Jiang Yuntian said: "I choose Han Dong's side? Song Che shook his head: "He shouldn't give you the power of the army." ”

"Then I choose He Qiu's side?"

"He's a very shaft person, you shouldn't get any benefit."

"That means, I can only choose Gao Chen? He is a military attaché, I am a military general, and I should be the most suitable. ”

"Gao Chen is indeed more suitable for you to stand in line, but he still has old feelings for the previous dynasty, with Brother Liao's temperament, it is estimated that he will not be treated very well, if you choose him, you may suffer."

"Snort...... It's really troublesome, I'll pick a fart, I'll choose! That's what I hate the most! forced me to be anxious, resigned to follow you in business, and lived this rich and prosperous life. ”

"The emperor will probably not let you go."

"Then I will elope with the princess and go back to Nantian Valley, escape from the world, and be happy!" Jiang Daxia is really a cute and innocent person.

Song Che laughed. Jiang Yuntian said angrily:

"What are you laughing at? It's so tiring to talk to you people, and it's hard to understand when you talk and don't speak directly, and laugh out loud for no reason in the middle of speaking! ”

"Hey, don't be angry, I'm just teaching you, the higher a person's position, the wider his vision, the more temptations, and the more painful the same fall will be," Song Che smiled: "I have seven words here, as long as you learn it, no one in the court will depend on you to live, you listen well, these seven words are - 'don't know' and 'someone knows'." ”

"Don't know? Does anyone know? ”

"The three words 'don't know' are used to deal with ministers, when they disagree with politics and ask for your opinion, you respond to them with 'don't know'; when you don't want to answer the emperor's question, tell him that you don't know, and if he insists on asking, you tell him 'someone knows.'"

"Then if the Emperor asks me, who told you that 'someone knows'? How do I answer? ”

"Just tell him you don't know."

"Does he have to know?"

"You just tell him 'someone knows,'" Song Che smiled and patted Jiang Yuntian on the shoulder,

"Generally, people with normal brains, after asking twice in a row, should know who 'someone knows' this 'person' who knows." Jiang Yuntian exclaimed: "It's you!" Song Che smiled: "You see, even you know it's me, how can they not know?" ”

"Ah...... I must have a son and marry your daughter, so that my grandson will be as wise as you in the future!" ”

"Hahaha, then you have to work harder with the princess." Song Che is not teaching Jiang Yuntian tongue twisters, he knows very well the character of his brother, Jiang Yun was born to be a chivalrous man who is happy to enmity and revenge, where will he understand the sophistication of the people in the court?

The three words "don't know" are often the most middle-of-the-road and most accessible choices.

The words "someone knows" are for him to make the most moderate and out-of-the-box choice for him.

Hopefully, no one will force him to make a choice. …… Jiang Yuntian rested in the Song Mansion for the night, and returned to Jinling with the princess the next day.

In mid-July, the fair also ended successfully, and in just one month, Yunshuifang received orders for 100,000 pieces of silk, and other stores such as jewelry stores could also be described as a bumper harvest.

The turnover of the world's money houses is as high as 800,000 taels of silver, and many merchants are willing to deposit their gold and silver coins into the bank.

An exhibition from south to north has restored the sluggish market to its original appearance. On the second day after the end of the exhibition, Tang Hulu, a wealthy Persian businessman who cooperated at the beginning of the year, finally returned to Hangzhou with his goods, and the whole 30 large ships and nearly 50,000 barrels of oil occupied half of the Qiantang River port.

According to the agreement, Song Che ordered the corresponding amount of silk to be loaded on the ship, and Tang Hulu facilitated the first transaction.

"Boss Song, the amount of oil you want is too large, and I also found a lot of royal connections to bring these thirty ships of oil, and our King said that only after wearing your silk can the next round of cooperation be carried out." Tang Hulu meant that the next batch of oil would not arrive until the 50,000 horses of silk were shipped back to Persia.

It takes at least three or four months for the silk to come back, and the same time for the next shipment of oil, which takes a year before and after the sale.

Song Che didn't know anything about oil refining, but with 50,000 barrels of oil, he estimated how he could refine 10,000 barrels

"Fierce fire oil", right? Fierce fire oil, in the past, when he was fighting against the Japanese in Chuzhou, Song Che was in the ordnance prison and saw it

"Fierce fire oil" is a thing that is refined from oil, and the refined fierce fire oil is poured into an iron can, and thrown to the enemy position through a catapult when the battle is in battle, thus causing a fire to burn the enemy; The reason why fierce fire oil is called

"Fierce", precisely because the burning flame is very large, it can be attached to the body skin, once ignited, until it is scorched, it can be described as a very cruel firearm.

Now Dijon Pan turned to attack and defend, entrenched in the city, to drive them back to the north, the first thing is to fight siege warfare, after the battle of Xuzhou, Dijon has seen the power of artillery, will strengthen the city wall and city gate, in the siege war, artillery seems to have become dominant, must use more powerful firearms - fierce fire oil, is one of the big killing weapons prepared by Song Che for the Northern Expedition in the coming day.

When Dijon had not yet broken through the barrier last year, Song Che asked He Qiu to build a set of oil refining equipment, which is now placed on Shedao, and the 50,000 barrels of oil purchased from Persia will be refined and purified on Shedao in the future, and the refined oil will be used as a strategic reserve for recovering mountains and rivers in the coming days.

For this reason, Song Che made a special trip to Shedao to visit the alchemy skills and oil refining technology by the way.

The gold mine in Shedao is terrible, it can chisel 500 tons of gold ore in a day, and each ton of gold ore can be refined into about half a penny of gold sand, which is converted into about 50 taels of gold a day, and 1,500 taels of gold a month!

It's no wonder that the former Great Pirate King built his lair here, and this island is really one

"Gold Mountain". Regarding the process of oil refining, Song Che thought it was very complicated, but after seeing it, he realized that he was too complicated, and besides, with the backward technology of ancient times, it is not complicated to think about it, and the whole is just one word - boil!

In ancient times, most of the purification processes were heated and cooked, such as salt, spirits, ironware, and even gold; For example, it's like boiling eggs

"Heat", the egg white will solidify at 80 degrees Celsius, the egg yolk will solidify at 100 degrees Celsius, the eggshell may be broken at 200 degrees Celsius, and it will be burned to charcoal at 1,000 degrees Celsius; The same is true for the petroleum refining process, the craftsmen will increase the fierce fire, burn the temperature to 300 to 400, the oil and impurities will be separated by heat, and after precipitation, it will be stratified, and the oil floating on the surface will be scraped away, and the fierce fire oil can be obtained!
