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

He has confirmed that penicillin is in these three bottles of solution. Now, the last step is to find the penicillin molecule.

Then, he activated the alchemy power again and immersed himself in the solution of Penicillium.

After a while, he sensed a slightly sweet and sharp murderous aura. Compared to other substances in the solution, this aura was very weak, with only a very small amount.

This kind of smell does not exist in other penicillium solutions, and Penicillium No. 15 solution is the most, followed by 9, and 7 is the weakest, which is exactly the same as the previous bactericidal effect.

Luo Sen was delighted: 'It's you!'

Finding penicillin is only the first step, and the second step is to get enough amount of penicillin to truly cure the disease.

On Earth, there are two ways to obtain penicillin: one is to breed the strains on a large area and purify them, and the other is to directly synthesize them manually.

The first method is not suitable for this world. First, the penicillium beads in this world have not been selected and the efficiency of synthesizing penicillin is not high. Second, if you want to get a sufficient dose of penicillium, you must consume a large amount of food. The world's food productivity is poor, and you are not enough to eat enough, and there is no surplus grain for refining medicine.

Therefore, we can only choose the path of artificial synthesis.

To artificially synthesize, the molecular structure of penicillin must be determined.

Rosen now regrets that he did not carefully look at the formula of the drug in Cephalo capsule when he was on Earth, otherwise he would not have had such trouble now.

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

Luo Sen's alchemy talent is correct to the molecular level, but it is not the naked eye after all. The way he senses molecules is to feel a unique aura, but his power cannot be distinguished by what atoms this aura is composed of.

‘Fortunately, I still have the collision method. I use molecules or atoms with known structures to collide with penicillin molecules, observe the collision results, and calculate them in conjunction with quantum mechanics to determine the molecular structure.’

Do it as soon as you say it.

In the following time, Rosen's spirit was sometimes immersed in the solution, controlling the water molecules to touch the penicillin molecules from various angles. Sometimes he picked up a quill and wrote rows of extremely complex calculation formulas on the parchment paper. Sometimes he lowered his head to ponder, and he was completely immersed in his own world.

I don’t know how long it took, but Luo Sen suddenly stopped in his hand. He lay on his back on the chair and let out a long sigh.

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

Luosen didn't start immediately. He sat in the chair, closed his eyes and rested. After feeling that his energy was restored, he brought the pottery jar filled with clear water from the corner of the room.

He skillfully used the power of alchemy to sterilize and disinfect the water, and then found fruits with Penicillium No. 15. These were all moldy oranges. Luosen crushed the oranges and threw them into the clean water of the pottery jar.

Penicillium No. 15 has the strongest penicillin synthesis ability, which shows that oranges contain all the elements of synthetic penicillin.

There were seven or eight kilograms of moldy oranges, and Luo Sen 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 was immersed in it, using the collision method and previous calculation results to start synthesizing penicillin.

Time passed by minute by minute. Luo Sen held the edge of the pottery jar with both hands, and his whole body remained motionless, just like a wooden carving. The only change was that fine beads of sweat were constantly seeping out on his forehead.

With the support of the 3rd level Friends of Elemental Talent, Luo Sen's alchemy power has greatly increased, but the molecules he wants to synthesize are much more complex, and the raw materials are also diverse. It is necessary to use various methods to succeed.

Under various reasons, Rosen's efficiency in synthesis of penicillin is at least three times lower than that of nitroglycerin.

On the surface, there is basically no change in moldy orange juice in the pottery jar, but in the deeper level, a large number of penicillin molecules are being produced.

After 3 hours, Luo Sen's body suddenly moved. He let out a long breath, wiped the sweat from his forehead, then picked up a glass cup and took a bottle of water into the pottery jar.

What a strange thing is that the pottery jar is obviously light yellow orange juice, but the glass is indeed clear water that looks transparent.

This is more than just a few.

Luo Sen returned to the table with the cup of clear water, sat down, and activated the alchemy power again.

The water in the glass suddenly began to surge. After a while, something white began to settle out of the clear water. The more it settled, the more it became. Finally, the white powder was spread about 5 mm on the bottom of the glass.

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

After doing all this, Rosen breathed a sigh of relief.

‘Penicillin sodium salt, 200 grams, is equivalent to 330 million units. For ordinary adults, they should only need...millions of units..., Oops, I don’t know the specific dosage....’

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

If medicine is used well, it is a medicine, and if it is poor, it is a poison. If it is poor, it is a poison that causes life!

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

I don’t know how to use the medicine, which is quite embarrassing.

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

what to do?

There is only one way before Luo Sen, that is, to do experiments and explore 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 a beacon of science, then experiments are the ship that reaches the other side of truth.

No experiments, no science.

The tall science building on Earth is built with countless ancestors, made of countless experimental bricks and stones.

‘It’s up to me to succeed.’ Luo Sen thought to himself.

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

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

On the parchment paper, not only the detailed process of discovering penicillin, but also the molecular formula and specific synthesis methods of penicillin are recorded. With these records, even if Luo Sen suddenly disappears one day, if a fellow traveler can discover these parchment scrolls, he can 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 to the best of their ability, which can at least prevent future generations from taking many detours.

After finishing the work, Rosen regained his energy, arranged normal saline, incorporated penicillium sodium salt, 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, Luosen heard a rooster crow next door. When he looked up, he saw that the horizon had turned white.

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

When he opened the wine cellar door, he saw a faint candlelight in the wine cellar, and there was a slight movement inside. It seemed that Mary and Little Alice had woken up.

‘People these days wake up so early.’ Luo Sen sighed secretly.

He walked into the wine cellar.

"grown ups."

"elder brother."

Both Mary and Little Alice greeted Rosen.

After responding one by one, Rosen knelt down next to the bed, took out the glass needle for the medicine to be placed beside him, and whispered: "Mary, I have prepared the medicine. It's time to treat it."

Mary was stunned for a moment, and subconsciously looked at the shiny glass needle. In her opinion, this thing was very beautiful and exquisite. She had never seen such a beautiful thing before, and instinctively felt that this thing might contain mysterious power.

Little Alice also calmed down. Although she was young, she had been tortured by illness. The difficulties made her mind more mature than her peers.

Rosen first picked up a needle: "Mary, arm."

He will not immediately give a large dose. Because on Earth, 10% of penicillin drugs may have allergic reactions. Before that, he must make sure that Mary will not be allergic. If so, he cannot use any penicillin drugs on Mary. He must turn to other antibiotics, which will be very, very troublesome.

Because of this, Luo Sen's heart was full of ups and downs.

Mary was also uneasy. She stared at the shiny metal needles, 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 tip of the needle, and injected a very small trace of potion.

"Ah~ it hurts~" Mary shouted subconsciously.

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

After Mary was injected, Rosen said to Little Alice again: "Alice, arm."

Little Alice was frightened by the shiny metal needle tip. She hesitated to stretch out her arm, but turned her head and didn't dare to look.

Rosen made it according to law.

As soon as the needle tip penetrated into the skin, little Alice burst into tears. No matter how precocious the mind was, she was still a child after all.

After the subcutaneous injection, Rosen waited nervously.
