Good artillery uses good steel, so Chen Fang's first thought is the Ordnance Supervisor, the steel smelted here is the best in Datang at this time, in fact, in the whole world, Datang's iron-smelting technology is also the top.

This is not boasting, there are still so many famous knife-making masters in later generations who regret that they can't make Tang knives, just because the basic smelting technology can't be reached.

In fact, many techniques of the ancients cannot be restored by later generations, such as weaving, the plain yarn clothes of the Han Dynasty, which cannot be imitated by later generations, and the Tang knife is also, and in the Qin Dynasty, the sword casting technology of the Qin Dynasty, later generations can only sigh its exquisiteness.

For example, the anti-corrosion and anti-rust technology used by Qin Jian was only studied and used in modern times in later generations. And the exquisite structure of its sword body, the copper-tin ratio in bronze, is still amazing to later generations.

Chen Fang finished painting the basic structure of the artillery at this time, and then sighed, it is still the superb painting of his predecessors, and compared with his predecessors, this painting is simply graffiti.

A senior who can draw a map of the world by hand, Chen Fang thinks that he cannot be compared.

At this time, the drawings have been drawn, although they are not satisfactory, and they will be used.

Chen Fang handed the drawings to the ordnance superintendent, and the ordnance superintendent looked at it.

"Can the ordnance supervisor be made here?"

"Master Horse, this casting is fine, but this thing is the first time I've seen it."

"As long as the casting is fine, remember, use the best steel. Also, are there any raw materials for black powder here? ”

"Master Pony, there is, but this thing is a little dangerous to prepare."

"You prepare, I'll come and get it in three days."

"Yes!"

Chen Fang only cast cannons at this time, and did not make muskets, because the difficulty of casting cannons is not high, even if there are no notes left by predecessors, the most basic artillery Chen Fang can also make. However, with the notes of his predecessors, Chen Fang directly cast the breech cannon.

The reason why he didn't make muskets was because Chen Fang didn't plan to make basic guns like muskets and forecharge flint guns, he planned to cross them directly and make more sophisticated rear-charge flint guns.

The meaning of the word flint is to use the flint on the hammer to produce sparks and ignite gunpowder, and the earliest way to ignite gunpowder is to ignite with an arquebus, which is called an arquebus.

When she left the ordnance prison and returned to the Tang workshop, Wu Meiniang had already returned, and Chen Fang saw that she was a little haggard and resting on the quilt on the bed, sitting beside her, and rubbing her shoulders.

"Chen Fang, where did you go?"

"I was in the ordnance prison just now, and I was delayed for some time."

"Accompany me to Linqing'an Pavilion!"

"Good!"

Chen Fang just answered, and suddenly heard a commotion outside, and several maids were calling His Royal Highness, as if they were chasing His Royal Highness.

"Xiaolan, what's going on outside?"

"It's Your Royal Highness, Your Royal Highness is running away with the little princess in your arms!"

"Taiping hugged Sisi and was running?"

Xiaolan nodded, Chen Fang was startled, Wu Meiniang was also frightened, at this time the two hurriedly went out of the yard, looking for the direction of the sound and chasing after it.

Taiping was holding Xiao Sisi at this time and had already run to the lotus pond.

"Taiping, don't mess around, hurry up and put Sisi down!"

"Sister Huang, I took Sisi to the lotus pond to see the lotus flowers, where is the nonsense."

"Sisi is still young, what if I fall into the lotus pond?"

Princess Anding had already chased to the lotus pond at this time, and the royal sister ran too fast, and she was out of breath at this time.

"Hurry up and give Sisi to the imperial sister!"

"No, I'm going to play in the lotus pond with Sisi!"

At this time, a large number of maids had already chased after them, but no one dared to come over and take Xiao Sisi back from Taiping's hands.

Chen Fang finally rushed over at this time, and several maids hurriedly made way for the horses.

Chen Fang had already seen Taiping holding his little daughter, and he also knew the specific situation at this time.

It turned out that Anding and Taiping came to Tang Gongfang today, and as soon as they came, they ran to Yiyang to tease their little niece, who knew that Taiping was on a whim and wanted to take Xiao Sisi to see the lotus, Yiyang and Anding naturally couldn't let her mess around, just said no, I saw Taiping hugging Xiao Sisi and running out, and then, it was a scene at this time.

"Alright, you all stand down!"

Many maids retreated at this time, and Chen Fang, the two princesses, and their infant daughter were left here.

Taiping didn't let go of his little niece at this time, and An Ding and Chen Fang were shocked to see it. How about this in case of falling!

Wu Meiniang had also rushed over at this time.

"Taiping, don't mess around, hurry up and give Sisi to the colt!"

"No, Queen Mother, I just want to take Sisi to see the lotus."

"Niangniang, I'll accompany His Royal Highness to take Sisi to see the lotus flowers!"

Taiping hugged Sisi and didn't let go, no one could help it, Chen Fang looked at her, and calmed down Tai first.

"Pony, I'll go too!"

An Ding is not at ease, he has to follow at this time, Chen Fang nodded.

For the boat by the lotus pond, Chen Fang took the tether on the shore, Taiping and Anding sat on one side, and Chen Fang sat on the other side.

Chen Fang carefully kept the balance of the boat, this must not be careless, his daughter was still in the arms of His Royal Highness.

This happened today, and it seems that it will be guarded against in the future, fire prevention, theft prevention, and peace.

Chen Fang rowed the oars, Wu Meiniang was not at ease, and let Xiaolan who came with her row a small boat and follow the horse's boat.

On the boat, Princess Anding was so talkative, and finally Taiping handed Sisi to her imperial sister.

"Sister Huang, what did Sisi call me?"

"Call Auntie!"

Chen Fang said there that His Royal Highness is the sister of the Emperor Yiyang, so she is naturally Sisi's aunt.

"Sisi, call Auntie, Auntie will give you candy!"

Taiping took a candy from his purse, which was naturally supplied to the palace by the Tang Workshop.

"Imperial sister, Sisi can't speak yet, how can I call you aunt. Besides, she can't eat sugar now. ”

"And what does she eat?"

An Ding looked at his imperial sister, and his cheeks were slightly red.

At this moment, Sisi cried.

"Chen Fang, Sisi is crying!"

"She's hungry!"

"Ahh What to do, colt? ”

"Let's hurry back and let His Highness feed her."

Xiao Sisi was crying more and more at this time, Chen Fang turned the bow of the boat, just turned his head, but the little daughter stopped crying, Chen Fang turned around and quickly let go of his eyes.

"All right, colt, she won't cry."

"Let's go back quickly!"

Chen Fang said a word, rowing a small boat, passing through layers of lotus leaves, at this time Taiping folded a lotus, and saw his imperial sister holding Sisi and feeding her.

When the boat arrived on the shore, Chen Fang took his little daughter from Princess Anding's arms, and saw that Anding was blushing at this time.

"Thank you, Your Highness!"

"I just listened to her cry so much, I learned from the imperial sister..."

Chen Fang hugged Sisi, rushed to Yiyang's residence, and handed Sisi to Yiyang, so that he could be relieved.

told Yiyang that as long as Taiping comes in the future, he must hold Sisi well, and he must guard against Taiping.

came out at this time, accompanied the charming lady to the carriage, and he also had to accompany the mother to Linqing'an Pavilion, Wu Meiniang's heart, at this time, Li Hong was naturally the most important.
