After making the soap, there is still some cloudy soap and alkaline waste on the bottom layer in the pot.

He skimmed out the middle layer of turbidity and put it into a basin. The ingredients in this are mainly the final reaction of the final monster oil and impurities, as well as a small amount of soap. Su Fan added the mixed brine to it and stirred vigorously.

After a while, the Warcraft oil in the basin changed again and gradually solidified. Su Fan looked at the shiny demonic beast oil block, and couldn't help but feel satisfied, sure enough, knowledge is power!

Add caustic soda to Warcraft oil, and after the reaction, soap will be obtained, and hydrochloric acid will be added, and another substance will be generated.

Wax, that is, the candle used for lighting in every household after a power outage in the previous life.

Qian Yunxian and the maid who held the soap and didn't let go were like flowers, watching Su Fan toss and turn for a long time, and now seeing that he finally stopped, he couldn't help asking

"What the hell is the young master tinkering with?"

Su Fan proudly pointed to a basin and said, "This is - wax!." “

"What is wax for?"

A term that I had never heard again, made the charming and moving Qian Yunxian and the maid stunned for a while.

Su Fan asked the maid Ruhua to take a piece of cotton thread, use the tea bowl as a mold, and make a candle on the spot to light it.

"How about it?

Qian Yunxian and the maid looked at the bright yellow flame in surprise.

"It's on, it's on, miss, this ,,, is much brighter than an oil lamp, it's amazing, it's almost like a glowing array."

Qian Yunxian stared at the flames and said, "It doesn't seem that the smoke is big." “

Su Fan laughed, of course it is not big, the impurities in the oil and wax are much less, so the smoke is much smaller than the ordinary wax.

"If this wax is taken out and sold, it should be able to sell for a good price. Qian Yunxian began to calculate.

Su Fan pointed to the pot of soap and said, "Compared to oil wax, this pot of soap is more valuable!"

Qian Yunxian and the maid Ruhua were convinced of this, and glanced at Su Fan charmingly, raised their eyes and smiled

"Young master, I really want to know how it grows in your head, these ordinary people can't get it, and it can be used as an heirloom formula, but you can catch it, the slave family is really curious."

"Because I stand on the shoulders of giants, knowledge is power"

Su Fan laughed.

The maid Ruhua pointed to the half pot of waste liquid in the pot and said, "Can this be poured out?" “

"Can't pour!" Su Fan hurriedly said: "Compared to soap and wax, this is the real treasure!"

The excited overreaction frightened Qian Yunxian and the maid like a flower, and looked at a pot of waste liquid curiously, is this really a treasure?

As a scientific research assistant, Su Fan knows better than anyone that these waste liquids contain a substance that is 100 times more precious than soap and wax - glycerin!

Glycerin is a clear, viscous liquid that has no color and a sweet taste. It is an extremely important chemical raw material, and its wide range of uses covers almost most of the chemical fields.

It has applications in food processing, pharmaceutical, industrial machinery lubrication, plasticization and other fields, such a precious thing. Wouldn't it be a shame to throw it away?

As long as Su Fan extracts glycerin from the saponified waste liquid, with this thing alone, he can earn Qian Yunxian more than ten thermal insulation workshops! After simple dilution and clarification, Su Fan can extract glycerin sweet water from the waste liquid.

In fact, from the synthesis of artificial glycerin, the previous glycerin was refined by saponification of animal and vegetable oils. This half-pot of waste liquid contains about 10% pure glycerin.

The glycerin sweet water with the alkaline precipitate removed is pale yellow, and the smell is unpleasant, Qian Yunxian and the maid Ruhua really don't understand, what is the use of Su Fan asking for these stinky water...... I saw Su Fan's stinky water slowly poured into the filter jar that had been made a long time ago.

This monster has its harms, but things often have both sides to it, from the beginning of the spider needle pipe to the current filter altar, building the filter altar is labor-intensive and time-consuming, Su Fan directly replaced it with the intestines of the monster, I have to say that the strong body value of the monster is like a plastic tube in the previous life.

It doesn't take long to .......

There is a stream of water slowly gushing out of the thin tube at the bottom of the altar, and what is quite surprising is that it is not yellow water, but a clear and transparent liquid!

Su Fan looked at the clear stream that gradually flowed out, as if he was watching silver coins gushing out of thin tubes! As long as he simply distilled and extracted pure glycerin, then his financial plan would be ...... down.

Glycerin is widely used, but at present, the most practical and profitable way for Su Fan to think of is to use glycerin as a food additive!

Fruit wine additives, to be precise!

That's right, Su Fan's Mansion in this life started with winemaking, and from the broken memory, you can vaguely perceive the Su family's winemaking process, which has tasted, to be honest, really not good.

Although there is a recipe for "Monkey Wine" in the brain, it is really time-consuming and laborious to make it, and it is really thankless, but making fruit wine is different.

Because the brewing level of fruit wine in this era is extremely poor, the fruit wine produced is muddy, bitter and astringent, and no one drinks rice wine if it is not poor!

Even bitterness has become synonymous with fruit wine......

The people of the mainland of Kyushu only think that the fruit is not suitable for winemaking, and only use it to make wine when the fruit is abundant and backlogged...... And the price of fruit wine is also extremely low. Basically unprofitable.

Who knows, in fact, all fruits contain a substance called tannins, tannin is the source of bitterness and astringency in the fruit, no matter what kind of fruit fermentation tannins can not be decomposed, remaining in the wine, the natural taste of the fruit wine is bitter and astringent, extremely unpleasant, and the key to removing tannins!

Glycerin not only effectively removes the bitter taste in the wine, but also greatly improves the quality and taste of the fruit wine. It is an excellent fruit sprinkle additive!

As long as the bitterness of the fruit wine is removed, the wine is filtered and clarified. The sweet and clear fruit wine will surely become the most popular wine among the people of Kyushu!

Soap, candles, glycerin wine!

These are the three essential killers for the traverser that Su Fan took out at once!

Leizhou Great Qin State, Tianlei Pass.

Tianleiguan is full of people, the lights are colorful, the gray stone paved road is spotless, the shops on both sides of the street, whether it is the boss, the shopkeeper or the guy wearing their own best clothes, waiting for it, on the street, five steps and one sentry, ten steps and one post, wearing the standard armor of the Great Qin State, holding a fine iron spear, majestic, knife-like eyes patrol the dense behind them, showing excitement of the people.

At the gate of the Tianlei Pass leading to the interior, the wide official gate opened, and all around, the elite and energetic people of the Tianlei Pass in military uniforms stood like torches, and the rangers rode military horses, holding big swords and rushing to both sides, driving away the desolate people and desolate people entrenched in the surroundings!

The third prince of the Great Qin State, Ying Ruizhi, was dressed in a pale yellow tin robe, black and evil boots, and wanted to hang a long sword, handsome and chic, extravagant, and the strategist Liu Daoming behind him looked restrained, and next to him was the third prince of the Great Qin State, Ying Sicong, brocade robe, gentle and elegant, with a folding fan in his hand, a good handsome son, Wei Wende, a son of the family behind him, and Chang Sishan stood with his hands.

After the two of them, they were the governors of Tianlei Pass, and after the governors, they were officials in Tianlei Pass, as well as the gentlemen of Tianlei Pass who were highly respected and prestigious.

On the other side, countless disciples of the sect dressed in various strange costumes, with arrogant expressions, leading like the stars holding the moon are the children of the ethereal sect of the super grade sect, and then the high-grade sect, the middle-grade sect, the low-grade sect, the hierarchy concept of the Jianghu sect is deeper than the secular one!

The loud sound was accompanied by the flames rising into the sky, bursting into a brilliant brilliance in the sky, and in the distance, pieces of honor guards exuding dazzling golden brilliance under the sunlight came, the golden carriage dragged by nine snow-white beasts around them was dazzling, and thousands of palace guards wore golden armor, and the formation runes on the armor slowly shone brightly!

"Sons and daughters greet their father!"

"Sons and daughters greet their father!"

"Greetings to His Majesty!"

"Greetings to His Majesty!"

"Greetings to His Majesty!"

With the golden carriage slowly driving into the Tianlei Pass, the entire Tianlei Pass was boiling, cheers, shouts were endless, although the beasts invaded every year, it had to be said that this generation of the Great Qin State Lord was fighting for it, killing decisively, diligently, and having a very high prestige in the Great Qin State, and he was considered a Ming Jun.

And what makes the people of Tianleiguan even more excited, with the arrival of the lord of the Great Qin State, the long-awaited winter hunt is about to begin, in order to welcome the advent of the annual blood moon night and reduce the harm of the invasion of wild beasts, the purpose of winter hunting is to hunt monsters to the greatest extent!
