Zhu Xiongying sent the flintlock pistols back to the arsenal and selected two of them as the main mass production.

One is a long pole, which is mainly used to equip the army, and when fighting, shoot at the enemy from a distance.

The other is a short-shot, flintlock pistol that is suitable for close-range firing and is mainly used for melee combat or self-defense.

In the next few days, Zhu Xiongying went to the arsenal several times to personally guide and supervise them to mass-produce the two flintlock pistols.

The other side.

Zhu Di, who was in Beiping, was very excited when he received a letter from Lao Zhu.

At the beginning of April, Lao Zhu issued an imperial list to the whole country, announcing to the world that it was Zhu Xiongying, the emperor's grandson, who proposed that smallpox could be immunized with cowpox vaccination.

At that time, Zhu Di was still very curious about how the little nephew, who was only eight or nine years old, could understand such a magical method.

Zhu Di learned that Zhu Xiongying was canonized as the emperor's grandson, and he wanted to respond to Tianfu to come to see him, but Beiping is a military powerhouse, and it is far away from Yingtianfu, so he can't go back if he wants to.

He didn't expect that in less than a month, his nephew Zhu Xiongying brought another surprise to the Ming Dynasty.

Lao Zhu didn't tell him much about Zhu Xiongying in the letter, but only told him that Zhu Xiongying had invented a flintlock pistol, which was conducive to strengthening the strength of the Ming army, and asked him to come back and discuss the formation of the Shenji Battalion together.

Zhu Di hurried back.

After seeing Lao Zhu and Zhu Biao, I learned from Lao Zhu's mouth that Zhu Xiongying was seriously ill, and after waking up, he said that he had gone to the afterlife, so he had the magical inventions of cowpox inoculation and flintlock pistol.

When Zhu Di heard this, he was surprised and delighted.

Fortunately, the serious illness didn't kill Zhu Xiongying, otherwise he wouldn't even be able to see this nephew for the last time.

Zhu Di is only 14 years older than Zhu Xiongying, and he is only 22 years old this year.

Before getting married, he often took Zhu Xiongying to play together, and their relationship was not only uncle and nephew, but also like brothers.

Zhu Di heard that Zhu Xiongying often appeared in the back garden recently, so he wanted to go over to find him.

Zhu Xiongying came back from the arsenal and saw Zhu Di as soon as he arrived in the back garden.

It was a man with a strange appearance, wisdom and courage, and a leader temperament.

The climate in the north is dry, not as moist as the south, and after two years of not seeing him, the fourth uncle looks a lot more mature, and his small beard has also grown.

People say that they are the most ruthless emperors, but in Zhu Xiongying's memory, the fourth uncle is not like this, he attaches great importance to feelings, respects Zhu Biao, and listens to Zhu Biao's words.

Among the uncles, he is the one who loves Zhu Xiongying the most.

"Fourth uncle!"

Zhu Xiongying shouted loudly and strode towards Zhu Di.

When Zhu Di saw Zhu Xiongying, he laughed in surprise and strode towards him.

"Oops! I haven't seen you for two years, Xiongying has grown so big, and he is really going to become an eagle! Haha......"

Zhu Di said, walked up to Zhu Xiongying, hugged him as before, and then said with a doting smile:

"I've really grown up a lot, and the fourth uncle won't be able to hold you anymore! What do you think? Do you miss the fourth uncle? ”

Zhu Xiongying pulled Zhu Di's mustache and smiled.

"Of course I do! That's why I asked my grandfather to call the fourth uncle back! ”

Zhu Di was very happy and laughed.

"You kid is really capable now, not only to solve the problem of smallpox, but also to build firearms!"

"Hehe, it's just a coincidence. Fourth uncle, are your arms sore? Put me down! ”

Zhu Xiongying was held by a big man like this, which was somewhat awkward, although in memory this man was one of his closest people.

Zhu Di put Zhu Xiongying down and sighed.

"Xiongying, I didn't expect so many things to happen to you in the past month. Fortunately, God favored you and sent you back! And let you bring back so many novel things, God bless us Daming! ”

Zhu Xiongying smiled.

From the fourth uncle's tone, it is not difficult to hear that the grandfather has not yet told him about the death catastrophe on the first day of the fifth month.

It would be better if he didn't worry.

The two were chatting, and Zhu Yunxi, accompanied by the eunuch Liu Zhi, came over.

"Brother, you're back!"

The eunuch Liu Zhi recognized Zhu Di, and he quickly knelt down and saluted.

"Slave maid to meet His Royal Highness King Yan!"

"No need to be polite, get up quickly!"

Zhu Yunxi looked at the strange man in front of him with a confused expression.

The year before last, when Zhu Di left Yingtianfu to take up the domain in Beiping, Zhu Yunxi was only two years old, and he was a little kid who had just been able to walk for a long time, so he naturally didn't remember Zhu Di's appearance.

Seeing this, Zhu Xiongying touched Zhu Yunxi's little head, and introduced with a smile:

"Little brother, this is our fourth uncle, call it fourth uncle!"

Zhu Yunxi hurriedly saluted Zhu Di.

"Nephew Yunxi, meet the fourth uncle!"

Zhu Di smiled, happily picked up Zhu Yunxi, and touched his little head.

"Oops! Time flies! I haven't seen you for two years, and Yun Xi has grown so big! ”

Zhu Xiongying still had something to talk to Zhu Di, so he said to Zhu Yunxi:

"Little brother, you go elsewhere to play first, my brother still has something to do, I'll look for you later!"

Zhu Yunxi nodded obediently, and then left with the eunuch.

Looking at the background of his departure, Zhu Di sighed.

"Yun Xi is also pitiful, he was born without a mother. It's rare for you brothers to be so well-behaved and sensible, if your mother is still here, how nice it would be! ”

Hearing this, Zhu Xiongying's heart trembled involuntarily.

He asked softly:

"Fourth uncle, can you promise me one thing?"

Zhu Di smiled and patted Zhu Xiongying's shoulder.

"Silly boy, what do you think? Don't say one piece, it's a hundred, and the fourth uncle will promise you! ”

"Thank you, Fourth Uncle!"

"What the hell is going on? Say it quickly! ”

Zhu Xiongying looked at Zhu Di with a serious face.

"Fourth uncle, if there is an unimaginable situation in the future, please take care of Yun Xi for me, okay?"

Hearing this, Zhu Di was taken aback, and suddenly felt a chill down his spine.

He knew that Zhu Xiongying had gone to the afterlife in his dream and learned about something that had not yet happened.

"Xiongying, this is so good, why did you suddenly talk about this? What happens behind this? What happened to Yoon-hee? ”

Zhu Xiongying shook his head.

"Fourth uncle, don't be nervous! Even if those things happen, they are under control. You will become one of the heavyweights who will influence the development of the Ming Dynasty, and taking care of Yun Xi is something that you can easily do. ”

Zhu Di was even more confused, what did this nephew want to say?

Zhu Xiongying was also a little helpless, he couldn't tell this fourth uncle that he would rebel and seize the throne in the capital twenty years later, right?

"Fourth uncle, don't ask so much, just promise your nephew!"

Zhu Di smiled dotingly.

"Good! Good! Good! Fourth Uncle promises you! I don't know what you're thinking! ”

"Haha! Fourth uncle, tomorrow morning I will accompany you to the arsenal in the capital and take you to try the flintlock pistol, how about it? ”

Hearing the flintlock pistol, Zhu Di instantly became interested.

"Good! That's what I mean! ”
