The Hero Who Troubles the Heroes

Charles, who was working overtime for the Demon King in the Catherine Palace, slaughtered the army that was preparing for a long-distance cross-regional training and returned to the Knowledge City.

The time is late June, and there is less than half a month before the opening of the "Knowledge City United College Carnival".

At this time, the temperature on the island has become hot, and girls playing in the water have appeared on the beach. It is said that Diana also took Mira and Arturia to buy new swimsuits.

What is even more enthusiastic is that various colleges, including Shield Bridge College, have simply suspended classes and are going all out to prepare for the next event.

The students in Charles and his class were divided into two parts. One part was called by Medivh into the workshop to help carry out the final test on the nail machine, air hammer and other equipment. The other part was called by Langsha to help in the laboratory. The Slimes experiment has had preliminary results.

"It's nice to be young." Nicola sighed looking at the busy students, "Young people are always so passionate."

He was also brought in to work by Charles, and the task was to provide some revisions to those machines.

"Can we not have passion?" Charles helped his black-rimmed glasses. "They all get a commission when these machines are sold."

Nikolai looked at the machines and whispered, "I'll arrange for White Glove to buy a batch of nailers, air hammers, power picks, oil presses and glue dispensers back."

Charles knew that there was a batch of white elf gloves in the Rurik Kingdom, and he said: "When the order from the southern customer is produced in the Slime Basin, I will post a card."

Nikolai asked in a low voice again, "Have the aluminum matter been settled?"

Charles replied, "Sybill came over to talk to them, and the big picture was settled."

"The bauxite mines in Montenegro are limitedly mined, and they will give a commission for the aluminum products they sell. Now we are talking about details such as the amount of commission."

The gents wanted to keep the aluminum status as a top luxury item, and Charles let them.

Anyway, the only thing in the agreement is that he is limited in the amount of mining, and he has no control over what Auston I and Ji Shijun, who have a full set of electrolytic aluminum technology, do.

In the past two years, they will make great efforts to study aluminum alloys, and they are too lazy to manage the luxury goods market.

Now he doesn't really want to talk about it in his heart. He originally had a series of plans for the development of aluminum alloys. As a result, he was immediately beaten by those aristocratic gentlemen, and he simply thought that the land was cheaper than Austin. The first and century history of the army.

"I'll go shopping at Langsha." Charles left a sentence and then slipped away.

There is Vichy here, and it looks basically impossible to make mistakes, and now that there is a demon king in charge, it is difficult to make mistakes.

Langsha's slime experiment has been going on for more than a year, and Charles throws money into it every month, during which he unexpectedly obtained several good results, such as a slime hard plastic board that can be used to build boats.

One of the slime glues has good hardness and toughness. It can be used to make daily necessities such as washbasins, buckets, and drying racks. However, it cannot be folded in half after it is made into silk. Charles also came up with a glue injection machine.

The slime stockings that someone is thinking about are still not ready for the fire. Now the slime silk that is closest to success has elasticity, but the strength is not enough, and it needs to be improved.

The workshop that Langsha applied for is not far from Charles' workshop, just a few steps away.

Here, countless slimes are squirming in the huge water tank, and a row of young men and women is slaughtering, dicing, picking, and potting the slimes.

Although slime looks transparent, it also has internal organs.

After research by Langsha, these internal organs will affect the performance of slime glue after processing. It is best to remove these parts before boiling the glue.

To this end, Langsha and Enrico tried many methods, and finally used the method of feeding slimes to eat colored feed before processing to determine the location of the internal organs.

The glue injection machine that Charles took out this time has already been moved here and is undergoing trial production.

In the sound of the machine, a one-meter-long die plate in a machine the size of a wardrobe slowly moved away from the other fixed die plate. The board drying rack was removed.

These drying racks are connected by a thin piece of slime glue, which can be cut off with a knife, and the rest can be returned to the oven for reuse.

Today's Langsha is wearing the school uniform and still wearing a pair of big glasses, but her fluffy and messy hair is stuffed inside the hat.

Charles took the still-hot hangers she handed over and separated them. He took one and waved it in his hand. It felt good, and he would definitely make Mordred cry.

Then he looked at the somewhat dark red hangers in surprise and asked, "Did you dye them?"

Langsha replied: "I added the juice of the ground blood grass, otherwise the original color would not look good."

Charles nodded. Most of the slime glue was white with a little yellow or gray, and it looked dirty.

Earth blood grass is a common plant. Its sap is dark red like venous blood, and turns bright red into arterial blood when cooked. It is often used to dye cloth and paint.

"What's wrong with the machine?" Charles asked again.

The machine runs automatically under the control of the magic brain core, and Langsha just waits for the hangers to be taken off every ten seconds.

She said: "There seems to be no problem at present, but the ice magic array used for mold cooling is a bit wasteful. I think it is enough to use cooling water, so that the mold processing is more convenient and the operating cost is lower."

Charles thought for a moment, and thought she was right.

This kind of daily necessities is small profits but quick turnover, and the cost can be as low as possible.

He said: "Then I will take a mold and change it. I will change the machine at noon and try it in the afternoon."

After speaking, he took the bucket mold and left.

The bucket mold looks like two large iron cylinders, and the space in the middle is exactly the shape of a bucket after they are put together.

Charles took several long copper pipes and rubber pipes from the college warehouse with the principal's approval note, and then came to the forging workshop.

He first buckled the cooling magic array on the mold, then borrowed a station to fix the copper tube without affecting the installation of the mold, and then filled the gap between the copper tube and the mold with molten copper.

In the end, he used a voucher from the Aixi Restaurant to find a young monk in the workshop for the help of a forging temple, and used magic to fuse copper and iron more firmly.

In this way, each of these two molds has an independent "S"-shaped heat dissipation copper pipe, which should be enough.

When he returned to Langsha's workshop, he was pulling a hand-pushed fire truck for firefighting in the workshop area.

I don't know who designed this car. The water tank is equipped with a water spray gun powered by a water spray cylinder, which looks very useful.

Langsha was taken aback by him and asked, "Why did you pull the fire truck here?"

Charles replied: "It has a lot of water, and it will spray itself..."

Before he could finish speaking, Langsha kicked him on the calf bone.

After he was kicked, he and Langsha removed the coat hanger mold installed on the glue injection machine, removed the magic circuit of the cooling magic circle, and then installed the modified bucket mold.

After the mold is installed, the cooling water pipe is installed. Charles just made a tee with copper pipe, so that the water gun of the fire truck can supply water to the two molds at the same time.

After the water supply pipe is installed, it is fastened with iron wire. After the return water pipe is fixed, directly plug the water filling cover of the water tank, and then turn on the water spray switch for five minutes.

During this period, Alvin led the students to pour freshly boiled slime glue into the slime glue container of the machine.

The cooling water system runs normally without water leakage. Langsha sets the operation data of the glue injection machine on the console.

Charles reminded: "The efficiency of water cooling and magic cooling is not the same. Extend the cooling time by a few seconds."

Langsha thought for a while, pressed the button and said, "Let's set 20 seconds first, and then reduce it in two-second increments."

After she finished setting, she pressed the simulation run button, and after it ran fine, she pressed the start button.

The two molds are slowly put together, and then the "syringe" squeezes the red slime glue into the gap between the molds, and the system reports an error.

"Yeah!" Langsha stuck out her tongue embarrassedly, "Forgot to turn off the original cooling system, the console did not receive a feedback signal that the cooling magic circle was activated."

After she finished speaking, she forcibly turned off the alarm, and then adjusted it after finishing the barrel.

The mold soon opened automatically and a red bucket appeared.

Charles took down the barrel and observed ~www.wuxiaspot.com~ The barrel wall was smooth and the thickness was uniform.

The reverse side of the top of the bucket has reinforcing ribs on both sides of the inner side, here is the place left for the wire handle.

Then he put the bucket on the ground and kicked it twice. The hardness is acceptable, but the toughness is slightly lacking. As long as it is not hit hard, it will be fine. For now, it is enough.

He wondered if he should make another set of molds, add a pattern to the outer wall of the barrel, and add a matching lid.

"It's pretty good." Charles turned over the bottom of the bucket to check, "Is there enough material? If it is enough, help me to make a batch for my farm while testing."

Langsha put her palm in front of him and said, "The material is fine, but the labor fee is here."

Without saying a word, Charles placed a silvery aluminum cutout butterfly-shaped hairpin in her hand.
