"Forging these things is not difficult."

Lei Yan didn't like reading, so Su Yuan gave her a physical item he had redeemed through the system. After looking at it for a few moments, she nodded and put down the large copper pot in her hand with a puzzled expression.

“Those little things are a bit difficult, but no problem, my apprentice can handle them.”

"Your apprentice?"

Lei Yan summoned a girl with dark skin, short hair, and a bright smile. She had particularly large bull horns on her ears, and her hands bore the marks of blacksmithing.

"Chief, my name is Xingyan!"

"You are... a magician?" Su Yuan looked her up and down, his elemental energy involuntarily overflowing from his body.

"Yes, according to the leader, I am a third-tier mage!"

These days are strange; even mages are blacksmithing. Su Yuan looked at her with suspicion. Although the beast girl who became a mage was quite powerful, blacksmithing was still more strenuous than that of an awakened warrior.

I've seen magicians who run shops, and I've also seen magicians who have worked in government, but magicians who forge blacksmiths are very rare.

"......."

Su Yuan looked at Lei Yan, who then realized what was happening and said to Xing Yan, "Xing Yan, forge these items using iron ore."

Those items were all important instruments for the steam engine, such as pipes, pistons, cylinders...

"No problem, I'll give it a try first."

Xingyan nodded in agreement, then went to the forge and skillfully heated several pieces of iron ore into molten iron. At the same time, he took out his staff and began to cast a spell.

"???"

Su Yuan stared blankly as the molten iron began to float in mid-air and take shape, turning into objects exactly like the items he had previously exchanged.

Lei Yan, who was standing beside him, didn't just watch. He took some materials and planned to try to forge it using the original method.

Half an hour later, as the molten iron gradually cooled and turned into an iron block, Xingyan put it into the water. With the sound of the water boiling, the magically crafted part was completed.

"Chief, it's done."

Xingyan took out a piece of bread that restored his magic power and ate it, then handed it to Su Yuan.

No wonder Lei Yan said this guy could do it; I didn't expect him to be a gold element mage. It's just that there seems to be something wrong with the magic he's learned.

Instead of learning highly aggressive metal element attack magic from Lu Ling, she learned some minor magic to control metal.

However, Moon Pivot City hadn't reached the point where just any mage would have to be dragged into the battlefield, so Su Yuan didn't dwell on it any longer. Instead, he began to examine the cylinder in his hand.

The requirements for making this are that the inner wall is smooth enough to ensure that the piston can operate normally, and the inner diameter must also be consistent.

Although the inner wall of the part made by Xingyan was smooth enough, the inner diameter was visibly off-center, so he called Xingyan over to prepare to make the next part.

Lei Yan listened attentively from the side while simultaneously refining his own work.

Hearing the commotion, many of the beast girls working in the experimental institute gathered around, turning what was supposed to be a small experiment into a lively research and development conference.

As dusk fell, the firelight in the experimental institute remained as dazzling as the sun. The piles of iron ore were gradually decreasing, turning into tools of various shapes and sizes.

Finally, after several days and nights, Su Yuan finally assembled a steam engine, a Newcomen steam engine that works by atmospheric pressure.
