Woo woo woo woo woo!

In the winter in Chang'an City, the wind is cold.

The pedestrians lowered their heads, either covering their cotton hats or tightening their coats, all trying to keep their heat in order to resist the damn cold.

However, although the weather is so cold, Rao Yongxiang from Guanshishan Academy of Chemical Academy was sweating profusely.

"Master, I found that the separation materials of kerosene are not that simple to distinguish. Although we know which isolate is kerosene is the most suitable for lamp oil.

But what is the use of the darkest thing at the bottom and the special fragrance in the middle is confusing."

Lian Zhijian has been very busy these days.

He first followed the craftsmen of the tincture oil workshop to Yanchang County to expand the tincture oil production there, and organized the construction of the tincture oil workshop to prepare to complete the tincture oil smelting directly in Yanchang County.

At the same time, he followed the first batch of kerosene that had been taken out on a large scale and returned to Chang'an City to help his master.

After all, the master and apprentice of Guanshishan Academy have the deepest understanding of tinea oil.

"In the words of His Highness the King of Chu, there is no garbage in this world, only things that are placed in the wrong place.

Although we don’t know what these things can be used for now, I believe they must have their own special uses.

First store them in different categories in the warehouse, and then find their use later, and then see what to do.”

Rao Yongxiang was also a little worried when he saw more and more refining materials.

Even if you want to throw these things away, you don’t know where to throw them away.

It was something that Li Kuan strictly prohibited to pour directly into the Weishui River.

If it were thrown into some wilderness, something seemed wrong.

Especially the dark mud left on the end after the distillation of tincture oil seemed to be invincible and I didn't know where to put it.

"Or why don't we just go and invite the King of Chu to our research institute to see if he has any good suggestions for these things.

I find that many times the words of His Highness the King of Chu are overwhelming our frownful thinking for several months.”

Lian Zhijian has seen Li Kuan with his own eyes and is also a fan who is very superstitious among the students of Guanshishan Academy.

"The way of scientific research requires continuous research on one's own way, so that you can get unexpected gains.

If you ask His Highness the King of Chu every time you have any difficulties, then how can we grow up?

Let’s first store the things in different categories according to what I said just now. When there is really no place to store them, we will ask His Highness the King of Chu.”

Rao Yongxiang obviously didn't want to give up so quickly.

Of course, in his heart, he also felt that his prince should not be omnipotent.

His Highness the King of Chu had never been exposed to this tincture oil refining material before.

How could he know what to do?

Isn’t I asking questions so recklessly? Isn’t I asking His Highness the King of Chu?

This is something that damages the glorious image of His Royal Highness of Chu, I cannot do it myself.

"Okay, but in this way, we need to continue to purchase a large number of oil storage barrels."

"Buy it, hasn't the Jintai ironworking workshop started to use steam engine equipment to produce oil storage barrels? Go to their workshop to order a batch of oil barrels and store these things well.

Remember, all storage items must be recorded in a classified manner, so don’t be able to figure out what they are storing at that time.”

When Rao Yongxiang thought of those refined materials, he often could not clearly see the difference from the appearance.

If you get confused, even if you find useful things in the future, you may not be able to use them.

"Don't worry, every bucket I have a separate record."

...

In the Eastern Palace, Prince Li Zhi and Yu Zhining were talking in the study as usual.

Although Li Zhi still had a low presence in the court, he gradually had his own team.

Li Shimin has gradually felt that his body is indeed not as good as before, so he is also consciously cultivating Li Zhi.

Of course, he would not let go of the power in the court.

In fact, no matter which emperor it is, after trying the taste of power, as long as he has breathed a sigh of relief, he will be reluctant to give up the rights in his hands.

It is said that rights are the best aphrodisiac for men, and there is absolutely no falsehood.

This is true in ancient and modern times, both in China and abroad.

So even if Li Shimin intends to train Li Zhi, he will not reduce his rights.

He still has the final say in the big and small things in the court.

Li Zhi is as transparent as ever.

"Shi Yu, how are our whale oil lamps sold recently?"

Although Li Zhi is not very concerned about commercial matters, he can read the main newspapers in Chang'an City.

The most important thing is that many of the East Palace are now kerosene lamps.

In the cold wind, the kerosene lamp with glass lampshade seems to be not affected at all.

Unlike the whale oil candles used to be, the candlelight shook violently when the wind blew, and there was no way to read and write.

"Your Highness, the old minister specially arranged for the housekeeper in charge of the business in the mansion to take charge of this whale oil lamp. However, in order to promote kerosene lamps, the Chu Palace used all means to give a large amount of benefits to various kerosene lamp workshops, so our whale oil lamp is a bit awkward now."

Yu Zhining's old face showed a little shyness.

Obviously, the sales of whale oil lamps are definitely not optimistic.

Although theoretically, whether it is kerosene or whale oil, the same lamp can be used to achieve similar results.

But when you actually use it, you can clearly feel the difference.

For example, a kerosene lamp, even in the cold winter, it is still oily, and it can be added to the lamp oil once a few days.

But whale oil lamps are different, they are solid in winter.

Of course, whether it is liquid or solid, it actually doesn’t matter much.

The biggest concern is that the kerosene lamp is too durable.

Most people don’t need to add lamp oil once even if they use it for a week.

But the whale oil lamp is different.

Not to mention when adding it, solid whale oil is a bit difficult to add.

Even if the addition is completed, it often takes one or two days to add it again.

If the brightness or other aspects of the whale oil lamp have obvious advantages, everyone may tolerate this inconvenience.

But compared to kerosene lamps, its advantages are very less obvious.

At most, black smoke will be less than kerosene lamps, but the less is limited.

In this way, whale oil lamps immediately have no future in the face of low-priced kerosene.

After all, the money for buying a lamp is actually almost the same.

However, the cost of using a lamp is much worse.

Yu Zhining probably hasn't completely understood these things yet.

Of course, even if he figured it out, he would not tell Li Zhi, and would only blame the King of Chu Mansion.
