"Pretend! Didn't your lord say that the prince is looking for a precious resin? Let's collect more, maybe we'll come across it!"
At the foot of the southern mountain of Lushan Mountain, a Renaissance Army team completed the final survey of the entire Lushan Mountain.
A total of thirty-seven kinds of resin were collected.
Each resin is labeled, which area it is produced in, and which tree it grows on.
This is the job Song Yang ordered Yu Ming to do.
The spies wandered around the mountains for several months and finally surveyed the entire Lushan Mountain.
Of course, it was not just Lushan. The forests and mountains in other places in Jiangzhou, as long as there were trees, were all visited by the spies.
Even the furthest team of spies had almost reached Yuzhang.
"Let's go back to Fucheng today. After finishing the work in Lushan, we can replace them!"
The squad leader cheered up and said.
After being busy for so long, I can finally take a vacation.
Although it's not far from home, it's very frustrating to stay in the woods all day without being able to go home.
After listening to the captain's arrangement, the team members were all a little excited.
We changed carriages in De'an and loaded the collected specimens on them.
The team of investigators then galloped towards Jiangzhou.
The expressway has been opened.
The carriage can reach fifty or sixty miles.
It was still dark when we arrived in Jiangzhou.
Just in time to get off work at the Yamen Gate.
Song Yang came out of the Yamen, and the investigators' carriage happened to stop at the door.
"Young men, please pay your respects to the prince."
"Where are you on a mission?"
"Your Majesty, we are a team going to Mount Lu to collect resin."
"Resin! How's it going? How much did you find!"
When Song Yang heard that the resin team was back, he immediately wanted to see the results.
"My lord, I have collected thirty-seven species! Look, they are all on the carriage."
The team leader opened the car curtain and found thirty-seven cloth bags in the car.
"Pah!" Song Yang clapped his hands and laughed:
"Haha! So many! Good! Well done!"
Song Yang's laughter attracted the government officials who were off duty, and Fang Zhe and Yu Ming both came over.
"Your Excellency, I and others were ordered to go to Lushan Mountain to collect resin. Today, all the collection in Lushan Mountain has been completed. I am reporting to your Excellency!"
The squad leader is here to hand over a mission to Yu Ming.
"My lord, are you satisfied with these?" Yu Ming looked at Song Yang and asked.
Song Yang nodded and said with a smile: "The quantity is quite large, and they did a good job. I have to check them one by one to see if they are suitable for use."
Song Yang collected the resin, and the spies received rewards and a month's holiday.
Song Yang directly asked people to drive the carriage home, and the resin was taken directly back to the laboratory in the backyard.
Speaking of the laboratory, Song Yang plans to move into the residential building after the building is completed.
The two vacant bungalows with front and back yards will be directly renovated to make larger laboratories.
You can let Song Yang make some small inventions here.
"What good things did the prince bring back?"
Seeing Song Yang coming back with the carriage, the two girls came over.
Song Yang pointed to the carriage and smiled: "I brought a lot of resin. Whether I can get in the car in advance depends on whether there are rubber substitutes in it."
When it comes to rubber substitutes, Song Yang is very optimistic and will find the best ones and won’t insist on them if they don’t have them.
Of course, these resins are not in vain.
It's definitely useful for making plastic.
If clinker can be produced, it will provide some convenience, right?
After eating something casually in the evening, Song Yang went into the laboratory to check out the resins.
Thirty-seven samples were taken out one by one.
Then they were classified according to the type of tree.
A good look at the classification shows that there are thirty-seven samples and twenty-eight types of trees.
Song Yang picked up the resin collected from pine trees with the largest variety of resins and examined them one by one.
Four kinds of resin were collected from pine trees.
The spies are classified according to color.
At the age of 30, Song Yang discovered that these four types of resin were actually all rosin, but they were produced at different times and had different color changes.
Then I saw cypress trees, poplar trees...
After looking at various resin species, I basically get common tree species resins.
These resins were burned directly by Song Yang, filtered, put into glass jars, and then labeled for later use.
Continue to open the bag.
Only got some different resins.
Song Yang's treatment methods are similar. He first melts away the impurities, then bottles them and saves them with money.
The specifics of how to extract useful materials or develop new things will come later.
The sample was quickly opened to the last one.
This bag says, "Collected at noon on June 20th at the southernmost side of Lushan Mountain, Daqingshu."
Big green tree, a plant of the genus Ficus, Moraceae.
Also known as alpine fig, big-leaved fig, and tall fig, it is 25-30 meters high and has a diameter at breast height of 1.8 meters.
The tree from which this bag of resin was collected is an old tree, at least twenty-seven or eight meters tall.
Even though the members of the exploration team were highly skilled in climbing trees, it took a lot of effort to climb up and find some dry lumps that looked like resin.
As soon as Song Yang opened the belt, a three- to four-centimeter-long insect swooped out.
It is completely normal to have bugs in the resin tape.
When Song Yang opened the bag just now, he had crushed six small ants, four small beetles, three small caterpillars, and two moths.
But Song Yang didn't care about the bug that ran out this time, and just wanted to beat the little thing to death.
"well?"
His hand reached mid-air but stopped.
Immediately, Song Yang's expression changed, and he turned his palm into a clasp to catch the little insect.
"Is this...a lac bug?"
Song Yang held the little red worm on his fingertips and muttered to himself.
Song Yang first put the insects into the petri dish and closed the lid.
Then he immediately took out the specimens in the bag.
I watched carefully for a long time.
Then I opened the encyclopedia in my mind and compared it.
"I'll go! It's really a lac bug!"
Song Yang said with a surprise smile on his face.
Lac is a natural secretion of the lac bug.
Can be used in multiple industries.
But for Song Yang, the most important purpose is to make records!
That's right, it's a record, the kind of vinyl record played on a wind-up gramophone.
Shellac is the main raw material of records.
The principle of the gramophone is very simple, and its production is not difficult. Song Yang was confident that he could use the current technical level to produce it.
Now that we have the raw materials for the record, this set will be released.
"My lord, what is a lac bug?"
The two girls had been drinking tea in the yard just now. When they heard Song Yang's excitement, they immediately came to ask.
"Haha! This is a good thing. With Lac, I can develop my music career in the future!"
"Xiaoqian, you must like this!"
Song Yang laughed and said to Tong Qian.
Tong Qian is good at singing songs, and she would hum a few lines to Song Yang whenever she had nothing to do.
Later, when the gramophone was invented, Tong Qian could sing the songs and record them directly.
You can listen to it whenever you want.
Moreover, Song Yang can also record some pop music to give everyone a change of style.
Of course, the gramophone is also a very stylish piece of furniture!
So Song Yang decided that before the new house was completed, he must get the gramophone out!
