Speaking of which, the advantages of this glass greenhouse are much more than ordinary greenhouses! Not only is it beautiful and sturdy, but it also doesn't have to cover the upper layer with a straw curtain on a winter night to keep warm.

It's just that I forgot about glass for a while~ that is, the value of glass in this era.

"Isn't this a bit excessive? But forget it, it's not worth much anyway......" I muttered to myself.

Ignoring the gazes of the others, I continued to instruct the gardeners and craftsmen of the Imperial Garden to plant the various plants I had taken out. Including corn pumpkin~ It's just that I consider that this is an experimental planting, so I don't need to plant so much at once. So only about 100 grains of corn were planted. Since I hadn't actually planted it, I just dug a pit and planted it a short distance from each other as the book says. Of course, the book says that you have to spread fertilizer when planting. But I didn't find any fertilizer in the mall. So it's left to the gardener here. Fortunately, it is written in the book that the vitality of this thing is extremely tenacious, and you can survive by digging a pit and burying some soil......

And the way of 'scientific planting' in later generations~ can only be ignored.

The seeds of that pumpkin are also processed. It's just that pumpkin seeds need to be soaked in warm water to 'sprout' before planting. That's what I said in the book I brought. But in order to save trouble, I just dug a pit and buried it. As for whether it can sprout~ It depends on the ability of the gardener here......

After planting these things, I suddenly realized that the greenhouse was too big this time, so I hesitated for a moment and took out a lot of seeds from the mall. I thought, it's an experimental plant anyway, so let's let the gardeners here try a few different plants! If they are all planted, then I can have more 'mouth blessings'! Because what I took out this time is watermelon, cucumber, cantaloupe, melon and other seeds! There is no special seed counter in the mall, but these fruits and vegetables are sold in supermarkets. So I took the seeds straight from the fruit and tried to plant them. Anyway, I've been craving some fresh, freshly picked fruits and vegetables...... To be honest, if I hadn't been too busy lately, I would have built a greenhouse in my village again to grow these fruits and vegetables that I like.

There are many other fruits and vegetables, but I don't know if the rest can be easily grown. Apples, for example, have to grow into apple trees and then grow for a few years before they bear fruit.

In addition, in Datang, I didn't find the kind of apple that was eaten in later generations, but there was a fruit similar to 'sand fruit'. It's just that the taste is not good, and it is sold as food......

After I struggled to find all the plants I thought I could grow in the supermarket, and then struggled to fill up the oversized greenhouse, I began to regret why I had built such a large greenhouse. It took me all day just trying to fill up!

As a result, I stayed overnight in the palace. Of course, I was arranged to camp in the courtyard of the princess hall...... In other words, if you stay in the palace in this era, isn't it a special hall? Last time, I also made a special inquiry about the process of biting gold, and I heard that sometimes the palace held banquets to entertain ministers, and some people would be kept in the palace when they were drunk, but they were carried to a special side hall to rest. In addition, sometimes when discussing important matters overnight, some ministers who were too tired would be left to rest, and they would all be sent to the side hall...... Like me, I am the only one who has been kept in the princess palace and still lives in the princess palace...... Although it is camping in the courtyard of the princess palace.

After the next day, when I was busy with these greenhouse things, I just wanted to say goodbye to His Majesty and continue my dream of 'wanting to fly higher'. I heard that His Majesty kept me again, and then called Cheng Biting Jin Li Tao and the first boss under the emperor who had met several times, Changsun Wuji. When he took me to the main hall, he realized that the main reason why the emperor urgently asked me to enter the palace this time was not the problem of food and greenhouses! That turned out to be an excuse. The real purpose of looking for me turned out to be about gunpowder, and the weapons that used to destroy the enemy at Niangzi Pass~ Of course, it wasn't that rough quality cannon. It was the last blow that I stuffed all the gunpowder into the barrel of the cannon, and then made my own blasting canister...... It turned out that after the last incident outside the Niangzi Pass was reported to the imperial court layer by layer, whether it was the Ministry of Industry or the military boss, everyone who could see the record of this battle was shocked by the introduction of the great power of this 'blasting cylinder' on the fold.

At that time, many people were eager to summon me into the palace on the spot, and then forced me to ask me how I got this 'heavenly thunder' artifact.

But fortunately, after His Majesty and the boss of the Ministry of Industry at that time read the details in detail, they prevented this from happening. Because I had already handed over the formula of gunpowder to the imperial court, although the Ministry of Industry did not pay special attention to it, it also created a new department to study these gunpowder secretly. And when I finally filled all the gunpowder and stuffed the cannon barrels, the defenders of Niangzi Pass saw the whole process of me. So after reporting this part, the emperor and the bosses of the Ministry of Industry basically understood how this 'heavenly thunder'-like artifact was made......

It's just that after many attempts and experiments, these people found that although this 'blasting canister' is very easy to make, and after making it, it can exert a certain amount of power, and the sound is huge. However, after the people of the Ministry of Industry personally tested it, and specially brought in the guards of Niangziguan who were present at the time, they found that no matter how similar they imitated the appearance, the power of the 'blasting cylinder' was very small. The defenders who were present at the time said that this was only half the power of the one I used myself......

It is precisely because of this that the people of the Ministry of Industry found that they could not imitate the same power, so they reported it to the imperial court...... And the emperor in front of me, Cheng Biting Jin Li Tao and the eldest grandson Wuji, their main purpose is for me to personally make a 'blaster' that can reproduce the scene of the battle at Niangzi Pass...... Oh yes! This thing is now named "Thunder" by the eldest grandson Wuji himself......

After I said yes, I was taken to a secret location in the depths of the palace. After arriving here, I learned that because of the matter of Niangziguan, the importance of gunpowder has been paid special attention by the imperial court. That's why this small department, which was specially removed from the work department, was rearranged to the depths of the palace. Anyway, when I saw that this 'handicraft workshop' of 'making dangerous goods' was actually opened in the depths of the palace, I was shocked by the person who came up with this idea~ Who is so bold? Came up with the idea to set up such a dangerous department in the palace? Aren't they afraid of an accident one day? In particular, when I found out that there was not only a workshop for mixing and making gunpowder, but also a large storage warehouse, I was completely frightened...... If there is a real accident, I estimate that half of the Daming Palace will have to be destroyed......

After a cold sweat, I hastened to express my concerns to His Majesty the Emperor, as well as the danger of this workshop and storage warehouse. Then I saw the people who were in a cold sweat on the spot, except for His Majesty, who was quickly escorted away by the guards, only the eldest grandson Wuji's face had the most cold sweat...... It wouldn't be his idea!

"Your Majesty, even if it is in ~ my division, this kind of workshop is arranged in a remote area far away from people!"

As a result, I was delayed for another day for the removal of the workshop and the repository from the palace. However, I also took the opportunity to return to the warehouse, in addition to taking a look at the progress of the transformation of the 'wooden kite' by the Mandarin Duck and the Duck and Nie Xiaoqian, my main purpose was to get the few scrapped cannon tubes that were used last time when I was in Niangzi Pass. At the time, I just took it back and threw it in a corner. Now it's time to use this to make another one, the 'blaster', and when the gunpowder workshop is moved, I'll take it and hand it over to them, and I should be considered done!

Another day wasted in the palace. Among them, the vegetable greenhouse in the Imperial Garden let me go over, but I only gave a suggestion for the temperature control of the greenhouse, and also took out a temperature and humidity meter. After all, the seeds have just been planted, and now they can't even be watered with more water.

Then I was called to the lakeside pavilion in the garden by a group of princesses and princes~ I worked as a barbecue master for these princesses and princes for more than half a day...... I now suspect that the main purpose of arranging for me to enter the palace is to make me a cook! Otherwise, why did you arrange for me to live in the princess palace? Camping there, the first thing I do every morning is to make breakfast for a bunch of princesses and princesses who come over to eat! I've changed a few tricks, and this morning I used bread, sausage, bacon, and omelette to beat them...... As a result, it was just after noon, and he was called to the Royal Garden by this group of people in the name of the vegetable greenhouse, and then he worked as a barbecue master for more than half a day. Among them, His Majesty the Emperor came over for a barbecue......

Anyway, didn't I leave some seasonings, seasonings, and spices? And there is also an imperial chef who came to my restaurant and asked the small pot and spoon to help teach them a lot of cooking skills! Why do you have to rely on me to do it myself?

After the gunpowder workshop was moved, I was freed from being a cook. Now the palace has cast a shadow on me. This is simply a trick on me to come and work hard!

It was only when I saw the 'blasting canister' made by this newly established department that had just been renamed the 'Ministry of Industry and Fire'. I was actually surprised.

These people have made the exact same structure as the one I used last time in Niangzi Pass without seeing the real thing! Even the twisted arc of those cannon barrels has been perfectly restored......

When I took out the 'blasting canister' that I had just made in the warehouse, I found that it was almost identical except for the texture of the shell! These people's craftsmanship is too good!

"Oh! It turned out to be rolled out of copper plates! "I looked at the material, and realized that the craftsmen here did not have my steel plates, so they used a double-layer method of copper and iron plates to roll out the barrel, and then imitated the arc, and filled it with gunpowder and fuse......

It was only when I saw that they tried one. I found out that the power of this thing is not ordinarily small! The 'blasting canister' that was ignited and dropped from half of the city wall was only very loud and scary, except for a few fragments, but it was not at all as effective as the use of the 'blasting canister' when I was in Niangzi Pass. I can't even reach half of the power! It is estimated that if there is also that kind of white rhinoceros attacking the city below, then the blasting canisters imitated by these craftsmen are estimated to not be able to handle even a rhinoceros......

I gave the blaster I made yesterday to the craftsmen and let them try it out, and it was only then that I realized that the power of my one was obviously much more powerful than the one they copied. Not only did it blow up more than half of the city wall, but even the shock wave caused by the blasting could be clearly felt by us hundreds of meters away! Of course, the sound made this time is similar to that of the imitation......

"What's going on? Could it be that ~ your gunpowder recipe is wrong? Is it mismatched? "Confused, I personally prepared a pack of gunpowder from the materials here, and then took out the last scrapped barrel from the warehouse. After the charge is made into a blasting canister again.

This test explosion turned out to be the same as the first time, and it was still amazingly powerful~ and even more outrageous this time. After the blasting, it didn't even blow up the scrapped cannon barrel! After ignition, the enormous pressure of the gunpowder combustion did not open the barrel, but flattened the part of the barrel at one end. It's just a salute with empty shells...... It was also fortunate that stone shells were not added to it, otherwise this time it would have caused accidental casualties......

"I'll go! What the heck? Mismatched gunpowder? That's not right! I'm obviously configured according to the standard formula of 'one nitrate, two sulfur and three charcoal'! Could it be that there is a problem with the raw materials here? ”

With doubts, I asked the craftsman to find new saltpeter sulfur and charcoal powder again, and then reconfigured one, put it into the cannon tube that had just been used once, and sealed it again and ignited it~ It turned out that this time it was the same as last time, and the less powerful one was not even propped up from the scrapped cannon tube......

I tried to reload it again with gunpowder from the warehouse, and this time it turned into a powerful 'blasting canister'...... Is it really a problem with the material?

With curiosity, I took out all the gunpowder that was left in the warehouse, and then I thought that the raw material of this gunpowder was obtained from the divine doctor Sun Simiao. Is it because of this? Is it the reason why the raw materials sent by Daomen are purer?
