In the early morning of the first day, it was only slightly bright, and the housekeeper of the Xiao family had already brought a convoy to the iron workshop outside Jiangling City, dozens of carriages were loaded with some sulfur ore, iron ore, coal mine, saltpeter and other ore materials, because these resources were bought from various countries by the Xiao family spent a lot of silver, so of course the housekeeper had to escort them personally!

Now Zhou Chao is already the chief engineer of the iron workshop, Xiao Yao has completely handed over the iron workshop to him to be responsible, the first is because his ironmaking and casting skills are indeed very superb, and the other craftsmen in the iron workshop, including Master Li and others, all admire Zhou Chao very much, and all obey Zhou Chao's management; The second is because he and Gao Yuan are Xiao Yao's henchmen, so Xiao Yao is nepotism in this decision!

Moreover, Zhou Chao is also very good at production management, plus the iron workshop already has the rules and regulations of modern enterprise management formulated by Xiao Yao before, the combination of the two has greatly improved the production efficiency of the iron workshop, and also greatly improved the quality of various iron tools produced by the iron workshop!

Zhou Chao carefully checked the various materials sent by the housekeeper, and after receiving them, he personally sent the housekeeper out of the door of the iron workshop, and the two were polite at the door again, and Zhou Chao turned around and returned to the iron workshop. At this time, Liu Gonggong, who was hiding not far away and was secretly monitoring the iron workshop, opened his eyes wide, stared at Zhou Chao's back, and the corners of his mouth suddenly showed a hint of a wicked smile, and immediately rushed back to Ruyi Building!

Gonggong Liu hurried back to Ruyi Building, immediately came to Yu Wenzhi's room, and whispered to Yu Wenzhi, who had just woken up, only to see that Yu Wenzhi was more and more surprised the more he listened, and his head, which was still a little dazed just now, had been awakened by this news!

"Are you sure this person is the Qi person who was wanted by his father back then, Zhou Chao?" Yu Wenzhi asked nervously.

"My subordinates are very sure! Although this Zhou Chao has now shaved his hair and made up as a monk, I have also seen him a few times when he was in Zhou State, and he offended the Duke of Jin and is our enemy, so I still remember his appearance clearly, this monk hiding in the Xiao family's iron workshop is the one who wants to commit Zhou Chao! Gonggong Liu nodded affirmatively.

"Haha, that's really helping me! This time, I not only want the Xiao family to honestly hand over the glass formula to me, but I also want to offer their iron workshops with both hands! Yu Wenzhi immediately burst out laughing arrogantly!

。。。。。。

At noon in winter, the warm sunlight sprinkled on the earth, so that the temperature became warmer, Xiao Yao, who was still wrapped like a big dumpling, came to the ironworks under the protection of Gao Yuan and a large number of people, although these Xiao Feng asked him to show up as little as possible, but now the housekeeper sent a large number of materials to the ironworks, of course he wanted to come and have a look.

"Childe, it seems that this Yu Wenzhi is not only near Xiao Mansion, but even here in the iron workshop, he has also arranged a lot of eyeliner to monitor our every move!" Gao Yuan's martial arts are strong, and of course those sneaky eyeliners can't escape Gao Yuan's eyes!

"As the saying goes, the husband is not guilty and guilty! Who told us that the strength of Liang State is not as strong as that of Zhou State! In the territory of Liang Kingdom, they dare to monitor the Xiao family so unscrupulously, hehe, it is really reasonable to have a big fist, and I believe that our emperor does not dare to have any opinions on Yu Wenzhi's approach! Looks like we're going to have to do some preparation ourselves! Xiao Yao sneered.

Although Xiao Yao didn't know what tricks Yu Wenzhi would use against him, he had already taken out a lot of useful information from Yu Wenmin's mouth, knowing that the dead eunuch Liu Gonggong who came to Jiangling this time was also the dead eunuch Liu Gonggong, but this person has been sneaky and did not dare to appear openly, he must be carrying out some conspiracy, it can be seen that Yu Wenzhi's recipe for glass treasures this time is determined to win! So in order to prevent this Yuwenzhi from unscrupulously seizing the recipe of the glazed treasures, Xiao Yao also decided to make some preparations in advance, just in case of emergency!

Xiao Yao returned to the iron workshop, called Zhou Chao into the experimental room, and then handed him a few design drawings and instructed: "While the housekeeper has just sent a large number of materials, you will work hard, assist me, and make these things!" ”

Zhou Chao took a general look at these drawings, and sure enough, there were some things that he didn't understand very well, so he smiled and said: "Childe really has a lot of these whimsical ideas, grenades, smoke bombs, incendiary bombs, just look at these names and know that they should be some weapons, is Childe going to use them against Yu Wenzhi?" ”

has been by Xiao Yao's side for more than a year, and has seen Xiao Yao's power, and now Zhou Chao has absolute admiration for Xiao Yao, no matter what Xiao Yao commands, no matter whether he can understand it or not, Zhou Chao will do his best to complete it, do more and ask less.

"Yes, these are some weapons I just came up with for self-defense, but we can't deal with Yu Wenzhi here, if Yu Wenzhi has an accident in Jiangling, it will be equivalent to Liang Guo declaring war on Zhou State! When the time comes, as soon as the army of the Zhou State comes, don't let the Xiao family, the entire Liang State will be wiped out! So do these things just to be prepared, alas! In short, we have to do these things as soon as possible, and if you don't understand, feel free to ask me! Xiao Yao sighed.

When he knew that Yu Wenzhi secretly brought Liu Gonggong to Jiangling, Xiao Yao had a feeling of uneasiness in his heart, he always felt that this matter would end if it was not so simple, even if the Xiao family handed over the formula of the glass treasures at that time, Yu Wenzhi would not easily let go of the Xiao family, so he made the worst plan!

"Hopefully, these things won't be used by then! That's a good idea! Xiao Yao thought of the worst thought in his heart, then shook his head vigorously and sighed!

Work makes people forget their worries, and Xiao Yao and the others don't know that Zhou Chao has been targeted by Yu Wenzhi and Liu Gonggong, so in the current iron workshop, a group of people are still around the stove, seriously calcining the molten pig iron! Because the melting point of pig iron is lower than that of pure iron, only about 1,200 degrees, it can be easily calcined in the furnace that Xiao Yao has improved.

"Childe, this furnace of molten iron is calcined with pig iron ingots, but the pig iron is too brittle, and things made with it are easy to break, what is the use of these hollow iron shells cast by this furnace of molten iron?" Master Li asked puzzled as he poured molten iron into the clay mold that had already been made. Because this project was personally presided over by Xiao Yao and belonged to the highly confidential iron workshop, Master Li could only personally assist Zhou Chao in the operation, and his disciples and grandchildren could not even get close to this furnace!

"These iron shells are only used to hold things, and they just need to be brittle and easy to break! And these pig irons have a low melting point and are fired quickly! You see, in just a few strokes, we've already cast five. Xiao Yao looked at these five iron shells that were only the size of a fist, and nodded with satisfaction.

Master Li was in charge of casting the grenade shells, while Zhou Chao was carefully purifying saltpeter and sulfur according to the method given by Xiao Yao.

"Zhou Chao, are these two raw materials purified?" Xiao Yao looked at Zhou Chao, who was sweating profusely, and asked.

"It's almost done, the hundreds of catties of ore sent by the housekeeper this time, I have purified it according to your instructions, but what do you want to do with so much gunpowder, Childe didn't you have it before, and now it's not a high-profile time, you don't need to make a lot of muskets, but now you have made so much gunpowder, so when will it be used up?" Zhou Chao asked puzzled.

"Be prepared, and we can make grenades out of this gunpowder now! If you think about it, a musket can shoot a powerful bullet with just a little gunpowder poured into it, and if we put a pound of gunpowder into that iron shell, and then bang on the ground! The iron shell was blown to pieces in an instant, and these fragments were shot around like countless bullets, how powerful would you be? Xiao Yao showed a harmless smile.

"That power will be shocking, and it will kill countless people!" According to Xiao Yao's description, Zhou Chao tried hard to imagine the scene of the explosion.

"That's why this weapon is called a grenade, a bomb that can be thrown with one hand! By the way, and the most critical part, you have to use oiled paper to roll up these time-delay black powder I just prepared, make a fuse, and insert it into the grenade, and then you only need to light the fuse, and you can throw the grenade out! Xiao Yao pointed to a pile of black powder with zero wood powder and grease.

After assigning the process of making grenades, Xiao Yao personally went into battle, took out a pound of brown sugar and poured it into the pan, because at this time, the white sugar had not yet appeared in the Central Plains, so the brown sugar in Xiao Yao's hand was bought from Chen Guo by the housekeeper for a lot of silver.

"I didn't expect that these few catties of brown sugar would cost hundreds of taels, and it seems that when I have time, I will also improve the sugar making process, and it will definitely be a very profitable business at that time!" Xiao Yao said to himself while warming up the catty of brown sugar.

When the brown sugar melted and became charred, Xiao Yao poured two catties of saltpeter powder into the caramel, added some soda, and then slowly stirred it in the fire, and finally poured the coffee-colored paste into an iron bottle, also plugged in the fuse, and then sealed the bottle mouth with white wax, this is an earthen smoke bomb, because the mixture of sugar and potassium nitrate can produce a lot of smoke when burned!

Master Li cast the iron shell of the grenade, Zhou Chao also prepared the black powder, Xiao Yao began to load the prepared black powder into these iron shells in the experimental room, and inserted a fuse that had been cut and could burn quickly for ten seconds in the hole, and also sealed the hole with white wax, so that a primary version of the grenade was made!

I really don't want to use these things, but when I do, I don't hesitate! Looking at these fist-sized earthen grenades, Xiao Yao himself has been entangled in his heart, because Yu Wenzhi is determined to obtain the formula of the glass treasures, and he is really afraid that he will have some conspiracy and tricks at that time, and he will be caught off guard when the time comes! Because even if this is Liang Guo, but what Yu Wenzhi wants to do, I believe that Emperor Liang really doesn't dare to care!

After the secret weapons were made, Xiao Yao took a large group of people to block a barren mountain outside Jiangling City, and then he and Zhou Chao Gao Yuansan went to the mountain alone, because Xiao Yao was going to show the two of them how to use smoke bombs, incendiary bombs, grenades and explosives bags!

The three of them hid behind a mound of dirt, Xiao Yao first asked Gao Yuan to test the smoke bomb: I saw Gao Yuan ignite the fuse, and then vigorously threw the iron can, only to see that ten seconds later, the iron can suddenly spewed out a large amount of white smoke, and all of a sudden the iron can was covered with thick white smoke, which was very effective as a concealment cover.

Then there is the test of incendiary bombs, only a ceramic wine bottle, filled with purified alcohol, and then plug a rag at the mouth of the bottle, and then ignite the rag, and smash it hard at the target, so the ground is instantly surrounded by fire, and it cannot be extinguished with water, because the alcohol is dense in water and can float on the surface of the water to continue to burn.

Then it was the turn to test the grenade, Xiao Yao covered his ears, asked Gao Yuan to point the fuse on the grenade, and threw it vigorously into the pile of dead grass ten meters away! It was also ten seconds later, and there was a loud "boom"! The entire pile of dry grass was blown apart, which scared Zhou Chao, who was not mentally prepared, into a big jump!

The last is to test the explosives package, in fact, this explosives package is black powder wrapped in layers of a large amount of oiled paper, which is fully wrapped in five pounds of gunpowder, and then tied with a rope in all directions! Xiao Yao asked Gao Yuan to dig a hole dozens of meters away, and after burying the explosive bag, he quickly ran back with the fuse, and there was a loud "boom" again, and this time even a big hole was blown out on the ground!

Seeing that Zhou Chao Gaoyuan was stunned, Xiao Yao kicked them twice and scolded with a smile: "Just these few things scared you out, if we make a cannon in the future, it won't scare you all to death!" How can you mess with me with such guts! ”

"Childe, it's so powerful, I can't imagine that an iron pellet can be turned into such a powerful shocking grenade after being filled with black powder! There is also the smoking-smoking tin can but there is no fire, and the black powder can be wrapped into an explosives bag to play! Childe is really a fairy descending to earth, peerless and smart, so he can make a sharp weapon like a god! Zhou Chao was indeed frightened by these things just now.

Xiao Yao enjoyed the pleasure of being slapped on the back, and smiled happily: "Actually, it's just a few things that are made easily, plus muskets and revolvers, these things are currently our secret weapons!" When we get through this difficult time, I'll teach you to do something more powerful, and then we won't have to be bullied again! ”

"Childe's magic is clever, and he is blessed by the gods, now with these powerful and terrifying weapons, even if there are ten Yuwenzhi, we don't have to be afraid of him!" Gao Yuan also patted Xiao Yao's sycophants.

"It's easy to deal with Yu Wenzhi, but it's difficult to deal with Zhou Guo behind him! There is no diplomacy for a weak country! Alas, you have to hide all these things so that no one can know about them, and the hundreds of pounds of gunpowder we have prepared, these are the killer weapons in our hands! Hopefully we won't use these things! "During this time, Xiao Yao's heart always felt unsteady and a little flustered, in fact, this is not the performance of not being able to control his future, after all, Yu Wenzhi is stronger than the entire Xiao family and the entire Liang Kingdom, Xiao Yao is not capable of fighting him now!
