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

Qi Bing didn't care much about the relationship between the characters in the Siheyuan storyline and the time travelers. As long as the four time travelers worked hard for the development and growth of the Great Xia Dynasty, he didn't care about anything else.

At this time, the Qi soldiers were pondering the Flying Thunder missile with a range of about 30,000 kilometers.

The metallic hydrogen mushroom does not yet have a matching missile; the existing Flying Sword series missiles have a maximum range of only 2,000 kilometers.

Qi Bing wanted to develop a missile with a range of 30,000 kilometers that carried metallic hydrogen mushrooms.

Although the diameter of Earth is only a little over 12,000 kilometers, theoretically, a missile with a range of about 13,000 kilometers could cover the entire planet, but he felt that the longer the range, the better.

A frontal attack has the highest probability of being intercepted, while missiles with longer ranges offer more flexible strike options.

The Flying Knife series of missiles are man-portable missiles.

The Flying Sword series of missiles are divided into vehicle-mounted, airborne, and shipborne types.

At this stage, Xia Kingdom needs a missile that can carry large fireworks.

The name "Flying Thunder" is chosen because it flies far and its attack is like thunder. The name "Flying Thunder" is chosen because it can carry large fireworks. This name is both fitting and a tribute to the Flying Thunder Cannon of the past.

Qi Bing, with his extensive knowledge, exceptional intelligence, and outstanding comprehension, spent several days successfully developing a vehicle-mounted flying thunder missile.

He tested the Xuanhuang World multiple times and solved all the problems he discovered.

Since the Xia Kingdom in the Siheyuan world did not yet have a satellite positioning system, the Flying Thunder missile developed by the Qi army, with inertial guidance, radio correction, and astronomical star map positioning, had a theoretical hit accuracy of about fifteen meters.

The core of inertial guidance is the gyroscope. Astronomical star map positioning is based on the position of stars and pre-installed star map, and the parameters are automatically corrected. Radio correction is to send commands to the missile using radio equipment.

Within the radio signal coverage area, the accuracy of the Flying Thunder missile will not exceed five meters.

Beyond the coverage area of ​​radio signals, the Flying Thunder missile mainly relies on star map positioning and inertial guidance, with a theoretical error of about fifteen meters.

A 15-meter error may seem like a lot, but compared to the power of a large firework, this error is negligible.

"Radio signals may be interfered with; cancel the radio correction system."

"A 15-meter error has no impact whatsoever; it's purely mechanically guided, making it safer and more reliable."

After disabling the radio correction system, Qi Bing re-optimized the Flying Thunder missile.

Based on his self-developed vehicle-mounted flying mine missile technology, he successively developed airborne flying mine missiles, silo-based flying mine missiles, shipborne flying mine missiles, and submarine-launched flying mine missiles.

"The five versions of the Flying Thunder missile, with a range of 15,000 to 32,000 kilometers, are sufficient."

After repeatedly testing various versions of the Flying Thunder missile and resolving the various problems discovered, Qi Bingzhi stopped, feeling quite pleased with himself.

Use the synthesis skill to obtain the production technology data for the Flying Thunder series missiles.

The following morning, Qi Bing handed over the production technology data of the Flying Thunder series missiles to Yucheng Industrial Group.

Yucheng Industrial Group is mainly divided into civilian industry and military industry. The level of secrecy of civilian industry is relatively low, while military industry is all top secret.

All the relevant technologies for weapons and equipment are handled by the military industry department of Chongqing Industrial Group, so there is no need to worry about leaks.

Within the Yucheng Industrial Group, materials and equipment technologies with higher technical content have been assigned to the military industry sector.

Elder Shi laughed and said, "Little Qi, our long-range missile technology has only just begun development, and you've already developed the complete technology."

Qi Bing said, "Old leader, I spent a lot of time on the Flying Thunder missile technology, and it was only recently completed."

Elder Shi was Qi Bing's former boss. Starting three years ago, Elder Shi personally took charge of the Yucheng Industrial Group.

Yucheng Industrial Group has undergone several upgrades, and last month it became a first-level unit.

The industrial groups in Beicheng, including those from Chuanzhou, Yunzhou, Guizhou, Xiangzhou, and Ezhou, are all currently at the fifth level.

Honestly, Qi Bing admits that he has a slight preference for Chongqing, which is largely due to the city's various advantages.

Chongqing has ample strategic depth, a terrain that is easy to defend and difficult to attack, and is almost free from natural disasters such as typhoons, rainstorms, and earthquakes.

In times of chaos, they would go out together to fight the enemy; in times of prosperity, they would go out together to work. Every time Qi Bing thought of this, he felt a little sad.

In a past life, I once saw a post online from someone from Haicheng who confidently asserted that people from Chuanzhou were poor because they lacked a fighting spirit...

Haifu is not rich simply because it lives by the sea, but because of the long-term preferential treatment of resources and regulations.

In Qi Bing's mind, resources and rules should be allocated according to contributions in killing enemies and providing supplies...

"Xiao Qi, since you moved here from Beicheng, the development speed of Yucheng Industrial Group has increased significantly."

"Old leader, serving the country is my duty, and it is something that all people of Great Xia should do."

After chatting for about ten minutes, Qi Bing seized the opportunity to suggest forming a supervisory group.

In his personal view, all non-classified units should be subject to public scrutiny.

Whether other places do it or not is their business; Chongqing should form a supervisory group.

"Xiao Qi, tell me in detail."

"The old leader would randomly select some people from among the workers' and peasants' families every year to be responsible for supervising non-classified units, such as supervising school meals, teaching, and the issuance of certificates and procedures."

"This is a good idea. Randomly selecting some people each year greatly reduces the chances of the supervisory team members being bribed. The supervisory team members only have the right to observe, make suggestions, and report, and it will not affect the development."

"Old leader, the matter of setting up a supervisory team in Chongqing still depends on you and Elder Long."

Around noon, after having lunch at the canteen, Qi Bing rode away on his electric scooter.

"Once the Flying Thunder series missiles are equipped by the Xia army, Xia's offensive power will be invincible on Earth in the world of courtyard houses."

The existing Splash series missiles and Flying Knife series missiles are primarily defensive in nature.

The two main functions of the Flying Thunder series of missiles are deterrence and attack.

Back at the villa, Qi Bing used his divine sense to explore all directions.

"Xiao Ze from the courtyard house is also a time traveler. When did he arrive?"

After observing Xiao Ze in secret for several days, Qi Bing was almost certain that Xiao Ze's cheat system was a lottery system.

After making a phone call to Elder Mu, Xiao Ze was transferred to the North City Industrial and Agricultural Research Institute in less than three days.

"From now on, all time travelers from the courtyard houses will be thrown into the North City Workers and Peasants Research Institute."

On Sunday morning, Qi Bing accompanied his wife and children shopping.

"Dad, I want to eat that."

"Dad will buy it for you."

"Dad, I want to eat too."

Qi Bing, who was shopping with his wife and children, would occasionally buy snacks for the two children.

Around noon, they found a restaurant and had a simple meal.

In Chongqing, there are a fair number of people who know Qi Bing.

Only Elder Shi and Elder Long knew his true background.

The employees of Yucheng Industrial Group only knew that he was a level three engineer at Yucheng Industrial Group.

Qi Bing is usually very low-key, and his license plate is also low-key, with numbers like five, six, seven, eight, and nine, which are inconspicuous.

Nowadays, the cars that attract the most attention are SUVs and sedans, while pickup trucks are everywhere.

Supervisory groups were successively established in the main urban area and various districts and counties of Chongqing. The members of each supervisory group were ordinary citizens.

During their visits to various units, the supervisory team discovered some problems and received suggestions and reports from the team, which were promptly addressed by the relevant units.

If you delay or process it too slowly, the Comprehensive Management Bureau will take action, and you'll definitely regret it then.

On a whim, Qi Bing chatted with Elder Shi and Elder Mu, and then Yu Cheng began his studies.

The four-way profit-sharing period lasted a total of ten years, and it will end next year.

Starting the learning mode early not only has many benefits, but can also avoid certain troubles.

"Everything is ready. Last time, we laid our net and reaped huge rewards. The next two times we lay our nets will surely yield even greater results."
