The Last Alchemist

Entrance to the cave.

Rosen was not in a hurry to light the firewood. He took out the flour and water bag first. He didn't care about the taste. He took a mouthful of raw flour and drank a mouthful of water. He ate half a pound of raw flour.

The main component of flour is starch. Starch is a high-molecular polysaccharide. After hydrolysis, it is glucose, which is the main source of energy for the human body.

He was about to use alchemy at all costs. Before that, he naturally had to replenish his body energy as much as possible.

Viken on the side sneered: "Heh~ You must have starved to death in your previous life."

Rosen was full. He wiped the flour from his mouth and smiled lightly: "It's not your concern whether I starved to death. What you should care about most now is your own destiny."

"I'll just watch you toss."

Rosen stopped talking. He took a deep breath, calmed down, and activated his alchemy talent.

The first step is to light the firewood.

There was a bonfire in the cave. Although it was basically burned out, there were still many charcoal fires in the ashes. Rosen's power rolled up the sparks and ignited the firewood pile in the cave.

'Hu~Hu~'

The flames in the cave burned slowly and slowly spread to the surrounding firewood.

If it is allowed to burn freely, all the firewood in the cave can be burned clean, but it will take a long time and the temperature in the cave will not rise. Rosen must intervene in the middle.

The second step is to burn fully.

Temperature is a direct expression of energy density.

If you want a higher temperature, you need to make the energy density in the space higher.

Density~Density~As the name suggests, it is the amount of energy in a unit space. Expressed in mathematical formulas, it is the total amount of energy divided by volume.

This simple formula has explained two ways to increase energy density.

First, use a closed space to prevent rapid heat dissipation, which is the meaning of the existence of the cave.

Second, speed up the speed at which the fuel releases heat and increase the energy limit as much as possible.

The first point has been achieved, and the best way to achieve the second point is to make the firewood in the cave burn as quickly as possible.

Half a minute later, all the firewood in the cave was ignited by Rosen, and the energy release speed was greatly accelerated. The temperature in the cave began to rise sharply, and the heat wave at the top of the cave began to burst out with dark red flames.

"Hu~~~~Hu~~~~"

The wind was whistling.

The burning flames were like living things, quickly absorbing fresh air through the cave entrance. The air flow fluttered Rosen's clothes and also messed up Viken's golden curly hair.

Under the action of the fresh air flow, the fire in the cave quickly grew larger, and the temperature in the cave rose sharply.

"Hahaha~"

Viken suddenly laughed: "Little thing, is this all you have? With your broken furnace, you can only burn iron red at most, and you want to burn my body? It's just a dream!"

He was not wrong. At this moment, the black beads in the center of the cave remained the same. Although the flames were fierce, they could not destroy them.

Anne also saw this scene, but she didn't say anything, just looked at Rosen, worried and expectant.

"Hahaha~~~"

Rosen also laughed out loud: "Viken, don't be too proud, I haven't started yet!"

Step 3: Infuse oxygen!

Combustion is a chemical reaction. The more intense the reaction, the more energy is released.

How to increase the intensity? First, there is enough combustion. Second, there is enough oxygen. Third, both sides are in full contact.

With the help of the cave, a natural iron smelting furnace, the first and third points have basically reached their limits, leaving only the second point, which still has a lot of room for improvement.

In the natural environment, the temperature of firewood burning is only more than 800 degrees Celsius. If you build a furnace and add a bellows, it can be raised to about 1200 degrees. But if the firewood is burned in pure oxygen, it will burn incandescently, and the temperature will soar to as much as 1700 degrees.

1700 degrees can already melt most metals, even titanium metal.

The blacksmith's bellows couldn't do this trick of increasing oxygen concentration, but Rosen could!

"Oxygen gathers at the cave entrance! Oxygen gathers at the cave entrance!"

Rosen put all his energy on the surrounding air. He used all his strength to activate element manipulation and push the surrounding oxygen into the cave entrance to supply the firewood in the cave.

Indeed, Rosen's current ability is quite limited, but he fought desperately!

He clearly felt that his spirit was completely integrated into the air around his body. For a moment, he even had a feeling that he felt he had become the master of this piece of air.

He tried his best to catch those energetic air currents and sent them into the cave.

He also clearly felt that the starch in his stomach was digested into glucose, and after entering the body's blood, it quickly gathered towards the brain. In the brain, glucose and oxygen flowed into the mitochondria in the cells together, burning wildly, converting a large amount of ATP to supply the brain.

'Boom~Boom~Boom~'

The heart was beating violently, the head became hot, and sweat squeezed out of the pores like a waterfall.

"Ah~~~~"

Rosen roared crazily.

With full preparation, Rosen's strength was brought to the extreme.

Under his intervention, the oxygen concentration in the air entering the cave increased several times!

"Boom~~~~Boom~~~~~"

Suddenly, the flames in the cave seemed to have taken a ton of aphrodisiacs, becoming abnormally bright, and the light was so strong that it was difficult for people to look directly at it.

The flames in the cave were originally bright yellow, but now they have turned pure white. The flame waves of the flames are rolling and surging in the cave. They don't look like flames, but like boiling white magma!

Even the flames that shot out from the top of the cave turned white and shot out to a height of more than one meter.

Rosen knew it well: 'The combustion is almost incandescent, and coupled with the enclosed space of the stove, the core temperature is estimated to be close to 2000 degrees Celsius, which should be enough. ’

Standing several meters away from the cave entrance, Annie could clearly feel a rolling heat wave.

She stood blankly behind Rosen, staring at the flames in the cave without blinking, and felt an indescribable feeling of fear in her heart.

She had never seen such terrifying flames. At this moment, Rosen, who was standing at the entrance of the cave controlling the flames, was obviously a head shorter than her, and he was only a 14-year-old boy, but she saw the temperament of the Flame King in him.

A sentence suddenly came out of her mind: 'Steel surrendered to his will, flames were dominated by him, and the world trembled before his power. ’

‘Apocalypse prophecy? ’ Anne was in a daze.

After burning like this for less than 10 seconds, a very peculiar smell appeared in the air. It was very smelly, similar to burning plastic, and mixed with a disgusting fishy smell. After smelling it for a long time, Rosen felt nauseated and couldn't bear it. I feel like vomiting if I can't help it.

But he had to deliver oxygen into the cave, so he had to endure it. Anne next to him also smelled it. Her sense of smell was even more sensitive. She soon couldn't stand it anymore and squatted aside and vomited.

Viken at the entrance of the cave had obviously never seen such a fierce flame. His eyes were wide open, and there was deep fear in his eyes. He screamed like a woman: "No~~~~~How is this possible! How is this possible? !”

"Annie!" Rosen yelled.

"I'm here!" Annie stood up reflexively.

"It's time to say goodbye to Viken!"

"No~~~~I can't die! I can't die!" Viken continued to scream.

Annie didn't care. She took a step forward, grabbed the thick golden curls on Viken's head, and threw it into the white ruins with a little force.

Extinguished in flames.

"Go to hell!" cried Anne.

She firmly believes that the white flames in the cave can destroy everything!

Viken's head was spinning in the air, and his vague roar came from the air: ".The Apocalypse. He must be the Apocalypse. Ah~~~~~"

He was engulfed in flames, and his roar instantly turned into a scream. The scream lasted only a few seconds before disappearing without a trace.

Three minutes later, all the firewood in the cave was completely burned, leaving only some white ashes. Because of the terrifying high temperature, a large piece of the rock wall around the cave was melted, hanging down like candle wax.

Rosen's whole body was soaked in sweat, and he was almost exhausted.

At this moment, he suddenly felt a slight shock in his heart: 'Alchemy talent tree! ’

The vision in front of him brightened slightly, and the talent tree appeared.

Compared with before, there are two more things on the talent tree. The first is free talent points. After killing Viken, Rosen gets 1 point of his own talent, which is exactly the same as in the game.

Another thing that is not available in the game is strength proficiency.

Rosen discovered that a progress bar appeared below the Friends of the Elements talent, showing 78%. After clicking on the progress bar, a description appeared: 'Every time you use alchemical power, you can increase the proficiency of the corresponding talent. When the proficiency reaches 100%, the level of the corresponding alchemy talent can be increased. ’

‘So, there are two ways to obtain free talent points. One is to kill monsters, and the other is to use them as frequently as possible. good! This is really good! ’ Rosen breathed a sigh of relief and felt satisfied.

As long as he has the alchemy talent tree to rely on, even if this world is hell, he will have the confidence to make it back.
