Only Zhen Qian knows that this seemingly miraculous thing is just an immature half-finished product, and there are still many things that have not been solved if it can really be used?

The fuse is too long, the purification process of raw materials, the particle problem of black powder, even an ordinary iron shell is not easy to make, and finally it is a cost problem of homemade bombs.

And Zhen Qian developed black powder at this time, but he didn't want to kill people, the real purpose was to prepare to dig a wine cave in the valley, and specially invited Song Yi to come over to check it on the spot, although Song Yi is a stonemason, but he is no stranger to digging caves, and after reading it, he told Zhen Qian that if he wants to dig a cave here, it will take twenty or thirty craftsmen more than a year to dig a small wine cave.

How can Zhen Qian have so much time to waste, I can't wait to conjure up a wine cave tomorrow, but as soon as I heard Song Yi say that to dig a cave, you need to burn the rocks with fire, and then pour water on them, and use the principle of thermal expansion and cold contraction between one cold and one hot to peel off the rocks one by one from the mountain, and it would be good to be able to dig a cubic rock in a day, of course, if Zhen Qian is willing to invite one or two hundred craftsmen, the time can be greatly shortened.

The primitive hot and cold method of digging the cave was protracted, and a large wine cave could not be completed without taking several years, so Zhen Qian could only pin his hopes on black powder.

Zhen Qian also knew how dangerous it was to use black powder to open a mountain, especially the amount of black powder and the design of the explosion point, not to mention that Song Yi didn't understand, even Zhen Qian didn't understand. However, after experimenting with black powder, Zhen Qian's worry disappeared out of thin air, because he found that he could control the ratio of black powder and reduce the explosive power of black powder to a minimum.

He and Zhen San experimented a few times, and called Song Yi to dig a hiding hole in the mountain, and the effect was very good, as long as there was enough gunpowder, he could even dig a simple cave within a month.

After showing the miracle, Zhen Qian secretly remembered the performance of everyone, as for the bloody scene, he didn't want to stay longer, he didn't even kill a chicken in his previous life, this is not to say that he has a good heart, but the bloody scene only stays in film and television dramas, which is not only very different from the real scene, especially the rich blood in the air, which makes people can't help but have the urge to vomit.

This feeling was also shared by himself and the two little girls, and the others were shocked by this scene, and it was not until they returned to the entrance of the valley that their stiff faces eased a little.

In these years, Taoism was advocated, and Taoism preached the art of immortality, in addition to tinkering with some so-called elixirs, that is, looking for immortals who did not exist at all.

Suddenly, after seeing the so-called miracle, Zhen Qian was already hooked with the immortals, which made them have an impulse to worship Zhen Qian in their hearts, but they didn't know if they would want to ask Zhen Qian about the art of immortality.

Next, these people saw that Zhen Qian's mentality had changed, and there was a lot more respect and awe from the heart, Zhen Qian also used a whole sheep banquet to temporarily dispel their curiosity, and even Zhen Er, who likes to show his muscles all day long, called his father-in-law at the same time, the unruliness in his eyes disappeared, but turned into a deep fear.

It is important to make money by making wine and opening a restaurant, but having money does not necessarily mean that you can save your own life, so making a Tang version of the soil bomb is only the first step, which Zhen Qian thinks very clearly.

After Wang Peng gave the gag order, the people who knew the existence of the miracle no longer kept their mouths shut about it, and they all knew in their hearts what it meant for this matter to be spread, of course, not only were there bad things, but there were also a lot of envy and secret joy, so this whole sheep feast was eaten happily, and many people were drunk.

Although he brewed his own soju, he was not interested in soju, and he usually liked to drink all kinds of fruit wine, and the amount of wine was not large, so he drank a few more glasses of wine today, and when it was over, his head was a little dizzy, and Xiaomei, who was clever, prepared a bucket of hot water early, so that Zhen Qian could soak comfortably to disperse the wine.

Wang Qun didn't come with him this time, there was something to pass on the news to Zhen Qian, he was busy studying gunpowder with Zhen San a few days ago, and he didn't have time to ask, at this time Xiaozhu was nagging beside him.

"Uncle Wang sent news that those Hu merchants had already negotiated the matter of soju with Song Yi of Zuixianlou, leaving ten taels of gold as a deposit, and he would really buy five hundred jars of the strongest soju every three months in the future, and said that he was willing to help Song Yi open a branch of Zuixianlou in Fanyang and other places, and asked Song Yi if he wanted to cooperate?"

After speaking, Xiaozhu secretly glanced at Zhen Qian, who was lying motionless in the bucket, and found that his brows were slightly furrowed and he didn't make a sound, so he continued: "The Hu Cake Shop next to Zuixian Lou is willing to cooperate with Song Yi to rent or sell the front yard of the Hu Cake Shop to Zuixian Lou, and I want to be a partner in Zuixian Lou, Song Yi asked how to deal with this matter?" ”

"Yes! Tell Song Yi that all the Hu Cake Shops next to Zuixian Building can be rented, and the Song family can all move to the Hu Cake Shop to live, and the second entrance of Zuixian Building can be vacated and converted into a two-story private room, and the backyard will be used as a kitchen and storage room, don't ask me about other things, let him handle it single-handedly. By the way......, the front yard of the cake shop has been converted into a grocery store, and it is best to complete it before the end of the month, and I will use it then! ”

Xiaozhu recorded Zhen Gan's words on paper, and saw that Zhen Qian didn't speak again, and said a few more small things, but he didn't bother to speak in the end, obviously unwilling to worry about trivial things, so he shut his mouth stupidly.

"Lang Jun, since you don't want to listen to these little things, then the criminal housekeeper has released the rumors of the separation in the Zhen family, aren't you going to teach a lesson?"

Zhen Qian opened his squinted eyes a slit, and said with a sneering smile on the corner of his mouth: "If he doesn't spread it, he won't be a criminal steward, do you think he dares to do this, there is no criminal intent behind him, don't speculate!" ”

After the last confrontation, Xiaozhu actually found that Zhen Qian's thunder was heavy and rainy, and the criminal housekeeper was doing a steady job in his position, and the things that Zhen Qian said were at most a little restrained, but he did not beat the criminal housekeeper to death with a stick, which made Xiaozhu, who was full of hatred for the criminal housekeeper, very dissatisfied, and wanted to sweep the criminal housekeeper out of the house.

The criminal housekeeper is a dog released by the criminal family, and it depends on the owner to beat the dog, besides, this dog is still loyal to the owner now, it is so easy to kill, Zhen Qian naturally will not chase and beat the criminal housekeeper, thinking that as long as he completes the matter of dividing his family, naturally the criminal housekeeper will not be put on the table at all.
