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

Qi soldiers from the Xuanhuang world used synthesis skills to combine metal elements such as iron, manganese, and tungsten into more than a dozen alloys.

Using various self-made equipment, we tested the alloy's hardness, toughness, corrosion resistance, and recorded the relevant data.

Materials are the foundation of industry; all kinds of machinery and equipment cannot function without materials.

Some parts have specific requirements for high temperature resistance, low temperature resistance, corrosion resistance, and hardness due to their working environment.

Not just any material can be used for aircraft engines, deck steel, drill bits, and cutting tools.

Possessing the skill of decomposition and synthesis, he can synthesize various materials at will.

If the synthesized material has excellent properties, he will then work on industrial production technology.

Around 10 p.m., Qi Bing took a shower and returned to the east courtyard to rest.

After waking up and finishing his morning exercise, Qi Bing ate breakfast and rode his bicycle to the library.

After reading all morning, my knowledge base has expanded considerably.

I had lunch at Fengzeyuan Restaurant, and then returned to the East Courtyard to focus on practicing martial arts.

"Without considering cultivation bonuses, the maximum physical strength of a level one human is approximately one thousand kilograms."

"I am an eleventh-level human. Through pure strength training, my physical strength can theoretically reach eleven thousand kilograms."

"Humans of the same rank have vastly different physical strengths depending on whether they cultivate or not."

I cleared my mind of all distractions, glanced at my watch, and saw it was almost 5 p.m.

Qi Bing entered the Xuanhuang World, prepared a meat dish and a vegetable dish, and ate a simple dinner.

"Eighty percent iron, five percent tungsten, three percent manganese..."

Make alloy samples, conduct various tests, and record various data.

By adding or removing certain metal elements, the sample is synthesized again, and the results are then tested and recorded.

Materials experiments can be tedious, and whether or not excellent materials can be developed is anyone's guess.

With a stroke of luck, excellent materials can be developed in just a few experiments.

If you're unlucky, you might spend years or even decades trying and squander countless funds, but achieve nothing.

For Qi Bing, who has mastered the skills of decomposition and synthesis, the only cost of materials experimentation is the time it takes.

The tested sample materials, through the application of decomposition techniques, instantly transform into various elements.

In a flash of inspiration, Qi Bing took out his alloy embroidered spring knife and disassembled a section of the blade, the edge, and the scabbard.

Using the synthesis skill, the Alloy Embroidered Spring Blade was restored to its original state.

Using the corresponding elements and the synthesis skill, create a sample of the same alloy as the Embroidered Spring Blade.

He was overjoyed when he saw the results of various tests.

"I never imagined that the alloy of the Embroidered Spring Blade would not only be hard and tough, but also resistant to high and low temperatures and corrosion. Its properties are even better than I thought, and stronger than the materials used in American aircraft carriers and planes."

During the previous war, Qi soldiers captured several American aircraft and disassembled and mastered American aircraft carrier technology.

Although he hasn't mastered the industrial production technology for American materials, he can use his synthesis skills to create counterfeit materials.

Record various data about the alloy of the Embroidered Spring Blade, and Qi Bing will conduct a new round of experiments based on the elemental composition of the alloy.

Increase or decrease the amount of a certain element, synthesize some samples, and then conduct experiments and record the results.

Based on the existing embroidered spring knife alloy, one or more other elements are gradually added, and then tested and recorded.

"Alloy No. 1 has high hardness, good high temperature resistance, and good toughness, making it suitable for making shafts and bearings."

"Alloy II has high hardness and good toughness, making it very suitable for making industrial cutting tools and drill bits."

"Alloy No. 3 has good strength and excellent corrosion resistance, making it suitable for making certain containers."

In just over ten days, Qi Bing developed more than 300 kinds of excellent materials based on the alloy of the Embroidered Spring Blade.

He named the alloy for the Embroidered Spring Blade "Alloy Zero". The alloys he developed afterward were named "Alloy One", "Alloy Two", "Alloy Three", "Alloy Four", "Alloy Five"... "Alloy Three Hundred and Sixty-Three".

"Including the alloys used in American aircraft carriers, I can synthesize hundreds of excellent alloys."

"Take a break for a while, and then figure out the industrial production technology for various alloys."

After soaking in the hot springs for a while and having a late-night snack, Qi Bing returned to the east courtyard and slept until he naturally woke up.

Around 7 a.m., he rode his bicycle, carrying his homemade fishing gear, to the Yongding River to fish.

There were very few entertainment options in those days, and Qi Bing, who didn't have many hobbies to begin with, would only occasionally go fishing.

Hunting? There's too little prey around Beicheng, and he doesn't want to waste time hunting since he has no cheat codes to use.

When you want to hunt, in the Southern Continent of the Xuanhuang World, you can hunt whatever you want, as much as you want.

Qi Bing found a fishing spot with a water depth of about three meters and used fermented corn and wheat to create a feeding area.

I took out my homemade titanium alloy surf rod, hooked two tender ears of corn on the hook, and cast the line casually.

The homemade titanium alloy surf rod has several settings, which can be converted into 3.6 meters, 4.5 meters, 5.4 meters, 6.3 meters, and 7.2 meters. When fully retracted, the length of the fishing rod is only 1.2 meters.

The skill of decomposition and synthesis is amazing and powerful.

Qi Bing used the decomposition and synthesis skill to create many things, such as titanium alloy surf rods and titanium alloy lighters...

Even the smallest guide on the surf rod has an inner diameter of one centimeter, making close-range fishing easy and long-range casting effortless.

After setting up the fishing rod, Qi Bing sat on the folding chair, took out a cigarette, lit it, and took a leisurely puff.

"Well-known TCM doctors from various regions serve as TCM examiners; those who are merely pretending to be qualified are no longer qualified to treat patients."

"The thermal power generators in Chongqing have achieved mass production, and in many places in Xiaguo, top and bottom blowing steelmaking furnaces are under construction."

The Qi soldiers, puffing out clouds of smoke, recalled the past and felt a great sense of accomplishment.

"Aside from going to the library to read, I spend most of my time in the East Wing or Xuanhuang World. I'll go fishing more often in the future."

More than two hours later, the fishing float went back into the water.

Qi Bing pulled the pole, and a powerful force followed.

Having grasped the principle of handling light matters with great force and light matters with lightness, he achieved an unparalleled level of control over his own strength.

Despite possessing physical strength far exceeding that of ordinary people, the strength he uses in daily life is roughly the same as that of an average person.

"This fish should weigh about 15 pounds."

Qi Bing spent more than ten minutes playing with the fish, and a large grass carp surfaced.

I caught the fish with my bare hands, removed the hook, and weighed it; it was about sixteen pounds.

"That's enough for lunch, time to pack up and go home."

After packing up, Qi Bing took his belongings and rode his bicycle back to the east courtyard.

The fish was killed with practiced ease, half sliced ​​and half chopped.

After working for more than an hour, Qi Bing finally started eating lunch.

"The sweet, sour, spicy, and numbing Tai'an fish, and the spicy and fragrant boiled fish, my cooking skills are getting better and better."

The method of making Tai'an fish is very simple: chop the fish meat into pieces, coat it with sweet potato starch, deep-fry it, and then braise it. The taste is similar to shredded pork with fish flavor. Add more Sichuan peppercorns and chili peppers, and you will taste spicy, sour, sweet and sour with a slightly crispy and fragrant flavor.

After filling their stomachs, they entered the Xuanhuang World and began practicing martial arts.

The fact that the Heavenly Dao cannot leave the Primordial World now does not mean that it will never be able to leave the Primordial World.

The Primordial World is located in the very center of the Chaotic Universe. The Lesser Thousand World, where the Courtyard World is located, is in the endless chaos outside the Primordial World. Within the Chaotic Universe, there is the Heavenly Dao, a potential enemy. Qi Bing can only strive to improve his strength.

If the human system can bring him back to life once, it can bring him back to life a second, a third, and countless times.

Perhaps in this life, or the next, or some future life, he will go to the primordial world.

Once a person gets busy, all sorts of anxieties will disappear.

After finishing his martial arts training and taking a medicinal bath, Qi Bing continued his materials experiment.

A few days later, Yang Ruihua from the front yard went into labor and was taken to the hospital by Yan Bugui.

A few hours later, Yang Ruihua gave birth to a daughter in the hospital, who was named Yan Jiedi.

The next morning, Yang Ruihua and Yan Jiedi returned to the courtyard house.
