Surrounded by warblers and swallows, the fragrance of fat powder is lingering, Xu Qilin is a little dazzled, and the big pig's trotters can't help but grope and explore.

"Xu Lang knows that Yiyi is the number one brand in Yichun Courtyard, and if she leaves, her business will definitely be affected." The fake mother looked sad, pointed to the Yingyan in the house, and said: "If the business is not good, these children will starve and suffer, how pitiful." ”

Xu Qilin said: "It's not so miserable. Let's just say that these sisters in the house, in terms of appearance and talent, are no worse than Tang Niangzi! ”

"Having said that, how can the reputation be all at once?" The false mother wiped her nose with a handkerchief, as if she could shed tears.

"Let's just talk about Meimei, the slave family is optimistic about her, but there is no chance to be famous." The fake mother pulled a girl, who was indeed very beautiful and had a bit of a fresh taste.

Mei Mei, mildew, no ...... Before Xu Qilin could figure out the words, Meimei had already posted it. probably felt that Xu Qilin was young, but she shook off her shyness, and her actions and words were extraordinarily affectionate.

"In a few days, it will be Yuan Xi, Xu Lang doesn't write poems for the slave family, thinking that he needs to be famous?" Meimei hugged Xu Qilin's arm, shook it gently, and breathed on her lips, close to her face.

Xu Qilin's heart was shaken, but there was still a trace of clarity, and he looked at the fake mother and said: "It's not impossible to write poems and fill in the lyrics." But does this have anything to do with Tang Niangzi's redemption? ”

The fake mother hesitated for a moment, thinking that she could compromise.

A good poem can win the red rose, and Tang Yiyi is gone to make up for it. Moreover, judging from Xu Qilin's future, it is not easy to offend.

Now it's good to talk and discuss, and it's better to get off the donkey down the slope to his satisfaction. What's more, even if the ransom silver doesn't open her mouth, it can still make her a fortune.

"If Xu Lang gives a good poem, the slave family will show his gratitude, and he will allow him to redeem himself according to his conscience." The fake mother said with a smiling face: "Meimei, I haven't thanked Xu Lang yet." ”

"The slave family thanked Xu Lang." Mei Mei hugged her tighter and kissed Xu Qilin on the face.

Xu Qilin smiled, turned his face and kissed him. This can't be a loss, you kiss me, I kiss you, it's fair!

However, he was still a little uneasy, and said: "In this way, let's just do things, don't drag the mud and water." Now I will call Tang Niangzi here, and I will do a good job of redeeming myself, and a certain poem will be done. ”

The fake mother clapped her hands and said with a smile: "What Xu Lang says, what the slave family will do." With that, she got up and walked out, and went to discuss the redemption with Tang Yiyi.

Not in the face of Xu Qilin, the amount of this ransom silver is naturally easy to discuss. The fake mother didn't want Xu Qilin to talk about Xiang on the side, which made her difficult to bargain.

"Xu Lang is full of talent, and this place is full of poetry and songs!" Meimei was courteous, reached out to touch Xu Qilin's belly, and moved it down gently.

Xu Qilin hurriedly pressed the girl's hand, don't touch it, Lao Tzu will not be able to stand it.

Meimei giggled and teased: "Xu Lang is afraid, are you afraid that the slave family will eat you?" ”

Xu Qilin sneered and asked a young lady to tease, how did this seem to be reversed. Shouldn't I be here to tease my sister?

There was not much time, the fake mother and Tang Yiyi walked in, there seemed to be tears on their faces, and they didn't know whether they were really reluctant to separate, or acting hypocritically.

"The slave family thanked Xu Lang." Tang Yiyi bowed down.

Xu Qilin helped him and asked, "Is the matter done?" ”

"That's it." Tang Yiyi replied: "The deed can be written immediately." ”

The fake mother laughed with her and said, "Xu Lang opened his mouth and gave the slave family 10,000 guts, but he didn't dare to bully each other." ”

"Thank you for this." Xu Qilin arched his hand and said: "This poem is also thought of, prepare the pen, ink, paper and inkstone." ”

The fake mother hurriedly asked people to prepare, and Meimei had eyes, and personally stepped forward to lay paper and polish ink.

"Since it is sung on the eve of the new year, it must be in accordance with the time." Xu Qilin got up and picked up the pen, pretended to think for a while, dipped himself in ink, wrote with a wave, and did it in one go.

On New Year's Eve last year, the flower market was lit up like day. The willow tops on the moon, people about after dusk. On New Year's Eve this year, the moon and lights are still the same. I didn't see last year's people, and I was full of tears.

Meimei chanted in a low voice, her eyes lit up. When Xu Qilin finished writing, he immediately bowed down and thanked him, "Thank you Xu Lang for the poem." ”

Xu Qilin smiled, put down the pen, looked at it, whether it was words or poems, he felt satisfied.

When the false mother saw Meimei thanking her, she knew that this poem was good, so she put her mind at ease.

At this time, the deed had already been written and sent in. The fake mother and Tang Yiyi drew a bet, which can be regarded as the end of the transaction.

Watching the fake mother squeeze tears again, Xu Qilin admired in his heart, this acting skill is worthy of a little golden man. When the matter was done, he did not stay long, but got up and wanted to leave.

Tang Yiyi got the deed of sale and couldn't wait to leave here. only took a small burden, and followed Xu Qilin out of Yichun Courtyard.

Although Yichun Courtyard is not a prison, Tang Yiyi can also go out. But at this time, when I saw the world outside, I was in a very different mood. It's as if the bird has left its cage and is free to fly at will.

With a long breath, as if the air outside was also fresh and comfortable, Tang Yiyi's eyes were red, and she almost burst into tears.

Xu Qilin glanced at Tang Yiyi, happy for her, and understood her feelings.

After a pause, Xu Qilin said, "Does Tang Niangzi have a place to go?" If you don't have it for the time being, you can go to live with Mrs. Zheng first, and it's not too late to look for it slowly. ”

Tang Yiyi lowered her head slightly and said, "The slave family wants to settle down in the opera troupe, but I'm afraid that Mrs. Zheng doesn't want to." ”

"Let's go and ask." Xu Qilin smiled, stretched out his hand and made a gesture of invitation to the carriage, "There is still something for Tang Niangzi to help, let's talk about it in the car." ”

Although the social status of the drama is not high, it is a free body, and there is no need to sell his body and pretend to laugh. Compared with advocacy, it is still the profession that Tang Yiyi hopes to engage in.

What else can I do? The ransom silver was almost what she had accumulated for many years, and now there was not much left, and there was not even a place to stay.

………………

In the afternoon of the next day, the people sent by Xu Qilin to the weapons prison came back and successfully borrowed three catapults.

It is not only the role of His Majesty's edict, but the people in the weapons supervisor also know that Xu Qilin will definitely be able to ask for an edict. After making an excuse to delay yesterday, I immediately gathered the craftsmen and rushed to work overnight, and it was finally completed.

When Xu Qilin saw the brand-new wood of the catapult, he immediately understood. His Majesty Li Er's judgment was right, and he deliberately left some time, which was also correct.

In the wars recorded in Chinese history, trebuchets were used very early. For example, the thunderbolt cars of the Three Kingdoms, and the current "cannon".

That's right, trebuchets were also called "cannons" in ancient China. You can guess by looking at the words that it has something to do with stones. Later, with artillery, the stone word was changed to the fire word side.

Although trebuchets have evolved over the centuries, little has changed. After the actual operation, Xu Qilin felt very disappointed.

At that time, trebuchets were divided into three types: light, medium, and heavy:

Light throwing car, cast by two people, the stone bullet weighs half a catty, up to about 100 steps;

Medium-sized throwing cars have single tip, double tip, whirlwind, tiger squat, etc., which require 40 to 100 people to pull the cannon cable, and can fire 25 pounds of stone projectiles, with a range of 130 steps;

The heavy throwing cart has five and seven cannons, operated by 150 to 250 people, and can fire 70 to 100 pounds of stone bullets, with a range of up to 80 steps.

According to the ancient unit of length, one step was about 1.3 meters, and 130 steps were 169 meters. The 100 steps and 80 steps are 130 meters and 100 meters respectively.

See, the trebuchet, which was regarded by Xu Qilin as an old and powerful heavy weapon, was at that level at that time, even lower than the range of a bow and arrow.

The trebuchet made by the weapons supervisor is three double-tip cannons, each of which requires at least fifty people to pull the ropes, and after just one demonstration, Xu Qilin couldn't stand it and shook his head.

In addition to the siege, this trebuchet is really a chicken rib existence. Even if it is a siege, at this distance, it will face a condescending attack from the enemy on the city wall.

No wonder the weapons supervisor didn't pay attention to it, and the trebuchets didn't have troops! It's bulky and not easy to use, and it's very powerful.

Xu Qilin circled around the trebuchet several times, and his thoughts gradually opened up.

In fact, in addition to tunnel blasting, there is actually a relatively simple way to siege the city, that is, to create a more powerful trebuchet, or called "return cannon" and "Xiangyang cannon".

Although the power of tunnel blasting is great, it also has its limitations. For example, moats, soil quality, etc., do not guarantee that every city will be suitable.

The "return cannon" is different, it can be bombarded when it is built. Even if you throw stones, the weight of a few hundred catties is enough to smash down a city tower.

Moreover, the firing range of the giant "return cannon" can reach more than 300 meters, which is completely outside the attack range of the enemy at the head of the city, and it is very safe.

In other words, with the "return cannon", it was a devastating blow to the rammed earth city wall at that time. Although the shortcomings of bulkiness and slow launch cannot be corrected, the speed of siege is still not surpassed by other methods.

One step ahead is a genius, two steps ahead is a madman. Xu Qilin felt that he was a genius by improving the trebuchet into a "return cannon"; It would be a bit crazy to think that a real cannon could be made in a short period of time.

Even if it is a "return cannon" with the same principle, it is a technology that is hundreds of years ahead. The Mongols relied on it to attack the city and destroy the Southern Song Dynasty.

Thinking of this, Xu Qilin calculated the time, and felt that if the craftsmen were concentrated, they would be able to build a "return cannon" in five or six days. It doesn't have to be extra-jumbo, it is enough to throw a medium-sized one of about 200 meters.

Just do it, Xu Qilin sent someone to the weapons superintendent to ask for the drawings of the trebuchet and recruited craftsmen. He studied the drawings, calculated the data, and began to improve.

The principle of the "return cannon" and the trebuchet is the same, and the shape is also similar, both use the principle of lever.

So, it's not that complicated to improve. As long as the size is enlarged, and then the other end is designed as a counterweight, plus a few winches with the principle of axles, it is basically the same.

Again, many scientific and technological inventions are not limited by the level of technology, but by the innovation of ideas. The change of the human-pulled trebuchet to the counterweight type did not involve any technological revolution at all.

After arranging the work, Xu Qilin hurried to the auction to watch the auction results of the mirror.

When he arrived at the theater, which was temporarily used as the auction venue, there were already several rows of people who had come to participate in the auction.

In order to prevent people from mixing in, those who can enter the venue are registered in advance, and license plates and instructions are issued to familiarize them with the rules.

Xu Qilin stepped up to the second floor, sat in the box, and gestured to the staff on the stage to signal the auction to begin.

With the melodious music, the noise in the venue gradually subsided, and Tang Yiyi, who was dressed up, walked onto the stage and bowed to the people below.

The music stopped, and Tang Yiyi's clear voice echoed in the theater.

"The items in today's auction are made by Da Yingku, a total of fifteen exquisite mirrors and five vanity mirrors."

Tang Yiyi stretched out his hand to signal, and the staff next to him uncovered the silk cloth, revealing the mirrors arranged on the table, reflecting the sunlight, and the eyes of everyone below also lit up.

Waited a moment so that everyone could see it clearly, and brew the mood, and also know the number of auctions today.

Tang Yiyi waved with a thousand manners, and the staff walked up with a small mirror, looked at the various positions of the people below, and finally put it on the table next to Tang Yiyi.

"This is the first lot in this auction, Linglong Mirror No. 1." Tang Yiyi said with a smile: "That's right, the serial number behind the mirror is not only an anti-counterfeiting, but also a mark for a limited edition." ”

No. 1, whoever shoots it has a lot of face! Xu Qilin sipped the tea lightly, with a wicked smile on his face.

"The bottom price of this mirror is 100 yuan, and the price increase shall not be less than 10 yuan each time." Tang Yiyi elegantly stretched out her arm, slowly unfolded it underneath, and said, "Now, the auction begins." ”

"One hundred and twenty!"

As soon as Tang Yiyi's voice fell, someone raised a sign to offer.

"One hundred and fifty times!"

"One hundred and eighty times!"

"Two hundred!"

The interval between the quotations is so short, fortunately, Tang Yiyi passed through Xu Qilin's guidance, and when she encountered this kind of situation that made her too late to repeat and explain the number of signs, she didn't have to worry, just stretched out her hand with a smile.

The quotation continued, perhaps stimulated by the limited edition and the first number, and the degree of enthusiasm was stronger than Xu Qilin expected.

When it came to the price of 300 guan, there were fewer quotations on the cards, and the frequency slowed down. After all, if he is a businessman, he has to consider the space for resale, and he will not be too competitive because of what is the first and second number.

"Thirty-six, three hundred and twenty." Tang Yiyi finally had time to speak.

"Sixty-four, three hundred and thirty." If he only raised the card and didn't speak, Tang Yiyi added it according to the lowest ten.

Four hundred and twenty times, no one seems to raise a card anymore.

Tang Yiyi smiled and said, "Four hundred and twenty times, is there any price increase?" ”

After glancing around, she raised her gavel and said in a low voice: "Four hundred and twenty times, once; four hundred and twenty times, twice; Four hundred and twenty times, three times. ”

With a snap, the gavel was struck, Tang Yiyi stretched out his hand and said loudly: "Congratulations to the No. 64 guest, who took the Linglong Mirror No. 1 with 420 strokes." ”

Everyone turned their heads to look at No. 64, but they didn't know each other, thinking that they were afraid of publicity, and sent a little person.
