The reason why Shield Bridge College can become the top three top colleges in mankind is mainly due to the professors and students in the college who live up to their youth and are brave in innovation in their pursuit of knowledge.

Professor Elbach's academic intuition is no less than a certain slap of stupid hair, and his actions are no less than a carrier of stupid hair.

After everyone improved the details of the experimental plan during the discussion, he took out the large chunks of mitral and fire gold donated by Charles from the safe without hesitation.

In order to achieve better results in the experiment, Charles also used the Misilian Golden Skin Chicken and Fire Gold Bird he lent to the academy to use in the manufacturing of this experimental equipment.

After everyone arrived at the workshop area in the southeast corner of the college, Professor Batisya personally brought a few students working by the furnace and experienced old school workers to start refining the alloys needed for the experiment.

The "magic element compressor" they made this time is a cylinder with a diameter of 1.4 meters and a length of 4 meters. It is roughly "?" along the axis section.

The diameter of the bottom of the internal fire gold alloy cone is 1 meter, 4 meters long, and the diameter of the top is 0.1 mm, which is theoretically enough to compress ordinary magic elements to the strength of the outer edge of the center of the elemental boundary. At the same time, the bottom and inclined surface of the cone are engraved with the magic element absorption and diversion magic array specially improved by Professor Kilby. The magic array material uses pure fire gold, otherwise the magic power cannot flow according to the prescribed route.

The main function of the external Mithril alloy sleeve is to prevent high-pressure magic elements from overflowing from the central cone, so the closer it is to the top of the cone, the thicker it is, and finally it is simply simplified into a cylinder with a diameter of 1.4 meters.

Considering that the melting point of the fire gold alloy is higher than that of the Misilian alloy, the cone is cast using the lost wax method, and then the pure fire gold used in the magic array is embedded in the middle of the cylindrical mold, and then the Misilian alloy is cast.

It is not easy to cast this big guy. Professor Elbach handled the special matters and asked the people in the molding workshop to cooperate with each other. He and Charles also started to help themselves.

During this period, a senior sister who worked here found the principal. She said: "Professor, if you cast something that is so long, you still have to stand it up and pour it. I'm afraid the bubbles are not easy to arrange."

Charles, who was helping to make the paraffin model, asked: "Is that okay to make the mold vibrate?"

He is using cast metal as cast concrete.

The senior sister asked him: "How to use the method to shake the mold? Do you knock it with a stick? Such a long mold must be buried underground to make it easier to pour, otherwise such a long mud mold will break."

Charles thought for a moment and asked, "Can you shake the ground with earthquake techniques?"

Professor Elbach replied: "It is feasible in theory, but you must master the strength, otherwise it will damage the mold."

There are many similar small problems, but fortunately, the principal who is in charge is experienced and solved quickly.

Everyone was busy in the workshop for most of the day. During this period, Professor Elbach, who took the opportunity to not want to deal with official documents, was arrested by his secretary.

When Professor Kilby personally took Charles and several students to carve magic circle patterns on the wax mold, the dinner delivered from the cafeteria was already cold.

But this is not a big deal for everyone. Charles threw a special magic trick over it, and bowls of braised pork rice bowls, fried eggs and tomato egg soup were hot again.

Many students were very envious of his magic and just put a lot of effort into assembling the paraffin mold.

Then he got busy again because of this magic.

After dinner, everyone started hanging sand for the paraffin mold, mixing the extremely finely ground clay into a viscous mud and applying it to the surface of the mold, and then applying a thick layer of clay.

Now that there is a special magic that someone only heats clay but not paraffin molds, we don’t have to wait for the clay layer to dry slowly. In just ten minutes, the clay mold will dry thoroughly.

Then someone took action, and the paraffin in the clay mold was heated and melted out. Finally, he used a specialized hot spring technique for paraffin to wash out all the paraffin remaining in the clay mold.

Professor Batisya was surprised at the speed of the mold, and his refining of fire-gold alloys was one step slower.

Next, Charles and the others had to do was dig a hole in a specific location in front of the smelting workshop and then put down the clay mold.

This is also impossible. The outlet of the furnace in the workshop is too low compared to the cone. When pouring a big guy, you can only dig a hole outside and put the mold down, and then use the diversion trough to inject the mould into the mold. In ancient times, Charles' hometown, he did almost the same thing when casting a huge copper bell.

Digging a pit or something is not a big deal for Charles. In the knowledge city, he thinks he is third, but no one dares to call himself second.

However, when the other students saw that he had used a few magics just now, they were embarrassed to bother him again, so they asked him to rest aside and everyone went to dig a hole.

He found a long chair, sat down with a cup of tea next to the clay mold that he had finally pushed over with a string of flat-panel carts, and put the mold in the pit together.

The one sitting there drinking tea was a short but strong senior brother. Charles asked him, "Why don't you dig a hole?"

The short senior brother said depressedly: "I'm too short. They said it's hard to get out if I get into the pit."

He then pointed to the clay mold behind the two and asked, "I'll ask you something, is the academy making this time?"

Charles raised his brow and asked, "Why do you think?"

The old man said mysteriously: "With such a big pointed head, I have used fire gold again. Don't you have to use it on a very powerful weapon?"

"I think this is the tip of a huge spear. Think about the magic circle above, it obviously stabbed the enemy and poured the fire element into the enemy's body."

"I guess, this weapon is prepared for the necromancer behind the space gate. We will give him this moment as soon as He appears."

Charles just smiled and said, "I think you're saying it makes sense, but the gun head is so big, and the barrel is even bigger. Who can afford it?"

The brother thought for a while, then said excitedly: "It doesn't have to be picked up by someone."

"You have seen the excavator in Nanhai Farm. Make it bigger and then replace the bucket with the palm of the machine so that you can throw such a large spear out!"

Charles thought for a moment, nodded and said, "You're very reasonable."

The old man suddenly felt excited. He continued, "One hand alone is not enough. I think it's better to change the excavator's spider leg chassis to human legs, and install hands on both sides, so that you can fight with such a big spear like a human!"

Charles was so funny, okay, is this going to do Gundam or Zagu?

He asked, "Then how do you plan to control such a large machine?"

"You're Charles Medivh?" A thin boy with a pale melon-shaped face suddenly appeared in front of the two people talking about the huge robot, interrupting their conversation.

Charles looked up and saw a guy looking at him with his nostrils. That's right, this is Tom from the Hosford family.

After all, this guy's name comes from his grandfather, so someone still replied politely: "I am Medivh, who are you?"

Who knew that Tom said angrily: "Why don't you come to my banquet tonight?"

Charles was confused, "What banquet?"

Tom suddenly roared like a firecracker, "What are you pretending? My housekeeper sent the invitation to your dormitory the night before yesterday."

Charles was speechless. He lubricated the machine model the day before yesterday. After demonstrating the machine model at night, he went to the mangroves. Then he encountered Mosla and Lao Zang. Later, he followed several orcs and drank all night at the midnight snack stall with the Fire Ape sister. He went to the mangroves at dawn and didn't find Lao Zang killed, so he caught a fat duck to Diana's house. He returned to the academy early this morning and started to work on this magic element compressor until now, and he has not returned to the dormitory at all.

But he went to the mangroves and had sex all night and appeared as McGarden, so he explained to Tom: "I'm so sorry. I was busy in the workshop since the day before yesterday. After the principal and the others left in the evening, I went to my girlfriend's place. I returned to the college early this morning and was busy with the matter here. I haven't returned to the dormitory. I really haven't received your invitation."

He now understood Tom's meaning. He probably had this guy slapped in the face by the mitril silver golden chicken he took out, so he wanted to regain the place with aluminum tableware. After all, his mitril silver was given by his classmate McGarden, and this kind of aluminum tableware was bought by himself, which was not the same thing.

As a result, when this guy was pretending, he found that the important person in this scene did not appear and punched the air, so he felt very upset.

Unexpectedly, Tom said coldly: "It's okay if you don't give me face, there's no need to make excuses."

Charles frowned, what does this guy want to do?

At this time, the old man who was interrupted by the huge robot chat was very unhappy. He waved his hand like a fly and said to Tom impatiently: "Okay, OK, Medieval has so many projects on him and is busy all day long, so how can he have time to eat, drink and have fun? This is a smelting workshop, and idle people are not allowed to come in at will. As you are a freshman, I won't let the Feng Discipline Commission punish you, so you can leave quickly."

Tom seemed to be under great insults, and his face turned red with anger.

"What are you? You dare to talk to me like this!"

After he said that, he kicked the brother, and a blue light lit up on his feet.

Charles didn't expect him to take action suddenly and had no time to stop him.

The brother's reaction was very fast and he immediately dodged to the side.

Tom kicked the long wooden chair under Charles' butt to pieces, but the blue light on his feet did not disappear, forming a wind blade and then rushed straight to the clay mold.

There was only a "boom" sound, and the mold was hit by the wind blade, and dust suddenly flew.

Charles almost fell to the ground. He looked at the place where the mold was placed like everyone else present. He saw that the mold had been made for most of the day and exploded into two pieces.
