"My lord, are you satisfied with the vegetable oil?" For the things produced by the system, Ye Bing is naturally confident that they will be recognized by these ancients.

"This vegetable oil is indeed a good thing for the benefit of the country and the people, and the utilization value is extremely high, and the amount needed in the future is only high." Zhang Chadong commented pertinently.

"My lord, about the sale of the imperial court?" Vegetable oil being recognized is basically half the battle, Ye Bing asked after him.

"Although vegetable oil is a good thing, but in your hands it is undoubtedly a knife hanging on your head, and there is a threat to your life at all times, my suggestion is that you sell the secret recipe for refining vegetable oil to the imperial court, the price is negotiable, 100,000 taels of gold." Zhang Chadong gave reasonable suggestions based on the facts, and it has nothing to do with him whether the other party is willing to accept it, but he must not let his own son participate in this matter in the later stage.

"No problem." Only Gu Peng knew the method of refining vegetable oil, and he was very happy to agree to it.

"Little prince, you are really as rumored to be, you are talented and intelligent, different from ordinary children, and you are very transparent." Zhang Chadong couldn't hold back his unprecedented opening and praised for a while.

"Uncle Zhang, don't be in a hurry to boast, my words are not finished yet, we don't want gold, we want equivalent related treasures." Gu Peng didn't believe these flattering words.

"No problem." Gold and treasures are the same in Zhang Chadong's eyes.

"Uncle Zhang, even if you buy the secret recipe now, you can't make a batch of vegetable oil out of the first place, in this case, you can still buy it from us in the early stage." Selling the secret recipe is a must-win in the trend of the situation, and they can't keep it before they have a strong force, which Gu Peng knows very well in his heart, and now he can make a lot of money by selling it than being robbed directly in the later stage.

And even if Zhang Chadong got the secret recipe for making vegetable oil, due to the scarcity of oil crops, if you want to produce it in large quantities, you have to plant vegetables first, but now that the autumn harvest is approaching, naturally you can't plant seeds anymore, and you will have to harvest a wave of oil crops next year, which will delay a year, and this year the imperial court will have to sell vegetable oil from them, which means that they will indirectly earn two shares.

Zhang Chadong, who understood the key points, didn't say much, after all, the value of the secret recipe of vegetable oil cannot be estimated with money, and the imperial court is fortunate to get it, and it is not impossible to buy vegetable oil from them before it is developed, but there is a prerequisite, "How many vegetable oil you have in the imperial court can buy all of them, but if the enemy country appears in large quantities, Hugh blames the old man's subordinates for not showing mercy." ”

"Uncle Zhang, don't worry, your son Zhang Daxian and Zhang Luo are all about selling vegetable oil, and I and I will not be contaminated." In other words, they only provide vegetable oil, and who Zhang Daxian sells to is not within their control, but Zhang Chadong, as his father, can also intervene in it.

Although he knew that these two people wanted to push his son out as a shield, but danger and opportunity coexisted, and he would definitely write in the name of his son's discovery of vegetable oil when he went back this time, so that he would definitely win the favor of the current emperor and help him in the future.

After considering the disadvantages and advantages clearly, Zhang Chadong did not object to this matter, but in the future, he would have a headache and send people to stare at his stupid son, hoping that he would not die.

The quantity of animal oil is limited, and the emergence of vegetable oil can be completely replaced, but because the natural gold is not popularized in the early stage, in order to prevent the enemy from maliciously buying, this quantity must be controlled, and the price is only high.

Large quantities can only be sold to the imperial court, at the price of 1 tael of silver per jar, after all, selling the secret recipe has made enough money, and now it is the cost price.

The retail price outside is controlled at 10 taels of silver per jar, which is sky-high for ordinary people, and it is only a small meaning for the rich, after all, a jar of vegetable oil can be eaten for a long time.

And this price has to be divided into seven or three by the imperial court, and the imperial court has seven and three of them, they only ship, and the transportation and sales are all responsible for the imperial court.
