My supermarket is connected to all worlds, and I've won so much money handing it over to the st

Finally, with ten seconds left, Professor Wang stepped into the classroom wearing his hat.

Everyone breathed a sigh of relief, but then realized that something seemed amiss.

"Professor Wang used to say that we shouldn't wear hats to class, what's he doing?"

"Could it be that Professor Wang encountered some terrible hairdresser yesterday and ruined his hair, so he has to wear a hat, hehehehe."

"And it's so strange, Professor Wang's face seems to have gotten smaller, don't you think so..."

"No, it's that the hat got bigger, stretched out, and Professor Wang's head got bigger?"

……

The crowd buzzed with discussion, but Professor Wang simply smiled, placed his book on the podium, and then pointed to the top of his head, saying, "It seems the students have already noticed my unusual behavior."

"There's a huge secret hidden under this hat of mine, one that you wouldn't believe if I told you, but I'm here to tell you, it's true."

Professor Wang smiled and kept everyone in suspense, explaining that he had already discussed it with Old Man Wei and that he would act as the "leaker" of the hair growth cream.

He's the one who's initiating things, giving everyone a heads-up and a heads-up.

The student craned his neck curiously, but couldn't figure out the secret.

"Teacher, please tell us quickly! What's the secret? How will we know if we'll believe you if you don't tell us?"

"Yes, Professor Wang, please stop keeping me in suspense and tell me quickly."

"Professor Wang, you're not hatching chicks on your head during experiments, are you?"

……

"This student is half right. I am indeed conducting an experiment, but it's not hatching chicks; it's a hair growth cream experiment. It's our official experimental product, and it has a 99.99% success rate. Do you remember how I looked with a slight receding hairline before? In a week, you'll witness the miracle."

Professor Wang became more and more excited as he spoke, eagerly awaiting that moment.

But the students all laughed and shook their heads.

"Professor Wang, are you really not just fooling us? You're not going to get a hair transplant this week and then tell us you have hair growth cream next week, are you?"

"The authorities have really seen our real needs, haven't they? If someone else said that, I would definitely think they were going to start a micro-business, but when Professor Wang said it, I found it somewhat credible. However, this surprise is so overwhelming that I can hardly accept it for a while."

"Teacher, your slight bald patch means there are no hair follicles left. Can it really grow back? Wouldn't it be too fake to make something out of nothing?"

……

Professor Wang listened to everyone's discussion for a while before clapping his hands to signal for quiet. "Very good. I am very pleased with your skeptical attitude. History requires skepticism... As for the truth or falsehood, we'll see when we have class again in a week, won't we?"

"Hair transplantation is like robbing Peter to pay Paul; it will definitely be obvious at a glance."

Just wait and see; he's going to openly and honestly amaze everyone.

The students were full of anticipation; who wouldn't want to grow a full head of hair out of thin air?

The news got out, but nobody believed it. Everyone was eager to see Professor Wang prove wrong, so his elective courses were booked up again next week.

……

The world of merfolk, an underwater city.

The banquet ended in the afternoon, and Gu Xixi led the Mermaid King to the center of the plaza in the underwater city to look at the supermarket.

When they arrived, there were already many merfolk queuing up at the entrance of the underwater version of the "Get Rich Quick" supermarket.

The mermaids and civilians waved happily when they saw them.

"Greetings, Your Majesty the Mermaid King! Gu Xixi welcomes you to the underwater city!"

"Sister Xixi, your tail is so beautiful! You must be a kind human being. I like you!"

"Boss Gu, hurry up and open the supermarket! We can't wait to buy some delicious food."

……

Ran Qing and others immediately opened the supermarket doors and began business.

"How did they know the rules of Fa Da Cai Supermarket?" The queue was so neatly arranged.

Gu Xixi kept wagging her tail as she swam forward, saying, "Hello, welcome to Fa Da Cai Supermarket."

"When you said the supermarket landed, I had someone notify all the citizens of the underwater city." The Mermaid King walked gracefully behind her, swishing his tail, a style completely different from hers.

Gu Xixi looked at it and tried to learn, but ultimately couldn't grasp the essentials and simply gave up.

Seeing that the supermarket was operating normally, she then led Old Yang and the others to follow the Mermaid King to investigate those few methane hydrate resource sites.

After exploration, these resource-rich areas were found to be of great exploitation value.

However, it is currently uncertain how to extract the water. If the water-storage sphere is usable, then modern extraction methods can be used, and one of the four methods can be chosen.

Gu Xixi lowered her head and began to think.

If the thermal ignition method is used to release natural gas by heating combustible ice and decomposing the hydrate, it is essential to effectively solve how to efficiently collect and store the natural gas after decomposition.

They didn't know the water storage sphere could do that. If it could... then they could mine combustible ice on their own and with the Shark King's magical sharks, without relying entirely on the Shark King's magical sharks.

The time, manpower, and resources saved in this way can be used to do many other things in the vast ocean.

This could be considered as alternative option 1.

If the decompression method is used to reduce the pressure of the combustible ice reservoir, it will promote the decomposition of combustible ice and release natural gas... However, this method requires the formation of a low-pressure zone near the borehole, so that methane gas can converge from the high-pressure zone to the low-pressure zone and then enter the collection pipeline to rise to the sea surface.

This place is not the same world as the modern world, and the sea level is not the same either, so there's no need to even think about it, pass.

If the chemical reagent injection method is used, methanol or ethylene glycol, or other chemical reagents, are injected into the methane hydrate reservoir to cause its decomposition. This requires addressing the environmental impact of the chemical reagents and the issue of collecting the decomposed gases.

With so many merfolk living nearby, they certainly can't destroy other people's living environment, so they have to pass.

8204; There is also the carbon dioxide replacement method 8204; which injects carbon dioxide gas into the combustible ice reservoir, replacing methane molecules in the combustible ice with carbon dioxide molecules, thereby releasing methane and sequestering carbon dioxide.

This method requires solving the problem of how to efficiently replace and collect methane gas, which is actually more complicated than the first method, so Gu Xixi also rejected it.

Therefore, Option 1 is currently the only feasible method, but it's not enough. So Gu Xixi looked at the Mermaid King again. "Canglin, could you have the magic mermaid demonstrate how you collect combustible ice?"

Perhaps we can find some inspiration in it.

The Mermaid King waved his hand, and several dark-skinned merfolk appeared.

Gu Xixi: No wonder I didn't notice it much earlier, this skin color is too inconspicuous.

Then, those dark, magical sharks spat out several large bubbles, encasing the collected combustible ice blocks inside, and that was it.

Gu Xixi: ……

Such a collection... it would be quite troublesome to bring back. It's her fault for not asking clearly and for not sparking any inspiration. Now it seems that waiting for news about the jadeite and the original plan of alternative option 1 is more reliable.
