The bizarre phenomenon of "multiple waves" led these scientists to speculate that this thing must have become another thing in the body that was effective against bacteria. So they set out to analyze the active ingredients of "Bailang Duoxi" and decompose "amamsulfonamide".

The name sulfonamide quickly spread widely in the medical community. "Sulfadiapyridine" was produced in 937, "sulfathiazole" was produced in 1939, and "sulfadiazine" was produced in 1941...... In this way, doctors can pick and choose the drugs that are suitable for treating various infections in a "thriving" "sulfonamide family".

By Li Hao's time, the clinical application of sulfonamides had a history of several decades. It has a wide antibacterial spectrum, and the efficacy is certain, the nature is stable, the use is simple, the price is cheap, and it is convenient for long-term storage. It is a large class of drugs second only to antibiotics, especially after the synthesis of new sulfonamides and antibacterial synergists with high efficiency, long-acting and broad-spectrum, the clinical application of sulfonamides has a new and broad future.

Li Hao didn't have an in-depth study of these, but only roughly knew some synthesis processes, so he handed them over to his students to study. I just didn't expect them to get things out so quickly, and now it's ready for mass production.

Relatively speaking, the production of penicillin is not as fast as sulfonamides, so sulfonamides are used in large quantities now, and the price is not too expensive.

The ocean-going fleet has always been an important thing in Li Hao's heart, once these drugs can be applied, Li Hao will naturally give priority to using them here, of course, Datang is also slowly using these now, but the steps are not wide enough.

"Lang Jun taste this canned pineapple, this thing is so strange, it's almost like a fresh pineapple!" Chen Sanniang saw that Li Hao didn't seem to want to eat, so she immediately pricked a piece with a toothpick and sent it to Li Hao's mouth.

"This thing is what you Langjun and I asked people to make, I have already eaten it." Li Hao replied with a smile, and then took a bite of the pineapple piece handed over by Chen Sanniang and ate it in one bite, and the pineapple was also a fruit that only appeared after Li Hao came over.

"Ah, this turned out to be something made by Lang Jun, no wonder it is so magical and delicious. Is that fish sauce also Lang Jun's masterpiece, that thing tastes great when used for seasoning. Chen Sanniang couldn't help but ask curiously after hearing this.

The fish sauce she said was a kind of seasoning on the boat, and Chen Sanniang liked it after tasting it. It is often used in the seasoning of dishes, and it tastes very good, and it is really good to use it as a seasoning.

"Well, this one too. But we don't have any of that in our house. This is now run by merchants from the south, and they are doing well, and there is a slight change in taste, which is much better than the original. Li Hao nodded after hearing this, and Li Hao, who was in charge of all the canned food, sold the formula.

But there is a requirement that those merchants must follow their own hygiene specifications. Li Hao ordered the official side to conduct hygiene and quality inspections on what they made from time to time, and the people who inspected them were Li Hao's students.

In the process of inspection, if it is found that those cans do not meet the specifications, the first warning, the second direct disqualification. It will also be expelled from the chamber of commerce in the south, and all the chambers of commerce that have a good relationship with Li Hao will expel this businessman in the future.

Not only canned food, but all food is operated, except for those things that are grown by small farmers themselves. Most of them go through these procedures, and if something unexpected happens, it's the same process. Maybe it was because later generations saw too many people doing things in food, which made Li Hao hate this thing.

Fish sauce, also known as fish soy sauce, is a common condiment in Guangdong Province, Fujian Province and other places in later generations. This kind of thing can last for many years and is loved by people in these places, which is inseparable from its unique flavor, which mainly includes umami and saltiness.

However, this kind of thing is now a commonly used aquatic condiment in Fujian, Chaozhou and Qiongzhou cuisines. It is a very delicious juice obtained by pickling, fermenting and refining small fish and shrimp as raw materials, with amber color and salty taste and umami.

And with the southward trade of the Far Eastern trading bloc, this thing is now also beginning to appear in some places on this side of the South Seas. This thing is made from low-value fish, shrimp or aquatic product processing scraps, using the protease and other enzymes contained in the fish body, as well as the joint participation of a variety of microorganisms, to ferment and decompose the protein, fat and other components in the raw fish.

It is salty, extremely delicious, and nutritious, containing all the essential amino acids and taurine, as well as calcium, iodine and other minerals and vitamins. This was also an indispensable spice for the sailors of the ship's ocean-going trade, who were then taken by these people to other Tang strongholds.

"Lang Jun, are you a star in the sky? How can you know so many things?" After Chen Sanniang listened to Li Hao's words, she counted with her fingers. Proficient in medical skills, proficient in cooking, and can invent all kinds of small things to come out, fight well, and have a literary talent.

"Uh......" Li Hao was stunned for a moment after hearing this, not knowing how to answer Chen Sanniang's words. Could it be that he has crossed over from the afterlife, and he still has a bullish golden finger. Nature has all kinds of anomalies, like immortals.

"General, we have arrived at Linyi in front, and we can already see the land of Linyi above, how should we adjust?" At this moment, the signal soldier standing on the top of the ship and looking from afar ran over to deliver the message.

The ship is equipped with a lookout with special people who regularly use binoculars to observe the surroundings. There is a special commander of the navy, and when he saw the coast in the distance at this moment, he immediately sent someone over to inform Li Hao that he had to ask for instructions at this time.

"Wave the flag, get all the boats to come closer, and head to the shore!" Li Hao didn't even think about it after hearing this, so he gave such an order. "After seeing the situation on the coast clearly, we will notify the mode of operation separately, and it will be commanded by the generals of the navy, and I will only see the results."

There is a fierce battle going on on this side of the shore, but unfortunately it seems to be a one-sided situation. Only one side was attacking, and the other side was only greeting them with arrows and bombs, and there was no human figure in sight at the head of the city, and those besieging the city did not touch the city walls for a long time.

Li Hao didn't expect that his so-called stronghold would become so big after those guys ran it, it was almost like a small castle. He always thought it was just a small place, but he didn't expect that because of the use of cement, these small castles have become extremely strong, and the structure of the ring castle is also referenced.

It's no wonder that some people in the imperial court here are seriously dissatisfied with this, this is simply a small country within a country. Those Linyi people are not stupid, how can they tolerate the existence of these things, and it is strange if they don't resist.

Because of the existence of the small castle, and the people on Lin Yi's side have no experience in attacking fortifications at all, in the face of such a castle, they have been attacking for two months, and they have not brought any damage to the castle. So when Li Hao and the others came over, they saw such a strange scene.

"Let the gunboats prepare, put a few rounds along the coast." Seeing that there was no problem with the stronghold here, Li Hao didn't bother to pay attention to the war here. To be honest, this level of war is too child's play, so he has no problem with the orders of the generals of the navy.

After listening to the words of the naval general, the communicator on the ship immediately waved flags with the surrounding ships. All the gunboats sailed out as soon as they received the flag, and then marched in unison, using their bow guns to launch the first round of attacks on the Linyi soldiers who were attacking the stronghold.

The order given by the generals of the navy army was to put a few rounds, obviously they overestimated the combat effectiveness of those Linyi soldiers. Not to mention a few rounds, after one round, there was no longer a single soldier standing and moving on that battlefield, and the entire battlefield was empty.

Except for those who were killed by the explosion, or those who were injured and scared stupid, all the other active brains ran away, and there was no one left, and the surrounding area was empty. The general who commanded the battle looked a little incredulous when he saw that the battle was over so quickly, but the enemy on the shore was gone, so he immediately sent someone to contact the stronghold.

Soon, all the results were summarized in Li Hao's hands, and the stronghold here was not damaged, and there were enough materials in reserve. Even if Li Hao and the others don't come, they can hold on for half a year or more with the small castle and the stored materials here.

This was already prepared according to Li Hao's request when the imperial court had not come to Linyi's side to reprimand, so as soon as the two sides broke off diplomatic relations, this stronghold sealed off the castle and was always vigilant against the attack of the Linyi court.

"Refill the stronghold, and we'll go to the next stronghold!" After reading the battle report, Li immediately asked his fleet to prepare the next stronghold. For him, logging in is not the point right now, the point is to support all the strongholds.

Don't let any accidents happen in these strongholds, and don't let the people in these strongholds suffer too many casualties. As long as these strongholds have always existed, Li Hao can log in whenever he wants. However, to Li Hao's surprise, the next encounter of his fleet was exactly the same as the encounter at the first stronghold, and they had not experienced any contact combat at all.

Almost all of the besieging Linyi soldiers released the pigeons after a round of artillery fire, and even the officials who commanded them turned around and ran away one by one, and the entire fleet of people in such a war wondered, it seemed too easy. It didn't feel like they were fighting, and those Lin Yi were scared and ran away.

"These people's armies are so useless, why are they going against Datang? It's just hilarious! ”

Regarding the performance of these Linyi people, Chen Sanniang was also curious. This kind of combat effectiveness is not even as good as the people of Shanyue that she once led, and the leader of such a place can still cut the land and claim the king, which is too child's play.
