With the publication of the advertisement published in the "New News of the Special Zone", it immediately caused a warm response. Over the past year, Mao Geng made his fortune at an unprecedented speed. It was only a matter of time before he became the richest man in the Song Dynasty. What did Mao Geng rely on? He relied on exclusive new technologies. These technologies were Mao Geng's treasure pot. If he could buy Mao's technology, he would master the key to getting rich quickly.

The temporary office space for technology transfer is located in this community with Su Zhiyan's residence, and the model house is directly occupied by the office. During the day, it is the office building for technology transfer, and at night it is still used as a model building, but the customer groups received during the day and night are not consistent. Of course, there are also those who want to buy both technology and building, which is another matter.

Some businesses stationed in the Special Administrative Region took the lead, but they only spent money to buy some technical introduction materials, so they could only buy a technical introduction for a consistent amount. Of course, irrelevant personnel would not spend this in vain. The reason for collecting money is to save the thought of If You Are the One.

Only after five days will the technology transfer be discussed in detail. According to Wu Yixin, this is to ensure fairness. After all, technology transfer cannot be carried out on a first come first served basis.

Although it costs money and costs a few pages of paper, hundreds of copies were bought in one morning.

The sales information here are very lively. At this moment, Mao Geng accompanied Zhao Han on a ship under construction and commented on the ship that was almost about to be completed.

The newly built ship is the iron ship mentioned by Zhao Han. However, this is suspected of a change of concept, because the main body of this iron ship is still a wooden ship, but it is just above the waterline and a layer of iron will be laid.

The ship started construction three months ago. In addition to the improvements on the bow, it adopts an external floating shape. The rest are built intact according to traditional ships in the Song Dynasty. The key change is on the surface of the ship.

This era has not yet entered the artillery era, and it will be only available to the Song Dynasty for the time being. For wooden ships, the most feared thing is the enemy's fire attack. Yu Yunwen, the navy commanding the Song Dynasty, defeated the Jin navy on the Yangtze River, and used the fire attack weapon such as iron cannons. The catapult threw iron cannons, and the explosion destructive power was negligible, but the fire attack power of the iron cannons was enough to burn the warships, and the Jin navy was defeated.

Therefore, Mao Geng took great pains to consider how to prevent fire attack. Obviously, a layer of iron sheet is not enough to prevent fire. In this era, tin oil has been used as a fire attack weapon - tin oil is oil. How can a thin layer of iron sheet withstand the ablation of the fire caused by tin oil? Needless to say, it will be burned through soon and then the wood below will be ignited. Therefore, a simple layer of iron sheet cannot resist fire attack.

To this end, Mao Geng designed a layer of barbed wire and cement fireproof layer on the outside of the wooden hull. The barbed wire and nailed it to the hull, and then applied a layer of three-centimeter fine sand concrete mortar. In this way, it not only has the tough and impact resistance of the wooden boat, but also has the fireproof effect of the cement boat. Then it is pasted with a layer of iron sheet on it. Hehe, and the armor effect of the iron boat. It really has whatever you want, it can be called the most powerful warship of this era.

The cement has almost hardened, and today we can finally lay the first sheet of iron.

When I walked on the deck, I saw long strips of lattices drawn on the cement deck, and the iron sheet will be nailed to the deck according to these lattices. There are exposed wooden pillars on the four corners of the lattices and the midpoints on each side. These wooden pillars are used to nail the iron sheet.

A worker first laid a layer of asphalt in two adjacent squares, which was used as a buffer layer. Then two workers laying iron sheets stepped forward, one holding a galvanized iron sheet in hand. The iron sheet was long, forty cm, and one meter long. This was rolled out by the first generation of rolling mills. The four sides of the iron sheet were stamped and four narrow sides of 1.5 cm were punched down. These four narrow sides were five millimeters lower than the entire iron sheet plane. There were holes on the edge strips. Put the narrow sides of the two iron strips together. After they were put together, press a three-mm thick iron strip on the concave narrow sides between the two plates, and then nailed the nails through the pre-made holes. The two buckled iron sheets were fixed to the deck.

After nailing the four boards, Mao Geng asked Zhao Han to stand up and try it. The two of them stepped onto the iron deck and felt very down-to-earth. After carefulness, they felt a little elastic under their feet. Zhao Han felt a little satisfied and said happily:

"Not bad! I like this iron deck very much. I guess our Song Dynasty sailors will not be seriously injured if they fall on it."

Damn! This is how I understand it! Mao Geng thought to himself, is this the solid bullet I have to deal with in the future that the enemy is going to fight?

In short, Zhao Han is as good as he is satisfied. Nowadays, steel resources are limited. Zhao Han wants to build an iron ship. This is the iron ship built by Mao Geng for Zhao Han. Anyway, it is wrapped in a layer of iron sheet, so it is barely reasonable to call it an iron ship.

In Mao Geng's mind, this kind of iron-packed ship was weak, but everything had a process and could only be gradually progressed. According to Mao Geng's plan, he would first build such iron-packed warships, and then build a dome-clad ship based on a wooden hull, and finally build an iron-clad ship. Mao Geng would not choose to make a big move, because the times were not urgent. If he really wanted to build an iron-clad ship, both steel and construction technology needed a reserve process.

After wrapping the iron sheet and outfitting, the boat is really completed, and I’m afraid it will take you to go after the New Year. After the New Year, it’s after the New Year, and there’s no need to grab time.

Getting off the boat, Mao Geng and Zhao Han boarded another boat. Unlike the iron boat, this was designed by Mao Geng based on a flying scissors sailing ship in the 19th century. It uses a hollow bow with a length-to-width ratio of six to one. It looks thin and thin, and the superstructure on the boat will be simplified to the extreme. Given that the hull is far less round and full than the traditional sea boats of the Song Dynasty, Zhao Han didn't like the style of this boat. However, when Mao Geng heard that this kind of boat would run very quickly, Zhao Han was a little confused, but Mao Geng was always magical. He said that if he ran fast, maybe he really wouldn't run slowly.

After looking around on the boat, the deck construction had just begun and the workload was still quite good. Since the focus was on ensuring the construction of the iron boat, the scissors were not paid enough attention. Even if you hurry up, the completion date would be at least after the Lantern Festival.

It’s like this that shipbuilding is so urgent that it can’t be rushed. Maybe after the ship is launched, it will be faster in the future.

In fact, Mao Geng didn't need to worry too much about shipbuilding. With Zhao Han staring at him, Jiang Ang was also very good at doing things. Mao Geng just asked occasionally. For example, this is the first time today, Mao Geng was worried, so he came to take a look. Most of the time, Mao Geng basically only paid a little attention to the progress of shipbuilding and controlled it at the technical nodes. At other times, Zhao Han and Jiang Ang were allowed to tinker with.

After leaving the shipyard, Mao Geng came to the medical laboratory.

This laboratory has been open for a while, and Doctor Yu and Huang Zaixin are in charge of this laboratory. Doctor Yu is the leading doctor of the Special Administrative Region Hospital and has not had much time in this laboratory, so most of the time Huang Zaixin works in the laboratory with two assistants.

Today, Mao Geng sent someone a simple microscope. Mao Geng came to take a look and taught Huang Zaixin how to use this baby microscope.

Huang Zaixin indeed regarded the microscope as a treasure. After sending it here today, he presented it with the microscope like a magic object, and he didn't even dare to touch it.

Mao Geng smiled, and then began to teach Huang Zaixin how to use a microscope.

When Huang Zaixin saw a small ant enlarged into a big ant in the microscope, he was surprised and then Mao Geng dripped a drop of water with a piece of glass to let Huang Zaixin watch the bacteria in the water move.

"Did you see it? The moving things in the water."

After a while, Huang Zaixin took his eyes away from the microscope and replied:

"Well, there is something moving. There are actually such things that can move in a drop of water. What are they?"

"Oh, that's bacteria. If you see too much in the future, you will gradually understand."

"Then, what's the use of this microscope? What are the benefits of seeing these small bacteria clearly for our medicine?"

Mao Geng couldn't tell Huang Zaixin for a moment. When he saw the mice used for experiments in the cage over there running, he smiled and said:

"Master Huang, haven't you used mice to do drug tests before? Now it seems that you are already familiar with it! This is also the case with a microscope. The more you go, the more you become more and more comfortable."

"I hope so!" Huang Zai said confidently that using mice to perform pharmacological experiments on drugs is really rewarding. I hope that this can be done after using this microscope.

When Mao Geng saw Huang Zaixin nodding, he asked with a smile:

"After Master Huang came here, he collected a lot of medicinal materials. I wonder what good medicinal materials he has collected recently?"

"Well, I'm going to hide it from Chief Executive Mao. I collected a good medicine today. I didn't expect that there was a purple grass here, and this medicine looked really good." The pharmacist was in a good mood when he encountered the excellent medicinal herbs. Seeing Huang Zaixin's joyful look, one can imagine that he had found a treasure.

But Mao Geng suddenly remembered something in his mind and immediately asked:

"You mean cypress? Also called lac and erygum, right?"

"Not bad! That's right. I didn't expect Chief Executive Mao had a dabbling in medicinal materials, which is really admirable!"

What a fart! This is just a middle school classmate in his previous life who later went to a mountainous county to become the deputy county magistrate in charge of agriculture. He worked all day long to develop the mountainous economy. When he was together, he couldn't help but brag about what specialties he had under his control. When his brother bragged once, he talked about the successful introduction of Taiwanese green jujube trees to produce green glue and ecological glue. So Mao Geng knew that there was actually a kind of insect that spit out natural glue in the world - lactoworm!

Pelaginia survives by absorbing the sap of parasitic trees. It secretes purple natural resin, also known as lac, ereg, and purpura. Shellagin is not only a traditional Chinese medicine, but its history as a traditional Chinese medicine can be traced back to the Han Dynasty. It is also a powerful adhesive resin. Pelaginia resin has strong adhesion, toughness, good luster, and has thermoplasticity and thermosetting, oil-resistant, acid-resistant, non-toxic and irritating to people. It can be used as varnishes, polishers, adhesives, insulating materials and mold casting materials, etc., national defense, electrical, coatings, rubber, plastics, medicine, leather, papermaking, printing, and food industries. It is used by almost no industrial department.

Shellocs also produce wax - Shellocs wax, also known as shellac wax, is a yellow hard natural wax with high hardness and good luster. It can be used as a polishing agent, such as adding it to shoe polish. In addition, pigments can also be separated from shellac. Shellocs are a bright red non-toxic powder that can be used as a green edible red pigment.

Don’t say that during this period, Mao Geng’s mind was either this glue or that glue. Gelatin was used for cod liver oil, gelatin and vegetable glue were used for buttons, and compound glue for tires was the highest requirement. Mao Geng always hoped to find a good glue that can further improve the performance of the compound glue after adding it.

Regarding plant glue, Mao Geng has successfully extracted konjac glue before, but the konjac glue is not strong enough. Therefore, Mao Geng also plans to collect Tianjing and prepare to extract Tianjing glue, but so far there is no time to try it.

Now! This natural shellac is a good thing. It seems that even if you make bullets, you can use it. I never thought that there will be one in Taiwan!
