains, shafts, bearings, and other parts, if they meet general requirements, can be made into corresponding general-purpose parts.

Some factories use the excuse of user safety to specially manufacture irregularly shaped parts to prevent users from disassembling them.

Specifying the diameters of various screws, thread pitches, bearing dimensions, and chain dimensions not only saves costs but also facilitates the industrialization of Xia Kingdom. It also makes the repair of most machinery and equipment faster and more convenient.

The parts are not replaceable, and if there are no readily available parts, they must be specially made for repairs.

"If the standards are unified, parts can be mass-produced. When most machines and equipment malfunction, there are replacement parts available, so there is no need for temporary processing. This will save both materials and time."

On a sudden thought, Qi Bing realized that parts of the same size might have different materials, resulting in differences in their lifespan.

"Universal sizes and material classifications are crucial for Xia Guo, which is currently extremely poor. Establishing universal standards and parts classifications ahead of time will bring numerous benefits, both overt and covert, and their impact will be immeasurable."

"Parts that are prone to breakage or frequently disassembled must be designed to be easy to remove. In the past, replacing a headlight on some cars required disassembling most of the car, wasting manpower and time."

Qi Bing, recalling his memories of his past life, would occasionally pick up a pen and write down some words.

"Many parts from overseas use imperial units, while Xia uses metric units. Dimensions are expressed in meters, decimeters, centimeters, millimeters, etc. For example, four-point pipes and six-point pipes are sizes that ordinary people don't even know."

Drawing on the dimensions of parts from American aircraft, automobiles, aircraft carriers, and equipment on the East Island, Qi Bing compiled general standards for parts.

All parts that meet the general requirements should be made into general-purpose parts. This may be a little troublesome in the early stages, but the benefits will be huge in the later stages.

To put it simply, some parts of the bicycles produced by the four bicycle factories in Xia Country are not interchangeable.

If bicycle parts from different brands are interchangeable, repairs become simple and quick.

Similar to bicycles, if the corresponding parts of similar machines in a factory can be interchanged, maintenance will be more time-saving and labor-saving.

It is obviously impractical to make the same part in only one size. Making the same part in multiple standard sizes is beneficial for repairing the machinery and equipment produced in Xia Country. In the future, when developing new equipment, there will also be common standard parts.

Because the Star Alliance, led by the United States, has banned the sale of various machines and equipment to China, it will be difficult to import equipment using imperial parts from overseas for a long time to come, and spare parts will also be hard to buy.

Qi Bing spent several days writing a proposal.

The next morning around 8 a.m., Qi Bing took his written proposal to the headquarters and met with some elders.

"We should indeed have our own standards."

"Using interchangeable parts is more beneficial than harmful now, and will be beneficial in the future."

"The machinery and equipment in Chisha also use metric dimensions. With a few modifications, we can establish the Daxia standard."

After chatting with the elders for more than half an hour, Qi Bing rode away on his bicycle.

After reading for more than two hours in the library, he returned to the East Wing and entered the Xuanhuang world.

After quickly finishing lunch and resting for about ten minutes, Qi Bing began practicing martial arts.

He practiced Dragon Roar Iron Shirt, Tiger Roar Golden Bell Cover, and Xingyi Five Elements Fist. Wearing a weighted suit weighing three thousand kilograms, he ran in the training ground, sweating profusely. Even when he was exhausted, he did not stop.

Around 5 p.m., Qi Bing stopped exercising, took a medicinal bath, and then took a hot shower.

After dinner, he continued to ponder the integrated coal chemical plant.

Once the coal chemical plant is completed, Xia Kingdom's energy and materials problems will be easily solved.

With Xia's coal resources, there is enough to last for many years.

Coal can be converted into many kinds of materials, and theoretically, plants can too.

In the process of continuing to delve into coal chemical technology, we may be able to master the technology of making various materials from plants.

"This year, we have developed a top-and-bottom blown steelmaking furnace and a thermal power generator, and upgraded and modified some machinery and equipment. In the short term, it is not advisable to build a coal chemical plant in Xia Kingdom. In our spare time, we will develop the guerrilla cannon."

Setting aside distracting thoughts, Qi Bing used various materials to create a miniature coal chemical plant.

Using decomposition and synthesis techniques, a miniature coal chemical plant was born in an instant.

The elemental composition of Jinzhou coal includes carbon, hydrogen, oxygen, nitrogen, sulfur, phosphorus, fluorine, chlorine, arsenic, and mercury.

Qi Bing's coal chemical plant uses coal as raw material and can produce eighteen kinds of materials.

The machinery was turned on, Jinzhou coal was fed in, and the first round of field tests was conducted.

"Some components in coal cannot be fully converted into materials."

After shutting down the coal chemical plant, Qi Bing used his decomposition and synthesis skills to restore the materials, emissions, and residues back into Jinzhou coal. After pondering for more than ten minutes, Qi Bing began to transform the coal chemical plant.

He used physical and chemical methods in the process of converting Jinzhou coal into materials.

As time went by, Qi Bing's coal chemical plant produced less and less residue and emissions.

He goes to the library to read books every morning, practices martial arts in the Xuanhuang World in the afternoon, and studies technology and conducts some experiments in the evening.

Occasionally I search for the Southern Continent of the Xuanhuang World, and occasionally I go fishing by the river.

"I found iron ore, copper ore, gold ore, lithium ore, silver ore, manganese ore, tungsten ore, coal ore, oil, aluminum ore, nickel ore... chromium ore in Jambudvipa, but I didn't find uranium ore."

"With my current knowledge and skills in decomposition and synthesis, if I can find uranium ore, I can create a giant firework in no time."

Knowing the principles behind large fireworks, and having the necessary materials, making large fireworks is a piece of cake using the decomposition and synthesis skills.

The reason why many overseas forces cannot produce large-scale fireworks is not because they lack the technology, but because they lack the capacity to manufacture them.

The process of refining the raw materials for large fireworks alone has deterred many forces from pursuing this goal.

Using decomposition techniques for purification, absolute purity can be easily achieved.

Using the synthesis skill, various elements can be fused together in the blink of an eye.

On October 15th, Qibing's newly optimized coal chemical plant achieved zero residue and zero emissions.

"Using Jinzhou coal as raw material, the coal chemical plant can achieve zero residue and zero emissions. If other coal is used, there may be residue and emissions, but the proportion of residue and emissions will definitely be negligible."

The coal chemical plant technology is already usable, but fearing that Chi Sha might obtain it, Qi Bing temporarily abandoned the plan to build a factory in Xia.
