The architecture of the bike is extremely simple, with two wheels, a single frame, a chain, two gears, and a pair of pedals.

The wheels can be made of pure iron or pure wood, and there is no such thing as 'oil', and there is no such black rubber, but Liu Xuan believes that there must be a lot of oil buried in the ground of this world.

When the Ministry of Industry sent the first bicycle, Liu Xuan's eyes were full of bright colors, and he finally saw a modern means of transportation close to the people's livelihood.

It is simple to make, low cost, convenient transportation and environmentally friendly.

If this continues, his country can rely on bicycle sales to fill its coffers to meet the world's highest 'duty-free' standards."

In front of the door of the Taihe Palace, all the officials gathered, looking at this strange bicycle with two wheels, the wheels are made of pure wood, wrapped in a circle of iron sheets, and there are gears and iron bars fixed in the middle, I really can't imagine how the two wheels move.

But when they saw Liu Xuan stepping on the bicycle and leisurely walking in the square in front of him, everyone's eyes widened in shock, and they were not stunned by such a magical scene.

From the front of the Taihe Hall to the gate hundreds of meters away, it takes about ten minutes to walk, and with a bicycle, it can be reached in less than a minute.

"Ji Aiqing, you can try." Back in front of the hall, Liu Xuan got off the bike, turned his gaze to Ji Fang and said with a smile.

Ji Fang was stunned, bowed slightly, and walked to the car, Liu Xuan looked at him with a light smile on the side, looking like he didn't care about himself, and said, "With Ji Aiqing's talent, this little bicycle should be able to look at it." ”

"The emperor has won the award, and it is the first time for Weichen to see such a strange car, I don't know if he can be as flexible as the emperor." Ji Fang replied very modestly, and after speaking, he stepped on the bicycle in style, stepped on the pedal with one foot, and swayed, and it didn't take long for him to ride up.

Liu Xuan looked at him in surprise, to say that this bicycle also needs technical content, I think back then, it took him several days to learn to drive for the first time.

Ji Fang rode the car, with excitement on his face, and he even thought about what kind of prosperous scene the future of the entire Nine Shadows would be if this car was promoted.

The other officials were eager to try, and Liu Xuan didn't stop them, letting them try them one by one, and the whole square was full of laughter.

At that moment, Liu Xuan ordered the Ministry of Industry to build a car factory, and each official gave a bicycle, and when there were more cars, they could be sold or even exported to other countries.

This suggestion was naturally strongly endorsed by hundreds of officials, and the Ministry of Industry was naturally the most proud, anyone can imagine how profitable the bicycle would be if it was carried forward.

Now Jiuyou is thriving, the officials are loyal and dutiful, the people are back, and Liu Xuan is rarely idle.

Conquered the Great Luo River, so that everyone in the entire Jiuyou revered the emperor.

But the only thing that made Liu Xuan depressed was the four concubines in the harem.

And the most dissatisfied is the queen Li Yuelian.

Originally, the emperor had been on an expedition for three years, and now it was the happiest thing for her to return to the court in triumph, but when she saw Liu Xuan come back with a Da Luo princess, her face was not good at the moment, and she didn't speak for half a month.

And Ji Fang brought a fourth concubine from Dayin-Zhu Xinxin, and her first impression of Liu Xuan was that she was a little beauty of the small family jasper, eighteen years old, with a sweet and quiet appearance.

Li Yuelian was furious at that time, glared at Ji Fang for a long time, and Ji Fang only didn't squint, smiled respectfully, how many concubines does this emperor have.

Li Yuelian didn't seem to want to let Ji Fang go, and the next day she summoned Ji Fang and asked him to stand outside the Rejuvenation Hall for a day, and let Ji Fangbai wait for a day, Ji Fang recognized it, and stood for a full day, and when this matter reached Liu Xuan's ears, he was also silent with a smile.

And the second concubine Wu Qingyue seemed to be a lot quieter, Wu Qingyue, who has always been gentle, heard that Liu Xuan had gone out for three years and brought back two concubines, and she couldn't help but feel jealous in her heart, but according to inertial thinking, which emperor didn't have many concubines, the emperor brought two concubines now, but he added two concubines, and there was nothing, nothing to be surprised and jealous of, because this is a very normal thing.

But the sourness in her heart is indescribable, at that moment, she even supported the queen Li Yuelian very much, or she was a little envious of her bravery, and any dissatisfaction would be written on her face, which made people understand it at a glance.

And the most surprising thing is Nangong Yi, she knows that as an emperor, it is normal to have many concubines, and even has accepted such a law, but she didn't expect that Liu Xuan has only four concubines including her now, which has an incredible feeling in her concept, her younger brother Nangong Mu has hundreds of beauties in the harem, why is Liu Xuan only four?

And after staying in the Jiuyou Palace, she found that the rights of the concubines are extremely powerful, except for the emperor, no one can control them, you know, the most terrible thing in the harem is the palace fight, but in Liu Xuan's palace, the palace fight between the concubines can be, it is all on the bright side, if any concubine wants to punish another concubine, okay, do it yourself, want to fight, okay, do it yourself, those eunuchs under their subordinates, even if the concubine makes a big mistake, it is not their turn to do it, even if it is the master's order.

This made Nangong Yi breathe a sigh of relief, she came to the harem and wanted to keep a low profile, but after being familiar with it for a while, she didn't need it, no one cared about where she wanted to go, and even when Liu Xuan was in the court, she could sit in the back hall and wait with a swagger.

And Nangong Yi can also do some kung fu, once he talked back to the queen, the two stared at each other, and the female eunuchs of the palace on the side were prostrate on the ground, where did they dare to interfere, so Li Yuelian also knew how to do some kung fu, the two almost fought like this, fortunately, Wu Qingyue on the side came forward to stop it, and Zhu Xinxin on the side was frightened and silent, looking extremely well-behaved and obedient.

Speaking of Wu Qingyue, I have to mention her daughter, the little princess of Jiuyou-Liu Wei.

Liu Xuan is more than two years old, and the first thing Liu Xuan did when he came back was to run to Qingyue Palace, and when he saw his good daughter who could already walk on the ground, Liu Xuan's state of mind at that moment seemed to return to the beginning.

He even thought that if he lived here peacefully and happily like this, managing the Nine Shadows, it seemed to be an extremely enjoyable thing to live this life with peace of mind.

However, the good times did not last long, in the seventh year of Xuande, farther north, the Great Mongolian Empire came to marry the envoy, and at the same time, half of the Northern Yin Empire had been annexed by the Great Mongolian State
