Raozhou City didn't change in the slightest because of the absence of Mo Wuji. Even Aunt Lu, Mo Wuji's landlady, was only slightly concerned, unable to take any action to find him.

Since starting the production of penicillin, Mo Wuji had been staying at the Danhan Pharmacy. Producing penicillin was too easy for him. Not to mention him, some university graduation projects had similar topics. Moreover, the technology of Chengyu Kingdom was quite decent, and the required machines could be found, requiring only slight modifications.

The only difficulty facing Mo Wuji was converting the intramuscular and intravenous injections into oral penicillin. Injection was too troublesome, and it also involved the popularization of injections.

He could produce oral penicillin, similar to amoxicillin, ampicillin, and penicillin V potassium tablets, but it would definitely take more than two months to create them.

With ordinary injectable penicillin, stomach acid would destroy almost ninety-nine percent of the pharmacological components. For others, this might be difficult, but Mo Wuji only felt slightly troubled. Back on Earth, he had stood at the top of the entire field of pharmacy. Although he couldn't completely prevent the oral efficacy of penicillin from being wasted, he could ensure that thirty to forty percent of the efficacy was successfully preserved.

In a place where antibiotics had never appeared, not to mention thirty to forty percent efficacy, even half a percent efficacy would have an astonishing effect.

As for penicillin skin tests and antibiotic reactions, Mo Wuji directly discarded them. Compared to the effects of penicillin, those slight side effects were nothing. At most, he would explain it in the instructions, and that was all.

...

For the people of Raozhou City, the biggest change recently was Danhan Pharmacy. Danhan Pharmacy had been reduced to a single store and a workshop. Now, even that one store had closed a month ago, no longer selling any medicines.

Logically, Danhan Pharmacy was about to go bankrupt and sell the store. What was puzzling was that Danhan Pharmacy not only didn't sell the store, but recently launched new advertisements throughout Raozhou City.

Nine Lives Healing Liquid, the latest product developed by Danhan Pharmacy at a cost of tens of millions. This was a boon for humanity. With Nine Lives Healing Liquid, there was no longer any need to worry about wound infections. Its efficacy far exceeded that of any previous Danhan Pharmacy product by several times. The slogan of Nine Lives Healing Liquid was: "For wound infections, as long as you have a breath left, it can give you another life." Of course, the advertisement didn't say a word about whether these tens of millions of giant sums were gold coins, silver coins, or copper coins.

The previous healing medicines of Danhan Pharmacy were not much worse than other healing medicines. Now, the advertisement for Nine Lives Healing Liquid said that it far surpassed previous Danhan healing products by several times, which implicitly meant that Nine Lives far surpassed any healing product on the market by several times.

One stone stirred up a thousand waves, and this advertisement immediately focused all the eyes of Raozhou City on Danhan Pharmacy. Raozhou was the capital of Chengyu Kingdom, which meant that the eyes of the entire Chengyu Kingdom were focused on Danhan Pharmacy.

For a time, countless people flocked to the Danhan Pharmacy store, wanting to buy a bottle of Nine Lives Healing Liquid, wanting to know if it was true.

Chengyu Kingdom was almost constantly at war, and countless people died from wound infections every day. Even apart from the army, mercenaries, hunters, herb gatherers, ore seekers... all these people were constantly facing the threat of death from wound infections. If there really was such a healing liquid like Nine Lives, who wouldn't want it?

...

On the second floor of the Danhan Pharmacy workshop, Lu Jiujun rushed in with a happy face, "Brother Mo, our publicity effect is too good. If our Nine Lives Healing Liquid really has this effect on September 10th, no, as long as it has one-third of the effect, Danhan Pharmacy will be successful..."

Lu Jiujun's words suddenly stopped. He looked at Mo Wuji's expression, which was not happy, but even worried. Lu Jiujun's heart skipped a beat. Could it be that the new drug had failed? But wasn't Mo Wuji making one large iron bucket after another in the courtyard, and even some boilers? Could these be fake?

He wasn't sure whether the new drug was successful or not. Full publicity was also Mo Wuji's intention. Mo Wuji said that it would definitely not fail. But now...

Mo Wuji stood up, walked to Lu Jiujun's side, and patted Lu Jiujun's shoulder, "Old Lu, don't worry, there's no problem with the medicine."

"Then why do you look so worried?" Lu Jiujun heard that there was no problem with the medicine, and he was already relieved for the most part. As long as there was no problem with the medicine, everything else could be solved.

Mo Wuji sighed, "Old Lu, have you ever thought about it? Once the Nine Lives Healing Liquid is launched, it will bring us a lot of money, then someone will definitely covet it. I'm afraid we don't have the ability to protect ourselves together..."

To be honest, Mo Wuji didn't expect that his slight publicity would cause such a sensation. He didn't expect that the people here would be so eager for a healing medicine that could treat viral infections. He doubted whether he would be able to get this first pot of gold when the medicine was launched.

The penicillin process was easy to imitate, he knew, but others didn't know. In case someone secretly attacked Danhan Pharmacy before he got his first pot of gold, that would be bad.

Lu Jiujun was slightly stunned by Mo Wuji's words, and then laughed loudly, "Brother Mo, it's normal that you don't understand the system of our Chengyu Kingdom because you came from a royal family. Not to mention our Chengyu Kingdom, throughout the Stellar Transformations Empire, workshop businesses are protected, of course, on the premise that you pay a certain percentage of taxes. Back then, Danhan Pharmacy's reputation had already entered the Stellar Transformations Empire, did you see anyone dare to touch Danhan? The reason why Danhan collapsed was because I myself didn't have the ability."

Mo Wuji didn't feel relieved at all because of Lu Jiujun's words. Danhan Pharmacy's so-called strength was nothing. They couldn't even produce their own signature product. It would be strange if anyone coveted such a business. It was like a factory on Earth that used to assemble fruit phones. It looked big and had a lot of people. In fact, it was just making hard-earned money, and they still had to watch others' every move. Once they no longer needed them to assemble, that would be the next Danhan Pharmacy.

As for Lu Jiujun's saying that they were protected by the Stellar Transformations Empire, Mo Wuji was even more dismissive. With enough benefits, anything could happen. From the fact that lovers of many years could secretly plot against him, he knew that some things could not be constrained by systems and morality.

But he had to be strong, he had to make money, and there was no way to hide his strength.

Logically, even if someone wanted to seize the benefits of Danhan Pharmacy, they should start softly and then go hard. As long as he controlled the most core things, he could ask for some money and sell it later, and there would be no danger to his life.

Thinking of this, "Old Lu, let me say the ugly things first. In case someone wants to take a share, they can take my shares, but the money can't be less."

"Okay, no problem, don't worry." Lu Jiujun agreed to Mo Wuji's words almost without hesitation.

Mo Wuji sighed inwardly, but he didn't ask Lu Jiujun to sign a contract. Sometimes, if his strength wasn't enough, what was the use of even a piece of paper?

He was alone in Raozhou City, and no one would help him if something happened.

...

After discussing it with Lu Jiujun, Mo Wuji fermented penicillin day and night. In order to keep the initiative in his hands, besides collecting *qingmei* which required a lot of manpower, he did almost everything else himself. He hadn't returned to his residence for two months, and he hadn't even rested properly except for buying medicinal materials to concentrate on opening up his meridians.

Two months passed, and he finally produced a batch of penicillin solution.
