Zhu Cijiong is still very satisfied with the results seen during this visit, in fact, the current technical foundation of the Ming Dynasty, can be used gasoline, kerosene, diesel, lubricating oil, paraffin wax and asphalt, and other things, which are too far away, and the Ming Dynasty does not have the foundation for petrochemical industry now.

That is to say, now Song Yingxing's research work on petroleum refining has actually achieved phased success, as long as the diesel, lubricating oil and paraffin are separated and purified, as for the rest, Daming does not need it very much at this stage, and there is no need to rush for a while.

Song Yingxing has achieved such a great result, it is time to cash in the reward, Zhu Cijiong considered the amount of the reward while walking towards the steps leading to the seventh floor.

He thought that the seventh floor was the office space, because almost all the refinements that should be seen had been seen, and no matter how many they were, he thought that Song Yingxing would not be able to refine them at this stage.

As a result, when he came to the seventh floor, he saw that it was not an office area, but there was still a separate room in the middle, but this single room looked more square, without the strange shape of the first six floors, and there seemed to be nothing else around except for the storage room.

Zhu Cijiong couldn't help but walk to the middle room curiously, this time there was no one on duty at the door, and Song Yingxing did not dissuade him, he went in smoothly.

When he went in, he was a little dumbfounded, there was a huge iron trough in the room, and the same huge iron pipe led to the bottom, and then, there was nothing.

At this time, two guards were carrying barrels of oil into the iron tank.

It turns out that this is a place to add ingredients, what is there to see!

However, it seemed that it would be a little embarrassing to turn back like this, he thought about it, pretended to be curious and asked, "Chang Geng, why is it such a big slot?" “

When Song Yingxing heard this, he hurriedly explained: "Back to the emperor, it's like this, because this oil is too sticky, and the amount of each barrel is not accurate, and the amount of pouring down is not easy to calculate, so Weichen made such a slot, as long as it reaches the scale inside, it can almost fill the oil storage tank below." This also has the advantage that you can prepare in advance here, once the sixth layer is refined, and the remaining materials have flowed to the fifth layer, as long as the valve is opened here, the sixth layer is slowly filled, and there is no delay at all. “

Zhu Cijiong only realized at this time that there seems to be no such thing as a circulating pump at this time, no wonder Song Yingxing wants to build the experimental field on a hill, if it is built on flat ground, the oil in it will not flow at all!

This Song Yingxing is really talented, without a circulating pump, he can actually think of using the height difference to let the oil flow down layer by layer, in order to achieve the purpose of step-by-step refining, smart, really smart.

Zhu Cijiong is more and more satisfied with Song Yingxing's talent, when the reward mechanism has not been established before, he has made a lot of contributions to the Ming Dynasty, he has contributed to the research and development of the original machine tool and the new machine tool, and the locomotive is also developed by him, he has made so many contributions, but has not received any substantial rewards, so it will definitely not work.

Zhu Cijiong decided, this time he must reward Song Yingxing well.

These seven-layer additives are not good-looking, Zhu Cijiong pretended to turn around and took the lead to the steps leading to the eighth floor.

The eighth floor is the real office area, the ground is all plastered flat with cement, and the entire eighth floor is no longer a big house in the middle, empty all around, but a corridor in the middle, with many single rooms separated on both sides.

Under the guidance of Song Yingxing, Zhu Cijiong slowly walked down the corridor, probably for the sake of ventilation, the rooms on both sides were basically not closed, many young people in Chongzheng clothes were seriously experimenting with something, and there were a lot of Jinyi guards and Dongchang masters outside, but few people paid attention!

The emperor's micro-service out of the palace was supposed to be kept secret, so naturally no one would notify them, Zhu Cijiong just walked and watched, seemingly careless, but in fact he was secretly observing.

Looking at his heart, admiration slowly grew, and I don't know how Song Yingxing trained these people, each of them was meticulous and focused on the experiment, the experimental conditions at this time were not very good, the entire eighth floor was full of strange smells, not to mention, the temperature was still relatively high, and most of the experiments they did were heating experiments, and they were basically using coal stoves, the temperature in the room was so high that it was conceivable, although there were fans, many people were still sweating profusely, but no one was distracted or stopped to rest.

It seems that Song Yingxing's success is not accidental, so many people focus on various experiments, and there is a person who is obsessed with research taking the lead, it is not surprising that he can produce results so quickly, he made up his mind again, this Song Yingxing must be rewarded.

As soon as he entered Song Yingxing's office, which is commonly known as the study in this era, Zhu Cijiong immediately asked cordially: "Chang Gung, if I remember correctly, just along the way, what was refined were asphalt, wax, lubricating oil, heavy oil, kerosene, and gasoline, right?" “

Song Yingxing gave Zhu Cijiong to the main seat, nodded and said: "Yes, the emperor, for the time being, these six things, Weichen must remember the emperor's teachings and strive to refine more things." “

Zhu Cijiong nodded and said, "Well, don't worry, you can do things, so let's settle the previous account first, I can't always let you work in vain." “

Song Yingxing was stunned when he heard this, and checked out? What to settle the bill?

The Ming Dynasty, and even the previous dynasties, did not have a precedent of rewarding money when something came out, plus he has been focusing on research, and he doesn't pay much attention to things that have nothing to do with research, so he has long forgotten about the reward that Zhu Cijiong mentioned last time.

Zhu Cijiong didn't explain to him again, but counted with his fingers: "Every thing that is refined is 100,000 taels, and six kinds of things are 600,000 taels, and the design of your large-scale experimental field is also very good, I will calculate 400,000 taels for you, and make up 1 million taels." “

One million taels! Song Yingxing finally remembered faintly at this time, the emperor seemed to have said that there would be a reward for the results, but one million taels is too exaggerated, it is simply an unimaginable wealth for him!

Such a huge reward really scared him, he swallowed a few mouthfuls of saliva, and said tremblingly: "Your Majesty, what do you mean, reward, reward, reward me with one million taels?" “

Zhu Cijiong smiled and nodded, "Yes." “

It's really a million taels, Song Yingxing's frightened eyes were about to bulge out, and he said in a panic: "Your Majesty, this, this, Weichen just did some research, one million taels, Weichen can't stand it!" “

When Zhu Cijiong heard this, he pretended to put his face on the face, and said seriously: "You have no jokes." “

Song Yingxing's neck shrank in fright, and he didn't dare to speak again.

Zhu Cijiong said directly to Cao Huachun: "Father-in-law Cao, wait for someone to go to the inner treasury to get two million taels of silver, send it here, one million taels to Chang Geng, and another one million taels to help him send to his researchers." “

When Cao Huachun heard this, he arched his hand with some embarrassment: "Your Majesty, please forgive Weichen for being stupid, these two million taels, is it gold, silver, Chongzheng Tongbao or dragon coins?" “

Zhu Cijiong slapped his forehead, turned his head and asked Song Yingxing, "Chang Geng, which one do you choose?" “

How did it become two million taels again! However, Song Yingxing will remember a little more, the emperor doesn't dare to resign from the reward, but if he resigns, he will bully the king!

Besides, the emperor is not rewarding him alone, he doesn't dare to ask for it, and he can't block the financial path of his subordinates, thinking of this, he hurriedly arched his hand and said: "Wechen thank the emperor for his grace, Wechen chooses dragon coins." “

Gold, silver, Chongzheng Tongbao he didn't dare to let people send it over, two million taels couldn't fit in that room, he had no place to put it, the dragon coins were much more convenient, at most only a box.

For a long time, the Daming Royal Nikko Bank has been very strict in controlling the issuance of dragon coins, and it has not caused any inflation.

Song Yingxing believes that his subordinates will also choose dragon coins, because each person is at least tens of thousands of taels, if they send gold and silver, who can carry it!
