Start with a blacksmith shop.

Li Zhenhua replaced his head with Li Yun's, then returned home from the blacksmith's shop and went straight to Li Yun's wardrobe, where he chose a shirt that he could wear.

He didn't even spare her underwear. After going through all sorts of trouble to get Li Yun's bra on, he went to the kitchen and stuffed two apples into her breasts. That was it.

As for his pants and shoes, he couldn't find any substitutes, so he wore his own pair of skinny jeans and a pair of canvas shoes that were the same style as Li Yun's.

After all this dressing up, in his own opinion, his current appearance was exactly like Li Yun's original self, except for the significant difference in height. He was standing in front of the mirror.

"Haha, when Li Yun comes back, she'll probably be shocked!" Li Zhenhua thought to himself.

Honestly, if someone isn't very familiar with Li Yun, they might easily mistake him for someone else after seeing him dressed like this.

Now he's just waiting for Li Yun to come back. It's quite a coincidence that today happened. Little Li insisted on going to the company with Li Yun, otherwise his plan wouldn't have worked.

The more Li Zhenhua looked at his reflection in the mirror, the stronger his perverse sense of humor became.

Not long after, Li Yun quickly returned from the company with Xiao Lizi. However, when she got home and opened the door, she was completely dumbfounded.

I really don't know how to describe this scene. There's someone in my house who looks exactly like me.

Little Chestnut, whom Li Yun was holding, also looked puzzled, because she had never imagined that such a scene would appear in her little mind.

For her, it was as if there were two mothers in the house, even though the mother opposite her was rather tall.

Little Chestnut looked at her tall mother in front of her, then looked up at the mother holding her hand, her eyes filled with confusion.

"Mom, how come there are two moms?"

When Li Yun heard what Xiao Lizi said, she felt terrible. She never expected this scene to happen.

Her expression turned unusually serious, and she scooped up her legs like little chestnuts, holding them quite tightly. Her reaction was to slowly move slightly towards the door.

"Who are you? I'm warning you, my house is surrounded by bodyguards. I advise you not to do anything that could cause misunderstandings!"

Seeing Li Yun's reaction, Li Zhenhua also felt that his joke had gone a bit too far. He just wanted to make a joke and didn't intend to cause any other accidents.

He immediately pressed a button on the projector, and then his face began to change. Li Yun's image disappeared instantly, and his own image was revealed in its place.

When Li Yun saw Li Zhenhua's true face appear on the other side, she immediately relaxed, but then tensed up again.

Since the person opposite could transform into his image, he could also transform into Li Zhenhua's image. She had just seen that the person opposite had a bear on his upper body.

Thinking of this, Li Yun became nervous again. Just then, the little chestnut in her arms started to struggle. After a few struggles, it managed to break free from her arms while she was distracted.

Little Chestnut slid off Li Yun and ran very fast, immediately reaching Li Zhenhua.

"Come back! Little Chestnut, don't go there!" Of course, it was too late. By the time she shouted, Little Chestnut had already run up to Li Zhenhua.

Little Chestnut tilted her head back, looking at Li Zhenhua with a puzzled expression, and asked, "Daddy, are you Sun Wukong? Do you know seventy-two transformations? How did you turn into Mommy?"

Li Zhenhua, who was originally standing, squatted down and hugged Xiao Lizi, who was asking him questions with an innocent look on her face.

"Hehe, my sweet baby, if you can give Daddy a kiss, Daddy will tell you why!"

Little Chestnut was completely engrossed, and immediately hugged his neck and kissed him on the cheek.

Li Yun, who was still standing at the door, relaxed as she watched the interaction between the two people opposite her and heard Li Zhenhua's voice. She now knew that the person opposite her must be her husband.

Although it's unclear how Li Zhenhua was able to transform into her image, this person must be Li Zhenhua himself.

Once she understood what was going on, she immediately became somewhat annoyed. She took three steps in two and went straight to Li Zhenhua's side, and her hand reached out to touch the bulge on Li Zhenhua's upper body.

The only thing she didn't quite understand was what was going on with Li Zhenhua's upper body, but when she touched it and found that it was so hard, she understood.

The hand immediately shifted its position, moving from Li Zhenhua's chest to his waist, pinching and twisting a bit of flesh on his waist.

"I'll teach you to play tricks on me! You're so mean, this is the punishment you deserve!"

As he spoke, he increased the pressure on his hand. Li Zhenhua knew he was in the wrong, so he could only force a smile and remain silent.

Then Li Zhenhua handed the little chestnut in his arms to Li Yun. He was going to go upstairs to change his clothes. Wearing Li Yun's clothes with two big apples stuffed inside was not a very pleasant feeling!

After he changed his clothes, holding the holographic disguise projector, he returned to the living room. Little Chestnut was engrossed in playing with her toys, while Li Yun looked at him with a serious expression.

Li Zhenhua, holding the disguised projection, approached Li Yun and turned on the device. Above him, a picture of his own head floated in the air.

Seeing this, Li Yun understood what had just happened. It seemed that it was this thing in her husband's hand that had caused the trouble. She began to complain in her heart, blaming him for making strange inventions all the time.

At this point, Li Zhenhua began to tell Li Yu about his subsequent plans. While he was talking, Xiao Lizi, who was playing with toys, also perked up his ears to listen.

After he finished speaking, Li Yun was speechless. She hadn't expected her husband to make so many preparations for their trip.

While speechless, she was also full of anticipation for their upcoming trip. The two of them were only thirty years old, and they had never really gone out to play since they got married.

After Li Zhenhua explained things to Li Yun, there was nothing more to it, just like usual.

Before they knew it, it was evening. Little Chestnut had already been coaxed to sleep by Li Yun, while Li Zhenhua went to take a shower. Li Yun, however, was watching a fake projection, and her face turned red as she watched.

The blush proved that she had clearly thought a lot. She got out of bed and went straight to the dressing room. When he came back, she had changed into a sexy and alluring outfit, but her mind had also changed.

Her head was no longer her own; it had been replaced with that of a famous teacher, and she was posed in a particularly seductive position on the bed.

When Li Zhenhua walked out of the bathroom, drying his hair with a towel, he was completely stunned. He had never imagined what was happening before him.

But he didn't dare to move, because he sensed a danger. If he made the slightest mistake, his life could be in danger.

"Xiaoyun, wife, baby, what are you doing?"

As soon as he asked the question, Li Yun walked seductively from the bed to his side. What happened next was no longer up to Li Zhenhua.

After that, the couple went on a wild spree, with Li Yun getting a head transplant and Li Zhenhua getting a new look.

After their intense battle, Li Zhenhua, panting heavily, leaned against the headboard, still feeling somewhat uneasy.

"Xiaoyun, wouldn't what we just did count as emotional infidelity?"

Li Yun took a few deep breaths, glared at him irritably, and then blushed and said shyly.

"What do you mean by cheating? We're just adding some spice, like cosplay. Besides, your car wasn't parked in anyone else's garage, and I didn't let anyone else park in mine! What cheating? We're just adding to your fun!"

Only after hearing Li Yun's answer did Li Zhenhua truly feel relieved! Now that he was at ease, he naturally wanted to play with this toy that would add some fun to their relationship, and what followed was an indescribable scene.

The next morning, when he got up, he felt completely drained. He glanced at Li Yun, who was sleeping soundly next to him, and noticed that Li Yun looked unusually healthy.

"Ah, the old saying is so true: there's no worse land, only oxen working themselves to the bone! Looks like I'll have to study biotechnology in the future, otherwise I really won't be able to keep up. Since I can't conquer you now, I'll use the power of technology to strengthen myself. Victory will come eventually."

With that in mind, Li Zhenhua set himself another task with an unknown number of stages, made a mental record of the task, and then returned to the blacksmith shop to begin creating another important technology.

The process of creating the Particle Storage Treasure is relatively simple. The innermost tungsten alloy can be directly produced using casting technology. It's just that the growth of the diamond layer takes a long time.

He picked up his old trade again at the blacksmith shop. A blacksmith can not only forge iron, but also do sand casting.

Moreover, he himself is a mechanic, and many parts in machinery are made using casting.

According to his design dimensions, the first layer of the particle storage tank was made using a wax model. Then, sand was filled into a sand box. After the sand box was filled, necessary air holes were left, and then the casting process began.

The tungsten-gold alloy he prepared in a certain proportion was melted into a golden-red flowing liquid in a smelting furnace. Then, this alloy solution with an abnormally high temperature was poured into a sand box.

Subsequently, the high-temperature alloy solution comes into contact with the sand box, and the wax model inside is directly vaporized by the high temperature and expelled from the pores. Then, the space in the sand box that was originally occupied by the wax model is filled with the alloy solution.

Next, the tungsten alloy was cooled in a sand box. Li Zhenhua used some methods during the cooling process to reduce the inevitable porosity in the alloy. When the alloy reached a certain level, the entire sand box was subjected to high-frequency vibration.

This high-frequency vibration makes the alloy more compact and prevents the formation of pores inside.

This high-frequency vibration will continue until the alloy is completely solidified. Once the alloy has cooled down naturally, the sandbox can then be disassembled.

At this point, the innermost layer of the particle storage treasure is complete. The next step is to cut the gem-quality diamonds into small pieces and then fit these pieces tightly onto the outside of the first layer of the storage treasure.

Once the first layer of diamond flakes is completely covered, the storage treasure is placed in a specific container. Then, the instrument is turned on, allowing the diamond flakes to grow within the instrument.

The growth process is actually very long, but the method for synthesizing diamonds is actually quite simple, just like producing silicon rods.

The method used by Li Zhenhua is a combination of high-temperature and high-pressure synthesis and chemical vapor deposition synthesis, which combines the advantages of both methods.

Of course, it consumes a lot of energy, requiring a large amount of electricity, as well as natural gas and nitrogen. Then, in the high-pressure and high-temperature environment of the instrument, the gas forms carbon plasma, which then slowly begins to deposit on the diamond seed.

The end result is that the diamond flakes that were originally tightly attached to the first layer will slowly grow into a whole as the sediment settles.

For the next two weeks, Li Zhenhua did not turn on the instrument. Finally, two weeks later, he calculated that the time was almost up and turned on the instrument.

The moment the instrument was turned on, the scene inside was indescribable, because he had never seen such a large diamond placed in front of him before.

The dark, slightly golden metal that was originally fed into the instrument is now encased in a thick layer of diamonds. The diamonds are so large that they shine so brightly when light hits them.

"Everyone says a diamond lasts forever, but that's utter nonsense. From now on, if anyone says diamonds are valuable, I'll argue with them!"

If this technology actually becomes available, diamond merchants will probably send people to kill me. Diamonds are a complete rip-off; they're basically just selling the cutting technique!

He took the storage treasure out of the device, stared at it for a few minutes, and then muttered something to himself.

"Sigh, this diamond is so big on the outside, but it's not very useful. In the end, I still have to polish away the diamond on the outside of the storage treasure, leaving only a five-millimeter-thick diamond layer."

After sighing, he began to ruthlessly cut the diamonds outside. If some silly women saw this scene, they would probably be heartbroken.

Who has ever seen such wasteful behavior as Li Zhenhua, cutting so many diamonds off so easily? This shows the difference in perspective and level of authority.

To Li Zhenhua, these diamonds were merely industrial products, but to that kind of woman, they were gems, priceless gems.
