Cave entrance.

Luosen 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 and ate a bite of raw flour, then took a sip of water, and then ate half a pound of raw flour.

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

He is about to use alchemy regardless of everything, and before this, he will naturally replenish his body energy as much as possible.

Viken, who was standing beside him, sneered: "Ha~ you must have starved to death in your previous life."

Rosen was already full, and he wiped the flour from his mouth and smiled faintly: "Do I starve to death and you don't care about it? What you should care about the most now is your own destiny."

"I'll just watch you make trouble."

Luo Sen stopped talking, he took a deep breath, calmed down, and activated the alchemy talent.

The first step is to light the firewood.

There was a bonfire in the cave, and although it had basically burned out, there was still a lot of charcoal fire in the ashes. Luosen's power rolled up the sparks and ignited the pile of firewood in the cave.

‘Hu~Hu~’

The flames in the cave were slowly burning, and at the same time 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 cannot rise. Luosen must interfere in the middle.

The second step is to burn thoroughly.

Temperature is an intuitive expression of energy density.

To have higher temperatures, you need to make the energy density in the space higher.

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

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

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

Second, speed up the fuel's heat release rate and increase the energy limit as much as possible.

The first point has been achieved, and to achieve the second point, the best way 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 Luosen, and the energy release speed was greatly accelerated. The temperature in the cave began to rise sharply. The heat waves at the entrance of the cave at the top of the cave began to burst out, and dark red flames began to burst out.

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

The wind whistles.

The burning flames were like living creatures, quickly absorbing fresh air through the entrance of the cave. The airflow blew Rosen's clothes and blew Viken's golden curly hair.

Under the action of fresh airflow, the fire in the cave grew rapidly and the temperature in the cave rose sharply.

“Hahaha~”

Viken suddenly laughed: "Little guy, are you just the trick? Just your broken furnace can burn iron red at most and 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.

Annie 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 too early, I haven't started yet!"

Step 3: Infusate oxygen!

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

How to increase the intensity? First, there is sufficient burning substances, second, there is sufficient oxygen, and third, there is sufficient contact between the two parties.

With the help of the cave, a natural iron smelting furnace, the first and third items have basically reached their limits, with only the second one left, and there is still a lot of room for improvement.

In natural environment, the temperature of firewood burning is only more than 800 degrees Celsius. If a stove is built and a bellows are added, it can be increased to about 1,200 degrees. But if the firewood is burned in pure oxygen, the combustion will become incandescent and the temperature will soar violently to 1,700 degrees.

At 1700 degrees, it can melt most of the metal, and even metal titanium cannot be stopped.

The blacksmith's bellows can't do this trick to increase oxygen concentration, but Rosen can do it!

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

Rosen devoted all his energy to the surrounding air. He used all his strength to activate elemental control, pushing the surrounding oxygen into the entrance of the cave to burn fire in the cave.

Indeed, Rosen's ability is currently quite limited, but he tried his best without hesitation!

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

He tried his best to grab the vibrant airflow and sent them into the cave with all his might.

He also clearly felt that the starch in his stomach was digested into glucose, and after entering the blood of the body, it quickly gathered towards the brain. In the brain, glucose and oxygen poured into the mitochondria in the cells, burning wildly, converting a large amount of ATP for use by the brain.

‘Dong~Dong~Dong~’

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

“Ah~~~~~”

Rosen roared wildly.

With full preparation, Rosen's power was exerted to the extreme.

Under his interference, he entered the air in the cave and the oxygen concentration increased several times!

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

Suddenly, the flames in the cave seemed to knock a ton of aphrodisiac, becoming extremely bright, and the light was so strong that it was a bit impossible to see directly.

The flames in the cave were originally bright yellow, but now they have turned into pure white. The flame waves of flames rolled and surged in the cave, not like flames, but like boiling white magma!

Even the flames that emerged from the top of the cave turned white and rushed out more than one meter high.

Luo Sen knew in his mind: "The combustion is almost incandescent, and with the enclosed space of the furnace, the central temperature is estimated to be close to 2,000 degrees Celsius, which should be enough."

Anne stood a few meters away from the cave entrance and could clearly feel a rolling wave of heat.

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

She had never seen such a terrifying flame. At this moment, Luo Sen, who was standing at the entrance of the cave, was obviously a head shorter than her, and was obviously just a 14-year-old boy, but she saw the temperament of the King of Fire in him.

A word suddenly emerged from her mind: ‘The steel surrenders to his will, the flames hold him as the master, and the world trembles before his power.’

‘Did the apocalypse prophecy?’ Anne was a little dazed.

After less than 10 seconds of burning, a very strange smell appeared in the air, which was very smelly, similar to plastic burning, and mixed with a nauseous fishy smell. After a long time of smell, Rosen felt nauseous and couldn't help but want to vomit.

But he had to transport oxygen into the cave, so he could only endure it. Anne beside him also smelled it, her sense of smell became more sensitive and she could not bear it soon, so she squatted aside and vomited.

Viken at the entrance of the cave had obviously never seen such a violent flame. His eyes were wide open, and a strong fear flowed out of his eyes. He screamed like a woman: "No~~~~ How is this possible! How is this possible!"

"Anne!" Rosen shouted.

"I'm here!" Anne stood up like a conditioned reflex.

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

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

Anne didn't care about him. She took a step forward, grabbed the thick golden curly hair on Viken's head, and threw it into the white ruin with a slight force.

In the flames.

"Go to die!" Anne screamed.

She firmly believed that the white flames in the cave could destroy everything!

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

He was swallowed by the flames, and his roar instantly turned into a scream. The scream lasted for only a few seconds and disappeared without a trace.

Three minutes later, all the firewood in the cave was burned completely, leaving only some white ashes. Because of the terrifying high temperature, the rock walls around the cave were melted and hung down like candle oil.

Luo Sen 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 me lit up slightly, and the talent tree appeared.

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

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

Luo Sen discovered that a progress bar appeared below the Friends of Elements talent, with the words 78% displayed on it. After clicking on the progress bar, an explanation appeared: "Every time you use the alchemy power, you can improve the proficiency of the corresponding talent. When the proficiency reaches 100%, you can increase the level of the corresponding alchemy talent."

‘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. Not bad! This is really good!’ Luo Senda breathed a sigh of relief and felt satisfied.

As long as he has the support of the alchemy talent tree, even if the world is hell, he will have the confidence to break back and forth.
