"A hundred tons? How many mortars are you going to build? A cannon barrel is only a few tens of kilograms, you are lighter, it is estimated that you have to build thousands of guns for 100 tons, where do you let the 29th Army get shells? Wang Chuanming exclaimed.

"I didn't say that they were all given to them, the front-line troops could give it! Of course, the premise is that they can't run away when they see the Japanese like the Northeast Army, and I am also going to sell them, such as the Taiyuan Arsenal and the Jinling Arsenal, which can be sold, and I think a hundred tons is still a little less, and if it sells well, I am ready to continue to do it. Yang Feng said proudly that he was happy to imagine the flood of mortars in the Chinese army.

"Do you think the steel mill you're going to open can make this thing?" Wang Chuanming asked.

"It's hard to say, I can't guarantee a level like this, but it's okay to be a little worse than it." Yang Feng thought to himself that high-pressure alloy steel is a relatively high-end technology in modern times, how can you let me let a little white man guarantee you.

Wang Chuanming did not speak again.

Yang Feng left the steel pipe, and then, with the help of Liu Haining, found a more reassuring lawyer, and he acted as an agent to issue patent applications for sulfonamides to European and American countries at the same time, of course, this is only a necessary process, and whether the real patent can be won still requires behind-the-scenes action.

"Mr. Richard, is Pfizer interested in producing sulfonamides?" In the French restaurant of the Six Nations Hotel, Yang Feng choked Richard, who was chewing steak, with a sentence.

"Yang, Mr. Yang, are you saying that Yanhuang Laboratory has solved the production problem?" He asked cautiously with a look of being hit by gold.

"It's going to be soon, but I'm applying for a patent in your country and Europe right now, and even if I do have to put it into production, I'll have to wait until I get the patent." Yang Feng said reservedly.

Richard was very smart and immediately understood Yang Feng's intentions: "You mean, if Pfizer can facilitate your application as soon as possible, you will cooperate with Pfizer?" ”

"Suffice it to say, with our friendship, will I still go to work with Bayer, Novartis, SmithKline, Eli Lil?" Yang Feng said with a smile.

Richard immediately laughed, smiling like a well-behaved puppy: "Of course, Mr. Yang, how can they compare to our friendship." ”

"So, I just sent out the patent application, and I came to you immediately, and our laboratory is still conducting more in-depth research on sulfonamides, and there may be more types, and if we have a good cooperation, Pfizer will definitely be the first choice."

Yang Feng now sells only one sulfonamide, that is, the most common compound chloroxazole, that is, sulfamethoxazole, and he plans to launch other sulfonamides one by one.

The Germans synthesized Bailang Duo in 32 years, and then Dumac began to study its medicinal value, out of German rigor, until 35 years he went through a test again and again, even including using his seriously ill daughter to do a test, and finally publicly published his conclusions, and then Bailang Duo Xi was gradually used by the hospital, and finally became famous in one fell swoop after 36 years because of the cure of Roosevelt's son.

In fact, Bailang Duoxi is not sulfonamide, or its Chinese chemical name is called p-aminobenzene sulfonamide, the product of Bailang Duoxin in the human body is, this is later found by scientists from the patient's urine after taking Bailang Duoxin, and Yang Feng sells real synthetic sulfonamide, and Bailang Duoxi is not related to anything, as for the name is a Chinese abbreviation, if you can infer its composition from such a abbreviation, it is simply more terrifying.

Therefore, Yang Feng is not worried about the problem of more than one hundred waves.

Richard sat there, his eyes rolling, carefully considering the business.

At first, Pfizer knew about sulfonamides, but he was informed by an American doctor in Beiping, who used all the words he could know to explain the magic of sulfonamides to Pfizer, which prompted him to come to Beiping.

After coming here, he immediately went to major hospitals to investigate, and the magic of sulfonamide was really displayed in front of him, which prompted him to accept Yang Feng's terrifying price.

To be honest, Pfizer does want to produce sulfonamides through research, but Richard is also very clear that it will take time, a long time, but Yang Feng can't give them time, just like he said himself, once he releases the news of looking for collaborators, countless pharmaceutical companies will flock to him, no matter who gets this cake, it will be a heavy blow to Pfizer.

Richard made his decision in an instant.

"Cheers to our friendship!" He raised his glass with a smile on his face.

Of course, this is only a cooperation intention, and whether to really agree to cooperate with Yang Feng will have to be decided by the board of directors of Pfizer, but this is only a matter of time.

Solving the sulfonamide patent problem, Yang Feng was in a very happy mood, but as soon as he returned to the Little Red Mansion, his mood was immediately unhappy, and the haunting Ito was waiting for him.

"Ah, Ito-kun, you see that I forgot it when I got busy, this is your medicine." Yang Feng pointed to the two boxes of domestic viagra and said.

Ito looked at these two small cardboard boxes with greedy eyes, the happiness of these days was like a dream, he never thought that he could still be so strong as a man, and when he thought of the madness that he galloped on a woman when he took the little blue medicine, he couldn't help but feel a feeling of tears in his eyes.

Fifteen minutes! Fifteen minutes!

Forty-five years, he waited for this moment for forty-five years, and after doing it for the first time, he even looked up to the sky with excitement.

"But Mr. Ito, what do I want?" Yang Feng's words woke him up.

Ito's face immediately turned to extreme frustration.

"Mr. Yang, I'm really sorry, I'm here to apologize to you this time, the merchant ship Aduo Maru, which transported ginseng from Anton, was wrecked and sank outside the mouth of Dagu!" He said with a bow.

"Huh?" Yang Feng suddenly remembered the ship that was sunk by himself, and the expression on his face suddenly became very exciting.

"Then I'm sorry, I have to wait for your second batch of ginseng to arrive, and I can give you the medicine." He said helplessly.

"Mr. Yang, can I exchange antiques with you?" Ito said that he had already sent a sample to the headquarters in Japan, and the big boss, who had personally tested the results, was madly urging him to get the medicine back, and if he delayed any longer, he didn't know how much anger he would have to bear.

"Antiques, I still have a batch in my hand now, and besides, this thing can't be sold for any price now!" Yang Feng said with an embarrassed face.

"Otherwise, you bring the things, and then we will find someone to estimate the value, and add 50% to the price of the medicine, after all, I am not a collector, and it is difficult to say whether I will lose some of it if I resell it." Yang Feng said.
