The Last Alchemist

In the grass, Rosen's mind was completely attracted by the anomalies in the ground beneath him.

Perhaps it was because he had a little more talent and his abilities were greatly enhanced, or perhaps it was because of his peace of mind, Rosen activated his alchemical power almost instantly.

He pressed one hand on the wet soil, and the tentacles of his mind extended out into the earth beneath him.

'The soil is very fertile, with rotten grass roots, accumulated fallen leaves, mineral elements and water'

‘Strange, how can organic matter decompose so quickly? What was decomposed? The colorless and odorless gas that escapes from feces is methane. The smelly, nauseating gas is hydrogen sulfide. As small as you are, you can hardly feel that it is hydrogen gas. Full of vitality, oxygen! ’

‘Various flammable gases, plus oxygen, this is a gas bomb! ’

'Danger! ’

'It is absolutely impossible for organic matter to degrade naturally so quickly. There must be extra energy supply. Only a magician can do this! ’

In the flash of lightning, several thoughts flashed through Rosen's mind.

"Magician? There is only one magician around here, and that is Diaz Romley!"

"The gas is accumulating, but the current amount is not enough. The accumulation location is 50 centimeters deep underground. Even if it explodes now, it will not hurt me, so I am safe now. The other party's method of decomposing organic matter is quite rough and fast. It’s not fast either, maybe I can resolve it.”

Originally, the safest way now was to escape from the grass immediately, but Rosen discovered that the magician's methods were quite poor, and he suddenly thought of competing with his opponent.

Thinking like this, Rosen waved his hand to Mary beside him: "Sister Mary, there is a magician who wants to attack me. You hold Alice and hide away, at least 20 meters away, and every half a cup of tea." Change place."

Frequently changing directions can prevent magicians from attacking them.

"Huh?" Mary was startled. When she came to her senses, she no longer cared about whether she might infect her daughter. She hurriedly picked up her daughter and limped away away.

She was just an ordinary peasant woman, so naturally she couldn't feel the restlessness of the elements underground, but she had a strong sense of awe for magic, so when she heard Rosen's words, she was really frightened, and she kept stepping back, and it was enough for her to withdraw. He stopped after more than fifty meters and looked towards Rosen from a distance.

On this side, Rosen's thinking tentacles once again extended into the soil beneath him, carefully observing the situation underground.

"There is no shadow of the magician around. He must be hiding in a corner nearby. The field of view here is quite wide. You can see clearly from a hundred meters away. This means that he is hiding very far away."

"This is a traditional magician. His thinking tentacles extend extremely far and are extremely strong. He can directly break the covalent bonds in organic matter! In terms of strength alone, my opponent is at least 10 times stronger than me. If according to the game The level of power is equivalent to that of a two-star official magician."

"However, although his power is very strong, his technique is very rough. There are many meaningless operations during the decomposition process, which wastes a lot of energy. Calculated, its energy efficiency is less than 8%, and all the excess energy is turned into heat energy It is dissipated. But he is very smart and controls the heat to be transferred deep into the earth. In this way, there is almost no abnormality on the surface. "

"The mixed gas exploded under me. As long as the amount of gas was enough, even if it didn't kill me on the spot, it would still be enough to make me disabled. Coupled with the severe burns caused by the flames, the medical standards in this world are completely incompetent, so I will definitely die. ”

"If I were an ordinary person, I would definitely be doomed now. After I die, passers-by will definitely say that I was punished by the gods, and no one will investigate the cause of my death. The sneak attack method is very good, but unfortunately, you chose the wrong target. ”

If he only had the first-level Friends of Elements talent, Rosen would have run away immediately without saying anything. But now, with the second-level Friends of Elements, his power has doubled, which is enough to fight with this magician. .

Thinking this way, Rosen's mind turned to the flammable gas that had been generated.

"There is a cavity 50 centimeters underground. The gas currently stored is not much. At standard pressure, methane is half a liter, hydrogen sulfide is less than a quarter of a liter, hydrogen is half a liter, and oxygen is less than a quarter of a liter. These gases In order to create explosive power, they must be mixed evenly beforehand. If they are clearly separated and have only one contact surface, they will only burn quietly. "

"My opponent is stronger than me. I can't block his magic, but I can separate these gases."

Methane, hydrogen sulfide, and hydrogen are all reducing gases, and the two can be safely mixed together. Oxygen is an oxidizing gas and is a necessary condition for the combustion of the first three.

After a simple classification, there is only one thing left for Rosen to do, which is to purify the oxygen stored in the underground cavity.

In this way, the contest between Rosen and the magician became very, very unfair.

The magician controlled it remotely and controlled four or five types of chemical reaction processes. He also did a lot of useless work along the way, and it was also a very labor-intensive multi-line operation.

Rosen's control distance is only half a meter. He only controls a physical reaction of 'purified oxygen', which consumes at least two orders of magnitude less energy than a magician!

Taken together, Rosen is a clear winner.

This is the battle between magicians. The biggest reliance is never strength, but wisdom!

A few seconds later, Rosen finished purifying the oxygen. The oxygen in the mixed gas in the underground cavity was condensed into a very pure ball, and various combustible gases were wrapped around the oxygen.

"Pure purification can only prevent temporary danger. These gases must be burned and consumed. This is the real safety."

This process is also very simple.

Rosen's thinking tentacles are fixed on the contact surface between oxygen and mixed combustible gas. There is oxygen on one side and a mixed gas dominated by methane on the other side. What Rosen has to do is to ignite them.

'The collision method is enough to complete the ignition task. '

Before, he used the collision method to nitrate glycerin. Now, he uses the collision method to ignite methane and hydrogen. The latter does not require additional calculations and control. Just randomly collide.

This is a hundred times simpler than making nitroglycerin.

Rosen focused his mind and quickly gathered a large number of fast-running molecules, but the speed of these molecules was still not enough. But it doesn't matter. Rosen can speed them up.

After several accelerations, Rosen had an idea: "It's probably OK."

Under his control, a large number of high-speed flying methane and oxygen molecules collided head-on.

'Bang~' Rosen said subconsciously.

At the microscopic level, two groups of high-energy molecules collided violently, smashing each other's structures, releasing the energy stored in the chemical bonds, and after a series of complex processes, they were reorganized into water and carbon dioxide with more stable structures.

The released energy accelerated more molecules, more collisions occurred, positive feedback appeared, and the scale of chemical reactions increased exponentially.

In an instant, the violent chemical reaction spread from the microscopic to the macroscopic field.

With a soft sound of 'bang~', a ball of light blue flame appeared out of thin air in the underground cavity.

This ball of flame is very strange, because there is less oxygen and more methane and hydrogen, so at first glance, it doesn't look like methane and hydrogen are burning, but more like oxygen is burning.

After the ignition is completed, Rosen has less to do, and only one step is left to purify oxygen.

In the following time, the magician hiding in the dark continued to decompose flammable gases, but the oxygen in these gases was immediately purified, burned, and degraded into harmless water and carbon dioxide by Rosen, while releasing a lot of heat.

In the cavity half a meter underground, the oxygen group burned quietly for more than 20 seconds, and then it was consumed.

Rosen was not in a hurry, just waiting for the magician to decompose the oxygen. He decomposed a little, and he purified and burned a little.

In this way, time passed by minute by minute.

Slowly, Rosen found that the opponent's strength was getting weaker and weaker, and the speed of organic matter decomposition was getting lower and lower. There were even several low-level mistakes. This discovery made Rosen's heart move: 'There are so many mistakes, which means that the opponent's strength is over-consumed and has already collapsed. '

After a while, Rosen suddenly felt that the oxygen was somewhat out of control. He wanted to gather them together, but these things kept running out, as if they were being pulled by something.

Rosen was startled, then he figured it out: "Hmm~ finally found out something is wrong~ Hehe, if you want to grab it, then grab it. I wonder how long you can hold on!'

From beginning to end, Rosen was just purifying oxygen, which consumed very little energy. With the support of the second-level element friends, he was at ease and not at all tired.

At this time, he faced his opponent head-on, completely waiting for the opportunity.

Rosen concentrated on grabbing control of oxygen from the magician.

His power was weak, but he completely crushed his opponent in terms of precision. He also had the theoretical support of quantum electrodynamics, and his manipulation of microscopic particles was as unrestrained as a ghost or a god. Test.

The magician was extremely powerful, an order of magnitude higher than Rosen, but he was almost exhausted and his technique was very rough. At least 90% of his strength was spent internally, and the remaining 10%, although used in the right way, was always used inaccurately.

In the underground cavity, the two sides' strength came and went, entangled and interfered, and after a contest, they were evenly matched.

The magician seemed unwilling to give up and suddenly increased his strength.

Rosen immediately felt that a large amount of oxygen was taken away by him. He was shocked and had a strong desire to win: "You want to suppress me with force, hehe, I'll steal the beams and replace the pillars! "

He always knew that his goal was not to fight for oxygen, but to separate oxygen.

When the opponent took away the oxygen, Rosen's attention immediately shifted to flammable gases such as methane, and pulled back these reducing gases.

After some operations, the oxygen and flammable gases exchanged positions, but they were still in a safe separation state.

At this moment, Rosen clearly felt that the opponent's power suddenly paused. Half a second later, a series of low-level mistakes suddenly occurred. After another second, the opponent's power disappeared without a trace.

Rosen was a little melancholy: 'Uh~ Just leave like this?'

It's not good A magician opponent came easily. He was having a great time playing, but the opponent suddenly stopped playing without even saying hello.

‘It’s boring~ Really boring~’ Rosen sighed repeatedly.

At the same time.

About two miles away in Caopo Village, a wooden house on the hillside.

A man wearing a heavy cowhide armor robe was standing in the center of the room. Below him, he was drawing a circle with a diameter of one meter, in which an equilateral triangle was inscribed. A wooden stick was inserted into each of the three vertices of the triangle. The wooden stick was about one meter high, as thick as an arm, and had an ancient style. There was also a transparent stone on the top of the pillar that was glowing, similar to crystal.

The man looked about 30 years old, with a gloomy face and brown hair. He stood there motionless with his eyes closed.

Suddenly, the wooden stick beside the man made a cracking sound, and many cracks appeared on the wooden stick. One of the wooden sticks even broke into two pieces.

‘Cough~cough~cough~~~’

The man coughed violently and couldn’t stand up. He could only half-kneel on the ground. Coughing and coughing, he suddenly opened his mouth and spit out a large mouthful of black blood.

‘Why is this happening? ! ’

He finally couldn’t hold on. His eyes went black. He rolled to the ground with a ‘gulp’ and fainted.

Tomorrow, two updates will be resumed.

In addition, this book is not about lords and nobles, nor is it about hegemony in another world. This book is just a story about a top student applying what he has learned in another world and pretending to be a rival. That’s all.
