The construction of the grenade is relatively simple, and it is a pineapple shape with pre-exploded fragments. Originally, Yang Wenli also wanted to use the advantages of the devil's Taisho 11-year-old grenadier to fire grenades, so that the grenade would fit in with the grenade he was going to develop, but after thinking about it carefully, he didn't want to use it.

The devil's grenadier is a pull-hair type, and a separate propellant pack is needed to fire the grenade, which is more troublesome and has a high risk, such as the temperature of the chamber pressure is too high, and the grenade may explode in the grenadier.

Therefore, the grenade envisioned by Yang Wenli now is enough as long as it is easy to hold with one hand and weighs about three catties, which is much simpler and has no special requirements for appearance.

After thinking about it, Yang Wenli made the mold himself, because it was an experiment, Yang Wenli didn't have time to wait for the clay mold to dry, he dried it with a furnace fire, maybe there will be bubble eyes and cracks on the inner wall, but it does not affect the experiment.

When the projectile body was cast, Yang Wenli found that he had forgotten to make an important tool: a handmade wire machine, and a full set of fitter equipment.

However, the problem is not big, these jobs are very simple, he has used them in his previous life, the difficulty is in the material, there must be a high hardness of high-carbon steel, which is not difficult for Yang Wenli, who has mastered a full set of carburizing and fireing technology.

There were too many things to do, so he commanded his slaves to work separately, and he was responsible for technical guidance, which significantly accelerated the speed of development.

After China's first set of fitter tools was developed, Yang Wenli looked at the dozen or so gadgets in front of him, and was excited, including a vice, a manual tapping machine, a round wrench, a frustration knife, a saw bow, a rectangular ruler, and a scribing reel...... And so on, these things seem simple, but they are the foundation of industry, so to speak, without these simple hand tools, there would be no modern industry in later generations.

He finally changed the history of China, and from then on, China will go further and further on the road of industrialization, far ahead of the world.

However, Yang Wenli, who was nostalgic, could only temporarily stop his work, wash his hands and go home, because there were still five days to go before the New Year.

Although it is on this large island in eastern Liaodong that there is a shortage of materials and the heavy responsibility of defending the Tatars, the Chinese are looking forward to a lively and lively New Year, and he must also conform to the people's feelings.

Changsheng Island is very large, and it takes two days just to notify the heads of various ministries to hold a meeting, so Yang Wenli will notify everyone to hold a meeting five days before the New Year, which is just right.

Two days later, in the morning, Yang Wenli was still sitting on the warm kang in the house to practice meditation, this method needs to be quiet, but there is no need to practice the body and mind as hard as Buddhist zazen, how to be comfortable, how to come, zazen is just its form.

Xiao Yan'er saw that Yang Wenli couldn't talk to her, so she felt bored and decided to walk around and take a walk, but when she walked to the hall, she couldn't help but shout: "Wow! What are you doing today! So hot! ”

It turned out that the heads of all the ministries would come to the meeting today, so a few large pots of charcoal fires were lit in the hall, which seemed warm as spring, and at this time there was no one in the hall, and everyone was busy with things.

Xiao Yan'er decided to sit down and play here for a while, and when Xianggong finished practicing, she went back to the room.

She stood on tiptoe, holding the armrests of the Taishi chair with both hands, and skillfully sat on her special chair on the right side of the head, just as she moved her buttocks and wanted to sit up straight, a person came in outside.

The person who came was Liu Xingzuo, he had just joined the Black Armor Army, and his qualifications were relatively low, so as soon as he got Yang Wenli's order to hold a meeting of the heads of various departments, he came early.

The main thing is that he rides a horse, so although he is far away in Beixunkou, he also arrives earlier than the others, which is exactly what he thinks.

He rushed early, and the other chief officers did not come, but he saw that there was a little girl about seven or eight years old sitting on the upper chair.

Liu Xingzuo had only been to the Commander's Mansion once in total, and he had never seen Xiao Yan'er, so he hurriedly reminded kindly: "Little sister, you can't sit there, hurry up and play somewhere else." ”

"Bold" Xiao Yan'er exploded when she heard this, she didn't want to hear anyone say that she was a child, which did not match her identity, so she blushed, her apricot eyes widened, and she scolded sharply.

"Who are you? Do you know who I am? ”

"...... you?"

Liu Xingzuo realized that he had done something bad with good intentions, this little girl was so powerful, there must be a source, just when he was speechless, Yang Rentian's brothers who defended Nanxunkou arrived, Nanxunkou was close to the Commander's Mansion, and it was rude for them not to come earlier.

Yang Rentian's brothers, who had just come in, saw their wife's eyes wide with anger, for some reason? But he hurriedly turned over and bowed and saluted: "Madam"

"Ma'am? Oh, my God! I actually called her little sister just now, it's too bad, it's not good to get off the stage. Liu Xingzuo felt miserable.

"Rentian, who is he, he is so unreasonable!" Xiao Yan'er was angry, so she asked Yang Rentian in a coquettish voice.

He ...... He is the commander of the first army of the servant army: Liu Xingzuo is the chief flag officer. Yang Rentian had to reply truthfully, others may not know, he doesn't know the weight of his wife, and even the Grand Commander has to let her have a few points.

"Madam, the humble position is not Taishan, please forgive Madame!" Liu Xingzuo was so frightened at this time that he saw that the lady's anger had not subsided, so he quickly knelt down and begged for mercy.

Ever since Yang Renyue fought with his brother Liu Xingzhi and tried his hand at it, he deeply felt the strength of the Black Armor Army, and the force was terrifying, so let's put it this way! At this time, a few people in the house, any one person can pinch him to death like an ant, do you think he is afraid?

"Humph! Forget it, remember your ignorance, spare it for the time being, and get up! Xiao Yan'er has been in the top position for a long time, although she is young, she has her own majestic bearing, she snorted coldly, and commanded Liu Xingzuo in an experienced tone.

"Mrs. Xie!" Liu Xingzuo thanked him again, and then stood aside with his hands solemnly.

"Sit down, everybody! What's so close today? After letting Liu Xingzuo go, Xiao Yan'er waved her little hand to let everyone sit down like a little adult, and asked out loud.

"Mrs. Xie"

Several people bowed and thanked them, and after sitting down according to their positions, Yang Rentian, who was sitting first on the left hand, replied: "Two days ago, the commander called me to wait for a meeting today, thinking about the New Year. ”

"Oh! It's going to be the New Year again! Well! It's time to hold a meeting to arrange it, now that the number of black armor soldiers has exceeded 10,000, it will not be easy to celebrate the New Year. ”

Xiao Yan'er is like a little adult, old-fashioned, which makes people laugh when they hear it, but her status is noble, and no one dares to offend, so she has to endure it.

After a while, the rest of the chief officials also came one after another, and they all greeted Xiao Yan'er who sat on the top of the house, Albugu, his luck was much stronger than Liu Xingzuo, he came with several chief officers of the logistics department, and greeted Xiao Yan'er with several senior officials, but he did not offend Henwei.

"Good! Everyone is here, salute people, go to the back and call the commander to come to the meeting. Xiao Yan'er saw that it was a New Year's party, so she didn't want to avoid it, she was the master of the house as a lady, and ordered Yang Li, the leader of the slave soldiers, to be humane.

"Yes, madam," Yang Li bowed and went to the backyard to call Yang Wenli.
