Yelulie turned around and said to the excited servant Kui Yu: "The Warat people have tried it with thousands of iron horses, and all of them have become barbecued, do you have any brains?" If you take another 10,000 steps back, it is very useful to attack 500 infantry with 1,000 iron cavalry? "The cost of training and equipment for one cavalryman, generally speaking, is almost enough to equip and train ten infantrymen.

"Let's go right away, this is not someone we can move now." Yelulie said to Xiao Tienu, "Hurry up, I have a premonition that I don't feel good!" "Xiao Tienu and Kui Yu, who have served the Yelu family for generations, carried out Yelulie's order very quickly.

Just after they left about half a stick of incense, a cavalry squad came to the herbal tea shop, saw the tea shop that had gone empty, asked the owner of the herbal tea shop a few words, left two horsemen to guard here, and the rest of the people rode back to catch up with the group.

"Sir, there's something wrong with that guy!" Du Ziteng returned to the team and reported to Ding Yi, "The disciple thinks that it is better to inform the brothers of the Yamen of the Security Bureau along the way...... "It was not Du Ziteng's fuss, but Ding Yi's assassination last time, which was too shocking.

Ding Yi shook his head and said with a smile: "If you care, you will be chaotic." ”

Du Ziteng thought for a while, but his face was filled with guilt, and he immediately bowed and said, "The disciple is respectfully taught." Immediately, he instructed his subordinates to start from this newly opened herbal tea shop, and ignore Yelulie and the others who left. Just because I don't know which direction the other party is going from, at this time it is the suburbs of Beijing, and there are many cars and horses, if the other party comes to a golden cicada shell, let the convoy go first, and ride a horse or walk in the other direction, where can I keep up?

The reason why I found out that this group of people was wrong was because the location of this newly opened herbal tea shop was too good and too bad.

Ding Yi, out of professional habits, felt that this herbal tea shop was a little weird when he passed by, because it was naturally good as a spy stronghold. Not only is there a creek behind the herbal tea shop, which can escape from the waterway, but also not far from the fork in the road, once something happens, you can mix in the commercial houses and convoys from the south to the north at any time;

But this place is too close to Beijing, and the people who go out of Beijing will have friends to send each other, and in the front of the long pavilion, they have also responded to the reward, and came to this fork. They are all in a hurry, how many people will come here to rest? And if it is still early in the day, hurry up and go into the city; If it is late, you should also go to the inn outside the city in front of you to stay overnight. Who drinks herbal tea? As a business, it's completely out of tune.

But someone just spread the tea here. There are also gorgeously dressed people resting in this tea shop!

And those slaves in the shade of the trees. It's completely a look like you're going to get on the car at any time, which is even weirder, the owner is not in a hurry, and this person doesn't seize the opportunity to be lazy, and he looks ready to go? Don't talk about slaves, these years. Even soldiers don't necessarily have such a heart. Unless it's a Jiangyang thief with a case on his back, or an assassin spy, he will do this.

Ding Yi didn't pay attention to this stubble matter anymore, if he put his mind on preventing this every day. Then don't do anything, these things are no longer a problem for him to consider, at most it is to mention Du Ziteng. In fact, Ding is now responsible for the entire R&D planning, laboratory, resource exploration, investment and joint ventures, etc., if possible, Ding Yi is more willing to fight with a knife, which is something he is familiar with and good at.

But it was clear that he couldn't do it, it was too unsafe and too slow.

Ding Yi is no longer a horseback rider, and sitting in the carriage, he wrote down a line: potassium salt and hydrochloric acid react to obtain potassium chloride, and then react with a strong oxidant to obtain potassium chlorate...... He was very worried that as time went by, he would gradually forget these things, Ding Yi felt that he was beginning to integrate more and more into this era, and sometimes he doubted that the rectification of these things beyond the times was really to restart the Ming Emperor* country where he was located, so that the Chinese nation could return to the strength of the Han and Tang dynasties?

Or is it just to prove that the life of that distant era and decades is not just a dream, but a real experience, battle, life, love and pain? Life is a collection of countless memory fragments, and he is afraid of losing those fragments?

Ding Yi closed the note in his hand, whistled, the four-hoofed snow horse galloped happily from the back of the team, Ding Yi got on the horse, he didn't want to think too much, the previous life, the present life, no matter where he was, he was Ding Yi, maybe one day, he would forget the unforgettable past, but he would eventually step forward, in this era.

On the way back to Rongcheng, there were not too many twists and turns, although Wu Dugan led the men of Shuanghuri and hung far behind, but no matter whether Ding Yi and these people were camped or not, it was really difficult to have any chance for them to be caught. Ding Yi didn't know how to set up a big tent, and it was difficult to tell which tent Ding Yi lived in after setting up camp.

And every night the camp is the soldiers take turns to work for more than an hour to do the civil fortifications, there are cutting tree trunks to build a lookout, there are trenches, there are horses to resist, the soil dug out, but also to shoot out the chest-high breastwall, outside in all directions also placed hay and firewood, not to mention a dozen people, even if they lead a thousand iron horses over, Wu Dugan does not feel confident that he can step through such a camp.

She was not as innocent as Servant Kuiyu, and she was even more careful than Yelulie. Wu Dugan, who was hanging outside the range of the sentinel cavalry, even carefully observed the footprints left by the five hundred soldiers, and came to the conclusion that they must have at least a layer of iron armor on them. When those soldiers set up camp, she asked Shuanghuri to bring two good hunters from the grassland, and looked out in the forest from afar, these hunters knew how to hide themselves, unless Ding Yi himself came out to sentry, otherwise it would be difficult for others to find their traces sixty paces away when Shuanghuri was lurking with those two companions.

"If you go on like this, how can you find an opportunity to do it?" Shuang Sun muttered and frowned, because Ding was surrounded by guards when he came in and out, and it was definitely not easy to find a flaw. It's just that shooting now, in fact, is no different from sending them to death, they are here to kill, not to be killed, there is absolutely no reason to hit them so up.

Wu Dugan shook his head and said, "You can't be in a hurry, isn't Min An brave?" If he wasn't so eager that day, how could he be killed by Ding Yi? As long as we wait, we can finally find an opportunity, and they Han people said that there are a thousand days to be a thief, and there is no reason to prevent thieves for a thousand days. ”

This group of people, but it is not something that Ding Yi can know, after all, Ding is not a humanoid radar, and it is impossible to deduce the Wu Du who has not shown any traces. He was in a hurry to return to Rongcheng, because he vaguely remembered how Lei % mercury was made, maybe he was not in a position to produce cartridge shells now, but in any case, it was also a technical reserve. And he believes that these craftsmen, their families and apprentices will greatly improve the efficiency of Li Gongtou, and the craftsmen of Wang Gong Factory are the best and most stable output of mechanical talents in this era.

But time passed little by little, and until July, Ding Yi did not achieve any substantial technical progress, except for the monoculars, there was not a single product worth mentioning. On the contrary, ten mirrors and twenty sets of glass, under the operation of Liu Yiyi, sold at a crazy high price, of which the bulk of the profit is those mirrors, as for the glassware, although a set is sold for a price of several hundred taels to a thousand taels of silver, but in comparison, it is really nothing.

Because in this era there are natural crystals, glaze and so on, and skilled craftsmen will use a certain raw material to a point that is difficult to believe in the current conditions. For example, ivory mats are cut into thin slices, polished and shredded, and then woven into mats with these silks, and each ivory thread has to be processed through countless processes.

So these glassware didn't make much of a shock to the market, but the mirrors were terrible, because there was never such an object in the world.

And the stagnation on Ding Yi's side is also because of money, during this time, whether it is the income from maritime trade or the huge amount of money from the mirror, Ding Ruyu's side has been paid for expenses. Whether it is the silver for the 3,000 people under the original command, or the various expenses promised by the generals of the Beijing division for 2,000 people, the money and armor to help them find a mother-in-law - according to the regulations of the imperial court: in order to enable the military households to bring their own clothing and plate expenses, the Ming Dynasty decree stipulates that those who cultivate military fields within three hectares can be exempted from miscellaneous labor, the question is - in fact, how can the military households have the money to buy these?

On the Nanjing branch of Thunder Academy, you also have to pull out the silver; Because Ding Ruyu no longer went south to serve, the 700 war orphans who were previously transported from Guangdong were all stuffed into Rongcheng, and their food, clothing, epidemic prevention, etc., are also a big expense.

Ding Yi was extremely frustrated and sat back and watched all this, how could he develop it without money? Don't you need money to find potash mines? Could it be that he roared in Da Ming Yaxing: "Lao Tzu is rich and wants to buy potash ore!" "Someone will come up and talk to you? Without money, this kind of R&D plan can only be stopped;

And the industrialization of the production process of yellow gunpowder also costs money, because the spin-off step is really a problem for ordinary college students thousands of years later, if it is not a related major, but for a person like Ding Yi who can survive in the drug lord's territory under the cover of an explosives expert, it is okay, but it takes time to recall various details. But it also costs money! Split up, the things produced, often can not be used, just the green alum transported thousands of miles away, even if it is originally the price of cabbage, the freight all the way to Rongcheng is not cheap, not to mention that there are people who are injured in the process of testing the assembly line, and they have to pay the silver and pension of the settlement family......

If it weren't for the order of thousands of pairs of iron armor, I am afraid that the entire workshop would have to be shut down. So Ding Yi had to face such a situation: after the scientific research results were put into production, he made money and made a lot of money, and he had no money to use, so he had to rely on Liu Yiyi to take out his personal money to maintain the operation of Ding's mansion. (To be continued......)
