Where the gunpowder bomb exploded, there were craters, and around the crater were wooden men and grass people who were shattered by shrapnel.

Needless to say, this power is better than all current weapons. Even with armor on your body, you will inevitably be injured and killed.

"Qi Lin, can you make this gunpowder bullet small and throw it out with manpower?" His Majesty Li Er's improvement made Xu Qilin admire him again.

What guys are these? When it comes to fighting and killing people, they all have IQs occupying the high ground. Before he could say that, he was going to do the grenades to launch grenades!

"This—" Xu Qilin pondered for a moment and said, "It is natural that there is no problem to be a small gunpowder bullet, but to ensure its power, I think the weight must be at least two or three kilograms. It is necessary for soldiers with large arms and round waists and overwhelming arms to throw such a heavy gunpowder bullet to a safe distance."

After pausing, Xu Qilin then added: "If it is used for city defense, this small gunpowder bullet designed by His Majesty should be more convenient and easier to use."

Grenadiers did not become a branch of the European Army until the mid-18th century. Because the grenades at that time were relatively large in size and weight, the ones who could become grenadiers were what Xu Qilin said to be big and round waists.

If used for city defense, there are not many requirements on the body. If you light it, throw it down, anyway, it won't blow you up.

His Majesty Li Er nodded and did not ask any further. But he had already made a decision that the gunpowder would be handed over to the weapons supervisor to develop new weapons, enhance the combat power of the Tang army, and realize his dream of sweeping the eight deserts and surpassing the emperors of all dynasties as soon as possible.

"Is it a weight of two or three pounds?" Cheng Yaojin probably came to make fun of it. He picked up a stone on the ground, weighed it, shook his arm, and threw it out with force.

He is really smart and Xu Qilin predicts that this old guy can throw about 30 meters, which is an absolute safe distance.

"Zhijie is very strong, hahaha." His Majesty Li Er laughed and said, "Although the strong soldiers in the army are not as good as you, you can still organize a grenade force with careful selection."

Everyone agreed, but they also felt that with the current strength of the Tang army, the grenadiers might not have much use.

Xu Qilin also believed that these new weapons only increased His Majesty Li Er's confidence, and the biggest possibility was to play a role in conquering Liaodong. As for fighting Gaochang and fighting the Western Turks, it seemed that there was no chance to use it.

As for Tubo, it was the enemy decades later, and there was no need to worry too much now. Even if you have to take precautions, managing Longyou and Hexi is a long-term solution.

"Leave the gunpowder formula and stone thrower drawings to the weapon supervisor, and let them ask you if you don't understand." His Majesty Li Er looked at Xu Qilin with admiration, and explained before leaving: "I am very satisfied with this exercise, and there will be rewards soon."

Xu Qilin hurriedly bowed to thank him and sent His Majesty Li Er and others to leave.

Li Jing, Li Ji, Cheng Yaojin, and Hou Junji were also kind and close. After saying hello, they left.

Everyone can see that Xu Qilin is favored. Of course, there are his young age and simple background, his interpersonal relationships without such complex interpersonal relationships, and his ability to use His Majesty Li Er with confidence.

After seeing off His Majesty Li Er, Xu Qilin's heart fell to the ground and completed another major event. He could celebrate the Lantern Festival with peace of mind.

As for managing Hexi, it’s not a matter of rush, just take it slowly! Anyway, he really needs to study it carefully before he can produce a more qualified report.

……………………

Xu Qilin asked someone to clean up the exercise venue. After explaining the work, he took a few servants back to Chang'an. After returning to the city, he went straight to the palace.

It is not about reporting something to His Majesty Li Er, but about notifying the elder sister that his elder brother Xu Qiqiu was about to get engaged to the Chen family.

According to the marriage process at that time, the procedure for naming and asking names has been completed. The following is Naji, who is about to be formally engaged.

The so-called "naive" means that the man asks a matchmaker to propose marriage to the woman's family. After the woman's family expresses her agreement in principle, the man will give the woman a gift symbolizing auspicious meaning.

Asking for a name means combining the names of both parties with their birth date and eight characters on a red paper called Geng Tie, and put them in front of the gods or before the ancestors to divine good or bad luck to determine whether the man and woman are suitable for marriage.

Simply put, it is to combine the eight characters to see if the two will be in conflict or incompatible, and avoid unsuitable marriages in advance to prevent the two families from having a bad luck in the future.

If the eight characters are in harmony, the marriage between the two parties will take the formal process. If nothing unexpected happens, the marriage will be completed.

As an elder in the family, Xu Hui, as an elder, must notify him. According to Xu Hui's temperament, he will most likely not be complicated, but the meaning of respect must be expressed.

It was more convenient for Xu Qilin to walk around the palace often, but Xu Qilin was not even fourteen years old. The guards at the palace gate asked a few symbolic questions and then let Xu Qilin enter the palace.

Since he had a serious business and had just met His Majesty Li Er, Xu Qilin went straight to Bingxia Palace to meet his sister.

It’s the New Year, Xiao Zhao has a holiday, and His Highness the Princess doesn’t have to come to study anymore. Apart from a gathering of concubines, Xu Hui enjoys the tranquility of these times.

The hall is warm, without any fireworks, making people feel comfortable and comfortable.

Xu Hui leaned halfway on the sofa, holding the book and reading it. He stretched out his slender hands and took melon seeds from the fruit plate next to him from time to time, but he was graceful and elegant.

On the hanging bird stand was a trained parrot bought by Xu Qilin. It was originally quite leisurely, but suddenly tilted its head and shouted: "Auspicious, good luck."

Xu Hui sat upright, knowing that the bird cried, he probably heard footsteps and knew that someone was coming.

Following the palace maid who was reported, Xu Qilin stepped in. The so-called notification was just a formality.

"It's my brother!" Xu Hui smiled, and returned to his original relaxed and comfortable posture, saying, "Are you going to demonstrate something new to His Majesty outside the city? Is this done?"

Xu Qilin nodded, sat down, and said with a smile: "The exercise is completed, Your Majesty is very satisfied and said there will be a reward."

Xu Hui smiled and said, "I am still capable. If I continue like this, I will become a high-ranking official before I become an adult."

Xu Qilin took the tea handed over by the palace maid and drank two sips, and said, "I'm here, I'm going to tell my sister about the happy event."

Oh, Xu Hui raised her eyebrows and said, "Besides the reward, there are any other happy events, come on."

Xu Qilin smiled and said, "It's my brother's happy event..."

After listening to Xu Qilin's story, Xu Hui smiled and said slowly: "Even if Qi Qi is optimistic about it, you don't think there is any problem. Of course, there will be no problem here. Qi Qi is going to join King Ji and then go again after becoming a relative, so he can also avoid being alone in a foreign land and no one will take care of him."

Xu Qilin said: "Although the Chen family is not prominent, it is considered innocent. I also know the Chen family's wife, who is a virtuous and polite person. She is not unfamiliar with her elder brother, and this marriage should be good."

After pausing, Xu Qilin continued, "If my sister agrees, I will tell my elder brother to hurry up and strive to get married in the first lunar month. Then, I can go to Xiangzhou to work."

"First month--" Xu Hui calculated the time and said, "You must hurry up." As she said that, she stood up and smiled, "When I find a gift for the bride. As for money, if you have my younger brother, you will definitely not be short of your family."

Xu Qilin said: "This is not urgent, sister doesn't have to worry."

"Since there is nothing else, please sit down." Xu Hui moved slowly, went to the dressing table with great interest, opened the box and searched, but didn't listen to Xu Qilin.

Xu Qilin shrugged, drank tea, ate fruit, and watched his sister work hard.

Xu Hui was both happy and excited when there was such a big happy event at home. Without her parents, she, who was a sister, could not leave the palace, so she naturally had to pay great attention to this gift and express her blessings and feelings.

"How is this golden hairpin?" Xu Hui turned around, shook her hand, and asked with a smile.

Xu Qilin nodded quickly and said, "It's so exquisite, very good, very good."

Xu Hui put the golden hairpin into a small box, picked up other jewelry, and muttered: "It must not only be exquisite and expensive, but also have good meanings."

Xu Qilin scratched his head and knew that his sister was excited and insisted on taking out many and good things to show her importance to the marriage of her brothers.

At this moment, footsteps sounded outside, followed by the cries of parrots, and another guest came.

Before the palace servant came in to report, His Majesty Li Er walked in.

Xu Qilin hurriedly got up to pay homage, and Xu Hui also stopped and bent her body to salute.

"It's all right!" His Majesty Li Er waved his hand and was a little surprised when he saw Xu Qilin inside. He didn't expect that he would come back so quickly and even ran into the palace.

"Qi Lin is back very quickly." His Majesty Li Er sat casually on the sofa and said, "Come directly to see Chongrong, is there something at home to report?"

Before Xu Qilin could speak, Xu Hui said with a smile: "Your Majesty, it's Qi Qi who wants to get engaged and get married, so he finished the major event in this first month, and then went to work in the King Ji Mansion in Xiangzhou to join the army."

Oh, His Majesty Li Er immediately smiled and said, "This is a great joy. It's a marriage and an official. Two happiness is coming!"

After pausing, His Majesty Li Er asked with a smile: "Which girl is you marrying? What's your family background? How good is your appearance and temperament?"

Xu Qilin spoke and introduced it again, and he had to praise him a few words.

"Little Jade." His Majesty Li Er nodded and said, "It's good, the background is simple. Qi Qi is talented and doesn't have to rely on any tricks."

"Now is a time of great governance. The politics are clear and talented, so we must go the right path." Xu Qilin cleverly complimented.

His Majesty Li Er smiled and thought that Xu Qilin was really speaking. Governing the world is governing the world, and flattering it is a prosperous era, but it is false.

Xu Hui smiled and said, "Your Majesty is sitting for a moment. I am looking for a gift to the bride, and it will be fine soon."

His Majesty Li Er nodded and smiled, "Brothers get married, of course you, a sister, have to care about it."

After pausing, he turned to Xu Qilin and said, "Go back and tell Qi Qi that he should get married and travel far away. After getting married, he will bring his bride into the palace and meet him."

This is an extra grace. The concubines are royal families, so it is impossible to visit relatives. However, if there is an accident at home, you can send eunuchs or palace maids to visit.

The parents and brothers of the concubines, as well as the female relatives of the parents' family, can also visit the palace occasionally, but must be granted permission. If the concubine is pregnant, she can also invite a female relative of the parents' family to come in to serve.

Xu Qilin complained that His Majesty Li Er was too stingy, but Xu Hui had already bowed down and thanked him, "I thanked Your Majesty for your kindness."

His Majesty Li Er stretched out his help and smiled and said, "My beloved concubine is exempt from gifts. By the way, it is okay to choose gifts for the bride, and it is also worthy of the gifts given by the emperor, even if I reward you."

According to the rules, concubines can be from Zhou Ying’s mother’s house, but the gifts given by the emperor are not allowed to be given to others. If they violate them, they will be punished.

Xu Hui thanked again. It is much more convenient to choose now. Don’t worry about this or there.

Xu Qilin thought about it and felt that when the elder brother and sister-in-law entered the palace, it would be better for the elder sister to take out the gift, so she got up and took it away.

His Majesty Li Er raised his hand and pressed it, saying with a smile: "Yizi and Xincheng are going to play at Lizhi Mansion again, and they have also chosen the Lantern Festival. Have you made some new and novel tricks that make them so anxious?"

Xu Qilin didn't dare to say no, nor did he dare to say there was. He smiled and said, "I think someone spread the news about setting off fireworks on New Year's Eve. When His Royal Highness heard this, he had the intention to watch it."

After pausing, he quickly remedyed and said, "If Your Majesty is worried, then the empress will take the fireworks to the palace gate or to the palace of His Highness Changle."

His Majesty Li Er thought for a while and said, "Let's be at the palace gate. I also want to see what the fireworks look like."

"And—" His Majesty Li Er pointed to the corner of the palace and said, "That mirror is small, it is sent to the ten sides of the palace. Now only Xu Chongrong has this place. Others are very jealous and come and go frequently, which makes Chongrong unable to be quiet."

These are gifts given to my sister by others. Do you want a mirror?

Xu Qilin guessed, nodded and agreed, bowed and stepped out.

"This kid did not come up with so many tricks, which made Aizi and Xincheng feel uneasy in the palace." His Majesty Li Er couldn't help but shake his head and smile bitterly when he waited for Xu Qilin to go out, as if he was complaining.

Xu Hui disagreed and smiled and said, "Your Majesty, since Qi Lin and Xiao Zhao frequently enter the palace, have the two princesses become more cheerful and lively?"

His Majesty Li Er had to nod and admit that this was a fact that he saw, and he was actually happy.

Xu Hui stopped talking about it, let’s put aside his thoughts of choosing gifts, sat next to His Majesty Li Er, and said with a smile: “Qi Lin sent all the books printed by Dayingku to me. This book "Natural Common Sense" is very interesting. Have you read it?"

His Majesty Li Er reached out to take it, looked at the cover, and said, "Oh, this is still a textbook. I remember that there is only one mathematics library in Dayingku. Could it be for those students to read it?"

"It should be!" Xu Hui was not sure, and said, "Although this is just some simple and ordinary knowledge, people may not know it. I have learned a lot from it and have benefited a lot."

His Majesty Li Er slightly opened his head and started reading it.
Chapter completed!
