With a small "duang", the first slab rests securely on the deck, perfectly assembled with the piers and the slabs next to it. The placement of the second bridge plate has been much faster...... At the moment when the birds return to each other, the Langao Bridge can be officially opened to traffic!

Li Yuanying took the Jinyang small bun and the black pheasant with the belly, riding their respective Datang bicycles, and marched towards the other side of the river... Xiao Baozi's physical strength is good, and the bridge with a total length of 700 meters and a main span of 300 meters reached the opposite bank in less than a quarter of an hour, and he rode back to the same place very excitedly.

Yuan Tiangang looked at the sky speechlessly, knowing why he had a cold back, now this pedal car is still manpower, if it is replaced with the oil engine studied by Du Che, if the guards in Chang'an do not ride horses and change to a two-wheeled oil engine...... Except for those of us who use flying swords or talismans to communicate with each other, which thief has run past Jin Wuwei? And Yunhe Mansion is in Furong Garden, which person who travels with a flying sword or a talisman dares to make trouble in Chang'an? No one dares to make trouble! The curfew in the eastern and western cities of Chang'an can be gradually lifted, and the walls of each square will be reduced to nothing, and gradually be torn down, like the newly built western city.

Teng Wang ...... Everything has nothing to do with King Teng. The oil engine was designed by Du Shilang, the drawings of Xicheng were drawn by Wei Sanlang and Yan Liben, and the pedal car was made by Shaofu according to the toys of the wooden galloping horse, and the wooden galloping horse was only carved by King Teng in order to let Princess Jinyang exercise indoors, and he had nothing to do with the subsequent development and half money!

Why is it this cyclical process every time? A certain discovery is indeed in Chang'an, but it is not an emergency that makes a certain robbery, nor is it an alien object, but the vertical son of King Teng!

Something is wrong, something is really wrong, after talking to His Majesty at that time, someone should leave Chang'an immediately, instead of helping King Teng make fireworks and telescopes, as long as he doesn't do those two things, he won't make a steam engine, and if he doesn't make a steam engine, he won't invite Gongsun Old Ghost, and he won't invite Gongsun Old Ghost...... No, I shouldn't have seen Wei Heihou, and I shouldn't have seen King Teng playing the white stacked ball...... It's not right, so-and-so shouldn't be fireworks!

Why would it be a person in a certain catastrophe? I'd rather cut off the dragon vein...... Why should you be greedy? What do you want to see a group of dragons on pilgrimage! Something is wrong, something is really wrong...... Can you go back to before Yuanzheng?

Li Yuanying handed the wooden version of the bicycle to Chun Tao, looked at Yuan Tiangang suspiciously, and asked, "Yuan Gong." Isn't it raining tonight? ”

It's not in Ninghui Pavilion, there is no new armillary sphere, what can you see if you look at the sky for so long?

Yuan Tiangang looked at Li Yuanying with resentment in his eyes, and he was so frightened that he hurriedly took five or six steps back......

…… Li Yuanying swallowed nervously, covered his chest with his hands, and said in a low voice: "I haven't abandoned your apprentice from the beginning to the end, let alone done anything to dig a fire well or watch the Jiashan Mountain!" ”

Yuan Tiangang and Li Chunfeng both chose Guanjia Mountain as their place to bury, and it is obvious that Yuan Tiangang is one step higher, and his position happens to be impartially located in the throat of the ancient soldiers, that is, in the later generations, so he has never been alarmed...... It is commonly known as not being patronized by the captain of the touching gold.

Yuan Tiangang: "......"

I guessed correctly, it was really him! Wait a minute...... looked at Li Yuanying suspiciously, and asked, "How do you know about Guanjia Mountain?" ”

"Brother Chunfeng said." Li Yuanying directly threw the pot to the stargazing people in Chang'an, anyway, he was drunk more than once, and he didn't say it, and he couldn't remember it so clearly, not to mention that he really said it. He took three more steps back before he whispered, "The golden needle pierces the eye of money." ”

Li Chunfeng said that back then, he and Yuan Tiangang each had to choose a piece of feng shui treasure land for themselves, and it was also a test of his physiognomy. They left Chang'an one after the other with a compass, all the way south to search, first came to Langzhong Yuan Tiangang saw Guanjia Mountain, thought it was a treasure land with excellent feng shui, and buried a copper coin as a mark. Soon after, Li Chunfeng also came to Langzhong, and on the way to find it, he also fell in love with the feng shui where Guanjia Mountain was located, so he inserted a golden needle as a mark. Later, when the two met, they both said that they had chosen an excellent feng shui treasure as their home, and as a result, they found that they had picked the same place, and the master and apprentice who could not argue dug up the marks they had made before, and they were surprised to find that Li Chunfeng's golden needle was just inserted in Yuan Tiangang's copper coin eye. So they retreated five miles and set their place for refuge.

It is not much different from the legends of later generations. A deep suspicion was that the two of them deliberately created momentum for themselves, so that the elder brother would believe that Li Chunfeng's ability was not under Yuan Tiangang, and lay the groundwork for Yuan Tiangang to go away.

Yuan Tiangang rolled his eyes, pointed to the chair next to him, and said, "I just thought of a plan to improve the pedal bike, and I feel a little ...... Tired. ”

The use of the oil engine in the steam car or steam car does need to be studied for a long time, the continuous stability and the addition of the oil oil, as well as the calculation of the carrying capacity...... Without a year or two of experiments, it is impossible to apply it to long-distance transportation. It can only be used in Chang'an without any problems, and it can even be designed to load a two-person car with better stability.

After listening to Yuan Tiangang's narration, Li Yuanying stared at the peerless master of the fairy wind in front of him with round eyes...... That's how you came up with motorcycles? A certain traverser is very undistant! Are you ancients devils? If more than ten years later, Xiao Baozi took a group of noble girls and Xiao Langjun to ride a motorcycle and ride a brick on Suzaku Street...... There was a little bit of a horror in that scene! Will Brother take care of it? Of course not. Will the pheasant slave care? Of course not. Will someone care? At that time, it was either in Suzhou or Hongzhou, and my hands were not that long, so I couldn't manage it if I wanted to. Will a certain refuse to list motorcycles? What are you kidding, it's all small money! He coughed lightly twice and said, "Three or five years...... Or after two or three years, it can also be used for wine and food delivery, and those who like to go to Leyouyuan or Qujiang Pond to enjoy the scenery will like it very much. ”

Yuan Tiangang frowned slightly, and he could also give away other things if he sent wine and food, and said thoughtfully: "In that case, the oil machine needs to make some small objects on the oil machine to limit their riding speed, so that no one can use it to do evil." ”

"Hahaha......" Li Yuanying leaned back on the chair and laughed. Yuan Gong, don't you really think that those splashes completely rely on their own strength to do anything wrong in Chang'an, and the county officials of Wannian and Chang'an have nothing to do with them, right? ”

Because of the gray san incident, the ancients played more tricks. The traffic conditions of the Tiangao Emperor Yuan, coupled with the literacy rate of Wen Mang is the norm, the difficulty of the S side is not weaker than the difficulty of the Shu Road, so they are not popular with the S side, and a limited number of people on the S side have basically obtained the opportunity to go down in history.

For example, Chun Yu Tiying, who was punished on behalf of his father and was willing to be a palace maid, such as Yang Yaozu, who had been fighting for land for nearly 300 years, such as Feng Liangchun, who was worried about having no rice to cook, and Yang Juzhen, who rolled the nail board for his younger brother...... They have no illiterate people who don't speak, and they are not ordinary people. Most of the people who sue the royal complainant still appeared in the braid period, true and false, false and true, uh, uh, it's hard to say, after all, they play more words and hell.

"There is Yunhe Mansion and a certain demon king, before they want to do anything, it is best to weigh their backstage, whether it is stronger than Fang Xuanling or Qinghe Cui Clan and Boling Cui Clan."

Fang Renyu, Choi Yizhi, Choi Yixuan, and Choi Renshi...... In the eyes of outsiders, is there some deliberate targeting of the Qinghe scholars? The main reason is that they like to hit the muzzle of so-and-so, and so-and-so can't always condone them to spread wild on so-and-so for a few rumors.

Li Jing and Tang Jian, who had just walked by: "......"

Fang Xuanling heard this...... Definitely crying, sorry for the wrongs. However, the people who were cleaned up by King Teng seem to be Qinghe or Shandong families, because the injured head of the Zheng family in Xingyang will be counted on the head of Yunhe Mansion, which is equivalent to being his pot in disguise, and he needs to change his attention in a different direction.

"When Lao Cheng comes back, he will reorganize the corners of Chang'an." Li Jing sat on the chair beside Li Yuanying and said softly. "Jin Wuwei's axe guards can reach half of them at present, and the scene of shooting is very extraordinary."

It is slightly worse than the salvo of ten thousand arrows, and in Chang'an, except for the period of the great melee at the end of the dynasty, it is impossible to see the scene of ten thousand arrows firing at once.

"If the Baqiao is built like this, those friends of Fanbang will bow and worship at the bridge." Tang Jian looked at the sunset on the horizon and said leisurely. To deter outsiders, there is not only one trick of iron horseman, of course, the most deterrent effect is definitely iron horseman...... Now to add artillery.

Li Yuanying told Yuan Tiangang's thoughts on the Tang version of the motorcycle in detail, and added some of his own opinions, asking: "What do Tang Fu and Yao Shigong think?" ”

Li Jing blinked, using fire oil to provide power, and the speed can be doubled? That...... What will horses do with in the future, pets? The reason for the inappropriate ingredients is very simple, horse meat is not only delicious, but if eaten with ginger, it will cause a cough, and if it is eaten with pork, it will become cholera. No one will eat horse meat unless they are hungry and have no choice...... Of course, there is a more important point, how can there be a war without horses? As long as there is the slightest possibility, not only can you not eat them, but you must feed them.

"Double the speed?" Tang Jian sat up straight, his eyes looked straight at Yuan Tiangang, his face was very solemn, and he said solemnly: "Yuan Gong, are you sure that it is doubled?" This is no joke! ”

Normally, His Majesty is very generous, and there is no bad habit of dragging it out and cutting it at every turn, but ...... It doesn't mean that he can endure the deception of others, although Yuan Gong has always been reliable, but the statement that the speed has doubled, no matter how it sounds, it sounds like drawing a cake out of thin air, hoping to quench Mei's thirst.

"It is only necessary to solve the problem of the wheels, and the speed is just a conservative value." Du Che walked over with the freshly picked raspberries and wild plums and said softly. "The solid structure of the wheels of the steam car is too wasteful, not to mention the eucommia, and there are also restrictions on speed. We have also tried the inflatable structure, and the wheels are prone to overheating and exploding at high speeds. ”

Friction heat generation is a natural law, and we can only find ways to reduce it, and there is no way to completely avoid it...... Even if it does not touch the ground, the process of driving at high speed will drive the air, creating an airflow similar to the wind, which will also cause friction.

"Have you ever tried the yang energy extracted by Liu Erlang?" Li Yuanying touched his chin and asked softly. Most of the yang gas is inert gases such as carbon dioxide and nitrogen, and nitrogen is the majority. Later generations of tires are inflated with nitrogen, and the history of being used in aviation and aviation, junshi, and racing cars is only about 20 years, which can reduce punctures, reduce driving noise, prolong the service life of tires, and the most critical point is to reduce fuel consumption. Eagle sauce kept issuing hats for the sake of oil in the place where the big dog families lived, and after decades of calling, he calculated the accounts and found that the profits were far lower than the overdue, and began to issue hats to the flower growers.

Energy issues, manipulated by countries such as Eagle Sauce, John Bull, Long-legged Chicken and Hans Cat, have become even more scarce. However, they are not monolithic, when Da Mao and Er Mao set off fireworks indiscriminately, Eagle Sauce cut a few stubbles of tender leeks from old friends, and Tian Mou was like a mad cow at a price, running all the way up. John Cow, Long-legged Chicken and Hans Cat are in pain and "happy", after all, the fat water does not flow into the fields of outsiders~

It's just that the name of yang is too weird, and you should get the microscope as soon as possible.

"Huh?" Du Che didn't sit down, he turned around and left directly, saying as he walked. "Lord Wang, I'm going to do experiments with Sun Gong and the second senior brother!"

Why did we never think about using yang energy? Teng Wang's expertise is not as good as ours, but his whimsy can often help us open new windows, and then we can expand it into a door and lead to new directions.

"You can do it again tomorrow, Yuan Gong said that there is a heavy rain tonight." Li Yuanying is no longer a admirer of Du Che's workaholic nature, but a little jealous. Compared with him, Xiao Ruoyuan belongs to the category of normal people...... For the sake of the future high-speed rail, scud and Dongfeng Express, as well as the little wings flying around the water blue ball, a certain should take action to prevent him from overwork...... Reminded softly. "It's just as important to observe the changes in the river as it is to the capacity of the new bridge."

For Toshiro, the observation data is equivalent to rest.

Yuan Tiangang's eyes were slightly condensed, King Teng's eccentric eyes were not ordinary eccentric eyes, they were quite eccentric eyes! When we do things, we can't wait to get results immediately, how can we get here to Du Si and we can do it again tomorrow? Where can Du Si use the observation data, it is obvious that he wants to let him rest!

"Whoa." Du Che turned around and saluted with his hands and said softly. "Then I'll let the second senior brother prepare the yang qi first, and it will take time for Sun Gong to make the wheel."

It's good that he still understands it, not to mention that there is still a lot of worry in King Teng's eyes...... If you can have such a confidant in life, what more can you ask for? It's a hexagram...... What, the turtle shell has been burned somewhere? It's easy to find turtle shells, there are a lot of them in the third senior brother, and there are also all kinds of vintages.

Li Yuanying secretly breathed a sigh of relief, it was good to go to the end without a single tendon, waved his hand, and said with a casual smile: "Then you will go and deal with the wild boar with Xiao Shiyi, looking at his appearance of not eating fireworks in the world, I am really afraid that he will abuse the pig." ”

Du Che couldn't help but laugh and sang, and turned to leave. Eleven just doesn't seem to be eating the fireworks of the world, and the person who is the best at eating in the Shushan Sword Sect is none other than him, after all, he wants to make sure that his handsome and miserable face will not be damaged by eating......
