"Let me tell me, what exactly is this thing?"

"Don't worry, I'm just guessing now, and I'm not sure." Zhang Yang rubbed his chin, "I can only make a conclusion after he takes action!"

Cao Nian thought about it and felt that what this guy said seemed to make sense, "Okay, then wait."

The middle-aged uncle named Ma had already put on gloves. He folded his hands together, and then suddenly pressed on the ground, "Decompose!"

A strange force surged out of the man's body.

This force was passed into the earth with his hands as a medium.

The weird 'alchemical matrix' on his gloves was emitting a yellow light!

Boom-

Centered on the cave.

The surrounding rocks and soil began to decompose and continued to fall off, turning into tiny substances flowing down the mountain like water. Tons of soil turned into torrents and flowed downwards. Those guys who could not dodge were almost washed away by the soil. Cao Nian was shocked when he saw this scene that was like a mudslide outbreak.

It can actually directly decompose matter into tiny particles?! What kind of power is this? From macro to micro, there are several orders of magnitude gaps in the middle. If this guy can decompose all matter like this, wouldn't he be able to directly turn his opponent into particles?

Zhang Yang nodded, "It's indeed alchemy! And it's quite amazing!"

"Alchemy, in the cognition of ancient people, was a 'secret technique' that could turn base metals into gold. In the era of underdeveloped technology, countless scholars have been working tirelessly to study this technique. However, in animation, alchemy is defined as a force to decompose and reorganize matter. To put it simply, it is to decompose raw materials into tiny particle states, and then reorganize these particles into what they want." Zhang Yang explained, "As long as there is a suitable proportion of raw materials and sufficient strength, it can directly refine steel bars, cement, wood and other things into what they need, such as houses!"

"It's like 3D printing?" Cao Nian asked.

"3d printing? Although it is indeed very similar, strictly speaking, 3d printing is only the second half of alchemy, which is the so-called 'reconstruction'. As for decomposition, it is something that modern technology cannot easily achieve!" Zhang Yang said.

"So, this kind of power should be considered a kind of magic, right?"

"Maybe, the so-called magic is difficult to define. However, alchemy also follows the principle of 'equal exchange', which is somewhat different from the 'creating of something out of nothing' of magic." Zhang Yang said.

Cao Nian nodded and stopped asking more questions.

And in front of them.

Accompanied by the fall of stones and soil.

This forbidden area, known as the "Death Cave", gradually began to reveal its original appearance.

"Still!" The middle-aged man roared. He exchanged his hands and pressed the other hand on the ground. The soil stopped flowing, but instead began to harden and turned into a flat platform. Above the platform, a huge building full of metallic color appeared in front of everyone.

This is--

A city of steel!

Everyone was shocked because they were standing at the door of this steel castle hidden in the mountains! In other words, this so-called "death cave" is actually just a huge steel castle hidden in the mountains!

The middle-aged man named Ma wiped the sweat from his forehead, "I can't analyze the material of this building and can't decompose it. Sorry, I seem to have to do so much."
