The railway was built from Zhongcheng to Chang'an, and as in previous partnerships, Wang Haoran also did not invest much in the construction of the railway, with rails, cement, gravel, sleepers, etc. all produced by his own factory. Since the start of construction of pen ~ fun ~ pavilion www.biquge.info Wang Haoran has gone to the construction site every day to check the situation, and he does not dare to relax in the slightest before the workers are familiar with the process and precautions.

One day, when Wang Haoran came back from the construction site, he happened to see Xie Changfu talking to two strange farmers outside the door.

"The little master is back!" Xie Changfu saw Wang Haoran and greeted him.

"What is this?" Wang Haoran looked at the two farmers and asked.

"These two people said that they were from Yonglu Village, Jingzhou, and they also said that they would give you something." Xie Changfu called the two farmers over and said to them: "This is our little master, if there is anything, you can tell the little master by yourself." ”

"The grass people meet the little master!" The two peasants looked at a loss, and felt that the nobleman should kneel, so they were ready to kneel.

"You don't have to be polite, if you have anything to do with me, just say it."

The second farmer breathed a sigh of relief when he saw that the little young master was so easy to speak, and the older farmer took out a small bag from his arms, opened the bag and took out a small white thing from it and handed it to Wang Haoran and said: "Little young master, this thing was discovered by the people in our village by accident, we saw that this thing was strange, and we thought that the little young master knew astronomy and geography, and even the stones in the ground could be turned into coal, so we brought it to the little master to see if this little thing was useful to the little master." ”

Wang Haoran took the little white thing, this thing was very light, and it felt a little hard when he pinched it, he broke it again, and his eyes suddenly lit up! This...... How does this thing feel like the plastic of the afterlife?!

"How did you get that?" Wang Haoran asked curiously.

"This is resin taken out of a tree, and it used to be taken out by children in our village to play with, but I didn't expect it to become like this after a long time." Seeing that Wang Haoran was very interested, the old farmer suddenly became energetic, it seemed that the purpose of this visit was promising, and he seemed very excited when he spoke, pointing to the young man who came with him and continued, "But it turns out that there are too many pieces of wood, and this one was made by pressing out the resin." ”

"Resin?!" Wang Haoran was even more puzzled, as far as he knew, there were no rubber trees in Datang at this time, and the rubber trees were still in distant South America! "What kind of tree is that? What does it look like? ”

"The people in our village call this tree a brittle branch, and the grass people have brought some with them." As he spoke, the old farmer took the sack that the young man had brought.

"Brittle branches?" Wang Haoran had never heard of the name of this tree, it must be just a local name, thinking that this matter was very important, and it was not appropriate to say more outside, so he beckoned the two farmers and said, "Let's go, let's go in." ”

When the people came to the hall, the old farmer took out the contents of the sack, and there were branches, and a sawn trunk.

"Isn't this the Eucommia tree?" Xie Changfu on the side recognized the tree at a glance.

"Eucommia tree?" Wang Haoran felt that the name was somewhat familiar.

"That's right, this is the eucommia tree." Xie Changfu picked a leaf and sniffed it and confirmed, "The bark of this tree is a good medicinal herb, and it is sold in the medicine shops outside." ”

The two farmers felt embarrassed and disappointed when they heard that the brittle branches were so commonly used, and that the people of the city knew more about the tree than they did.

Eucommia? Medicine? As soon as these two words were linked, Wang Haoran finally remembered the story he heard about a man named Eucommia who went up the mountain to collect medicine, but this Eucommia ulmoides tree made of medicinal materials can still make plastic? This Wang Haoran has never heard of it.

Wang Haoran was thinking, since this tree is well-known, there should be no way to make plastic, right? Otherwise, why did he only hear of rubber in later generations, but not the word eucommia gum? I've heard of Eucommia capsules. But the properties of this resin are really too similar to plastic, Wang Haoran decided to take these to do experiments first, in case he missed something that could be made into plastic because he didn't have enough knowledge, it would be ridiculous and generous.

"Two, you have come from afar, let's stay here for a few days for the time being, whether this thing is useful or not, I still need to study it before I can make a conclusion."

"Okay, well, listen to the arrangement of the young master."

"Fauber, you wait and take the copper money to these two." Wang Haoran said to the two farmers again, "I'm afraid you rarely come to Midtown, right?" If you're bored these days, you can take a stroll around and see the excitement. ”

"Thank you, young master!"

The two farmers didn't show much excitement, presumably there were other things on their minds, but they didn't say it themselves, and Wang Haoran didn't bother to ask, his mind was full of questions about whether eucommia resin could be made into plastic, and he couldn't wait to do an experiment now.

Early the next morning, Wang Haoran and Chen Jun went to the Zhongcheng Research Institute together, and naturally took a human-powered rail car. This human-powered rail car has hardly stopped since it was opened, because there are many rich children who like to ask a few friends to ride on it for sightseeing and fun, and there is only one track, and some people who need to be in a hurry are easy to be blocked behind by the slow traffic for sightseeing, causing traffic jams. During that time, maybe there will be something like this in Midtown: Sorry, I'm late, there's a traffic jam on the road.

In order to solve this problem, Wang Haoran investigated the specific situation and found that there were many more people sightseeing on the rickshaw than he imagined, so he simply paved another sightseeing track route, which not only passed through the most prosperous area of Zhongcheng, but also passed through the beautiful woods and the mighty Yellow River...... That's right, Wang Haoran has the idea of making Midtown the best tourist city. Wang Haoran believes that in a few years, when Zhongcheng has the nature of a tourist attraction, the people who live with each passing day will have no worries about food and clothing, and have a small amount of savings, which will definitely drive the tourism industry, and at that time, Zhongcheng will become the leader of the tourism industry.

In addition to this, the current problem of rail car congestion can only be solved by limiting the minimum speed.

When he arrived at the research institute, Wang Haoran asked Chen Jun to put down the affairs in his hand and help him. This experiment is also simple, that is, the procedure is more cumbersome, such as the preparation of lye and acid, and the concentration is prepared from low to high for experiments, and if it is low, it will be thickened, and so on.

Until the third day, Wang Haoran took out the condensed eucommia resin, pressed it a few times with a small wooden stick, and then laughed. He picked up the small piece of eucommia resin and broke it with his hand, and the elasticity was similar to that of the later generations of Youli gum! In fact, yesterday Wang Haoran was able to make such an elastic Eucommia ulmoides resin, because at that time he found that the elasticity of the made Eucommia ulmoides resin could be controlled by changing the concentration of lye and acid.

Therefore, compared to Wang Haoran, Chen Jun was even more excited. Holding this magical thing, Chen Jun was even more enthusiastic, and said, "I'll try to increase the concentration again." ”

Wang Haoran waved his hand to stop it, and said: "Although we are researchers, my purpose is not to study all new things thoroughly, but to open people's eyes through this new thing, so that more people are willing to spend financial resources and manpower to study more things." And our research is not perfect, as long as it is enough for our own use, why not leave some defects for others to make up? ”
