"Teacher Ma, what do you think I brought back? Lei Jizi said that this is a fat field stone. Yang Bo was still used to calling Teacher Ma, and when he returned to the stone temple, he woke up Daoist Ma and shouted excitedly.

Ma Daochang opened his eyes and saw Yang Bo holding a puppy in his arms, his old face suddenly darkened, and he frowned and scolded: "Everything is demoralized." ”

During this period, the livelihood of the Ming Dynasty withered, and ordinary people at most raised dogs to take care of their homes, like Yang Bo wearing silk robes and holding a puppy in his arms, that was a standard image of a gentleman, Ma Daochang scolded reasonably.

Yang Bo handed the stone in his hand to Ma Daochang, who had already sat up, and said proudly: "I have seen on the Internet, this Feitian stone is a kind of phosphate rock, don't just care about scolding, you better take a look first." ”

Ma Daochang took the stone, weighed it in his hand, sniffed it with his nose, and asked: "It is indeed a fertile field stone, and it is a high-grade phosphate rock." What do you want? ”

"What? Make matches, you're a chemistry professor, you know this better than I do. Yang Bo said urgently.

Ma Daochang glanced at Yang Bo deeply, removed his legs from the sitting, put on his shoes with great difficulty, stood up with a painful face, and said lightly: "Let's go, I'll take you to see something." ”

It seems that the two months of life at sea have tormented him a lot, Ma Daochang walked in front, and he became more and more faltering, Yang Bo was afraid that he would accidentally fall, so he stepped out to help.

"Whether it's white phosphorus or red phosphorus, it's not difficult to get a pound and a half pound in the laboratory, but if you want to produce it industrially, I'm afraid it's even more difficult than climbing to the sky, you have to be mentally prepared."

Yang Bo looked overjoyed and asked, "Teacher Ma, could it be that you can already make white phosphorus and red phosphorus?" Ma Daochang walked straight forward, without looking at Yang Bo, and said, "I have done more than that. ”

The two of them came out of the back door of the stone temple, and Yang Bo saw that at the foot of the mountain, there was an independent small house, and a simple shed was built in front of the house.

"These people are making alcohol, which is not very technical, and the alcohol produced is only for the stone temple's own use, so I don't look at it. You help me there...", Ma Dao said, pointing to a door in the small house behind the shed.

They walked to a door on the right-hand side, Ma Daochang opened the lock, and Yang Bo followed in, and when he saw the furnishings in the house, Yang Bo froze.

On the left is a row of wooden shelves filled with jars and jars, and on the right there are several stoves.

"I've been in Shenjiabao for six years, so I naturally know that the West Mountain is full of fertile stones. What you thought, why haven't I thought of it? ”

Ma Daochang stopped in front of a half-human-high furnace in the innermost part and said, "This is a furnace for copper smelting, which can pull fine copper wires, and the copper wires are wound for DC generators. ”

When Yang Bo heard this, he was taken aback, can he still be a generator in this era? But then I thought that later generations of junior high school students could make a generator with their own hands, they used artificial magnets, although there are no artificial magnets now, but natural magnets are not difficult to find, and it is theoretically possible to make a generator.

"This is a furnace for glass, and I was going to make some test-tube beakers or something, and my plan was to build a chemistry lab. But great difficulties were encountered. As you can imagine, it is not difficult to make molten glass, but it is difficult to blow glassware of various shapes. ”

It is said that more than 1,000 years ago in the West, someone had inadvertently fired glass, and there were also glass workshops in the East, and glass is essentially colored glass containing impurities. Making glass at the current level of industry is in fact already happening.

Yang Bo saw a pile of discarded glass stubble in the sink under the glass stove, which could vaguely be seen to be test tubes and beakers, but the thickness was uneven and crooked, obviously unusable.

And some glass beads? Yang Bo stretched out his hand and scooped up a few carefully, but they were not round enough, there were bubble impurities, and the transparency was not enough.

On the wooden shelves against the wall, I saw a few glass containers, but more of them were clay pots, and it is estimated that the yield of blown glass containers is too low.

"This is a hand-cranked DC generator. With a generator, it is possible to electrolyze brine to produce caustic soda. Soda ash is then obtained. With soda ash, glass can be made. With glass, a chemical laboratory can be built, so that phosphate rock can be analyzed, and these are all preparations before making matches. ”

Yang Bo remembered that in later generations, soda ash was used to prepare caustic soda, but now Ma Daochang uses caustic soda to make soda ash, which is obviously limited by the industrial level conditions of this era.

The size of these stoves of Ma Daochang is very limited, and the crucible used is no more than the size of a sock, Yang Bo couldn't help but show a disappointed look when he saw this.

Ma Daochang ignored it, motioned to Yang Bo to help him out, and the two walked out of the room, Ma Daochang instructed Yang Bo to lock the door, and introduced Yang Bo all the way, Ma Daochang was already physically exhausted. He sat down on a doorway pier to catch his breath, beckoned Yang Bo to sit down as well, and stared at Yang Bo intently for a long time before speaking.

"Although you are born with a talent, you are frivolous and extremely imprudent, except for a good hand of chess, you are useless..."

When Yang Bo heard this, he looked displeased, raised his hands, and said dissatisfiedly: "Teacher Ma, Teacher Ma, I know that I skipped a lot of classes when I went to school, and I am not so unbearable." ”

Ma Daochang raised his eyes to the sky, stroked his beard, and said to himself: "I told you that my physical body Ma Yizhen is indeed a person in history. ”

Yang Bo remembered that Ma Daochang told him on the boat that this horse was a needle, a famous magic stick in the late Ming Dynasty, known as more than 300 years old, known for 300 years and 300 years later. He once traveled to the military front line of Liaodong and Shandong, but many important ministers of the Ming Dynasty, such as Shanhaiguan Guan Xian Liang Tingdong, Liaodong Governor Yuan Chonghuan, and Dengzhou Governor Sun Yuanhua have intersected.

In Yang Bo's view, if you can live to be 300 years old, you will naturally know 300 years in advance. Three hundred years later? It's nonsense, it can be predicted in advance, and it is in vain not to intervene, if you intervene, how can you predict accurately? It's a paradox. Yang Bo didn't believe it.

“... According to historical records, someone saw Ma Yizhen sitting in a canoe and sailing east to the vast sea alone, and he didn't know what happened. That day is tomorrow. Ma Dao's eyebrows were full of sorrow, and he said weakly.

Tomorrow, the 14th day of July in the first year of Chongzhen.

But what does this mean? It's just a folk legend, just a false rumor, Yang Bo looked at the lonely Ma Daochang, and thought to himself, it seems that the god stick Ma Yizhen has seriously interfered with Mr. Ma's thoughts, can this be believed?

Yang Bo said disappreciably: "These are feudal superstitions, you are Teacher Ma, not Ma Yizhen." ”

"This is the spare key in my room, you take it, in case something happens to me tomorrow...."

"Okay, Mr. Ma.." Yang Bo took the key, helped Ma Dao Chang, and said with a smile: "You are in good health, you are just too tired, come, I will help you back to the house to rest." ”

Lying in bed at night, thinking about what Ma Daochang had said during the day, Yang Bo tossed and turned, unable to sleep. In order to make matches, Ma Daochang can be said to have worked hard, and the orderly progress of one ring after another, which took six years, and he only made some samples in the 'laboratory'.

This 'laboratory' is simply a gold hole, and for these samples, Ma Daochang invested all the income from treating diseases and saving people. But Yang Bo is nameless, what he wants is a cash cow.

According to Ma Daochang's plan, it is rigorous, but Yang Bo can't wait, don't get the match that hasn't been made, the wild boar skin will come in first, and when the time comes, he won't earn the silver, and he will also put his life in, isn't it sad to rush in.....
