The Last Alchemist

After coming out of the wine cellar, Rosen was not idle for a moment. He entered the room, relit the candle, took out the glass cups of No. 7, No. 9, and No. 15 penicillin solutions and placed them on the table.

He had already determined that penicillin was in these three bottles of solution. Now, the last step was to find the penicillin molecule.

Then, he activated the alchemical power again and immersed himself in the penicillin solution.

After a while, he sensed a slightly sweet breath with a sharp murderous intent. Compared with other substances in the solution, this breath was very weak, only a little bit.

This breath did not exist in other penicillin solutions, and the No. 15 penicillin solution had the most, followed by No. 9, and No. 7 was the weakest, which just matched the previous sterilization effect.

Rosen was delighted: 'It's you! '

Finding penicillin is only the first step. The second step is to get enough penicillin to really cure the disease.

On Earth, there are two ways to obtain penicillin. One is to breed strains on a large scale and then purify them, and the other is to directly synthesize them artificially.

The first method is not suitable for this world. First, the penicillium beads in this world have not been optimized, and the efficiency of synthesizing penicillin is not high. Second, in order to obtain a sufficient dose of penicillium, a huge amount of food must be consumed. The food productivity in this world is pitifully low, not enough to eat, and there is no surplus food to make medicine.

Therefore, the only choice is artificial synthesis.

If you want to synthesize artificially, you must determine the molecular structure of penicillin.

Rosen now regrets that he did not look carefully at the drug molecular formula of cephalosporin capsules when he was on Earth, otherwise he would not have to go through so much trouble now.

"Forget it, forget it, the past cannot be pursued. There is penicillin in my solution, and I have already located it. It is not difficult to determine the molecular formula."

Rosen's alchemy talent is fine to the molecular level, but it is not the naked eye after all. The way he senses molecules is to feel a unique breath, but his power cannot distinguish what atoms this breath is composed of.

'Fortunately, I still have the collision method. Use molecules or atoms with known structures to collide with penicillin molecules, observe the collision results, and then calculate with the application of quantum mechanics to determine the molecular structure. ’

Just do it.

In the following time, Rosen's mind was sometimes immersed in the solution, controlling the water molecules to touch the penicillin molecules from all angles. Sometimes he picked up a quill and wrote lines of extremely complex calculation formulas on parchment, and sometimes he lowered his head to think, and the whole person was completely immersed in his own world.

I don't know how long it took, Rosen's quill suddenly stopped, he lay back on the chair and took a long breath.

‘Success. The molecular structure of penicillin, the synthesis method, the sodium salt, the potassium salt, and the amino substitution method are all available. The next thing to do is to start the synthesis. ’

Rosen didn't start right away. He sat on the chair, closed his eyes and rested. After he felt that his energy was restored, he moved the pottery jar filled with clean water from the corner of the room.

Skillfully use alchemical power to sterilize the water, and then find fruits with Penicillium 15. These are all moldy oranges. Rosen crushed the oranges and threw them into the water in the pottery jar.

Penicillium 15 has the strongest ability to synthesize penicillin, which means that oranges contain all the elements for synthesizing penicillin.

There are seven or eight kilograms of moldy oranges. Rosen threw them all into the pottery jar, and the water in the pottery jar turned into a ball of yellow moldy orange juice.

Taking a deep breath, Rosen's spirit immersed in it, using the collision method and the previous calculation results, began to synthesize penicillin.

Time passed by minute by minute, Rosen held the edge of the pottery jar with both hands, and his whole body remained motionless, just like a wood carving. The only change was that fine beads of sweat continued to seep out of his forehead.

With the support of the third-level element friend talent, Rosen's alchemical power has greatly increased, but the molecules he wants to synthesize are also much more complicated, and the raw materials are also diverse, so he must use a variety of different methods to succeed.

For various reasons, Rosen's efficiency in synthesizing penicillin was at least three times lower than that of synthesizing nitroglycerin.

On the surface, the moldy orange juice in the ceramic jar showed no changes, but deep down, a large number of penicillin molecules were being produced.

After three hours, Rosen's body suddenly moved. He exhaled, wiped the sweat from his forehead, and then picked up a glass and scooped a bottle of water from the ceramic jar.

The strange thing was that the ceramic jar was clearly filled with light yellow orange juice, but the glass scooped up what looked like transparent water.

That's not all.

Rosen returned to the table with the glass of water, sat down, and activated his alchemical power again.

The water in the glass suddenly began to surge, and after a while, white things began to precipitate from the clear water, and the more they precipitated, the more they precipitated. Finally, the white powder spread a layer of about 5 mm at the bottom of the glass.

Rosen suppressed his excitement, took out a new glass cup with both hands, activated his alchemical power again, fished the white powder out of the water, put it in a clean cup, and then carefully sterilized and sealed the cup.

After doing this, Rosen was completely relieved.

‘Penicillin sodium salt, 200 grams, equivalent to 330 million units, an average adult should only need a few million units for one treatment. Oops, I don’t know the specific dosage’

Soon, Rosen discovered a new problem, that is, he didn’t know the specific dosage.

Medicine is a medicine if used properly, but it is poison if used improperly. If penicillin is used improperly, it is a deadly poison!

‘It’s embarrassing. ’ Rosen scratched his head subconsciously.

It’s embarrassing to have medicine but don’t know how to use it.

In this alien world, he should be the first to use penicillin to treat syphilis macules, and it is impossible to ask anyone for advice.

What to do?

There is only one way in front of Rosen, that is to do experiments and grope forward bit by bit.

Compared with other disciplines, science has two significantly different characteristics. The first is the introduction of mathematics. The second is that everything is based on experiments.

If mathematics is the lighthouse of science, then experiments are the boats that reach the other side of truth.

Without experiments, there is no science.

The tall scientific building on the earth is built piece by piece by countless predecessors using the bricks and stones of countless experiments.

‘I can only rely on myself, and I hope I can succeed. ’ Rosen thought to himself.

It may succeed, but it may also fail. Rosen has no idea at all.

Before starting the treatment, Rosen began to collect and organize the parchment scrolls that recorded the experimental records.

The parchment not only recorded the detailed process of discovering penicillin, but also the molecular formula of penicillin and the specific synthesis method. With these records, even if Rosen suddenly disappeared one day, if a fellow traveler could find these parchments, they would be able to meet his thoughts in the book and absorb his wisdom.

On the road of science, specific people can fail, but wisdom and experience must be passed on as much as possible, which can at least help later generations avoid many detours.

After finishing the arrangement, Rosen regained his spirit, prepared physiological saline, blended sodium penicillin, and extracted it with a syringe. Then, he took the syringe and walked towards the wine cellar again.

As a result, as soon as he walked into the yard, Rosen heard a cock crowing next door. When he looked up, the sky was already white.

‘Is it dawn so soon? I don’t feel tired. ’

When he opened the door of the wine cellar, he saw a faint candlelight in the wine cellar, and there were subtle movements coming from inside. It seemed that Mary and little Alice had woken up.

‘People wake up really early these days.’ Rosen sighed secretly.

He walked into the wine cellar.

“My Lord.”

“Brother.”

Mary and Little Alice both greeted Rosen.

After Rosen responded one by one, he knelt down beside the bedclothes, took out the glass syringe filled with medicine and placed it beside him, and whispered: “Mary, I have prepared the medicine. It can be treated.”

Mary was stunned for a moment, and her eyes subconsciously looked at the shining glass syringe. In her opinion, this thing is very beautiful and very delicate. She has never seen such a beautiful thing, and instinctively feels that this thing may contain mysterious power.

Little Alice also calmed down. Although she is young, she has been tortured by illness, and difficulties have made her mind more mature than her peers.

Rosen picked up a syringe first: “Mary, arm.”

He would not give a large dose injection immediately. Because on Earth, there is a 10% chance of allergic reaction to penicillin drugs. Before that, he had to make sure that Mary was not allergic. If she was, he could not use any penicillin drugs on Mary. He would have to turn to other antibiotics, which would be very troublesome.

Because of this, Rosen was in a state of anxiety.

Mary was also uneasy. She stared at the shiny metal needle, not knowing what Rosen was going to do.

Rosen took a deep breath, pinched Mary's arm, picked up a piece of intact skin with the needle tip, and injected a very small amount of medicine.

"Ah~ It hurts~" Mary shouted subconsciously.

Rosen immediately said: "It hurts a little, bear with it."

After injecting Mary, Rosen said to little Alice: "Alice, arm."

Little Alice was frightened by the shiny metal needle tip and trembled. She stretched out her arm hesitantly, but turned her head away and dared not look.

Rosen did the same.

As soon as the needle tip pierced the skin, little Alice cried out "Wow~". No matter how precocious she is, she is still a child after all.

After the subcutaneous injection, Rosen waited anxiously.

Up to now, he had done everything he could, and the result would depend on whether God would give him face.
