The Troublesome Hero Among the Heroes

Charles, who worked overtime for the Demon King in the Ekaterina Palace, drove the army preparing for a long-distance cross-regional training to the dead, and then returned to the City of Knowledge.

The time comes to the end of June, and there is less than half a month before the opening of the "City of Knowledge United Academy Carnival".

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

More enthusiastic is the various academies. Many academies, including the Shield Bridge Academy, have simply suspended classes. Spare no effort is preparing for the next event.

Charles’ students in their class were divided into two parts. One part was called by Medivh’s classmates to help in the final test of equipment such as nail machines and air hammers. The other part was called by Langsha. To help in the laboratory, her slime silk experiment had preliminary results.

"It's nice to be young." Nikolai exclaimed, looking at the busy students, "youngster is always so passionate."

He was also caught by Charles to work. Now, the task is to provide some suggestions for modification to those machines.

"Can there be no passion?" Charles helped his black-rimmed glasses. "These machines are sold at a commission."

Nicolas looked at those machines. The voice said: "I will arrange for white gloves to buy a batch of nail machines, air hammers, power picks, oil presses and glue injection machines." Gloves, he said: "When the time comes, the southern customer's order is produced in the slime basin, I will stick a card."

Nicolas asked in a low voice: "Aluminum is negotiated? "

Charles replied: "Sybil came over to talk to them, and the big frame was negotiated."

"The Bauxite Ore in Montenegro is mined in limited quantities, and the aluminum products they sell will be given A commission, and now I'm talking about the details such as the commission amount."

The group of masters want aluminum to continue to maintain the status of top luxury goods, and Charles will follow them.

Anyway, it was only in the agreement that he was restricted from mining, and Auston I and Ji Shijun, who had a full set of electrolytic aluminum technology, couldn't control him.

They will make great efforts to study aluminum alloy in the past two years, and they are too lazy to control the luxury goods market.

Now he doesn’t want to talk about it very much. He originally had a series of plans for the development of aluminum alloy. As a result, he was immediately beaten by the noble masters, and he simply regarded it as the land. Buying land is cheaper by Auston I and Ji Shijun.

"I'll go shopping at Langsha." Charles slipped away after leaving a sentence.

There is Vichy here that basically can't make mistakes, and now there is Demon King in charge, it is difficult to make mistakes.

Langsha’s slime silk experiment has been going on for more than a year. Charles spends money in it every month. During the period, he accidentally achieved several good results such as slime hard rubber sheets that can be used to build small 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, but it cannot be folded in half after being made into silk. Charles also made it. The glue injection machine.

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

Langsha's newly applied workshop is not far from Charles's workshop, just a few steps away.

Here, countless slimes are squirming in the huge tank, and a row of young men and women are slaughtering, cutting, picking, and potting each slime.

Although slime looks transparent, it also has internal organs.

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

For this, Langsha and Enrico tried many methods, and finally used the method of feeding slime to eat colored feed before processing to determine the location of the visceral area.

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

In the sound of machinery, a one-meter-long mold plate in a machine the size of a large closet slowly moved away from another fixed mold plate. After it was half a meter away and stopped, Langsha on the side took down a drying rack from above.

There is a thin piece of slime glue between these drying racks, which can be cut off with a knife, and the rest can be returned to the oven for reuse.

Today, Langsha is wearing Academy overalls and still wearing a pair of big glasses, but her fluffy and messy hair is tucked in the hat.

Charles took the hot clothes hangers she handed them and separated them, took one and waved it in his hand, it felt good, and he would surely cry Modred Pia.

Then he looked at the dark red hangers in surprise and asked: "Did you add dye to them?"

Langsha replied: "I added the juice of the ground blood grass. Otherwise, the original color is not good."

Charles nodded, the slime glue is mostly white with a little yellow or gray in it, which looks dirty.

Earth blood is a common plant. The sap is dark red like venous blood. When cooked, it turns into bright red of arterial blood. It is often used for dyeing cloth and painting.

"Is there anything wrong with the machine?" Charles asked again.

The machine runs automatically under the control of the core of the magic brain. Langsha just waits for the hanger to be removed every ten seconds.

She said: "At present, it seems that there is no problem. It is a bit wasteful to use the ice magic array for mold cooling. I think cooling water will be enough, so that the mold processing is more convenient and the running cost is lower."

Charles thought about it for a moment, and thought she made sense.

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

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

After speaking, he took the bucket with him. The mold left.

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

Charles took the Principal's approval slip and took a few long copper and rubber tubes from the Academy warehouse, and then went 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 mold installation, and then used the molten copper to connect the copper tube to the mold Fill in the gap between them.

Finally, he used a voucher for the Aixifan restaurant to find a young cultivator in the forging temple in the workshop for help, and used the divine technique to fuse the copper and iron together more firmly.

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

When he returned to Langsha’s workshop, he was still pulling a hand-push fire truck for fire fighting in the workshop area behind him.

I don't know who designed this car. There is a water spray gun powered by a water spray canister on the tank, which looks very easy to use.

Langsha was taken aback by him and asked: "Why did you bring the fire truck?"

Charles replied: "It has a lot of water, and it sprays itself. Water..."

Langsha kicked him on the calf bone before he finished talking.

After the kick, he and Langsha removed the hanger mold installed on the glue injection machine, removed the magic power circuit of the cooling magic array, and installed the modified bucket mold .

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

When the water supply pipe is installed, it is fastened with an iron wire. After the return pipe is fixed, plug it directly into the 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 the newly boiled slime glue into the slime glue container of the machine.

The cooling water system runs normally and there is no water leakage. Langsha sets the operating data of the glue injection machine on the console.

Charles reminded: "The efficiency of water cooling is not the same as magical cooling. Let's extend the cooling time by a few seconds."

Langsha thought for a while, pressing the button and said:" Let’s set it for 20 seconds, and then subtract it in two seconds."

She pressed the simulation run button after setting it up, and then pressed the start button when it was running okay.

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

"Yeah!" Langsha stuck out her tongue in embarrassment, "I forgot to turn off the original cooling system. The console did not receive a feedback signal from the cooling magic array to start."

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

The mold opened automatically soon, and a red bucket appeared.

Charles took the bucket off and observed it. The wall of the bucket was smooth and uniform in thickness.

There are ribs on both sides of the inner side of the top of the bucket. This is the place left for the iron wire handle.

Then he put the bucket on the ground and kicked it with two feet. The hardness was fair, but the toughness was slightly lacking. As long as it was not hit hard, it would be fine. For now, it is enough.

He wondered whether to open another set of molds, add some patterns to the outer wall of the barrel, and add a matching lid.

"Very good." Charles turned over the bottom of the barrel and checked it. "Is there enough materials? If there is enough, I will help my farm produce a batch while testing."

The palm of his hand stretched out in front of him and said: "The materials are okay, but the labor fee is here." Without a word, Charles put a silver light gleaming aluminum hollow butterfly hairpin in her hand. superior.
