After the whole network was hacked, she traveled through the small fishing village of Datang

With Shenshui hanging in front, Sui Feng worked even harder. It didn't require Su Qingqing to control it at all. It could give the rider the illusion that he was good at riding.

Zheng Tian quickly noticed something fishy. After Su Qingqing ran back again, he stretched out his hand to hold Sui Feng's reins, raised his head and said, "Sui Feng seems to like you Qingqing very much. There are pros and cons to this. Practice. For equestrian, you still need a horse that doesn’t have too many ideas of its own.”

After hearing Zheng Tian's words, Su Qingqing hadn't replied yet. Sui Feng became unhappy at first and raised her head and shook her nose at Zheng Tian.

He didn't dare to raise his foot to kick him, so he directly attacked him physically, and could only use magic to attack.

Zheng Tian seemed to have expected it. While shaking his nose in the wind, he let go of the reins and took a big step back to avoid this wave of biochemical weapons.

"Naughty, do you think I can't do anything to you?" Zheng Tian casually patted Sui Feng twice. Although the action was gentle, it made Sui Feng shiver.

Unpleasant memories came to its mind, so it didn't dare to act like a monster anymore.

Su Qingqing laughed loudly at the interaction between the man and the horse in front of her. After laughing, she held Zheng Tian's hand and jumped off Sui Feng's horse.

"Brother Taiwen is right. When learning equestrian, you have to practice your skills conscientiously. You can't take shortcuts. Sui Feng is too smart and is really inappropriate."

This is just like a bad friend who helps you with your homework. No matter how beautifully he helps you write your homework, once the other person is away, you have to reveal your true colors.

Su Qingqing replaced Zheng Tian's new horse, which made Sui Feng so angry that he kept digging at the ground, making a "clang" sound with his iron hooves.

Zheng Tian noticed the iron pieces on its feet and asked curiously: "What is this?"

Su Qingqing glanced at it and replied casually: "Horseshoes."

"Horseshoes?" Zheng Tian squatted down and raised Sui Feng's horseshoe with one hand to study it, his expression thoughtful.

Su Qingqing drew a sketch, then asked Chen Lizheng to issue a certificate, and then went to Mr. Wang Qi to endorse it. Finally, Su Qingqing took it to the blacksmith shop to find a blacksmith to type it out.

In order to nail this horseshoe to Suifeng, after getting the horseshoe from the blacksmith shop, the village carpenter Chen Tiezhu and the village chief's son Tian Youmi, under Su Qingqing's dictation, tried several times before they succeeded, and they almost got hurt. Sui Feng's kick.

Su Qingqing is basically the king of words. It is all about theory and decomposition diagrams from a modern perspective. The actual operation still requires the help of the native people of the Tang Dynasty.

In fact, horseshoes appeared sporadically on war horses in the late Tang Dynasty, but the mainstream army of the imperial court did not have this equipment.

Zhao Rushi of the Song Dynasty recorded in his "Zhufan Zhi" that horses in the Dashi Kingdom "used iron as shoes". The term was very novel, which proved that in his understanding, horseshoes were not popular in the Song Dynasty.

It is generally believed that horseshoes were widely used in the army among the Mongolian cavalry in the Yuan Dynasty.

But this does not mean that no one in China had thought of this matter before the Yuan Dynasty.

Because in the Goguryeo ruins in the three northeastern provinces in the north, archaeological evidence has discovered physical materials that were clearly horseshoes, and they were from the third century AD.

Among the murals of the Mogao Grottoes in Dunhuang, there is also a picture of "nailing horseshoes", which is on the wall of Cave 4 built in the 302th year of Emperor Kaihuang's reign in the Sui Dynasty.

The above archaeological discoveries are enough to prove that horseshoes appeared in China before the Sui Dynasty.

But it was indeed not popular in the late Tang Dynasty. Even a well-read scholar like Zheng Tian had never seen it and expressed curiosity about it.

After looking at the horseshoe, Zheng Tian stood up and asked Su Qingqing: "What is the magical use of this thing?"

Su Qingqing thought for a moment, organized her words and said: "After shoeing a horse, the shoe will not crack no matter how much it runs." Zheng Tian did not answer immediately, stood silently for a moment, and suddenly gave Su Qingqing a long shot. A gift: "This is a wonderful thing. It can save a huge amount of military expenses every year. Please accept Zheng's gift."

Su Qingqing quickly dismounted and returned the favor: "What are you doing, Mr. Zheng? It's just that I put on two pairs of iron shoes for Sui Feng in private. It's just a strange skill."

Zheng Tian put his hands behind his hands and smiled, his eyes full of admiration and appreciation: "But these two pairs of iron shoes can save one hundred thousand military expenses."

Su Qingqing turned her head and looked at Zheng Tian and said, "But Mr. Zheng has no official position now, so he still cares about these things?"

"I'm not in the court, but my heart is still with it. If Qingqing agrees, I want to tell my father, and my father will write to the court about the wonders of this thing." When he said this, Zheng Tian had a calm face, obviously not because of the current moment. Feeling disappointed at the low point.

He seems to have thousands of ambitions in his heart, pretending to be about his family, country and the world.

Yes, he is the person who saved the building from collapse in history.

It's a pity that Zheng Tian was too loyal and upright, defeated the Huangchao rebels, recaptured Chang'an, and brought the Li Tang Dynasty back to life. His achievements were not rewarded, but were ostracized by villains.

As soon as the extremely decadent central court regained its breath, Tian Lingzi, Gao Pian and others, who had been beaten to pieces by Huang Chao, joined forces to take down Zheng Tian.

Maybe this is what a gentleman can bully?
Villains have no choice but to submit to immoral people, but for virtuous gentlemen, they can suppress them with the power of imperial power and fake tiger power.

Although the last savior of the Tang Dynasty was exiled by the faint king who had no clear idea of ​​rewards and punishments, and failed to save Li Tang's life, he was still able to survive and was not destroyed immediately.

Just, is it worth it?
Su Qingqing's eyes became complicated when she thought about the contents of Zheng Tian's biography.

Zheng Tian felt Su Qingqing's sudden sympathy and couldn't help but laugh: "What's wrong? Does Qingqing feel sorry for someone who has no official position now?"

Su Qingqing shook her head: "No, it's just...well, I can't tell. As for the horseshoes, it's up to you, but don't mention me. In fact, I didn't think of this thing myself. It was my brother who traveled around and saw it and told me about it. Yes. In the north and west, many barbarians have been equipped with horseshoes."

"Oh, is that so?"

"Hey, let's not talk about this anymore. Brother Taiwen, please continue to teach me how to ride a horse!"

Zheng Tian smiled casually: "Okay."

In the days that followed while waiting for the corncob wine to ferment, Su Qingqing would learn singing and dancing behind closed doors in the morning as usual, and open the door in the afternoon to make it easier for neighbors to come in and visit.

Zheng Tian usually came over in the afternoon to teach her how to ride a horse.

The two of them moved from the rugged mountain road at the beginning to a valley.

The place is between Chenjiacun and the small fishing village. The entrance is narrow and was previously blocked by huge rocks.Zheng Tian discovered it while standing on the top of the mountain while inspecting the terrain near the small fishing village.

After using gunpowder to blast away the boulders blocking the passage, there will be a large valley plain inside, which is very suitable for horse racing.

Gunpowder was nothing new in the Tang Dynasty. Taoist priests often used it to make elixirs. Fireworks were also a must-have item on New Year's Eve and important days.

Sun Simiao, the king of medicine, even summarized a gunpowder recipe specially used to make elixirs. This can also be regarded as the earliest gunpowder formula in China.
