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

On the 25th day of the twelfth lunar month, six destroyers produced by the Yucheng Shipyard were completed.

The six destroyers are identical, each with a full-load displacement of 15,000 tons.

The destroyer was developed by Qi Bing by drawing on overseas technology from the Siheyuan (a traditional Chinese courtyard house) and referring to videos he had seen in his previous life.

The destroyer is equipped with shipborne versions of the Flying Sword series missiles and a nine-barreled Vulcan close-in weapon system...

In theory, a destroyer can take on an entire carrier fleet single-handedly, with a success rate exceeding 99%.

The Flying Sword anti-aircraft missile is for air defense, the Flying Sword anti-ship missile is for ground and ship attack, and the anti-ship and anti-submarine missile is used to deal with submarines.

The nine-barreled close-in weapon system Vulcan cannon is capable of striking enemy ships, enemy aircraft, and missiles; using it to attack pirate ships would be a waste of its potential.

Qi Bing meticulously developed the nine-barreled close-in weapon system, which is fully automatic and theoretically can fire 18,000 30mm shells per minute.

For weapons and equipment, the two biggest principles for Qi soldiers are defensive power and offensive power.

Even with the same armor thickness, the equipment produced by Chongqing Industrial Group has at least three times the defensive capabilities of its overseas counterparts.

For example, tank armor is five centimeters thick, and the Tiger tank produced by Chongqing Industrial Group has at least three times the armor thickness of overseas tanks of the same thickness.

Qi Bing spent a great deal of time and energy developing various materials.

Using his synthesis skills, he could easily create materials. The new materials had some excellent parameters, so he began to work on industrial production techniques.

Over the years, Qi Bing has developed more than 30,000 kinds of excellent materials.

Some materials have excellent performance in one parameter but mediocre performance in others; some materials have excellent performance in multiple parameters...

Under normal circumstances, not counting research and development time, it takes at least several hours, or even dozens of hours, to manufacture a material in a laboratory.

Qi Bing can create materials in the blink of an eye using his synthesis skills. The most time-consuming part of his material research is solving the problem of industrial production of the materials.

With abundant knowledge and exceptional intelligence, Qi Bing mastered the industrial production technology of materials, and the average time required for this task continued to decrease.

In the early days of the Xuanhuang world, it took a considerable amount of time to produce a material industrially.

Later, Qi Bing developed some automated production lines. By adding raw materials and setting the corresponding parameters, materials could be produced automatically.

Without automated production lines, even with another ten years, it would be impossible to industrialize the production of more than 30,000 kinds of materials.

The material samples are manufactured using synthetic techniques, and once the test parameters meet the requirements, they are tested using an automated production line.

One automated production line is not enough? With no shortage of materials, he can easily manufacture thousands of automated production lines.

Set parameters such as temperature, element ratio, and time, and then conduct the corresponding tests after the material is produced.

In the alloy production process, a difference of one or several degrees between quenching and tempering temperatures will result in differences in parameters such as hardness and elasticity.

Materials created using synthesis skills, with known proportions of various elements, can be industrialized simply by controlling the temperature and time.

Multiple fully automated production lines were tested simultaneously, with temperature and time gradually increased, making industrial production quick and convenient.

Even before the six destroyers were completed, the carefully selected officers and soldiers began studying theoretical knowledge.

Now that the six destroyers are completed, the officers and soldiers who participated in the theoretical training in advance will soon be able to become familiar with the operation of the destroyers.

As winter turned to spring, the Siheyuan Film and Television World entered 1962.

On the thirteenth day of the first lunar month, the six submarines were completed, and the officers and soldiers who had participated in the training in advance took over the six submarines.

Qi Bing, with his extraordinary strength, had no interest in military power.

With his own strength, he could sweep across the entire planet; having a comprehensive administration bureau under his control was more than enough.

The Xia Kingdom was truly remarkable, repeatedly demonstrating how to contend without contending and how to act without acting.

On the 18th day of the first lunar month, the controlled reactor power plant in Chongqing was put into operation.

On the 21st day of the first lunar month, the Chongqing Shipyard began production of reactor-powered submarines and reactor-powered destroyers.

The controlled reactor technology was too advanced, so the controlled reactor power plant was assigned to the Comprehensive Management Bureau.

On the first day of the second lunar month, the Chongqing Aircraft Factory produced thirty fighter jet prototypes.

The Raptor multi-role fighter jet has various parameters that are about 30% stronger than the US Phantom fighter jet.

The Xuanhuang World has more advanced fighter jets, and Qi Bing has the ability to develop even more advanced fighter jets. However, for the Xia Kingdom at this stage, the Flying Dragon helicopter and the Mighty Dragon multi-purpose fighter jet are sufficient. For the time being, it only needs to increase transport aircraft, bombers, reconnaissance aircraft, and passenger planes.

After a trip to Chongqing, Qi Bing handed over the relevant technologies for transport aircraft, bombers, reconnaissance aircraft, and passenger aircraft to Chongqing Industrial Group.

He had already developed these aircraft, and finished products existed in the Xuanhuang World, with more than one version for each.

......

"Congratulations, host, on arriving at the courtyard house. You have officially activated the Heaven-Defying Comprehension System. You have obtained three back rooms in the backyard, a letter of introduction for employment at the Second Steel Rolling Mill, a master-level Bajiquan, a storage space, and 500 Xia Yuan."

As Lin Fan arrived at the entrance of the courtyard house, he was excited and thrilled, but his feelings were also somewhat complicated.

Having read many fan fiction novels about courtyard houses in his previous life, he had no desire to live in a notorious brothel.

"As a transmigrator who knows the plot and possesses an unparalleled comprehension system, I have absolutely no need to fear the beasts in the courtyard!"

Lin Fan gritted his teeth and stepped through the gate.

Goalkeeper Yang Ruihua asked, "Comrade, who are you looking for?"

Lin Fan recognized Yang Ruihua at a glance, and pretended to be calm as he took out a letter of introduction: "Hello, I am Lin Fan, this is my letter of introduction."

After glancing at the letter of introduction, Yang Ruihua said with a smile, "Comrade Lin Fan, I'm the third auntie in the courtyard. You've just arrived, and the house hasn't been cleaned yet. Do you need my help?"

"No need to trouble yourself." Lin Fan didn't want to get involved with the Yan family, so he quickly walked to the backyard.

The system gave Lin Fan three back rooms. Two of them originally belonged to the deaf old lady, and the other one was empty.

Qi Bing, sensing the energy fluctuations, used his mental power to investigate and discovered that there was another transmigrator in the courtyard, which made him smile knowingly.

"If Jiang Fan hadn't died, and counting Lin Fan who just arrived, Xia Kingdom would have had three oxen and horses."

"Observe him secretly for a period of time. If Lin Fan contributes to the country, then help him and let him contribute his abilities to the development of Xia Kingdom. If Lin Fan brings disaster to the country and the people, then send him to heaven."

Discarding distracting thoughts, Qi Bing mobilized his inner energy to temper his muscles, bones, flesh, and cells.

After countless studies, Qi Bing discovered that Qi was more suitable for body tempering.

The spirit, energy, and magical power throughout the body circulate continuously in a cycle.

Unfortunately, the courtyard world lacks spiritual energy; otherwise, he could automatically become stronger without actively cultivating.

Fortunately, all kinds of fruits on Flower Fruit Mountain contain more or less spiritual energy, so he can still eat spiritual fruits.

He transplanted some of the various fruit trees he found in Beiju Luzhou and Xiniu Hezhou and planted them in Huaguo Mountain.

He used his self-created mental power to enter dreams on the monkeys of Flower Fruit Mountain.

After being tamed by the art of dream manipulation, the monkeys of Flower Fruit Mountain became his servants.

As evening fell, the courtyard gathering began again.

Liu Haizhong smiled and said, "Everyone, welcome Lin Fan to our courtyard house."

Lin Fan wandered around the yard in the afternoon and chatted with his neighbors. Feeling uneasy, he suspected that there was a time traveler in the yard.

At this moment, Lin Fan was extremely cautious and acted just like an ordinary person.

When the applause stopped, Yan Bugui introduced the people in the courtyard to Lin Fan.

Without the unreasonable Zhang Cuihua or the aloof deaf old lady, the courtyard was relatively harmonious.

Even if Qin Huairu wanted to feign pitifulness to gain sympathy and help from her neighbors, she didn't meet the criteria.

Everyone in the courtyard knows that Qin Huairu has about three thousand yuan in her possession.

Everyone in the courtyard knows that Qin Huairu earns 27 yuan a month and her three children each receive 5 yuan a month.

Without the deaf old lady as a backer, without the henchman He Yuzhu, and without the comrade-in-arms Zhang Cuihua, Yi Zhonghai had no ability to stir up trouble.
