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

As for Qi Bing, he didn't care whether He Daqing, Jia Dongxu, and Zhang Cuihua lived or died.

With the blessing of fate and the concept of cause and effect, Qi Bing calculated that Yi Zhonghai posed no threat to him or his family, and decided to give up the idea of ​​dealing with Yi Zhonghai. He wanted to witness Yi Zhonghai being used and discarded.

The path of cultivation is like rowing against the current; if you don't advance, you fall behind. The same is true of life.

Qi Bing firmly believed that people cannot be idle; once they become idle, all sorts of problems will arise.

Many people in their sixties are healthy in body and mind when they are at work, but after retirement they have nothing to do and soon develop various diseases.

Many people in rural areas, in their sixties and seventies, work every day, are in good health, and have a positive attitude.

Qi Bing himself didn't want to be idle, and he didn't want the three time travelers to be idle either.

Lin Fan and Ye Qiu both had a heavy workload, while Li Kun's workload was relatively lighter.

After considering it for a few days, Qi Bing approached Elder Mu and suggested that Li Kun take on the task of developing plant technology.

Almost all conventional pesticides leave some residue, and even within safe limits, they can still cause some harm.

Individual agricultural products, with residues within safe limits, are consumed three times a day, and we don't just eat one type of food.

Whether the residues from multiple foods combined are still within a safe range is unknown.

Just like the additives in beverages, drinking only one bottle of beverage a day will not affect your health, but it's hard to guarantee that some people will drink several bottles of beverage a day.

"Garlic water can control aphids, fungus gnats, and spider mites; chili water can control aphids, spider mites, and scale insects; ginger water/scallion water/leek water can control cabbage caterpillars, aphids, and soft-bodied insects..."

Qi Bing, who was secretly considering things, went to Elder Mu, and subsequently Li Kun obtained a research project on using plant-based water to replace pesticides.

"There are still too few transmigrators. If we could get more, we could add some new projects."

Chemically synthesized pesticides pose varying degrees of harm.

Using light, sound waves, magnetic fields, and similar methods, agricultural pests can be killed in a non-toxic and harmless manner.

Busy with cultivating, learning, and researching element transformation technology, Qi Bing had no extra time to develop physical pest control technology.

Ye Qiu and Lin Fan's agricultural research project is related to the grain output of Xia Kingdom.

On the fifth day of the seventh lunar month, the good news of the successful production of large fireworks quietly spread in a small circle.

The ability to produce large fireworks ahead of schedule is largely due to the Chongqing Industrial Group.

Many of the equipment used to manufacture large fireworks are produced by Chongqing Industrial Group.

On the ninth day of the seventh lunar month, a deliberately muted fireworks display took place in New South Wales, and The Big Summers announced the success of the fireworks project.

Major overseas powers dispatched spies to investigate and confirmed that Xia Kingdom had indeed created the giant fireworks.

After assessing various data, the US, the Soviet Union, and other powers all breathed a sigh of relief.

The fireworks manufactured in Xia Kingdom are of mediocre quality and too weak in power, posing little threat to the United States and the Red Sands.

Even a weakened version of the Great Fireworks is still a Great Fireworks. Before and after the Great Fireworks were created, the status of the Xia Kingdom on Blue Star underwent a tremendous change.

Qi Bing, through the Comprehensive Management Bureau, handed over the metal hydrogen mushroom version of the large fireworks technology to Yucheng Industrial Group.

Metallic hydrogen mushroom-type fireworks are non-toxic, harmless, pollution-free, and radiation-free, making them the most ideal technology for large fireworks.

The metallic hydrogen mushroom-shaped fireworks can blast mountains and reservoirs on a small scale, or destroy enemy cities on a large scale.

Li Kun's project to replace pesticides with plant-based water is quickly getting on track.

Twenty acres of land next to the No. 1 steel rolling mill were allocated to Li Kun for his experiments.

The effects of the first-generation pepper spray gradually became apparent; vegetables sprayed with pepper spray were free of insects.

The twenty acres of land allocated to Li Kun for his experiments were already planted with a lot of vegetables.

With the help of the technologies or skills obtained from the treasure chests, Li Kun's research and development projects are progressing smoothly.

The three time travelers in the courtyard began to share their technological knowledge and help each other.

Some of the techniques Li Kun obtained from the treasure chest were of little use to him, but Ye Qiu or Lin Fan could use them.

Some of Ye Qiu's or Lin Fan's techniques are of great use to Li Kun.

The Qi soldiers, who were secretly observing everything, were very pleased to see the three time travelers cooperating.

The three transmigrators posed no threat to him or his family. Moreover, they were doing things for the country and its people, so he had no reason to and would not deal with them, at least not now.

The past is history, the present is unfolding, and no one knows what the future holds.

Even though his calculation ability was superb, Qi Bing knew in his heart that the future he predicted could not remain unchanged.

Including him, there are now five known transmigrators in the Siheyuan world.

Not counting Jiang Fan who died, there were already four transmigrators in the courtyard alone.

The addition of another time traveler will bring about some changes to this courtyard world.

Whether there will be any more time travelers in the courtyard in the future, nobody knows.

......

Intermediate Court, He Family.

Liu Yuhua asked, "Brother Zhu, Ma Hua has been your apprentice for over a year, and you haven't taught him a single thing?"

He Yuzhu defended himself, saying, "Wife, it's not that I don't want to teach him cooking skills, it's just that his basic skills are too poor."

Liu Yuhua advised, "Brother Zhu, times have changed, and your status is different now. You are now the canteen director. If you, as the director, personally cook for ordinary banquets, people will definitely laugh at you for teaching your apprentices to keep things to yourself."

He Yuzhu was stunned for a moment, thought about it again and again, and felt that his wife was right.

If you don't teach your apprentices any real skills, you'll be criticized sooner or later. If your apprentices have no skills, you'll have to cook all the meals for the factory in the future, which is inappropriate no matter how you look at it.

He Yuzhu said, "Wife, I'll listen to you. Tomorrow I'll teach Ma Hua some real skills."

Liu Yuhua added, "Brother Zhu, that fat guy in your cafeteria doesn't look like a good person. You should be careful."

He Yuzhu nodded; "Yes, I only need one disciple, Ma Hua. Ma Hua is honest and upright, while Fatty is too calculating."

Ma Hua has been working at the factory for over two years and has been He Yuzhu's apprentice for over a year.

The fat man had just joined the factory and had always wanted to become He Yuzhu's apprentice, but he was not yet He Yuzhu's apprentice.

That evening, I accompanied my wife in practicing the Heaven and Earth Profound Yellow Technique, and Qi Bing entered the Profound Yellow World.

Qi Bing's eyes lit up when he saw Qin Jingru and You Fengxia dressed in professional attire.

With the help of the Heaven and Earth Profound Yellow Technique, Qin Jingru and You Fengxia continued to improve their cultivation.

More than two hours later, the Qi army once again explored Beiju Luzhou.

The four continents and four seas of the Xuanhuang world are not only vast in area, but also rich in species.

He found more than 3,000 varieties of tea trees alone.

Qi Bing discovered more than 300 varieties of tea trees that are over 10,000 years old.

Today, in Huaguo Mountain of Dongsheng Shenzhou, there are more than 300 tea trees that are over 10,000 years old and more than 5,000 tea trees that are over 1,000 years old.

Although the environments of Xiniu Hezhou and Beiju Luzhou are harsh, the concentration of spiritual energy in Xiniu Hezhou and Beiju Luzhou is not much less than that in Dongsheng Shenzhou. Although the number of natural treasures is far less than that in Dongsheng Shenzhou, there are still quite a few.

Qi Bing moved the Xuanhuang Manor, the Human Path Xuanhuang Pagoda, and the industrial base from the Southern Continent to Huaguo Mountain.

Around 2 a.m., Qi Bing returned to the east wing outside.

I took a nap and ate breakfast made by my wife, Liu Xiaoqian.

Liu Yongfeng asked, "Xiao Qi, shall we go fishing?"

With school on summer vacation, Liu Yongfeng, Chen Xiaoya, and Liu Xiaoqian began to rest again.

Qi Bing agreed and drove his family to the river to go fishing.

After net fishing was banned in natural waters, the number of fish, shrimp, and crabs in the river increased significantly.

Reservoirs and ponds built to combat drought are used for raising fish, shrimp, and crabs.

Many reservoirs or ponds used for raising fish, shrimp, and crabs have not only been equipped with oxygenators, but also with water intake and drainage systems.

It's mid-July now, and the weather in the northern part of the city is perfect for fishing.

Qi Bing enjoys fishing, and while fishing, he can also spend time with his family, truly killing two birds with one stone.

Fishing combined with a picnic is undoubtedly a delightful experience.
